Description

Technical Field

[0001] This invention belongs to the technical field of support drilling rigs, specifically referring to a mining hydraulic support drilling rig. Background Technology

[0002] As a core piece of equipment in the field of modern mine roadway support, the mining hydraulic support drilling rig integrates multiple functions such as high-precision drilling, automated anchor bolt and cable installation, and temporary support. Its hydraulic drive system can quickly complete drilling operations at different inclination angles and depths by precisely controlling the swing angle and thrust of the drill arm. Combined with an automatic loading and unloading mechanism, it realizes the mechanized installation of anchoring materials, effectively replacing the high-risk links such as drilling and installation in traditional manual support operations.

[0003] The existing hydraulic support drilling rigs for mining have the following problems: Existing mining hydraulic support drilling rigs do not have the ability to support long-extended rotating drill rods, and cannot keep the drill rod and the output end of the drilling motor in a coaxial horizontal position, causing the drill bit to swing, resulting in drilling deviation, enlargement, and rough hole walls, thereby reducing drilling efficiency. Therefore, it cannot meet the current demand for mining hydraulic support drilling rigs. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a mining hydraulic support drilling rig that can support a long-extended rotary drill rod, so that the drill rod and the output end of the drilling motor can be kept in a coaxial horizontal position, thus ensuring drilling accuracy.

[0005] The technical solution adopted in this plan is as follows: This plan proposes a mining hydraulic support drilling rig, including a chassis, moving wheels, a steering mechanism, a directional adjustment mechanism, a drilling mechanism, and a support mechanism. The moving wheels are located on both sides of the chassis. The steering mechanism includes a drive rotation assembly and a drive arm assembly. The drive rotation assembly is located at one end of the chassis, and the drive arm assembly is located at one end of the drive rotation assembly. The directional adjustment mechanism includes a lifting arm assembly and a rotating assembly. The lifting arm assembly is located at the end of the drive arm assembly away from the drive rotation assembly, and the rotating assembly is located on the side of the lifting arm assembly away from the drive arm assembly. The drilling mechanism includes a drill extension assembly, a drilling assembly, and a stabilizing assembly. The drill extension assembly is located on the side of the rotating assembly away from the lifting arm assembly, the drilling assembly is located on the drill extension assembly, and the stabilizing assembly is located at one end of the drill extension assembly. The support mechanism includes a lifting assembly and a jacking assembly. The lifting assembly is located at the end of the chassis away from the drive rotation assembly, and the jacking assembly is located at the end of the lifting assembly away from the chassis.

[0006] As a further preferred embodiment of the present invention, the drive assembly includes a steering platform and a drive motor. The steering platform is symmetrically disposed on the upper wall of one end of the chassis and is rotatably connected to the chassis. The drive motor is disposed on the bottom wall of the chassis below the steering platform, and the output end of the drive motor passes through the chassis and is connected to the steering platform. The drive arm assembly includes a drive boom and a hydraulic cylinder. The drive boom is hinged to the end of the steering platform away from the chassis, and the hydraulic cylinder is hinged between the drive boom and the steering platform.

[0007] In use, the output end of the drive motor drives the steering table to rotate, and the steering table drives the drive arm to rotate to the side away from the chassis. At this time, an angle is generated between the relatively parallel drive arms. Then, the output end of the hydraulic cylinder extends and drives the drive arm to rotate and lift along the steering table to adjust the drilling height.

[0008] Preferably, the boom lifting assembly includes a boom lifting seat, a drive arm, and a second hydraulic cylinder. The boom lifting seat is located on the bottom wall of the drive arm away from the steering table. The drive arm is hinged to the end of the drive arm near the boom lifting seat. The second hydraulic cylinder is located inside the boom lifting seat, and its end away from the boom lifting seat is hinged to the drive arm. The rotating assembly includes a rotary motor and a turntable. The rotary motor is located on the upper wall of the drive arm. The turntable is rotatably located on the side of the drive arm away from the drive arm. The output end of the rotary motor is connected to the turntable.

[0009] In use, the output end of the hydraulic cylinder extends to drive the drive arm, and the drive arm rotates along one end of the drive arm to drive the guide seat to adjust the drilling position. The rotary motor drives the turntable to rotate through the output end, and the turntable drives the drill rod to align with the drilling position through the guide seat.

