Description

Embedded round nut lead screw pair dismounting device of electric valve
Technical Field
The utility model particularly relates to an embedded round nut lead screw pair assembly and disassembly tools of electric valve.
Background
Along with the continuous mining of mines, the underground mining gradually moves downwards according to production requirements, and at present, various types of valve electric devices are used in the underground of the mines; the pipeline of each water sump is provided with a sewage and sludge discharging electric gate valve. Because the water in the pit needs to be discharged to the ground surface, the valve electric device starts or stops to cause certain abrasion to a transmission system, and the screw rod valve core needs to be replaced after the valve is operated for a period of time. In the maintenance process of disassembling the screw rod and the circular nut of the valve electric device, the used tool adopts the blunt chisel to strike the circular nut, and the internal and external thread parts of the circular nut are damaged in different degrees due to the impact force received by the environmental limitation and the impact force received by the chisel hammer. Resulting in the inability to disassemble the lead screw and the round nut. Knocking and disassembling a nut for two hours at the longest time, and only replacing the whole valve electric device under the condition that the nut cannot be disassembled, thereby causing great influence on the safety production of a mining area.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an assembly and disassembly function integrated embedded round nut lead screw pair assembly and disassembly device.
In order to satisfy the above-mentioned purpose, the utility model discloses the technical scheme who takes does:
the utility model provides an embedded vice assembly and disassembly tools of round nut lead screw of electric valve, includes the handle, the one end of handle is provided with the handle jack catch, and the handle jack catch is provided with spacing recess with the junction of handle, the below of handle jack catch is provided with handle jack catch locating piece, handle jack catch upper end is equipped with the slot, be provided with the lead screw in the slot, the one end of lead screw is provided with movable jack catch, the below of activity jack catch is provided with movable jack catch fixed block, be provided with two excircle annular knurl rectangle nuts, two on the lead screw excircle annular knurl rectangle nut is located the slot both sides of handle jack catch, the excircle annular knurl rectangle nut of one side is located spacing recess.
Preferably, the movable clamping jaw fixing and handle clamping jaw positioning block is respectively installed below the movable clamping jaw and the handle clamping jaw through countersunk bolts.
Preferably, one end of the screw rod is provided with a threaded hole, and the movable clamping jaw is installed at one end of the screw rod through a bolt.
Preferably, the other end of the handle is provided with a hanging hole.
The utility model has the advantages that: the fixed clamping jaws are arranged on the handle, the movable clamping jaws are arranged, the lead screw and the bolt are arranged simultaneously to adjust the distance between the two clamping jaws to meet the dismounting and mounting work of the embedded round nut lead screw pair with various diameters, the phenomenon that the embedded round nut lead screw limited by environment cannot be dismounted and damaged when dismounted is avoided, the device is simple in structure and convenient to use, and the working efficiency of dismounting and mounting the embedded round nut lead screw pair is greatly improved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the handle of the present invention;
