Abstract

The invention discloses a drilling and punching combined type rock breaking device for roadway tunneling. The drilling and punching combined type rock breaking device comprises a support. A drilling hydraulic cylinder is arranged on the support, and the end of a piston rod of the drilling hydraulic cylinder is fixedly connected with the workbench. A drilling assembly and an impact assembly are arranged on the workbench. The drilling assembly comprises a drilling guide rail, two drill bit assemblies are arranged on the drilling guide rail, and each drill bit assembly comprises a drill rod; the impact assembly comprises a transverse guide rail which is in sliding fit with an impact guide rail. Two groups of punch assemblies are arranged on the impact guide rail, and each punch assembly comprises an impact rod; the central axis of the drill rod, the central axis of the impact rod and the central axis of the piston rod of the drilling hydraulic cylinder are parallel; the sliding direction of the impact guide rail along the transverse guide rail is consistent with the axis direction of the impact rod; the plane where the central axes of the two drill rods are located is parallel to the plane where the central axes of the two impact rods are located. Through the arrangement of the drill bit assembly and the punch assembly, the purpose of crushing local rocks is achieved through expansion connection of local cracks of the rocks.

Description

technical field [0001] The invention belongs to the technical field of rock-breaking equipment, and in particular relates to a drilling-punching compound rock-breaking device for roadway excavation. Background technique [0002] Hard rock is often encountered in the process of roadway excavation, and the breaking of hard rock becomes a difficult problem in the process of roadway excavation. The breaking efficiency of hard rock directly affects the speed of roadway excavation. [0003] During roadway excavation, traditional rock breaking methods mainly include drilling and blasting and mechanical rock breaking. [0004] The drill and blast method is to excavate the rock by drilling, charging, and finally blasting the rock. This rock-breaking method greatly disturbs the surrounding rocks. If the drilling and blasting method is used in one place, the disturbance generated after the blasting may affect the safety of the entire roadway. Therefore, the safety of this method is r...
