Abstract
The utility model relates to a constant force rotary lifter. Through altering the number and the distribution structure of the reel groups in a spiral spring mechanism and adopting a step-by-step rotary lifting mode, the lifting force generated by a spiral spring is similar to the weight of a device to be maintained so as to ensure the force for lifting the device to be maintained. The utility model not only increases the weight of the device to be maintained but also reduces the auxiliary force in manual operation, greatly reduces the impact to the disassembled parts in the device maintenance and improves the positioning precision of a mobile component. Due to the adoption of the traction force generated by the spiral spring assembly, the utility model does not have any electric device. Thus, the utility model has the advantages of simple structure, convenient maintenance, low cost and easy installation and use.

The specific embodiment
Constant force rotation lifting apparatus described in the utility model, quantity and distribution situation according to reel and wind spring in the device, utilize the mode of rotating lifting step by step, produce with by the identical or close convergent force of docking facility weight, to reach safety, convenient, labour-saving purpose, wherein, reel is fixed on the wind spring support, its weight during not to docking facility the convergent force of wind spring exert an influence.
The specific embodiment of the present utility model such as Fig. 5, a kind of constant force rotation lifting apparatus comprises wind spring mechanism, lifting mechanism, fixed support 5 and connecting panel 8.Wherein lifting mechanism comprises guide rail 2, slide block 3, link 4 and turning unit 9; Wind spring mechanism comprises two groups of reels 1 in parallel and wind spring 6, is symmetrically distributed along guide rail 2 axis directions, and wherein every group comprises three wind springs 6, connecting panel 8 and order three fixing reels 1 that stagger from top to bottom.One end of each wind spring 6 is fixed on the reel 1, the other end links to each other with connecting panel 8, keep connecting panel 8 vertical with lifting mechanism, connecting panel 8 is fixed on the link 4 of lifting mechanism, link 4 is fixing with slide block 3, slide block 3 is enclosed within on the guide rail 2, and the outer end of link 4 and turning unit 9 join; Wind spring mechanism is separately fixed on the fixed support 5 by guide rail 2 by wind spring support 7, lifting mechanism.
In the work, be fixed on the turning unit 9 by the docking facility parts, because the convergent force adjusted of wind spring 6 is by the weight of Awaiting Parts, so only need artificial strength by the very little lifting initial stage, just but the lifting Awaiting Parts avoids producing impulsive force simultaneously, influences the service life of parts, by the mobile Awaiting Parts of the rotation of turning unit, satisfy maintenance time space needs.After maintenance is finished, the rotation Awaiting Parts, light downwards the pressure resets Awaiting Parts, because used strength only plays the startup effect when descending, so downward impulsive force is little, control easily, not fragile Awaiting Parts, the utility model are in maintenance process, and operating process is simple, convenient, be easy to use.
