A number of apparatuses or machines for making and breaking joints in drill pipe strings are known. A superior and commercially successful machine is the HAWKJAW apparatus available from Hawk Industries of Long Beach, Calif. Versions of it are described in U.S. Pat. No. 5,060,542 (Hauk), No. 5,386,746 (Hauk), and No. 5,868,045 (Hauk). The HAWKJAW apparatus (or machine or power tong) including both the HAWKJAW JR. and SR. models, are disclosed in the “HAWKJAW Operation, Maintenance and Service Manual,”(Model 100K-ALS-REV 12,99.9200) and “HAWKJAW Operation, Maintenance and Service Manual,Model 65K-ALS, June 2000.” (The above-mentioned patents and publications and all other patents and publications mentioned anywhere in this disclosure are hereby incorporated by reference in their entireties.)

Basically, the HAWKJAW apparatus includes a structural frame supporting three wrenches (or jaws or grippers) aligned one on top of the other. The top and bottom wrenches are in the same orientation, and the middle wrench is in a flipped over orientation. Each of the jaws is operated in only one direction and is self-energizing. The HAWKJAW apparatus uniquely allows the drill pipe string to be made up (torqued up) and to be broken out using the same machine and without having to reposition the wrenches relative to the frame for the different operations. Further, a spinner can be provided at the top of the frame to spin the top pipe section out of the drill pipe string once the wrenches have broken the joint connection. In other words, the HAWKJAW apparatus is a device to connect and disconnect drill pipe on the rig floor while tripping, and/or to make and break other connections on the drill rig floor, including small, big and short connections. It is a versatile system. The spinner spins the connection to the shoulder so that the wrenches can take over and torque it up. And, after the connection has been subsequently broken by the wrenches, the spinner can spin it out at low torques to disconnect it.

On the make-up cycle of the HAWKJAW apparatus the structural frame moves about the centerline of the drill pipe string, approximately fifty degrees. This movement is due to the fact that the middle wrench is gripped on the bottom section of the drill pipe string that is rigid to the well. The torque cylinder is hooked to the middle wrench that is gripped on the bottom connection. The top wrench is gripped on the top connection and must turn, and is part of the infrastructure of the HAWKJAW apparatus. As the middle wrench is gripped, it stays rigid on the bottom connection, and the HAWKJAW apparatus (or more specifically the structural frame thereof) which is gripped on the top connection, rotates as the drill pipe is making up. The bottom section of the pipe is not moving; it can be generally 6,000 to 10,000 or so feet below it and thus is rigid in the derrick and does not turn. The only thing that turns is the top connection of the drill pipe string.

The torquing load is placed on the middle wrench and either the top or bottom wrench by the hydraulic torque cylinder. Thus, in the making-up operation the middle wrench is connected to the bottom section of the pipe, which is fixed, and with the torque applied between the structural frame of the HAWKJAW apparatus and the fixed middle wrench, the structural frame with the top wrench connected thereto rotates about the centerline of the drill pipe string. In contrast, in the break-out operation the middle wrench is connected to the upper pipe section and the bottom wrench is connected to the lower pipe section. The torquing cylinder applies a load between the middle and bottom wrenches and the middle wrench turns the upper pipe section. The structural frame does not thereby rotate around the centerline of the drill pipe string.

The need for additional torque cycles to properly torque the connection for the drill pipe is especially significant with the HYDRIL pipe which has a wedge thread, providing a tapered drill pipe connection for the joint tool connection. Thus, as the two pieces of pipe are screwed together, the interference fit therebetween becomes progressively tighter. It takes more than fifty degrees to torque this wedge-type thread and more particularly, takes anywhere from one hundred and fifty to one hundred and seventy-five or two hundred degrees to torque the connection out. In contrast, a normal connection needs a torque of thirty-five to forty degrees to make up. Thus, three to six time-consuming grip-torque-release cycles are required to make the HYDRIL pipe with the prior art HAWKJAW apparatus.

