CN102748044A - Method for assembling single hydraulic prop - Google Patents

Abstract

The invention discloses a method for assembling a single hydraulic prop. The method comprises the following steps of: A, cleaning each component of the single hydraulic prop with pressure oil; B, arranging a dust-proof ring, a sealing ring and a retainer ring on a handle valve body, wherein the retainer ring is required to be arranged on a low-pressure side; C, loading a guide ring into a plunger; D, loading the plunger into an oil cylinder, arranging a handle body, and inserting a connecting steel wire; E, loading a sealing cover assembly into the plunger till a sealing cover is flush with the end part of the plunger; F, loading a top cover into the plunger and connecting through an elastic cylindrical pin; G, hanging a return spring, and loading a base and a connecting steel wire; H, after assembly, horizontally placing the prop, pulling the plunger out of the oil cylinder with the hand, verifying whether the plunger can retract automatically and flexibly under the action of the return spring, otherwise, disassembling for checking; I, arranging a three-function valve; and J, after the single prop is assembled, testing with water, disassembling the sealing cover for draining water completely, and returning to the steps E to I. According to the method, the product quality is improved, and delivery cost is reduced.

Description

A kind of hydraulic prop assembly method

Technical field

The present invention relates to a kind of hydraulic prop assembly method.

Background technology

Hydraulic prop is a kind of supporting equipment of new environment-friendly type, both can adopt face timbering top board and fully-mechanized mining working supporting termination with big gun with the supporting high-grade conventional mining that is used for of metal hinge top beam, also can do a post or other temporary supporting usefulness separately.

Individual prop needs the sealing performance with the water test pillar after assembling is accomplished, pack then, has water to increase the weight of delivering in the cylinder, the long product quality that also influences of time.

Summary of the invention

To the problem that above-mentioned prior art exists, the present invention provides a kind of hydraulic prop assembly method, improves the quality of products, and reduces the cost of delivery.

To achieve these goals, the technical scheme of the present invention's employing is: a kind of hydraulic prop assembly method comprises the steps:

A. clean each parts of hydraulic prop with pressure oil;

B. on the handgrip valve body, adorn dust ring, sealing ring, back-up ring, back-up ring position and should be contained in low-pressure side;

C. with the guide ring post alive of packing into;

D. the post of will the living oil cylinder of packing into installs handlebody, puts on the connection steel wire;

E. the seal cover assembly is packed in the post alive, makes seal cover concordant with the column end of living:

F. with the top cover post alive of packing into, connect with elastic cylindrical pin;

G. hang up properly back-moving spring, load onto base and be connected steel wire;

H. after the assembled, the horizontal positioned pillar is extracted in oil cylinder with the hand post of will living, the post of living should be under action of reset spring retraction flexibly automatically, otherwise answer overhaul;

I. install triple-use valve;

After comprising that also the assembling of step J. individual prop is accomplished, use water test, the seal cover of dismantling is then put water totally, and returns repeating step E to I.

The invention has the beneficial effects as follows: after the individual prop assembling is accomplished, use water test, dismantle seal cover then and put water totally, ressemble new seal cover,, also reduced the cost of delivery even long-time placement the after packing is accomplished can not influence product quality yet.

The specific embodiment

Be described further in the face of the present invention down.

A kind of hydraulic prop assembly method comprises the steps:

A. clean each parts of hydraulic prop with pressure oil;

B. on the handgrip valve body, adorn dust ring, sealing ring, back-up ring, back-up ring position and should be contained in low-pressure side;

C. with the guide ring post alive of packing into;

D. the post of will the living oil cylinder of packing into installs handlebody, puts on the connection steel wire;

E. the seal cover assembly is packed in the post alive, makes seal cover concordant with the column end of living:

F. with the top cover post alive of packing into, connect with elastic cylindrical pin;

G. hang up properly back-moving spring, load onto base and be connected steel wire;

H. after the assembled, the horizontal positioned pillar is extracted in oil cylinder with the hand post of will living, the post of living should be under action of reset spring retraction flexibly automatically, otherwise answer overhaul;

I. install triple-use valve;

After comprising that also the assembling of step J. individual prop is accomplished, use water test, the seal cover of dismantling is then put water totally, and returns repeating step E to I.

After individual prop assembling of the present invention is accomplished, use water test, dismantle seal cover then and put water totally, ressemble new seal cover,, also reduced the cost of delivery even long-time placement the after packing is accomplished can not influence product quality yet.
