Description

Technical Field

[0001] The invention relates to the technical field of tunnel drilling, and in particular to a tunnel drilling device capable of fixing an angle. Background Art

[0002] The air-leg anchor drill is a kind of equipment widely used in mine tunnel support, tunnel engineering and other underground construction fields. It uses compressed air as a power source to drive the drill to perform drilling operations.

[0003] Some air-leg anchor drilling rigs usually have the following characteristics: 1. Flexibility: Due to the telescopic function of the air leg, the existing air-leg 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 complicated cable laying, which is suitable for frequently moving working environments; 3. Simple operation: Compared with electric or hydraulic systems, the pneumatic system is relatively simple to operate and maintain, which reduces the operating threshold for workers. However, although the air leg can adapt to a certain range of height adjustment, its support stability may be insufficient for extremely uneven working surfaces or those that require precise angle control, and in operations that require precise drilling angles and depths, the adjustment range and accuracy of the existing air leg may not be sufficient to meet high standards. Within the scope of application, for specific complex geological conditions or drilling requirements at special angles, the adaptability and flexibility of traditional air-leg drilling rigs are limited.

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

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims. The terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, product or device including a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, product or device. In the absence of more restrictions, it is not excluded that there are other identical or equivalent elements in the process, method, product or device including the elements. For example, if the words first, second, etc. are used to represent the name, they do not represent any specific order.

[0027] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element.

At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0031] A tunnel drilling device capable of fixing an angle, such as Figure 1-Figure 9 As shown, it includes an installation base frame 1, an air-leg anchor drill 2, a fixing component 3 and a supporting mechanism 4. The upper part of the installation base frame 1 is provided with a fixing component 3, and the air-leg anchor drill 2 is installed on the fixing component 3. The fixing component 3 is used to fix air-leg anchor drills 2 of different models. The fixing component 3 is provided with a supporting mechanism 4 for adjusting the angle of the air-leg anchor drill 2.

[0032] The fixing assembly 3 includes a fixing frame 30, a telescopic frame 31, a first mounting frame 32, a locking piece 33 and a fastener 34. The fixing frame 30 is rotatably connected to the upper part of the mounting chassis frame 1. The telescopic frame 31 is connected to the fixing frame 30. The telescopic frame 31 is a multi-stage telescopic structure. The telescopic end of the telescopic frame 31 is connected to the first mounting frame 32. A locking piece 33 is provided on the side of the first mounting frame 32 close to the air-leg anchor drilling rig 2. The left and right ends of the locking piece 33 are symmetrically rotatably connected to the fasteners 34. The fasteners 34 are both threadedly connected to the first mounting frame 32. The air-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, so as to adapt to different types of air-leg anchor drill 2. The air-leg anchor drill 2 is installed and fixed by the locking member 33 and the fastener 34, so that the rotation of the fixing frame 30 and the lifting and lowering movement of the telescopic frame 31 can act on the air-leg anchor drill 2, thereby assisting the air-leg anchor drill 2 to perform telescopic and rotating movements, thereby improving the controllability of the air-leg anchor drill 2;

[0033] The support mechanism 4 includes a rotating member 40, a screw rod 41, a rotating handle 42, a telescopic rod 43, a telescopic sleeve 44 and a support seat 45. The first mounting frame 32 is rotatably connected to the rotating member 40 on the side away from the air leg anchor drill 2. The bottom of the rotating member 40 is rotatably connected to the screw rod 41. The upper part of the screw rod 41 is connected to the rotating handle 42. The lower end of the rotating member 40 is symmetrically connected to the screw rod 41 on both sides. The telescopic rod 43 is slidably connected to the telescopic sleeve 44. The bottom of the telescopic sleeve 44 is connected to the support seat 45, the support seat 45 is threadedly connected with the screw rod 41, and the screw rod 41 is rotated by rotating the handle 42. The screw rod 41 rotates to cooperate with the telescopic rod 43 and the sleeve to control the lifting movement of the support seat 45, and the position of the support seat 45 is changed. By changing the position of the support seat 45, the center of gravity of the telescopic frame 31 is changed to adapt the rotation angle of the fixed frame 30, and at a specific angle, the support seat 45 supports the telescopic frame 31, which saves the manpower required for the angle adjustment of the air leg type anchor drilling rig 2 and improves the stability of the air leg type anchor drilling rig 2 when used at a specific angle;

