Description

Accident Roll Choke Removal Device

The present invention relates to a device for removing choke from a roll during choke removal, and the following operation is smoothly performed by easily separating and removing a state in which separation and removal is impossible by the conventional method due to various problems of chokes. It is about the removal device of the accidental roll choke that makes it possible.

The removal method of the accidental roll choke in the prior art is shown in Figs. 1 (a) to 1 (c). In general, the choke 52 is assembled to the roll 53 during rolling in a Young Yeon factory. It serves to rotate and receives the heavy load in the limited space of the rolling mill in the form of a square box in which the bearing is assembled therein is a facility to help and support the rotation of the roll (53). Therefore, as the use time elapses, the dimensional shape of the choke 52 is easily worn and deformed, and it causes various failures due to scale or cooling water penetration into the choke 52 during use. (52) When grease is injected into the inside and is replaced after rolling for a predetermined time, and the choke 52 is not disassembled from the roll 53 when the choke 52 is removed and assembled, the first (a) to the first (c) degrees are shown. The choke 52 is separated through the various methods shown in FIG.

When removing and removing the accident choke 52 as shown in Figs. 1 (a) to 1 (c), the work load is always increased due to safety risks or prolonged work delays, and equipment and parts are damaged. Many problems arise, and specifically, these various types of accident roll 53 choke 52 strongly collide with other heavy materials to force separation of the choke 52 from the roll 53 by the impact generated at that time. You are using an unusual way of working.

According to the prior art work method, heavy weights collide with each other, and thus there is a possibility of large facility accidents, shortened parts life and failure, and high risk of safety accidents. Various problems have arisen, such as a delay in time, which causes a decrease in productivity.

The present invention has been made to solve this problem in the prior art, and the upper body is installed on the lower support to be movable by the shaft, and the choke for pulling and choking the distance between the choke and the choke Hooks are mounted on the left and right arm cylinders on both sides of the body, the cylinder is installed in the center of the body to adjust the width, the close contact is attached to facilitate the close contact with the end of the roll, and to remove the choke smoothly A central cylinder mounted at the center of the front of the body, a cylinder which is disposed on the lower stand at the center of the lower front of the body, cylinders for moving the body, and nipples connected to the hoses at the left and right sides are installed and operating levers for operating each cylinder. The operation panel disposed at the rear side, the moving wheel installed at the lower part to move the body, and the wheel And such as to so that the direction operation provided coupled to the lower body handle, operates through the power cable to constitute an accident the roll chock removal device comprising a hydraulic tank and the hydraulic motor is installed on the lower body so as to supply the hydraulic pressure to the control panel through a hydraulic hose.
