Tunnel blasting excavation construction multi-functional drilling and blasting trolley

Abstract

The invention discloses a tunnel blasting excavation construction multi-functional drilling and blasting trolley. The tunnel blasting excavation construction multi-functional drilling and blasting trolley comprises a horizontal chassis, a plurality of round horizontal sliding boards mounted on the horizontal chassis from left to right, a plurality of round horizontal rotating plates respectively mounted on the plurality of round horizontal sliding boards, and a plurality of electric lifting support frames fixedly mounted on the plurality of round horizontal rotating plates respectively. The round horizontal rotating plates are mounted on the horizontal chassis through rotating shafts. The plurality of electric lifting support frames are arranged from left to right and respectively mounted with a drilling and blasting mechanism. A plurality of moving wheels and a support hydraulic cylinder for supporting and ejecting the horizontal chassis during the rotation to the left and the right are mounted at the bottom of the horizontal chassis. The tunnel blasting excavation construction multi-functional drilling and blasting trolley is simple in structure, reasonable in design, easy to use and operate, good in use effect, flexible in assembly mode and capable of easily and quickly completing a process of drilling of multiple blast holes and explosive feeding.

Description

technical field [0001] The invention belongs to the technical field of tunnel blasting and excavation construction, and in particular relates to a multifunctional rock drilling and blasting vehicle for tunnel blasting and excavation construction. Background technique [0002] In the process of tunnel excavation, most of them need to be blasted first, and rock drilling and blasting construction is an important tunnel blasting construction method. In actual rock drilling and blasting construction, it is often necessary to open multiple blasting holes on the blasting surface, and then configure the explosive package according to the pre-designed blasting parameters and put them into each blasting hole, and then detonate to complete the blasting construction. Nowadays, when blasting is carried out in the process of tunnel excavation, the hole position of each blasthole is generally determined by measuring tools, and then the blastholes are opened one by one in the surrounding ro...

AI Technical Summary

Problems solved by technology

Nowadays, when blasting is carried out in the process of tunnel excavation, the hole position of each blasthole is generally determined by measuring tools, and then the blastholes are opened one by one in the surrounding rock by manual drilling rigs or drilling equipment; And after the opening of the blastholes is completed, the prefabricated explosives are manually put into each blasthole, which requires a lot of manpower and material resources, and takes a long time, which affects the tunnel construction period.
