Hole drilling hole position and depth self-adjusting type tunnel blasting hole drilling device

Abstract

The invention discloses a hole drilling hole position and depth self-adjusting type tunnel blasting hole drilling device, which comprises a horizontal base plate, a horizontal bottom plate, a hole drilling device and a jacking mechanism, wherein the hole drilling device is arranged above the horizontal bottom plate and can forwards and backwards move on the horizontal plane; the jacking mechanism pushes the hole drilling device to forwards and backwards move and correspondingly regulates the hole drilling depth of the hole drilling device; the hole drilling device comprises an annular rail, a hole drilling machine frame, two rail support seats and a vertical installing seat; the vertical installing seat is positioned at the back side of the annular rail; a transverse slide moving rail is arranged at the front side of the hole drilling machine frame; a plurality of drilling tool installing seats capable of doing transversely slide moving are arranged on the transverse slide moving rail; the jacking mechanism comprises a jacking plate and a plurality of jacking hydraulic cylinders; and a horizontal slide moving seat is arranged at the bottom of the vertical installing seat. The hole drilling hole position and depth self-adjusting type tunnel blasting hole drilling device has the advantages that the structure is simple; the design is reasonable; the installation and the arrangement are convenient; the use and the operation are simple and convenient; the use effect is good; the hole drilling process of a plurality of blast holes in a blasting surface can be simply, conveniently and fast completed; and the hole drilling hole position and the hole drilling depth can be simply and conveniently regulated.

Description

technical field [0001] The invention relates to a drilling device, in particular to a self-adjusting drilling hole position and depth drilling device for tunnel blasting. 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 aff...
