Description

Technical Field

[0001] This utility model relates to the field of coal mining machinery maintenance and installation tools, and in particular to a coal mine machinery drum disassembly and assembly device. Background Technology

[0002] In the maintenance of coal mining machinery and equipment, the mechanical drums of coal mining machines or conveyors need to be frequently disassembled and replaced due to wear.

[0003] Existing disassembly and assembly devices mostly use an arc-shaped clamping arm structure to clamp the surface of the drum, and move it by hydraulic or mechanical means. However, the arc-shaped clamping arm and the outer wall of the drum are in curved contact. During the translation process, the lateral pushing force will cause relative sliding between the outer wall of the drum and the clamping arm, which may lead to the drum accidentally falling off or colliding with the equipment, thus causing damage to the equipment. Therefore, this solution proposes a drum disassembly and assembly device for coal mine machinery to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figure 1 - Figure 4 The coal mine machinery drum disassembly and assembly device shown includes: Base 1; The disassembly and assembly component 2 includes a movable seat 206 set on the top of the base 1. The top of the movable seat 206 is provided with a support groove 205. The inner walls on both sides of the support groove 205 are symmetrically provided with through grooves 207. The top of the movable seat 206 is provided with a second clamp 204. A limiting member is provided on one side of the movable seat 206, and a push-out member is provided on the other side of the movable seat 206. The movable component 3 is located at the connection between the base 1 and the movable seat 206, and is used to move the position of the movable seat 206.

[0017] It should be noted that the support groove 205 is adapted to the roller, allowing the roller to enter the interior of the support groove 205. The through groove 207 is adapted to the shaft, allowing the shaft of the mechanical roller to pass through the through groove 207 and exit the support groove 205. The diameter of the through groove 207 is smaller than the diameter of the roller, preventing the roller from moving out of the support groove 205 through the through groove 207. Thus, when the roller moves horizontally, it is restricted by the inner walls on both sides of the support groove 205, preventing it from sliding inside the support groove 205. In use, the roller is placed inside the support groove 205, and its position is fixed by the second clamp 204. During use, the moving component 3 drives the moving seat 206 and the roller to move in different directions, realizing the disassembly and assembly of the roller and the shaft. The design of the support groove 205, the through groove 207, and the second clamp 204 prevents the roller from moving when its position is moved, thereby increasing the stability of the mechanical roller's disassembly and assembly.

[0018] Specifically, the limiting component includes a first upright plate 203 fixedly connected to the top of the base 1, a limiting groove 202 is provided on one side of the first upright plate 203, and a first clamp 201 is provided on the top of the first upright plate 203.

[0019] It should be noted that the limiting groove 202 is adapted to the shaft body, so that one end of the shaft body can be inserted into the interior of the limiting groove 202. The first clamp 201 is fixed by bolts at the top of the first upright plate 203, and by the limiting groove 202 and the first clamp 201.

[0020] Specifically, the push-out component includes a second upright plate 209 fixedly connected to the top of the base 1, and a pressing rod 208 fixedly connected to one side of the second upright plate 209.

[0021] It should be noted that the second upright plate 209 is fixed to the extrusion rod 208 and the base 1 by welding. During use, the shaft is extruded by the extrusion rod 208.

[0022] Furthermore, when it is necessary to disassemble the roller and the shaft, first move the movable seat 206 to fit against the first vertical plate 203, then insert the roller on the mechanical roller into the support groove 205, and insert one end of the shaft into the limiting groove 202. The first clamp 201 and the second clamp 204 are used to fix the position of one end of the shaft and the roller, respectively. At this time, one end of the shaft fits against one end of the pressing rod 208. Then, the movable assembly 3 drives the movable seat 206 to move towards one side of the second vertical plate 209. At this time, the shaft is restricted by the pressing rod 208 and cannot move, while the roller is moved by the movable seat 206. The roller is moved so that it is fitted onto the extrusion rod 208, thereby separating the roller from the shaft. When it is necessary to install the roller onto the shaft, the roller is first inserted into the support groove 205, and then the moving seat 206 is moved so that the roller is fitted onto the extrusion rod 208. Then, one end of the shaft is inserted into the limiting groove 202 so that one end of the shaft is in contact with the extrusion rod 208. Then, the first clamp 201 is used to fix one end of the shaft. Then, the moving seat 206 drives the roller to move to one side of the first vertical plate 203 and connects the roller and the shaft, thereby completing the installation of the shaft and the roller.

[0023] Specifically, the movable component 3 includes a sliding block 302 fixedly connected to the bottom of the movable base 206. A threaded rod 303 is threadedly connected to the middle of the sliding block 302. A drive motor 306 is fixedly connected to one end of the threaded rod 303. A sliding groove 305 is provided on the top of the base 1. The sliding block 302 is inserted into the interior of the sliding groove 305. The threaded rod 303 is inserted into the inner wall on one side of the sliding groove 305. A limiting rod 304 is inserted into the top of the sliding block 302. The limiting rod 304 is fixedly connected between the inner walls on both sides of the sliding groove 305. A fixed bearing 301 is sleeved on the other end of the threaded rod 303. The fixed bearing 301 is inserted into the inner wall on the other side of the sliding groove 305.

[0024] It should be noted that the drive motor 306 is an existing servo motor, used to move the threaded rod 303 at its output end. The drive motor 306 is fixed to one side of the base 1 by bolts. The fixed bearing 301 is an existing ball bearing, used to fix the position of one end of the threaded rod 303 without affecting its rotation. The limiting rod 304 is parallel to the threaded rod 303, and the threaded rod 303 and the limiting rod 304 are parallel to each other. The sliding block 302 is restricted by the two fixed and parallel rods, which restricts the movement direction of the sliding block 302 and prevents it from rotating. When it is necessary to move the moving seat 206, the drive motor 306 drives the threaded rod 303 at its output end to rotate, and the rotating threaded rod 303 drives the threaded and non-rotating sliding block 302 to move, and the moving sliding block 302 drives the moving seat 206 to move.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
