Description

Technical Field

[0001] This invention relates to the field of tunnel drilling technology, and more particularly to a tunnel drilling device that can adapt to different angles. Background Technology

[0002] Pneumatic-powered anchor drilling rigs are widely used in mine roadway support, tunnel engineering, and other underground construction fields. They utilize compressed air as a power source to drive the drilling rig for drilling operations.

[0003] Some pneumatic leg-type anchor drilling rigs typically possess the following characteristics: 1. Flexibility: Due to the telescopic function of the air leg, existing pneumatic leg-type drilling rigs can adapt to different heights and uneven working surfaces, providing basic support stability; 2. Portability: Pneumatic equipment is easy to carry and does not require complex cable laying, making it suitable for frequently moving working environments; 3. Simple operation: Compared to electric or hydraulic systems, pneumatic systems are relatively simple to operate and maintain, lowering the barrier to entry for workers. However, although the air leg can adapt to a certain range of height adjustments, its support stability may be insufficient for extremely uneven working surfaces or those requiring precise angle control. Furthermore, in operations requiring precise drilling angles and depths, the adjustment range and accuracy of existing air legs may not meet high standards. Within their applicable scope, for specific complex geological conditions or drilling requirements with special angles, the adaptability and flexibility of traditional pneumatic leg-type drilling rigs are limited.

[0004] Therefore, a tunnel drilling device that can adapt to different angles has been developed, which can adjust the working height and drilling angle to the maximum extent under inclined or complex geological conditions, significantly improving the accuracy of drilling and the stability of the operation. Summary of the Invention

[0005] In order to overcome the shortcomings of existing pneumatic leg anchor drilling rigs mentioned above, the present invention provides a tunnel drilling device that can adjust the working height and drilling angle to the maximum extent under inclined or complex geological conditions, thereby significantly improving the accuracy of drilling and the stability of operation.

[0006] The technical solution is: a tunnel drilling device that can adapt to different angles, including a mounting frame, a pneumatic leg anchor drill and a fixing component. The fixing component is provided on the upper part of the mounting frame, and the pneumatic leg anchor drill is installed on the fixing component.

[0007] Furthermore, the fixing components include a fixed frame, a telescopic frame, a first mounting frame, a locking element, and fasteners. The fixed frame is rotatably connected to the upper part of the mounting base frame, and the telescopic frame is connected to the fixed frame. The telescopic frame is a multi-segment telescopic structure, and the first mounting frame is connected to the telescopic end of the telescopic frame. The first mounting frame is provided with a locking element on the side of the first mounting frame near the pneumatic leg anchor drilling rig. Fasteners are symmetrically rotatably connected to the left and right ends of the locking element, and the fasteners are all threaded to the first mounting frame. The pneumatic leg anchor drilling rig is installed between the locking element and the first mounting frame. The distance between the locking element and the first mounting frame can be adjusted by rotating the fasteners to adapt to different models of pneumatic leg anchor drilling rigs.

[0008] Furthermore, the support mechanism includes a rotating component, a lead screw, a rotary handle, a telescopic rod, a telescopic sleeve, and a support base. The rotating component is rotatably connected to the side of the first mounting frame away from the pneumatic leg anchor drill. The lead screw is rotatably connected to the bottom of the rotating component. The rotary handle is connected to the upper part of the lead screw. Telescopic rods are symmetrically connected to both sides of the lower end of the rotating component with the lead screw as the center. Telescopic sleeves are slidably connected to the telescopic rods. A support base is connected between the bottoms of the telescopic sleeves. The support base is threadedly connected to the lead screw.

[0009] Furthermore, it also includes a locking mechanism, which includes a second mounting bracket, a lifting handle, a locking post, a spring, and a connector. The two ends of the mounting base away from the fixed frame are connected to connectors, and the second mounting bracket is slidably connected to each connector. The lower end of the second mounting bracket is connected to a lifting handle, and the upper end of the second mounting bracket is connected to a locking post on the side near the mounting base. The locking post passes through the mounting base and inserts into the fixed frame, and a spring connects the locking post to the mounting base.

