Fuel tank, motor are failure to actuate, and by increase small flame-proof intrinsically safe programmable control box, provide the control system of the device, will
Existing rig design is the conversion of " operating mode " and " debugging mode " both of which.When drilling machine is in " operating mode ", lead to
The programming of PLC sentence logic is crossed, setting pressure threshold value such as 0.1MPa, which is used as drilling machine, in program allows the water of bore operation
Precondition is pressed, i.e., when pressure sensor detects that hydraulic pressure reaches setting value such as 0.1MPa, PLC control cabinet passes through intermediate relay
Movement obtains electric, makes hydraulic oil normal through motor, realize positive and negative rotation movement, complete bore operation to control electro-hydraulic reversing valve,
When setting value is not achieved in hydraulic pressure, electro-hydraulic reversing valve must not be electric, and motor is failure to actuate without fuel feeding, that is, is unable to complete bore operation.When
When drilling machine is in " debugging mode ", hydraulic pressure, which detects, is not re-used as the necessary condition of drill hole of drilling machine, electro-hydraulic reversing valve always electric, horse
Up to regular event, it is therefore an objective to which convenient for debugging and upkeep operation, double mode design has rights management, and programmable control box is set
Vertical outer protection cover, key open the administrative staff for transferring to repair or specify, and rig operations work does not have the permission, bore to meet
Machine normal drill operation demand, equipment damage or scene harm, design research and development pass through increasing caused by avoiding because of artificial unreasonable operation
Add small-sized electrichydraulic control equipment that existing drill hole of drilling machine operation is increased barring condition, realizes that drilling machine is filled the water and passed only carrying out
When sensor detects hydraulic pressure, drilling machine can carry out bore operation, otherwise not allow drilling operation.
It in the technical scheme, is the underground drill rig device noumenon of basic signal with water-flow signal, the first main part, the second master
Part and controller are important technical characteristic, are limiting underground drill rig device and drilling side that fire explosion occurs based on forcing to spray water
In the technical field of method, there is novelty, creativeness and practicability, term in the technical scheme is all that can use this technology
Patent document in field explains and understands.
