Description

Technical Field

[0001] The utility model relates to the technical field of equipment structure improvement, in particular to a centering structure of a chain scraper. Background Art

[0002] Chain scrapers are widely used in coal mining and the transportation of mineral raw materials. They can transport cargo both upward and downward, and their transport capacity is unaffected by cargo size and humidity. Their compact height facilitates loading, and their length is easily adjustable. Their robust construction makes them suitable for use in coal blasting and loading work surfaces.

[0003] Chain scrapers primarily rotate by driving a drive chain driven by a drive gear, which in turn drives the scraper blades. However, when the drive gear and chain mesh, a gap exists between the chain and the drive gear, causing axial movement and misalignment in the chain scraper, which in turn shortens the equipment's service life. Therefore, a chain scraper alignment mechanism is needed to address these issues. Utility Model Content

[0004] Since the prior art has the above-mentioned defects, the utility model provides a centering structure for a chain scraper, which can effectively suppress the axial movement of the chain scraper during operation, so that the scraper runs in a centered manner, thereby extending its service life.

[0005] To achieve the above-mentioned object, the utility model provides a centering structure of a chain scraper, wherein the driving gear of the chain scraper drives the driving chain to rotate cyclically, and the driving chain drives a plurality of scrapers to rotate cyclically in sequence through the chain roller on the chain bracket; the characteristic is that the centering structure includes a positioning slide, a connecting rod and a rolling bearing;

[0006] The positioning slide is fixedly connected to the chain bracket and is arranged toward the scraper. One end of the connecting rod is fixedly connected to the scraper, and the other end is connected to a rolling bearing. The rolling bearing is limited to slide inside the positioning slide.

[0007] The centering structure uses a connecting rod to connect the scraper and the rolling bearing. The rolling bearing is limited by a positioning slideway, thereby limiting the axial movement of the scraper and ensuring the centering operation of the scraper.

[0008] Furthermore, the longitudinal center line of the positioning slide coincides with the longitudinal center line of the scraper, so that the rolling bearing and the center of gravity of the scraper are directly opposite, which can better control the movement of the scraper as a whole.

[0009] Furthermore, the positioning slideway comprises two angle steels fixedly connected to the chain bracket, and the space between the two angle steels constitutes the slideway. This technical solution is easy to control the slideway gap and is easy to implement.

[0010] Furthermore, the connecting rod is fixedly connected to the scraper through a thread and a fastening nut at one end thereof.

[0011] Furthermore, the connecting rod is fixedly connected to the rolling bearing via a shaft sleeve.

[0012] Compared with the prior art, the above utility model has the following advantages or beneficial effects:

[0013] (1) The utility model uses a connecting rod to connect the scraper and the rolling bearing. The rolling bearing is limited by a positioning slideway, thereby limiting the axial movement of the scraper and ensuring the scraper's centered operation. The rolling bearing design is adopted, and rolling friction is used instead of sliding friction, which reduces friction resistance and ensures smooth operation of the equipment.

[0014] (2) The utility model has a simple structure, is relatively easy to maintain, and has an extremely low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example

[0024] Take the chain scraper for limestone transportation as an example, see Figure 1 and Figure 2 The drive gear 11 of the chain scraper drives the drive chain 12 to rotate cyclically. The drive chain 12 drives the scrapers 14 to rotate cyclically in sequence through the chain roller 13 on the chain bracket 15. The drive gear 11 is supported by the drive mechanism bracket 16. A chain roller 13 is installed on one side of the drive chain 12. The chain roller 13 runs on the chain roller bracket 17, thus ensuring that the chain scraper can rotate smoothly. Figure 2 and Figure 3 This embodiment provides a centering structure for the chain scraper, comprising a positioning slide 21, a connecting rod 22, and a rolling bearing 23. The positioning slide 21 is fixedly connected to the chain bracket 15 and faces toward the scraper 14. The connecting rod 22 has one end fixedly connected to the scraper 14 and the other end connected to the rolling bearing 23. The rolling bearing 23 is constrained to slide inside the positioning slide 21.

[0025] The centering structure uses a connecting rod to connect the scraper and the rolling bearing. The rolling bearing is limited by the positioning slide 21, thereby limiting the axial movement of the scraper, thereby ensuring the centering operation of the scraper.

[0026] As a preferred technical solution, further: the longitudinal center line of the positioning slide 21 coincides with the longitudinal center line of the scraper 14, so that the rolling bearing and the center of gravity of the scraper are directly opposite, which can better control the movement of the scraper as a whole.

[0027] As a preferred technical solution, the positioning slide 21 further comprises two angle steels 24 fixedly connected to the chain bracket 15, with the space between the two angle steels 24 forming the slideway. This technical solution facilitates control of the slideway gap and is easy to implement. More specifically, the positioning slide 21 comprises an upper bracket and a lower hanger, wherein the lower hanger can be connected to the underside of the chain bracket 15 via a mounting plate and bolts.

[0028] As a preferred technical solution, further: the connecting rod 22 is fixedly connected to the scraper 14 through a thread and a fastening nut at one end thereof. The connecting rod 22 is fixedly connected to the rolling bearing 23 through a shaft sleeve.

[0029] From the above construction structure and process, it can be seen that the utility model limits the axial movement of the scraper by limiting the rolling bearing connected to the scraper, so that the chain scraper keeps running in the center. At the same time, it adopts a rolling bearing design, uses rolling friction instead of sliding friction, reduces friction resistance, and ensures smooth operation of the equipment.

[0030] In summary, the present invention provides a centering structure for a chain scraper, characterized by comprising a positioning slideway, a connecting rod, and a rolling bearing. The positioning slideway is fixedly connected to a chain bracket and is positioned toward the scraper. One end of the connecting rod is fixedly connected to the scraper, and the other end is connected to the rolling bearing. The rolling bearing is limited to slide inside the positioning slideway. By limiting the position of the rolling bearing connected to the scraper, the present invention can effectively suppress axial movement during operation of the chain scraper, ensuring the scraper operates in a centered manner and thereby extending its service life.

[0031] The standard parts used in this application document (such as rolling bearings) can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology.

[0032] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solution of the present invention, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the present invention.
