[0023] The rod delivery device 5 includes a shuttle arm 14 and a gripper 15. The gripper 15 is used to grab the drill rod 7. The gripper 15 is arranged at the end of the shuttle arm 14, and the shuttle arm 14 is arranged vertically with the drill frame 8. The shuttle arm 14 is used for telescopic movement, so that the gripper 15 reciprocates between the two points of the loading and unloading rod position and the drill rod box 6. The power device of the shuttle arm 14 is a motor or a cylinder. The shuttle arm 14 is provided with a shuttle arm encoder 12, and the specific position of the shuttle arm 14 can be determined by reading the number of pulses of the shuttle arm encoder 12.

When the encoder reset limiter 13 senses the limit, the pulse count of the shuttle arm encoder 12 is reset to zero, thereby eliminating the cumulative error caused by the reciprocating motion of the shuttle arm. The shuttle arm 14 is equipped with an anti-collision limiter 11. When the limit is sensed, the power head shall not continue to push forward beyond the safe area to prevent the power head from moving beyond the safe area and crashing the shuttle arm 14 and the gripper 15.

[0025] The operating unit of the control system includes: a drill rod box selection knob, a display and an operating handle; the traditional method of manually plugging and unplugging the pin shaft to change the number of drill rod boxes is improved to a selection knob panel, which switches the number of columns through the panel and automatically locks the retracted stop position of each column shuttle arm in conjunction with the encoder; the real-time position of the power head on the drill frame and the number of columns currently selected by the drill rod box can be visually observed on the display; the operating handle is provided with operating components for retracting the shuttle arm 14, lifting the jacking device 2, and tightening and loosening the gripper 15. The control command of the operating handle is sent back to the controller 110 as an input signal; the controller 110 outputs the output command to each unit after a series of calculations and logical judgments; Controller 110 is the core control element, and the input end: the power head position sensor input terminal 101 is connected to the 213 and 208 pins of the controller 110 and the positive power supply; the anti-collision limiter input terminal 102, the rising limiter input terminal 103, the falling limiter input terminal 104 and the shuttle arm encoder reset limit input terminal 105 are respectively connected to the 138, 168, 218 and 229 pins of the controller 110 and the ground wire; the encoder is a double pulse and is respectively connected to the 255, 133, 132 and 146 pins of the controller 110; the display is connected to the bus CAN1 of the controller 110 and a 120Ω resistor is connected between the two CAN lines; the operating handle and the drill rod box selection knob are connected to the bus CAN2 of the controller 110 and a 120Ω resistor is connected between the two CAN lines.

Example

[0027] This embodiment provides a control method for the control system of the drilling rod loading and unloading device described in Embodiment 2, including the following process: When the column selection knob panel is operated to select the column number, the control system will automatically determine the specific position of the shuttle arm retracting according to the selected column number. During the retracting process of the shuttle arm, if it detects that it has reached the stop area, it will stop the action output and close the shuttle arm retracting solenoid valve. In addition, a deceleration area is set during the retracting process of the shuttle arm to reduce the inertia of the shuttle arm when it retracts, preventing the problem of inaccurate final stop position caused by inertia.

[0028] Automatic loading and unloading of drill rods only requires two signals from the operating handle, one is the automatic extension of the shuttle arm, and the other is the automatic retraction of the shuttle arm; these two signals are divided into 4 operating states, among which the automatic extension of the shuttle arm is divided into two states: sending the rod and emptying, and the automatic retraction of the shuttle arm includes two states: unloading the rod and emptying. The control system determines the execution logic of subsequent actions based on the real-time position of the power head and the input signal of the operating handle.

[0029] First, each action and power head position are divided into several states, as follows: The gripper action is divided into two states: gripper tightening A0 and gripper releasing A1; The shuttle arm action is divided into two states: shuttle arm extending B0 and shuttle arm retracting B1; The lifting action is divided into two states - lifting up C0 and lifting down C1; The power head position is divided into three states: the end position of the drilling rig D0, the position for loading and unloading drill rods D1, and other positions D2; A0=1 means the gripper is in the gripping state; A1=1 means the gripper is in the releasing state, and the same applies to other actions and states.

