Coil conveying vehicle with automatic opening and closing heat preservation mechanism

Abstract

The invention discloses a coil conveying vehicle with an automatic opening and closing heat preservation mechanism. The coil conveying vehicle comprises a rail which is laid between a coil unloading position and a slow cooling area of a steel coil warehouse and a coil conveying vehicle body capable of moving a steel coil on the coil unloading position from the position to the slow cooling area ofthe steel coil warehouse; the coil conveying vehicle body is arranged on the rail and comprises a vehicle body frame; the positions, at the four corners, of the lower end of the vehicle body frame areprovided with wheel groups capable of driving the vehicle body frame to move respectively; the wheel groups are arranged on the vehicle body frame through supporting mechanisms respectively and can move along the rail; the middle part of the lower end of the vehicle body frame is provided with a wheel drive device capable of driving the wheel groups to rotate; and the middle part of the upper endof the vehicle body frame is provided with a saddle used for placing the steel coil. The coil conveying vehicle is high in automation degree, can automatically drive a heat preservation cover to be opened or closed by utilizing a heat preservation cover opening and closing drive device so as to enable the treated steel coil to obtain the expected effect as well as is reliable in running and smallin maintenance quantity.

Description

technical field [0001] The invention relates to the technical field of steel production, in particular to a rolling car with an automatic opening and closing heat preservation mechanism. Background technique [0002] The raw materials required for cold-rolling plain carbon steel, high-strength steel, and ultra-high-strength steel are all from hot rolling, and the transportation is mainly through automobiles or online transportation systems from hot rolling to cold rolling raw material storage. [0003] The coil transportation of the hot rolling line after the coiler only refers to the transportation of steel coils. If the steel coils need heat preservation, slow cooling, annealing, etc., special heat preservation pits, heat preservation furnaces or bell furnaces and follow-up heat treatment must be set up. technology can be realized. Not only does it take up space, but it also requires a large investment and high energy consumption, which virtually increases the transportat...

AI Technical Summary

Problems solved by technology

[0005] 1) The most prominent problem existing in the thermal insulation device of the rolling line is that the interval time between strip steel coiling and entering the thermal insulation device is too long. The metallographic structure of the strip steel has been changed or completed. The off-line slow cooling method can not meet the quality requirements of high-strength steel. still not ideal

[0006] 2) This type of heat preservation device is placed statically on the coiling platform, which belongs to the offline heat preservation mode, which increases the difficulty of scheduling the driving, greatly improves the operation rate of the driving, and restricts the production capacity of the production line. Small-scale processing is possible, and mass production is possible. still unable to organize effectively

[0007] 3) Regardless of the addition of heat preservation pits, heat preservation furnaces, bell furnaces, heat treatment and other heat preservation devices, the cost is generally high, and the renovation period is long, which affects the normal production of the production line

[0009] 1) Lifting equipment must be installed on the exit side of the coiler to lift or cover the insulation cover. Since there is no rotation or lateral movement function, when the steel coil needs to be lifted, the insulation cover must be removed by manual chain hoists. Affect the driving time for hoisting steel coils

[0010] 2) In the slow cooling area of ​​the steel coil warehouse, hoisting equipment integrating lifting, lateral movement and lowering functions must be installed. Due to the long length of this equipment, it must occupy the space in the steel coil warehouse. In order not to affect the storage capacity of the warehouse area, the process layout It often protrudes out of the factory building, but it affects the overall visual effect of the factory area; if it is placed in the factory building, it will cause a significant decrease in the total amount of steel coils stacked in the steel coil warehouse, which is obviously not suitable

[0011] 3) Since this kind of lifting equipment requires accurate positioning of the parking space, the whole lifting process can be completed by lowering, moving forward, hooking, lifting, retreating, driving and lifting, etc., which takes a long time. Over time, there is accumulation error, the situation where the alignment effect gradually deteriorates
