Abstract

The invention relates to the technical field of building construction equipment, and discloses a rock drill for building construction. The rock drill comprises a machine body, wherein handles are fixedly installed on the two sides of the top of the machine body. According to the rock drill for building construction, through cooperation of a sliding plate, a first spring, a telescopic box and a second spring, vibration generated in the process of collision of a piston and a drill sleeve and a drill rod and collision of the drill sleeve and the drill rod and the ground cannot be directly transmitted to a shell of the machine body, vibration force can be absorbed by the first spring and the second spring firstly, and then when a worker holds the handles, the borne vibration force is reduced; through sleeving of a positioning sleeve and fixing of a clamping jaw, the breaking position of the drill sleeve and the drill rod is fixed by the positioning sleeve, and the problem that due to clearance sleeving of the machine body and the drill sleeve, the drill sleeve and the drill rod are inclined when colliding with the ground, and the sliding breaking effect is poor is solved; and vibration of collision of the drill sleeve and the drill rod drives the positioning sleeve to vibrate, the vibration cannot be transmitted to the machine body along with a chain, and the vibration force of the handles is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a rock drilling machine for building construction. Background technique [0002] A rock drill is a tool used to directly mine stone. It drills blastholes in the rock formation, so that explosives can be put in to blast the rocks, so as to complete the mining of stones or other stone works. In addition, the rock drill can also be converted into a breaker to break hard layers such as concrete. [0003] When the pneumatic rock drill is used to break the hard layer of concrete, the air compressor injects high-pressure gas into the reversing valve inside the rock drill. The high-pressure gas first enters the upper part of the piston, pushes the piston down and hits the drill rod, and the drill rod performs stroke work. The hard layer is impacted and broken, and then the high-pressure gas is under the action of the reversing valve, and the high-pressure gas is...