Many of the inventions herein are directed to remedying the problems discussed above. The pipe making and breaking apparatus disclosed herein preferably includes three pipe gripping wrenches, as described the HAWKJAW apparatus above and incorporated in this invention summary. When the apparatus is in the “make” mode the middle wrench is gripped on the bottom pipe section and the top wrench is gripped on the top section, and when in the “break” mode the bottom wrench is on the bottom section and the middle wrench is on the top pipe. (Alternatively, the middle and top wrenches can be mirror images of the orientations as disclosed herein and the middle wrench can be flipped over compared to the orientation disclosed. Then the middle and top wrenches will be used for break and the middle and bottom for make.) A novel “grip hold” function is provided by the present invention such that when a detented grip hold button (or the like) is pushed, as by the machine"s operator, to its “on” position the wrench on the bottom pipe section remains gripped during the number of needed torquing operations of the wrench on the upper pipe section, because of a unique pneumatic/hydraulic system. The grip hold button (or lever, switch or other type of actuator) when actuated holds the bottom wrench on the break cycle and the middle wrench in the make cycle. The grip button holds the middle wrench on the break cycle and the top wrench on the make cycle. When the grip hold button is de-energized, the grip button is rendered inoperative.

The chain spinner, which can be part of this make/break apparatus or a separate unit, includes a unique chain oiler system. The spinner for example can be a free hanging, separate stand alone unit. The chain oiler is powered by fluid passing through the spinner motor. When the spray button is pressed the nozzle sprays hydraulic fluid onto the moving chain. The oil can thus only be sprayed when the spinner motor is turning and the chain is moving. Additionally, a chain guide is provided for the spinner chain to prevent the chain from bunching up and catching on the sprockets, which is a serious problem in the prior art. This chain guide is another invention disclosed herein. These chain oilers and guides can be adapted to fit on today"s spinners including the SPINMASTER spinner.

The pipe make/break apparatus of the invention is shown generally at 100 in FIG. 1 and is essentially an adaptation of the previously-described HAWKJAW apparatus. It includes a structural frame 110, a top wrench 120, a middle wrench 130, a bottom wrench 140, a spinner assembly 150 at the top and a hydraulic block 154 at the rear bottom.

The hydraulic system as depicted in FIGS. 7a-7 dfor the apparatus of FIG. 1, like a typical hydraulic system, has a pressure source or a flow source 160, a tank 170 for the excess oil that comes back, and a pump 180 that pumps the oil through the system. This system is essentially a closed system, with the exception of the chain oiler 190, as will described later. The hydraulic pump 180 preferably is a thirty-three gpm at 2,600 psi, which is about forty horsepower. An electrical motor 186 attached to the pump energizes the pump to pump the fluid. The air supply source 200 is preferably from the drilling rig and has a typical pressure of about one hundred psi.

With the apparatus 100 gripped on the pipe 300 and the middle wrench 130 in the make position (see FIG. 2) and ready to spin, the tilt cylinder 294 cannot be actuated, the winch 310 cannot be actuated and the raise and lower cylinder 320 cannot be actuated. The air valves that control the hydraulic cylinders and the motors that power these components are disabled, as will become more apparent from further explanations provided and with reference to the schematics.

During the making procedure, the top wrench 110 and the middle wrench 120 are gripped on the pipe 300. When the torque cylinder 340 is extended, the middle wrench 120 extends. The grip hold button 220 keeps the apparatus 100 gripped on the pipe 300 while the wrench comes back by retraction of the torque cylinder 340 and goes through as many additional torque cycles as may be needed. After a torque cycle and the grip button 230 has been released, but with the grip hold button 220 still actuated, the middle wrench 120 stays gripped. When the grip button 230 is pushed, the torque button 250 can be pushed to torque again. All the while, however, the middle wrench 120 stays gripped on the pipe, due to the actuation of the grip hold button 220. This prevents the entire apparatus 100 from coming off the pipe 300 and having to be pushed on to it and gripped again for another torque cycle (as described above for the prior art HAWKJAW apparatus).

The grip hold button 220 allows the system to stay on the pipe as it goes through its torquing cycles. When the grip hold button 220 is pushed, the tilt button 232 will not work nor will the raise and lower buttons 236, 238. The winch 430 on the back of the unit 100 that hooks to the derrick and which allows the unit to come on the pipe and to be pulled away will also not work. In other words, the apparatus is thereby protected against being pulled off of the pipe 200 when the middle wrench 120 is gripped. The middle wrench 120 is basically a floating wrench, and is spring loaded into its default position. If the middle wrench 120 were gripped and the apparatus 100 were pulled away from the pipe 200, the middle wrench 120 would be pulled away from the (HAWKJAW) apparatus and this would damage the system.

