Drilling-splitting trolley

Abstract

The invention provides a drilling-splitting trolley which comprises a chassis, a crane arm mechanism, a drilling-splitting mechanism, a hydraulic system and an electric control system, wherein a trolley frame is arranged on the chassis; a crawler is arranged at the bottom of the trolley frame; a supporting leg is arranged at the front part of the trolley frame; the crane arm mechanism comprises arotating platform, an telescopic arm and a pitch oil cylinder; the telescopic arm is connected with the rotating platform; the pitch oil cylinder is arranged between the rotating platform and the telescopic arm; through the extension and retraction of the pitch oil cylinder, the telescopic arm can be driven to move up and down; the rotating platform is used for driving the telescopic arm to swingleft and right; the drilling-splitting mechanism comprises a rotating component, a rock drilling machine part and a splitting machine part; the rock drilling machine part and the splitting machine part are integrated as well as connected with the telescopic arm through the rotating component; the hydraulic system is used for providing power for the drilling-splitting mechanism; and the electric control system is used for controlling the running of the drilling-splitting mechanism. According to the drilling-splitting trolley, the integrated design of the rock drilling machine part and the splitting machine part is adopted, so that the combination of actions can be reduced during the constriction operation of the drilling-splitting trolley, the operation can be simplified, and the drilling-splitting construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a drilling and splitting trolley. Background technique [0002] With the rapid development of high-speed railway and expressway traffic construction, the development of tunnel mechanical excavation construction equipment will be greatly promoted. The traditional long tunnel construction often uses the drill and blast method for excavation, and the drill and blast method is used in the blasting construction process. There are many safety hazards, such as noise, dust, flying rocks, smoke, especially the unstable impact of blasting on the surrounding rock of the tunnel, which may easily cause safety hazards such as landslides. [0003] In view of the above hidden dangers, it is necessary to invent a drilling and splitting jumbo with the integration of drilling and splitting mechanism and splitting mechanism, and replace the drilling and blasting method with the...

AI Technical Summary

Problems solved by technology

However, most of the existing drilling and splitting trolleys separate the drilling and splitting mechanism and the splitting mechanism on two independent booms. During the splitting construction operation, there are many action combinations, cumbersome operations and greatly reduce the Drilling and chopping construction efficiency

[0004] In summary, there is an urgent need for a drilling and splitting jumbo to solve the problems of many action combinations, cumbersome operations and low drilling and splitting construction efficiency in the prior art
