Chain fixing structure and coal pallet connecting device

Abstract

In the chain fixing structure and the coal pallet connecting device of the present invention, the chain fixing structure includes an upper fixing part, a lower fixing part, and a plurality of wedge pins, pressure rods and a plurality of connecting parts for connecting the upper fixing part and the lower fixing part. screw; the upper fixing part cooperates with the lower fixing part and forms a cavity for accommodating the chain; the upper fixing part is provided with multiple sets of connecting protrusions on the end face far away from the lower fixing part, wherein each set of connecting protrusions includes a chain located on the upper fixing part Two connection protrusions on both sides; each wedge pin can be partially inserted into the connection protrusion, and the two wedge pins corresponding to each group of connection protrusions are arranged opposite to each other and cooperate to form a limit part, and the pressure bar presses the limit part, a plurality of connecting screw rods pass through the pressure bar and the upper fixing piece in turn, and are threadedly connected with the lower fixing piece. The invention has the effect of preventing disengagement; at the same time, the wedge pin can be pulled out by loosening the connecting screw rod, and the chain fixing structure can be disassembled from the rear support, so as to facilitate disassembly.

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.
