Description

Technical Field

[0001] The present invention belongs to the technical field related to tunnel construction equipment, and more specifically, relates to a fully hydraulic rock drilling platform. Background Art

[0002] A rock drill, also known as a drilling rig, is a type of rock drilling equipment used in tunneling and underground construction using the drill-and-blast method. It can move and support multiple rock drills for simultaneous drilling operations. The working mechanism primarily consists of a thruster, a drill boom, a slewing mechanism, and a translation mechanism. Rock drill rigs can be categorized as tunneling, mining, anchoring, and surface drilling. They are categorized by their travel mechanism into rail-wheel, tire-type, and crawler-type models. They can also be categorized by the number of rock drills mounted, into single-rig, dual-rig, and multi-rig models.

[0003] At present, the three-arm drilling rigs used in tunnel construction operations in China are mainly three-arm drilling rigs produced abroad and three-arm drilling rigs imitated from foreign models. Their structure and working principle are basically the same, with the two side arms on the top and the middle arm on the bottom, and the two side arms are used to complete the drilling of holes on the top and both sides of the tunnel.

[0004] However, further research shows that the existing technology still has the following defects or deficiencies: for the drilling rig with the above-mentioned structural form, the middle arm can only partially complete the drilling of the lower part of the blastholes, and the number of blastholes is very small, accounting for only one-tenth of the entire section, so the utilization rate of the middle arm is very low; in addition, several tens of percent of the workload of the entire section has to be completed by the arms on both sides, so the utilization rate of the three arms can only reach about 75%. To complete all the drilling work, the drilling time needs to be extended by one-third, resulting in the need to improve the utilization rate and work efficiency of the entire vehicle. Summary of the Invention

[0005] In response to the above-mentioned defects or improvement needs of the prior art, the purpose of the present invention is to provide a new type of fully hydraulic rock drilling platform, in which the structural composition of the entire device and the setting of some key modules are redesigned, especially targeted improvements are made in combination with the spatial layout and working mechanism of the three drill arms.
