Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drilling rig drill rod disassembly, in particular to a full-automatic tunnel drilling rig drill rod automatic loading and unloading system. Background Art

[0002] Tunnel drilling rigs are widely used in mining, tunnel construction and other engineering fields for geological exploration, tunnel excavation and other operations. During these operations, the loading and unloading of drill rods is a frequent and important step. Traditionally, the loading and unloading of drill rods is mainly done manually, which is not only labor-intensive and inefficient, but also poses safety risks. Especially under complex geological conditions, the difficulty and danger of manual loading and unloading of drill rods are further increased.

[0003] In order to improve the efficiency and safety of drill pipe loading and unloading, a variety of automated and semi-automated drill pipe loading and unloading systems have emerged in recent years. However, these systems often have problems such as complex structure, cumbersome operation, and poor adaptability, making them difficult to be widely used in actual projects. Therefore, there is a need for a system with a simple structure, easy operation, strong adaptability, and the ability to fully automatically complete drill pipe loading and unloading operations. Utility Model Content

[0004] The technical problem to be solved by the utility model is to address the deficiencies of the existing technology and provide a fully automatic tunnel drilling rig drill rod automatic loading and unloading system that automatically disassembles drill rods without the need for manual disassembly, and maximizes the efficiency of drill rod loading and unloading while protecting the equipment from human damage.

[0005] The technical problem to be solved by the utility model is achieved through the following technical solutions: a fully automatic tunnel drilling rig drill rod automatic loading and unloading system, the automatic loading and unloading system includes a disassembly assembly and a pick-up and placement assembly;

[0006] The disassembly assembly includes a frame, on the top of which is provided a track module for the hydraulic chuck power head to move, the track module being arranged horizontally, and on the track module are sequentially provided a starting position detection point, a retreat position detection point, a shackle completion detection point, and a drill rod pick-up and placement point by a manipulator along the entry direction of the drill rod, and a drill rod clamp for clamping the outer peripheral surface of the drill rod is fixedly installed on the top of the frame near the starting position detection point;

[0007] The pick-and-place assembly is arranged on the side of the frame. The pick-and-place assembly includes a manipulator for taking out the drill rod from the hydraulic chuck power head on the track module or placing the drill rod into the hydraulic chuck power head on the track module. A drill rod box for accommodating the drill rod is also provided under the frame between the manipulator and the track module.

[0008] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. In the above-mentioned fully automatic tunnel drilling rig drill rod automatic loading and unloading system, the starting position detection point, the retreat position detection point, the shackle completion detection point and the manipulator drill rod picking and placing point are travel limiters respectively installed on the top of the frame.

[0009] The technical problem to be solved by the present invention can also be achieved through the following technical solutions: in the above-mentioned fully automatic tunnel drilling rig drill rod automatic loading and unloading system, the center of the clamping end of the clamper is concentric with the center of the hydraulic chuck and parallel to the installation direction of the track module.

[0010] Compared with the existing technology, the beneficial technical effects of the present invention are: the system can fully automatically complete the disassembly and drilling operations of the drill rod, greatly reducing manual intervention and improving work efficiency. At the same time, since the system is easy to operate, the labor intensity of the operator is also reduced; in addition, since the system is operated automatically, the operator is prevented from directly contacting the drill rod and the drilling rig, which means that the risk of accidents is fundamentally reduced and the safety of the operation is enhanced.

[0014] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0015] Example 1, with reference to Figure 1 , a fully automatic tunnel drilling rig drill rod automatic loading and unloading system, the automatic loading and unloading system includes a disassembly assembly and a pick-up and placement assembly;

[0016] The disassembly assembly includes a frame 1, which can be made of overlapped and welded profiles. Its size can be customized according to the use requirements. A track module 2 for the hydraulic chuck power head to move is provided on the top of the frame 1. The track module 2 includes a track and a slider. The top surface of the slider is used to support the hydraulic chuck 3 power head 12.

[0017] The length of the track module 2 can be selected according to the use requirements. The track module 2 is arranged horizontally. A starting position detection point 4, a retreat position detection point 5, a shackle completion detection point 6 and a manipulator pick-up and placement drill rod point 7 are sequentially arranged on the track module 2 along the entry direction of the drill rod 11. The starting position detection point 4, the retreat position detection point 5, the shackle completion detection point 6 and the manipulator pick-up and placement drill rod point 7 are travel limiters respectively installed on the top of the frame 1. A drill rod clamp 8 for clamping the outer peripheral surface of the drill rod 11 is fixedly installed on the top of the frame 1 near the starting position detection point 4. The center of the clamping end of the drill rod clamp 8 is parallel to the installation direction of the track module 2;

[0018] The pick-and-place assembly is arranged on the side of the frame 1, and the pick-and-place assembly includes a manipulator 9 for taking out the drill rod 11 from the hydraulic chuck 3 power head 12 on the track module 2 or placing the drill rod 11 into the hydraulic chuck 3 power head 12 on the track module 2. A drill rod box 10 for accommodating the drill rod 11 is also provided under the frame 1 between the manipulator 9 and the track module 2. The drill rod box 10 is formed into a roughly square box structure.

[0019] The use process of the automatic tunnel drilling rig drill rod automatic loading and unloading system is as follows:

[0020] (1) Disassembly of drill pipe:

[0021] When removing drill rods 11, the total number of drill rods to be removed is first set. The power head 12 is then manually moved to the starting position detection point 4. The rocker (operating handle) on the control panel (which can be externally mounted depending on the model of the power head 12 and hydraulic chuck 3, and customized program specifications) is then moved to the drill rod removal position. This initiates the fully automated drill rod removal cycle. The hydraulic chuck 3 clamps the outer circumference of the drill rod 11, followed by the clamp 8 opening. The power head 12 rapidly moves the drill rod to the reverse limit detection point. Clamp 8 tightens, and the power head 12 reverses and simultaneously moves backward to the shackle completion detection point 6. At this point, the first drill rod is shackled. The manipulator 9 removes the removed drill rod and places it in the drill rod box 10. The hydraulic chuck 3 then opens, and the power head 12 automatically and rapidly moves to the starting position detection point to automatically remove the second drill rod. This cycle repeats until all drill rods have been removed, completing the automated drill rod removal process.

[0022] (2) Lowering the drill pipe:

[0023] When lowering a drill rod 11, the total number of rods to be lowered is set. The power head 12 is then manually moved to the starting position detection point 4. The joystick on the control panel is then pushed down to the rod position, and the fully automatic drill rod lowering cycle begins. First, the gripper 8 is tightened, and the manipulator 9 removes the rod from the drill rod box 10 and places it in the pre-set position. The hydraulic chuck 3 then opens, and the power head 12 rapidly moves to the reverse limit detection point. The hydraulic chuck 3 then tightens, and the manipulator 9 withdraws and removes a rod from the drill rod box 10. The power head 12 then rotates forward while simultaneously advancing until the rod is tightened. The gripper 8 then opens, and the power head 12 rapidly moves the rod to the starting limit detection point 4, stopping. The gripper 8 then tightens, completing the lowering of the first rod. This operation (lowering the rod) is repeated for each rod 11 until the set number of rods has been completed, at which point the automatic lowering process is complete.
