Problems solved by technology

However, for the rotary seal structure, the oil pressure is high, and the rapid rise of the internal oil temperature will cause damage to the bearings and seals inside the structure, greatly reducing the reliability of the product
[0007] After years of rapid development of coal mining, the current annual mining volume of coal is extremely huge. Only relying on the mining of shallow coal seams can no longer fully meet the domestic demand for coal, but the geological mining of deep coal seams is more difficult, so the directional drilling rigs currently used in Structural design, stability, reliability and power usage cannot meet the requirements for directional drilling rigs

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] As shown in Fig. 1, it is a schematic structural view of the coal mine tunnel directional drilling machine of the present invention, which includes a drilling car 1 and a pump car 5. The drilling rig 1 includes an oil tank 2 , a rear clamping portion 3 and an oil distribution sleeve 4 .

[0032] As an embodiment, the pump truck 5 can also be integrated with the drilling truck 1 according to actual conditions.

[0033] In the structure of directional drilling rig, due to the large volume of the hydraulic oil tank, it needs to occupy more space, but the space of the underground tunnel is generally relatively narrow, and the requirements for the size of the equipment are relatively strict, so the structure of the oil tank greatly affects the setting of other components and various pipes. Therefore, the present invention adopts that the fuel tank 2 is submerged and...

Abstract

The invention provides a coal-mine underground-adit directional drilling machine. The coal-mine underground-adit directional drilling machine comprises a drill carriage and a pump truck. The drill carriage mainly comprises a carriage body, a clamping mechanism, an oil tank and an oil distribution sleeve. The clamping mechanism comprises a front clamping part and a rear clamping part, the front clamping part and the rear clamping part are sequentially arranged on a feed frame of the drill carriage, the oil distribution sleeve comprises a cylinder barrel and a piston, and the position between the piston and the cylinder barrel is of a double-oil-line rotary sealed type structure. The coal-mine underground-adit directional drilling machine has the characteristics of being simple and convenient in structure, compact in space, safe and reliable and the like.

Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to an underground tunnel directional drilling machine for coal mines. Background technique [0002] The underground tunnel drilling rig is mainly used for the construction of directional drilling in various projects such as gas pumping (discharging) in coal mines, grouting for fire prevention, coal seam water injection, coal seam thickness survey, outburst pressure relief, geological exploration, etc., and other special requirements underground drilling needs. [0003] Constrained by the space size of the tunnel and the influence of various harsh working conditions, and due to the large inclination angle of the underground roadway, it is required to have a reasonable design plan for the structural volume and reliability of the whole machine. Therefore, a reasonable overall layout of the drilling rig and the structural design of each component are also an important technical link ...
