Description
Technical field
The utility model belongs to rotary drilling rig technical field, in particular to a kind of rotary digging driller mast control device.
Background technique
Existing rotary digging driller mast control method are as follows: mast be electric control guide oil again by guide oil control high pressure oil
The mode of operation that moves back and forth of oil cylinder is carried out, specifically by the high pressure hydraulic oil of main pump output to pair valve, then guide's gear pump
Export guide's hydraulic oil and arrive secondary valve, then by electric control handle by controller output pwm signal to the electric proportional valve of pair valve, by electric ratio
Example valve electromagnetism actuation acts on the switch to be formed and opens guide's hydraulic oil, and the pressure that guide's hydraulic oil is formed opens the high pressure of secondary valve
Oil duct makes high pressure oil enter oil cylinder and is formed simultaneously circuit, controls the operation of the flexible carry out mast of oil cylinder.
Existing rotary drilling rig control mast uses load-sensitive valve mostly, and flow difference is big, range 15L/min-
150L/min forms a degree of energy waste so that the traffic requirement to pump is larger.
Utility model content
In order to overcome problems of the prior art, the utility model provides a kind of rotary digging driller mast control device.
The utility model adopts the technical scheme that achieve the above object: a kind of rotary digging driller mast control device,
Be characterized in: main pump connects BYQ018 control valve by high pressure liquid pressure oil flowline, and BYQ018 control valve is gone out by low-pressure hydraulic oil
Oil pipe connects hydraulic oil container, and hydraulic oil container connects main pump, thus forming circuit one；The electric proportional valve of BYQ018 control valve passes through control
The pwm signal of device output processed connects and is controlled by electric control handle or touch screen displays, is beaten by electric proportional valve electromagnetic force spool
The high-pressure oil duct of BYQ018 control valve is opened, high-pressure and hydraulic oil duct connects mast oil cylinder by oil cylinder oil inlet pipe, and mast oil cylinder passes through
Oil cylinder flowline for conveying low-pressure hydraulic oil connects BYQ018 control valve, so that forming circuit two, controls mast oil cylinder
The flexible control operation for carrying out mast.
The flow design of the BYQ018 control valve is 10L/min.
The high pressure hydraulic oil of the utility model main pump output waits valve block oil circuit to connect to BYQ018 control valve.By electricity
Handle or display are controlled by the electric proportional valve of controller output pwm signal to BYQ018 control valve, by electric proportional valve electromagnetic force
The high-pressure oil duct that spool opens BYQ018 control valve is acted on, high pressure oil is made to enter oil cylinder, oil cylinder output low pressure oil is controlled through BYW018
Valve processed returns to hydraulic oil container, reduces electric control guide oil in original secondary valve and controls high-pressure oil passage by guide oil, avoids simultaneously
Due to the excessive bring energy waste of valve body flow difference.
