Abstract

The invention discloses a chain hoist with a plurality of rows of chains. The chain hoist comprises an upper hook, a lower hook, a wall plate assembly, a main body mechanism and a driven wheel mechanism and is characterized in that the main body mechanism and the driven wheel mechanism are arranged on the wall plate assembly, a first axis connecting line is arranged between the axis of the main body mechanism and the axis of the driven wheel mechanism, a second axis connecting line is arranged between a hook body of upper hook and a hook body of the lower hook, and the inclined angle alpha between the first axis connecting line and the second axis connecting line ranges from 70 degrees to 90 degrees; the wall plate assembly comprises at least two wall plates; a driving lifting wheel of themain body mechanism and a driven moving wheel of the driven wheel mechanism are supported by the same wall plate. The chain hoist with the plurality of rows of chains is compact in space structure, small in size and low in weight.

Description

technical field

[0001] The invention belongs to the technical field of hoisting and traction devices, and in particular relates to a multi-row chain chain hoist. Background technique

[0002] At present, for multi-row chain chain hoists, the upper hook assembly includes a driven wheel structure, which is usually used in the following structural form: the upper hook covers the driven wheel assembly and is separated from the body, and is not on the same load-bearing body. There are two bifurcated extensions, one of which is connected to the main body mechanism with a gear shaft, and the other extension is connected to the driven wheel mechanism with a driven wheel and a driven shaft, because all the force is distributed to the On the two extensions, the two extensions need to bear greater gravity. Therefore, the weight of the upper hook and its extension is usually designed to be larger to withstand greater weight. At the same time, due to structural reasons, the distance betw...
