Description

Technical Field

[0001] The utility model belongs to the technical field of switch control, and particularly relates to an interlocking control device for a pneumatic air door and a pneumatic car stopper in a transportation roadway. Background Art

[0002] An air door is a facility for controlling air flow in an underground roadway, which facilitates the passage of pedestrians and transport vehicles. In order to effectively regulate and control the air volume in a coal mine underground, air doors are installed in inclined connecting roadways. An air-operated car stopper is installed in front of each air door to prevent the mine car from damaging the air door. The pneumatic air door and the pneumatic car stopper are controlled separately.

[0003] The existing interlocking control device for a pneumatic air door and a pneumatic car stopper in a coal mine inclined transportation roadway has several obvious defects: after the original car stopper in front of the underground air door is pneumatically opened, the operator then opens the air door through the pneumatic control box of the air door. After the vehicle passes, they are closed one by one. The operation procedure of the operator is cumbersome, and if the operator is negligent and fails to close the car stopper, it will cause a safety hazard that the car stopper is always open and may injure people due to the weight. Therefore, improvements are now made to the interlocking control device for the pneumatic air door and the pneumatic car stopper in the transportation roadway. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiment of the utility model provides an interlocking control device for a pneumatic air door and a pneumatic car stopper in a transportation roadway. Using this device for the interlock of the pneumatic air door and the pneumatic car stopper reduces the cumbersome operation procedures of the operator, so as to solve the problems raised in the above background art.

[0005] To achieve the above object, the utility model provides an interlocking control device for a pneumatic air door and a pneumatic car stopper in a transportation roadway, which includes an air source, a pneumatic two-way joint, a pneumatic two-position five-way valve, a throttle valve, an air door cylinder and a car stopper cylinder. The air source is connected in parallel with the pneumatic two-way joint and the pneumatic two-position five-way valve through an air pipe and a three-way joint;

[0006] The air source is connected in series with the air door cylinder and the car stopper cylinder.

[0007] Preferably, the pneumatic two-position five-way valve controls the opening and closing of the air door cylinder and the car stopper cylinder.

[0008] Preferably, the throttle valve is connected to the air door cylinder.

[0009] The interlocking control device for a pneumatic air door and a pneumatic car stopper in a transportation roadway proposed by the utility model can bring the following beneficial effects:

[0010] The compressed air from underground passes through the valve and the pneumatic combination unit to the pneumatic two-position five-way valve that controls the air door cylinder. When opening the air door, operate the pneumatic two-position five-way valve to make the air door cylinder act. Since the air pipes of the car stopper cylinder and the air door cylinder are in parallel, the car stopper cylinder acts simultaneously, and the car stopper opens. At this time, the air door has been opened, and the train can pass. Conversely, when closing the air door, the air door cylinder and the car stopper cylinder act simultaneously, the air door closes, and the car stopper also closes simultaneously, and the train cannot pass.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same solution or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0021] As Figures 1 to 2 shown, the embodiment of the present utility model provides an interlocking control device for a pneumatic air door and a pneumatic car stopper in a transportation roadway, which includes an air source 1, a pneumatic two-piece 2, a pneumatic two-position five-way valve 3, a throttle valve 4, an air door cylinder 5, and a car stopper cylinder 6. The air source 1 is connected in parallel with the pneumatic two-piece 2 and the pneumatic two-position five-way valve 3 through an air pipe and a tee. When the air door is opened, the air door cylinder 5 and the car stopper cylinder 6 act simultaneously, the air door opens, and the car stopper also opens simultaneously. When the air door is closed, the air door cylinder 5 and the car stopper cylinder 6 act simultaneously, the air door closes, and the car stopper also closes simultaneously.

[0022] As Figure 1 and Figure 2As shown in the figure, the air door cylinder 5 and the car stopper cylinder 6 are in series with the air source 1. The five ventilation pipelines of the two-position five-way reversing valve are respectively connected to the air source 1, and are connected to the two intake air pipes on the right side of the air door cylinder 5 and the car stopper cylinder 6, and cooperate with the two exhaust air pipes on the left side to exhaust air. The pneumatic two-position five-way valve 3 exhausts air from port 5 to close the air door and the car stopper cylinder 6.

[0023] As Figure 1 and Figure 2 shown in the figure, the pneumatic two-position five-way valve 3 controls the opening and closing of the air door cylinder 5 and the car stopper cylinder 6.

[0024] As Figure 1 and Figure 2 shown in the figure, the throttle valve 4 is connected to the air door cylinder 5. The compressed air from the underground passes through the valve and the pneumatic combination unit 2 to the pneumatic two-position five-way valve that controls the air door cylinder 5. When opening the air door, operate the pneumatic two-position five-way valve to make the air door cylinder 5 act.

[0025] Working principle:

[0026] The compressed air from the underground passes through the valve and the pneumatic combination unit 2 to the pneumatic two-position five-way valve that controls the air door cylinder 5. When opening the air door, operate the pneumatic two-position five-way valve to make the air door cylinder 5 act. Since the air pipes of the car stopper cylinder 6 and the air door cylinder 5 are in parallel, the car stopper cylinder 6 acts simultaneously, and the car stopper opens. At this time, the air door has been opened, and the train can pass. Conversely, when closing the air door, the air door cylinder 5 and the car stopper cylinder 6 act simultaneously, the air door closes, and the car stopper also closes simultaneously, and the train cannot pass.
