Scraper Winch Operation

Most of the scraper winches are used in the smelting workshop of the aluminum plant, which is used to clean the key mechanical equipment of the impurities on the surface of the aluminum liquid in the mixing tank, and work under high temperature environment; Install the slag holding mechanism. The general electric rake process is an important process before the continuous casting of the aluminum ingot. The purpose is to electrolyze the residual alumina residue in the aluminum, and then perform continuous casting to ensure the purity of the shaped aluminum ingot.

In mining applications, the scraper winch is an indispensable machine. It can be said that it plays a very important role in the development of mining. It mainly has these structural devices, including deceleration device, main reel, auxiliary reel, control device, steel wire guide device and electric motor. These components are installed separately. Inside and outside the housing. In addition, when the motor of the scraper winch is started, when the internal gears are not braked, the internal gears rotate, and the reel does not move under the action of the steel rope and the rake bucket; The gear is braked by the operating device, then its corresponding reel will rotate the rope, and at the same time it will drive the rake bucket to move. At this time, the other gear is not braked, and its reel is driven by the steel rope to rotate Release the steel rope. By operating the brakes so as to brake the internal gears of the main and auxiliary drums alternately, the rake bucket reciprocates to carry out the raking work.

①When the scraper winch is raking the mine underground, it generally adopts temporary fixing method and asexual fixing foundation; its fixing is firm, and it is often checked whether the fixed pile of the machine may be loosened, and problems should be dealt with in time to ensure the operation of the equipment.

② often conduct detailed inspections on all parts of the electric harrow. Such as the lubrication of various parts, whether there is a lack of oil or oil leakage; the wear of the rake bucket, bucket teeth, pulleys, rollers, transmission gears and gear shafts; the fixing of the steel wire rope and the broken wires; whether the brake bands are excessively worn or Whether there is slipping phenomenon; often check and adjust the brake gap of the brake belt to ensure that the brake is flexible and reliable, prevent the brake belt from overheating and excessive wear, and keep the shield and sealing device intact to avoid falling into the mine rock.

3 Pay attention to the extreme conditions of the rake bucket at any time. Prevent excessive accumulation of ore rocks in front of the rake bucket or excessive block size, so as to avoid equipment accident caused by excessive resistance of the group.

④ Always pay attention to the operation sound of the winch to distinguish whether the equipment is running and the load is normal. When the temperature of the machine exceeds 70 ° C, it should be stopped and put into operation after the temperature drops.
