Abstract
The utility model relates to a locking mechanism for a reversing valve, which comprises a handle, a locking bolt and a fixed seat, wherein an internal thread through hole which is matched with the locking bolt is arranged in the center of the fixed seat; the locking bolt is connected with the fixed seat in a matching way; and the handle is welded on the locking bolt. Compared with the prior art, the locking mechanism has the beneficial effects that: (1) as the device employs the locking bolt to directly press a reversing pin shaft with security and reliability, an accident that a serviceman is injured once the reversing valve rotates is effectively prevented; (2) the device employs the way that the handle is welded on the locking bolt, the locking bolt can be screwed or loosened by directly rotating the handle in operation, therefore, the operation is convenient and flexible for an operator; and (3) the device is simple in structure, convenient in installation, rational in design and low in cost.
Description
Technical field
The utility model relates to a kind of locking device, particularly a kind of selector valve locking mechanism.
Background technique
In petroleum drilling operation, hydraulic tongs is a drilling and repairing well rig tool commonly used, but when using hydraulic tongs to keep in repair, makes the selector valve switching-over if the scene has the people to bump selector valve accidentally, will damage the maintenance man.And existing hydraulic power plier selector valve is for above-mentioned condition, do not have the special structure of its motion being made restriction.
Therefore, under the prerequisite of being convenient to operate and not influencing the hydraulic tongs proper functioning, need a kind of simple in structurely, easy to use can make the hydraulic tongs maintenance operation time, safe and reliable device is locked selector valve.
Summary of the invention
The purpose of the utility model provides a kind of selector valve locking mechanism, and this apparatus structure is simple, reasonable in design, easy to use, and is safe and reliable.
For realizing above-mentioned purpose, the utility model adopts following technological scheme to realize:
A kind of selector valve locking mechanism comprises handle, lock bolt, fixed base, and described fixed base center is provided with the internal thread through hole that matches with lock bolt, and lock bolt and fixed base are connected, and described handle is welded on the lock bolt.
Compared with prior art, the beneficial effect of the utility model is: 1) this device adopts lock bolt bearing pin that directly will commutate to compress, and is safe and reliable, effectively prevented the generation of the rotation of selector valve to maintenance man's injury accident; 2) this device adopts handle to be welded on the lock bolt, and direct rotatable handle just can be tightened or loosening lock bolt during operation, and it is convenient, flexible that the operator is operated; 3) this apparatus structure is simple, easy for installation, reasonable in design, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-switching-over valve body 2-switching-over bearing pin 3-handle 4-lock bolt 5-fixed base
Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1; A kind of selector valve locking mechanism; Comprise handle 3, lock bolt 4, fixed base 5, fixed base 5 centers are provided with the internal thread through hole that matches with lock bolt 4, and lock bolt 4 is connected with fixed base 5; Handle 3 is welded on the lock bolt 4, and fixed base 5 is welded on the vertical direction of switching-over valve body 1 surface switching-over bearing pin 2.
When this device uses; At first fixed base 5 is welded on switching-over valve body 1 surface, and the vertical direction of switching-over bearing pin 2, the lock bolt 4 that will be welded with handle 3 again screws in the through hole of fixed base 5; When the operator uses hydraulic tongs to carry out work; Can turn handle 3, tighten lock bolt 4 and be pressed on the surface of switching-over bearing pin 2 until lock bolt 4, switching-over bearing pin 2 can not be rotated; When the switching-over bearing pin that needs selector valve 2 rotates, but also turn handle 3, lock bolt 4 is loosening, and at this moment switching-over bearing pin 2 surfaces will be left in lock bolt 4 bottoms, and switching-over bearing pin 2 is work capable of reversing.So just realized locking to selector valve, and then unexpected rotation and the accident that causes of selector valve when having prevented that the operator from keeping in repair.
Claims (1)
1. selector valve locking mechanism; It is characterized in that, comprise handle, lock bolt, fixed base, described fixed base center is provided with the internal thread through hole that matches with lock bolt; Lock bolt and fixed base are connected, and described handle is welded on the lock bolt.
