Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to an underground air door and vehicle blocking joint control device for a coal mine. Background Art

[0002] When mine transport vehicles pass through the dampers, they are easily affected by many factors such as inertial impact, brake failure, on-site light and visual environment, driver's lack of concentration, tunnel slope, slippery floor, etc., which may cause vehicle collision with the damper. In mild cases, the damper, vehicle and other equipment are damaged, and in severe cases, the normal transportation and production of the mine are directly affected. Once the damper at the main air inlet and return point is hit, it may even cause the ventilation system of the entire mine to be disordered, thereby causing secondary disasters such as excessive gas and suffocation of personnel due to lack of oxygen. In the daily management process, there is a great safety risk. For this reason, it is necessary to equip the damper with an anti-collision vehicle blocking device or system.

[0003] The existing car blocking devices mainly include: mechanical linkage anti-collision car blockers, which have complex structures, occupy large spaces, have high failure rates, and are partially connected to the damper, which can only reduce the degree of impact damage but cannot completely eliminate damage; electro-hydraulic anti-collision systems, which have complex components and require the addition of electrical equipment and control systems. They must consider both explosion-proof issues and compatibility with existing equipment, and have complex structures, high failure rates, and require many modifications and changes, making them difficult to promote and apply on a large scale. Therefore, it is necessary to improve and optimize the existing devices. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] like Figure 1 As shown, an embodiment of the utility model provides a coal mine underground damper and vehicle blocking joint control device, comprising: a damper 11, which can be opened and closed in a tunnel; a first pneumatic part 12, which is connected to a compressed air power source outside the tunnel, and the first pneumatic part 12 drives the damper 11 to open and close; a vehicle blocking device 21, which can be opened and closed at a set position in front of the damper 11, and the vehicle blocking device 21 is used to block or avoid vehicles that are about to pass through the damper 11; a second pneumatic part 22, which is connected to the compressed air power source, and the second pneumatic part 22 drives the vehicle blocking device 21 to open and close; a control host 30, which is electrically connected to the first pneumatic part 12 and the second pneumatic part 22, and the control host 30 controls the first pneumatic part 12 and the second pneumatic part 22 to move synchronously, so that the damper 11 and the vehicle blocking device 21 are opened or closed synchronously.

[0035] In this solution, the existing compressed air power source is used as the driving power source of the car blocking device, which can replace the existing complex car blocking device, thereby simplifying the structure, reducing the cost, and facilitating the modification of the existing wind shield door 11. In addition, the control host 30 controls the first pneumatic part 12 and the second pneumatic part 22 to move synchronously, so that the wind shield door 11 and the car blocking device 21 are opened or closed synchronously, which can simplify the operation steps.

[0036] Specifically, the first pneumatic part 12 is a cylinder, the vehicle blocking device 21 is a vehicle blocking rod, and the first pneumatic part 12 drives the vehicle blocking rod to move linearly or rotate, so that the vehicle blocking rod blocks or avoids the vehicle.

[0037] The above arrangement has a simple structure and low cost.

[0038] In this solution, the coal mine underground wind gate vehicle blocking joint control device also includes a light sensor 61, which is arranged on the side of the vehicle blocking device 21 away from the wind gate 11, and the light sensor 61 is electrically connected to the control host 30, and the light sensor 61 is used to detect whether there is a vehicle passing by.

[0039] When the light sensor 61 detects a vehicle passing by, the control host 30 controls the first pneumatic part 12 and the second pneumatic part 22 to operate according to the detection result to open the windshield door 11 and the vehicle blocking device 21. In this way, the windshield door 11 and the vehicle blocking device 21 can be opened automatically without the need for personnel to get off the vehicle to operate.

