[0025] 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.

[0026] This utility model provides a detachable, wear-resistant brake shoe structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the detachable wear-resistant brake shoe structure includes a brake base plate 1, a brake shoe body 2 disposed above the brake base plate 1, an insert rod 3 fixedly mounted on the brake base plate 1, a fixing block 11 fixedly mounted on the brake shoe body 2, and a disassembly mechanism disposed inside the fixing block 11 for quick loading and unloading.

[0027] The disassembly mechanism includes a fixed cylinder 4 fixedly installed inside the fixed block 11, an mounting block 5 fixedly installed on the inner wall of the fixed block 11, a telescopic rod 6 fixedly installed on the mounting block 5, an insert block 8 fixedly installed on the movable end of the telescopic rod 6, a first spring 7 sleeved on the side surface of the telescopic rod 6, a slot 12 opened inside the insert rod 3 for the insert block 8 to be inserted, a pressing block 9 slidably installed inside the fixed block 11, and an inclined block 10 fixedly installed at the bottom of the pressing block 9.

[0028] The insert 8 passes through the fixing cylinder 4, one end of the first spring 7 is fixedly connected to one side of the mounting block 5, and the other end of the first spring 7 is fixedly connected to one side of the insert 8.

[0029] The pressing block 9 passes through the fixing block 11 and the brake shoe body 2 in sequence. Multiple inclined blocks 10 are provided, and the inclined surfaces of the multiple inclined blocks 10 are respectively attached to the inclined surfaces of the insert block 8.

[0030] When using this detachable wear-resistant brake shoe structure, to install the brake shoe body 2, simply align the fixing cylinder 4 on the brake shoe body 2 with the insert rod 3 and press it directly. The top of the insert rod 3 first contacts the inclined surfaces of the two insert blocks 8, thus squeezing the two insert blocks 8 to both sides. After being squeezed, the insert blocks 8 drive the telescopic rod 6 to retract on the mounting block 5, while the first spring 7 is compressed. When the insert blocks 8 and the slot 12 are on the same horizontal line, under the reaction force of the first spring 7, the insert blocks 8 are re-inserted into the slot 12, completing the installation. The operation is simple. When it is necessary to remove the brake shoe body 2, simply press the pressing block 9. The pressing block 9 drives the inclined block 10 to squeeze the insert blocks 8. After being squeezed, the insert blocks 8 drive the telescopic rod 6 to retract on the mounting block 5, while the first spring 7 is compressed, causing the insert blocks 8 to disengage from the slot 12. At this time, the brake shoe body 2 can be removed, making disassembly convenient.

[0031] In order to reposition all parts after disassembling the brake shoe body 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a second spring 13 is provided inside the fixing block 11, and a pad 14 is slidably connected inside the fixing block 11. The second spring 13 is sleeved on the side surface of the fixing cylinder 4, and the fixing cylinder 4 passes through the pad 14.

[0032] One end of the second spring 13 is fixedly connected to the bottom inner wall of the fixed block 11, and the other end of the second spring 13 is fixedly connected to the bottom of the pad 14. The bottoms of the multiple inclined blocks 10 are in contact with the top of the pad 14.

[0033] When using this detachable wear-resistant brake shoe structure, pressing the pressing block 9 causes the inclined block 10 to squeeze the insert block 8. After being squeezed, the insert block 8 causes the telescopic rod 6 to retract on the mounting block 5, while the first spring 7 is compressed, causing the insert block 8 to disengage from the slot 12. At the same time, the inclined block 10 pushes the pad 14 downward, and the movement of the pad 14 squeezes the second spring 13. When the pressing block 9 is no longer subjected to external force, under the reaction force of the second spring 13, the pad 14 drives the inclined block 10 to move upward, so that the pressing block 9 and the inclined block 10 return to their initial positions, preparing for the next installation of the brake shoe body 2. This design not only ensures the stability and durability of the brake shoe structure, but also greatly improves the efficiency of disassembly and installation, and facilitates maintenance and replacement.

[0034] To facilitate the use of the brake shoe mechanism, such as Figure 1 , Figure 2 and Figure 3 As shown, each of the two brake shoe bodies 2 is fixedly connected to a fixing post 15, and a shoe tension spring 16 is provided between the two fixing posts 15.

[0035] In use, the two ends of the detachable wear-resistant brake shoe structure are respectively sleeved on the two fixed posts 15, so that the brake shoe spring 16 can be stably fixed between the two brake shoe bodies 2. When the brake shoe body 2 is subjected to external force, the brake shoe spring 16 can provide sufficient elasticity, so that the brake shoe body 2 can quickly return to its original position, thereby ensuring the stability and reliability of the braking effect. At the same time, the setting of the brake shoe spring 16 can also keep the gap between the two brake shoe bodies 2 consistent, avoiding the problem of poor braking effect caused by excessive or insufficient gap. This design not only improves the stability and durability of the brake shoe structure, but also further enhances the braking effect, making the brake shoe mechanism more practical and reliable.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
