Description

Technical Field

[0001] The utility model belongs to the technical field of scraper conveying equipment, and specifically relates to a middle trough assembly tooling. Background Technique

[0002] The middle trough is a key component of the scraper conveyor for scenarios such as coal mines.

Therefore, the service life of the middle trough is an important indicator for measuring the service life of the whole machine.

[0003] The splicing process of the middle trough mainly adopts the welding method, that is, the two end side plates (trough sides) are welded to the middle plate. During use, in addition to the bearing force for transporting coal, it also bears the impact force and extrusion force when large coal blocks and rocks are stuck in the trough. Such harsh working conditions pose higher requirements for the assembly of the middle trough components. In particular, the assembly accuracy between the middle plate and the trough side directly affects the smoothness of the scraper chain transportation, and the quality of the assembly accuracy directly affects the service life of the middle trough.