[0040] like Figure 1 As shown, the coal mine underground air door vehicle blocking joint control device further includes a spray device 41, which is arranged on a side of the vehicle blocking device 21 away from the air door 11, and the spray device 41 sprays the bottom of the passing vehicle. It takes a certain amount of time for the air door 11 to be completely opened from closed. Through this arrangement, the waiting time of the vehicle can be fully utilized to clean the bottom of the vehicle, mainly the wheel position.

[0041] Since this device uses a light sensor, the driver does not have to open and close the windshield door next time, and the system needs to wait for more than 20 seconds to receive the signal. In order to make full use of the time while waiting for the windshield door to open, and to improve the air quality of the underground tunnel, this solution transforms the control host and the spray device linkage control system, and draws a signal source from the control host to realize that the windshield opening signal is the spray opening signal, and sprays the wheel hub and tire of the vehicle waiting in front of the vehicle blocking device. After 30 seconds (the time is adjustable), the spray automatically stops. Thereby, the device can achieve a greater effect and the driver's enthusiasm for use.

[0042] Furthermore, the coal mine underground air door and vehicle joint control device further comprises a control valve 42, the control valve 42 controls the opening and closing of the spray device 41, and the control valve 42 is electrically connected to the control host 30. In this way, the automatic opening and closing of the spray device 41 can be realized. The spray device 41 can be set to automatically stop after spraying for a period of time.

[0043] like Figure 1As shown, the coal mine underground air door and vehicle joint control device further includes a compressed air pipe group 51, and the first pneumatic part 12 and the second pneumatic part 22 are connected to the compressed air power source through the compressed air pipe group 51. The compressed air pipe group 51 is used to transport compressed air to provide power for the first pneumatic part 12 and the second pneumatic part 22.

[0044] Furthermore, the coal mine underground air door and vehicle joint control device further comprises a reversing valve 52 and a pressure regulating valve 53 arranged on the pressure air pipe group 51. The reversing valve 52 and the pressure regulating valve 53 are used to perform telescopic switching and pressure regulation on the first pneumatic part 12 and the second pneumatic part 22.

[0045] like Figure 1 As shown, the number of the air shield door 11, the number of the first pneumatic part 12, the number of the vehicle blocking device 21 and the number of the second pneumatic part 22 are all two.

[0046] Furthermore, the coal mine underground wind door and vehicle joint control device also includes a voice announcer 62, which is electrically connected to the control host 30 and is used to announce when the wind door 11 is opened or closed. The announcement can remind nearby personnel that the wind door 11 is opened or closed.

[0047] Furthermore, the coal mine underground air door vehicle blocking joint control device further includes an anti-pinch sensor 63, which is installed in a set range close to the air door 11, and the anti-pinch sensor 63 is electrically connected to the control host 30. When the anti-pinch sensor 63 detects a vehicle or a person, the control host 30 prevents the air door 11 from closing. In this way, the air door 11 can be prevented from clamping a vehicle or a person when closing, thereby improving safety.

[0048] In this solution, the existing compressed air power source is used as the driving power source of the car blocking device, which can replace the existing complex car blocking device, thereby simplifying the structure, reducing the cost, and facilitating the modification of the existing wind shield door 11. In addition, the control host 30 controls the first pneumatic part 12 and the second pneumatic part 22 to move synchronously, so that the wind shield door 11 and the car blocking device 21 are opened or closed synchronously, which can simplify the operation steps.

[0049] The main problem solved by this solution is to prevent passing vehicles from colliding with the windshield, and to equip the automatic car-blocking device in advance. The characteristics of this solution are: first, a car-blocking device and system are set in advance in front of the windshield to prevent vehicles from directly colliding with the windshield; second, the car-blocking device and system are linked with the windshield, and its opening and closing are automatically synchronized with the opening and closing of the windshield; third, the device has a simple structure, is stable and reliable, has a low failure rate, and is suitable for various harsh requirements in underground gas and coal dust, explosion-proof, humid and other environments; fourth, the car-blocking device has a simple structure and is easy to implement to avoid damage to the vehicle or cause a vehicle accident.
