Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to a portable and efficient tooling for changing load-bearing idlers. Background Technology
[0002] Belt conveyors, also known as rubber belt conveyors or conveyor belt conveyors, are machines that rely on friction to continuously transport materials. They mainly consist of a frame, conveyor belt, idlers, drums, tensioning devices, and transmission devices. Among these, load-bearing idlers typically account for a high proportion of the total number of idlers in a belt conveyor, generally reaching around 80%. Load-bearing idlers support the weight of the conveyor belt and materials, and due to their large number, they wear out quickly. Conventional methods for replacing load-bearing idlers include lifting the conveyor belt with a crane and then replacing the idlers, or prying the conveyor belt with a crowbar and then replacing the idlers. However, replacing load-bearing idlers with a crane is too complicated, and replacing them with a crowbar is not only time-consuming and labor-intensive, but also easily damages the conveyor belt. Neither of these methods is convenient for quickly and safely replacing load-bearing idlers. Therefore, designing a portable and efficient tooling for replacing load-bearing idlers has become a problem that we need to solve. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a portable and efficient tooling for replacing load-bearing idlers.
[0004] To achieve the above objectives, this utility model provides a portable and efficient tooling for changing load-bearing idlers, including a frame and a support frame. The top of the frame is provided with a load-bearing idler, and the top of the load-bearing idler is provided with a conveyor belt. The support frame is sleeved on the outer wall of the frame, and the bottom of the support frame is connected to a first bolt by a thread. The first bolt abuts against the outer wall of the frame, and the top of the support frame is provided with a jack. A lifting assembly is used to assist the jack in lifting the conveyor belt, and the lifting assembly is connected to the jack.
[0005] In the above technical solution, the lifting assembly further includes a main lifting component that is threadedly connected to the outer wall of the top of the jack, an adjusting component that is fixedly installed inside the main lifting component, and an adjusting block that is inserted into the adjusting component.
[0006] In the above technical solution, a connecting block is further fixedly connected to the outer wall of the adjusting block, the connecting block is inserted into the interior of the main lifting member, and a secondary lifting member is fixedly connected to the outer wall of the connecting block.
[0007] In the above technical solution, a stop block is fixedly installed inside the auxiliary lifting member, and a rotating rod is rotatably connected inside the auxiliary lifting member, with the rotating rod located on one side of the stop block.
[0008] In the above technical solution, the outer wall of the rotating rod is further fixedly connected to a threaded adjusting rod inner rod, and the threaded adjusting rod is disposed inside the auxiliary lifting member.
[0009] In the above technical solution, further, sealing blocks are inserted at both ends of the main lifting component, and a second bolt is threadedly connected inside the sealing block, the second bolt being inserted inside the main lifting component.
[0010] Compared with the prior art, the present invention has the following beneficial effects: By setting up a lifting assembly, the conveyor belt can be quickly and completely lifted, separating it from the bottom support rollers. This facilitates the replacement of the support rollers by workers and prevents the inclined parts on both sides of the conveyor belt from falling under their own weight and pressing on the inclined support rollers on the frame, which would affect the replacement of the inclined support rollers. This improves the efficiency of support roller replacement, ensures production continuity, reduces operating costs, and enhances equipment safety. At the same time, when the lifting assembly is folded, it occupies less space, making it easier for tooling personnel to carry and store. Attached Figure Description

[0013] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figures 1 to 2The portable and efficient tooling for changing carrier idlers shown includes a frame 1 and a support frame 4. A carrier idler 2 is installed on the top of the frame 1, and a conveyor belt 3 is installed on the top of the carrier idler 2. The support frame 4 is sleeved on the outer wall of the frame 1. A first bolt 5 is threadedly connected to the bottom of the support frame 4 and abuts against the outer wall of the frame 1. A jack 6 is installed on the top of the support frame 4. A lifting assembly is used to assist the jack 6 in lifting the conveyor belt 3. The lifting assembly is connected to the jack 6. The support frame 4 is equipped with a plug that matches the screw hole on the base of the jack 6. When the jack 6 is placed on top of the support frame 4, the plug on the support frame 4 can limit the horizontal movement of the jack 6 through the screw hole on the base of the jack 6, thereby improving the safety of the tooling and preventing the jack 6 from shifting on the support frame 4 when the lifting assembly is controlled to lift the conveyor belt 3, which would affect the lifting stability of the conveyor belt 3 and create safety hazards.
