Lifting driving device and mechanical parking equipment having the same

Abstract

The present invention provides a lifting driving device and a mechanical parking equipment having the lifting driving device. The lifting driving device can not raise a reacting force applied to a bearing even if the winding number of turns of a cable on a traction sheave is increased. The lifting driving device comprises: a diverting pulley (40) arranged opposite to a traction sheave (30) in a cable tension action direction (P) of the traction sheave (30); a support member (50) of which a base part (53) is freely rotatably supported on an output shaft (26) of a driving source (25), and a front end part (54) freely rotatably supports the diverting pulley (40); and a rotation preventing member (57) used for maintaining a relative position relation between the support member (50) and the driving source (25), wherein, the cable (21) is wound on the diverting pulley (40) after being wound on the traction sheave (30), then the cable (21) is wound on the traction sheave (30) again, therefore, the cable (21) is wound on the traction sheave (30) repeatedly.

Description

technical field [0001] The present invention relates to a lifting driving device applied to elevator-type parking equipment, elevator slide parking equipment, passenger elevators, etc., and a mechanical parking equipment equipped with the lifting driving device. Background technique [0002] In the past, elevator-type parking equipment, lift-and-transfer parking equipment, passenger elevators, etc. have an elevating drive device that uses cables to raise and lower lifting bodies (elevator carriers, gondolas, etc.). In this lifting drive device, a counterweight for reducing the hoisting force of the lifting body is provided at the other end of the cable of the lifting body at one end, and the middle part of the cable is hung on the traction sheave of the driving source to perform hoisting action. . In this lifting drive device, the lifting body is raised and lowered by the frictional driving force of the cable suspended from the traction sheave. [0003] As an example of eq...

AI Technical Summary

Problems solved by technology

[0016] Therefore, in order to increase the friction driving force of the lifting drive device 110 and increase the number of winding times of the cable to increase the tension, the above-mentioned overhanging load becomes larger with the increase of the tension, even if the number of windings meets the required transmission maximum torque, There may also be cases where the criteria for the overhanging load cannot be met.

At this time, try to improve the strength of the output shaft 113, output shaft bearings 114, 115, etc., but when trying to improve the strength, the lifting drive device 110 will become complicated and the weight will increase, and special products for strengthening the bearings should be used as needed, resulting in The complexity, size and cost of the lifting drive device 110 make it an impractical lifting drive device
