It is connected to a driving shaft 304, and one end of the driving shaft 304 away from the clamping shell 301 is fixedly connected to a rotating handle 302. The driving shaft 304 is symmetrically fixedly connected to two rotating slide columns 305 on the outer side surface inside the clamping shell 301. The inside of the clamping shell 301 is rotatably connected to a translation sleeve 306. Two special-shaped sliding grooves are provided on the side of the translation sleeve 306. The rotating slide column 305 is slidingly connected to the translation sleeve 306 through the special-shaped sliding groove. The sliding of the rotating slide column 305 in the special-shaped sliding groove can push the translation sleeve 306 to move forward. The outer side surface of the translation sleeve 306 is symmetrically fixedly connected to two connecting rods 307, one end of the connecting rod 307 is fixedly connected to a driven connecting rod 308, and both ends of the driven connecting rod 308 are symmetrically fixedly connected to sliding baffles 309.

[0037] like Figure 5As shown, a sliding groove is provided on one side of the clamping shell 301 close to the supporting slide rail 102, and a matching slider 310 is slidably connected in the sliding groove. The matching slider 310 is rotatably connected to a rotating slider 311 through a rotating shaft. The rotating slider 311 is slidably connected inside the arc-shaped sliding groove of the supporting slide rail 102. Right-angled triangular teeth are provided on the opposite inner side surfaces of the square sliding groove of the supporting slide rail 102. The triangular teeth are right-angled triangles and the upper side surfaces are right-angled sides.

[0038] like Figure 7-Figure 9 As shown, two support columns 101 are symmetrically fixedly connected to the other side of the upper side of the chassis 1, a rotating shaft column 106 is fixedly connected to the support column 101, a fixed block 107 is fixedly connected to the outer side of the rotating shaft column 106, a platform rotating shaft 108 is fixedly connected to the outer side of the fixed block 107, a drilling device 2 is provided on the outer side of the platform rotating shaft 108, the drilling device 2 includes a drilling platform 202, the drilling platform 202 is rotatably connected to the outer side of the platform rotating shaft 108, a sliding column 203 is slidably connected inside the arc-shaped slide groove of the support slide rail 102, and the sliding column 203 is symmetrically fixedly connected to both sides of the other end of the drilling platform 202.

[0039] like Figure 8 As shown, teeth are provided at both ends of the platform shaft 108 and at the outer side surfaces outside the drilling platform 202. Two slide rails are provided on both sides of the drilling platform 202 at the platform shaft 108. Angle limit devices 4 are provided on both sides of the drilling platform 202. The angle limit devices 4 include clamping slide blocks 403. The drilling platform 202 is slidably connected with the clamping slide blocks 403 through the slide rails. One end of the clamping slide block 403 is provided with teeth that match the teeth at both ends of the platform shaft 108. The platform shaft 108 can be quickly clamped through the cooperation of the teeth, so that the drilling rig The platform 202 no longer rotates around the platform rotation axis 108. The outer side surface of the clamping slider 403 is fixedly connected to the matching connecting rod 402. A threaded hole is opened at one end of the matching connecting rod 402. The matching connecting rod 402 is matched with the threaded rod 405 through the threaded hole. The threads on the outer side of the threaded rod 405 are in opposite directions. Rotation in a single direction can cause the matching connecting rods 402 on both sides to move toward the middle of the threaded rod 405. The outer side of the threaded rod 405 is rotatably connected to a threaded protective sleeve 404, and one end of the threaded rod 405 is fixedly connected to a threaded handle 401.

[0040] like Fig. 9 As shown, slide rails are provided on both sides of the upper side of the drilling platform 202, and the drilling platform 202 is slidably connected to the directional drilling rig 201 via the slide rails.

[0041] like Figure 2As shown, the upper side of the chassis 1 is fixedly connected with a hydraulic telescopic rod 103, and the upper side of the hydraulic telescopic rod 103 is symmetrically fixedly connected with a rotating shaft plate 104, and the rotating shaft plate 104 is rotatably connected with a support block 105 through a rotating shaft, and the support block 105 is fixedly connected to the lower side of the drilling rig platform 202. The support block 105 supports the drilling rig platform 202 to move to the corresponding position as the hydraulic telescopic rod 103 is lifted. When the drilling rig platform 202 rotates around the platform rotating shaft 108, the support block 105 will rotate around the rotating shaft on the rotating shaft plate 104, thereby better supporting the rotation of the drilling rig platform 202.

