Abstract

The utility model discloses a mining explosion-proof monorail hoist adopting permanent magnetic direct-drive transmission. The mining explosion-proof monorail hoist comprises two driving cabs located at the front end and the rear end of the monorail hoist respectively, wherein direct-drive driving devices drive friction wheels to operate on a track through rotation of permanent magnet synchronous direct-drive motors, and hydraulic braking devices are mounted on the direct-drive driving devices; a power source device is connected with the track through a cross beam and a carrying trolley; a frequency conversion control device and a hydraulic power device are placed in a framework and connected with the track through the carrying trolley; and the driving cabs are connected with thedevices through connecting rods. According to the monorail hoist, supplied power of the power source device is subjected to inversion conversion by the frequency conversion control device and supplies to the permanent magnet synchronous direct-drive motors in the direct-drive driving devices and a motor in the hydraulic power device respectively, and the hydraulic power device supplies a power source to hydraulic braking on the direct-drive driving devices of the monorail hoist. The mining explosion-proof monorail hoist adopting permanent magnetic direct-drive transmission adopts a direct-drive transmission mode of the permanent magnet synchronous motors, and has the advantages of small size, large tractive force, high transmission efficiency and good energy-saving performance.

Description

Mining explosion-proof type permanent magnet direct-drive transmission monorail hoist
Technical field
The utility model relates to a kind of monorail hoist technical field, relates in particular to a kind of mining explosion-proof type permanent magnet direct-drive transmission monorail hoist.
Background technology
The auxiliary conveying equipments that travels on suspended single-track system that monorail hoist is a kind of mobility strong, running velocity is fast, load carrying ability is large, safe and reliable, a monorail hoist can be on changeable slope, multiple tracks trouble, in branched line tunnel, realize continuously through transport without reprinting, not be out of shape by roadway floor, ponding or solid accumulation impact, obtain applying more and more widely in colliery at present.The existing monorail hoist in colliery mainly contains diesel engine monorail hoist and Battery-driven Monorail Main Parameters car, diesel engine monorail hoist is mainly as propulsion source with diesel engine, thereby drive the flourishing running of hydraulic power unit and hydraulic pressure to drive the operation of locomotive, this structure hydraulic systematic comparison complexity, hydraulic tubing and hydraulic joint are more, environment for use is had relatively high expectations, and owing to there being a large amount of coal dusts under coal mine, the fault rate that hydraulic efficiency pressure system occurs is higher; Another kind of Battery-driven Monorail Main Parameters car is to adopt storage battery as power supply, ac variable-frequency electric motor is as propulsion source, there is the shortcomings such as speed adjusting performance is poor, detent torque is little, efficiency is low in ac variable-frequency electric motor, and this electrical motor will support the use and drive monorail crane operation with speed reduction gearing, and this constructional noise is large, fault rate is high, driving efficiency is low.
