[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides an automated upper and lower drill rod manipulator and a drill rod bracket for a horizontal directional drilling rig, which has the following beneficial effects:

[0016] 1. The horizontal directional drilling rig has automated upper and lower drill rod manipulators and drill rod brackets. The upper and lower support arms, telescopic arms and connecting arms can be controlled by existing hydraulic devices, so that the mechanical claw can be controlled to move. At the same time, the existing hydraulic device can be used to control the mechanical claw to grab objects. In this way, the mounting plate is set on the vehicle, which can be quickly transferred. When placing the drill rod, the hydraulic system can be used to control the mechanical claw to move up and down, forward and backward, grab and release. At the same time, the placed drill rod can be dragged by the arc-shaped support plate, which further facilitates the installation of the drill rod, thereby improving work efficiency.

[0017] 2. The horizontal directional drilling rig automates the upper and lower drill rod manipulators and the drill rod bracket. By adjusting the extension and retraction of the power rod of the oil cylinder, the mechanical gripper can be driven to rotate back and forth, so that the angle of the mechanical claw can be adjusted back and forth, making it more convenient to grab the drill rod placed on the ground, thus improving the practicality of the device.

[0018] 3. The horizontal directional drilling rig has automated upper and lower drill rod manipulators and drill rod brackets. The movable plate and the movable block can be moved back and forth to adjust their positions through four rotating wheels. At the same time, the two arc-shaped brackets can be moved as the horizontal directional drill is rotated and driven forward and backward to avoid blocking the rotation and movement of the horizontal directional drill.

[0019] 4. The horizontal directional drilling rig automates the upper and lower drill rod manipulators and the drill rod bracket. After the horizontal directional drill is rotated and driven forward to resist the moving block, the moving block can be driven to move forward together. When the horizontal directional drill is rotated and driven to move backward to return to its original position, the two connecting columns can be driven to move backward through the two limit frames and the two limit blocks, so that the moving block can be driven to move backward. At the same time, the limit of the protrusion and the square plate can prevent the moving block from moving too far backward due to inertia and being unable to support the placed drill rod. In this way, it can automatically return to its original position for use on the lower side without blocking the rotation drive of the horizontal directional drill.

[0020] 5. The horizontal directional drilling rig automates the upper and lower drill rod manipulators and the drill rod bracket. By moving the moving plate backward, it can drive the corresponding two rotating wheels to move backward. When the rotating wheels move to the two lifting plates, they will be blocked by the two baffles and stop moving, so that the user can easily return the front arc-shaped support plate to its original position.

[0021] 6. The horizontal directional drilling rig has automated upper and lower drill rod manipulators and drill rod brackets. When the horizontal directional drill is driven forward by rotation, it will first push the moving block forward, which will drive the two round rods forward, thereby driving the two vertical blocks forward. When the two vertical blocks move to the bottom of the two lifting frames respectively, the moving block will drive the moving plate forward, so that when the two rotating wheels in front are separated from the lifting plate, they will move downward, so that the two lifting frames will be respectively sleeved on the two vertical blocks. In this way, when the horizontal directional drill is driven backward by rotation, it will drive the two lifting frames to move backward, thereby driving the moving plate to move backward. When the two moving wheels in front move to the lifting plate, the vertical block will be separated from the lifting frame, so that the two arc-shaped support plates can be restored to their original positions when the horizontal directional drill is driven backward by rotation.

[0022] 7. The horizontal directional drilling rig has automated upper and lower drill rod manipulators and drill rod brackets. The placed drill rods can be further guided by inclined bars. At the same time, a number of rotating columns can reduce the friction between the drill rod and the arc-shaped support plate after the drill rod is placed. At the same time, dust and other impurities entering the arc groove can be discharged through the through groove.

[0023] 8. The horizontal directional drilling rig has automated upper and lower drill rod manipulators and drill rod brackets. Through the toughness of the pressure spring b, it can perform buffering when placing the drill rod, thereby avoiding excessive impact force when the drill rod falls. At the same time, when the lifting box moves downward to the moving block or moving plate, it will be blocked and stop moving, thereby providing buffering while avoiding the connection with the horizontal directional drilling rotary drive affected by inappropriate drill rod height.

The rotating wheels 38 on the two support bars 23 are arranged above the movable plate 3. The moving plate 14 and the moving block 12 can be moved back and forth to adjust the position through the four rotating wheels 38. At the same time, the two arc-shaped supporting plates 10 can be moved when the horizontal directional drill rotating drive 5 moves forward and backward to avoid blocking the movement of the horizontal directional drill rotating drive 5. The two support bars 2 The two sides away from each other are fixedly installed with connecting columns 57, and the two connecting columns 57 are fixedly installed with limit bars 25, and the two limit bars 25 are movably sleeved with limit frames 36, and the two limit frames 36 are fixedly connected to the horizontal directional drilling rotation drive 5, and the rear ends of the two limit bars 25 are fixedly installed with limit blocks 37, and the upper sides of the two long plates 26 are fixedly installed with square plates 24, and the front sides of the two square plates 24 are provided with protrusions 39, and the two protrusions 39 are respectively fixedly connected with the half-frame blocks 22 on the two support bars 23. After the horizontal directional drilling rotation drive 5 moves forward to abut against the moving block 12, the moving block 12 can be driven to move forward together. When the horizontal directional drilling rotation drive 5 moves backward to return to its original position, the two limit frames 36 and the two limit blocks 37 can be used to To drive the two connecting columns 57 to move backward, so that the moving block 12 can be driven to move backward.

