Abstract

The invention discloses a maintenance method of an upright post guide sleeve and a disassembly and assembly tool thereof. The disassembly and assembly tool comprises two semi-circular wrenches, the two semi-circular wrenches are connected into a whole circular wrench, the guide sleeve can be unscrewed under the situation that an upright post is not separated from a top beam by descending, the guide sleeve can be directly repaired on the upright post and a sealing part can be replaced, so that the labor intensity is low and the working efficiency is high.

Description

The method for maintaining and the dismantling device thereof of guide pillar cover
Technical field
The present invention relates to a kind of maintenance technique of hydraulic support, relate in particular to a kind of method for maintaining and dismantling device thereof of guide pillar cover.
Background technology
When hydraulic support uses, phenomenon often having taken place to leak on the column, must change seal as early as possible or fairlead is repaired etc. under mine.
As shown in Figure 1, change seal or when fairlead repaired, must the fairlead on the column 13 be backed out, afterwards, change seal again or fairlead such as is repaired at work.
In the prior art, all being with the dismounting of monoblock type frock, specifically is that column 1 is fallen from back timber 2, is inserted in the monoblock type dismantling device from the upper end of column 1 and fairlead 3 is pulled down is keeped in repair, and sealing shroud is inserted in from the top of column again.Maintenance is taken off the monoblock type dismantling device after accomplishing again, column 1 is connected with back timber 2 again.
There is following shortcoming at least in above-mentioned prior art: labour intensity is big, inefficiency.
Summary of the invention
The purpose of this invention is to provide a kind of labour intensity is low, the guide pillar of high efficiency overlaps method for maintaining and dismantling device thereof.
The objective of the invention is to realize through following technical scheme:
The method for maintaining of guide pillar cover of the present invention does not fall under the situation of back timber at column, fairlead is backed out, and directly on column, repaired fairlead and change seal.
The dismantling device that is exclusively used in the method for maintaining of above-mentioned guide pillar cover of the present invention comprises the spanner of two semi-round ring shapes, and the spanner of two semi-round ring shapes is connected to the spanner of a whole ring form.
Technical scheme by the invention described above provides can be found out; The method for maintaining and the dismantling device thereof of guide pillar cover provided by the invention; Because through split type dismantling device; Do not fall under the situation of back timber at column, repair fairlead and the work of changing seal, low, the high efficiency of labour intensity.
Description of drawings
Fig. 1 is the partial structurtes sketch map of hydraulic support in the prior art;
The Facad structure sketch map of the dismantling device that Fig. 2 provides for the embodiment of the invention;
The side structure sketch map of the dismantling device that Fig. 3 provides for the embodiment of the invention.
Among the figure: 1, column, 2, back timber, 3, fairlead;
4,5, the semi-round ring shape spanner, 6, nut, 7, back-up ring, 8, bolt.
The specific embodiment
To combine accompanying drawing that the embodiment of the invention is done to describe in detail further below.
The method for maintaining of guide pillar cover of the present invention, its preferable specific embodiment is:
Do not fall under the situation of back timber at column, fairlead is backed out, and directly on column, repair fairlead and change seal.
The dismantling device that is exclusively used in the method for maintaining of above-mentioned guide pillar cover of the present invention, the specific embodiment that it is preferable such as Fig. 2, shown in Figure 3:
The spanner that comprises two semi-round ring shapes, the spanner of two semi-round ring shapes is connected to the spanner of a whole ring form.
The spanner of two semi-round ring shapes can be connected to the spanner of a whole ring form through bolt or bearing pin etc.When removing fairlead, can column and back timber separately just can directly be used, just connect and to have carried out dismounting work with bolt then.
The method for maintaining of split type dismantling device and fairlead is after down-hole application among the present invention, and not only dismounting is more convenient quick, and, greatly reducing working strength of workers, operating efficiency also doubles.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.

Claims (3)
