Abstract
The utility model discloses a chain type torque tong which comprises a pulling ring, a chain axis, a chain, a chain hook, a tong key, a tong head, a torsion head, a torque arm, a finger, a dial, a scale, a digital, and a handle, and the utility model is characterized in that an additional chain tong head is arranged on the torsion head; the inclined lower part of the tong head is arranged with an obverse tong key and a reverse tong key; wherein the left side of the tong key is arranged with the chain, and the upper side of the tong head is arranged with two chain hooks; while the chain axis on the chain has certain length projected out of the two sides of the chain sheet, and the tail end of the chain is the pulling ring. The utility model has a rated torque of 300 N/m and has the advantages of simple structure, easy manufacturing, and convenient, safe and reliable operation, which can be applied to various oil pumping well heads and other fields. The utility model also has the advantages of making the packing set reached proper degree of the tightness for extending the service life of the packing set, thereby reducing the frication load of the oil pumping well and saving electric energy.
Description
Technical field
The utility model relates to the tight packing specific purpose tool of a kind of rod-pumped well, particularly is a kind of chain-type torque tong.
Background technology
The oil motor-pumped well in process of production, the degree of tightness of well head packing is very important, cross loose well head leakage of oil, tension not only burns packing and increases the oil pumper frrction load, power consumption increases, how to make the rod-pumped well degree of tightness appropriateness of well head packing in process of production? still do not have specific purpose tool, can not measure moment, the post workman can only decide with sensation, and prior art can not address the above problem.
Summary of the invention
Technical problem to be solved in the utility model is a kind of chain-type torque tong of design, solves the problem that exists in the tight packing work of rod-pumped well.
The technical scheme that its technical problem of solving the utility model adopts comprises: draw ring, chain rivet, chain, chain hook, pincers tooth, binding clip, turn one's head, torque tube, pointer, dial, scale, numeral, handle; It is characterized in that: described on turning one's head, setting up a chain tongs binding clip, the oblique below of binding clip is provided with positive and negative pincers tooth, so that positive and negative usefulness, the left side at the pincers tooth is provided with chain, the top of binding clip is provided with two chain hooks, chain rivet on the chain respectively protrudes certain-length on the Chain link for chain grate both sides, so that tangle with chain hook, the tail end of chain is a draw ring.
Chain-type torque tong according to the such scheme manufacturing, 300 Ns of nominal torques. rice, simple in structure, make easily, easy to operate, safe and reliable, be suitable for various pumpingh well well heads, make packing reach the degree of tightness appropriateness, prolong packing service life, reduce the rod-pumped well frrction load, saves energy has good economic benefits.
Description of drawings
The utility model master TV structure schematic diagram.
In the accompanying drawing, the 1-draw ring, the 2-chain rivet, the 3-chain, the 4-chain hook, 5-clamps tooth, the 6-binding clip, 7-turns one's head, 8-torque tube, 9-pointer, 10-dial, 11-scale, 12-numeral, 13-handle.
The specific embodiment
The utility model comprises: draw ring 1, chain rivet 2, chain 3, chain hook 4, pincers tooth 5, binding clip 6, turn one's head 7, torque tube 8, pointer 9, dial 10, scale 11, numeral 12, handle 13, decorative pattern 14; It is described for setting up a chain tongs binding clip 6 on 7 turning one's head, the oblique below of binding clip 6 is provided with positive and negative pincers tooth 5, is provided with chain 1 on the left side of pincers tooth 5, and the top of binding clip 6 is provided with two chain hooks 4, chain rivet 2 on the chain 1 respectively protrudes certain-length on the Chain link for chain grate both sides, and the tail end of chain 1 is a draw ring 1.
Use method of operating: at first, binding clip 6 is placed on the packing box, chain rivet 2 and chain hook 4 are tangled; Secondly, can carry out fastening to packing with hand turning handle 13.The general new packing 20-30 ox that adds. rice, old packing 40-50 ox. rice gets final product.The chain-type torque tong can also be used for other occasion in addition.
