Description

Technical Field

[0001] This utility model relates to an anti-pulling device for the overturning plug of a torpedo ladle transport train, belonging to the technical field of molten iron transport equipment. Background Technology

[0002] Torpedo ladle transport trains are responsible for transporting molten iron from outside the steel plant. Each torpedo ladle train is equipped with a torpedo ladle tilting socket, which connects to the train's tilting motor, brake, and vertical limit switch. Correspondingly, at the torpedo ladle tilting station, there is a torpedo ladle tilting plug connected to the control system in the torpedo ladle control room. This plug is matched with the tilting socket on the torpedo ladle train. When tilting is needed, the tilting plug is inserted into the socket of the desired torpedo ladle, and the tilting operation can then be performed from the main control room of the tilting station. In actual operation, sometimes the torpedo ladle train starts moving before the tilting plug is disconnected, causing the cable of the tilting plug to be pulled off, making tilting impossible. In severe cases, this can damage the tilting electrical equipment and control system, requiring more than 3 hours to restore the tilting plug. This significantly impacts the production of the steel and ironworks, causing molten iron accumulation in the ironworks and insufficient molten iron in the steelworks. Summary of the Invention

[0003] The purpose of this utility model is to provide a torpedo ladle transport train tilting plug interlocking anti-pulling device. By installing a tilting plug connection detection proximity switch on the tilting socket and connecting it to the travel control circuit, when the tilting plug is plugged into the tilting socket, the tilting plug connection detection proximity switch sends an interlock signal, preventing the torpedo ladle train from moving and preventing accidents where the tilting plug is not removed before the train departs. Furthermore, by adding a connecting plug to the torpedo ladle, the preceding train cars can be driven away while the following torpedo ladle can continue to tilt without being affected by the interlock. This ensures normal iron transport and tilting while preventing accidents where the tilting plug cable is pulled out and the train cannot tilt, thus ensuring production safety and solving the aforementioned problems in the background art.

[0004] The technical solution of this utility model is: a tilting plug interlocking anti-pulling device for a torpedo canister transport train, comprising a connecting plug, a connecting socket, a tilting plug connection detection proximity switch, and a tilting plug connection detection relay. The travel control circuit and the tilting plug connection detection relay are installed on the torpedo canister locomotive, and the connecting plug and connecting socket are installed on each torpedo canister. Adjacent torpedo canisters are connected via the connecting plug and connecting socket circuit. The travel control circuit is connected in series with the connecting plug and connecting socket of each torpedo canister through the tilting plug connection detection relay. Each torpedo canister is provided with a tilting socket, and a tilting plug is provided at the tilting position of the torpedo canister tilting station. The tilting plug and tilting socket are matched, and the tilting plug connection detection proximity switch is installed on the tilting socket. The tilting plug connection detection proximity switch is connected to the tilting plug connection detection relay through the connecting plug and connecting socket.

[0005] It also includes a tilt plug connection indicator, which is connected to a tilt plug connection detection relay.

[0006] The tilt plug connection indicator is a tilt plug connection indicator light.

[0007] The beneficial effects of this utility model are as follows: By setting a tilt plug connection detection proximity switch on the tilting socket and connecting it to the travel control circuit, when the tilt plug is plugged into the tilting socket, the tilt plug connection detection proximity switch sends an interlock signal, preventing the torpedo ladle train from moving and preventing accidents such as the train leaving before the tilt plug is unplugged; and by adding a connection plug to the torpedo ladle, the preceding train cars can be driven away while the following torpedo ladle continues to tilt without being affected by the interlock, thus ensuring normal iron transport and tilting while avoiding accidents such as the tilt plug cable being pulled off and the train being unable to tilt, thereby ensuring production safety.

Detailed Implementation

[0011] To make the purpose, technical solution, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described implementation cases are only a small part of this utility model, not all of them. All other implementation cases obtained by those skilled in the art based on the implementation cases of this utility model without creative effort are within the protection scope of this utility model.

