Abstract

The invention discloses a hoisting mechanism of a monorail hoist and a monorail hoist. The hoisting mechanism comprises a hoisting beam, a hanging part, a sling chain, a moving chain wheel, a distanceadjusting chain wheel and a power mechanism, wherein the hanging part is hung below the hoisting beam through the sling chain and comprises a hanging seat and a hanging member connected below the hanging seat; the moving chain wheel is arranged on the hanging seat; the distance adjusting chain wheel and the power mechanism are spaced in parallel on the hoisting beam; the power mechanism comprisesa fixed chain wheel and a drive part for driving the fixed chain wheel to rotate; the fixed chain wheel drives the sling chain to move under the drive of the drive part, so as to raise or lower the hanging part; one end of the sling chain is fixed on the hoisting beam, and the other end of the sling chain is sequentially meshed with the moving chain wheel, the fixed chain wheel and the distance adjusting chain wheel; or the other end of the sling chain is sequentially meshed with the moving chain wheel, the distance adjusting chain wheel and the fixed chain wheel. According to the hoisting mechanism of a monorail hoist and the monorail hoist disclosed by the invention, a multi-layer structure is not needed, a hoisting object is lifted high, and the structure is simple.

Description

technical field [0001] The invention relates to the field of hanging rail locomotives, in particular to a hoisting mechanism of a monorail crane and the monorail crane. Background technique [0002] A kind of monorail crane is often used to transport goods and personnel in special occasions such as coal mine roadways, road tunnels, and railway tunnels. The main advantages of monorail crane transportation are: first, the monorail crane has a small cross-section, and the space utilization rate of the roadway section is high; The second is that it can be used for continuous non-reloading transportation of level roads and inclined roads, and its transport load is not limited by the conditions of the bottom plate, and can run in various vertical curves, horizontal curves and complex curves; The reloaded auxiliary transportation can be used for auxiliary transportation operations connecting the main transportation roadway and the mining area roadway. [0003] A lifting beam is ar...