[0010] Specifically, the drilling assembly includes a guide seat, a guide motor, a threaded rod, a slide rail, and a guide screw block. The guide seat is located on the side of the turntable away from the drive arm. The guide motor is located on one side of the guide seat. The threaded rod is rotatably mounted on the inner wall of the guide seat. The output end of the guide motor passes through the guide seat and connects to the threaded rod. The slide rail is located on the side of the guide seat away from the turntable. The guide screw block is located between the threaded rod and the slide rail, threadedly connected to the threaded rod and slidably connected to the slide rail. The drilling assembly includes a drilling motor and a drill rod. The drilling motor is located on the side of the guide screw block away from the guide seat. The drill rod is rotatably mounted on the side of the guide screw block away from the drilling motor. The output end of the bore motor passes through the guide screw block and is connected to the drill rod; the stabilizing component includes a stabilizing sleeve, a spring-loaded seat, a limiting ring block, a powerful magnet, a stabilizing spring, and an anti-wear plate. The stabilizing sleeve is located on the upper wall of the guide seat at the end away from the guide motor. The spring-loaded seat is located on the side wall of the guide seat near the stabilizing sleeve and is located outside the threaded rod. The stabilizing spring passes through the stabilizing sleeve and is located on the side wall of the spring-loaded seat outside the drill rod. The limiting ring block is located on the side of the stabilizing spring away from the spring-loaded seat and is in contact with the side wall of the stabilizing sleeve. The powerful magnet is rotatably located on the inner wall of the limiting ring block outside the drill rod. The powerful magnet attracts the drill rod through magnetic force. The anti-wear plate is located on the side of the powerful magnet away from the limiting ring block.

[0011] In use, the output end of the guide motor drives the threaded rod to rotate, the rotation of the threaded rod causes the guide screw block to slide along the slide rail, the guide screw block causes the drill rod to extend out of the guide seat and fit against the position of the hole to be drilled on the wall, the output end of the drilling motor drives the drill rod to rotate, and as the guide motor continues to push the drill rod forward, the drill rod drills into the interior of the wall. When the drill rod extends out of the guide seat, the strong magnetic block is attracted to the outside of the drill rod. The elastic deformation of the stabilizing spring moves synchronously with the drill rod. The longer the drill rod extends, the greater the deformation of the stabilizing spring. The stretched stabilizing spring limits the longer drill rod extending out of the guide seat. The stabilizing spring uses its rebound force to pull the drill rod in the opposite direction under the attraction of the strong magnetic block, thereby keeping the drill rod and the output end of the drilling motor in a coaxial position, ensuring the drilling accuracy of the drill rod. As the drill rod penetrates deeper, it feeds into the wall and the abrasion plate. The abrasion plate then blocks the powerful magnetic block from continuing to move with the drill rod, keeping it in place. The drill rod penetrates into the wall, and the magnetic block's attraction point changes with the drill rod's feed. After drilling the first set of holes, the guide motor output drives the threaded rod to reverse, and the drill rod extends out of the hole. At this point, the distance between the drill rod tip and the side wall of the abrasion plate is the hole depth. This allows operators to easily measure the hole depth and also provides a depth basis for the next set of holes.

[0012] The lifting assembly includes a lifting boom and a hydraulic cylinder three. The lifting boom is hinged to the upper wall of the chassis at the end away from the steering platform, and the hydraulic cylinder three is hinged between the lifting boom and the upper wall of the chassis. The jacking assembly includes a second-section boom, a hydraulic cylinder four, a third-section boom, a hydraulic cylinder five, and a support frame. The second-section boom is slidably located at the end of the lifting boom away from the chassis. The hydraulic cylinder four is located between the bottom side wall of the lifting boom and the top side wall of the second-section boom. The third-section boom is slidably located at the end of the second-section boom away from the lifting boom. The hydraulic cylinder five is located between the top side wall of the second-section boom and the top side wall of the third-section boom. The support frame is located on the side of the third-section boom away from the second-section boom.

[0013] In use, the third output end of the hydraulic cylinder shortens and pulls the lifting boom, which rotates along the upper wall of the chassis and is lifted, changing the lifting boom from an inclined state to a vertical state. Then, the fourth and fifth output ends of the hydraulic cylinders extend respectively, the second section of the arm slides out along the lifting boom, and the third section of the arm slides out along the second section of the arm. The third section of the arm drives the support frame to fit against the top of the building or rock strata, providing support for it and providing a stable and safe working space for operators inside the tunnel or building.

[0014] Preferably, the upper wall of the chassis is provided with a control console.

[0015] Furthermore, the control console is electrically connected to the drive motor, hydraulic cylinder one, hydraulic cylinder two, rotary motor, guide motor, drilling motor, hydraulic cylinder three, hydraulic cylinder four, and hydraulic cylinder five, respectively.

[0016] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution combines a steering mechanism, a directional adjustment mechanism, a drilling mechanism, and a support mechanism. Through the setting of drive rotation components, drive arm components, lifting arm components, rotation components, drill extension components, drilling components, stabilization components, lifting components, and jacking components, and with the cooperation of the drive boom, drive arm, and guide seat, it can perform drilling operations at different heights of the building. Utilizing the deformation and resilience of the stabilizing spring, the drill rod is pulled back in the opposite direction under the magnetic attraction of the strong magnetic block, always keeping the drill rod and the output end of the drilling motor in a coaxial and horizontal state. This ensures the drilling stability of the drill rod with a long extension outside the guide seat, reduces the probability of drill bit swaying, and improves drilling accuracy.