[0012] A tilting plug interlocking anti-pulling device for a torpedo canister transport train includes a connecting plug, a connecting socket, a tilting plug connection detection proximity switch, and a tilting plug connection detection relay 8. The travel control circuit 12 and the tilting plug connection detection relay 8 are installed on the torpedo canister locomotive. The connecting plug and connecting socket are installed on each torpedo canister. Adjacent torpedo canisters are connected via the connecting plug and connecting socket circuit. The travel control circuit 12 is connected in series with the connecting plug and connecting socket of each torpedo canister through the tilting plug connection detection relay 8. Each torpedo canister is provided with a tilting socket, and a tilting plug is provided at the tilting position of the torpedo canister tilting station. The tilting plug and tilting socket are matched. The tilting plug connection detection proximity switch is installed on the tilting socket and is connected to the tilting plug connection detection relay through the connecting plug and connecting socket.

[0013] It also includes a tilt plug connection indicator 13, which is connected to a tilt plug connection detection relay 8.

[0014] The tilt plug connection indicator 13 is a tilt plug connection indicator light.

[0015] In practical applications, when the torpedo ladle train transports molten iron to the torpedo ladle tipping station, after reaching the tipping position, the tipping plug 18 is inserted into the tipping socket on the torpedo ladle in the tipping position. At this time, the tipping plug connection detection proximity switch on the tipping socket is activated, and the normally open contact of the tipping plug connection detection proximity switch closes. Through the connection socket of this section of the torpedo ladle and the connection plug of the previous section of the torpedo ladle, the signal is transmitted section by section to the tipping plug connection detection relay 8 on the torpedo ladle locomotive. The coil of the tipping plug connection detection relay 8 is energized, and the normally open contact 10 of the tipping plug connection detection relay closes. The tipping plug connection indicator light indicates the tipping plug connection. At the same time, the normally closed contact 11 of the tipping plug connection detection relay opens, cutting off the torpedo ladle train's travel control circuit 12, and the torpedo ladle train cannot move. Once the molten iron in the torpedo ladle has been tilted, the tilting plug is disconnected. The coil of the tilting plug connection detection relay 8 on the torpedo ladle locomotive is de-energized, the normally open contact 10 of the tilting plug connection detection relay opens, and the tilting plug connection indicator light goes out, indicating that the tilting plug connection is disconnected. The torpedo ladle train can then proceed. When only the tilted torpedo ladle needs to be left behind while the other torpedo ladle sections are moved, the connection plug of the remaining torpedo ladle section is disconnected. The coil of the tilting plug connection detection relay 8 on the torpedo ladle locomotive is de-energized, the normally open contact 10 of the tilting plug connection detection relay opens, and the tilting plug connection indicator light goes out. The torpedo ladle train can then proceed, while the remaining torpedo ladle at the tilting station can continue to be tilted. Example

[0016] Taking a torpedo car train with n torpedo carcasses as an example, its working process is as follows:

[0017] When the torpedo ladle train transports molten iron to the torpedo ladle tipping station, upon reaching the tipping position, the tipping plug 18 is inserted into the tipping socket 24 of the nth torpedo ladle, which is in the tipping position. At this time, the nth torpedo ladle tipping plug connection detection proximity switch 21 on the nth torpedo ladle tipping socket 24 detects that the tipping plug 18 is inserted in place. The normally open contact 20 of the nth torpedo ladle tipping plug connection detection proximity switch closes, the coil of the tipping plug connection detection relay 8 is energized, the normally open contact 10 of the tipping plug connection detection relay closes, the tipping plug connection indicator 13 provides connection indication, and at the same time, the normally closed contact 11 of the tipping plug connection detection relay opens, cutting off the travel control circuit 12, and the torpedo ladle train cannot move.

[0018] When the molten iron in the nth torpedo ladle is tilted, the tilting plug 18 is unplugged. The coil 8 of the tilting plug connection detection relay on the torpedo ladle locomotive is de-energized, the normally open contact 10 of the tilting plug connection detection relay is opened, and the tilting plug connection indicator light does not light up, indicating that the tilting plug 18 connection has been disconnected, and the torpedo ladle train can be started.

[0019] When only the nth torpedo canister needs to be left for tipping while the other torpedo canisters are driven away, disconnect the connector 25 of the (n-1)th torpedo canister. The tipping connector detection relay coil 8 on the torpedo canister locomotive will be de-energized, the normally open contact 10 of the tipping connector detection relay will open, the tipping connector indicator light will not illuminate, the torpedo canister train can start moving, and the torpedo canisters left at the tipping station can continue to tip.
