Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment, in particular to an automatic contact power supply device for a molten iron tank car. Background Art

[0002] The molten iron ladle is a special vehicle used by metallurgical enterprises to transport molten iron to the iron casting machine for casting iron blocks or to the steelmaking workshop to inject the molten iron into the mixing furnace for storage, or directly inject the molten iron into the steelmaking furnace for steelmaking. At present, in some old steel mills, the distance between the steelmaking workshop and the blast furnace is relatively far, and the operation time of the molten iron ladle from the maintenance workshop - the iron outlet - the desulfurization workshop - the steelmaking workshop - the maintenance workshop is about 8 hours. Therefore, the molten iron ladle must be covered to reduce the heat loss of the molten iron ladle during transportation, especially to reduce the heat loss in rainy and snowy weather, so as to achieve the purpose of keeping the molten iron ladle and the molten iron warm. However, setting the molten iron ladle cover requires the equipment on the molten iron ladle to be powered and driven.

[0003] However, there is currently no automatic power supply device for molten iron tank cars. To connect to the power supply, the tank cars need to run to the designated wiring pile position, and then manually operate the plug and socket to connect, which poses certain safety hazards and delays, and also increases the labor intensity of employees. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] The purpose of the present invention is to solve the problem that in the prior art, the molten iron tank car has no automatic power supply device, and the tank car needs to run to the designated wiring post position and then manually operate the plug and socket to connect to the power supply, and an automatic contact power supply device for the molten iron tank car is proposed.

[0006] 2. Technical solution

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The molten iron tank car automatic contact power supply device comprises a tank car, a sleeper and a rail, wherein the rail is fixedly connected to the top of the sleeper, the tank car is rotatably connected to the top of the rail, and one end of the sleeper is fixedly connected to a base;

[0009] The top of the base is connected with a mounting block through a turnbuckle screw, the top of the mounting block is fixedly connected with a support rod, a fixing seat is slidably sleeved on the support rod, one side of the fixing seat is fixedly connected with a conductive slot, and a nut is threadedly sleeved on the top of the support rod;

[0010] A spring is sleeved on the support rod, and both ends of the spring are fixedly connected to a fixing seat and a nut respectively. One side of the tank car is fixedly connected to a plurality of conductive fixing plates corresponding to the positions of the conductive slots;

[0011] A conducting wire is fixedly connected to one end of the conductive fixing plate away from the tank car, and laser locators correspondingly arranged at positions are fixedly connected to the tank car and the rail.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In the present invention, manual operation can be eliminated. When the molten iron tank car arrives at a specific track range for loading and unloading molten iron, the conductive rod device installed on the tank frame will contact the conductive groove fixed on the sleeper power supply device to connect the power supply.

[0022] (2) In the present invention, the positions where the molten iron tank car needs to be covered and uncovered are mainly at the slag skimming pool of the cast iron machine, the molten iron spout of the blast furnace and the molten iron chute in the cast pipe area. When the molten iron tank car runs to the specified range of the slag skimming pool, the molten iron spout of the blast furnace and the molten iron chute of the cast pipe area, the locomotive driver determines whether the tank car has stopped at the specified position based on the information fed back by the laser locator. When the tank car has stopped at the specified position, the three conductive rods installed beside the molten iron tank rack will contact the three conductive grooves of the sleepers fixed at the corresponding positions, thereby connecting to the power supply, thereby providing power to the covering hydraulic station on the molten iron tank car.