[0034] The locking mechanism 5 is also included. The locking mechanism 5 includes a second mounting frame 50, a lifting handle 51, a locking pile 52, a spring 53 and a connecting piece 54. Both ends of the mounting chassis frame 1 away from the fixing frame 30 are connected to the connecting pieces 54. The second mounting frame 50 is slidably connected to the connecting pieces 54. The lower end of the second mounting frame 50 is connected to the lifting handle 51. The upper end of the second mounting frame 50 is connected to a locking pile 52 near the mounting chassis frame 1. The locking pile 52 passes through the mounting chassis frame and is inserted into the fixing frame 30 to lock. A spring 53 is connected between the pile 52 and the mounting chassis frame 1. Before the fixing frame 30 rotates, the second mounting frame 50 needs to be controlled to move away from the mounting chassis frame 1 by pulling the handle 51, so that after the locking pile 52 is separated from the fixing frame 30, the fixing frame 30 can rotate normally. When the locking pile 52 is separated from the fixing frame 30, the spring 53 is stretched. After the fixing frame 30 rotates, the lifting handle 51 is released, the spring 53 rebounds, and the locking pile 52 on the second mounting frame 50 is reinserted into the fixing frame 30 to lock the fixing frame 30.

[0035] It also includes a stabilizing mechanism 6, which includes a mounting seat 60, a connecting rod 61, a mounting block 62 and a rotating support foot 63. The mounting seat 60 is symmetrically connected to the lower part of the mounting chassis frame 1, and the mounting seat 60 is connected to the connecting rod 61. The front and rear ends of the connecting rod 61 are connected to the mounting blocks 62, and the mounting blocks 62 are threadedly connected to the rotating support feet 63. Rotating the rotating support feet 63 can control the rotating support feet 63 to be at different heights to adapt to different terrains in the use scenario, thereby improving the supporting stability of the mounting chassis frame 1.

[0036] When the present invention is in use, the device is first set in the tunnel drilling area. 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 use scenario and improve the support stability of the installation base frame 1. Then, the air-leg anchor drill 2 is installed and fixed between the first mounting frame 32 and the locking member 33. The bottom of the air-leg anchor drill 2 is supported by the fixing frame 30. The air-leg anchor drill 2 is installed and fixed by the locking member 33 and the fastener 34, so that the rotation of the fixing frame 30 and the lifting and lowering movement of the telescopic frame 31 can act on the air-leg anchor drill 2, thereby assisting the air-leg anchor drill 2 to perform telescopic and rotating movements, thereby improving the controllability of the air-leg anchor drill 2. When the fixing frame 30 drives the air-leg anchor drill 2 to change its angle, the screw rod 41 is rotated by the rotating handle 42. The screw rod 41 rotates to cooperate with the telescopic rod 43 and the sleeve to control the lifting and lowering movement of the support seat 45, thereby changing the support seat 45 position, by changing the position of the support seat 45, the center of gravity of the telescopic frame 31 is changed to adapt the rotation angle of the fixed frame 30, and the support seat 45 supports the telescopic frame 31 at a specific angle, saving the manpower required for angle adjustment of the air-leg type anchor drilling rig 2, and improving the stability of the air-leg type anchor drilling rig 2 when used at a specific angle. Before the fixed frame 30 rotates, it is necessary to control the second mounting frame 50 to be away from the mounting base frame 1 by pulling the handle 51, so that after the locking pile 52 is separated from the fixed frame 30, the fixed frame 30 can rotate normally, and the spring 53 is stretched when the locking pile 52 is separated from the fixed frame 30. After the rotation of the fixed frame 30 is completed, the pulling handle 51 is released, the spring 53 rebounds, and the locking pile 52 on the second mounting frame 50 is reinserted into the fixed frame 30, so that the fixed frame 30 is locked, lifted and rotated, and the drill head direction of the air-leg type anchor drilling rig 2 is controlled to face the drilling position, and then the air-leg type anchor drilling rig 2 can be controlled to perform drilling operations.

[0037] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
