DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1 to 5 As shown, this embodiment provides a drilling angle adjustment mechanism for a mining drill power head, including: a hydraulic turntable 1, a turntable 2 is fixedly connected to the hydraulic turntable 1, and two hydraulic lifting rods 3 are symmetrically fixedly connected to the turntable 2; the hydraulic lifting rod 3 includes a fixed column 301 and a movable sleeve 302, the movable sleeve 302 is slidably connected to the outside of the fixed column 301, the bottom of the fixed column 301 is fixedly connected to the turntable 2, a hydraulic telescopic rod 4 is hinged between the bottoms of the two movable sleeves 302, a mounting seat 5 is hinged at the top of the two movable sleeves 302, a power head assembly is slidably connected to the mounting seat 5, and one end of the bottom of the mounting seat 5 away from the hinge point with the movable sleeve 302 is hinged to the movable end of the hydraulic telescopic rod 4.

[0025] The hydraulic turntable 1 is fixed to the drilling rig, and the turntable 2 can be driven to rotate 360° on the horizontal plane through the hydraulic turntable 1 to adjust the horizontal angle; the hydraulic lifting rod 3 can drive the mounting seat 5 to rise and fall to adjust the height; the hydraulic telescopic rod 4 pushes the mounting seat 5 to rotate vertically with the hinge axis at the top of the movable sleeve 302 as the axis through telescoping to adjust the vertical angle. Multiple adjustment structures work together to adjust the drilling angle of the power head assembly on the mounting seat 5. The drilling angle can be adjusted without moving the drilling rig as a whole, which is more suitable for the narrow environment underground. At the same time, it is more convenient to operate, reduces manpower, and speeds up construction efficiency.

[0026] According to a further optimized solution, hinge plates 6 are extended outward from the tops of the two movable sleeves 302 , two hinge columns 7 are fixedly connected to both sides of the mounting seat 5 , and the two hinge columns 7 are correspondingly rotatably connected to the two hinge plates 6 .

[0027] After the hinged plate 6 extends a distance to one side of the movable sleeve 302, it is hinged to the mounting seat 5, so that the rotation axis of the mounting seat 5 when it rotates vertically is located outside the vertical projection of the hydraulic turntable 1. In this way, when the mounting seat 5 is set vertically to the ground, the hydraulic turntable 1 can be prevented from interfering with the downward drilling of the power head assembly.

[0028] A further optimized solution is that a cross bar 8 is fixed between the bottoms of the two movable sleeves 302 , the hydraulic telescopic rod 4 includes an outer tube 401 and a telescopic inner rod 402 , two connecting plates 9 are symmetrically fixed to the top of one end of the outer tube 401 close to the telescopic inner rod 402 , and the cross bar 8 passes through the two connecting plates 9 .

[0029] The hydraulic telescopic rod 4 is hinged by rotating the connecting plate 9 and the cross bar 8. Two connecting plates 9 are symmetrically arranged to ensure the left and right balance of the hydraulic telescopic rod 4; the outer cylinder 401 is fixedly connected to the connecting plate 9 on one side close to the telescopic inner rod 402, which can shorten the distance between the hydraulic telescopic rod 4 and the mounting seat 5 when the hydraulic telescopic rod 4 is contracted, thereby increasing the rotation range of the mounting seat 5.

[0030] A further optimized solution is that a sliding groove 10 is opened at the center of the front side of the mounting seat 5, and a screw rod 11 is rotatably connected in the sliding groove 10. One end of the screw rod 11 passes through the end surface of the mounting seat 5 and is fixedly connected to a sliding motor 12. The sliding motor 12 is fixed to the end of the mounting seat 5. A slider 13 is slidably connected in the sliding groove 10. The screw rod 11 and the slider 13 are threadedly connected. The top of the slider 13 extends out of the sliding groove 10 and is fixedly connected to the power head assembly.

[0031] The sliding motor 12 can rotate forward and backward, driving the screw 11 to rotate forward and backward, and then driving the slider 13 threadedly connected to the screw 11 to slide back and forth in the sliding groove 10, so that the power head assembly can move forward or backward along the axial direction of the mounting seat 5, thereby achieving the purpose of drilling or retreating the power head 15.

[0032] According to a further optimization scheme, the power head assembly includes a drilling motor 14 , the output end of the drilling motor 14 is transmission-connected to a power head 15 , and the power head 15 is transmission-connected to a drill rod 16 ; a motor seat 18 is fixedly connected to the bottom of the drilling motor 14 , and the slider 13 is fixedly connected to the motor seat 18 .

[0033] The drilling motor 14 drives the power head 15 to rotate, and the power head 15 drives the drill rod 16 to rotate, and cooperates with the sliding motor 12 to drive the drill rod 16 forward, so that the drill rod 16 drills axially along the mounting seat 5.

[0034] As a further optimization scheme, a clamping assembly 17 is fixedly connected to one end of the mounting seat 5 away from the drilling motor 14 . The clamping assembly 17 is sleeved on the outside of the drill rod 16 and is rotatably connected to the drill rod 16 .

[0035] The clamping assembly 17 clamps the drill rod 16 from both sides of the drill rod 16 and limits the position of the drill rod 16 to prevent the drill rod 16 from tilting. The structure of the clamping assembly 17 is a common structure of a drilling rig and is well known to those skilled in the art, so it will not be described in detail here.

[0036] According to a further optimized solution, guide grooves 19 are symmetrically provided on both sides of the bottom surface of the motor seat 18 , guide rails 20 are fixedly connected to both sides of the front surface of the mounting seat 5 , and the guide grooves 19 are slidably connected to the guide rails 20 .

[0037] A guide groove 19 is provided under the motor seat 18 and is slidably connected to the guide rail 20, which can reduce the friction when the slider 13 drives the power component to slide, and provide guidance for the sliding of the power component on the mounting seat 5 to avoid sliding deviation.

[0038] According to a further optimized solution, the hydraulic telescopic rod 4 is a multi-stage telescopic rod.

[0039] The multi-stage telescopic rod has a larger telescopic displacement, which can increase the vertical rotation range of the mounting seat 5.

[0040] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0041] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
