Description

Technical Field

[0001] The present application belongs to the technical field of coal mine excavation equipment, and specifically relates to a loading and transporting equipment and an excavation equipment. Background Art

[0002] In the relevant technology, with the continuous development of science and technology and productivity, cantilevered roadheaders are more and more widely used in coal mines and mining. Users' requirements for mining equipment are not only efficiency and safety, but also pay more attention to the maintainability of the equipment and the reliability of long-term use. The loading mechanism of the roadheader includes a shovel part and a first conveyor. The first conveyor is usually hinged with the shovel part through an articulated pin to complete the process of the shovel part collecting materials and the first conveyor transporting materials. When the roadheader is maintained after use, the various components need to be disassembled. The disassembly of the first conveyor usually involves pulling out the articulated pin connecting it to the shovel to disassemble it. However, due to factors such as the underground environment in which the roadheader works, the articulated pin is difficult to pull out, difficult to disassemble, and poor maintainability, which affects the normal maintenance work of the roadheader, reduces the working efficiency of the roadheader, and affects production efficiency.

During overhaul maintenance, the pressure plate 180 needs to be removed first, and then the left and right cover plates 140 are removed. The pin 130 can be pushed out axially from the inside to the outside from the cavity of the receiving groove 190, or the pin 130 can be pushed into the cavity of the receiving groove 190 from the outside to the inside, and then the pin 130 can be taken out from the cavity of the receiving groove 190.

[0085] In this embodiment, the cover plate 140 is a bent part, and a countersunk hole 1422 is provided on the upper surface of the cover plate 140. The upper surface of the cover plate 140 and the receiving groove 190 are connected by hexagon socket bolts. The bolts are not higher than the bottom plate of the front chute to prevent the transportation of materials from being affected. The lower half of the cover plate 140 is a quarter transition surface, which is concentric with the connection between the shovel plate and the first conveyor. It forms a cavity with the front end of the receiving groove 190 of the first conveyor.

[0086] In this embodiment, in view of the difficulty in disassembly and poor maintainability of the first conveyor of the conventional tunnel boring machine, which affects the normal maintenance work of the tunnel boring machine, reduces the working efficiency of the tunnel boring machine, and affects the production efficiency. Therefore, a receiving groove 190 is provided at the front end of the first conveyor to realize the quick disassembly of the pin shaft 130 connecting the first conveyor and the shovel plate part 120, thereby reducing the maintenance time of the tunnel boring machine, improving maintainability, and improving the working efficiency of the tunnel boring machine.

[0087] In summary, the beneficial effects of the embodiments of the invention are as follows:

[0088] A receiving groove 190 is provided between the conveyor 110 and the shovel plate 120. By engaging the detachable cover plate 140 with the receiving groove 190, the pin shaft 130 can be pushed into the receiving groove 190 and then taken out, so that the pin shaft 130 can be quickly disassembled, thereby improving the maintainability of the shipping equipment 100 and shortening the maintenance time.
