Automatic portable rig for tunnel blasting construction

Abstract

The invention discloses an automatic portable rig for tunnel blasting construction. The automatic portable rig comprises a drill stand and an electric drill arranged on the drill stand, wherein the drill stand comprises a drill stand monitoring device, an electric lifting bracket, a horizontal sliding track, a travelling trolley and a base, the electric lifting bracket is distributed in the front side of a wall rock blasting surface and can ascend and descend in the vertical direction; the horizontal sliding track is arranged on the electric lifting bracket; the travelling trolley moves left and right along the horizontal sliding track; the base is arranged on the travelling trolley and can move back and forth on the travelling trolley; the electric drill is arranged on the base; the drill stand monitoring device comprises a controller, a parameter setting unit, a counter, a height sensor, a position sensor I, a position sensor II, a position sensor III and a feeding depth detection unit. The automatic portable rig is reasonable in design, convenient in wiring, simple and convenient in use operation, high in intelligent degree and good in use effect, and can be used for drilling automatically according to the drilled hole amount, drilling path, drilled hole positions and drill hole depth which are designed in advance.

Description

technical field [0001] The invention belongs to the technical field of tunnel blasting construction, and in particular relates to an autonomous mobile drilling machine for tunnel blasting 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. When actually carrying out rock drilling and blasting construction, generally a drilling rig or drilling equipment is used to open multiple blastholes first, and then the explosive package is configured according to the pre-designed blasting parameters and put into each blasthole, and then detonated to complete the blasting process. Blasting construction. Nowadays, when blasting is carried out in the process of tunnel excavation, the hole positions of each blast hole are generally determined one by one by using measuring tools, and then the blast holes are opened one by one in...

AI Technical Summary

Problems solved by technology

Nowadays, when blasting is carried out in the process of tunnel excavation, the hole positions of each blast hole are generally determined one by one by using measuring tools, and then the blast holes 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 pre-fabricated explosive packs are manually put into each blasthole, which requires a large amount of manpower and material resources, and takes a long time, which affects the tunnel construction period.

To sum up, there is a lack of an autonomous mobile drilling rig for tunnel blasting construction with reasonable structural design, convenient installation and layout, easy operation and good use effect, which can drill holes according to the pre-designed number of drilling holes, drilling routes and holes. The hole position and hole depth are automatically drilled, which greatly improves the efficiency of drilling construction and saves construction time