[0010] Furthermore, it also includes a stabilizing mechanism, which includes a mounting base, connecting rods, mounting blocks, and rotating support feet. The mounting base is symmetrically connected to the lower part of the mounting frame, and each mounting base is connected to a connecting rod. Both ends of the connecting rods are connected to mounting blocks, and each mounting block is threadedly connected to a rotating support foot.

[0011] Furthermore, each of the rotating support feet is equipped with a rotating handle at the top.

[0012] Beneficial effects: 1. This invention supports the pneumatic leg anchor drilling machine with a fixed frame and controls the lifting operation of the pneumatic leg anchor drilling machine with a lifting frame. The fixed frame rotates to adapt to the angle adjustment requirements of the pneumatic leg anchor drilling machine. Under inclined or complex geological conditions, the working height and drilling angle can be adjusted to the maximum extent, which significantly improves the drilling accuracy and operation stability.

[0013] 2. This invention can control the rotating support foot to be at different heights by rotating it, so as to adapt to different terrains in the application scenario, improve the stability of the installation platform support, and adapt to more diverse geological environments and operation requirements. Whether drilling horizontally, inclined or vertically, it can achieve efficient and stable operation. Attached Figure Description

[0024] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0025] A tunnel drilling device that can adapt to different angles, such as Figures 1-9 As shown, it includes a mounting frame 1, a pneumatic leg anchor drill 2, and a fixing component 3. The mounting frame 1 is equipped with the fixing component 3 on its upper part, and the pneumatic leg anchor drill 2 is mounted on the fixing component 3. The fixing component 3 includes a fixing frame 30, a telescopic frame 31, a first mounting frame 32, a locking element 33, and fasteners 34. The fixing frame 30 is rotatably connected to the upper part of the mounting base frame 1. The telescopic frame 31 is connected to the fixing frame 30. The telescopic frame 31 is a multi-segment telescopic structure. The first mounting frame 32 is connected to the telescopic end of the telescopic frame 31. The locking element 33 is provided on the side of the first mounting frame 32 near the pneumatic leg anchor drilling rig 2. Fasteners 34 are symmetrically rotatably connected to the left and right ends of the locking element 33. All fasteners 34 are threadedly connected to the first mounting frame 32. The pneumatic leg anchor drill 2 is installed between the locking member 33 and the first mounting frame 32. The distance between the locking member 33 and the first mounting frame 32 can be adjusted by rotating the fastener 34 to adapt to different models of pneumatic leg anchor drill 2. The pneumatic leg anchor drill 2 is installed and fixed by the locking member 33 and the fastener 34, so that the rotation of the fixed frame 30 and the lifting and lowering movement of the telescopic frame 31 can act on the pneumatic leg anchor drill 2, thereby assisting the pneumatic leg anchor drill 2 in telescopic and rotational movements and improving the operability of the pneumatic leg anchor drill 2. The support mechanism 4 includes a rotating component 40, a lead screw 41, a rotating handle 42, a telescopic rod 43, a telescopic sleeve 44, and a support base 45. The rotating component 40 is rotatably connected to the side of the first mounting frame 32 away from the pneumatic anchor drill 2. The lead screw 41 is rotatably connected to the bottom of the rotating component 40. The rotating handle 42 is connected to the upper part of the lead screw 41. Telescopic rods 43 are symmetrically connected to both sides of the lower end of the rotating component 40, centered on the lead screw 41. Telescopic sleeves 44 are slidably connected to each telescopic rod 43. A support base is connected between the bottoms of the telescopic sleeves 44. 45. The support base 45 is threadedly connected to the lead screw 41. The lead screw 41 is rotated by the rotating handle 42. The rotation of the lead screw 41, in conjunction with the telescopic rod 43 and the sleeve, controls the lifting and lowering movement of the support base 45, changing the position of the support base 45. By changing the position of the support base 45, the center of gravity of the telescopic frame 31 is changed, adapting to the rotation angle of the fixed frame 30. At a specific angle, the support base 45 supports the telescopic frame 31, saving the manpower required for angle adjustment of the pneumatic leg anchor drilling machine 2 and improving the stability of the pneumatic leg anchor drilling machine 2 at a specific angle. It also includes a locking mechanism 5, which comprises a second mounting bracket 50, a lifting handle 51, a locking post 52, a spring 53, and a connector 54. Connectors 54 are connected to both ends of the mounting base 1 away from the fixed frame 30. The second mounting bracket 50 is slidably connected to each connector 54. A lifting handle 51 is connected to the lower end of each second mounting bracket 50. A locking post 52 is connected to the upper end of the second mounting bracket 50 near the mounting base 1. The locking post 52 passes through the mounting base and inserts into the fixed frame 30, locking the mounting. A spring 53 connects the stake 52 to the mounting frame 1. Before the fixed frame 30 rotates, the second mounting frame 50 needs to be moved away from the mounting frame 1 by pulling the handle 51 so that the fixed frame 30 can rotate normally after the locking stake 52 is disengaged from the fixed frame 30. When the locking stake 52 is disengaged from the fixed frame 30, the spring 53 is stretched. After the fixed frame 30 has rotated, the handle 51 is released, the spring 53 rebounds, and the locking stake 52 on the second mounting frame 50 is reinserted into the fixed frame 30 to lock the fixed frame 30. It also includes a stabilizing mechanism 6, which includes a mounting base 60, a connecting rod 61, a mounting block 62, and a rotating support foot 63. The mounting base 1 is symmetrically connected to the lower left and right sides of the mounting base 60. Each mounting base 60 is connected to a connecting rod 61. Both ends of the connecting rod 61 are connected to mounting blocks 62. Each mounting block 62 is threadedly connected to a rotating support foot 63. Rotating the rotating support foot 63 can control the rotating support foot 63 to be at different heights to adapt to different terrains in the usage scenario and improve the support stability of the mounting base 1.

