Multi-point synchronization lifting mechanism composed of steel wire flexible shaft

Abstract

The invention relates to a multipoint synchronous lifting mechanism composed of a steel wire flexible shaft. Three upright columns distributed as equilateral triangle are arranged on a base of the multipoint synchronous mechanism; three screw lifter are respectively arranged on permanent seats of the corresponding upright columns tops; one end of a drive shaft of a first and a second screw lifter is provided with a brake and the other end is connected with one end of the corresponding steel wire flexible shaft by a coupling; one end of a drive shaft of third screw lifter is connected with one end of the brake shaft by the coupling and the other end of the brake shaft is connected with the other end of the same steel wire flexible shaft by the coupling; the other end of the drive shaft of the third screw lifter is connected with one end of a large synchronous belt wheel shaft, and the other end of the wheel shaft is connected with the other end of another steel wire flexible shaft by the coupling; the large synchronous belt wheel shaft is connected with a large synchronous pulley by a torque limiter and the large synchronous pulley is connected with a main shaft of a DC motor by a transmission pair. The multipoint synchronous lifting mechanism has the advantages of high synchronous precision, simple structure, low cost, high reliability, low noise, convenient speed regulation, simple installation and convenient matainance.

Description

technical field [0001] The invention relates to a synchronous lifting mechanism, in particular to a lifting mechanism that can be used for machines and equipment that require multi-point synchronous lifting. technical background [0002] The synchronous lifting mechanism is widely used in industrial equipment, such as various lifting platforms, the lifting movement when a certain part of the equipment needs to be opened, etc., especially in some occasions that require precise movement (synchronous error ≤ 1‰), the synchronous lifting mechanism The precision of movement often becomes the key to the operation of the equipment. To improve the accuracy of synchronous motion, the traditional method is to add precision guide devices and many detection methods to the previous synchronous mechanism (such as chain synchronous lifting mechanism, hydraulic synchronous lifting mechanism, etc.) to continuously correct the deviation generated during the movement. As a result, the system ...
