Abstract
The utility model relates to a top drive drill element of an oil well drilling, in particular to a back-up tong of a top drive drilling device, which comprises a swiveling head connecting flange, a connecting sleeve, a twisting force sleeve, a master oil cylinder, a back-up tong, a left tong body and a right tong body, wherein a pin which is arranged on the opening of the top end of the twisting force sleeve is connected with the swiveling head flange of the top drive device, the lower end is connected with the connecting sleeve through a block, the back-up tong uses the back-up tong pin to penetrate through the tong body and is fixed on the connecting sleeve, the controlling oil cylinder is mounted on the upper portion of the twisting force sleeve, the lower portion is provided with a main body piston of the back-up tong and a dental lamina, and the upper and lower end surfaces of the back-up tong are provided with disk springs. The device is convenient for installation and maintenance and more convenient for disassembly when a tong tooth is replaced. When the back-up tong tightly clips a drilling rod button, the tong tooth can not move from bottom to top. The utility model can prevent the tong tooth from disengaging from the tong body, and meet the needs of drilling.
Description
Technical field:
The utility model relates to a kind of oil drilling top drive drilling machine parts, especially a kind of back-up tong that is used for top-drive drilling.
Background technology:
Enter the nineties in last century top drive drilling machine and enter the stage of popularization at world wide, this equipment has unique advantage for improving bit speed and quality, but in use still exist deficiency as the back-up tong parts especially, for example temperature is hanged down under the situation in the winter time, freeze, clamp shortcomings such as tooth is short, clamping force is little, piston can not move easily and break down, can not satisfy instructions for use to making.
The utility model content:
The utility model purpose is a kind of back-up tong that is used for top-drive drilling that provides in order to overcome above-mentioned shortcoming.Can conveniently carry out and make the screw thread clamping force more reliable, prevent to clamp the upper and lower play of tooth and break away from caliper.
The technical scheme of utility model:
The task of Ti Chuing for achieving the above object, the utility model is made up of Torque sleeve, control oil cylinder, branch sleeve, back-up tong, swiveling head adpting flange, left caliper, right caliper body; The bearing pin that described Torque sleeve top end opening place is provided with is connected with top driving device swivel coupling adpting flange; The lower end links to each other with branch sleeve with flat key, and described back-up tong adopts the back-up tong bearing pin to pass back-up tong, enters in the branch sleeve, fixes with horizontal block in branch sleeve.The Torque sleeve inside upper part is equipped with IBOP control oil cylinder, and the bottom is provided with the back-up tong main body that is made of left and right two calipers, is provided with piston, dental lamina seat, dental lamina in the left and right caliper.On the every back-up tong bearing pin at the upper and lower end face place of back-up tong, some groups of disk springs are housed; Left and right sides caliper is an opposite opened, and profile is square.During work, the left and right caliper of back-up tong is connected with bearing pin, the hydraulic oil of control oil cylinder promotes piston forward and moves and finish shackle and clamp action during last shackle, and hydraulic oil promotes that piston is mobile backward to be resetted then; When changing parts, caliper one side bearing pin is pulled down, whole back-up tong is inclined out, can change pincers tooth and tool joint and finish other operation.
The utility model compact conformation, but back-up tong is provided with the left and right caliper of symmetry open type, adopt direct selling back-up tong bearing pin directly to pass back-up tong and enter branch sleeve, fix like this when changing the pincers tooth at the horizontal block of adding on the branch sleeve, more convenient, in addition owing on the every back-up tong bearing pin in the upper and lower end face place of back-up tong, some groups of disk springs are housed all, like this when back-up tong clamping drill pipe coupling collapses button or links closely, back-up tong is play relatively, prevent that whole top from driving action of gravity on the pincers tooth, cause pincers tooth upper and lower play.
Description of drawings:
Fig. 1 is the utility model assembling schematic diagram.
Fig. 2 is, the utility model view of inclining out.
Fig. 3 is back-up tong clamped condition schematic diagram.
Among the figure by 1, the swiveling head adpting flange, 2, bearing pin, 3, Torque sleeve, 4, key piece, 5, branch sleeve, 6, back-up tong, 7, back-up tong bearing pin, 8, the control oil cylinder, 10, block, 12, disk spring, 13, left caliper, 14, right caliper body, 15, piston, 16, the dental lamina seat, 17, dental lamina, 18, spring, 19, big bearing pin forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing:
As shown in the figure: this device assembled relation in this way, the bearing pin 2 that Torque sleeve 3 top end opening places are provided with is connected with the swiveling head adpting flange 1 of top driving device, in the time of need inclining out, can incline out along the bearing pin of opening part.Do not rotate with swiveling head.Link to each other with branch sleeve 5 with key piece 4 in Torque sleeve 3 lower ends; described back-up tong 6 adopts back-up tong bearing pin 7 to pass caliper; in branch sleeve 5, fixed by being located at branch sleeve internal stop 10; like this when changing pincers tooth or protection pipe nipple; installing/dismounting back-up tong bearing pin is convenient; in Torque sleeve 3 inside upper part IBOP control oil cylinder 8 is housed; two calipers 13 about the bottom is provided with; back-up tong 6 main bodys that 14 (Fig. 3) constitute; be provided with piston 15 in the caliper of the left and right sides; dental lamina seat 16; dental lamina 17; when last shackle; control oil cylinder 8 promotion pistons move backward and reset; on back-up tong 6; some groups of disk springs 12 are housed on the every back-up tong bearing pin 7 at place, lower surface like this when back-up tong clamps drill pipe coupling or tight screw thread; back-up tong is play relatively; the action of gravity that prevents from whole top to drive is on the pincers tooth; cause on the pincers tooth; following play breaks away from caliper.
Described left and right sides caliper 13,14 is an opposite opened, and outward appearance is square.
