Problems solved by technology

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 blasting holes on the blasting surface, it takes a lot of manpower and material resources, and it takes a long time, which greatly affects the tunnel construction period

Abstract

The invention belongs to the technical field of blasting, and discloses a blasting drilling device conveniently drilling a plurality of blast holes and for blasting construction. The blasting drillingdevice includes a base and a longitudinal mounting seat, wherein the longitudinal mounting seat transversely arranged on the base in a displacement mode, universal wheels with brakes are arranged onthe lower part of the base, a first drilling machine is arranged on the transverse side of the longitudinal mounting seat, a mounting end is arranged on the other side of the longitudinal mounting seat, and a second rod group and a first rod group are sequentially arranged at the mounting end; first rods are evenly provided with a plurality of first mounting holes in the longitudinal directions ofthe first rods correspondingly; second rods are evenly provided with a plurality of second mounting holes in the longitudinal directions of the second rods correspondingly; the first rod group and the second rod group are distributed circumferentially in a staggered mode; and the lengths of the first rods are less than lengths of the second rods and are equal to the radius of the first drilling machine. According to the blasting drilling device for blasting construction, drilling operation can be simultaneously conducted on the inner part and the outer part of a blasting construction position, and thus multiple blast holes can be simultaneously drilled through the blasting drilling machine for blasting construction.

Description

technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a blasting drilling device for blasting construction which is convenient for drilling a plurality of blasting holes. Background technique [0002] During the blasting construction, it is necessary to drill multiple blast holes on the blasting surface first, then configure the explosive packs according to the pre-designed blasting parameters and put them into each blast hole, and then detonate 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 ...
