Description

Technical Field

[0001] This utility model relates to the field of mining conveying equipment technology, and in particular to an anti-loosening scraper assembly and scraper conveying equipment for underground scraper conveying equipment in coal mines. Background Technology

[0002] A set of scraper conveyor equipment in an underground coal mine face requires the installation of hundreds or thousands of scraper components. Due to factors such as vibration, collision, and scraping during the use of scraper components, fasteners are prone to loosening and falling off. Once this happens, it will cause the scraper chain to jam and break, and cause reverse impact to the drive unit, resulting in a series of serious domino-like equipment failures.

[0003] Coal mines generally adopt a "one-shift maintenance, two-shift production" work mode. Within the limited maintenance time, it is impossible to spend a lot of time on the maintenance of scraper components. Therefore, technical means must be used to avoid or slow down the occurrence of situations such as scraper components becoming loose and falling off. Summary of the Invention

[0004] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide an anti-loosening scraper assembly for underground scraper conveyor equipment in coal mines.

[0005] An anti-loosening scraper assembly for underground scraper conveyor equipment in coal mines includes a scraper, a chain plate, and a connecting rod. The scraper has a first spherical recess and a first mounting hole communicating with the first spherical recess. The chain plate has a second spherical recess and a second mounting hole communicating with the second spherical recess. One end of the connecting rod is fixedly provided with a clamping end built into the second spherical recess. The other end of the connecting rod is sequentially inserted into the second mounting hole and the first mounting hole, and the scraper and the chain plate are adhered and fastened by a locking part fitted on the end of the connecting rod and built into the first spherical recess.

[0006] Preferably, the lower end face of the locking part adopts an arc-shaped surface that matches the contact surface of the first spherical socket.

[0007] Preferably, the upper end face of the pressing end adopts an arc-shaped surface that matches the contact surface of the second spherical socket.

[0008] Preferably, the locking part and the connecting rod are connected by a thread.

[0009] Preferably, the locking part has a non-metallic ring embedded inside.

[0010] It is also necessary to provide a scraper conveyor.

[0011] A scraper conveyor includes an anti-loosening scraper assembly for underground coal mine scraper conveyors, a head section, a tail section, and a middle trough section; the head section, the middle trough section, and the tail section are connected in sequence, the anti-loosening scraper assembly is assembled with a scraper chain, and the scraper assembly is continuously rotated along the head section, the middle trough section, and the tail section by the scraper chain driven by the head section.

[0012] Compared with the prior art, the anti-loosening scraper assembly and scraper conveying equipment for underground scraper conveyors in coal mines provided by this utility model include a scraper, a pressure chain plate, and a connecting rod; a first spherical cavity is provided on the scraper, and a first mounting hole communicating with the first spherical cavity is provided on the scraper; a second spherical cavity is provided on the pressure chain plate, and a second mounting hole communicating with the second spherical cavity is provided on the pressure chain plate; one end of the connecting rod is fixedly provided with a pressing end built into the second spherical cavity; the other end of the connecting rod is sequentially inserted into the second mounting hole and the first mounting hole, and the scraper and the pressure chain plate are adhered and fastened by a locking part fitted on the end of the connecting rod and built into the first spherical cavity. This invention designs the contact surfaces of the locking part, the pressing end, the scraper, and the pressure chain plate as spherical structures, which increases the contact area and significantly increases the contact friction, ensuring that the locking part and the pressing end are completely in contact with the scraper and the pressure chain plate after tightening. The lower end face of the locking part and the upper end face of the pressing end are designed as spherical structures, which can automatically align and center in the first and second spherical recesses, reducing the precision requirements of the parts manufacturing and assembly process and improving economy.
