  • FIG. 3 is an enlarged fragmentary view illustrating the drive mechanism for the pipe spinning rollers
  • FIG. 7 is a fragmentary detail view in elevation illustrating an adjustable roller in an alternate position as compared with the position of FIG. 6;
  • FIG. 8 is a fragmentary detail view in section, as taken on the line 8-8 of FIG. 2, showing the lever end adjustor mechanism
  • the adjustable power spinning tong of the present invention will be seen to generally comprise a suitable frame structure 1 on which is mounted a drive motor 2, in the illustrative embodiment shown as a typical air motor.
  • a drive motor 2 in the illustrative embodiment shown as a typical air motor.
  • Pivotally mounted on the frame 1 is a pair of elongated levers 3 and 4 which are pivoted about a common axis 5.
  • the levers have elongated arms 6 extending along side the frame 1 and constituting actuating lever arms, whereby pipe gripping lever arms 7 are adapted to be moved toward and away from one another into and from gripping engagement with a pipe P.
  • the drive rollers 8 are adapted to be driven in either direction by the motor 2 to effect rotation of the pipe P when the pipe is gripped between the rollers 8 and 9 as seen in FIG. 1.
  • the rollers 8 and 9 are formed of or covered by an elastomeric material which is resiliently deformable under pipe gripping pressure and provides a good friction grip of the pipe, as is well known.
  • the levers 3 and 4 are adapted to be actuated about the pivot S by actuator means, generally denoted at 10, operable to move the actuating lever arms 6 outwardly to close the gripping lever arms 7, and operable to retract the operating lever arms 6 to open the gripping lever arms 7.
  • the actuator means 10 includes an expander wedge or block 11 which is slideably disposed with respect to the frame I and connected to an actuator rod 12 which projects from an actuator cylinder 13, the cylinder 13 being fixed to the frame 1 by tie bolts 14.
  • Each of the levers 3 and 4 has, at the outer end of its operating arm 6, adjustable means 15 supporting a roller l6 engageable by opposing wedge surfaces 17 of the wedge block 11, whereby the lever arms are actuated in a pipe gripping direction when the actuator rod 12 is extended. Also carried by the adjustable means 15 is a lever retracting link 18 engageable with the wedge block ll to retract the levers from the gripping engagement with the pipe in response to longitudinal movement of the wede block ll when the actuator rod 12 is retracted.
  • the purpose of the adjustor means [5, which will hereinafter described in detail, is to provide an adjustable link between the respective operating lever arms 6 and the rollers 16, whereby the lateral distance between the rollers 16 can be adjusted thereby enabling the wedge block 11 to cause the gripping jaws 7 to be closed on pipes of a range of sizes in response to the uniform short stroke of the actuator rod 12.
  • Such an adjustor structure not only enables the tong to be effectively utilized to spin pipes of a range of sizes, but also the short stroke actuator cylinder enables the overall size and mass of the spinning tong assembly to be minimized.
  • the levers 3 and 4 are mounted on the common pivot axis 5.
  • the lever 3 has a pair of vertically spaced webs or flanges l9 and and the lever 4 has a pair of vertically spaced webs or flanges 21 and 22 which horizontally lap or interfit with the webs or flanges l9 and 20 of the lever 3.
  • the frame 1 has a support section 23 disposed between the vertically spaced flanges l9 and 22 of the levers 3 and 4, respectively.
  • the respective flanges 19 through 22 are all journaled on a pin or shaft 24 which extends through the support frame section 23 and downwardly into a gear case 25 which houses the drive gearing, to be later described, by which the motor 2 drives the spinning rollers 8.
  • the spinning rollers 8 are adapted to be rotated in either direction to cause right hand or left hand rotation of a pipe frictionally engaged between the drive rollers 8 and the idler rollers 9 by suitable drive gearing as generally illustrated in F IG. 3, such gearing being located in the previously mentioned gear case 25.
  • the gearing includes an output gear driven by the motor 26 which is in mesh with an idler gear 27 which in turn drives a common gear 28 which is in mesh with a pair of idler gears 29, these idlers 29 respectively driving the drive gears 30 for the respective drive rollers 8.
  • the gearing system will be seen to be such that the drive rollers 8 are driven in the same direction so that their engagement with opposite sides of the pipe will cause the pipe to be driven in a selected direction depending upon the direction that the motor 2 is driven.
  • rollers 9 are adjustably mounted by means which enable each of the rollers 9 to be mounted either in a first position (FIG. 6) relative to the roller 8 on its gripping arm 7 or a second position (FIG. 7) closer to the roller 8, whereby to effectively cooperate with the opposing rol lers to grip pipe of a range of sizes.
  • the roller 9 is suitably rotatably supported upon a pin or shaft 31 which spans upper and lower flanges 32 and 33 of the gripping arm 7.
  • a head 34 of the pin 31 is generally rectangular in form and the pin is off center with respect to the head.
  • the flange 32 has a rectangular seat 35 which receives the head 34.
  • end projections 36 which extend into recesses 37 in the flange 32 at the ends of the seat 35.
  • the lower flanges 33 has a bore 38 and a seat 39 to receive a bushing 40 having an off center opening 4! receiving the pin 31.
  • a retainer 42 is employed beneath the flange 33 to retain the bushing 40 and the pin 3
  • the adjustor means 15 which support the wedge rollers 16 to vary the width between the rollers 16 comprises, in the case of each of the levers 3 and 4, the assembly best seen in FIGS. 8 and 9.
  • the operating lever arm 6 has a slot 43 in its end, and a crank 44 is disposed in the slot 43 and pivotally mounted on a pin 45 which spans the slot 43.
  • One arm 46 of the crank 44 is slotted at 47 to receive the roller 16 which is mounted for rotation on a pin or shaft 48 spanning the slot 47.
  • the other arm 49 of the crank 44 is slotted at 50 to receive the head 51 of an adjustor screw 52.
  • a quick-releasable pin 53 extends through the head 5] and connects the adjustor screw to the crank arm 49.
  • the adjustor screw 52 is threaded into an adjustor link 54 which is pivotally mounted upon a pin 55 carried by the lever arm 6.
  • the adjustor screw 52 can be rotated with respect to the link 54 to effectively increase or decrease the distance between the pins 53 and 55, thereby moving the roller 16 towards or away from the wedge block 11.
  • the levers 6 are spread more or less, depending upon the adjustment of the adjustor means 15 so that the rollers 8 and 9 will be operable to engage and spin a variety of pipe sizes.
  • the links 18, previously referred to are adapted to retract the actuating lever arms 6.
  • the links 18 are pivotally mounted at 18a on the shafts or pins 48 which support the wedge rollers 16.