[0030] The shuttle arm automatically extends the command input, the first step is to determine the real-time position of the power head. If the power head is at the end position of the drilling rig D0=1, it is determined that the rod needs to be sent at this time, and the state is the rod sending mode. The initial state of the rod sending mode is as follows Figure 5 A0=1, B1=1, C0=1 must be satisfied, that is, the gripper is gripped, the shuttle arm is retracted, and the top is in the raised state. The second step is to determine whether the shuttle arm is in the retracted state. The number of columns currently selected and the number of pulses of the encoder can be used to determine whether the shuttle arm is in the retracted state. If it is not in the retracted state, it means that the operation is wrong and the subsequent command output is stopped; if so, the third step continues to determine whether the top is in the raised state. If both the top limit 1 and the top limit 2 are not energized, it means that the top is in the raised state. If so, the instructions are executed sequentially to make A1=1, C1=1, A0=1, B0=1 in sequence. Otherwise, the instructions are directly executed sequentially to make A0=1 and B0=1 in sequence.

[0031] The shuttle arm automatically extends the command input. If the first step determines that the power head is in the loading and unloading drill rod position D1=1, it is determined that the unloading rod state needs to be vacated at this time, which is the vacating mode. The initial state of the vacating mode is as follows: Figure 7 The initial state A0=1, B1=1, C0=1 must be satisfied, that is, the gripper is gripped, the shuttle arm is retracted, and the top is raised. At this time, the second step is to first determine whether the shuttle arm is in the retracted state. According to the currently selected column number and the number of pulses of the encoder, it can be determined whether the shuttle arm is in the retracted state. If it is not in the retracted state, it means that the operation is wrong and the subsequent command output is stopped; if so, the third step continues to determine whether the top is in the raised state. If both the top limit 1 and the top limit 2 are not energized, it means that the top is in the raised state. If so, the instructions are executed sequentially to make A1=1 and B0=1 in sequence. Otherwise, the instructions need to be executed sequentially to make A1=1, C0=0, and B0=1 in sequence.

[0032] The shuttle arm automatically retracts the command input. The first step is to determine the real-time position of the power head. If the power head is in the position of loading and unloading the drill rod D1=1, it is determined that it needs to return after loading the drill rod. The initial state of the return mode is as follows: Figure 6 The initial state A1=1, B0=1, C1=1 must be satisfied, that is, the gripper is released, the shuttle arm is extended, and the top is in the landing state. The second step is to determine whether the shuttle arm is in the extended state. If the shuttle arm clears the sensor point, it means that the shuttle arm is in the fully extended state. If not, it means that the operation input command is incorrect and the subsequent command output is stopped; if so, the third step is to determine whether the top is in the landing state. If both the top limit 1 and the top limit 2 are energized, it means that the top is in the landing state. If so, the instructions need to be executed sequentially to make C0=1, B1=1, A0=1 in sequence, otherwise the instructions are directly executed sequentially to make B1=1, A0=1 in sequence.

[0033] The shuttle arm automatically retracts the command input. If the first step determines that the force head position is at the end position of the drill frame D0=1, it is determined that the drill rod needs to be returned after being disassembled. The initial state of the return mode is as follows: Figure 8 The initial state A0=1, B0=1, C0=1 must be met, that is, the gripper is grasped, the shuttle arm is extended, and the top is raised. At this time, the second step is to determine whether the shuttle arm is in the extended state. If the shuttle arm clears the sensor point, it means that the shuttle arm is in the fully extended state. If not, it means that the operation input command is incorrect and the subsequent command output is stopped; if so, the third step is to determine whether the top is in the raised state. If both the top limit 1 and the top limit 2 are not energized, it means that the top is in the raised state. If so, it is necessary to execute the instructions in sequence to make C1=1, A0=1, B1=1, A1=1, C0=1, A0=1 in sequence, otherwise directly execute the instructions in sequence to make A0=1, B1=1, A1=1, C0=1, A0=1 in sequence.

[0034] According to the above invention, when installing the drill rod, it is only necessary to move the power head to the end position D0=1 of the power head, at which time the operating shuttle arm automatically extends, automatically determines the state of sending the rod and executes subsequent instructions; after the rod is sent, the power head moves forward to the position D1=1 for loading and unloading the drill rod, the recognition is completed, the operating shuttle arm automatically retracts, and automatically determines the empty return state to execute subsequent instructions. Similarly, when disassembling the drill rod, the power head first runs to the position D1=1 for loading and unloading the drill rod, at which time the operating shuttle arm automatically extends, automatically identifies the empty mode for disassembling the drill rod and executes subsequent instructions, and after the unloading is completed, the power head moves back to the end position D0=1 of the power head, the operating shuttle arm automatically retracts, and automatically determines the state of returning the rod and executes subsequent instructions.
