Title:
ENDLESS-ROPE-TYPE VERTICAL SHAFT LIFTING JOINT DEBUGGING AND TESTING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/073582
Kind Code:
A1
Abstract:
Disclosed is an endless-rope-type vertical shaft lifting joint debugging and testing apparatus. The apparatus is composed of a support foundation (3), a hydraulic loading apparatus (1), a winding guide and loading apparatus (2) and an endless steel wire rope (4), wherein the hydraulic loading apparatus (1) is mounted on a platform of the support foundation (3) in a straddling manner in a horizontal transverse direction, and the winding guide and loading apparatus (2) is mounted at the bottom of an inner side of a sandwiched wall of two sub-foundations of the support foundation (3) in the horizontal transverse direction. By means of a closed cycle of an endless rope, different lifting distances and lifting speeds can be simulated, and on the basis of principles of a hydraulic cylinder pressing against the steel wire rope and a bidirectional hydraulic pump providing load damping, loads on two sides of a winding drum are simulated. The winding guide and loading apparatus based on lead screw drive is used for being adapted to different diameters of the winding drum, and a rope distance positioning plate is used for being adapted to different numbers of steel wire ropes and different steel wire rope spacing so as to reliably evaluate the bearing performance of a main shaft apparatus, the slide-proof performance of a friction pad and the braking performance of a brake, such that joint debugging and testing can be performed on vertical shaft lifters of various specifications before on-site installation.
