Description

Mining hydraulic coupler bearing maintenance dismounting device

Technical Field

The utility model relates to a maintenance and disassembly device for a mining hydraulic coupler bearing, and belongs to the technical field of maintenance of mining hydraulic coupler bearings.

Background

China is a large country for coal production in the world, and the coal yield occupies the first place in the world. The coal exploitation mode in China is mainly underground exploitation, a large amount of electromechanical transportation equipment is needed for coal production, and along with the large-scale development of coal mines, the volume and the power of underground equipment are large. The fluid coupling is a non-rigid coupling using liquid as working medium, also called fluid coupling, and mainly consists of pump wheel, turbine, shell body and bearing. The hydraulic coupler is a large power transmission device commonly used in underground coal mines, is mainly used for connection between a motor and a speed reducer, can effectively improve the starting performance of the motor, and plays a role in overload protection. In order to save the cost and reduce the consumption, the old and useless, the mine needs to repair the damaged hydraulic coupler to the ground, and the bearing of the mine is often damaged and needs to be removed from the shaft for replacement due to the severe underground environment of the mine. At present, a bearing which is rusted and difficult to detach can be removed only by hard prying and beating with a flat screwdriver or cutting the bearing into two halves by a gas cutting method, so that the shaft of the hydraulic coupler can be damaged sometimes by the operation, and the whole hydraulic coupler is scrapped. In addition, the whole maintenance process is longer, the efficiency is lower, and time and labor are wasted.

Disclosure of Invention

The utility model aims to provide a mining hydraulic coupler bearing maintenance and disassembly device which is convenient to operate, time-saving, labor-saving and high in maintenance efficiency.

In order to achieve the above object, the present utility model includes: the device comprises a bracket, a platform, semicircular slips, stand columns, a cross beam and a jack, wherein the platform is supported by the bracket connection, the stand columns are respectively fixedly arranged at two sides of the platform, the cross beam is arranged at the upper end of the stand columns, the jack is fixedly connected to the lower part of the middle of the cross beam, the piston head of the jack faces downwards, a round hole is formed in the middle of the platform, and two semicircular slips matched with each other are arranged in the round hole.

The semicircular slips are provided with a shaft penetrating hole, a bearing clamping seat and a bearing edge.

When the bearing is used, one semicircular slip is placed on one side of a round hole of the platform, then the bearing with the shaft is placed in the bearing clamping seat to enable the shaft end to face downwards, then the other semicircular slip is placed in the round hole of the platform, the bearing edge clamps the surface of the platform, the whole bearing is clamped in the round bearing clamping seat formed by the two semicircular slips in a surrounding mode, the function of supporting the semicircular slips and the bearing by the platform is achieved, finally the jack is operated, the downward force of the piston head of the jack is enabled to act on the shaft in the bearing slowly, and the bearing is ejected out from the inside of the bearing by means of the larger force of the jack, so that the dismounting work of the bearing is completed. The whole disassembly and maintenance process only needs one person to operate, and the replacement of the bearing difficult to disassemble can be conveniently completed. Has the characteristics of simple operation, convenient use, time and labor saving, high working efficiency and the like.

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a schematic top view of a semicircular slip and platform.

The reference numerals are explained as follows:

1-a bracket; 2-a platform; 3-semicircular slips; 4-piston heads; 5-stand columns; 6, a cross beam; 7-jack; 8-passing through the shaft hole; 9-a bearing clamping seat; 10-bearing edges; 11-round holes.

Description of the embodiments

The utility model is described in further detail below with reference to the accompanying drawings.

As can be seen from fig. 1 and 2, the present utility model includes: the device comprises a bracket 1, a platform 2, semicircular slips 3, an upright post 5, a cross beam 6 and a jack 7. The platform 2 is connected and supported by the support 1, the platform adopts steel plate processing to form a rectangular structure, four corners below the platform are respectively supported by the support connection, and the support adopts round steel processing and manufacturing and is welded with the platform together so as to ensure the firm stability of the platform. Two sides of the platform are respectively and fixedly provided with a stand column 5, the upper end of the stand column is provided with a cross beam 6, the lower part in the middle of the cross beam is fixedly connected with a jack 7, and the piston head 4 of the jack faces downwards. The upright post is manufactured by processing round steel, and the height and the strength of the upright post can ensure the working requirement of the jack; the beam is made of steel, and the length and the strength of the beam can ensure the working requirement of the jack. A round hole 11 is formed in the middle of the platform, two matched semicircular slips 3 are placed in the round hole, and a through-shaft hole 8, a bearing clamping seat 9 and a bearing edge 10 are arranged on the semicircular slips. The semicircular slips 3 are manufactured by processing steel plates, and the strength of the semicircular slips can ensure the working requirement of the jack. The center of the piston head of the jack is matched with the center of the semicircular slip, the size of the through shaft hole 8 of the semicircular slip and the size of the bearing clamping seat 9 are matched with the size of the shaft and the bearing of the mining hydraulic coupler, so that the piston head can be accurately propped against the shaft in the bearing to finish the disassembly work during the work. When the semi-circular slip is actually and specifically used, semi-circular slips with different inner diameter specifications can be manufactured to meet the disassembly requirements of different bearings on site.

In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be either a fixed connection or a removable connection, for example; the specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
