Detailed description of the invention
As shown in Figure 1 to Figure 3, the top pulleys group 41 that the present invention includes suspender frame 46 and be arranged on door frame 2, also comprise the running block 44 with top pulleys group 41 transmission link, connect the steel cable winding system 42 of top pulleys group 41 and running block 44 and drive the hydraulic wireline winch 45 of steel cable winding system 42 elevator, described running block 44 is arranged in suspender frame 46.
Described hydraulic wireline winch 45 is driven by the electric and hydraulic efficiency pressure system 43 be arranged on the crossbeam of special hanger.
Described steel cable winding system 42 comprises left steel cable winding system 421 and right steel cable winding system 422.
Described hydraulic wireline winch 45 comprises left hydraulic wireline winch 451 and right hydraulic wireline winch 452.
Synchronous device 5 is provided with between described left steel cable winding system 421 and right steel cable winding system 422.
As shown in Figures 4 to 7, described synchronous device 5 comprise fixed frame 57 and with a left side, the left side wire rope fixing device 51 that right hydraulic wireline winch hoisting rope winding system 42 end connects and right side wire rope fixing device 56, left, right hydraulic wireline winch adopts same solenoid directional control valve centralized oil supply, hydraulic wireline winch hoisting rope winding system 42 drives the middle axis of guide 52 to move, the middle axis of guide 52 drives the flexible of disc spring compression set 54 by baffle plate 53, the flexible solenoid directional control valve central lubricating system hydraulic oil that makes of disc spring compression set 54 flows to the side that pressure is little, reach the stress equalization of synchronous device both sides.The described middle axis of guide 52 is provided with axially directed sliding sleeve 55.During work, as shown in Figure 7, the fixed frame 57 of this synchronous device is welded on same foundation frame 50 with left hydraulic wireline winch 451 and right hydraulic wireline winch 452.This mechanical synchronizer is arranged on the connection end of two hydraulic wireline winch hoisting rope winding systems, suppose when left hydraulic wireline winch 451 reels too fast, the middle axis of guide 52 will move to the left, compression disc spring compression set 54 produces resistance to the right, left side lineoutofservice signal pull is caused to increase, along with the increase of disc spring amount of compression, resistance increases thereupon, namely when left side lineoutofservice signal pull increases to a certain degree, as shown in Figure 6, because two hydraulic wireline winchs adopt same solenoid directional control valve 453 centralized oil supply, A is hydraulic efficiency power unit, both charge oil pressures are same in theory, after this state of equilibrium is broken, left hydraulic wireline winch 451 hydraulic system pressure increases, according to the feature of hydraulic oil self, liquid is caused to flow to right hydraulic wireline winch 452(right atrial pressure less) flowing, left hydraulic wireline winch 451 hydraulic system pressure will reduce, until two hydraulic wireline winch hydraulic efficiency pressure system charge oil pressures are balanced, thus reach left, the object of right both sides lineoutofservice signal pull equilibrium, overcome the too much situation that to be reeled by Wound steel rope because a side draw is excessive, realizing winch elevator is wound around synchronous.Just can produce larger resistance because combination disk spring amount of compression is very little, buffering damping capaicty is strong, and this dynamic mechanical synchronization technology is easy to the synchronous winding performance of guarantee two hydraulic wireline winch.
As shown in Figure 1, the present invention is arranged on door frame 2 by top pulleys group 41, by independently electrically and hydraulic efficiency pressure system 43 drive left hydraulic wireline winch 451 and right hydraulic wireline winch 452 action, left hydraulic wireline winch 451 and right hydraulic wireline winch 452 keep synchronization action under the effect of synchronous device 5, through the winding system of top pulleys group 41, steel cable winding system 42 and running block 44 composition, drive the ascending, descending operation of special hanger.
