Problems solved by technology
Conventional hand-held pneumatic rock drills have simple structure, convenient maintenance, easy operation, and low cost, but they have disadvantages such as low efficiency, high labor intensity, and poor safety, and it is difficult to adapt to the operation requirements of long-term high-intensity continuous work
Although foreign hydraulic rock drilling rigs have a high degree of automation and fast construction speed, they are expensive, have a large amount of over-excavation, and high construction costs. They are not suitable for the current situation of tunnel construction in my country and the construction technology of drilling and blasting.

The invention relates to a track-type four-arm rock drilling jumbo. The conventional hand-held pneumatic excavators have the disadvantages of low efficiency, great labor intensity of workers, poor safety and the like, and cannot meet the operation requirements of long-time high-strength continuous work; and the imported hydraulic drilling jumbos have high automation degree and fast construction speed, but also have high price, great overbreak volume and high construction cost and are not suitable for current tunnel construction situation and the conventional drilling-blasting construction process of China. The track-type four-arm rock drilling jumbo comprises four main machine devices, a track vehicle body platform, a lift platform device, a pumping station part, an operating console device and an electric starting box, and realizes semi-automatic rock drilling construction. The track-type four-arm rock drilling jumbo has the advantages that: the rock drilling jumbo has semi-automaticcontrol and high reliability and realizes remote control of rock drilling construction through the operating console; and the entire rock drilling jumbo can be moved conveniently and is suitable for tunnel drilling-blasting multi-step construction, thereby effectively improving construction conditions, reducing labor intensity, guaranteeing safety operation, quickening construction progress and improving construction quality.
Description
technical field [0001] The invention relates to a crawler-type four-arm rock drilling jumbo. technical background [0002] In the prior art, air-leg pneumatic drills and hand-held pneumatic drills are widely used in tunnel drilling construction. Conventional hand-held pneumatic rock drills have simple structure, convenient maintenance, easy operation, and low cost, but they have disadvantages such as low efficiency, high labor intensity, and poor safety, making it difficult to adapt to long-term high-intensity continuous work. Although foreign hydraulic rock drilling rigs have a high degree of automation and fast construction speed, they are expensive, have a large amount of over-excavation, and high construction costs, and are not suitable for the current situation of tunnel construction in my country and the drilling and blasting construction process. Contents of the invention [0003] The technical problem solved by the present invention is to provide a crawler-type fo...