[0026] In use, the device is first set up in the tunnel drilling area. Rotating the rotating support foot 63 allows it to be positioned at different heights to adapt to different terrains and improve the stability of the mounting frame 1. Then, the pneumatic leg anchor drill 2 is installed and fixed between the first mounting frame 32 and the locking member 33. The bottom of the pneumatic leg anchor drill 2 is supported by the fixed frame 30. The locking member 33 and fasteners 34 secure the pneumatic leg anchor drill 2, allowing the rotation of the fixed frame 30 and the lifting and lowering of the telescopic frame 31 to act on the pneumatic leg anchor drill 2, thus assisting in its telescopic and rotational movements and improving its maneuverability. When the fixed frame 30 drives the pneumatic leg anchor drill 2 to change angles, the rotating handle 42 rotates the lead screw 41. The rotation of the lead screw 41, in conjunction with the telescopic rod 43 and the sleeve, controls the lifting and lowering of the support seat 45, changing the position of the support seat. At position 45, by changing the position of the support base 45, the center of gravity of the telescopic frame 31 is changed, which adapts to the rotation angle of the fixed frame 30. At a specific angle, the support base 45 supports the telescopic frame 31, saving the manpower required for angle adjustment of the pneumatic anchor drill 2 and improving the stability of the pneumatic anchor drill 2 at a specific angle. Before the fixed frame 30 rotates, the second mounting frame 50 needs to be moved away from the mounting base frame 1 by pulling the handle 51, so that after the locking stake 52 is disengaged from the fixed frame 30, the fixed frame 30 can rotate normally. When the locking stake 52 is disengaged from the fixed frame 30, the spring 53 is stretched. After the fixed frame 30 has rotated, the handle 51 is released, the spring 53 rebounds, and the locking stake 52 on the second mounting frame 50 is reinserted into the fixed frame 30 to lock the fixed frame 30. After raising, lowering and rotating, the drill bit of the pneumatic anchor drill 2 is controlled to face the drilling position, and the pneumatic anchor drill 2 can be operated to perform drilling operations.
