Description

Technical Field

[0001] This application relates to the technical field of scraper conveyor chains, and in particular to a wear-resistant chain for a scraper conveyor. Background Art

[0002] Scraper conveying equipment is widely used in industrial production, especially in the dust removal and ash conveying system. However, the wear of the chain and pin has always been the main failure point of such equipment, seriously affecting the service life and safety of the equipment.

[0003] Currently, conventional methods mainly extend the service life of the chain and pin by improving the material or heat treatment process. However, these methods cannot fundamentally solve the problems of random rotation of the pin and chain wear caused by factors such as assembly clearance, load fluctuation, and friction.

[0004] The prior art cannot effectively prevent the random rotation of the pin during operation, resulting in increased local wear of the chain, eventually leading to fracture and even scrapping of the entire chain.

[0005] Therefore, this application proposes a wear-resistant chain for a scraper conveyor. Utility Model Content

[0006] A wear-resistant chain for a scraper conveyor proposed in this application solves the problems raised in the above background art; by introducing a self-locking mechanism, it effectively prevents the random rotation of the pin during operation, thus significantly reducing the local wear and fracture risk of the chain. At the same time, by optimizing the material and introducing a lubrication mechanism, the service life of the equipment is further extended and the safety is improved. The locking block is designed as a wedge shape, and its inclined surface cooperates with the locking grooves on the first scraper chain link, the second scraper chain link, and the third scraper chain link to form self-locking. When the pin is subjected to a rotational torque, the inclined surface of the locking block interacts with the locking grooves on the first scraper chain link, the second scraper chain link, and the third scraper chain link, increasing the friction force and preventing the pin from rotating, greatly enhancing the practicability of the device.

[0007] To achieve the above object, this application adopts the following technical solutions:

[0008] A wear-resistant chain for a scraper conveyor includes a first scraper chain link, a second scraper chain link, a third scraper chain link, and pins. There are two pins. The first scraper chain link and the second scraper chain link are connected by one of the pins, and the second scraper chain link and the third scraper chain link are connected by the other pin. Self-locking mechanisms are provided on both of the pins.

[0009] As a preferred embodiment, the self-locking mechanism includes mounting blocks. Both of the mounting blocks are provided on the pin, and a plurality of mounting grooves are formed inside both of the mounting blocks;

[0010] By providing an installation groove on the installation block for installing the main locking component of the self-locking mechanism, the practicality of the device is improved.

[0011] As a preferred embodiment, a spring is provided inside each of the installation grooves, and a locking block is fixedly connected to one end of each spring;

[0012] By providing a combination of multiple springs and locking blocks on the pin shaft, distributed at different positions, the stability and reliability of the self-locking effect are improved, thus enhancing the practicality of the device.

[0013] As a preferred embodiment, a plurality of locking grooves cooperating with the locking blocks are provided on the first scraper link, the second scraper link, and the third scraper link, and the inclined surface of each locking block away from the spring extends into the locking groove;

[0014] Through the interaction between the inclined surface of the locking block and the locking grooves on the first scraper link, the second scraper link, and the third scraper link, the frictional force is increased to prevent the pin shaft from rotating, thus enhancing the practicality of the device.

[0015] As a preferred embodiment, a lubrication mechanism is provided inside each of the first scraper link, the second scraper link, and the third scraper link. The lubrication mechanism includes an oil inlet hole and an annular groove. Each of the oil inlet hole and the annular groove is respectively provided inside the first scraper link, the second scraper link, and the third scraper link, and each of the oil inlet hole and the annular groove is communicated with each other. A sealing plug is provided inside each of the oil inlet holes;

[0016] Through the oil inlet hole and the annular groove, when the lubricating oil enters from the oil inlet hole, it will spread into the annular groove, enabling the lubricating oil to cover the largest area, thus enhancing the practicality of the device.

[0017] As a preferred embodiment, a plurality of oil outlet holes are provided on the contact surfaces of the first scraper link, the second scraper link, and the third scraper link with the pin shaft respectively, and each of the oil outlet holes communicates with the annular groove;

[0018] By providing the oil outlet holes, the lubricating oil in the annular groove will penetrate through the holes to the pin shaft, achieving a lubricating effect, thus enhancing the practicality of the device.

[0019] As a preferred embodiment, a sponge is provided inside each of the annular grooves, and the sponge is located at the end of the oil outlet hole away from the pin shaft;

[0020] By providing a sponge in the annular groove, the sponge can prevent the lubricating oil from penetrating too fast, resulting in incomplete lubrication. Therefore, the lubricating effect is improved, thus enhancing the practicality of the device.

