Embodiment Construction

[0014] Such as figure 1 As shown, a drilling rig for mines includes a base 1, on which a support 2 is fixed, on which a slide rail 3 is arranged, on which the slide rail 3 of the support 2 is slidably equipped with power for driving a drill rod 4 The driving device, the power driving device reciprocates on the bracket. In this embodiment, the power driving device is a gyrator 7, and the front end of the bracket 2 is fixed with a supporting device 6 for cooperating with the gyrator 7 to support the drill pipe 4. The device 6 is provided with a support hole for sliding engagement with the drill rod 4, and the displacement sensor 5 for detecting the total displacement of the drill rod 4 relative to the support 2 is arranged on the support device 6, and is also provided on the support device 6 for The counter that counts the number of standard drilling rods 4 passing through the support hole, what the counter in the present embodiment uses is an infrared counter 11, and the signal...

Abstract

The invention discloses a drilling machine for mines, comprising a support on which a power driving device for driving a drill stem is slidably arranged, and the power driving device makes an alternating motion on the support on which a displacement sensor for detecting the total displacement of the drill stem relative to the support is also arranged. Because the displacement sensor for detectingthe total displacement of the drill stem is arranged on the support, the drilling machine for mines is used for measuring the drilling depth by detecting the total length of the drill stem punched toa drill hole by the power driving device, thereby realizing the accurate measurement of the hole depth. The drilling machine for mines has the advantages of simple structure, convenience and practicality and realizes the detection on the hole depth during drilling so as to avoid the influence of drilling collapse or protrusion in the mines on detecting the hole depth after drilling and ensure thenormal production.

Description

technical field [0001] The invention relates to a drilling machine for mines. Background technique [0002] Existing mine drilling rigs mainly include 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. After a certain progress is drilled, the gyrator retracts a certain distance along the slide rail axis. , 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 working drill pipes of equal length are driven into the coal seam ...
