Finished sheet strip roll feeding and unloading device and work method thereof

Abstract

The invention relates to a finished sheet strip roll feeding and unloading device and a work method thereof. A reel of a coiling machine is horizontally and horizontally arranged, the reel is sleevedwith a finished roll, and horizontally and transversely arranged conveying rails are mounted below the coiling machine. A walking trolley operates on the conveying rails in a guide and driving manner,and a vertically arranged lifting sliding plate is vertically arranged in the middle of the walking trolley. A saddle is fixedly mounted at the upper end of the lifting sliding plate, and a lifting hydraulic cylinder is mounted at the lower end of the lifting sliding plate. A pressure sensor is additionally mounted on an ascending oil outlet hole of the lifting hydraulic cylinder. Wheels are symmetrically mounted at the position, on the front side and the rear side of the walking trolley, of the two sides of the lifting sliding plate, and the wheels on the two sides are embedded into the horizontal rails in a limiting and rolling manner. Chain wheels are coaxially mounted on the outer sides of the wheels, and chains capable of being matched with wheel teeth of the chain wheels are fixedlylaid on the outer sides of the horizontal rails. According to the finished sheet strip roll feeding and unloading device and the work method thereof, the human operation problems are solved, operation is safe and stable, and automatic operation is achieved; and operation personnel are saved, the equipment shutdown time is shortened, and the maintenance cost and the production cost are reduced.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a coil loading and unloading device for finished strip coils and a working method thereof. Background technique [0002] At present, the coil unloading process of units such as rolling mill coiler, pickling coiler galvanizing and color coating production line is that when the coiler of the unit completes the production of finished coils, the operator operates the coil unloading trolley device to move to the transmission side The saddle of the unloading trolley rises under the lifting of the hydraulic cylinder to hold the finished coil. After the diameter of the coil shrinks, the coil is lifted by the saddle of the unloading trolley. Operate the saddle of the unloading trolley to rise and watch the coil on the coiler. Stop after there is a gap between the top of the reel and the core, and then move the saddle to the operation side to move the trolley to lift the reel away fr...

Problems solved by technology

[0002] At present, the coil unloading process of units such as rolling mill coiler, pickling coiler, galvanizing and color coating production line is that when the coiler of the unit completes the production of finished coils, the operator operates the coil unloading trolley device to move to the transmission side The saddle of the unloading trolley rises under the lifting of the hydraulic cylinder to hold the finished coil. After the diameter of the coil shrinks, the coil is lifted by the saddle of the unloading trolley. Operate the saddle of the unloading trolley to rise and watch the coil on the coiler. Stop after there is a gap between the top of the reel and the core, and then move the saddle to the operation side to move the trolley to lift the reel away from the reel of the coiler to complete the unloading process. The gap on the reel after shrinking is relatively small, and the core strip of the finished coil is generally not completely attached to the core wall, making it difficult to observe the gap. During the night shift, the inside of the core and the reel of the coiler is relatively dark and the light is dark, making it difficult to inspect. To the gap, every time the unit completes a finished roll, the operator needs to check the gap manually. Observation is difficult, which seriously wastes manpower and affects production efficiency. Often, the unloading saddle will be caused by failing to check the gap or not checking in place. When the finished roll is lifted too high, the reel of the coiler is over-forced, often and repeatedly, the shaft of the coiler is cracked or broken, and the main shaft of the coiler is damaged, and the unit stops. The production cycle of this shaft is long and the cost is very high. High, which seriously affects the production operation, increases the production cost, and the maintenance is troublesome and time-consuming. The failure rate is high, resulting in a low start-up rate of the equipment.
