Embodiment
As shown in Figure 1, the present embodiment provides a kind of hydraulic crawler excavator to turn round automatic safe caution system, it includes hydraulic oil
Case 1, main pump 2, main control valve 31, shuttle valve 32, main overflow valve 33, engine 4, rotary motor 5, electronic control unit 6, relay 7,
Acousto-optic warning lamp 8 and the grade component of pressure sensor 9.Wherein, main pump 2 is used to provide hydraulic power source for system, and rotary motor 5 is used to control
Excavator base machine revolution processed, main control valve 31 are used for the steering for switching rotary motor 5.2 power connector engine 4 of main pump, by starting
Machine 4 drives the operating of main pump 2 to produce hydraulic power source.The oil inlet of main pump 2 connects hydraulic oil container 1, the oil outlet of main pump 2 through fluid pressure line
Rotary motor 5 is connected through fluid pressure line, main control valve 31 is set on the fluid pressure line between main pump 2 and rotary motor 5.Main control valve 31
It is provided with left pilot pressure control mouth Pa and right pilot pressure control mouth Pb, left pilot pressure control mouth Pa, right pilot pressure control
Donsole Pb connects guide's hydraulic power source through fluid pressure line.Main overflow valve is connected with fluid pressure line between main pump 2 and main control valve 31
33.Driver's normal operating pilot handle, makes guide's hydraulic power source enter to left pilot pressure control mouth Pa or right pilot pressures
Control mouth Pb, the left revolution of control fuselage or right-hand rotation, and enter main control valve 31 without guide's hydraulic power source, control fuselage stops back
Turn.Shuttle valve 32 is provided with the first shuttle valve entrance, the second shuttle valve entrance and shuttle valve outlet, left pilot pressure control mouth Pa, right guide
