Description

A kind of directive wheel underneath type cargo lift

Technical field

This utility model provides a kind of cargo lift, is specifically related to a kind of directive wheel underneath type cargo lift.

Background technology

General, the directive wheel of existing cargo lift is substantially all the top being arranged on car frame, and traction machine is worm gear snail Bar structure, rope speed is than the arrangement using 2:1 structure.In such cases, it is desirable to the headroom height of elevator hoistways is bigger, Often some mill constructions do not reach requirement；Furthermore owing to worm and gear traction machine structure is complicated, volume is big so that elevator(lift) machine room Area increases；And owing to rope speed is than 2:1 structure so that traction machine spandrel girder stress is relatively big, for improving weight capacity, spandrel girder The shaped steel of large size must be selected.

Concrete, existing directive wheel overhead cargo lift has the drawback that leading of 1. existing cargo lifts Be substantially all the top being arranged on car frame to wheel, this just requires that the headroom height of elevator hoistways is bigger, often some factories Building does not reaches requirement；The most existing cargo lift machine room area requires big, and building cost is had a larger increase；3. traction machine holds Weight beam selects the shaped steel of large size, increases elevator cost；4. rope speed is than 2:1, and worm gear structure do not selected by traction machine, But select permanent-magnet synchronous structure traction machine, then the purchase cost of traction machine increases considerably.
