The selecting valve is connected to the air door cylinder and the car stop cylinder and controls the same to open and close. Compared with the prior art, the air door and car stop interlock control device has the advantages of simple structure, convenience of use and ingenious design, labor intensity of workers is reduced, safe operation and safety of operators are guaranteed, and the device is high in practicality, broad in adaptable range and easy to promote.
Description
Technical field
The utility model relates to coal mine roadway switch gate control technology field, relates in particular to a kind of simple in structure, air door and car lug interlock control apparatus.
Background technology
Under coal mine, in the motor vehicles passage in haulage drift, be all provided with air door at present, a car lug is installed before per pass air door.Owing to there being battery truck operation in connection roadway, before air door, original car lug is to have manually to pull, the difficulty that not only operates, and because air door is automatic shutter, sometimes when battery truck runs to air door centre, air door is just closed automatically, at this moment just need to have an other people that air door is pulled open.When battery truck is by air door like this, just need a people to open the other people of air door and pull car lug, simultaneously because the space of haulage drift is narrow, battery truck during by air door operating personnel stand in train side operation air door and car lug exists potential safety hazard.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, air door and the car lug interlock control apparatus that can eliminate shaft voltage is provided.
The technical solution of the utility model is, a kind of air door and car lug interlock control apparatus, comprise air line, air door cylinder, car lug cylinder, this air door cylinder, car lug cylinder are by the above-mentioned air line of airduct rear series connection parallel with one another, described air line comprises that pressure ventilation pipe, series connection are arranged on the valve on pressure ventilation pipe and select valve, and this selector valve gate control connects the keying of above-mentioned air door cylinder, car lug cylinder.
In technique scheme, select valve for controlling the keying of air door cylinder, car lug cylinder, in the time that needs are opened air door, selector switch control pressure ventilation pipe is interior from air door cylinder and car lug cylinder one side air intake, opposite side air-out, just can realize air door and car lug and open simultaneously or close, alleviate staff's labour intensity, guarantee staff's safety.
As preferably, described selection valve is switch valve with two-position and five-pass, and five air pipelines of this switch valve with two-position and five-pass connect respectively pressure ventilation pipe, connect two airducts of air door cylinder and car lug cylinder both sides, be used in conjunction with airduct and two stacks that can exhaust.In this technical scheme, adopt the two-position five-way valve that can manually control, adopt pneumatic control principle, effectively realize the interlocked control of car lug and air door.
In sum, the beneficial effect that the utility model compared with prior art produced is:
The features such as that air door of the present utility model and car lug interlock control apparatus have is simple in structure, easy to use, be skillfully constructed, stable performance, conducting by hand-operated valve control two-position five-way valve makes cylinder moving with closing, then drive the power transmission shaft of car lug to make it to carry out elevating movement, effectively improve the time that train passes through, alleviate staff's labour intensity, guaranteed safe operation and operating personnel's safety, practical, applied widely, be easy to promote.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Mark in accompanying drawing represents respectively:
1, air line, 1.1, pressure ventilation pipe, 1.2, valve, 1.3, select valve, 2, air door cylinder, 3, car lug cylinder, 4, airduct, 5, stack.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of a kind of air door of the present utility model and car lug interlock control apparatus is described in detail below.
As shown in Figure 1, a kind of air door shown in the utility model and car lug interlock control apparatus, comprise air line 1, air door cylinder 2, car lug cylinder 3, this air door cylinder 2, car lug cylinder 3 are by the above-mentioned air line 1 of airduct rear series connection parallel with one another, described air line 1 comprises that pressure ventilation pipe 1.1, series connection are arranged on the valve 1.2 on pressure ventilation pipe 1.1 and select valve 1.3, the keying of the above-mentioned air door cylinder 2 of this selection valve 1.3 control connection, car lug cylinder 3.
Described selection valve 1.3 is switch valve with two-position and five-pass, and five air pipelines of this switch valve with two-position and five-pass connect respectively pressure ventilation pipe 1.1, connect two airducts 4 of air door cylinder 2 and car lug cylinder 3 both sides, be used in conjunction with airduct 4 and two stacks 5 that can exhaust.
The source of the gas of this device hand control valve, from the unlatching source of air door cylinder 2, only has air door cylinder 2 to obtain wind regime, and when door opening, hand control valve obtains source of the gas and could control two-position five-way valve, thereby has realized the interlocked control of car lug and air door.
Pressure wind from down-hole arrives through valve 1.2 switch valve with two-position and five-pass of controlling air door cylinder 2, in the time opening air door, operation switch valve with two-position and five-pass moves air door cylinder 2, because car lug cylinder 3 and the airduct 4 of air door cylinder 2 are in parallel, so car lug cylinder 3 moves simultaneously, car lug falls, and at this moment air door is opened, and train can pass through.Otherwise while closing air door, air door cylinder 2 moves with car lug cylinder 3 simultaneously, and air door is closed, and car lug is also closed simultaneously, and train can not pass through.
Except the technical characterictic described in manual, be the known technology of those skilled in the art.
