Light Electric Slewing Hook Set

Abstract

A light electric rotating lifting hook group comprises a gear motor, a pulley mechanism, a gear mechanism and a lifting hook mechanism, wherein the pulley mechanism comprises two groups of pulleys mounted at two ends of a pulley shaft; a pinion of the gear mechanism is fixedly connected onto the gear motor; a gear assembly integrates a friction block, an inner ring, bolt groups and a butterfly spring through press plates and is fixedly connected with a lifting hook handle through interference fit; according to the lifting hook mechanism, the upper end of the lifting hook handle sequentially penetrates through an adjusting sleeve on the upper surface of the gear assembly, a guide bearing, a support, a lifting hook beam and a thrust bearing to be bolted with a lifting hook nut, and shaft holes in two ends of each of two yoke plates are suspended on the lifting hook beam and the pulley shaft in a sleeving manner respectively; a lateral flange of the gear motor is bolted on the lifting hook beam and the support; and the pinion is meshed with a gear ring of the gear assembly. The light electric rotating lifting hook group has the benefits of simple and novel structure, convenience in manufacturing, low cost, convenience in binding force adjustment, small number of transmission chains, high efficiency, small mechanism sizes, light counterweight, high work precision and safe and reliable operation.

Description

technical field [0001] The invention relates to the field of hoisting and transportation, and relates to hoisting equipment, in particular to an electric rotary hook set. Background technique [0002] The electric rotary hook group of prior art is as Figure 1 to Figure 5 shown. Its main component is a flange-mounted geared motor (1 1 ), hook nuts (2 1 ), friction safety clutch (3 1 ), T-shaft (4 1 ), T-beam (5 1 ), gear shaft (6 1 ), gear (7 1 ), counterweight (8 1 ) and hooks (9 1 ) and other components. One end of the T-beam supports components such as geared motor, friction safety coupling and gear shaft, and the other end is balanced by a counterweight. The T-beam uses a pin shaft (10 1 ) hanging on the T-shaft (4 1 ) on the vertical axis side. image 3 is the front view of the T-axis, the T-axis consists of the horizontal axis (4 1 -1) and the vertical axis (4 1 -3) with bolts (4 1 -2) Bolted, horizontal shaft (4 1 -1) for hanging the pulley block; Fi...
