11 Claims.
The present invention is directed to a device for rotating a cylindrical member about its longitudinal axis. More particularly, the invention is directed to an improved device for spinning pipe.
Heretofore the practice has been, when making up and spinning pipe to be used in well boring operations, to employ a spinning chain which is given several turns around a tool joint of the pipe stands to be made up. The spinning chain is ordinarily attached to a wire line or cable running to a cathead which takes up the slack and exerts tension thereon. As a result, the spinning chain which is wrapped around the pipe stand to be made up into the tool joint thereof is rotated and spun up preparatory to the tonging action. The spinning chain employed in prior art practices requires the services of at least two men to stab the pipe in the joint and to engage the spinning chain with the pipe to be spun into position. Besides the requirement of manpower, use of spinning chain as employed in the industry prior to this invention was exceedingly hazardous due to the necessity of a man tailing the chain during spin-up operations. This often results in mashed or amputated fingers, and body injuries when the tail end of the chain is pulled off of the pipe. The action of the cathead in taking up slack and causing the pipe to be spun up into position also frequently caused the chain to whip across the derrick floor, which could easily result in decapitation or serious injury to personnel engaged in tasks on the derrick floor where such operations were usually conducted.
It is, therefore, the main object of the present invention to provide an improved spinning device which dispenses with the major part of manpower requirements.
A still further object of the present invention is to provide an improved spinning device which eliminates the hazardous features of the prior art practice.
Still another object of the present invention is to provide an improved spinning apparatus which is automatically set in position.
A still further object of the present invention is to provide an improved spinning chain having the property of expanding when tension thereon is released.
A still further object of the present invention is to provide an apparatus for rotating pipe and other longitudinal members which is set automatically.
Other objects of the invention will be illustrated by reference to the drawing in which Fig. 1 is a view of the apparatus of the present fill 2 invention as a stand of pipe is being lowered into the hole with slips in a raised position;
Fig. 2 is another view of the apparatus of Fig. 1 preparatory to stabbing a stand into a tool joint with the slips in a locked position;

Fig. 15 is an end view of the chain of Fig. 14.
The principal parts of the apparatus of the present invention comprise a cylindrical housing defining a helical or spiral runway adapted to be mounted on the periphery of a cylindrical memher, a vertical tubular member with a sliding collar arranged thereon and an alignment arm operably connecting the sliding collar with the spiral or helical runway. The apparatus of the present invention is particularly adapted to be employed with air operated slips.
Referring now to the drawing and particularly to Figs. 1 to 3 numeral l l designates a spiral cage or housing defining with its interior surface a helical runway which is adapted to be mounted on a cylindrical member such as a pipe stand I2, shown in 3, which is engaged with tool joint l3 and a second pipe stand 14. The housing II is provided with a cover plate IE to protect same from distortion and is attached by alignment arm I6 to a sliding collar I! which is slidably arranged on a polish rod or tubular member I8. Polish rod I8 may be mounted on air slips I9, which are conventional to the art, arranged on derrick fioor 2Q. Sliding collar I1 is spring loaded above and below by springs 2| and 22, the former being employed to cushion the sliding collar and the latter to cause the sliding collar to spring back into position as will be described. The polish rod I8 is provided with a slot 22a for a valve actuating mechanism 25 which is shown in detail in Figs. 8 and 9, as indicated schematically herein. Arranged in the spiral cage or housing I I defining a helical runway is a twisted flat length chain 23 with a thin strip of spring steel rigidly attached thereto on the outside thereof such as by welding to give the chain 23 the property of expanding when tension is released. Chain 23 is shown in detail in Figs. 14 and 15. The twisted flat length chain 23 with the thin strip of spring steel welded thereto is attached at one end to a cable 24 operatively connected to a cathead and by the other end by a wire line or cable 25 which connects it by sheave 23 to a conventional spring loaded drum or weight box 25a well known to the art.
Referring now to Fig. 4, it will be seen that the spiral cage or housing II is provided with welded round throat guides 21 and 28 to guide the spring loaded chain therethrough and also defines a guide throat 29 for guiding the cage I I over tool joints such as tool joint I3. It is to be understood that the cage II has a suflicient internal diameter to allow it to slide easily over tool joints such as illustrated in Figs. 1 to 3. It will be further seen that the housing I I comprises a plurality of runway members 30 defining a helical runway. In Fig. 4 five runway members are shown, but this may be a lesser or greater number as desired. A. larger number of runway members will lessen the chances of slippage of the chain and also will cause the pipe to be gripped tightly.
Referring now to Fig. it will be seen that runway member 30 is provided with rollers 3| which are inset therein by inserts 32. The rollers may be located approximately 4" apart to cause the spring loaded chain to move easily therearound. It will be further seen by referring to Fig. 5 that runway members 30 are connected to each other by tapers 33 which act as guides for the spring loaded coil or chain.
In Fig. 6 another embodiment of the roller installation is shown where the packing housing for the rollers is provided outside of the runway member 38. In this embodiment of Fig. 5 an 01?- set 34 defines a housing in which the rollers may rotate.
