Abstract

The invention relates to a hoist with a sky wheel inspection and locking device. Including the friction wheel and the PLC control platform, the steel wire rope is wound around the outer circumference of the friction wheel, one end of the wire rope bypasses the upper sky wheel and connects with the lifting container, the other end of the wire rope bypasses the lower sky wheel and connects with the counterweight, and the lifting container and the counterweight are connected by a tail rope ;The PLC control platform controls the start and stop of the friction wheel, the PLC control platform is connected to the power supply through the wire, the power supply is connected to the changeover switch piece through the wire, the PLC control platform is also connected to the first contact through the wire, and the buzzer switch and the buzzer are connected in series to the warning The lights are connected in parallel, one end of the warning light is connected to the second contact through a wire, and the other end of the warning light is connected to the power supply through a wire. The invention has the advantages of high speed, large lifting capacity and good safety; it can ensure the safety of maintenance personnel who overhaul the sky wheel, and can give warnings to other personnel.

Description

technical field [0001] The invention relates to a hoist with a sky wheel inspection and locking device. Background technique [0002] The hoist is a kind of mining mechanical equipment used to lift minerals, lift personnel and materials, and is suitable for the hoisting system of shafts and inclined shafts in coal, nonferrous metal, and other mines. When the maintenance personnel overhaul the sky wheel of the hoist, other personnel such as signal workers and winch workers cannot confirm the actual operation of the maintenance personnel, which is prone to misoperation and cause safety accidents. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a hoist with a sky wheel inspection and locking device, which has high speed, large lifting capacity, and good safety; it can ensure the safety of maintenance personnel for sky wheel inspection, and can warn others. [0004] The hoist with the sky wheel...
