Embodiment Construction

[0013] Such as figure 1 As shown, the mine drilling machine includes a base 1, a support 2 is fixed on the base 1, a slide rail 3 is arranged on the support 2, and a power drive device for driving the drill rod 4 is slidably mounted on the slide rail 3 of the support 2, The power drive device reciprocates on the support. In this embodiment, the power drive device is a gyrator 7. A support device 6 for coordinating with the gyrator 7 to support the drill pipe 4 is fixed at the front end of the support 2. On the support device 6 A support hole for slidingly fitting with the drill rod 4 is provided, a displacement sensor 5 for detecting the total displacement of the drill rod 4 relative to the support 2 is provided on the support device 6, and a displacement sensor 5 for detecting the total displacement of the drill rod 4 relative to the support 2 is provided on the support device 6. A counter for counting the number of standard drill pipes 4 in the hole, what the counter in the ...

Abstract

The invention discloses a mine drilling machine. The machine comprises a bracket, wherein a power driving device for driving standard drill stems with equal lengths is slidably arranged on the bracket and does reciprocating motion on the bracket; and the bracket is also provided with a counter for counting the number of standard drill stems driven by a power device. In the mine drilling machine, the bracket is provided with the counter for counting the number of drill stems drilled into drill holes by the power driving device and the drill stems are standard drill stems with equal lengths, sothat the depth of each drill hole can be obtained by multiplying the measured number of the drill stems by the standard length of the drill stem and the hole depth is measured correctly. The machine has the advantages of realizing detection of the hole depth while drilling, avoiding the effect of collapse of the drill hole or projection of the drill hole on a mine on the detection of the hole depth after drilling and ensuring normal production, along with simple structure, convenience and practicability.

Description

technical field [0001] The invention relates to a mine drilling machine. Background technique [0002] The existing mine drilling rig mainly includes a base, on which a bracket is fixed, and a slide rail is provided on the bracket, and a gyrator as a power drive device is slidably mounted on the slide rail, and the gyrator performs reciprocating motion on the slide rail. During the drilling process, the gyrator clamps and fixes the drill pipe and drives the drill pipe to rotate and drill. At the same time, the gyrator slides axially along the slide rail with the drill pipe. Clamp another drill pipe again and drive it to rotate and drill, and repeat the above actions. The drill pipe is driven by the gyrator and screwed into the coal seam wall, and through the reciprocating motion of the gyrator, standard drill pipes of equal length are driven into the coal seam wall one by one to achieve the purpose of drilling. When it is necessary to take out the standard drill pipes in t...
