Abstract
The utility model provides a front stabilizing device with T-shaped groove for top-drive back-up tong, which is characterized by good working property and long service life. The front stabilizing device comprises a front stabilizer, a spring is pressed on a step in the front stabilizer through a spindle, a bolt is used to fix a front end of the spring, a regulation cushion is used to press tightly the spindle at the other end of the spring, and a T-shaped member of the front stabilizer is sliding-connected with a valve. The front stabilizer and the valve are provided with a pair of T-shaped grooves for limiting displacement in Y and Z directions and external force, thus the spindle is only stressed by drag force and the structure is more reasonable, thereby increasing working reliability of back-up tongs, and extending service life of the front stabilizer.
Description
Technical field
The utility model belongs to the erection device in the petroleum and natural gas well drilling top drive back-up tong parts, relates in particular to the preceding erection device that the subsidiary T type groove of back-up tong is driven on the top.
Background technology
Along with the development and the application of top drive drilling technology, top-drive drilling integral body and supporting component thereof have obtained continuous improvement and perfect in production practices, and it also is like this that the parts of back-up tong improve.
For torque beam offset back-up tong, centralizer is generally all arranged, in drilling process, centralizer, torque beam and floating installation etc. are finished the support and the location of back-up tong jointly, and centralizer is made up of front and back two parts.For back-up tong, back centralizer is fixed, with regard to its function, preceding centralizer must have the function of floating along X-axis, with regard to the residing position of its back-up tong, in drilling process, preceding centralizer is all stressed on X, Y, three directions of Z, and the possibility that is subjected to displacement is promptly all arranged.If there is not T type groove, wherein the external force of directions X and corresponding displacement all have mandrel to come balance, wherein directions X is to be subjected to pulling force to mandrel, and Y, Z direction, and mandrel is to be in cantilever stress laterally or longitudinally, contrasting the structure of present other products, is insurmountable, is irrational.
The utility model content
The purpose of this utility model is to provide a kind of can follow back-up tong, favorable working performance, and the life-span, the preceding erection device of the subsidiary T type groove of back-up tong was driven on long top.
In order to achieve the above object by the following technical solutions: comprise preceding centralizer, spring is pressed on the step of preceding centralizer inside by mandrel, front end bolt, the other end use adjustment pad and mandrel to compress, and T type structure and valve on the preceding centralizer are slidingly connected.
T type structure on the preceding centralizer and the T type groove on the valve are slidingly connected.
T type structure on the preceding centralizer and two concave grooves to the symmetry of central opening on the valve are slidingly connected.
It is convenient that the utility model designs not only installation and maintenance, safe and reliable, and perfect back-up tong set upright function, considered the structure of preceding centralizer and valve on the whole, and the reasonability of the diameter of mandrel design, add a pair of T type groove at preceding centralizer and carrier valve thereof, then the displacement of Y, Z direction and external force all by the constraint of T type groove, make mandrel only be subjected to pulling force, and structure is more reasonable, increase the reliability of back-up tong work, prolonged the life-span of preceding centralizer.

The specific embodiment
Embodiment 1
As shown in Figure 1, 2, the preceding erection device of the subsidiary T type groove of back-up tong is driven on the top, centralizer 1, spring 2, adjustment pad 3, mandrel 4, valve 5 etc. before comprising, the preceding erection device of the subsidiary T type groove of back-up tong is driven on the top, centralizer 1 before comprising, spring 2 are pressed in by mandrel 4 on the step of preceding centralizer inside, the front end bolt, the other end uses adjustment pad 3 and mandrel 4 to compress, and T type structure on the preceding centralizer and the T type groove on the valve are slidingly connected.Preceding centralizer slides in the T of valve type groove when work, and T type groove links together preceding centralizer and valve by very little gap simultaneously, plays centralizing function.If distance is improper, then can the adjustment pad.Add a pair of T type groove at preceding centralizer and carrier valve thereof, then the displacement of Y, Z direction and external force all by the constraint of T type groove, make mandrel only be subjected to pulling force, and structure is more reasonable, has increased the reliability of back-up tong work, has prolonged the life-span of preceding centralizer.
Embodiment 2
The preceding erection device of the subsidiary T type groove of back-up tong is driven on the top, centralizer 6, spring 7, adjustment pad 8, mandrel 9, valve 10 before comprising, the preceding erection device of the subsidiary T type groove of back-up tong is driven on the top, comprise preceding centralizer, spring is pressed on the step of preceding centralizer inside by mandrel, front end bolt, the other end use adjustment pad and mandrel to compress, and two concave grooves to the symmetry of central opening on T type structure on the preceding centralizer and the valve are slidingly connected.
Claims (3)
1, the preceding erection device of the subsidiary T type groove of back-up tong is driven on the top, comprise preceding centralizer (1), spring (2) is pressed on the step of preceding centralizer inside by mandrel (4), the front end bolt, the other end uses adjustment pad (3) and mandrel (4) to compress, and it is characterized in that: T type structure and valve on the preceding centralizer are slidingly connected.
