Description

Technical Field

[0001] The utility model relates to the technical field of coal mining machinery and equipment, in particular to a new modular convex groove for a transfer machine. Background Art

[0002] In the fully mechanized mining face, the transfer machine is the main equipment for fully mechanized mining and transportation in coal mines. Its function is to transfer the coal transported by the scraper conveyor to the belt conveyor after it is raised from the bottom of the tunnel. Its conveying capacity is large and the chain speed is high, so the trough is easy to wear. When in use, the head of the transfer machine overlaps with the tail of the belt conveyor. In order to ensure sufficient overlap length and space, the horizontal section chute of the transfer machine on the ground is led to the climbing section by the groove, and then the climbing section is led to the horizontal bridge section through the convex groove. This is the main function of the convex groove.

[0003] During the transfer process, the convex groove is the most susceptible to wear. The convex groove parts of domestic coal mines are all integral cast-welded structures, mainly welded after processing of the two side vertical plates, middle plates, bottom plates and other parts. The disadvantages are: the convex groove is a vulnerable part, and the middle plate is the most susceptible to cracking and damage; when replacing, the entire convex groove must be replaced, but the overall replacement of the convex groove is expensive and difficult to replace, and it also causes waste of parts such as the vertical plates.

[0007] Furthermore, a clamping groove is provided on the surface of the lower middle plate, and the module plate group is arranged inside the clamping groove. Along the width direction of the convex groove body, a plurality of module plate groups are arranged between the two side plates.

[0008] Furthermore, the module plate set includes two first module plates arranged opposite to each other, and the abutting sides of the two first module plates are respectively provided with tenons and mortises for clamping.

[0009] Furthermore, a second module board clamped therewith is disposed at the end of the first module board, and a plurality of second module boards are disposed, and the plurality of second module boards are symmetrically mounted at the two ends of the first module board.

[0010] Furthermore, the side edges of the first module board and the second module board that abut against each other are inclined, and the sides of two adjacent first module boards with equal lengths abut against each other.

[0011] Furthermore, two ends of the lower middle plate are respectively provided with a clamping plate, the thickness of the clamping plate is greater than the thickness of the lower middle plate to form the clamping groove, and the upper surface of the module plate group is flush with the upper surface of the clamping plate.

[0012] Furthermore, the convex groove body also includes a bottom plate, two side plates are relatively arranged on both sides of the upper surface of the bottom plate, and upper edges are respectively arranged on the opposite sides of the two side plates, and the middle plate assembly is arranged between the upper edges and the bottom plate.
