First solenoid valve 402, second solenoid valve 403 and third solenoid valve 404 are three position four-way electromagnetic valve, the course of work
By taking column oil cylinder 105 as an example:
When first solenoid valve 402 is centrally located, 105 oil circuit of column oil cylinder be it is closed, oil cylinder keeps in situ at this time
It is motionless；
When needing column 1 to increase, first start Oil pump electrical machinery group 407, the electrification of the first side solenoid valve A, solenoid valve is cut at this time
Leftward position is shifted to, 105 rear end oil pocket of column oil cylinder is connected to fuel pump outlet, rod end oil pocket is connected to fuel tank 408.It is hydraulic
Oil is ejected oil cylinder piston by rear end oil pocket, and column 1 is driven to rise, and overall length is elongated, since column is fixed to grinding machine cylinder
In vivo.When needing to dismantle column, also need first to start 407, No. 1 side the solenoid valve B electrification of Oil pump electrical machinery group, at this time solenoid valve
Right positions are switched to, 1 oil cylinder rod end oil pocket of column is connected to fuel pump outlet, rear end oil pocket is connected to fuel tank.Hydraulic oil
Oil cylinder piston is retracted by rod end oil pocket, column 1 is driven to decline, overall length shortens, can thus be laid flat column 1 and dismantle
Transport grinding machine.
It lifts by crane oil cylinder 202 and telescopic oil cylinder 304 to control by second solenoid valve 402 and third solenoid valve 404 respectively, move
It is similar with column oil cylinder to make principle and process, is no longer described in detail.
A kind of application method of middle-size and small-size lining board of grinder more changing device: include the following steps:
1) column 1 is installed, after being installed, column oil cylinder 105 is accessed to the first electromagnetism of hydraulic power station by oil circuit
Valve 402 starts the first solenoid valve 402, keeps spool mobile to the end A, column oil cylinder 105 extends column 1 at this time, so that column 1
Pedestal 106 be close to grinding machine bottoms material and steel ball mixture, top plate 101 is close to lining board of grinder recess, is closed after adjustment
The first solenoid valve 402 is closed, keeps certain pressure that column 1 is secured firmly to inside grinding machine by column oil cylinder 105；
2) wirerope 201 of suspension cable 2 is hung on column lifting lug 102, while 201 lower end of wirerope connection lifting oil cylinder
202, oil cylinder 202 will be lifted by crane and pass through the second solenoid valve 403 of oil circuit access hydraulic power station；
3) after column 1 and suspension cable 2 install, the first segment telescopic arm 306 of swing arm 3 is fixed on by pin first
On the runing rest 104 of column 1, runing rest 104 can surround column 360 degree rotation, then by first segment telescopic arm 306 with
