Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for the maintenance of belt conveyor equipment, and in particular to a quick replacement tool for belt conveyor rollers. Background Technology

[0002] Belt conveyors, as key equipment for continuous material transport in industrial production, are widely used in mining, port loading and unloading, power plant fuel transportation, and chemical raw material transportation due to their advantages such as large conveying capacity, high efficiency, and stable operation. As the core transmission component of belt conveyors, rollers play a crucial role in driving the conveyor belt and changing its direction. Operating under harsh conditions of heavy load, high friction, and strong impact for extended periods, they are prone to wear, deformation, and bearing damage, leading to decreased conveying efficiency and even equipment downtime. Statistics show that in large mining enterprises, belt conveyor rollers are replaced an average of 3-5 times per year, with each replacement typically taking 4-6 hours, severely impacting production continuity.

[0003] When existing technical solutions are used,

[0004] (1) The manual screw clamping structure has a complicated adjustment process, requiring the operator to rotate the screw multiple times to fix the roller. It is also difficult to adapt to rollers with different diameters and surface shapes. For rollers with diameter deviations, the clamping stability drops significantly, resulting in low replacement efficiency.

[0005] (2) The overall device is not equipped with a shock-absorbing and buffering structure. During the movement, the vibration caused by uneven ground will be transmitted to the inside of the equipment, which will aggravate the wear of parts and shorten the service life of the equipment. The lack of precise guidance and limiting devices makes it easy to sway left and right during the lifting process, which may cause it to roll down.

[0006] To address the aforementioned problems, this utility model provides a quick-change tool for belt conveyor rollers. Utility Model Content

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a quick-change tool for belt conveyor rollers, comprising a load-bearing platform, a clamping and fixing mechanism, a lifting and adjusting mechanism, and a stabilizing and safety mechanism. The clamping and fixing mechanism is fixedly connected to the top of the load-bearing platform, the lifting and adjusting mechanism is threadedly connected to the bottom of the load-bearing platform, and the stabilizing and safety mechanism is fixedly connected to the bottom of the lifting and adjusting mechanism. The clamping and fixing mechanism includes sliding grooves formed on both sides of the top of the load-bearing platform. A fixed clamping plate is threadedly connected to one side of the sliding groove, and an electric telescopic column is fixedly connected to the other side of the sliding groove. A sliding clamping plate is fixedly connected to the far end of the electric telescopic column. Adjusters are threadedly connected to both sides of the fixed clamping plate and the sliding clamping plate. An anti-slip positioning plate is rotatably connected to the far end of the adjuster. The anti-slip positioning plates are symmetrically arranged inside the fixed clamping plate and the sliding clamping plate.

[0010] Furthermore, the clamping and fixing mechanism includes an anti-slip rubber pad fixedly connected to the middle of the top of the load-bearing platform, and an anti-roll-off baffle fixedly connected to the outer surface of the load-bearing platform. The anti-roll-off baffle is symmetrically arranged at both ends of the load-bearing platform.

[0011] Furthermore, the lifting and adjusting mechanism includes a rotating plate threadedly connected to the bottom of the load-bearing platform, a rotating cross plate rotatably connected to the bottom of the rotating plate, limit members rotatably connected to both sides of the rotating cross plate, a meniscus rotatably connected to the bottom of the rotating cross plate, a transmission assembly threadedly connected to the inside of the meniscus, and a stable base plate fixedly connected to the outer surface of the transmission assembly.

[0012] Furthermore, the transmission assembly includes a servo motor fixedly connected inside the stabilizing base plate. The output end of the servo motor is fixedly connected to a main rotating shaft. A rotating belt is rotatably connected to the outer surface of the main rotating shaft.

A bearing is rotatably connected to the distal end of the rotating threaded rod. The outer surface of the bearing is fitted into the interior of the stabilizing base plate. The meniscus is threadedly connected to the outer surface of the rotating threaded rod.

[0013] Furthermore, the stabilizing and safe mechanism includes shock-absorbing dampers threaded to the four corners of the bottom of the stabilizing base plate, shock-absorbing telescopic springs sleeved on the outer surface of the shock-absorbing dampers, and ground support plates fixedly connected to the bottom of the shock-absorbing dampers and shock-absorbing telescopic springs.

[0014] Furthermore, the stabilizing and safe mechanism includes connecting plates fixedly connected to both sides of the stabilizing base plate, telescopic bases fixedly connected to the bottom of the connecting plates, the connecting plates and telescopic bases being symmetrically arranged on both sides of the stabilizing base plate, and shock-absorbing wheels fixedly connected to the four corners of the bottom of the ground support plate.

