Abstract
The invention relates to a hydraulic automatic control device of a car stopper. The device comprises a car stopper body, wherein the car stopper body is connected with a hydraulic cylinder through a connecting device; an oil pipe on the hydraulic cylinder is connected with two oil inlets in the upper side of a three-position four-way electromagnetic reversing valve; an oil inlet in the lower side of the three-position four-way electromagnetic reversing valve is communicated with an oil tank through a one-way valve, a hydraulic motor and a filter in sequence; and another oil inlet is communicated with the oil tank through a cooler. After the structure is adopted, multiple automatic control functions including car stop are realized, so that a winch control system is operated more safely and reliably, the performance is more stable, and the device has comprehensive promotion and application prospect in the mine inclined shaft rail lifting field.
Description
Technical field
The present invention relates to the transportation device in mining industry collection, especially relate to a kind of stop device Askania.
Background technology
In the hydraulic wireline winch in colliery, need to install stop device to control position and the motion of winch, existing stop device adopts manual form usually, when winch reaches desired location, pull stop device, realize the object of holding up traffic, or realized by electronic mode, this mode, in use, due to manual operation, often to slip, thus cause safety misadventure, not only can not ensure the safety of workman, but also have impact on its production efficiency, improve productive costs.
Summary of the invention
Technical matters to be solved by this invention is to provide one can carry out safing stop device Askania of holding up traffic automatically.
The present invention solves the technical scheme that its technical matters takes: a kind of stop device Askania, comprise stop device body, described stop device body is connected with hydraulic actuating cylinder by connecting device, and on described hydraulic actuating cylinder, oil pipe is connected with the oil inlet of two on the upside of three-position four-way electromagnetic directional valve; An oil inlet of the downside of described three-position four-way electromagnetic directional valve is communicated with fuel tank by check valve, HM Hydraulic Motor and filter successively, and another oil inlet is communicated with fuel tank by cooling vessel.
Concrete further, described three-position four-way electromagnetic directional valve is controlled by PLC.
Concrete further, described automatic control device comprises the counting machine of a control end and control end inside, and control end is connected with three-position four-way electromagnetic directional valve.
The invention has the beneficial effects as follows: after have employed said structure, there is the multinomial automatic control function of holding up traffic, make Winch control system safe in operation, reliable more, performance is more stable, has the prospect popularizing application in an all-round way in slope lifting track field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, stop device body; 2, connecting device; 3, hydraulic actuating cylinder; 4, three-position four-way electromagnetic directional valve; 5, check valve; 6, HM Hydraulic Motor; 7, filter; 8, cooling vessel; 9, fuel tank.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is explained in detail.
A stop device Askania as shown in Figure 1, comprises stop device body 1, and described stop device body 1 is connected with hydraulic actuating cylinder 3 by connecting device 2, and on described hydraulic actuating cylinder 3, oil pipe is connected with two oil inlets on the upside of three-position four-way electromagnetic directional valve 4; An oil inlet of the downside of described three-position four-way electromagnetic directional valve 4 is communicated with fuel tank 9 by check valve 5, HM Hydraulic Motor 6 and filter 7 successively, and another oil inlet is communicated with fuel tank 9 by cooling vessel 8; Described three-position four-way electromagnetic directional valve 4 is controlled by PLC; Described automatic control device comprises the counting machine of a control end and control end inside, and control end is connected with three-position four-way electromagnetic directional valve 4.
When mine car is descending, hydraulic wireline winch Obstruct apparatus is standby, now PLC master control power connection, winch starts to start, when mine car runs to PLC internal counter first setting value, namely send the signal of " loose rail ", and the HM Hydraulic Motor 6 of stop device device starts to start, the electromagnet (Y2) of three-position four-way electromagnetic directional valve 4 obtains electric, so three-position four-way electromagnetic directional valve 4 is moved to the left simultaneously.At this moment, fluid flows into from the right chamber of hydraulic actuating cylinder 3, and left chamber is flowed out.Piston rod drives stop device body 1, just achieves the action of " loose rail ", thus stop device body 1 is in unclamp track condition, and mine car is let pass.When mine car runs arrival second setting value, namely send and embrace rail signal, HM Hydraulic Motor starts to start, and three-position four-way electromagnetic directional valve 4 electromagnet (Y1) obtains electric simultaneously, and (Y2) power-off, so three-position four-way electromagnetic directional valve 4 moves right.
Now, fluid flows into from the left chamber of hydraulic actuating cylinder 3, and right chamber is flowed out.Piston rod just drives stop device body 1 to realize the action of " embracing rail ", makes stop device body 1 be in the state of holding track tightly.When mine car is up, its program and action and descending time just on the contrary.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
