Blasting drilling device used for tunnel blasting construction

Abstract

The invention discloses a blasting drilling device used for tunnel blasting construction. The blasting drilling device comprises a horizontal pedestal, a circular-ring-shaped guide rail, a drilling machine frame, a vertical installation base and a push plate, wherein the circular-ring-shaped guide rail is located above the front side of the horizontal pedestal, the drilling machine frame is installed on the circular-ring-shaped guide rail and can rotate by 360 degrees on a vertical face along the circular-ring-shaped guide rail, the vertical installation base is located on the rear side of the circular-ring-shaped guide rail, and the push plate is arranged on the rear side of the vertical installation base and is a rectangular plate. The circular-ring-shaped guide rail is arranged in the vertical direction. The drilling machine frame is a long-strip-shaped machine frame. The drilling machine frame and the circular-ring-shaped guide rail are arranged on the same vertical face. A horizontal rotating shaft for driving the drilling machine frame to rotate is installed on the front side of the upper portion of the vertical installation base. A plurality of push rods for horizontally pushing the circular-ring-shaped guide rail forwards are arranged on the front side of the push plate. A plurality of electric drilling tools for drilling blast holes are installed on the front side of the drilling machine frame. The blasting drilling device used for tunnel blasting construction is simple in structure, reasonable in design, convenient to install and arrange, easy and convenient to use and operate, good in using effect and capable of completing the drilling process for drilling the multiple blast holes in a blasting surface easily, conveniently and rapidly.

Description

technical field [0001] The invention relates to a drilling device, in particular to a blasting drilling device for tunnel blasting construction. Background technique [0002] In the process of tunnel excavation, when carrying out blasting excavation, it is necessary to drill multiple blastholes arranged in a circular direction on the blasting surface, and then configure explosives according to the pre-designed blasting parameters and put them into each blasthole. Then detonate again to complete the blasting construction. Nowadays, when blasting is carried out in the process of tunnel excavation, measuring tools are usually used to determine the hole position of each blasthole, and then manually use drilling rigs or drilling equipment to create blastholes one by one on the surrounding rock. Due to the large number of blast holes on the blasting surface, it requires a lot of manpower and material resources, and it takes a long time, which greatly affects the tunnel constructi...
