Hydraulic rock drilling machine

Abstract

The invention relates to engineering machines, in particular to a hydraulic rock drilling machine. The hydraulic rock drilling machine is composed of a hydraulic carrier machine A and a drilling machine B. The hydraulic carrier machine A is an excavator, or a loader or a forklift, and according to the hydraulic rock drilling machine, a working device at the front end of the hydraulic carrier machine A serves as a machine base. Hydraulic oil provided by a hydraulic system of the hydraulic carrier machine and a selectively matched air compressor are used as power sources, and the drilling machine B is installed at the front end of the working section of the hydraulic carrier machine A. The working device at the front end of the excavator, or the loader or the forklift is adopted as the machine base in cooperation with the drilling machine to perform rapid and efficient rock drilling. The hydraulic rock drilling machine is rapid and convenient to install and detach, easy to maintain, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to an engineering machine, in particular to a hydraulic rock drilling rig. Background technique [0002] At present, the high difficulty and particularity of road construction and related projects in our country have strengthened our dependence on high-performance rock drilling rigs. Our country spends a lot of money every year to import a considerable number of rock drilling rigs from abroad. Funds, and the maintenance and repair of trolleys are also quite difficult. The integrated hydraulic rock drilling machine has the advantages of high power density and high operating efficiency, but it has relatively high technical requirements and is expensive, and the price of each unit is more than 2 million yuan. Pneumatic rock drilling machinery has the advantages of simple structure and low technical requirements, but the power density is low, the operating efficiency is low, and the entire system is bulky, and it usually needs to be ...

[0002] At present, the high difficulty and particularity of road construction and related projects in our country have strengthened our dependence on high-performance rock drilling rigs. Our country spends a lot of money every year to import a considerable number of rock drilling rigs from abroad. funds, and the maintenance and repair of the trolley is quite difficult

The integrated hydraulic rock drilling machine has the advantages of high power density and high operating efficiency, but the technical requirements are relatively high and the price is expensive. The price of each unit is more than 2 million yuan

Pneumatic rock drilling machinery has the advantages of simple structure and low technical requirements, but the power density is low, the operating efficiency is low, and the entire system is large in size, and usually needs to be used with an air compressor, which is costly

[0003] When the existing excavator hydraulic rock drilling air compressor device is installed on the excavator platform, the back pressure caused by too long pipeline is too high, the slag discharge ability of the air compressor is poor, the pipeline layout is complicated, and it is inconvenient to install
