The working process of winch of the present invention mainly is that power hoists and power descends, and details are as follows:
Process hoists:
Winch power hoists in the process, and the power of external motor is delivered to planetary reducer 5 by power input female splined shaft 25, input shaft 3, increases by planetary reducer 5 reductions of speed and turns round 6 rotations of rear drive reel, realizes that the power of winch hoists.In this process, because power input female splined shaft 25 is the direction rotations that hoist along overdrive clutch assembly 15, overdrive clutch assembly 15 is in released state, be that power input female splined shaft 25 can freely rotate relative to driven gear 22, do not brake friction force between the moving plate 14 so do not need to remove internal tooth braking stator 13 and external tooth, namely winch is the brake portion that does not need to open normally off in power hoists process.
If in a ponderomotive force hoists process, motor power is stopped, the gravity of weight is by reel 6, planetary reducer 5, input shaft 3 reacts on power input female splined shaft 25, its descent direction along overdrive clutch assembly 15 is rotated, power input this moment female splined shaft 25 can can't be rotated by locking, and still be in closure state owing to brake portion this moment, and weight can't move along descent direction, thereby played the safety effect that prevents weight slide hook.
The decline process:
In the elevator decline process, because power input female splined shaft 25 moving by the overriding clutch locking along descent direction, must compress spring this moment by the external hydraulic pressure of drg control port, remove the friction force between internal tooth braking stator 13 and the external tooth braking moving plate 14, make overdrive clutch assembly 15 drive internal tooth braking stator 13 and rotate along descent direction together, thereby the power of realizing winch descends.
If in playing ponderomotive force decline process, motor power is stopped, on the one hand power input female splined shaft 25 along the rotation meeting of descent direction by locking, on the other hand because the pressure of drg control port is released, spring 18 can can't relatively rotate power input female splined shaft 25 with driven gear 22 at elastic force, play preventing that weight from slipping the safety effect of hook to moving plate and stator force together.
The present invention is owing to only need open drg in power decline process, and power decline process only needs a lower pressure just can realize, thereby do not need reducing valve of special configuration to obtain low hydraulic coupling, can directly use the hydraulic coupling in the main hydraulic system to open drg, the system of winch is simpler, and fault rate reduces greatly.
Although in conjunction with the embodiments the present invention is described in detail; but those skilled in the art are with being to be understood that; the present invention is not limited only to specific embodiment; on the contrary; in the various corrections that do not exceed the application's spirit and essence, distortion and replacement all drop among the application's the protection domain.