Whether dealing with complex ground environments during tool movement or absorbing vibrations generated by equipment operation during operation, it can exert excellent shock absorption effects, reduce vibration damage to equipment parts, extend tool life, and at the same time ensure the personal safety of operators and the normal operation of surrounding equipment. The lifting and adjusting mechanism is driven by a servo motor, realizing the smooth and precise lifting of the load-bearing platform, enhancing the stability of the lifting process, ensuring that the tool remains stable during roller replacement, and reducing the safety risks and probability of equipment damage caused by equipment shaking.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a quick replacement tool for belt conveyor rollers, including a load-bearing platform 1, a clamping and fixing mechanism 2, a lifting and adjusting mechanism 3, and a stabilizing and safety mechanism 4. The clamping and fixing mechanism 2 is fixedly connected to the top of the load-bearing platform 1, the lifting and adjusting mechanism 3 is threadedly connected to the bottom of the load-bearing platform 1, and the stabilizing and safety mechanism 4 is fixedly connected to the bottom of the lifting and adjusting mechanism 3.

[0027] The following section will explain the specific setup and function of its clamping and fixing mechanism 2, lifting and adjusting mechanism 3, and stabilizing and safety mechanism 4.

[0028] In this embodiment: the clamping and fixing mechanism 2 includes sliding grooves 21 opened on both sides of the top of the load-bearing platform 1. A fixed clamping plate 22 is threadedly connected to one side of the sliding groove 21, and an electric telescopic column 23 is fixedly connected to the other side of the sliding groove 21. A sliding clamping plate 24 is fixedly connected to the far end of the electric telescopic column 23. Adjusters 25 are threadedly connected to both sides of the fixed clamping plate 22 and the sliding clamping plate 24. An anti-slip positioning plate 26 is rotatably connected to the far end of the adjuster 25. The anti-slip positioning plate 26 is symmetrically arranged inside the fixed clamping plate 22 and the sliding clamping plate 24.

[0029] The effects achieved by the above components are as follows: the electric telescopic column 23 can quickly adjust the distance between the fixed clamping plate 22 and the sliding clamping plate 24, adapting to rollers of different diameters, greatly improving the clamping efficiency of rollers of different specifications; when the anti-slip positioning plate 26 contacts the roller surface, it can closely fit the rollers with different surface shapes, further enhancing the fixing effect on the rollers and preventing the rollers from sliding and rotating during replacement.

[0030] Specifically, the clamping and fixing mechanism 2 includes threaded holes 27 evenly spaced on the top of the load-bearing platform 1, and bolts 28 are threadedly connected to both sides of the fixed clamping plate 22. The fixed clamping plate 22 is threadedly connected to the top of the load-bearing platform 1 by the bolts 28. The fixed clamping plate 22 and the sliding clamping plate 24 are symmetrically arranged on both sides of the load-bearing platform 1.

[0031] The effect achieved by the above components is to facilitate the adjustment of the lateral position of the fixed clamping plate 22 on the load-bearing platform 1 according to actual needs, so as to adapt to belt conveyor rollers with different wheelbases and ensure the balanced distribution of clamping force on the rollers.

[0032] Specifically, the clamping and fixing mechanism 2 includes an anti-slip rubber pad 29 fixedly connected to the middle of the top of the load-bearing platform 1, and an anti-roll-off baffle 210 fixedly connected to the outer surface of the load-bearing platform 1. The anti-roll-off baffle 210 is symmetrically arranged at both ends of the load-bearing platform 1.

[0033] The effects achieved by the above components are as follows: the anti-slip rubber pad 29 can increase the friction with the roller, preventing the roller from rolling on the load-bearing platform 1; the anti-roll-off baffle 210 can effectively prevent the roller from accidentally rolling off during handling or lifting, thus improving operational safety.

[0034] Specifically, the lifting and adjusting mechanism 3 includes a rotating plate 31 threadedly connected to the bottom of the load-bearing platform 1, a rotating cross plate 32 rotatably connected to the bottom of the rotating plate 31, limit members 33 rotatably connected to both sides of the rotating cross plate 32, a meniscus 34 rotatably connected to the bottom of the rotating cross plate 32, a transmission assembly 35 threadedly connected to the inside of the meniscus 34, and a stable base plate 36 fixedly connected to the outer surface of the transmission assembly 35.

[0035] The effects achieved by the above components are as follows: the limiting component 33 adopts an adjustable limiting structure. By adjusting the position of the limiting component 33, the rotation angle of the rotating cross plate 32 can be limited to ensure the stability of the lifting process. The transmission component 35 is responsible for driving the meniscus 34 to move up and down, thereby driving the rotating cross plate 32 to rotate, so as to achieve precise adjustment of the height of the load-bearing platform 1.

[0036] Specifically, the transmission assembly 35 includes a servo motor 351 fixedly connected inside the stable base plate 36. The output end of the servo motor 351 is fixedly connected to a main rotating shaft 352. A rotating belt 353 is rotatably connected to the outer surface of the main rotating shaft 352. A driven rotating shaft 354 is rotatably connected inside the rotating belt 353. A rotating threaded rod 355 is fixedly connected to the outer surfaces of the main rotating shaft 352 and the driven rotating shaft 354. A bearing 356 is rotatably connected to the far end of the rotating threaded rod 355. The outer surface of the bearing 356 is fitted into the interior of the stable base plate 36. A meniscus 34 is threadedly connected to the outer surface of the rotating threaded rod 355.

