DETAILED DESCRIPTION

[0037] 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 of 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.

[0038] See also Figure 1-12A full-range coal mine top cutting drill vehicle comprises a vehicle body 1, a mounting plate 2 is fixedly mounted on one side of a mounting plate 2, the mounting plate 2 is arranged in front of the vehicle body 1, a cross support frame 3 is fixedly mounted on the upper surface of the mounting plate 2, two semicircular adjustment rings 4 are arranged above the cross support frame 3, and the semicircular adjustment rings 4 are rotatably connected to the ends of the cross support frame 3, and the two semicircular adjustment rings 4 cross each other. It is worth noting that the radii of the two semicircular adjustment rings 4 are different, so that the two semicircular adjustment rings 4 rotatably connected to the ends of the cross support frame 3 can cross smoothly, a slide groove 14 is opened in the middle of the semicircular adjustment ring 4, and a directional adjustment slider 9 is slidably connected to the inner side of the slide groove 14, and the directional adjustment slider 9 is located at the intersection of the semicircular adjustment rings 4, that is, the directional adjustment The section slider 9 is slidably connected with the two semicircular adjustment rings 4 at the same time. A hydraulic cylinder 17 is fixedly installed at the lower end of the directional adjustment slider 9. A root column 7 is fixedly installed at the lower end of the hydraulic cylinder 17. The root column 7 is spherically connected to the middle of the upper surface of the cross support frame 3. A clearance through hole 16 is opened in the middle of the upper surface of the directional adjustment slider 9. A drill bit 18 is fixedly installed at the output end of the hydraulic cylinder 17. The drill bit 18 can perform drilling operations. The drill bit 18 is a prior art, so it will not be described in detail. A motor 20 is fixedly installed on the upper surface of the mounting plate 2. The output end of the motor 20 is connected to the semicircular adjustment ring 4. When the motor 20 drives the semicircular adjustment ring 4 to rotate, the intersection of the two semicircular adjustment rings 4 will change, and at the same time, it is slidably connected to the two semicircular adjustment rings 4. The internal directional adjustment slider 9 also changes with the change of the intersection of the semicircular adjustment ring 4. Since the root column 7 fixedly installed at the lower end of the hydraulic cylinder 17 is spherically connected to the cross support frame 3, the upper end of the hydraulic cylinder 17 is fixedly connected to the lower surface of the directional adjustment slider 9, so that when the position of the directional adjustment slider 9 slidably connected inside the semicircular adjustment ring 4 changes, the directional adjustment slider 9 drives the upper end of the hydraulic cylinder 17 to move, thereby changing the direction of the hydraulic cylinder 17, thereby changing the working position of the drill bit 18 fixedly installed at the output end of the hydraulic cylinder 17. By telescoping the hydraulic cylinder 17, the distance between the drill bit 18 and the vehicle body 1 can be changed. When the drill bit 18 is drilling, the depth of the drill bit 18 can be controlled by telescoping the hydraulic cylinder 17. As described above, first, the top cutting drill vehicle drives the direction adjustment slider 9 slidably connected thereto to move by rotating the semicircular adjustment ring 4, thereby changing the direction of the hydraulic cylinder 17 and further changing the external position of the drill bit 18. Second, by telescoping the hydraulic cylinder 17, the external position of the drill bit 18 is changed, and the depth of the hole drilled by the drill bit 18 is controlled, so that the top cutting drill vehicle can drill holes in all directions. The top cutting drill vehicle drives the direction adjustment slider 9 through the crossed semicircular adjustment rings 4 to change the direction of the hydraulic cylinder 17, so that the drill bit 18 fixedly installed at the output end of the hydraulic cylinder 17 obtains a range of motion greater than the telescopic range of the hydraulic cylinder 17. While ensuring that the drill bit 18 has a larger range, the space occupied by the top cutting drill vehicle is reduced, making it more convenient to move the top cutting drill vehicle in the mine.

After tightening the bolts, the rotation connection between the semicircular adjustment ring 4 and the cross support frame 3 is completed. By arranging the anti-shear protrusions 13 abutting against the two ends of the arc fork 15, the shear force on the bolts used to connect the cross support frame 3 and the semicircular adjustment ring 4 can be reduced. A connecting shaft 19 is provided at one end of the semicircular adjustment ring 4. The connecting shaft 19 is fixedly installed on the side of the isolation ring 6 away from the rotating seat 5 by bolts. It is fixedly installed at the output end of the motor 20 to realize the connection between the motor 20 and the semicircular adjustment ring 4.
