Abstract
The invention discloses a mechanical synchronizer of hydraulic winches. The mechanical synchronizer of the hydraulic winches utilizes a mechanical method to solve the synchronization problem of hydraulic transmission and aims at solving the technical problem that purely utilizing a hydraulic system to achieve the synchronization of the two hydraulic winches is difficult or uneconomical. The mechanical synchronizer of the hydraulic winches comprises a fixing frame, a left steel wire rope fixing device and a right steel wire rope fixing device, the left steel wire rope fixing device and the right steel wire rope fixing device are connected with the tail ends of steel wire rope enwinding systems of hoisting of the hydraulic winches, the left hydraulic winch and the right hydraulic winch achieve centralized oil supply through the same electromagnetic directional valve, the steel wire rope enwinding systems drive middle guide shafts to move, the middle guide shafts drives a disc spring compression device to extend and retract through baffles, the extension of the disc spring compression device changes the electromagnetic directional valve to enable hydraulic oil of a centralized oil supply system to flow to one side with smaller pressure. The mechanical synchronizer of the hydraulic winches is simple in structure, reliable in performance, convenient to manufacture, use and maintain, relatively economical, and is high in mechanical efficiency.
Description
Technical field
The present invention relates to a kind of synchronous device, be specifically related to a kind of mechanical synchronizer that solves the hydraulic wireline winch of hydrostatic drive stationary problem with mechanical means.
Background technology
According to current hydraulic technique, rely on merely hydraulic efficiency pressure system itself to realize that two hydraulic wireline winchs synchronously acquire a certain degree of difficulty or uneconomic, need to adopt other method to guarantee that two hydraulic wireline winchs are steadily synchronous in operation process.
Summary of the invention
The technical problem to be solved in the present invention is to rely on merely hydraulic efficiency pressure system itself to realize that two hydraulic wireline winchs synchronously acquire a certain degree of difficulty or uneconomical, a kind of restriction that can overcome hydraulic efficiency pressure system is provided, with mechanical means, 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, left side wire rope fixing device and right side wire rope fixing device that the steel cable winding system end of right hydraulic wireline winch elevator connects, left, right hydraulic wireline winch adopts same solenoid directional control valve centralized oil supply, axis of guide motion in the middle of the steel cable winding system of hydraulic wireline winch elevator drives, the middle axis of guide drives the flexible of dish spring compression set by baffle plate, the flexible change solenoid directional control valve central lubricating system hydraulic oil of dish spring compression set is to the little side flow of pressure, reach the stress equalization of synchronous device both sides.
On the described middle axis of guide, be provided with axially directed sliding sleeve.
The present invention is simple in structure, dependable performance, manufacture, use, easy to maintenance; Substitute hydraulic pressure simultaneous techniques, comparatively economical; Mechanical efficiency is higher, is not subject to the impact of ambient temperature; Impact to hydraulic wireline winch hydraulic efficiency pressure system has shock attenuation result.

The specific embodiment
As shown in Figure 1 to Figure 3, the present invention includes fixed frame 57 and with a left side, left side wire rope fixing device 51 and right side wire rope fixing device 56 that steel cable winding system 42 ends of right hydraulic wireline winch elevator connect, left, right hydraulic wireline winch adopts same solenoid directional control valve centralized oil supply, the axis of guide 52 motions in the middle of the steel cable winding system 42 of hydraulic wireline winch elevator drives, the middle axis of guide 52 drives the flexible of dish spring compression set 54 by baffle plate 53, the flexible change solenoid directional control valve central lubricating system hydraulic oil of dish spring compression set 54 to the little side flow of pressure, reach the stress equalization of synchronous device both sides.
On the described middle axis of guide 52, be 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 to reel when too fast when left hydraulic wireline winch 451, the middle axis of guide 52 will move to the left, the resistance that compact disc spring compression set 54 produces to the right, cause left side lineoutofservice signal pull to increase, increase along with dish spring amount of compression, resistance increases thereupon, 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 supplies, 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 pressures increase, according to the feature of hydraulic oil self, cause liquid to flow to right hydraulic wireline winch 452(right atrial pressure less) flow, left hydraulic wireline winch 451 hydraulic system pressures will reduce, until two hydraulic wireline winch hydraulic efficiency pressure system charge oil pressures are balanced, thereby reach left, the object of right both sides lineoutofservice signal pull equilibrium, overcome because a side draw is crossed senior general's Wound steel rope too much situation of reeling, realizing winch elevator is wound around synchronous.Because combination disk spring amount of compression is very little, just can produce larger resistance, buffering damping capaicty is strong, and this dynamic mechanical synchronization technology is easy to guarantee the synchronous coiling performance of two hydraulic wireline winchs.
