Embodiment Construction

[0016] The invention adopts the tensioning device to tighten the steel wire rope, and drives the steel wire rope to move through the wheel groove friction of the driving device.

[0017] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 Shown is the structural representation of the present invention.

[0019] The present invention provides a hoisting and lifting mechanism driven by expansion, which includes an expansion device 1, a driving device 2, a guide wheel 3, a rope reel 4, a hook group 5 and a fixed pulley group 6, and the fixed end is the driving device 2 , the tensioning end is the tensioning device 1.

[0020] The expansion device 1 is provided with a wheel shaft, a plurality of expansion wheels (the required number is determined by calculation, 4 pieces are shown in the figure), a bracket and a displacement device that moves sideways away from the driving end, and the expans...

Abstract

The invention discloses an expansion driving type hoisting and lifting mechanism, which comprises an expansion device, a driving device, a guide wheel, a rope unreeling reel, a lifting hook group and a fixed pulley group. The expansion device is provided with a wheel shaft, a plurality of expansion wheels, a bracket and a displacement device laterally moving back to a driving end, wherein the driving device comprises a gear motor, a driving wheel, a driving shaft, a bearing and a bearing support; a steel wire rope is crosswise wound between the driving device and the expansion device; one end of the steel wire rope, coming out from the driving device, is wound through the lifting hook group and the fixed pulley group and then fixed on a steel structure having a supporting effect; the other end of the steel wire rope, coming out from the expansion device, is fixedly wound on a rope containing reel through the guide wheel; and the driving wheel of the driving device and the rope containing reel simultaneously rotate anticlockwise or clockwise, so as to drive the lifting hook group to be lifted or descended. The mechanism is particularly suitable for occasions with large lifting heights and narrow installation spaces, has a simple structure, and is low in cost and beneficial to modular designs.

Description

technical field [0001] The invention relates to an expansion-driven winch lifting mechanism, which belongs to the technical field of hoisting machinery equipment. Background technique [0002] The hoisting mechanism is one of the important mechanisms of cranes and other mechanical equipment. The layout of the hoist of the commonly used hoisting mechanism is often restricted by the rope capacity of the drum, space installation requirements and many other aspects. The height (that is, the rope capacity) is limited, and the structure is complicated, and the manufacturing cost is high, which is not conducive to standardized and modular production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a winch lifting mechanism with simple structure and high lifting height in order to overcome the defects and deficiencies of the traditional lifting mechanism such as complex structure, high cost, large space occupation and li...
