Novel efficient impact drilling machine

Abstract

The invention relates to the technical field of impact drilling machine equipment, and provides a novel efficient impact drilling machine which comprises a machine frame. A driving rear axle is connected to the rear side wall of the machine frame. The novel efficient impact drilling machine is characterized in that the driving rear axle is provided with two steel wire ropes, and the two steel wireropes pass through a stand column and are connected to a same drill bit. The defects in the prior art are overcome, the design is reasonable, the structure is compact, and the problems of low impactefficiency, poor effect and no sand discharge of an existing impact drilling machine are solved. Through the simple structural combination, by adopting the two steel wire ropes to be connected with the dill bit, the stability of the drill bit is improved, meanwhile, a mode that a smaller gear is meshed with a large gear is adopted to improve output power, the drill bit with the large weight can bedriven to work, the work efficiency is improved, strong airflow produced by an air compressor is used for discharging sand, and therefore the effect of quickly discharging the sand is realized.

Description

technical field [0001] The invention relates to the technical field of percussion drilling rig equipment, in particular to a novel high-efficiency percussion drilling rig. Background technique [0002] The percussion drilling rig is a machine that uses the impact force of the drill bit to punch holes in the rock formation. Impact drilling rigs are very common in road and bridge construction and mining. At present, traditional impact drilling rigs use a winch to tighten and loosen the wire rope, and then the wire rope drives the drill bit to move up and down for impact. [0003] But the traditional impact drill still has the following problems: [0004] 1. The traditional percussion drilling rig often drives the winch directly through the motor to tighten or loosen the wire rope, which makes the motor load larger and more laborious. Therefore, it is equipped with a drill bit with a smaller weight, which has poor impact effect and low work efficiency. [0005] 2. Most of the...

Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides a new type of high-efficiency percussion drilling rig, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and solves the problem of low impact efficiency and poor effect of the existing percussion drilling rigs. , and does not have the problem of sand discharge, the present invention uses two steel wire ropes to connect the drill bit through a simple structure combination, which improves the stability of the drill bit. The heavy drill bit works to improve the working efficiency, and the powerful airflow generated by the air compressor is used to discharge the sand and gravel from the sand pumping pipe, so as to achieve the effect of rapid sand discharge, which has strong practicability
