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

The invention discloses a cable trough, a middle trough and a scraper conveyor. The cable trough is used for a scraper conveyor, including a connecting plate, and also includes: at least two positioning pieces arranged on the connecting plate; each positioning piece includes: a positioning shaft, a first end of the positioning shaft It is connected with the connecting plate; the limiting part is connected with the second end of the positioning shaft, which is a structure protruding in a direction perpendicular to the axial direction of the positioning shaft. The cable trough and the middle trough provided by the present invention have the following advantages: the cable trough and the middle trough are easy to assemble and disassemble, which is conducive to improving construction efficiency; Forming helps to reduce machining processes, improve labor efficiency, and reduce product costs; no bolts, nuts and other components are required, which solves the problem of too many connecting parts, which is not conducive to picking and counting, and there is no problem that connecting parts are easily lost .
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...