[0042] Example 2: Before the drilling rig starts working, angle adjustment is required. At this time, the hydraulic telescopic rod 103 is started, and one end of the drilling rig platform 202 is controlled to rise and fall by extending and retracting the hydraulic telescopic rod 103 in the up and down directions. At this time, the drilling rig platform 202 rotates around the platform rotating shaft 108, and the adjustment angle is determined according to the scale line on the supporting slide rail 102.

[0043] After adjusting to the required angle, move the auxiliary support device 3. At this time, the connecting slider 312 moves in the square slide groove of the support slide rail 102, and the rotating slider 311 slides in the arc-shaped slide groove. At the same time, it will drive the matching slider 310 to translate left and right in the slide groove on the inner side of the clamping shell 301, so that the entire auxiliary support device 3 can translate on the support slide rail 102.

[0044] When the auxiliary support device 3 runs to the required position, the handle 302 is twisted to drive the active shaft 304 to rotate. At this time, the rotating slide column 305 on the active shaft 304 rotates around the active shaft 304, and the rotating slide column 305 slides in the special-shaped slide groove on the translation sleeve 306. Due to the special shape of the slide groove, the translation sleeve 306 is driven to move outward inside the clamping shell 301, thereby driving the connecting rod 307 to move, and the sliding baffle 309 is driven by the driven connecting rod 308 to move along the corresponding slide groove inside the clamping shell 301 toward the inside of the support slide rail 102.

[0045] At this time, when the sliding baffle 309 moves to the upper part of the triangular teeth inside the square slide groove 102, the sliding baffle 309 cooperates with the triangular teeth inside the square slide groove of the supporting slide rail 102, so that the entire auxiliary support device 3 is locked on the outer side of the supporting slide rail 102, and the two rotating sliders 311 lock the sliding columns 203 on both sides of one end of the drilling rig platform 202, so that the drilling rig platform 202 stays in a determined position.

[0046] In addition, when the drilling rig platform 202 is rotated to the required angle and the auxiliary support device 3 has been fixed, the threaded handle 401 is rotated to drive the threaded rod 405 to rotate. At this time, the matching connecting rods 402 at both ends of the threaded rod 405 are displaced toward the middle of the threaded rod 405 through threaded matching, thereby driving the clamping slider 403 to displace toward the platform shaft 108, and the angle is limited by the mutual engagement between the teeth of the clamping slider 403 and the platform shaft 108.

[0047] When the directional drilling rig 201 has completed its work and needs to reset the angle, the threaded handle 401 can be rotated in the opposite direction to release the angle limit, and the rotating handle 302 can be twisted in the opposite direction to drive the entire mechanism to move in the opposite direction, thereby releasing the locking function of the auxiliary support device 3 and starting the hydraulic telescopic rod 103 to adjust the drilling rig platform 202 to the horizontal direction, thereby achieving the angle reset adjustment of the drilling rig platform 202.

[0048] Embodiment 3: A method for adjusting the angle of a mining directional drill 201, comprising the following steps:

[0049] S1, start the motor, through the hydraulic telescopic rod 103 in the up and down direction of telescoping, control the lifting of one end of the drilling platform 202, according to the support rail 102 on the scale line to determine the size of the adjustment angle;

[0050] S2, the connecting slider 312 moves in the square slot of the supporting slide rail 102, and the rotating slider 311 slides in the arc slot, which drives the matching slider 310 to translate left and right in the slot on the inner side of the clamping shell 301, so that the entire auxiliary support device 3 translates on the supporting slide rail 102;

[0051] S3, twist the rotating handle 302 to drive the driving shaft 304 to rotate, and the rotating slide column 305 slides in the slide groove on the translation sleeve 306, driving the translation sleeve 306 to move inside the clamping housing 301, thereby driving the connecting rod 307 to move, and driving the sliding baffle 309 to move through the driven connecting rod 308;

[0052] S4, the sliding baffle 309 cooperates with the triangular teeth inside the square slide groove of the support rail 102, so that the entire auxiliary support device 3 is locked on the outer side of the support rail 102;

[0053] S5, the threaded handle 401 is rotated to drive the threaded rod 405 to rotate, and the matching connecting rods 402 at both ends of the threaded rod 405 are displaced toward the middle of the threaded rod 405 through thread matching, thereby driving the clamping slider 403 to displace toward the platform shaft 108, and the angle is limited by the mutual engagement between the teeth of the clamping slider 403 and the platform shaft 108;

[0054] S6, when the angle needs to be reset, the threaded handle 401 can be rotated in the reverse direction to release the angle limit, and the rotating handle 302 can be twisted in the reverse direction to drive the entire mechanism to move in the reverse direction to release the locking function of the auxiliary support device 3.

[0055] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
