Cable chute, middle chute and scraper conveyer

Abstract

The invention discloses a cable chute, a middle chute and a scraper conveyer. The cable chute for the scraper conveyer comprises a connecting plate, at least two positioning members, each positioning member comprises a positioning shaft and a limiting portion, the first end of every positioning shaft is connected to the connecting plate, and each limiting portion is connected with the second end of the corresponding positioning shaft and is in a structure protruding in a direction perpendicular to the axis of the positioning shaft. The cable chute and the middle chute have the advantages that the cable chute and the middle chute are convenient to demount and mount, thus construction efficiency can be improved; positioning gaps, used for connecting the cable chute, of a bent plate unit of the middle trough can be made along with blanking of a bent plate, thus machining process can be shortened, labor efficiency can be improved and product cost can be reduced; the parts such as bolts and nuts are not required, thus the problem that high quantity of the connectors is unfavorable for picking and counting and the problem that the connectors are easily lost are solved.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to a cable trough, a middle trough and a scraper conveyor. Background technique [0002] The cable trough for the scraper conveyor is mainly used to carry the cables and water pipes that move with the shearer, and the cables and water pipes for the scraper conveyor. At the same time, the connecting plate of the cable trough can also act as a coal retaining plate, so that the coal is not easy to overflow the scraper conveyor during transportation, which has the functions of ensuring the recovery rate of coal and protecting personal safety. [0003] At present, the cable trough of the scraper conveyor is connected to the middle trough in the following way: the connecting plate of the cable trough is connected to the bent plate assembly of the middle trough through several (usually 8) square-diameter round-head bolts to ensure The detachability of the cable trough and the st...

AI Technical Summary

Problems solved by technology

Therefore, the installation and disassembly of the cable duct is inconvenient, the workload is large, time-consuming and labor-intensive, and the labor productivity is low

[0005] 2. The square hole or waist-shaped hole used for connection on the bent plate assembly in the middle groove needs to be added by machine, because its structure cannot be directly blanked and formed, resulting in an increase in cost

[0006] 3. There are many bolts, nuts and washers used for the connection between the cable trough and the middle trough required by the whole machine. It takes time and effort to pick up and check the materials, and it is easy to lose during the installation and commissioning process, which further affects the cable trough and the middle part. Groove removal efficiency