[0037] The effect achieved by the above components is as follows: the servo motor 351 drives the main rotating shaft 352 to rotate, and the rotating belt 353 drives the rotating shaft 354 to rotate synchronously, thereby causing the rotating threaded rod 355 to rotate, so that the meniscus 34 can move left and right along the rotating threaded rod 355. The rotating threaded rod 355 has high transmission efficiency and strong load-bearing capacity, ensuring that the load-bearing platform 1 can be raised and lowered smoothly and accurately, meeting the replacement needs of rollers in different installation positions.

[0038] Specifically, the stabilizing and safe mechanism 4 includes shock absorbers 41 threadedly connected to the four corners of the bottom of the stabilizing base plate 36. Shock absorbers 41 are fitted with shock absorbers 42 on their outer surface. Ground support plates 43 are fixedly connected to the bottom of the shock absorbers 41 and the shock absorbers 42.

[0039] The effects achieved by the above components are as follows: The damper 41 adopts a hydraulic damping structure. The damper 41 and the damping extension spring 42 work together to effectively absorb vibration, reduce the vibration amplitude, and reduce the impact of vibration on equipment and operation.

[0040] Specifically, the stabilizing and safe mechanism 4 includes connecting plates 44 fixedly connected to both sides of the stabilizing base plate 36, and telescopic bases 45 fixedly connected to the bottom of the connecting plates 44. The connecting plates 44 and the telescopic bases 45 are symmetrically arranged on both sides of the stabilizing base plate 36, and shock-absorbing wheels 46 are fixedly connected to the four corners of the bottom of the ground support plate 43.

[0041] The effects achieved by the above components are as follows: the telescopic base 45 adopts a telescopic structure driven by an electric push rod, which can be freely extended and retracted. By adjusting its extension length, it can adapt to different ground flatness, further enhancing the stability of the tool. The shock-absorbing wheel 46 is equipped with a spring shock-absorbing structure, which can reduce bumps during movement and achieve rapid braking, ensuring the stability of the tool during operation.

[0042] Working principle: When using the quick change tool for the belt conveyor roller, first adjust the position of the fixed clamping plate 22 in the threaded hole 27 at the top of the load-bearing platform 1 by adjusting the adjusting bolt 28 according to the specifications of the belt conveyor roller, so that the initial distance between the fixed clamping plate 22 and the sliding clamping plate 24 is slightly larger than the roller diameter. Rotate the adjuster 25 to adjust the anti-slip positioning plate 26 to an angle that matches the shape of the roller surface. Move the tool to a suitable position under the roller to be replaced on the belt conveyor. Depending on the flatness of the ground, start the electric push rod of the telescopic base 45 and adjust the extension length of the telescopic base 45 to stably support the tool on the ground.

[0043] The servo motor 351 of the lifting adjustment mechanism 3 is started by the control panel. The servo motor 351 drives the main rotating shaft 352 to rotate, which is driven by the rotating belt 353 to rotate synchronously from the rotating shaft 354. The rotating threaded rod 355 rotates, which drives the meniscus 34 to move left and right along the rotating threaded rod 355. The rotating cross plate 32 rotates, and the height of the load-bearing platform 1 is adjusted. When the top of the load-bearing platform 1 is roughly aligned with the center line of the roller, the servo motor 351 is stopped.

[0044] Start the electric telescopic column 23 of the clamping and fixing mechanism 2, and the sliding clamping plate 24 moves along the sliding groove 21 toward the fixed clamping plate 22 until it clamps the roller. Fine-tune the adjuster 25 according to the roller surface adhesion to make the anti-slip positioning plate 26 fit tightly against the roller surface.

[0045] Use appropriate disassembly tools to remove the connecting bolts 28 and couplings between the old roller and the belt conveyor frame, conveyor belt and other components. Restart the servo motor 351 and slowly adjust the height of the load-bearing platform 1 to smoothly detach the old roller from the belt conveyor.

[0046] Release the telescopic base 45 from its fixed position, turn off the electromagnetic brake of the shock-absorbing wheel 46, push the tool, and transport the old roller to the designated storage or repair location via the shock-absorbing wheel 46.

[0047] Place the new roller on the load-bearing platform 1. Following the reverse steps of disassembling the old roller, first adjust the height of the load-bearing platform 1 using the lifting adjustment mechanism 3 to bring the new roller to a suitable installation position. Then, use the clamping and fixing mechanism 2 to fix the new roller. Using the installation tools, connect the new roller to the connecting parts of the belt conveyor frame, conveyor belt, and other components in sequence to ensure a firm connection.

[0048] After the new roller is installed, start the servo motor 351 to lower the load-bearing platform 1 to the initial position, release the electric telescopic column 23 to separate the sliding clamping plate 24 from the fixed clamping plate 22, adjust the telescopic base 45 to retract, move the tool to the designated storage position, and perform cleaning, lubrication and other maintenance work on the tool to prepare it for the next use.
