Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of working face automatic leveling device, it includes hydraulic power unit, the hydraulic power dress
The first hydraulic branch 17 and the second hydraulic branch 18, first hydraulic branch 17 are parallel on the main hydraulic oil efferent duct 16 set
On be sequentially installed with the first control valve 7, the first check valve 5 and first hydraulic cylinder 2；It is installed successively on second hydraulic branch 18
There are the second control valve 12, the second check valve 11 and second hydraulic cylinder 10；The piston of the first hydraulic cylinder 2 and second hydraulic cylinder 10
Workbench 1 is installed, the pedestal of first hydraulic cylinder 2 and second hydraulic cylinder 10 is fixed in the first equipment plane 14 at the top of bar；
First control valve, 7 and second control valve 12 is mounted in the second equipment plane 15, passes through pin in the second equipment plane 15
Axis 9 is hinged with counterweight component 8, and the top of the counterweight component 8 is provided with 801 and second contact 802 of symmetrical first contact；Institute
The first contact 801 and the cooperation of the first control valve 7 are stated, and controls the opening and closing of the first control valve 7；Second contact 802
Coordinate with the second control valve 12, and controls the opening and closing of the second control valve 11.
Further, the hydraulic power unit includes fuel tank 6, and the fuel tank 6 passes through fluid pressure line and 13 phase of hydraulic pump
Even.
Further, the counterweight component 8 is in vertical direction always under the effect of gravity, can be flat with the second equipment
The swing in face 15 and swing.
Further, unidirectional with second on the first hydraulic branch 17 between first check valve 5 and first hydraulic cylinder 2
It is connected respectively with two position three-way valve 4 by oil pipe on the second hydraulic branch 18 between valve 11 and second hydraulic cylinder 10, described two
Position three-way valve 4 is connected by third check valve 3 with fuel tank 6.
The control method of working face automatic leveling device described in any one：
As Fig. 1 provides pressure oil, counterweight component 8 is in perpendicular when crane is in operation on level ground by hydraulic pump 13