The four half-frame blocks 22 are fixedly connected to the two lifting bars 50 and the two support bars 23 respectively. By moving the moving plate 14 backward, the corresponding two rotating wheels 38 can be driven to move backward. When the rotating wheels 38 move to the two lifting plates 51, they will be blocked by the two baffles 40, so that they will stop moving. In this way, it is convenient for the user to return the front arc-shaped support plate 10 to its original position. The rear sides of the two lifting bars 50 are fixedly installed with lifting frames 49, and the sides of the support bars 23 that are away from each other are fixedly installed with round rods 41. Vertical blocks 42 are fixedly installed on the two round rods 41. By rotating the drive 5 forward through the horizontal directional drill, the moving block 12 will be pushed forward first.This will drive the two round rods 41 to move forward, thereby driving the two vertical blocks 42 to move forward. When the two vertical blocks 42 move to the bottom of the two lifting frames 49 respectively, the moving block 12 will drive the moving plate 14 to move forward, so that the two rotating wheels 38 in front will move downward after separating from the lifting plate 51, so that the two lifting frames 49 will be respectively sleeved on the two vertical blocks 42. In this way, when the horizontal directional drill rotation drive 5 moves backward, it will drive the two lifting frames 49 to move backward, thereby driving the moving plate 14 to move backward. When the two moving wheels 38 in front are separated from the lifting plate 51, the moving plate 14 will move backward. After the vertical block 42 is moved to the lifting plate 51, the vertical block 42 will be separated from the lifting frame 49, so that the two arc-shaped support plates 10 can be restored to their original positions when the horizontal directional drilling rotary drive 5 moves backward.

The lower ends of the four pressure springs b56 are respectively connected to the moving block 12 and the moving plate 14. Through the toughness of the pressure springs b56, buffering can be performed when placing the drill rod, thereby avoiding excessive impact force when the drill rod falls. At the same time, when the lifting box 53 moves downward to the moving block 12 or the moving plate 14, it will be blocked and stop moving, thereby preventing the inappropriate height of the drill rod from affecting the connection with the horizontal directional drilling rotation drive.

[0038] When in use, the first step: the upper and lower support arms 7, the telescopic arms 27 and the connecting arms 28 can be controlled by the existing hydraulic device, so that the mechanical claw 29 can be controlled to move, and the existing hydraulic device can be used to control the mechanical claw 29 to grab objects, so that the mounting plate 1 is set on the vehicle and can be quickly transferred. When placing the drill rod, the hydraulic system can be used to control the mechanical claw 29 to move up and down, front and back, grab and release. At the same time, the placed drill rod can be dragged by the arc-shaped support plate 10, thereby further facilitating the installation of the drill rod, thereby improving work efficiency.

[0039] Step 2: By adjusting the extension and retraction of the power rod of the lead screw 32, the mechanical gripper 29 can be driven to rotate and move back and forth, so that the angle of the mechanical gripper 29 can be adjusted back and forth, so that the drill rod placed on the ground can be grasped more conveniently, thereby improving the practicality of the device.

[0040] Step 3: The four rotating wheels 38 can be used to move the moving plate 14 and the moving block 12 back and forth to adjust their positions. At the same time, the two arc-shaped supporting plates 10 can be moved as the horizontal directional drill rotary drive 5 moves forward and backward to avoid blocking the movement of the horizontal directional drill rotary drive 5.

[0041] Step 4: After the horizontal directional drill rotary drive 5 moves forward and presses against the moving block 12, the moving block 12 can be driven to move forward together. When the horizontal directional drill rotary drive 5 moves backward to return to its original position, the two connecting columns 57 can be driven to move backward through the two limit frames 36 and the two limit blocks 37, so that the moving block 12 can be driven to move backward. At the same time, the positioning of the protrusion 39 and the square plate 24 can prevent the moving block 12 from moving too far backward due to inertia and being unable to support the placed drill rod. In this way, it can automatically return to its original position for use on the lower side without blocking the movement of the horizontal directional drill rotary drive 5.

[0042] Step 5: By moving the movable plate 14 backward, the corresponding two rotating wheels 38 can be driven to move backward. When the rotating wheels 38 move to the two lifting plates 51, they will be blocked by the two baffles 40 and stop moving, so that the user can easily return the front arc-shaped support plate 10 to its original position.

[0043] Step 6: When the horizontal directional drilling rotation drive 5 moves forward, the moving block 12 will be pushed forward first, which will drive the two round rods 41 to move forward, thereby driving the two vertical blocks 42 to move forward. When the two vertical blocks 42 move to the bottom of the two lifting frames 49 respectively, the moving block 12 will drive the moving plate 14 to move forward, so that when the two rotating wheels 38 in front are separated from the lifting plate 51, they will move downward, so that the two lifting frames 49 will be respectively sleeved on the two vertical blocks 42. In this way, when the horizontal directional drilling rotation drive 5 moves backward, it will drive the two lifting frames 49 to move backward, thereby driving the moving plate 14 to move backward. When the two moving wheels 38 in front move onto the lifting plate 51, the vertical block 42 will be separated from the lifting frame 49, so that the two arc-shaped support plates 10 can be restored to their original positions when the horizontal directional drilling rotation drive 5 moves backward.

[0044] Step 7: The placed drill rod can be further guided by the inclined strip 9, and the friction between the drill rod and the arc-shaped support plate 10 can be reduced by a plurality of rotating columns 44 after the drill rod is placed, and the dust and other impurities entering the arc-shaped groove 46 can be discharged by the through groove 43.

[0045] Step 8: Through the toughness of the pressure spring b56, buffering can be performed when placing the drill rod, thereby avoiding excessive impact force when the drill rod falls. At the same time, when the lifting box 53 moves downward to the moving block 12 or the moving plate 14, it will be blocked and stop moving, thereby providing buffering while avoiding the inappropriate height of the drill rod affecting the connection with the horizontal directional drill rotation drive.
