Problems solved by technology

[0002] Although the traditional hoisting mechanism can meet the working requirements of lifting loads, it cannot meet the function of lifting loads when the system is powered off; nor can it realize that when a wire rope suddenly breaks, it will still not be damaged. impact, and can continue to work and lift loads; and the traditional lifting mechanism does not have a component failure monitoring device, so that the driver and ground staff do not understand the working status of each component in the lifting mechanism, and cannot take preventive measures in advance
Therefore, the safety of the traditional lifting mechanism is low, and it is easy to cause failure to cause downtime and safety accidents

Embodiment Construction

[0025] Such as figure 1 and figure 2 As shown, the present invention consists of a lifting drive system 1, a speed measuring device 2, a wire rope winding monitoring device 3, a balance beam device 4, a fixed pulley block assembly 5, a clutch device 6, a manual mechanism 7, an overspeed protection device 8, and a broken shaft protection device 9. Composed of a fire-off limiting device 10, a lifting limiting device 11, a hook pulley block 12, a wire rope 13 and other accessories.

[0026] image 3 The middle lifting driving system 1 is composed of a motor 1-1, a speed reducer 1-2, a brake 1-3, a universal joint 1-4, a reel group 1-5 and the like.

[0027] The two motors are rigidly connected through the universal coupling 1-4, which ensures the synchronous rotation of the motors. The motor 1-1 drives the reel group 1-5 to rotate through the reducer 1-2. One end of two steel wire ropes 13 is fixed on the reel set 1-5, and the other end passes through the hook pulley set 12 ...

Abstract

The invention discloses a hoisting mechanism for a crane, which is applied to various bridge cranes, gantry cranes and the other devices relative to hoisting job category. The hoisting mechanism consists of a hoisting driving system, a speed measuring device, a wire rope winding monitoring device, a beam balancing device, a crown block assembly, a clutch device, a hand mechanism, an over speed protector, a shaft breaking protector, a flameout limit device, a hoisting limit device, a hook pulley assembly, a wire rope and the other accessories. The hoisting mechanism eliminates the bad effects which are caused by the errors such as hoisting wire rope breaking, hoisting over speed, hoisting over journey, hoisting desynchrony, mechanism switching off, etc. The hoisting mechanism monitors various fault conditions in real time, thereby work is safer when the crane hoists load.

Description

technical field [0001] The invention relates to a hoisting machine, especially a hoisting mechanism of a crane or other hoisting equipment. Background technique [0002] Although the traditional hoisting mechanism can meet the working requirements of lifting loads, it cannot meet the function of lifting loads when the system is powered off; nor can it realize that when a wire rope suddenly breaks, it will still not be damaged. And the traditional lifting mechanism does not have a component failure monitoring device, so that the driver and ground staff do not know the working status of each component in the lifting mechanism, and cannot take preventive measures in advance. Therefore, the safety of the traditional hoisting mechanism is low, and it is easy to cause failures to cause downtime and safety accidents. Contents of the invention [0003] The present invention fully considers the unsafe factors existing in the working process of the traditional lifting mechanism and...
