Safety control device for dumping tank body of mixed iron car

Abstract

The invention relates to a tank body tilting safety control device of an iron mixing vehicle, which belongs to blast furnace iron making and relates to a blast furnace molten iron transport device. The tank body tilting safety control device comprises a vehicle body, a tank body, a tilting mechanism, a high speed receptacle and a junction box, wherein the tank body, the tilting mechanism, the high speed receptacle and the junction box are arranged on the vehicle body, the tilting mechanism is connected with a large gear of the tank body through a chain, and an electrical control box is arranged on the ground and electrically connected with the high speed receptacle. The tank body tilting safety control device is characterized in that a tilting two-way contact is arranged on the center line of the tank body, a zero position contact is arranged under the center line, the tilting two-way contact and the zero position contact respectively correspond to a tilting travel switch and a zero position travel switch which are arranged on a platform, and the tilting travel switch and the zero position travel switch are electrically connected with the junction box. The tank body tilting safety control device has the advantages of novel concept, simple structure, easiness in operation and low manufacturing cost. The position of the tilting travel switch can be adjusted so as to adapt to different tilting angles of the tank body, the tilting process is safe and reliable, an accident that molten iron falls on the ground because the tank body is tilted and out of control due to mechanical, electrical and operational causes is effectively avoided, waste of the molten iron is reduced, the cost for maintenance and spare parts is reduced, the online operation turnover rate of the iron mixing vehicle is increased, and smooth production is guaranteed.

Description

technical field [0001] The invention belongs to blast furnace ironmaking, in particular to a blast furnace molten iron transportation device. Background technique [0002] The mixed iron car is a special equipment for transporting the molten iron from the blast furnace to the steelmaking plant. The cylindrical molten iron tank is installed on the car body, and a tilting mechanism with a transmission motor is installed on the platform of the car body. The output sprocket of the tilting mechanism is connected with the large ring gear of the tank body through a chain to drive the tank body to rotate and tilt. Pour out the molten iron, and then rotate and reset after pouring out the molten iron. The current tipping mechanism is controlled by a cam controller, one end of the chain is connected with the small sprocket, and the other end is connected with the end gear of the cam controller, and the circuit elements for controlling the tilting angle of the tank are connected to dif...

AI Technical Summary

Problems solved by technology

The defects are: the device is often caused by: 1. Improper adjustment of the brake clearance of the transmission motor, and the brake cannot be opened; 2. There is a lot of slagging in the tank, causing the large ring gear to climb teeth; 3. The contacts of the cam controller are in poor contact; 4. Due to the accumulation of errors in the chain transmission and manual misoperation, the tank body is overturned out of control, a large amount of molten iron falls to the ground and solidifies, and the vehicles and railways are damaged, causing major economic losses and endangering the personal life of the operators. Safety, low turnover rate for online operation of mixed-rail vehicles
