Description
Technical field
The present invention relates to a kind of synchronous device, be specifically related to a kind of mechanical synchronizer mechanically solving the hydraulic wireline winch of hydrostatic drive stationary problem.
Background technology
According to current hydraulic technique, simple rely on hydraulic efficiency pressure system itself to realize two hydraulic wireline winchs synchronously to acquire a certain degree of difficulty or uneconomic, need to adopt other method to ensure two hydraulic wireline winchs steadily synchronous in operation process.
Summary of the invention
The technical problem to be solved in the present invention relies on merely hydraulic efficiency pressure system itself to realize two hydraulic wireline winchs synchronously to acquire a certain degree of difficulty or uneconomical, a kind of restriction that can overcome hydraulic efficiency pressure system is provided, mechanically solve hydrostatic drive stationary problem, reduce the mechanical synchronizer of the hydraulic wireline winch of device systems cost.
For achieving the above object, the present invention adopts following technical proposals: a kind of mechanical synchronizer of hydraulic wireline winch, comprise fixed frame and with a left side, the left side wire rope fixing device of the steel cable winding system end connection of right hydraulic wireline winch elevator and right side wire rope fixing device, left, right hydraulic wireline winch adopts same solenoid directional control valve centralized oil supply, the steel cable winding system of hydraulic wireline winch elevator drives middle axis of guide motion, the middle axis of guide drives the flexible of disc spring compression set by baffle plate, the flexible change solenoid directional control valve central lubricating system hydraulic oil of disc spring compression set flows to the side that pressure is little, reach the stress equalization of synchronous device both sides.
The described middle axis of guide is provided with axially directed sliding sleeve.
Structure of the present invention is simple, dependable performance, manufactures, uses, easy to maintenance; Substitute hydraulic pressure simultaneous techniques, comparatively economical; Mechanical efficiency is higher, not by the impact of ambient temperature; To the impact of hydraulic wireline winch hydraulic efficiency pressure system, there is shock attenuation result.

Fig. 3 is hydraulic schematic diagram of the present invention.
Fig. 4 is using state structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the present invention includes fixed frame 57 and with a left side, the left side wire rope fixing device 51 of the steel cable winding system 42 end connection of right hydraulic wireline winch elevator and right side wire rope fixing device 56, left, right hydraulic wireline winch adopts same solenoid directional control valve centralized oil supply, the steel cable winding system 42 of hydraulic wireline winch elevator 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 side flowing little to pressure of the flexible change solenoid directional control valve central lubricating system hydraulic oil of disc spring compression set 54, 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 4, 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 3, 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.
