Abstract

The utility model relates to a hydraulic support stand column guide sleeve dismounting tool, belonging to the technical field of hydraulic supports; the problem that a disassembling tool is not available when the guide sleeve of the upright post of the hydraulic support needs to be disassembled and assembled underground at present is solved; the handle is provided with a circular through hole in the middle and holding parts on two sides; the check ring is of a circular plate-shaped structure, a plurality of threaded holes are uniformly distributed in the circumferential direction of the axis of the check ring, and the threaded holes are through holes; handle and retaining ring use the central line of round hole respectively as the benchmark mutually to laminate and fixed connection, tightly push up the uide bushing through the bolt, pull the handle and just can carry out the dismouting to the uide bushing, need not supplementary supporting implementation such as power, pump station, and operating personnel is bare-handed can accomplish the dismouting to the stand uide bushing, and the flexibility is higher.

Description

Hydraulic support stand uide bushing assembly and disassembly tools

Technical Field

The utility model belongs to the technical field of hydraulic support, concretely relates to hydraulic support stand uide bushing assembly and disassembly tools.

Background

The hydraulic support upright column mainly comprises a cylinder body assembly, a plunger assembly and a guide sleeve assembly, wherein the guide sleeve is matched with the outer cylinder body through threads, and the guide sleeve mainly plays a role in guiding and sealing when the plunger moves.

At present, most of the commercial hydraulic support upright post guide sleeve dismounting equipment adopts electric or hydraulic equipment, although the equipment can quickly dismount the guide sleeve, the equipment has larger volume, needs supporting facilities such as a power supply or a pump station and is inconvenient to use underground; secondly, its manufacturing cost is relatively high. When the conditions such as guide sleeve leakage and the like occur underground on the hydraulic support stand column, the stand column sealing ring is preliminarily judged to be damaged or aged, the sealing ring needs to be replaced after the guide sleeve is disassembled on the stand column, the stand column has to be disassembled due to the fact that the guide sleeve cannot be disassembled underground, and the stand column is conveyed to the underground to be disassembled and assembled and replaced, so that the coal mining progress is influenced.

Disclosure of Invention

The utility model overcomes the defects of the prior art and provides a hydraulic support upright post guide sleeve dismounting tool; the problem of present need lack assembly and disassembly tools to hydraulic support stand uide bushing dismouting in the pit is solved.

In order to achieve the above purpose, the present invention is achieved by the following technical solutions.

A hydraulic support upright post guide sleeve dismounting tool comprises a handle, a retainer ring and a bolt, wherein the middle part of the handle is a circular through hole, and two sides of the handle are provided with holding parts; the check ring is of a circular plate-shaped structure, a plurality of threaded holes are uniformly distributed in the circumferential direction of the check ring relative to the axis, and the threaded holes are through holes; the handle and the retainer ring are respectively attached and fixedly connected by taking the center line of the circular hole as a reference.

Further, the holding part is of a cuboid structure.

Further, the number of the threaded holes is 6-8.

Further, the handle and the retainer ring do not have a connecting structure at the threaded hole.

The utility model discloses produced beneficial effect for prior art does:

1. the disassembling tool consists of a handle, a check ring and a bolt, and compared with the prior art, the tool has the advantages of simple structure, small volume, low manufacturing cost and the like;

2. the tool is convenient to carry, and can be brought into a well to disassemble, assemble and maintain the upright post guide sleeve;

3. this instrument need not supplementary supporting implementation such as power, pump station, and operating personnel is bare-handed can accomplish the dismouting to the stand uide bushing, and the flexibility is higher.

FIG. 1 is a schematic view of the overall structure of the device of the present invention;

FIG. 2 is a schematic view of the handle of the device of the present invention;

FIG. 3 is a schematic structural view of the retainer ring of the device of the present invention;

FIG. 4 is a schematic structural view of the device of the present invention when the column guide sleeve is disassembled;

in the figure, 1 is a handle, 2 is a retainer ring, 3 is a bolt, 4 is an upright post and 5 is a guide sleeve.

Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1-4, the utility model provides a hydraulic support upright post guide sleeve dismounting tool, which comprises a handle 1, a retainer ring 2 and a bolt 3, wherein the handle 1 adopts a structure that the middle part is a circular through hole and the two ends are cuboids; the retainer ring 2 is of a circular plate-shaped structure, 6-8 threaded holes are uniformly distributed in the periphery of the axis of the retainer ring 2, and the threaded holes are designed to penetrate through; then the connection is carried out in a welding mode, and the threaded hole of the retainer ring 2 is not welded.

The utility model discloses a principle and application method: the side end face of the dismounting tool provided with the check ring 2 faces the stand column 4, all the bolts 3 are outwards adjusted, the head of each bolt 3 is not exposed to the inner hole area of the corresponding check ring 2, the dismounting tool is sleeved in from one end of a column head of the stand column 4, one side end face, far away from the handle, of each check ring 2 is attached to the upper end face of the stand column guide sleeve, the check rings 2 and the stand column 4 guide sleeves 5 are on the same horizontal plane, the positions of the bolts 3 are aligned with the tooth mouth positions of the guide sleeves 5, and the bolts 3 are screwed down until all the bolts 3 all prop against the guide sleeves 5. At the moment, an operator can pull the two ends of the handle 1 to detach the guide sleeve 5 of the stand column 4, the sealing element is replaced, and after the replacement is completed, the guide sleeve 5 is installed in place by adopting the method, so that the whole dismounting process of the guide sleeve 5 of the stand column 4 is completed.

Through using the utility model provides an assembly and disassembly tools when carrying out dismouting, maintenance to the stand uide bushing in the pit, need not supplementary supporting implementation such as power, pump station, and operating personnel is bare-handed can accomplish the dismouting to the stand uide bushing, and the flexibility is higher.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
