Embodiment Construction
[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.
[0031] Such as figure 1 , figure 2 with image 3 Shown, the double crawler drilling rig for coal mine of the present invention comprises drilling machine frame, power head 24 and holder 7, and drilling machine frame comprises frame body 25 and drilling rig propulsion oil cylinder 5, is used for supporting power head and realizing power head Forward and backward, the power head is fixed on the carriage with a pin shaft, and under the action of the propulsion cylinder, the carriage and power head are driven to reciprocate along the guide rail of the upper frame; the rack adjustment cylinder is used to adjust the position of the rack. The inclination angle is fixed by...

The invention discloses a double-caterpillar drilling machine used in coal mines, comprising a drilling machine rack, a power head and a clamp holder, wherein the drilling machine rack comprises a rack body, a drilling machine thrust cylinder and a rack slope regulating cylinder; the drilling machine comprises a drilling vehicle system and an operation vehicle system; the drilling vehicle system comprises a drilling caterpillar vehicle and a drilling caterpillar rack and a drilling vehicle support walking slope regulating system which are arranged on the drilling caterpillar vehicle; the operation vehicle system comprises an operation caterpillar vehicle and the operation caterpillar rack arranged on the operation caterpillar vehicle; the operation caterpillar vehicle is also provided with an operation vehicle support walking system; and the power head, the clamp holder, the rack slope regulating cylinder and the drilling machine thrust cylinder are controlled by a hydraulic control system. The difference between the structure of the invention and that of the traditional drilling machine lies in that the double-caterpillar machine in the invention is composed of a drilling vehicle system and an operation vehicle system; as the whole structure is divided into two small caterpillar vehicle structures, the whole size is shortened, the operation is more flexible, thus being convenient to be used in the coal mines with small tunnels or with special requirements.
Description
technical field [0001] The invention relates to the field of mining machinery, in particular to a double-crawler drilling rig for coal mines. Background technique [0002] Existing drilling rigs are mostly integrated structures, mainly composed of pump stations, consoles, racks, underframes, holders, columns, drilling tools, etc. For coal mines that are small or have special requirements for use, the use effect is not ideal. Therefore, it is necessary to study a drilling rig system suitable for the use requirements of these special coal mines. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of double-crawler drilling rig for coal mine, which is made up of a drilling vehicle system and an operating vehicle system. Since the overall structure is divided into two small crawler vehicle structures, its overall size can be reduced. It is convenient to use in coal mines with small roadways or special requirements. ...
