Abstract
Description
Technical Field:
[0001] The utility model relates to the technical field of experimental auxiliary equipment, and particularly relates to a roller disassembly tool for a belt conveyor. Background Art:
[0002] In the conveying process of coal mines, conveyor belts supported by upper and lower rollers are commonly used. With the increase in the coal transportation volume of coal mines, problems such as conveyor belt wear caused by roller damage, conveyor belt deviation from the track, and coal scattering have become increasingly serious. Therefore, it is particularly important to conduct daily inspections on the rollers and decide whether to replace them.
[0003] However, with the gradual increase in the number of rollers to be replaced, the labor intensity of workers has increased significantly. In addition, the conveyor belt itself is not light, and the rollers also have a certain weight. When replacing, usually multiple people need to cooperate and use an iron rod to pry to complete the replacement work. This not only takes time and effort, but also has low work efficiency and high safety risks. Content of the Utility Model:
[0004] The purpose of the utility model is to provide a roller disassembly tool for a belt conveyor to solve the problems raised in the above background art.
[0005] The utility model is implemented by the following technical solutions:
[0006] A roller disassembly tool for a belt conveyor includes an angle steel, a lower screw rod, an adjusting member, an upper screw rod, an iron hook, an eccentric shaft, a limiting circular plate, and a steel pipe; the middle of the protruding edge of the angle steel is fixed to the bottom end of the lower screw rod, the top of the lower screw rod is threadedly connected to the bottom end of the adjusting member, the top of the adjusting member is threadedly connected to the bottom of the upper screw rod, the top of the upper screw rod is hinged to the middle of the iron hook, an eccentric shaft is fixed to one end of the iron hook away from the hook part, a limiting circular plate is rotatably arranged on the eccentric shaft, a steel pipe is sleeved on the iron hook, when the limiting circular plate and the steel pipe are not coaxial, the steel pipe is located between the upper screw rod and the limiting circular plate and cannot slide out of the iron hook; when the limiting circular plate and the steel pipe are coaxial, the steel pipe can slide out of the iron hook.
[0007] Preferably, the overall structure of the adjusting member is in the shape of a "day", threaded holes adapted to the lower screw rod and the upper screw rod are opened at the upper and lower ends of the adjusting member, and a through hole is opened in the middle of the adjusting member.
[0008] Preferably, the thread directions of the lower screw rod and the upper screw rod are opposite.
[0009] Preferably, an anti-slip sleeve is fixedly sleeved on the iron hook, the anti-slip sleeve is located between the upper screw rod and the hook part of the iron hook, and the anti-slip sleeve is made of rubber material.
[0010] Preferably, the inner diameter of the steel pipe and the outer diameter of the iron hook are equal.
[0011] Preferably, the top of the upper screw and the middle of the iron hook can be fixedly connected.
[0012] The advantages of this utility model are: simple and quick operation. First, hang the iron hook on the belt, then clamp the concave side of the angle steel on the frame, take out the steel pipe and insert it into the through hole. By rotating the steel pipe, the adjusting part is rotated, gradually increasing the distance between the upper screw and the lower screw, so that the belt is separated from the idler roller, and the idler roller is quickly replaced. This reduces the number of maintenance personnel and physical labor consumption, and improves work efficiency. Attached image description:

[0019] 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.
[0020] Please see Figure 1-5 This utility model provides a technical solution for a tool for disassembling idlers on a belt conveyor:
[0021] Example 1
[0022] Please refer to Figures 1-3. A tool for removing idlers for a belt conveyor includes an angle steel 1, a lower screw 2, an adjusting component 3, an upper screw 4, an iron hook 5, an eccentric shaft 6, a limiting circular plate 7, and a steel pipe 8.
[0023] The middle of the protruding edge of the angle steel 1 is fixed to the bottom end of the lower screw rod 2. The overall structure of the adjusting member 3 is in the shape of a Chinese character 'Ri' (日). Threaded holes adapted to the lower screw rod 2 and the upper screw rod 4 are provided at the upper and lower ends of the adjusting member 3, and a through hole 3.1 is provided in the middle of the adjusting member 3. The top of the lower screw rod 2 is threadedly connected to the bottom end of the adjusting member 3, the top end of the adjusting member 3 is threadedly connected to the bottom of the upper screw rod 4, and the thread directions of the lower screw rod 2 and the upper screw rod 4 are opposite. The top of the upper screw rod 4 is hinged to the middle of the iron hook 5. The outer diameter of the steel pipe 8 is smaller than the diameter of the through hole 3.1, and the steel pipe 8 is used to be inserted into the through hole 3.1 for rotating the adjusting member 3 to control the distance between the upper screw rod 4 and the lower screw rod 2.
[0024] To facilitate the integrity of the tool and avoid the loss of the steel pipe 8, a steel pipe 8 is sleeved on the iron hook 5. The inner diameter of the steel pipe 8 is equal to the outer diameter of the iron hook 5. An eccentric shaft 6 is fixed at one end of the iron hook 5 away from the hook part. A limiting circular plate 7 is rotatably arranged on the eccentric shaft 6. When the limiting circular plate 7 is not coaxial with the steel pipe 8, the steel pipe 8 is located between the upper screw rod 4 and the limiting circular plate 7 and cannot slide out from the iron hook 5; when the limiting circular plate 7 is coaxial with the steel pipe 8, the steel pipe 8 can slide out from the iron hook 5. A non-slip sleeve 9 is fixedly sleeved on the iron hook 5, and the non-slip sleeve 9 is located between the upper screw rod 4 and the hook part of the iron hook 5. The non-slip sleeve 9 is made of rubber material.
[0025] Please refer to Figure 5 As shown in the figure, the working principle is as follows: First, hook the hook part of the iron hook 5 on the belt 12, make the non-slip sleeve 9 be placed on the lower surface of the belt 12, then clamp the concave surface of the angle steel 1 of the tool on the frame 10 of the belt conveyor, rotate the limiting circular plate 7 to make it coaxial with the steel pipe 8, slide the steel pipe 8 out from the iron hook 5 and insert it into the through hole 3.1, and then pull the steel pipe 8 to rotate the adjusting member 3, so that the distance between the upper screw rod 4 and the lower screw rod 2 gradually increases, making the belt 12 separate from the idler 11, and replace the idler.
[0026] Finally, pull the steel pipe 8 to rotate the adjusting member 3, so that the distance between the upper screw rod 4 and the lower screw rod 2 gradually decreases, making the belt 12 fit with the idler 11 again.
[0027] Embodiment 2
[0028] Please refer to Figure 4 and Figure 3 As shown in the figure, compared with Embodiment 1, the overall structures of the two are basically the same, and the difference between the two is that the top of the upper screw rod 4 is fixedly connected to the middle of the iron hook 5.
[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
