Rolling mill pressure head auxiliary dismounting and mounting device and pressure head dismounting method

Abstract

The invention provides a rolling mill pressure head auxiliary dismounting and mounting device and a pressure head dismounting method. The rolling mill pressure head auxiliary dismounting and mountingdevice comprises a rail flat car, a lifting operation platform, a main controller and a remote controller; the lifting operation platform is detachably arranged on the rail flat car; the main controller is arranged on the rail flat car; a traveling drive mechanism of the rail flat car and a lifting drive mechanism of the lifting operation platform are connected with the main controller; the remotecontroller is in wireless connection with the main controller; and when the remote controller sends an action instruction to the main controller, the traveling drive mechanism and the lifting drive mechanism are controlled by the main controller to operate or stop. The rolling mill pressure head auxiliary dismounting and mounting device and the pressure head dismounting method can make a single worker enter a rolling mill and rapidly dismount or mount a pressure head of a pressing device inside the rolling mill, the dismounting, mounting and maintaining efficiency of the pressure head is improved, and safety of dismounting and mounting of the pressure head is improved.

Description

technical field [0001] The invention relates to rolling mill overhaul technology, in particular to an auxiliary dismounting device for a rolling mill pressure head and a method for disassembling the pressure head. Background technique [0002] The roughing mill is one of the main equipments of the hot-rolled sheet and strip production line, and the rolling mill pressing device is the key equipment for rolling the slab in the roughing mill. When the pressing device of the rolling mill breaks down, the rolling line must be shut down and the pressure head of the pressing device must be removed for inspection and replacement. Put the pressure head on the support roller, remove the flange bolts of the pressure head and the oil return pipe, then lift up the screw rod, pull out the support roller, and finally lift the pressure head to the ground for inspection and assembly by a crane. After the pressure head is assembled Lifted to the backup rolls and pushed into the rolling mill ...

AI Technical Summary

Problems solved by technology

[0003] Disadvantages of the above method: 1) The removal of the indenter is realized through the action of the on-site equipment. After each equipment action, the on-site equipment needs to be re-listed for power failure, and there are potential safety hazards of mechanical damage for multiple actions; 2) Pumping the support roller When the on-site hydraulic equipment cannot stop

Due to non-stop maintenance of hydraulic equipment, many safety accidents have occurred, so now the owner must first shut down the entire line of hydraulic equipment and list the hydraulic equipment. After the maintenance of the entire line is completed, the hydraulic pressure can be sent before the maintenance of the pressing device is performed. The maintenance efficiency is not high.
