[0034] Example 1: Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The present invention provides a technical solution: a rapid drilling device for a coal mine tunnel drilling rig, comprising a main body mechanism 1, the main body mechanism 1 comprising a body assembly 11, two support columns 14 are fixedly installed on the front and back of the body assembly 11, a console 13 and an oil tank 12 are fixedly installed on the upper surface of the body assembly 11, an oil pump assembly 15 is fixedly installed on the upper surface of the body assembly 11, and a drill rod installation mechanism 2 is arranged on the outer side of the body assembly 11;

[0035] The drill rod installation mechanism 2 includes a drill rod support unit 21, which is located at the front and rear sides of the machine body assembly 11. The drill rod support unit 21 is used to place the drill rod and the drill bit instead of manual lifting.

[0036] As a further limitation of the drill rod installation mechanism 2 of the present invention, the drill rod support unit 21 includes two groups of bases 2101, each group of bases 2101 is located below the body assembly 11, and a slide groove 2109 is provided on the upper surface of each group of bases 2101. A limiting block 2110 is slidably connected to the interior of each slide groove 2109, and a connecting angle plate 2102 is fixedly installed on the upper surface of each limiting block 2110. The bottom surface of each connecting angle plate 2102 is in contact with the upper surface of the base 2101, and a multi-section telescopic slide 2105 is fixedly installed on the outer end surface of each connecting angle plate 2102. The side of each multi-section telescopic slide 2105 away from the base 2101 is fixedly connected to the side of the body assembly 11 close to the base 2101, and the side of each connecting angle plate 2102 close to the base 2101 is fixedly installed There are hydraulic push rods 2104, and the telescopic end of each hydraulic push rod 2104 is fixedly installed with a connecting steel plate 2103. The side of each connecting steel plate 2103 close to the connecting angle plate 2102 is fixedly connected to the side of the base 2101 close to the body assembly 11. A plurality of identical rollers 2107 are commonly arranged inside the two bases 2101, and the outer surface of each roller 2107 is provided with a rod groove 2106. By providing a drill rod support unit 21, the drill rod support unit 21 can facilitate the temporary storage of drill rods and drill bits, and can adjust the height of the drill rods and drill bits, so as to facilitate the subsequent installation and supply of drill bits and drill rods, which is conducive to saving manpower when installing drill rods and drill bits, and the drill rod support unit 21 can be retracted under the body assembly 11 to avoid occupying too much space when the drill rod support unit 21 is not in use;

[0037] See also Figure 5 and Figure 7 , each base 2101 is fixedly inlaid with a plurality of identical rolling bearings 2111, and the inner wall of each rolling bearing 2111 is fixedly connected to the outer surface of the roller 2107.

When the base 2108 touches the ground, the multi-section telescopic slide 2105 is stopped. Then, the drill rod and the drill bit can be directly placed in the rod groove 2106. When the drill rod and the drill bit are pushed in the rod groove 2106, they are supported and transmitted by the roller 2107, and the drill rod and the drill bit are placed on the roller 2107 in a rolling manner, waiting for the drill rod and the drill bit to be used. During the installation of the drill rod and the drill bit, when the base 2101 and the roller 2107 are not needed, in order to avoid taking up too much space, the multi-section telescopic slide 2105 can be retracted to make the base 2108 leave the ground, and then the hydraulic push rod 2104 can be started. The hydraulic push rod 2104 drives the base 2101 to move toward the machine body assembly 11 through the connecting steel plate 2103. During the movement of the base 2101, the limiting block 2110 moves in the slide groove 2109, which can both support the base 2101 and prevent the base 2101 from falling off.

[0040] Example 2: Please refer to Figure 1 , Figure 8 and Fig. 9 The present invention provides a technical solution: a rapid drilling device for a coal mine tunnel drilling rig. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0041] As a further limitation of the drill rod installation mechanism 2 of the present invention, the drill rod installation mechanism 2 also includes a drill rod clamping unit 22, the drill rod clamping unit 22 is located above the drill rod supporting unit 21, and the drill rod clamping unit 22 is used to clamp the drill rod and the drill bit, and to move and install the drill rod and the drill bit;