[0026] The lifting assembly 35 includes a lifting boom 36 and a hydraulic cylinder 37.

The jacking assembly 38 includes a second-section boom 39, a fourth hydraulic cylinder 40, a third-section boom 41, a fifth hydraulic cylinder 42, and a support frame 43.

The fourth hydraulic cylinder 40 is disposed between the bottom side wall of the lifting boom 36 and the top side wall of the second-section boom 39. The third-section boom 41 is slidably disposed at the end of the second-section boom 39 away from the lifting boom 36. The fifth hydraulic cylinder 42 is disposed between the top side wall of the second-section boom 39 and the top side wall of the third-section boom 41. The support frame 43 is disposed on the side of the third-section boom 41 away from the second-section boom 39.

[0027] The upper wall of the chassis 1 is equipped with a control console 44.

[0028] The control console 44 is electrically connected to the drive motor 6, hydraulic cylinder 9, hydraulic cylinder 14, rotary motor 16, guide motor 21, drilling motor 26, hydraulic cylinder 37, hydraulic cylinder 40, and hydraulic cylinder 5 42, respectively.

[0029] In actual use, the operator controls the chassis 1 to move to the work area via the moving wheels 2, and the control console 44 controls the drive motor 6 to start. The output end of the drive motor 6 drives the steering table 5 to rotate, and the steering table 5 drives the drive boom 8 to rotate away from the chassis 1. At this time, an angle is generated between the relatively parallel drive booms 8. Then the control console 44 controls the hydraulic cylinder 9 to start, and the output end of the hydraulic cylinder 9 extends to drive the drive boom 8 to rotate and lift along the steering table 5 to adjust the drilling height. The control console 44 starts the hydraulic cylinder 37, and the output end of the hydraulic cylinder 37 shortens to pull the lifting boom 36. The lifting boom 36 rotates and lifts along the upper wall of the chassis 1, changing the lifting boom 36 from an inclined state to a vertical state. Then, the control console 44 controls the output ends of the hydraulic cylinders 40 and 42 to extend. The second section arm 39 slides out along the lifting boom 36, and the third section arm 41 slides out along the second section arm 39. The third section arm 41 drives the support frame 43 to fit against the top of the building or rock strata, providing support for it and providing a stable and safe working space for operators inside the tunnel or building. The control console 44 controls the hydraulic cylinder 2 14 to start. The output end of the hydraulic cylinder 2 14 extends to drive the drive arm 13. The drive arm 13 rotates along one end of the drive arm 8 to drive the guide seat 20 to adjust the drilling position. The control console 44 controls the guide motor 21 to start. The rotary motor 16 drives the turntable 17 to rotate through the output end. The turntable 17 drives the drill rod 27 to align with the drilling position through the guide seat 20. The control console 44 controls the start of the guide motor 21. The output of the guide motor 21 drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 causes the guide screw block 24 to slide along the slide rail 23. The guide screw block 24 causes the drill rod 27 to extend out of the guide seat 20 and fit into the position of the hole to be drilled on the wall. The control console 44 controls the start of the drilling motor 26. The output of the drilling motor 26 drives the drill rod 27 to rotate. As the guide motor 21 continues to push the drill rod 27, the drill rod 27 drills into the interior of the wall. When the drill rod 27 extends out of the guide seat 20, the strong magnetic block 32 is attracted to the outside of the drill rod 27. The elastic deformation of the stabilizing spring 33 follows the drill rod 27 synchronously. The longer the drill rod 27 extends, the greater the deformation of the stabilizing spring 33. The stretched stabilizing spring 33 limits the longer drill rod 27 extending out of the guide seat 20. The stabilizing spring 33 uses its rebound force to pull the drill rod 27 in the opposite direction under the attraction of the strong magnetic block 32. The drill rod 27 drives the strong magnetic block 32 to rotate along the inner wall of the limiting ring block 31, thereby keeping the drill rod 27 and the output end of the drilling motor 26 in a coaxial position, ensuring the drilling accuracy of the drill rod 27. As the drilling depth of drill rod 27 increases, the wall surface and the anti-wear plate 45 come into contact with each other as drill rod 27 feeds. The anti-wear plate 45 then blocks the strong magnetic block 32 from continuing to move with drill rod 27, keeping the strong magnetic block 32 in place. Drill rod 27 drills into the interior of the wall. The attraction point of the strong magnetic block 32 to drill rod 27 changes as drill rod 27 feeds. After drilling the first set of holes, the output end of guide motor 21 drives threaded rod 22 to reverse, and drill rod 27 extends out of the hole. At this time, the distance between the tip of drill rod 27 and the side wall of anti-wear plate 45 is the hole depth. This makes it easy for operators to measure the hole depth and also lays a foundation for the depth of the next set of new holes. The above operation can be repeated for the next use.

[0031] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
