Description

Technical Field

[0001] The utility model belongs to the technical field of overhead passenger devices, in particular to a one-way tail wheel. Background Art

[0002] The overhead passenger device is a device used to transport people. The mining ropeway (overhead passenger device) is mainly used to transport people in the inclined and horizontal tunnels of mines. Its working principle is similar to that of the ground tourist ropeway. It drives the friction wheel on the reducer through an electric motor as a driving device, and uses an overhead infinitely circulating wire rope as a traction load. The wire rope is mainly tensioned by the tail tensioning device and supported by the rope pulley along the way to maintain the freedom and tension of the wire rope between the supporting wheels. The rope grip connects the passenger chair to the wire rope and circulates it to achieve the purpose of transporting people.

[0003] During the use of mining overhead passenger devices, many unpredictable things may happen. When the driving wheel loses control and the power is cut off, the existing tail wheel has no corresponding protection mechanism, so that two adjacent overhead passenger devices collide, causing damage to the equipment, which may seriously endanger the safety of the workers. Secondly, when the workers go uphill, the driving force is insufficient, causing the tail wheel to reverse or idle. The existing tail wheel does not have a corresponding self-locking mechanism, which may cause a series of safety problems. Therefore, there is room for improvement. Utility Model Content
