Description

Rock drilling machine

Technical Field

The utility model belongs to the rig, in particular to dedicated rig of rock.

Background

The prior rock construction mostly adopts a winch impact drilling machine, and a heavy drill bit is hoisted by a winch to smash, so that the rock is crushed, and the surrounding environment is influenced to a certain extent. The construction progress is slow, and is with high costs, seriously influences the engineering progress. The other type is a large-scale rotary drilling machine, the machine purchasing cost is high, a diesel engine is used as power, the use cost is also high, and fuel oil can pollute the environment. Due to the influence of the rotating speed, the drilling speed is low, the construction cost is high, and the resource waste is serious.

Disclosure of Invention

In order to overcome the shortcoming of the prior art, the utility model provides a rock drilling machine, it utilizes many drill bits, creeps into fast, and the benefit is high, and is with low costs, and the noise is little.

The utility model provides a technical scheme that its technical problem adopted is: the large frame is a frame structure formed by fixing four stand columns, a power head is arranged on the large frame in a sliding fit mode through a vertical guide rail, a lifting oil cylinder is hinged between the power head and the large frame and drives the power head to move up and down, a drill rod motor, a slurry pump and a slurry pump motor are fixed to the upper end of the power head, the slurry pump is driven by the slurry pump motor, an output shaft of the drill rod motor is fixed to an input shaft of the power head and used for driving the power head, a drill rod is fixed to the output shaft of the power head through a slow rod, and a drilling; the drilling device comprises a drill bit frame, the upper end of the drill bit frame is fixed with the drill rod, the lower end of the drill bit frame is fixed with a power distribution box, the power distribution box is provided with a plurality of output shafts, drill bits are respectively fixed on the output shafts, an input shaft of the power distribution box is fixed with an output shaft of a speed reducer fixed on the drill bit frame, an input shaft of the speed reducer is driven by a motor, and the motor is fixed with the speed reducer.

The utility model discloses there are following: 1) the motor is used as power, the cost is low, the noise is low, and the surrounding environment is not affected. The multi-drill bit has high rotation speed, fast drilling, high benefit, energy saving, labor saving and time saving; 2) the speed is improved by 9 times compared with that of an impact drilling machine, and the cost is reduced by 100 percent; compared with a large rotary drilling rig, the speed is improved by 2 times, and the cost is reduced by 20%.
