Multi-storied garage lift platform Power Drive Unit
Technical field
The present invention relates to parking systems technical field.
Background technology
The power of existing machinery formula multi-storied garage lifting platform is made up of multiple power unit, is easy to cause lifting asynchronous; If one of them goes wrong, platform inclination is often caused to cause the accident.Reliability and safety is poor.
Summary of the invention
The technical problem to be solved in the present invention is the deficiency overcoming above-mentioned prior art, provide a kind of multi-storied garage lift platform Power Drive Unit, Power Drive Unit of the present invention has good synchronism, can substantially increase the reliability of lifting platform, stability and safety, its structure is simple, easy to use.Be specially adapted in the jacking system of macromechanical multi-storied garage platform.
Technical scheme of the present invention is: a kind of multi-storied garage lift platform Power Drive Unit, comprise motor, main gear reducer, it is characterized in that motor is connected with the first power shaft of main gear reducer by first clutch, the output shaft of main gear reducer is connected with vertical shaft type large bevel gear, vertical shaft type large bevel gear engages with four uniform cone pinions, four cone pinions are connected with 4 Synchronous Transmission axles in crossing distribution respectively, every root power transmission shaft is all connected with the power shaft of the worm-gear speed reducer with auto-lock function, the output shaft of worm-gear speed reducer is all connected with lift platform by sprocket wheel and chain.
Described main gear reducer, be provided with motor for subsequent use better, motor for subsequent use is connected with the second power shaft of main gear reducer by second clutch.
Described main gear reducer is that hardened face gear reductor is better.
Described sprocket wheel is double chain wheel or 4 sprocket wheels, better.
Described first clutch and second clutch are clutch-brake, better.
The magnetic powder clutched brake of described clutch-brake, better.
Good effect of the present invention is significant: the deficiency overcoming above-mentioned prior art, and Power Drive Unit of the present invention has good synchronism, can substantially increase the reliability of lifting platform, stability and safety, and its structure is simple, easy to use.Be specially adapted in the jacking system of macromechanical multi-storied garage platform.
Be described further below in conjunction with embodiment and accompanying drawing, but not as to restriction of the present invention.

Detailed description of the invention
See Fig. 1, Fig. 2, one this multi-storied garage lift platform Power Drive Unit, comprise motor 8, reductor 7, it is characterized in that motor 8 is connected with the first power shaft of reductor 7 by first clutch device 10, the output shaft of reductor 7 is connected with vertical shaft type large bevel gear 6, vertical shaft type large bevel gear 6 engages with four uniform cone pinions 5, four cone pinions 5 are connected with 4 Synchronous Transmission axles 4 in crossing distribution respectively, every root power transmission shaft 4 is all connected with the power shaft of the worm-gear speed reducer 3 with auto-lock function, the output shaft of worm-gear speed reducer 3 is all connected with lift platform by sprocket wheel 2 and chain 1.Described reductor 7 is provided with motor 9 for subsequent use, and motor 9 for subsequent use is connected with the second power shaft by second clutch 11.Described first clutch 10 and the second clutch-brake 11 are magnetic powder clutched brake, possess power and engage two item function with stopping brake.Described sprocket wheel 2 is double chain wheel, and balance is good, stressed good.Main gear reducer adopts the hardened face gear reductor with 2 power shafts better.Other reductor also can be used.
During work, main gear reducer 7 outputting power is to vertical shaft type large bevel gear 6, vertical shaft type large bevel gear 6 engages with four uniform cone pinions 5, power is evenly distributed on the Synchronous Transmission axle 4 in cross distribution, power transmission shaft 4 has power input belt the worm-gear speed reducer 3 of auto-lock function again, output on double chain wheel 2 and chain 1 again, chain 1 and multi-storied garage platform are connected thus drive platform to form synchronization lifting and move.Motor 8 and motor for subsequent use 9 carry out powershift by control system.System is that power drives multi-storied garage lifting platform by uniform four positions; and by the self-lock protection of worm-gear speed reducer 3 implementation platform that possesses auto-lock function, and ensured accurate location and the safety of platform by the effective brake of first clutch 10 and second clutch 11.