The earlier-described prior art HAWKJAW apparatus, over which the inventions disclosed herein are extensions and improvements, only had a grip button. Pursuant to one aspect of the present invention, the apparatus has a grip button 230 and a grip hold button 220. The reason for having these two buttons is because the grip hold works to allow the middle or bottom wrench gripped on the pipe 200 independent of the other wrenches that do the torquing. The grip hold button 220 causes the bottom wrench 120 to grip; the bottom wrench does not rotate and defines a stationary connection. The grip button 230 grips the wrench that does the rotating. If the grip hold button 220 is de-energized, the grip button 230 is made inoperative. However, the operator can raise or lower the machine 100, actuate the winch, or tilt the apparatus. The spinner motor cannot be operated because it has to be gripped on the pipe to spin. When the grip hold button 220 is pushed the spin button 260 can be pushed and the spinner actuated.

The SPINMASTER spinner can be used on other pieces of equipment aside from the HAWKJAW apparatus; alternatively, it can hang on its own. When it is on its own, separate from the HAWKJAW apparatus, the controls and the system can be entirely hydraulic, without any pneumatic component. This is shown, for example, by the circuit of FIG. 15. The spinner has to be running on the pipe and turning the pipe—that is, the spinner motor 370 pressurized—before the oil will spray on the chain 400 as previously described. That is, the motor pressure must be on, so as long as there is pressure to the spinner motor, the sprayer will work with the spray button 234 pushed. If the apparatus is torqued up on the pipe and the spinner motor 370 stops and the connection is shouldered up but the motor has pressure to it, the sprayer will still spray.

The present onboard spraying system allows the chain 400 to be lubricated, for example, on a daily basis before the operator starts to spin the pipe and also to be lubricated at the end of the day before shutdown. It is anticipated that this effective user-friendly lubrication system will double or triple the chain life. Additionally, it maintains spinner power; this is because when a chain starts corroding, the power of the spinner to torque the pipe is reduced.

The oiler only works when the spinner motor 370 is pressurized, as previously stated. Specifically, the oiler valve will not shift and allow oil to come up into the spray nozzle 380 and spray on the chain unless the motor is pressurized. The fluid flows out of the hydraulic system—out the spray nozzle 380 onto the chain as the motor is turning. It is powered by fluid going through the spinner motor 370. The nozzle is spraying the hydraulic fluid which comes from the power unit tank (which has about one hundred gallons capacity). It only sprays for about a second and a half and applies one-twentieth of a gallon for each spray. The user may spray once a day or once a week, for example.

The present oiler system is advantageous because oil is not sprayed on a non-moving chain. The oiler button 234 is only effective when the chain is moving so that the spray can cover the entire chain 400 with a coating of oil as it is operating. If the chain 400 is not moving while the oil is bring sprayed on it, the oil will just drip down and ineffectively/inefficiently lubricate and will tend to exhaust the oil supply. Thus, the button 234 is only enabled when the spinner is operating on a pipe. The fluid that is sprayed is the hydraulic fluid of the HAWKJAW apparatus, the SPINMASTER apparatus, the power unit of the HAWKJAW apparatus or the rig unit.

The company’s focus on vertical drilling equipment has paid off. It was awarded Manufacturer of the Year at the 2014 Oil & Gas Awards and it holds several patents for its innovative products. The company produces four main lines, the T-WREX, T-WREX Junior, HAWKJAW and SPINMASTER, and among these products Hawk Industries is able to cover a gamut of needs.

The HAWKJAW is Hawk Industries’ flagship product and has been continuously improved after years of design and testing. The make-up/break-out tool combines spinning and torque wrenches in a modular design for easy maintenance and servicing. It has a self-energized grip system and optimizes drill crew size by combining tongs, spinner and spin chains into a single unit. The HAWKJAW also improves safety with fewer cables, snub lines and pull chains required on the rig floor.

The T-WREX and T-WREX Junior feature the HAWKJAW on a pedestal-mounted configuration for remote operations. It’s ideally suited to the harsh environments of offshore drilling or large-scale land-based operations. The SPINMASTER, which the company says is one of the fastest, safest and most efficient drill pipe spinners on the market today, is available in pneumatic or hydraulic models and in two sizes. It has a high torque output of 2,272 feet per pound while its compact design makes it lighter than comparable tools. Allshouse says that all of its tools are designed for maximum flexibility.

“We try to design products that you can use on any vertical rig,” Allshouse says. “Like the HAWKJAW, it was designed to move from rig to rig, so it’s easy to take down and easy to put away. All the product lines use the same spare parts, so if you have a HAWKJAW and a T-WREX, you can interchange spare parts. We really focus on availability of parts to get the customers what they need for after-sales service and on designing flexibility into our equipment.”
