Embodiment Construction

[0020] Below in conjunction with accompanying drawing this embodiment will be further described

[0021] Depend on Figure 1-2It can be seen that the front vehicle frame 32 is based on the front vehicle, and each mechanism component is fixed on it with a connecting piece. Wherein both sides are equipped with walking device 21 and ground anchor cylinder 28; its front and rear respectively two lower supporting oil cylinders 19, each upper supporting oil cylinder 2 in the left front and left rear, two front supporting oil cylinders 35 in the front, respectively used for stabilizing the drilling rig, Provide support guarantee for drilling. Front vehicle frame 32 right sides arrange front holder 3, blocking device 4, shackle 5, holder 6, speed reducer 7, pulley 8, double motor 36 and support bar mechanism 12 successively from front to back. Wherein the holder 3 is fixed on the bracket 16 on the front frame 32 with a connecting piece; the blocking device 4 is fixed on the shackle ...

Abstract

The invention relates to a coal mine tunnel drilling rig, specifically relates to a drilling rig which can perform super-deep hole directional drilling in non-soft coal layers and perform deep hole double-tube directional drilling in soft coal layers and solves the problem that existing drilling rigs can not perform super-deep hole directional drilling in the non-soft coal layers and can not perform deep hole directional drilling in the soft coal layers. According to the drilling rig, two power heads, a shackle mechanism and a clamp holder are mutually cooperated; by means of a combination drilling mode which combines technologies of hole bottom dynamic directional drilling, sleeve revolving drilling and hole deslagging, the problem of hole collapse in the soft coal layers can be solved, and drilling efficiencies are improved; the drilling rig uses a split self-walking structure, the whole drilling rig can independently walk when the drilling rig is divided into two parts, the size of the whole drilling rig is controlled, and adaptivity to a roadway is improved; a feed mechanism uses a hydraulic motor to drive a spiral pair to provide feed forces so that the two power heads can achieve large-stroke independent action and coordination action on the same axis; and the drilling rig is provided with a support oil cylinder and a ground anchor cylinder and is high in intensity of a rig body and work stability.

Description

technical field [0001] The invention relates to a coal mine tunnel drilling machine, in particular to an ultra-deep hole double-pipe drilling directional drilling machine. Background technique [0002] The geological conditions of my country's coal mines are extremely complex, and there is a large amount of gas associated with coal, which seriously restricts the production efficiency of coal mines. The effective way to control gas is to extract (release) coal or rock boreholes. It is an effective way to improve coal mine productivity by implementing large-area drilling for pre-drainage. At present, there are two kinds of tunnel drilling rigs used for gas drainage drilling in coal mines, one is a power directional drilling machine at the bottom of the hole; the other is a rotary power drilling machine at the hole. They are all unable to carry out the directional drilling of ultra-deep holes (more than 1500m) and the directional drilling of deep holes (more than 600m) in sof...
