[0002] The pre-repair warehouse is a special repair workshop for the maintenance of railway freight cars. It is used to repair railway freight cars. According to the different objects to be repaired, they can be divided into boxcars, tank cars, coal trucks, etc. Different types of vehicles have different heights.

[0003] The basic process of vehicle shunting in and out of the warehouse is:

[0004] The dismantled vehicle is towed to the pre-repair warehouse by a road-rail tractor. During the traction process, it is necessary to pass through the warehouse door. After the vehicle is in place, the intelligent iron shoe is used to lock the position of the vehicle. Then the road-rail tractor withdraws and the warehouse door is closed after the withdrawal. After the warehouse door is closed, the vehicle can be inspected. After the inspection is completed, the road-rail tractor is used to tow the repaired vehicle out of the warehouse. In this process, the warehouse door needs to be opened and closed repeatedly. During the opening and closing process, it has the characteristics of frequent operations, complex links, prominent safety issues and all-weather operation. For example, there is a problem of vehicle collision and collision with the warehouse door due to insufficient opening height of the warehouse door, which needs to be solved urgently.

[0021] In the picture: 01 vehicle, 02 track, 03 intelligent iron shoe, 04 garage door, 05 electric control cabinet, 06 traffic light, 07 voice player, 08 intelligent camera, 09 travel switch, 10 laser, 11 warning line. DETAILED DESCRIPTION

[0022] This embodiment introduces an anti-collision interlock alarm device for vehicles in a pre-repair depot shunting operation, which is used to ensure the safety of shunting work.

[0023] During the shunting process, vehicle 01 is towed from outside the depot to the inside of the depot and then parked on track 02. In order to ensure that the vehicle to be inspected does not slip when parked on the track, the staff will install smart iron shoes on the track to limit the movement of the vehicle. At the same time, when the vehicle on the track is shunted away, the staff also needs to remove the smart iron shoes 03. In this embodiment, smart iron shoes 03 refer to adding an induction switch to the smart iron shoes, through which it can sense whether the smart iron shoes are removed. The induction switch is preferably a pressure-triggered switch. When the smart iron shoes are subjected to the pressure of the wheel hub, the switch will be triggered to close, forming an electrical signal. A signal transmission module is set in the smart iron shoe 03. When the smart iron shoe is removed, an electrical signal is sent out, and the depot door is automatically opened by remote control of the electric control cabinet.

[0024] The above-mentioned vehicles are railway freight vehicles, including but not limited to boxcars, tank trucks, and coal trucks.

[0025] refer to Figure 1 to Figure 2 In this embodiment, a signal is synchronously sent to the cab of the traction vehicle through the smart iron shoe, and the signal will be displayed on the control screen of the traction locomotive, indicating that the smart iron shoe has been removed and shunting can be carried out, which solves the potential safety hazards in the process of removing the smart iron shoe during the shunting operation.

[0026] In a traditional scenario, the warehouse door 04 is opened by an operator using a mechanical button, that is, the warehouse door opens by pressing a button.

[0027] In this embodiment, the automatic opening of the warehouse door 04 is realized by the linkage of the intelligent iron shoe and the warehouse door. The warehouse door is a gate or a rolling door that opens up and down, that is, it is opened up and down.

[0028] To improve the control system of the warehouse door, specifically, the electric control cabinet 05 adopts PLC programming control, and can also adopt a single-chip microcomputer and be equipped with a radio receiving and transmitting module.

[0029] A traffic light 06 and a voice player 07 are installed on one side of the track where the warehouse door 04 is located. The traffic light and the voice player are electrically connected to the electric control cabinet 05 and communicate with the electric control cabinet to remind surrounding staff through optical and sound methods: the warehouse door has been opened, please be careful to avoid it!

[0030] A smart camera 08 is installed on the wall of the warehouse door, which is connected to the electric control cabinet by electrical connection and communicates with the electric control cabinet. When the smart camera detects that there are no workers in the monitoring area around the vehicle, the red light turns green. When the tractor driver sees the red light turn green, he can carry out the tractor operation.

[0031] A travel switch 09 is installed at the top and bottom of the warehouse door respectively. The travel switch is connected to the electric control cabinet by electrical connection and communicates with the electric control cabinet. When the warehouse door is in place, it stops automatically to prevent losses caused by the warehouse door not being lifted or lowered into place.

[0032] The laser 10 is installed on both sides of the warehouse door, one on each side. When the warehouse door is lifted into place, it illuminates the safety boundaries on both sides of the vehicle, forming two warning lines 11 on the platforms on both sides of the track. The laser 10 is electrically connected to the electric control cabinet, and is connected to the electric control cabinet by electrical connection, and communicates with the electric control cabinet.

[0033] The basic process of vehicle departure is as follows: after the inspection is completed, the staff removes the smart iron shoe 03. After the removal, the smart iron shoe sends an electrical signal to the computer electric control cabinet, and receives a signal that the smart iron shoe has been removed. The electric control cabinet controls the smart camera through the electrical signal. When the smart camera detects that there are no staff in the monitoring area around the vehicle, the red light turns green, and the laser is powered and turned on to form a laser boundary (two warning lines 11) within 2 meters on both sides of the vehicle. Synchronously, the voice announcer plays a high-power voice announcement, and the tractor driver observes and tows the vehicle to depart from the warehouse, and the departure is completed.

[0034] The basic process of vehicle exiting the warehouse is as follows: the tractor pulls the vehicle to be inspected and repaired from the outside. When the vehicle is in place along the track, the smart iron shoes are placed on the wheels of the vehicle to prevent slipping. The smart iron shoes send out an electrical signal, the computer electrical control cabinet controls the warehouse door to close, and the green light turns red. At the same time, the laser is turned off, and the voice announcer stops broadcasting. After the tractor is evacuated, the corresponding maintenance work can be carried out.

[0035] Through the implementation of the above-mentioned technical means, workers can fully avoid vehicles, thereby solving related safety hazards, avoiding collisions between vehicles and personnel and warehouse doors, etc., and providing technical guarantees for safe production.

[0036] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in the field should fall within the scope of protection determined by the claims of the present invention.
