Abstract

The utility model relates to the technical field of testing devices, in particular to a back-up tong for a petroleum pipe make-and-break testing system. Back-up tongs in the prior art cannot meet the requirements of tubular columns with different size. For overcoming the shortages in the prior art, the technical scheme is that the back-up tong for the petroleum pipe make-and-break testing system comprises a tong body and a tong jaw, the tong jaw comprises a fixed tong jaw and a movable tong jaw hinged to a front section of the fixed tong jaw, and tong teeth are arranged on the inner side of the movable tong jaw and in detachable connection with the movable tong jaw. The back-up tong for the petroleum pipe make-and-break testing system is simple in structure, low in production cost, easy to manufacture and reliable in clamping performance.

Description

A kind of petroleum pipeline make-and-break test system uses back-up tong
Technical field
The testing arrangement technical field that the utility model relates to is specifically related to a kind of petroleum pipeline make-and-break test system and uses back-up tong.
Background technology
In oil field drilling engineering and correlation test, in petroleum pipeline make-and-break test system back-up tong be used for the make-and-break test system the supporting use of Power Tong, realize that the automatically synchronous clamping of back-up tong and Power Tong unclamps the oil tubing string synchronously.The back-up tong of prior art comprises vice body and jaw, and the jaw inboard is fixed with the pincers tooth, pincers tooth the outer face be used for fixing tubing string.Tubing string size because of required clamping in the actual experiment process is different, need be equipped with the pincers tooth of all size, and needs often to change, and works together and inconvenience, causes unnecessary trouble, waste of manpower and material resources.
The utility model content
The utility model provides a kind of petroleum pipeline make-and-break test system to use back-up tong, can't satisfy the shortcoming of different tubing string sizes with the back-up tong that overcomes prior art.
For overcoming the deficiency that prior art exists, the technical scheme that the utility model provides is:
A kind of petroleum pipeline make-and-break test system uses back-up tong; Comprise vice body and jaw; Said jaw comprises regular jaw and the moving jaw that is hinged on the regular jaw leading portion, and said moving jaw inboard is provided with the pincers tooth, it is characterized in that: said pincers tooth and moving jaw are for removably connecting.
Above-mentioned pincers tooth is connected through oat tail groove structure with moving jaw.
Above-mentioned pincers tooth is connected through bolt with moving jaw.
Compared with prior art, the utility model has the advantages that:
1. pincers tooth and moving jaw are convenient for changing the pincers tooth for removably connecting according to the test needs.
2. the pincers tooth is connected through oat tail groove structure with moving jaw, has simple in structurely, and cost of production is low, is easy to manufacturing, the advantage of clamping dependable performance.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Description of reference numerals is following:
1-vice body, 2-regular jaw, 3-moving jaw, 4-clamp tooth.
The specific embodiment
To combine the many utility model of accompanying drawing at length to explain below.
Referring to Fig. 1; A kind of petroleum pipeline make-and-break test system uses back-up tong, comprises vice body 1 and jaw, and said jaw comprises regular jaw 2 and the moving jaw 3 that is hinged on regular jaw 2 leading portions; Said moving jaw 3 inboards are provided with pincers tooth 4, and pincers tooth 4 and moving jaw 3 are for removably connecting.Above-mentioned pincers tooth 4 can be connected or the bolt connection for oat tail groove structure with the mode of removably connecting of moving jaw 3.
Be oat tail groove structure in the present embodiment, when changing pincers tooth 4, only need former pincers tooth 4 can be taken out along slippage in the dovetail groove that is provided with on the moving jaw 3, then need with pincers tooth 4 slide onto the installation site along dovetail groove and get final product.
