Abstract

The invention discloses a device for preventing a steel wire rope of a tower crane trolley from separating from a slot. The device comprises a trolley wheel frame, wherein a slot wheel is mounted on the trolley wheel frame; bearings are symmetrically arranged on the slot wall, close to the top end and the bottom end, of one side of the slot wheel; threaded rods are rotatably connected between thetwo bearings; one end of each threaded rod sequentially passes through the corresponding bearing and the slot wheel wall to extend outwards; symmetrical threads with reverse directions are arranged onthe threaded rods between the two bearings; two symmetrical clamping plates are arranged in the slot wheel slot; a nut is fixedly arranged on the position, which corresponds to the threaded rods, ofeach clamping plate; each threaded rod is in threaded connection with each nut and passes through the corresponding nut; a plurality of rolling slots are symmetrically formed in opposite side walls oftwo clamping plates between the two threaded rods; rolling balls which roll are arranged in the rolling slots; and ends, away from the slot bottoms of the rolling slots, of the rolling balls pass through the slot holes of the rolling slots and extend outwards. The service life of the steel wire rope is prolonged while the steel wire rope is prevented from dropping from the slot wheel.

Description

technical field [0001] The invention relates to the technical field of tower crane safety, in particular to an anti-detachment groove device for a steel wire rope of a tower crane trolley. Background technique [0002] The sheave is an important part of the lifting equipment, and it is widely used in the industrial or construction fields. The trolley of the tower crane is composed of multiple sheave structures. When the wrap angle in the center is large, the wire rope is easy to break away from the sheave groove. At this time, the stressed wire rope is squeezed and damaged, resulting in breakage, which is an important cause of wire rope breakage accidents. Contents of the invention [0003] The object of the present invention is to solve the problem in the prior art that the steel wire rope is easily detached from the sheave groove, and propose a wire rope detachment prevention groove device for a tower crane trolley. [0004] In order to achieve the above object, the pre...
