Problems solved by technology

Pneumatic rock drilling equipment is simple in structure and low in cost, but low in efficiency and high in energy consumption
At present, simple hand-held drilling rigs are still widely used in various rock drilling sites, which are not only inefficient, but also labor-intensive and harmful to health.
[0003] JP9-221978A discloses a hydraulic rock drilling rig for an excavator, and specifically discloses the following technical features "it is made up of an excavator (5) and a drilling rig, and the base of the excavator (5) is used as the chassis, and the drilling rig itself has no power, the drilling rig is installed at the bucket position of the excavator (5), but this machine is expensive, complicated to install, and the positioning is not flexible enough, the operation efficiency is low, and it cannot adapt to complex terrain operations

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the drawings and the best embodiments.

[0018] Refer to Figure 1-Figure 2 , The hydraulic rock drilling rig of the excavator consists of excavator A and drilling rig B. The machine uses the base of excavator A as the chassis, and the drilling rig B has no power. The drilling rig B is installed in the bucket position of excavator A; The hydraulic valve group of the feed motor 1, the rock drill head 2, the compensation cylinder 4 and the swing cylinder 7 is connected to the spare oil circuit of the excavator A and the control box C.

[0019] The drilling rig B is composed of a feed motor 1, a rock drill head 2, a propulsion beam 3, a compensation cylinder 4, a drill rod 5, a cylinder seat 6, a swing cylinder 7, a drill leg 8, a tension device 9 and a drill bit 10; The outrigger 8 is installed on the head of the drilling rig B; the swing cylinder 7 is installed on the outrigger 8 of the drilling rig,...

Abstract

The invention relates to a hydraulic rock drilling machine, in particular to a drilling machine arranged on an excavator, relating to engineering machinery. The hydraulic rock drilling machine comprises the excavator (A) and the drilling machine (B), wherein the hydraulic rock drilling machine utilizes a machine base of the excavator (A) as a chassis; the drilling machine (B) without own power isarranged on the bucket position of the excavator (A); and a feed motor (1), a rock drilling machine head (2), a compensating oil cylinder (4) and a hydraulic valve group of an oscillating oil cylinder (7) are connected with a reserved oil line of the excavator (A) and a control box (C). The hydraulic rock drilling machine has the advantages of high efficiency, energy saving, low cost and easy maintenance and is based on a hydraulic excavator platform.

Description

Technical field [0001] The invention relates to an engineering machine, in particular to a drilling rig installed on an excavator. Background technique [0002] Hydraulic rock drilling rigs have been well applied in foreign engineering construction and mining operations due to their high efficiency, energy saving, and good working conditions. Countries such as Sweden and France compared the energy consumption of hydraulic rock drilling equipment and pneumatic rock drilling equipment as early as the late 1970s, and their ratio was 1:3.85; and the cost per meter of blasthole was 1:1.3. In recent years, the statistics and comparative figures used in the railway, hydropower and mining sectors in my country have also confirmed this point. However, currently, pneumatic rock drilling equipment is still widely used in my country. The main reason is that hydraulic rock drilling rigs have complex structure and high technical requirements, and there are no mature products in China. Import...
