Abstract
The utility model relates to a kind of stop device Askania, comprises stop device body, and 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.After have employed said structure, have 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.
Description
Technical field
The utility model relates to the transportation device in mining industry collection, especially relates 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 problem to be solved in the utility model is to provide one can carry out safing stop device Askania of holding up traffic automatically.
The technical scheme in the invention for solving the technical problem is: 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 beneficial effects of the utility model are: 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 utility model.
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 utility model 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 utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong to the scope of technical solutions of the utility model.
