Mobile stacker is a new type of high-efficiency continuous loading and unloading machinery, which is mainly used for loading and unloading iron ore (sand), coal, sand, etc. The machine is widely used at home and abroad because of its high operating efficiency.
In order for the mobile stacker to work normally, it is required to establish a strict shift handover and regular inspection system for operators at the work site. The operation and maintenance personnel are required to conduct frequent inspections on the site, and they can find and deal with the failure in time. The machine is equipped with a variety of alarm and protection devices. When some parts fail, it will be sent to the central control room and the site through the electronic control system The sound and light alarm signal reminds the operator to find out the cause, repair it in time, and eliminate the fault.
During the operation of the mobile stacker, the lubrication of the scraper conveyor chain should be inspected mainly, and the oil dripping point should be aligned with the gap between the inner and outer chain plates; the speed reducer should not have abnormal noise and the temperature rise should not be greater than 40 °C during the operation of the device. ; The wear of the wear-resistant plate fixed on the surface of the scraper body in the scraper device should be replaced in time when the wear degree reaches two-thirds of the body.
Check whether the bolting of the intermediate guide wheel in the scraper device of the mobile stacker is loose, if it is loose, it should be tightened in time; if the guide groove liner is worn, when the wear endangers the guide groove body, the liner should be replaced in time ; Check whether there is any deflection during the operation of the scraper. If it is deflected, adjust the screw and nut in the tensioning device at the tail of the sprocket to make the pretension of the two chains supporting the scraper consistent.
The wear of the wire rope hanging the rake of the mobile stacker should be observed and replaced in time when the wear is serious; whether the rake runs along the support track and the direction is stable, and whether there is any abnormal sound; whether the wear of the rake roller and track is critical Normal working conditions; whether the running mechanism of the end beam is stable, whether the shunting and reversing are reliable, and the meshing of open gears.
