The present invention operation principle be：
This lifting mechanism is installed on bridge crane trolley frame, starts the motor 1 with braking function, Jing shaft couplings
Reducer input shaft 10 is driven to rotate after device 2, and after being slowed down by 2K-H types multi-stage planetary gear speed reducer 11, reducer output shaft
12 connect reel right end cap 6 by spline 14, so as to drive reel 5 to rotate around roll support seat 3 and bearing block 7, so as to reality
The function of existing raising weight.Lifting mechanism normally runs, and the start and stop that can pass through the motor 1 of braking function are realized with braking.
Once additionally, lifting mechanism drive system breaks down, the brake hard that reel 5 is realized in brake 8 can be passed through, prevent
Only there is car slipping accident in crane.
The invention has the beneficial effects as follows：
1st, Hoist Mechanism adopts multistage 2K-H types Planetary Gear Transmission, compares parallel-shaft gearbox, planetary gear
Decelerator small volume, large carrying capacity, working stability.
2nd, decelerator is built in reel, compact conformation, is effectively saved space, reduces lifting mechanism deadweight, is lifted
Liter weight is played, so as to reduce production and use cost.
3rd, lifting mechanism employs motor braking and reel mechanical braking double brake pattern, improves the reliability of lifting mechanism
Property, reduce security incident probability of happening.
4th, planetary reduction gear and motor keep concentric power transmission, and drive system radial load is less, lifting mechanism
Uniform force, rotor-support-foundation system contact fatigue crash rate is low, runs more steady.
5th, winding drum end cover adopts plate spoke structure, ventilation by forced draft to improve the cooling effect of built-in planetary reduction gear lubricating oil
Really, and reel can be reduced integrally conduct oneself with dignity.
