Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a roller disassembly device. Background Art

[0002] During the long-term use of the belt conveyor, the roller will often wear and accumulate dirt due to repeated operation and material friction. This wear not only affects the performance of the roller, but also causes damage or aging of certain components (such as bearings, belts and seals). As the use time increases, these problems will gradually worsen, affecting the efficiency and stability of the entire conveying system.

[0003] When the production line or equipment design changes, it is usually necessary to adjust the position or configuration of the roller. This process often requires the roller to be disassembled. In actual operation, disassembly is generally done manually. Since the roller is usually heavy, improper handling may cause injuries, especially in the absence of appropriate auxiliary tools or insufficient manpower, which significantly increases safety risks.

[0004] In addition, improper disassembly also leads to wear and damage to the surface of the roller. For example, if the operator uses improper tools or applies uneven force, it will cause scratches or dents on the surface of the roller. This will not only affect the function of the roller, but also cause greater wear on the belt during subsequent use, shortening the service life of the belt and increasing the cost of subsequent replacement and maintenance. At the same time, when frequent adjustments or replacements of equipment are required, it will cause the production line to stagnate, affecting overall production efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a roller disassembly device to solve the problems of personal injury caused by manual disassembly, low disassembly efficiency, and wear and damage to the roller surface caused by improper disassembly.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller disassembly device, comprising a base, a first hydraulic cylinder, a support platform, and a lifting device, wherein the four corners of the top of the base are respectively connected to guide rods, the middle of the top of the base is connected to the first hydraulic cylinder, the top of the piston rod of the first hydraulic cylinder is connected to the support platform, a positioning hole is opened on the support platform corresponding to the guide rod, a guide rod is arranged in the positioning hole, and the support platform is slidably matched with the guide rod, and the lifting devices are symmetrically connected to the left and right sides of the support platform.

[0007] The lifting device includes a support frame, a sliding rod, a connecting rod, and a lifting block. The support frame is connected to the supporting platform and is concavely arranged, with the concave end facing the top of the supporting platform. A second hydraulic cylinder is provided in the concave end. A sliding groove is provided in the middle of the top of the support frame, and a fixed rod is connected to the left and right sides of the sliding groove respectively. Two sliding rods are provided in the sliding groove, and the two sliding rods are slidably matched with the support frame, and the bottom ends are connected through a fixed plate. The bottom end of the fixed plate is connected to the top of the piston rod of the second hydraulic cylinder. The top ends of the sliding rods are respectively hinged with connecting rods, and the other ends of the connecting rods are respectively hinged to the lifting blocks, and the end of the lifting block away from the connecting rod is hinged to the fixed rod, and the lifting block is in contact with the roller.

[0008] Preferably, the contact end of the lifting block and the roller is arranged in an arc shape, and the arc end is fitted to the outer circumference of the roller.

[0009] Preferably, the first hydraulic cylinder is connected to the hydraulic pump via a pipeline, and a first stop valve is provided on the pipeline.

[0010] Preferably, the second hydraulic cylinder is connected to the hydraulic pump via a pipeline, and a second stop valve is provided on the pipeline.

[0011] Preferably, the four corners of the bottom end of the base are respectively connected with moving wheels.

[0012] Preferably, a push rod is further included, which is connected to the base and is used to manually push the base.

[0014] Preferably, the size of the fixing plate corresponds to the setting of the sliding groove, and the fixing plate is fitted with the inner wall of the sliding groove in its circumference and is slidably fitted in the sliding groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] By setting up a mobile base, when disassembling the roller, first move the base to the bottom of the roller to be disassembled, then start the first hydraulic cylinder, the piston rod will rise accordingly, and lift the support platform to a suitable height. When the support platform is stable, the lifting devices on both sides will respectively support the two ends of the roller to ensure that it remains stable during the disassembly process. When handling rollers of different diameters, it is necessary to start the second hydraulic cylinder, which will lift the fixed plate and drive the slide rod to move upward at the same time. The slide rod changes the angle of the lifting block through the connecting rod to adapt to the support requirements of rollers of different sizes. This design can effectively adjust the lifting block to better match the shape of the roller. To improve the safety and efficiency of disassembly, when the roller is lifted into place, continue to operate the first hydraulic cylinder, the piston rod will continue to rise, further raising the support platform away from the disassembly position. At this time, the piston rod of the first hydraulic cylinder retracts, safely lowering the roller to complete the disassembly process. The application of this hydraulic system not only improves the safety and efficiency of disassembly, but also effectively reduces the risks brought by manual operation. In addition, the design of the mobile base also enables flexible adjustment when disassembling rollers of different types and specifications to adapt to a variety of working environments and needs. The implementation of this system will greatly improve the operating efficiency of the production line and reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