A detail of the alignment arm I6 attachment to housing I I is shown in Fig. 7.
Referring now to Fig. 8, the polish rod or tubu lar member I8 is provided with a valve actuating arm 55 which is locked on the interior thereof and communicates with the exterior of the polish rod I8 by slot 22A also shown in Figs. 1 to 3 and 10. Projectin through slot 22A and attached to a pivot 36 to valve actuating arm 35 is an actuating member 31 which through pivot 38 and valve arm 35 serves to operate a piston type valve 37A which connects to the air operated slips I9 and causes operation thereof. Fig. 8 also shows a locking member 38 which is provided with a releasing hand-operated lever 39 and. is attached by a spring loaded attachment 4!) to air slips I9 adjacent the polish rod I8 so that it may lock the 4 sliding collar II when the latter engages therewith.
In Fig. 11 a view is shown of a portion of a flat spring member 4I equipped with pipe dies 32 which may be used in lieu of the spring loaded chain 23.
Fig. 12 shows a cross sectional view of a wire cable 43 provided with a core of rubber 44 to provide resiliency thereof and allow it to be expanded.
Fig. 13 shows a view of a cable 45 in which is imbedded a flat spring 46 to provide the characteristics of expansibility to the cable 45 to be used in lieu of the spring load chain 23.
Figs. 14 and 15 show the spring loaded chain 23 comprising a strip of spring steel 4! with a twisted flat length chain 48 welded thereto such as used in the embodiments described with respect to Figures 1-8 inclusive.
The device of the present invention illustrated in the several figures may be operated as follows: For purposes of description it may be assumed that the device is best used in connection with oil well drilling operations where large numbers of pipe stands are employed and are lowered in the borehole during the course of such operations. When pipe is lowered into the hole the elevators coming down contact the spiral case or housing II which is protected by plate I5 causing the cage I I to be pushed downwardly and as the collar I'I engages with valve actuating member 31 causes the latter to be compressed inwardly through slot 22A. As a result, air valve 31A connected to valve actuating arm 35 causes the slips III to be set. Thus when the slips take the load of the pipe, the spiral cage is locked near the top of the slips by collar II, engaging with locking member 38 which is spring loaded and urged forward, thus holding collar I! and the cage I I near the top of the slips. The elevators are then brought up in the derrick and another thribble or pipe stand is picked up and stabbed into the pipe joint I3 as shown in Fig. 2. The floor man then presses the lever 39 of locking member 38 and releases locking member 38 from collar II which travels upwardly on tubular member [3 by virtue of being. urged upwardly by the spring member 22. As the collar I'I travels upwardly the slips are released by the collar again actuating the valve arm 35. The slips while released are still held in position due to the pipe load thereon.
The driller then causes the cathead, not shown in the drawing but connected to cable 24, to operate which exerts tension on the spring loaded chain 23. The spring loaded chain 23 then contracts against the pipe and spins it into position as shown in Fig. 3. By this time the tongs have been latched around the pipe and the pipe is tightened up in the tool joint. The drum or Weight bucket is released and the expanded chain is returned to position as the driller elevates the pipes to unset the slips. Another pipe is lowered, stabbed into position and the procedure may then be again repeated.
From the foregoing description taken with the drawing it will be seen that the apparatus of the present invention consists primarily of a spiral cage or housing having rollers on the inside thereof for the reduction of friction and a fiat chain with a welded strip on the outside thereof to impart the property of uncoiling when tension is released. Each spiral or housing member of the cage may be interconnected by an inverted V arrangement for guiding the flat chain into position. Each end of the spiral has circu- 8 1 three/ted line guides welded into the cage.
The top circle of the cage or housing is provided with a guide throat for centering the spiral as the pipe is lowered.
In operating the device one end of the chain is fastened to the spin-up cable on the cathea-d of the drilling rig while the other end of the chain is attached to a lighter cable that extends through a pulley arrangement to a spring loaded drum or weight box. If a weight box is employed, the cable and pulley arrangement may be extended to the first girt of the derrick. A brake or check may be provided to allow slack for tightening joints after spinning up. The brake or look may be operated by foot by the floor man operating the make-up tongs.
Thespiral housing or cage may be constructed of either round or angular members and equipped with rollers. For simplicity in installing rollers, an angular spiral may be more desirable. In lieu of rollers, ball bearings may be employed, but the former is preferred to the latter.
While the device of the present invention has been shown arranged on air slips, the apparatus may be employed without air slips and if desired the upright member l8 may be arranged on the derrick floor. When the apparatus of the present invention is employed without the employment of air operated slips, the valve arrangement including slot 22A, a valve actuating arm 35 and the actuating member 3'! may be omitted.
It is also desirable and preferable in some instances to employ two polish rods or tubular members [8 rather than one, as shown in Fig. 1. In such a case it would be desirable to have the housing or cage ll connected to the two polish rods by sliding collars such as I 1 and alignment arms such as 16, but in such a case only one of the tubular members or rods [8 need be provided with the actuating mechanism.
