Embodiment 1

[0032] Example 1, such as Figure 1 to Figure 4 As shown, an automatic lifting drilling rig for high-level drilling in medium-thick coal seams includes a lifting unit, a power unit, a rotary unit, a walking unit and a drilling unit. The lifting unit is connected to the rotary unit and the drilling unit, and the power unit is connected to the lifting unit and the rotary unit. , walking unit and punching unit.

[0033] The lifting unit includes a front hydraulic cylinder 11 and a rear hydraulic cylinder 14. The front hydraulic cylinder 11 and the rear hydraulic cylinder 14 are two-stage telescopic hydraulic cylinders. The cylinder bodies of the front hydraulic cylinder 11 and the rear hydraulic cylinder 14 pass through movable pin holes respectively. Fixed on the front and rear ends of the rotary unit, the piston rod of the front hydraulic cylinder 11 and the piston rod of the rear hydraulic cylinder 14, the front hydraulic cylinder 11 and the rear hydraulic cylinder 14 are arra...

Abstract

The invention discloses an automatic lifting drilling rig for high-position drilling in medium-thick coal seams, which includes a lifting unit, a rotary unit and a drilling unit. The lifting unit includes a front hydraulic cylinder and a rear hydraulic cylinder, and cylinder bodies of the front hydraulic cylinder and the rear hydraulic cylinder It is fixed on the rotary unit, and the piston rods of the front hydraulic cylinder and the rear hydraulic cylinder are connected with the punching unit. It has the following advantages: It solves the problem that the existing drilling rig cannot effectively drill holes at high positions in medium-thick coal seams and the adjustment of the drilling angle is inflexible. It can automatically lift and adjust the drilling pitch angle, and can adjust the horizontal rotation angle. Hole efficiency and safety are improved.

Description

technical field [0001] The invention relates to an automatic lifting drilling machine for high-position drilling in medium-thick coal seams and a realization method thereof, belonging to the field of coal mine drilling machinery equipment. Background technique [0002] At present, in the high-level drilling construction of medium-thick coal seams in underground coal mines, auxiliary devices such as temporary supports and chain hoists are generally used to increase the drilling height of the drilling rig. Stability, resulting in accidents such as drill sticking are extremely prone to occur during construction. [0003] The chassis and fuselage of existing coal mine crawler drilling rigs generally adopt a fixed connection method, and the horizontal azimuth of drilling can only be adjusted by adjusting the differential speed of the crawler traveling mechanisms on both sides. lead to low construction efficiency. [0004] The existing patent application number 200920103136.X di...
