Abstract
Concentric tube drawbench, which is clamped, the utility model discloses a kind of clamping clip and roller clamps hand, it includes clamping clip, roller clamps, roller pincers are installed in the lower section of clamping clip, array pincers dental assembly is mounted on the left and right pincers of the clamping clip, pincers dental assembly includes the pedestal being fixed in left and right pincers, and two groups of arc shaped pincers teeth are symmetrically installed with pedestal；Several fixing axles are symmetrically installed with the left and right pincers of roller pincers, are evenly equipped with several rollers in every fixing axle from top to bottom, roller can be rotated around fixing axle；The radius of roller is identical with the arc radius of arc shaped pincers tooth, and the center of circle is located on same vertical line.The utility model when clamping the drilling tool of different tube diameters, clamping clip and roller pincers can operation at the same time, the concentricity of drilling tool is high, time saving and energy saving, improves the operating efficiency of tube drawbench.
Description
Technical field
Oil drilling and extracting equipment technical field is the utility model is related to, specifically a kind of clamping clip and roller clamp concentric
Tube drawbench clamps hand.
Background technology
Column tube drawbench clamping hand includes clamping clip, roller pincers, safety tongs three parts, and clamping hand uses link-type knot more
Structure, its advantage are adaptable to the caliber of clamped drilling tool, can handle the larger drilling tool of caliber scope.Shortcoming is when clamping
When clamping the drilling tool of different tube diameters, clamping clip and roller clamp after clamping drilling tool respectively hand, the center of two drilling tools occur not afterwards
The problem of coaxial.At the scene during operation, in order to overcome the problem, the general usage for clamping hand is that roller pincers first act, by drilling tool
Primary Location centering is carried out, clamping clip reoperates, and clamps drilling tool.This operating type can not ensure two differences of docking
Caliber drilling tool it is concentric, it is time-consuming and laborious.
Utility model content
The mesh of the utility model is to provide a kind of clamping clip and roller and clamps concentric tube drawbench clamping hand, to solve clamping hand
In the drilling tool of two different tube diameters of clamping the problem of drilling tool decentraction.
To reach above-mentioned purpose, technical solution adopted in the utility model is：
A kind of clamping clip and roller clamp concentric tube drawbench clamping hand, it includes clamping clip, roller clamps, and roller pincers are installed on
The lower section of clamping clip, array pincers dental assembly is mounted on the left and right pincers of the clamping clip, and pincers dental assembly includes being fixed on a left side
Pedestal in right jaw, is symmetrically installed with two groups of arc shaped pincers teeth on pedestal；It is symmetrically installed with the left and right pincers of roller pincers several
Fixing axle, is evenly equipped with several rollers in every fixing axle, roller can be rotated around fixing axle from top to bottom；The radius of roller with
The arc radius of arc shaped pincers tooth is identical, and the center of circle is located on same vertical line.
Preferably, at least one group of pincers dental assembly on each jaw of the clamping clip, roller pincers each jaw up to
Rare one group of corresponding roller.
The course of work of the utility model is：
The power set of clamping hand make the caliper of clamping clip, roller pincers clamp tooth and roller to drilling tool to intermediary movements respectively
Apply pressure, so as to clamp drilling tool.When clamping clip, roller pincers clamp the drilling tool of different tube diameters at the same time, clamped drilling tool exists
Concentric roller coincides with axle center under the action of arc shaped pincers tooth, and the roller on roller pincers jaw is rotated around fixing axle, is used for
To the compensation of thread of drilling tool rotary force during upper shackle.
The beneficial effects of the utility model are：
The utility model clamp different tube diameters drilling tool when, clamping clip and roller pincers can at the same time operation, drilling tool it is same
Axis degree is high, time saving and energy saving, improves the operating efficiency of tube drawbench.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of clamping clip and roller as shown in Figures 1 to 5 clamps concentric tube drawbench clamping hand, it includes clamping clip 1, rolling
Son pincers 2, roller pincers 2 are installed on the lower section of clamping clip 1, are mounted on two groups of pincers dental assemblies 3 on the left and right pincers of clamping clip 1, clamp
Dental assembly 3 includes the pedestal 6 being fixed in left and right pincers, and two groups of arc shaped pincers teeth 5 are symmetrically installed with pedestal 6；A left side for roller pincers 2
Two fixing axles 7 are symmetrically installed with right jaw, are evenly equipped with several rollers 4 in every fixing axle 7 from top to bottom, roller 4 can be around
Fixing axle 7 to rotate；The radius of roller 4 is identical with the arc radius of arc shaped pincers tooth 5, and the center of circle is located on same vertical line.
The course of work of the utility model is：
Clamping clip 1, roller pincers 2 at the same time clamp the drilling tool of different tube diameters when, clamped drilling tool concentric roller 4 with
Axle center coincides under the action of arc shaped pincers tooth 5, and the roller 4 that roller is clamped on 2 jaws is rotated around fixing axle 7, during for upper shackle
Compensation to thread of drilling tool rotary force.
The utility model clamp different tube diameters drilling tool when, clamping clip and roller pincers can at the same time operation, drilling tool it is same
Axis degree is high, time saving and energy saving, improves the operating efficiency of tube drawbench.
