Concealed hoisting mechanism

Abstract

The invention relates to a concealed hoisting mechanism, which comprises a motor, a speed reduction device, a winding drum and a transmission shaft, wherein winding drum flanges are arranged at two sides of the winding drum; the winding drum and the winding drum flanges are connected through screw bolts, and are positioned in an arm frame; a motor is connected with the transmission shaft through the speed reduction device; a bearing and a bearing seat are arranged on installing plates at two sides of the arm frame; the bearing seat is connected with the installing plates through screw bolts; the transmission shaft is connected with the winding drum center for driving the winding drum to rotate; the motor and the speed reduction device use an integral right-angle speed reduction motor; themotor is arranged on an arm frame main chord rod at one side of the winding drum through screw bolts; a motor output shaft is a hollow shaft; a key groove is formed in the hollow shaft; a bulge matched with the key groove is arranged on the transmission shaft. The concealed hoisting mechanism has the advantages that the space in the arm frame is fully utilized; the structure design is compact; thelayout is reasonable; the light miniaturization of equipment is realized; the mounting and the dismounting are convenient; the hoisting mechanism and the arm frame can be integrally transported; thework efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting mechanisms, and in particular relates to a built-in hoisting mechanism suitable for electric pole and tower cranes. Background technique [0002] The hoisting mechanism, also called the hoisting mechanism, is the basic composition necessary for a crane to lift and lower objects. The hoisting mechanism is driven by the hoisting motor through the coupling through the hollow shaft of the reducer to rotate the reel, so that the wire rope / cable wound on the reel drives the hook device to rise or fall. In the structure of the existing lifting mechanism, there are three independent and side-by-side structures of the motor-reducer-reel, which increases the overall length of the lifting mechanism and the structure is not compact. And the traditional independent lifting mechanism used in lifting equipment such as electric poles and tower cranes is usually installed on the outside of the jib, which has a l...

In the structure of the existing lifting mechanism, there are three independent and side-by-side structures of the motor-reducer-reel, which increases the overall length of the lifting mechanism and the structure is not compact

And the traditional independent lifting mechanism used in lifting equipment such as electric poles and tower cranes is usually installed on the outside of the jib, which has a large independent volume and a large external space. It needs to be disassembled for transportation and is inconvenient to assemble. Disadvantages such as disassembly
