[0023] This utility model provides an adjustable anchor drilling device for slope reinforcement, such as... Figure 1-5As shown, the adjustable anchor drilling device for slope reinforcement includes: a support frame 1; a threaded rod 2 rotatably mounted on the support frame 1; an adjusting block 3 threaded onto the threaded rod 2, with a mounting frame 4 fixed on the adjusting block 3; a connecting shaft 5 rotatably mounted on the mounting frame 4, with a drill rod 7 detachably mounted on the connecting shaft 5 for drilling; a second motor 13 fixed on the mounting frame 4 for driving the connecting shaft 5 to rotate, the output shaft of the second motor 13 being connected to the connecting shaft 5 via a first coupling; and a power structure mounted on the support frame 1 for driving the threaded rod 2 to rotate to adjust the drilling depth.

[0024] In this embodiment, by setting a threaded rod 2 rotatably mounted on the support frame 1 and an adjusting block 3 threaded around it, the drilling depth can be adjusted by rotating the threaded rod 2 to drive the adjusting block 3 to move up and down. By setting a connecting shaft 5 rotatably mounted on the mounting frame 4, and detachably mounting the drill rod 7 on the connecting shaft 5, the connecting shaft 5 is driven to rotate by the second motor 13 (Siemens 1FT7 servo motor), which provides power for drilling. At the same time, since the mounting frame 4 and the adjusting block 3 are fixed, when it is necessary to adjust the drilling direction, the entire support frame 1 can be rotated, so that the connecting shaft 5 and the drill rod 7 can be adjusted to a suitable drilling direction according to the slope inclination angle, thus improving the flexibility of the drilling device.

[0025] In a further preferred embodiment of the present invention, the power structure includes a housing 14 fixed on the support frame 1, a first motor 15 installed in the housing 14, a rotating shaft 16 rotatably installed on the support frame 1 and connected to the output shaft of the first motor 15 via a second coupling, and gears 17 fixed on the rotating shaft 16 and the threaded rod 2 respectively and meshing with each other for transmission.

[0026] In this embodiment, the housing 14 fixed on the support frame 1 protects the internal first motor 15 from external interference or damage. By installing the first motor 15 inside the housing 14 and using a second coupling to connect the output shaft of the first motor 15 (NEMA 23) to the rotating shaft 16 rotatably mounted on the support frame 1, the first motor 15 can drive the rotating shaft 16 to rotate. Then, through the gears 17 fixed on the rotating shaft 16 and the threaded rod 2 respectively and meshing with each other, the rotational motion of the rotating shaft 16 is transmitted to the threaded rod 2, so that the threaded rod 2 can rotate accordingly, thereby driving the adjusting block 3 to move, and finally realizing the adjustment of the drilling depth.

[0027] In a further preferred embodiment of the present invention, a limiting cylinder 8 is fixed on the support frame 1. The limiting cylinder 8 is movably sleeved outside the drill rod 7 to stabilize the drill rod 7. A connecting frame 18 is installed on the side of the support frame 1 away from the drill rod 7. The connecting frame 18 can contact the ground to support the equipment.

[0028] In this embodiment, by fixing the limiting cylinder 8 on the support frame 1 and movably sleeved it on the outside of the drill rod 7, the drill rod 7 is stabilized, which can effectively reduce the deviation caused by the shaking of the drill rod 7 during drilling. By installing the connecting frame 18 on the side of the support frame 1 away from the drill rod 7, the connecting frame 18 can contact the ground, thereby providing an additional support point for the entire equipment, enhancing the stability of the equipment during operation, preventing safety accidents such as tipping over due to uneven force, and ensuring construction safety.

[0029] In a further preferred embodiment of the present invention, a limiting frame 9 is fixed on the mounting frame 4, a slider 10 is installed on the limiting frame 9, and a sliding groove 12 is provided on the support frame 1. The slider 10 is slidably installed in the sliding groove 12, and the slider 10 cooperates with the sliding groove 12 to limit the movement path of the limiting frame 9.

[0030] In this embodiment, by fixing the limiting frame 9 on the mounting frame 4 and installing the slider 10 on the limiting frame 9, and setting the slide groove 12 on the support frame 1, the slider 10 is slidably installed in the slide groove 12, which serves to limit the movement path of the limiting frame 9. This allows the mounting frame 4 to move stably along a predetermined trajectory when adjusting the drilling direction or position, effectively preventing the mounting frame 4 from deviating or shaking during movement and improving the accuracy of drilling operations.

