Novel pure-electric rock drill

Abstract

The invention discloses a novel pure-electric rock drill. The novel pure-electric rock drill comprises a drill bit connection board, a storage battery case, a handle connection board and a drill body. The storage battery case is fixedly mounted on the top of the drill body. A storage battery is arranged in the storage battery case. The handle connection board is welded to the rear end of the drill body. Outward-stretching rods are fixed to the two sides of the drill body. A drill bit is mounted in a threaded groove in the front end of the drill bit connection board. Front buffer boards are welded to the two sides of the top of the drill body and fixedly provided with buffer springs respectively and correspondingly. The other ends of the buffer springs on the two sides are fixed to a spring connection board which is fixed to the top of the drill body. A socket is mounted at the rear end of the top of the drill body and connected with the storage battery case through a wire. Side boards are mounted on the outward-stretching rods on the two sides correspondingly. The other ends of the side boards are fixed to two ends of a handle. Rubber covers are mounted on the two sides of the handle. The novel pure-electric rock drill has the beneficial effects that by means of the storage battery type pure-electric rock drill, dependence on a transformer case is eliminated, and the rock drilling efficiency is improved in cooperation with a series of buffering and damping mechanisms.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a novel pure electric rock drill. Background technique [0002] With the rapid development of the national economy, construction machinery has become an economic pillar industry. As a kind of construction machinery, internal combustion rock drills have the functions of mining drilling, Building Construction , cement pavement, asphalt pavement and other functions such as splitting, crushing, tamping, shoveling, etc., widely used in mining, construction, fire protection, Geological exploration , road construction, quarrying, construction, national defense engineering, etc. Rock drills are divided into four types: pneumatic, electric, internal combustion and hydraulic. rock. It is suitable for construction sites without power supply and air source. The hydraulic type relies on hydraulic pressure to impact steel drills and chiseling rocks through inert gas and impa...

AI Technical Summary

Problems solved by technology

It is suitable for construction sites without power supply and air source. The hydraulic type relies on hydraulic pressure to impact steel drills and chiseling rocks through inert gas and impact bodies. The distance operation brings many disadvantages to the progress of the project, so there is an urgent need for a new type of pure electric rock drill to make up for these shortcomings
