Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and specifically to a deep hole multi-angle drilling equipment with automatic anchor bolt loading and unloading. Background Technology

[0002] In geotechnical engineering fields such as mining, tunnel excavation, and slope reinforcement, deep-hole anchor bolt support is a core technology to ensure the stability of engineering structures and construction safety. Its construction quality and efficiency directly determine the overall progress and safety level of the project.

[0003] Currently, deep hole drilling equipment on the market relies heavily on manual operation for loading and unloading drill rods. This not only results in high labor intensity and low work efficiency but also makes the drill rods prone to misalignment due to human error, affecting support quality. Furthermore, manual intervention in confined spaces poses significant safety hazards. Therefore, to address these issues, improve the efficiency and quality of drilling equipment, and reduce losses, this invention has been developed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a deep-hole multi-angle drilling device with automatic anchor bolt loading and unloading, comprising: a drilling rig body and a drill rod. The outer wall of the mechanical arm of the drilling rig body is fixedly connected to a loading and unloading structure, which includes a positioning structure, a rod-changing structure, and a storage structure. The loading and unloading structure includes a support plate, the outer wall of which is fixedly connected to the outer wall of the positioning structure. A rotating motor is fixedly connected to the outer wall of the support plate, and a support frame is fixedly connected to the output shaft of the rotating motor. A hydraulic rod is fixedly connected to the outer wall of the support frame, and a connecting block is rotatably connected to the end of the output shaft of the hydraulic rod. A first clamping block is rotatably connected to the end of the connecting block away from the hydraulic rod, and a second clamping block is provided on the opposite side of the first clamping block. Notably, the drilling rig body is equipped with an intelligent control module, which can automatically control the equipment to complete the entire process from positioning, hole drilling, automatic rod connection and drilling, and automatic rod retraction and unloading, ensuring the cooperation between the various structures.

[0005] Preferably, the outer wall of the support frame is rotatable to the inner wall of the support plate, the outer wall of the first clamping block is rotatably connected to the inner wall of the support frame, and the outer wall of the second clamping block is fixedly connected to the outer wall of the support frame.

[0006] Preferably, the positioning structure includes a guide plate, the bottom of which is fixedly connected to the top of the mechanical arm of the drilling rig body.

[0007] Preferably, a positioning machine is slidably connected to the outer wall of the guide plate, and a stabilizing block is fixedly connected to the top of the guide plate. The drill rod passes through the stabilizing block. It is worth noting that the positioning machine ensures the coaxiality of the loading and unloading structure, the power head and the drill rod when they are connected through an external power device and a vision sensor, laser rangefinder or physical alignment device, and at the same time realizes the automatic and reliable screwing and unscrewing of the drill rod thread.

[0008] Preferably, the storage structure includes a fixing frame, the bottom of which is fixedly connected to the outer wall of the guide plate.

[0009] Preferably, an adjusting plate is fixedly connected to the outer wall of the fixing frame, and a snap-fit ​​plate is rotatably connected to the inner wall of the adjusting plate. The outer wall of the snap-fit ​​plate has eight sets of snap-fit ​​grooves, and the inner diameter of the snap-fit ​​grooves matches the diameter of the drill rod. The adjusting plate controls the rotation of the snap-fit ​​plate through external power. When the loading and unloading structure completes the installation or disassembly of the drill rod, after the loading and unloading structure snaps the drill rod into or removes it from the snap-fit ​​plate, the adjusting plate drives the snap-fit ​​plate to rotate, driving the new drill rod to the designated work position or the reserved installation space for easy installation or disassembly next time.

[0010] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a loading and unloading structure and a rod changing structure, allows the rotating motor to drive the support frame to rotate around the support plate, and in conjunction with the hydraulic rod to drive the opening and closing of the first clamping block and the second clamping block, so as to flexibly clamp the drill rod and adjust the angle, adapt to the construction requirements of deep hole multi-angle drilling, and replace manual loading and unloading of the drill rod.

[0011] 2. This invention, through its storage structure, features a locking plate with eight locking slots matching the diameter of the drill rod, enabling the orderly storage of idle drill rods. A fixing frame ensures the overall stability of the storage structure. An adjusting plate, driven by external power, rotates the locking plate. After the loading and unloading structure completes the loading and unloading of the drill rod, it automatically transfers the new drill rod to a designated workstation or a reserved empty slot. This design solves the problems of disorganized drill rod placement and the need for manual handling and positioning during rod replacement in existing equipment, shortening the rod replacement cycle, achieving efficient drill rod turnover, and ensuring the continuity of drilling operations.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0015] Example: Please see Figure 1 - Figure 2This invention provides a technical solution: a deep-hole multi-angle drilling device with automatic anchor bolt loading and unloading, comprising: a drilling rig body 1 and a drill rod 3. The outer wall of the mechanical arm of the drilling rig body 1 is fixedly connected to a loading and unloading structure 2. The loading and unloading structure 2 includes a positioning structure 21, a rod-changing structure 22, and a storage structure 23. The loading and unloading structure 2 includes a support plate 221. The outer wall of the support plate 221 is fixedly connected to the outer wall of the positioning structure 21. A rotary motor 222 is fixedly connected to the outer wall of the support plate 221. The output shaft of the rotary motor 222 is fixedly connected to a support frame 223. A hydraulic rod 224 is fixedly connected to the outer wall of the support frame 223. A connecting block 2 is rotatably connected to the end of the output shaft of the hydraulic rod 224. 25. A first clamping block 226 is rotatably connected to the end of the connecting block 225 away from the hydraulic rod 224. A second clamping block 227 is provided on the opposite side of the first clamping block 226. The outer wall of the support frame 223 rotates with the inner wall of the support plate 221. The outer wall of the first clamping block 226 is rotatably connected with the inner wall of the support frame 223. The outer wall of the second clamping block 227 is fixedly connected with the outer wall of the support frame 223. When the intelligent control module of the drilling rig body 1 is activated, the module automatically commands the loading and unloading structure 2 to operate. The output shaft of the hydraulic rod 224 extends and retracts, driving the connecting block 225 to move, thereby driving the first clamping block 226 to open and close relative to the second clamping block 227, realizing the clamping or releasing of the drill rod 3. When it is necessary to change the rod, the rotating motor 222 drives the support frame 223 to rotate around the support plate 221, adjusts the clamping angle, and cooperates with the positioning structure 21 to accurately connect the drill rod 3 to the power head or place it in the storage structure 23. The entire process is coordinated by an intelligent control module, which automatically completes the positioning, drilling, rod extension drilling, rod retraction and unloading processes, ensuring the continuity and accuracy of the operation.

