Full-hydraulic rock-drilling excavator using hydraulic excavator for production

Abstract

The invention discloses a full-hydraulic rock-drilling excavator using a hydraulic excavator for production. The full-hydraulic rock-drilling excavator is an engineering machine which combines functions of a full-hydraulic rock-drilling drilling machine and a conventional excavator and comprises a hydraulic excavator (A) and a full-hydraulic drilling machine (B), wherein a helical-lobe compressor(2) and a power regulation device (4) are arranged on a conventional hydraulic excavator top form the hydraulic excavator (A), confluence of two groups of high-pressure oil pumps of the hydraulic excavator, which are in parallel connection is achieved, output from stand-by valve sets is achieved, and the helical-lobe compressor (2) and the full-hydraulic drilling machine (B) are driven respectively through the power regulation device (4); the helical-lobe compressor (2) provides required compressed air for the full-hydraulic drilling machine (B); and the full-hydraulic drilling machine (B) is installed at a bucket position of the hydraulic excavator (A). The full-hydraulic rock-drilling excavator can maintain original functions of the hydraulic excavator and can be connected with other accessories which require hydraulic drive conveniently, functions of the full-hydraulic rock-drilling excavator can be replaced in a few minutes, and multiple purposes are achieved.

Description

technical field [0001] The invention relates to an engineering machine, in particular to a full hydraulic rock drilling excavator produced by a hydraulic excavator which takes into account the functions of a full hydraulic rock drilling rig and a traditional excavator. Background technique [0002] my country is a mountainous country, and it is also a country with energy shortages. However, the pneumatic rock drilling equipment with a very large market share generally has the problems of high energy consumption and low production efficiency. In recent years, the full-hydraulic rock drilling rigs imported from abroad have attracted more and more attention because of their high efficiency and energy-saving features. However, the price of three to five million yuan per unit and the expensive maintenance costs have discouraged many users. [0003] The inventor found in practice that it is feasible in principle to produce a full-hydraulic rock drilling excavator with a hydraulic ...

Problems solved by technology

Chinese patent application CN201010232995.6 discloses a hydraulic rock drilling rig for an excavator, but the hydraulic rock drilling rig is simply connected to the hydraulic excavator without any improvement on the power source of the excavator; the drilling rig must also be equipped with outriggers , the swing angle of the drilling rig is adjusted by the swing cylinder, so the swing angle of the drilling rig is very limited, and the structural design of the whole machine is complicated
