Abstract

The invention relates to full-hydraulic down-the-hole rock drilling equipment, in particular to an anchoring drilling machine based on the working mode of double-pump complementation automatic merging, comprising a sliding frame body, a pumping station and an operating board; wherein, the pumping station comprises a main pump and a jack-head pump, the operating board includes a main pump pilot overflow valve, a jack-head pump pilot overflow valve, a rotary motor pilot overflow valve and a high pressure stop valve; and the sliding frame body, the pumping station and the operating board are connected by hydraulic pipelines. The invention has the advantages of thoroughly solving the problem that propulsion is affected by rotation caused by a single pump structure, obviously reducing the energy consumption, improving the working efficiency, effectively preventing the waste of storage flow rate, protecting the investment, saving resources and greatly prolonging the service life of the equipment.

Description

technical field [0001] The invention relates to fully hydraulic down-the-hole rock drilling equipment, in particular to an anchor drilling rig based on a double-pump complementary automatic confluence working mode. Background technique [0002] Anchor drilling rigs are mainly used in slope anchor cable reinforcement projects in the construction of hydropower, roads, bridges, railways, etc., and can also be used in the construction of 100mm-220mm blast holes in various blasting operations. The applicable rock hardness is: 6<F<18 , The vertical drilling depth can reach 220M. Different formations, wind pressure, drilling method, hole forming angle, etc. may affect the drilling depth. [0003] In anchor cable reinforcement engineering, the characteristics of anchor cable hole formation can be simply summarized as follows: high difficulty, strict requirements, large diameter, and deep depth. Due to the complex topography of the weak rock stratum and sliding surface, it is...
