Abstract

A mounting and dismounting tool for a hydraulic oil cylinder locking cap comprises a main body and clamping blocks, wherein two sides of the main body are provided with clamping handles; a round hole is formed in the middle of the main body; the clamping blocks are fixed on the main body; the clamping blocks extend into the round hole in a protruding way; the protruding length of each clamping block is 4-8 mm; a plurality of clamping blocks are evenly distributed in the round hole by taking the center of the round hole as the center; the locking cap can be inserted in the round hole; the clamping blocks are clamped in a groove of the locking cap; force applying bars can be arranged on the clamping handles in a sleeving manner; the locking cap can be driven to rotate by rotating the clamping handles, so that the locking cap can be dismounted. According to the mounting and dismounting tool, the locking cap can be mounted conveniently and fast, the labor intensity of workers can be reduced, the working efficiency is high, the locking can not be damaged, the safety is good, and obvious economic benefits and social benefits can be realized.

Description

Hydraulic jack locking cap dismantling device

Technical field

The utility model be the oil field at the maintenance frock of the large-scale wheeled jack lift of usefulness, be a kind of hydraulic jack locking cap dismantling device.

Background technology

The oil drilling resettlement, derrick installation needs large-scale wheeled jack lift, because work under bad environment, Leakage often appears in the oil cylinder of crane hydraulic system, needing often to change oil sealing could work, oil sealing is compressed by locking cap, change oil sealing, must dismantle locking cap, locking cap is connected with the head threads of oil cylinder, and several equally distributed grooves are arranged on its outer wall, hook-headed wrench when being used for the dismounting locking cap, is installed groove, because the locking cap size is large, hook-headed wrench holds can't stand excessive torsion, is out of shape easily when using strength excessive to fracture, when dismantling with pipe wrench, can occur skidding, damage the problem of locking cap, owing to can not dismantle smoothly locking cap with hook-headed wrench and pipe wrench, service worker often adopts chock and sledgehammer to carry out the destructiveness dismounting, service worker labour intensity is large, and maintenance time is long, fragile locking cap, increase maintenance cost, when carrying out the destructiveness dismounting with sledgehammer, also have potential safety hazard.

Summary of the invention

The purpose of this utility model is a kind of hydraulic jack locking cap dismantling device of design, can dismantle easily and efficiently the hydraulic jack locking cap, improves repair quality, alleviates labor strength, increases work efficiency.

The purpose of this utility model is achieved in that and comprises main body, fixture block, and there is the card handle main body both sides, and there is circular hole inside, fixture block is fixed on the main body, fixture block protrudes in the circular hole, and the length of protrusion is 4-8mm, and several fixture blocks are evenly distributed in the circular hole as the center of circle take the center of circle of circular hole.

The beneficial effects of the utility model are: circular hole can be enclosed within on the locking cap, fixture block is stuck in the groove of locking cap, can be set with afterburning thick stick on the card handle, the revotating card handle just can drive the locking cap rotation, and locking cap is disassembled, the utility model dismounting locking cap is convenient, fast, operator's labour intensity is low, and high efficiency can not destroyed locking cap, security is good, has significant economic benefit and social benefit.

Description of drawings

Fig. 1 is the installation diagram of the utility model embodiment.

The specific embodiment

Below in conjunction with Fig. 1 the utility model embodiment is described.

As seen from the figure, embodiment of the present utility model comprises main body 1, fixture block 2, there is card handle 4 main body 1 both sides, there is circular hole 3 inside, fixture block 2 is fixed on the main body 1 and (the position processing mounting groove of fixture block 2 is being installed, with fixture block 2 put into after and main body integrally welded), fixture block 2 protrudes into 3 li of circular holes, the length of protruding is 4-8mm, the length of protruding is less than the degree of depth of locking cap upper groove, and several fixture blocks 2 are evenly distributed on 3 li of circular holes take the center of circle of circular hole 3 as the center of circle, can be fine together supporting with locking cap, the utility model is linked together as spline joint with locking cap, reach the effect of transmitting torque.

Claims