[0021] Advantages of the present application:

[0022] 1. The wear-resistant chain for scraper conveyor effectively prevents the random rotation of the pin during operation by introducing a self-locking mechanism, thus significantly reducing the local wear and fracture risk of the chain. At the same time, by optimizing the material and introducing a lubrication mechanism, the service life of the equipment is further extended and the safety is improved. The locking block is designed as a wedge shape, and its inclined surface cooperates with the locking grooves on the first scraper link, the second scraper link and the third scraper link to form self-locking. When the pin is subjected to a rotational torque, the inclined surface of the locking block interacts with the locking grooves on the first scraper link, the second scraper link and the third scraper link, increasing the friction force and preventing the pin from rotating, greatly enhancing the practicability of the device;

[0032] Refer to Figures 1-4 , A self-locking mechanism 5 is provided on both of the two pins 4. The self-locking mechanism 5 includes mounting blocks 51. Both of the two mounting blocks 51 are provided on the pin 4. A plurality of mounting grooves 52 are formed inside the two mounting blocks 51. A spring 53 is provided inside each mounting groove 52. One end of each spring 53 is fixedly connected to a locking block 54. A plurality of locking grooves 55 that cooperate with the locking blocks 54 are provided on the first scraper link 1, the second scraper link 2 and the third scraper link 3. And the inclined surface of each locking block 54 away from the spring 53 extends into the locking groove 55; by providing the self-locking mechanism 5 on the pin 4, it is used to prevent the pin 4 from randomly rotating during operation. The spring 53 provides a locking force, so that the locking blocks 54 are closely matched with the locking grooves 55 on the first scraper link 1, the second scraper link 2 and the third scraper link 3 respectively, thereby preventing the pin 4 from rotating.

[0033] Refer to Figures 1-4 , The locking block 54 is designed as a wedge shape. Its inclined surface cooperates with the locking grooves 55 on the first scraper link 1, the second scraper link 2 and the third scraper link 3 to form self-locking. When the pin 4 is subjected to a rotational torque, the inclined surface of the locking block 54 interacts with the locking grooves 55 on the first scraper link 1, the second scraper link 2 and the third scraper link 3, increasing the frictional force and preventing the pin 4 from rotating.

[0034] Refer to Figures 1-3 , By arranging a combination of a plurality of springs 53 and locking blocks 54 on the pin 4 and distributing them at different positions, the stability and reliability of the self-locking effect are improved.

[0035] Refer to Figure 1 , 2, 4. Lubrication mechanisms 6 are provided inside the first scraper link 1, the second scraper link 2, and the third scraper link 3. The lubrication mechanism 6 includes an oil inlet hole 61 and an annular groove 62. Each oil inlet hole 61 and annular groove 62 are respectively opened inside the first scraper link 1, the second scraper link 2, and the third scraper link 3, and each oil inlet hole 61 communicates with the annular groove 62. A sealing plug 63 is provided inside each oil inlet hole 61.

A sponge 65 is provided inside each annular groove 62, and the sponge 65 is located at one end of the oil outlet small hole 64 away from the pin shaft 4; By providing the lubrication mechanism 6, lubricant is regularly injected into the contact parts of the pin shaft 4 and the first scraper link 1, the second scraper link 2, and the third scraper link 3 to reduce friction and further extend the service life.

[0036] Working principle: By providing a self-locking mechanism 5 on the pin shaft 4 to prevent the pin shaft 4 from randomly rotating during operation, a locking force is provided by the spring 53, so that the locking blocks 54 are respectively in close fit with the locking grooves 55 on the first scraper link 1, the second scraper link 2, and the third scraper link 3, thereby preventing the pin shaft 4 from rotating.

[0037] The locking block 54 is designed as a wedge shape, and its inclined surface cooperates with the locking grooves 55 on the first scraper link 1, the second scraper link 2, and the third scraper link 3 to form self-locking. When the pin shaft 4 is subjected to a rotating torque, the inclined surface of the locking block 54 interacts with the locking grooves 55 on the first scraper link 1, the second scraper link 2, and the third scraper link 3 to increase friction and prevent the pin shaft 4 from rotating.

[0038] By providing a combination of multiple springs 53 and locking blocks 54 on the pin shaft 4 and distributing them at different positions, the stability and reliability of the self-locking effect are improved.

[0039] By providing the lubrication mechanism 6, lubricant is regularly injected into the contact parts of the pin shaft 4 and the first scraper link 1, the second scraper link 2, and the third scraper link 3 to reduce friction and further extend the service life.

[0040] In the above measures, the locking block 54 can be made of wear-resistant materials such as ceramics or cemented carbide to improve its wear resistance and service life.

[0041] By introducing the self-locking mechanism 5, the random rotation of the pin shaft 4 during operation is effectively prevented, thus significantly reducing the risk of local wear and fracture of the chain. At the same time, by optimizing the materials and introducing the lubrication mechanism 6, the service life of the equipment is further extended and the safety is improved.