[0015] like Figures 3 to 4 As shown, the lifting assembly includes a main lifting component 7 connected to the outer wall of the top of the jack 6 by a thread. An adjusting component 8 is fixedly installed inside the main lifting component 7. An adjusting block 9 is inserted into the inside of the adjusting component 8. A connecting block 10 is fixedly connected to the outer wall of the adjusting block 9. The connecting block 10 is inserted into the inside of the main lifting component 7. A secondary lifting component 11 is fixedly connected to the outer wall of the connecting block 10. A stop block 12 is fixedly installed inside the secondary lifting component 11. A rotating rod 13 is rotatably connected inside the secondary lifting component 11. The rotating rod 13 is located on one side of the stop block 12. The inner rod of a threaded adjusting rod 14 is fixedly connected to the outer wall of the rotating rod 13. The threaded adjusting rod 14 is located inside the secondary lifting component 11. A sealing block 15 is inserted into both ends of the main lifting component 7. A second bolt 16 is threadedly connected to the inside of the sealing block 15. The second bolt 16 is inserted into the inside of the main lifting component 7. When the operator needs to adjust the size of the secondary lifting component 11 and the main lifting component 7 after unfolding, the secondary lifting component 11 can be pulled down by rotating the connecting block 10 parallel to the main lifting component 7. At this time, the adjusting block 9 on the connecting block 10 at the end of the secondary lifting component 11 is parallel to the main lifting component 7 and can slide along the inside of the adjusting component 8. After the size adjustment of the secondary lifting component 11 and the main lifting component 7 after unfolding is completed, the operator can rotate the secondary lifting component 11 so that the secondary lifting component 11 rotates relative to the main lifting component 7. The rotation of the secondary lifting component 11 will drive the adjusting block 9 to rotate through the connecting block 10, so that the adjusting block 9 is no longer parallel to the main lifting component 7. At this time, the adjusting block 9 is blocked by the internal slot of the adjusting component 8 and cannot slide along the inside of the adjusting component 8, so as to achieve the effect of quickly adjusting the size of the main lifting component 7 and the secondary lifting component 11 after unfolding, which makes it convenient for the operator to lift conveyor belts 3 of different sizes and improve the applicability of the tooling.
[0016] The threads at the connection between the second bolt 16 and the sealing block 15 are the same as those at the connection between the jack 6 and the main lifting component 7. This prevents a single jack 6 from lifting the conveyor belt 3, or causes excessive deformation of the main lifting component 7 at a location far from the conveyor belt 3. In such cases, the operator can remove the second bolt 16 from the sealing blocks 15 at both ends of the main lifting component 7 and fix the two jacks 6 inside the sealing blocks 15 using threads. This allows the two jacks 6 to support the main lifting component 7 from both sides, increasing the support force and strength of the main lifting component 7. This ensures that the conveyor belt 3 can be lifted stably, preventing excessive deformation at both ends of the main lifting component 7. This allows the operator to adjust the load as needed and makes the product convenient to use.
[0017] Working principle: When the operator needs to replace the carrying idler roller 2, the support frame 4 can be hung on the angle steel of the frame 1, and the first bolt 5 can be tightened to fix the support frame 4 stably on the frame 1. Then, the operator can connect the main lifting component 7 to the lifting rod of the jack 6 through threads, and rotate the two auxiliary lifting components 11 on the main lifting component 7 to both sides until the two auxiliary lifting components 11 have rotated 180 degrees and stopped. Then, the operator can place the jack 6 on the support frame 4 and fit the screw hole of the jack 6 onto the outer wall of the insert block on the support frame 4, so that the jack 6 drives the lifting assembly to be set at the bottom of the conveyor belt 3. At this time, the operator can rotate the auxiliary lifting component 11 to be parallel to the inclined carrying idler roller 2 on the frame 1, and rotate the rotating rod 13 until the thread adjusting rod 14 is blocked by the stop block 12. Then, the operator rotates the outer sleeve of the thread adjusting rod 14 until the thread is adjusted. After the extension bar 14 extends to the bottom of the inner wall of the main lifting component 7, it stops and fixes the inclined angle of the auxiliary lifting component 11 parallel to the carrying idler roller 2. At this time, the angle between the main lifting component 7 and the auxiliary lifting component 11 is the same as the angle between the center part of the conveyor belt and the inclined parts on both sides. Finally, the operator controls the jack 6 to lift the main lifting component 7, so that the main lifting component 7 drives the auxiliary lifting component 11, which is fixed at the angle, to rise together. This allows the main lifting component 7 to lift the center part of the bottom of the conveyor belt 3 and bear the main pressure, while the auxiliary lifting component 11 lifts the inclined parts on both sides of the conveyor belt 3 and bears the remaining pressure. This achieves the effect of quickly lifting the conveyor belt 3 in a comprehensive manner, allowing the conveyor belt 3 to be completely separated from the bottom carrying idler roller 2. This makes it convenient for the operator to replace the carrying idler roller 2 and prevents the inclined parts on both sides of the conveyor belt 3 from falling under their own weight and pressing on the inclined carrying idler roller 2 on the frame 1, which would affect the replacement of the inclined carrying idler roller 2.
