Detailed Description of the Embodiments
With reference to the figure of the present invention, a clear and complete description of the present invention is further given below.
Fig. 1 is an embodiment of a control system of a rotary drilling rig according to the present invention, comprising a power switch 1, a battery 2, a transmitter 3, a receiver 4 and a group of proportional valves. The group of proportional valves are capable of regulating a speed of an action of rotary drilling rig. A negative electrode of the battery 2 is grounded through the power switch 1. A positive electrode of the battery 2 is connected to of a power supply terminal of the receiver 4. The transmitter 3 and the receiver 4 are connected with each other via real-time radio frequency communication or CAN bus communication. The transmitter 3 is able to send PWM signal to the receiver 4. PWM output ports of the receiver 4 are connected to the group of proportional valves. When manipulating an action joystick on the transmitter 3, the transmitter 3 sends a command signal to the receiver 4 via the radio frequency or CAN bus. For example, when manipulating a pressure-lifting joystick on the transmitter 3, the receiver 4 sends a corresponding PWM signal to at least one port in its 4 to 11 ports according to a received command signal. A PWM signal output from the receiver’s 8th port controls an action of a corresponding proportional valve, whereby the pressure cylinder of rotary drilling rig makes the lifting. Such an operation can remotely control major actions of the rotary drilling rig, and the machine can be operated even without an operator in the driver’s cab.
The receiver 4 comprises a wireless remote control interface and a CAN bus interface such that the control system is able to switch between the radio frequency communication and the CAN bus communication.
In order to switch between control in a driver’s cab and a remote control, an electric proportional hydraulic pilot control system is added to the hydraulic system which corresponding to cab control mode. The electric proportional hydraulic pilot 4 control system is connected in parallel with the cab control mode hydraulic pilot valve and connected therewith by a hydraulic shuttle valve group. The two systems are supplied with oil by a single pilot pump, which enables the two control systems to control the rotary drilling rig independently. In the electric proportional hydraulic pilot control system, the group of electrical proportion valves are controlled by a wired or wireless remote control system. Through the control of the remote control system, major functions of the rotary drilling rig can be implemented.
As shown in Fig. 1, the group of proportional valves comprising a proportional valve 5 for turning an upper portion to the left, a proportional valve 6 for turning an upper portion to the right, a proportional valve 7 for crawler forward moving, a proportional valve 8 for crawler backward moving, a proportional valve 9 for lifting a pressure cylinder, a proportional valve 10 for lowering a pressure cylinder, a proportional valve 11 for turning a power head to the left, and a proportional valve 12 for turning the power head to the right. A corresponding control may be implemented according to the specific feature of the group of proportional valves.
For better implementation of the control, the proportional valve 5 for turning an upper portion to the left, the proportional valve 6 for turning an upper portion to the right, the proportional valve 7 for crawler forward moving, the proportional valve 8 for crawler backward moving, a proportional valve 9 for lifting a pressure cylinder, the proportional valve 10 for lowering a pressure cylinder, the proportional valve 11 for turning the power head to the left, and the proportional valve 12 for turning the power head to the right are electromagnetic proportional valves.
For convenient operation, the transmitter 3 comprises a control device which regulates a speed of an action of the rotary drilling rig.
Specifically, the control device comprising a linear joystick, by controlling an amplitude of which, a value of a command signal from the transmitter 3 can be adjusted, so as to control the group of proportional valves through the receiver 4 and to further regulate a speed of an action of the rotary drilling rig.
For safety consideration, the receiver 4 further comprising a ground terminal. 5
As required for actual working condition, the real-time radio frequency communication has a distance in range of 100 to 150 m.
Considering the effective transmission distance of the CAN bus communication, the CAN bus communication has a distance of about 50 m. This system uses an all-digital micro-power high-frequency wireless receiving & transmitting device, which supports multiple frequency segments and has an effective working range up to 100 to 150 m. In order to prevent strong electromagnetic interference on the construction site from causing unavailable radio frequency, there is further provided with a standby wired operation solution having a working range up to 50 m.
The present invention further provides a control method for the control system as described above, comprising: sending a command signal from the transmitter 3 to the receiver 4 via real-time radio frequency communication and/or CAN bus communication; and sending a PWM signal from the receiver 4 to the group of proportional valves via the PWM output port according to the received command signal.
For convenient mode selection, before sending a command signal from the transmitter 3 to the receiver 4 via the real-time radio frequency communication and/or the CAN bus communication, further comprising: selecting a communication mode from the radio frequency communication and the CAN bus communication.
The control device comprising a linear joystick, by controlling an amplitude of which, a value of a command signal from the transmitter 3 can be adjusted, so as to control the group of proportional valves through the receiver 4 and to further regulate a speed of an action of the rotary drilling rig.
Take pressure-lifting as an example, a detailed description of the operation process is given below: when pressure-lifting joystick of the transmitter 3 is manipulated, the transmitter 3 sends a command signal, the receiver 4 sends a corresponding PWM signal to the 8th port of the receiver 4 according to the received command signal. The PWM signal output from the receiver’s 8th port controls an action of the pressure-lifting proportional valve whereby the pressure cylinder of the 6 rotary drilling rig makes the lifting. Other actions each has a similar operation process. Such an operation can remotely control major actions of the rotary drilling rig. The Machine can be operated even without an operator in the driver’s cab. Manipulation of other electromagnetic valves are similar to the above.
Besides, the present invention also provides a rotary drilling rig, comprising said control system.
