Chain fixing structure and coal supporting plate connecting device

Abstract

The invention discloses a chain fixing structure and a coal supporting plate connecting device. The chain fixing structure comprises an upper fixing part, a lower fixing part, a plurality of wedge pins, a pressing rod and a plurality of connecting screw rods, wherein the wedge pins, the pressing rod and the connecting screw rods are used for connecting the upper fixing part and the lower fixing part; the upper fixing part and the lower fixing part are matched to form a cavity for containing a chain; a plurality of groups of connecting convex frames are arranged on the end surface, far away from the lower fixing part, of the upper fixing part, and each group of connecting convex frames comprises two connecting convex frames positioned on the two sides of the upper fixing part; each wedge pin can be partially inserted into the corresponding connecting convex frame, and the two wedge pins corresponding to each group of connecting convex frames are oppositely arranged and matched to form alimiting part; and the pressing rod abuts against the limiting part, and the connecting screw rods sequentially penetrate through the pressing rod and the upper fixing part and are in threaded connection with the lower fixing part. The chain fixing structure has the effect of preventing disengagement; and meanwhile, the wedge pins can be pulled out by unscrewing the connecting screw rods, and thechain fixing structure can be disassembled from a rear support, so that the effect of being convenient to disassemble is achieved.

Description

technical field [0001] The invention belongs to the technical field related to mechanical manufacturing, in particular to a chain fixing structure and a coal pallet connecting device. Background technique [0002] The coal loading car is a coal loading machine on the side of the coke oven, which is used to send coal cakes into the carbonization chamber. The main operating components include a traveling system, a coal charging system, and a head and tail dust removal device. The coal loading system includes a power unit, a coal box, and a coal plate supporting device. The coal support plate is connected with the rear support, and the rear support is connected with the roller chain, relying on the power system to drive the chain, driving the coal support plate to move, and sending the coal cakes tamped on the coal support plate to the carbonization chamber. [0003] At present, the coal support plate is connected with the post-production. The two pieces are an integral mechan...

AI Technical Summary

Problems solved by technology

[0003] At present, the coal support plate is connected with the post-production. The two pieces are an integral mechanism. When replacing, they do not need to be disassembled. The connection with the chain is disconnected for overall disassembly and assembly. The coal support plate is a vulnerable part and needs to be repaired and replaced every year. The connection between the rear support of the coal support plate and the chain is fastened by bolts. The stability of the connection between the rear support of the coal support plate and the chain is not high, and it is easy to disengage, and the buckle connected to the chain needs to be disassembled when disassembling. It is fastened by four hexagon socket screws, and the screws cannot be seen directly during disassembly. Relying on the experience of the mechanic to judge the position of the socket socket for disassembly and installation, disassembly and installation are inconvenient and time-consuming, which increases the difficulty of maintenance and affects coke production.