[0016] Please see Figure 3 The positioning structure 21 includes a guide plate 211. The bottom of the guide plate 211 is fixedly connected to the top of the robotic arm of the drilling rig body 1. A positioning machine 213 is slidably connected to the outer wall of the guide plate 211, and a stabilizing block 212 is fixedly connected to the top of the guide plate 211. The drill rod 3 passes through the stabilizing block 212. The intelligent control module instructs the positioning machine 213 to slide along the guide plate 211 to a designated position, accurately positioning the relative position of the drill rod 3 and the loading / unloading structure 2 through a visual sensor and a laser ranging device. When the drill rod 3 passes through the stabilizing block 212, the stabilizing block 212 guides and stabilizes the drill rod 3, preventing deviation. The positioning machine 213 is further calibrated through a physical alignment device to ensure the coaxiality of the three components. When the positioning machine 213 drives the drill rod 3 to be threaded or disassembled, the positioning machine 213, in conjunction with an external power device, provides stable support, ensuring reliable threaded connections and smooth disassembly, laying the foundation for subsequent drilling or rod retraction operations.

[0017] Please see Figure 4The storage structure 23 includes a fixed frame 231. The bottom of the fixed frame 231 is fixedly connected to the outer wall of the guide plate 211. An adjusting plate 232 is fixedly connected to the outer wall of the fixed frame 231. A snap-fit ​​plate 233 is rotatably connected to the inner wall of the adjusting plate 232. The outer wall of the snap-fit ​​plate 233 has eight sets of snap-fit ​​slots. The inner diameter of the snap-fit ​​slots matches the diameter of the drill rod 3. Idle drill rods 3 are snapped into the eight sets of snap-fit ​​slots of the snap-fit ​​plate 233. The fixed frame 231 ensures the overall stability of the storage structure 23. When the loading and unloading structure 2 needs to install a drill rod, its clamping mechanism moves to the storage structure 23 and takes the target drill rod 3 away from the snap-fit ​​slot. After disassembly, the drill rod 3 is snapped into an empty snap-fit ​​slot. Then, the adjusting plate 232 drives the snap-fit ​​plate 233 to rotate under external power, transferring the new drill rod 3 to be installed to the designated docking position, or reserving an empty snap-fit ​​slot for the next disassembly, realizing the orderly storage and efficient turnover of drill rods.

[0018] Working principle: During operation, the intelligent control module of the drilling rig body 1 is activated. The module automatically commands the loading and unloading structure 2 to operate. The output shaft of the hydraulic rod 224 extends and retracts, driving the connecting block 225 to move, which in turn drives the first clamping block 226 to open and close relative to the second clamping block 227, thereby clamping or releasing the drill rod 3. When a rod needs to be changed, the rotating motor 222 drives the support frame 223 to rotate around the support plate 221, adjusting the clamping angle. In conjunction with the positioning structure 21, the drill rod 3 is precisely connected to the power head or placed in the storage structure 23. Throughout the entire process, the intelligent control module coordinates the linkage of various structures, automatically completing the entire process of positioning, drilling, rod connection drilling, and rod retraction and unloading, ensuring the continuity and accuracy of the operation. The intelligent control module commands the positioning machine 213 to slide along the guide plate 211 to the designated position, and accurately positions the relative position of the drill rod 3 and the loading and unloading structure 2 through a visual sensor and a laser ranging device. When the drill rod 3 passes through the stabilizing block 212, the stabilizing block 212 guides and stabilizes the drill rod 3, preventing deviation. The positioning machine 213 further calibrates the system using a physical alignment device to ensure the coaxiality of the three components. When the positioning machine 213 drives the drill rod 3 to be threaded or disassembled, it provides stable support in conjunction with an external power unit, ensuring reliable threaded connections and smooth disassembly, laying the foundation for subsequent drilling or rod retraction operations. Idle drill rods 3 are inserted into the eight sets of slots on the clamping plate 233, and the fixing frame 231 ensures the overall stability of the storage structure 23. When the loading / unloading structure 2 needs to install a drill rod, its clamping mechanism moves to the storage structure 23, carrying the target drill rod 3 away from the slot; after disassembly, the drill rod 3 is then inserted into an empty slot. Subsequently, the adjusting plate 232, driven by external power, rotates the clamping plate 233, transferring the new drill rod 3 to be installed to the designated docking position, or reserving an empty slot for the next disassembly, achieving orderly storage and efficient turnover of drill rods.
