Description

Technical Field

[0001] The utility model relates to the technical field of cable suspension of a transfer machine, in particular to a cable suspension bridge device of a transfer machine. Background Art

[0002] The full name of the transfer machine is the scraper transfer machine for the chute. It is a bridge-type scraper conveyor installed in the section transport level tunnel at the exit of the working face of the mine. When working, one end is overlapped with the conveyor of the working face, and the other end is connected to the tail of the belt conveyor. Its role in the three-machine matching of large-scale comprehensive mining technology is to transfer the coal transported by the scraper on the mining face to the belt conveyor after the bottom plate of the tunnel is raised. The chute bridge-type scraper transfer machine is mainly used for high-yield and high-efficiency comprehensive mechanized working face chute transfer and transportation of coal. It can be used in conjunction with the working face scraper conveyor, crusher and belt conveyor. When in use, the trolley of the transfer machine is overlapped on the guide rail of the belt conveyor and can move along it as a whole, so that the transfer machine can be adjusted as a whole with the moving step of the working face conveyor. The coal is transferred from the working face conveyor to the retractable belt conveyor through the bridge-type transfer machine for transportation.

[0003] When the transfer machine is linked to the self-moving machine tail, it is connected to the cable trough of the self-moving machine tail through a cable extending 400mm outward. In the construction of the prior art, an anchor cable drill rod is often used to transition the cable. However, as the working face boring machine moves forward and backward, if the drill rod is too long, it will threaten the safety of the guards. If the drill rod is not long enough, the cable will automatically slide off the drill rod, and the drill rod cannot be fixed, which brings great hidden dangers to production safety. Therefore, the utility model proposes a cable suspension bridge device for the transfer machine to solve the shortcomings of the prior art. Utility Model Content
