DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0023] like Figure 1-3 As shown, this embodiment provides a fully mechanized mining face discharge hole drilling rig, comprising a sliding track 100, a sliding bracket 200, an adjustment component and a drilling rig body;

[0024] The sliding bracket 200 is slidably arranged on the sliding rail 100, and a walking mechanism and a locking mechanism are also arranged between the sliding bracket 200 and the sliding rail 100; the drilling rig body is installed on the sliding bracket 200, and a drilling rig platform 600 for fixing the drilling rig body is arranged on the sliding bracket 200, and the adjustment component is arranged between the drilling rig platform 600 and the sliding bracket 200, and the adjustment component includes a telescopic cylinder 410 and a lifting mechanism, one end of the telescopic cylinder 410 is hinged to the sliding bracket 200, and the other end is hinged to the drilling rig platform 600, and the lifting mechanism is used to drive the drilling rig platform 600 to lift and lower back and forth, and the lifting mechanism and the telescopic cylinder 410 are respectively arranged near the two ends of the drilling rig platform 600. The sliding bracket 200 can drive the drilling rig body to move horizontally, that is, to move along the section to be punched, so as to perform interval drilling, so that the drilling rig body can quickly move into position for drilling. The provided lifting mechanism and telescopic cylinder 410 can adjust the height and angle of the drilling rig body to adapt to different situations.

[0025] As mentioned above, the sliding bracket 200 reciprocates on the sliding track 100 through a traveling mechanism. Specifically, the traveling mechanism includes a traveling gear 500 and a traveling motor installed on the sliding bracket 200. A rack 510 meshing with the traveling gear 500 is provided along the length direction of the sliding track 100. The traveling motor drives the traveling gear 500 to rotate and thus generates displacement on the rack 510. The sliding bracket 200 is driven by the traveling motor and the traveling gear 500 to realize the movement of the drilling rig body.

[0026] The sliding bracket 200 is arranged on the sliding track 100. In order to improve the stability of the sliding bracket 200, the sliding track 100 is arranged to include a base and two monorails 101 fixedly arranged on the base. The sliding bracket 200 spans over the two monorails 101. A sliding plane in contact with the monorails 101 is arranged on the side of the sliding bracket 200 away from the running gear 500. There is also a clearance groove between the two monorails 101. The locking mechanism is located on the outer side of the sliding bracket 200 and extends into the clearance groove. The two side walls of the clearance groove are respectively provided with inwardly recessed brake slots 110. The locking mechanism includes two movable claws 300 and a locking cylinder 310 driving the claws 300. The claws 300 are pressed against the brake slots 110 under the drive of the locking cylinder 310 to lock the sliding bracket 200. The sliding bracket 200 is fixed and released by the locking mechanism, which facilitates the conversion between the drilling operation and the position adjustment. Specifically, the two claws 300 are respectively rotatably connected to the sliding bracket 200, and the two ends of the locking cylinder 310 are respectively hinged to the two claws 300. When the locking cylinder 310 contracts, the two claws 300 are pulled toward the middle to separate from the brake slot 110. When the locking cylinder 310 extends, the two claws 300 are pushed to expand outward and then clamped into the brake slot 110.

[0027] As part of the adjustment component, the lifting mechanism includes a screw nut pair and a lifting motor. Specifically, the nut 401 of the screw nut pair is hinged on the drilling platform 600, and the lifting motor and the screw 400 of the screw nut pair are both installed on the sliding bracket 200. The sliding bracket 200 is also vertically provided with a vertical frame 210, and the screw 400 is installed on the vertical frame 210. When adjusting the drilling platform 600 (drilling rig body), the lifting mechanism and the telescopic cylinder 410 cooperate with each other. For example, when the overall height of the drilling platform 600 needs to be lifted horizontally, the drilling platform 600 needs to be lifted to a set height by the lifting mechanism, and the telescopic cylinder 410 needs to be extended to support the other end of the drilling platform 600. When the pitch angle of the drilling platform 600 needs to be adjusted, the lifting mechanism can be kept stationary, and the telescopic cylinder 410 can be used to lift or pull down the side of the drilling platform 600 away from the lifting mechanism to achieve the purpose of adjusting the angle of the drilling platform 600.

[0028] The drilling rig body includes a power motor 610 and a drill rod 630. The power motor 610 is installed at one end of the drilling rig platform 600. A guide sleeve 620 is provided at the other corresponding end of the drilling rig platform 600. One end of the drill rod 630 is transmission-connected to the power motor 610, and the other end of the drill rod 630 passes through the guide sleeve 620. In order to automatically push the drill rod 630 to move into the coal seam to achieve drilling, a sliding base is slidably provided on the drilling rig platform 600, the power motor 610 is fixedly installed on the sliding base, and a propulsion cylinder 640 for driving the sliding base is provided on the side of the drilling rig platform 600. A connecting portion is provided on the side of the sliding base extending downward, and the connecting portion is hinged to the movable end of the propulsion cylinder 640. The corresponding fixed end of the propulsion cylinder 640 is fixedly provided at the end of the drilling rig platform 600, that is, the connecting portion of the sliding base is located near the middle of the drilling rig platform 600, and the propulsion cylinder 640 pushes the power motor 610 and the drill rod 630 to extend forward on the drilling rig platform 600 to achieve the purpose of drilling.

[0029] Preferably, the lifting motor, the power motor 610 and the travel motor are all hydraulic motors. In order to optimize the structure, the lifting motor and the travel motor are combined into one, and a dual-purpose motor 700 can be used to complete the task. The dual-purpose motor 700 is connected to the travel gear 500 and the lead screw 400 through a clutch structure.