[0031] In a further preferred embodiment of the present invention, a hydraulic rod 19 and a connecting rod 20 are hinged to the bottom of the support frame 1. A base 21 is hinged to the output rod of the hydraulic rod 19. The base 21 is fixedly connected to the connecting rod 20. The base 21 is provided with a moving wheel 22 for assisting the movement of the equipment.

[0032] In this embodiment, by hinged hydraulic rod 19 (EMG electric hydraulic actuator) and connecting rod 20 at the bottom of support frame 1, and hinged output rod of hydraulic rod 19 to base 21, while fixing base 21 to connecting rod 20, the height and angle of support frame 1 can be flexibly adjusted. The equipment status can be adjusted according to different slope conditions, improving applicability. By setting moving wheels 22 on base 21, the equipment can be easily moved when it needs to be moved, without the need for a lot of manpower to carry it, which greatly improves the mobility and ease of use of the equipment, and reduces construction preparation time and labor intensity.

[0033] In a further preferred embodiment of this utility model, flanges 6 are installed on the sides of the connecting shaft 5 and the drill rod 7 that are close to each other. The two flanges 6 are connected by fixing bolts, and rubber gaskets are provided on the sides of the two flanges 6 that are close to each other.

[0034] In this embodiment, by installing flanges 6 on the sides of the connecting shaft 5 and the drill rod 7 that are close to each other, and connecting the two flanges 6 with fixing bolts, the drill rod 7 can be quickly disassembled and assembled. When the drill rod 7 is worn or needs to be replaced with a different specification, the operation can be easily completed, improving the maintenance efficiency and flexibility of the equipment. At the same time, rubber pads are set on the sides of the two flanges 6 that are close to each other, which plays a role in buffering and shock absorption, effectively reducing the impact force caused by vibration during the rotation of the connecting shaft 5 and the drill rod 7, reducing the risk of component damage, and extending the service life of the equipment.

[0035] In a further preferred embodiment of the present invention, the second motor 13 is covered with a protective shell for protecting the second motor 13, and both the shell 14 and the protective shell are provided with heat dissipation mesh for assisting the motor to dissipate heat. A connecting cylinder is provided between the connecting frame 18 and the support frame 1.

[0036] In this embodiment, by covering the second motor 13 with a protective shell, the second motor 13 is protected, effectively preventing damage to the second motor 13 from external dust, debris, and collisions, thus extending its service life. The heat dissipation mesh on the housing 14 and the protective shell assists in heat dissipation of the motor, allowing the heat generated during motor operation to be dissipated in a timely manner, preventing performance degradation or damage due to overheating, and ensuring stable operation of the motor. By setting a connecting cylinder between the connecting frame 18 and the support frame 1, the stability of the connection between the connecting frame 18 and the support frame 1 is enhanced, making the overall structure of the equipment more stable and reliable.

[0037] In a further preferred embodiment of this utility model, a cylinder for adjusting the height of the equipment after it is laid horizontally is installed inside the connecting cylinder. The output rod of the cylinder is connected to the support frame 1. A ball bearing 11 is embedded on the slider 10 to reduce friction by contacting the inner wall of the slide groove 12.

[0038] In this embodiment, by installing a cylinder (SC-DR50X75 standard cylinder) inside the connecting cylinder and connecting the cylinder output rod to the support frame 1, the height of the equipment can be flexibly adjusted after being placed horizontally. When facing different terrains or construction needs, the height of the support frame 1 can be quickly adjusted, improving the adaptability of the equipment to complex environments. By embedding ball bearings 11 on the slider 10 that contact the inner wall of the slide groove 12, the friction is reduced. When the mounting frame 4 moves and drives the slider 10 to slide in the slide groove 12, the ball bearings 11 can reduce the friction between the two, making the sliding process smoother, reducing energy loss, reducing component wear, and extending the service life of the equipment.

[0039] In summary, compared with related technologies, this device can adjust the drilling depth by setting a threaded rod 2 rotatably mounted on the support frame 1 and an adjusting block 3 threadedly sleeved on the outside of it. It can provide power for drilling by rotating the connecting shaft 5 mounted on the mounting frame 4 in conjunction with the detachable drill rod 7 and the second motor 13, and can adjust the drilling direction according to the slope inclination angle.
