Title:
STEEL WIRE ROPE PRE-TIGHTENING DEVICE FOR CLIMB-FREE LIFT
Document Type and Number:
WIPO Patent Application WO/2021/218983
Kind Code:
A1
Abstract:
A steel wire rope pre-tightening device for a climb-free lift, comprising: a pre-tightening mechanism (100), a pre-tightening bracket (200), and an adjusting mechanism. The pre-tightening mechanism (100) is connected to the pre-tightening bracket (200), and the adjusting mechanism is mounted on the pre-tightening mechanism (100) and the pre-tightening bracket (200) to drive the pre-tightening mechanism (100) to slide up and down relative to the pre-tightening bracket (200). By means of such structural arrangement, the pre-tightening mechanism (100) is connected to a steel wire rope mounting pulley (600), and the pre-tightening mechanism (100) can be adjusted by the adjusting mechanism to slide up and down relative to the pre-tightening bracket (200), thereby adjusting the tension degree of a steel wire rope. Therefore, the steel wire rope of the climb-free lift is maintained in a proper tension degree, thereby effectively ensuring normal and relatively safe operation of the climb-free lift.
