Description

Technical Field

[0001] The invention relates to an intelligent charging system for a blasting hole in tunnel blasting excavation, and in particular to an automatic material dividing and feeding mechanism for explosive rolls in the intelligent charging system and a working method. Background Art

[0002] During the tunnel blasting and excavation construction process, the loading of detonating charges and explosive charges is the most important link in the entire construction process. The filling efficiency and quality of the charges directly affect the progress of blasting and excavation and the construction quality of the entire tunnel. Due to the limitations of the tunnel excavation environment, tunnel blasting explosives are generally loaded into the blasting holes on the drilled excavation working face in the form of emulsion explosive rolls. Detonating charges are generally made into a sausage-like structure, in which electronic detonators are pre-buried. The lead wires of the electronic detonators are led out of the detonating charges and connected to the junction box. The shape of the explosive charge is similar to a complete sausage. The cylindrical coating is only coated with emulsion explosive; each blasting hole is charged by first loading a detonator roll into the bottom of the blasting hole, and throwing the detonator lead wire of the detonator roll out of the blasting hole along the blasting hole, so that the junction box connected to the outer end of the detonator lead wire is set on the working surface outside the blasting hole, and then, a number of explosive rolls are loaded in sequence to fill the blasting hole with explosives; after all the blasting holes on the blasting working surface are charged, the junction boxes at the outer ends of the detonator lead wires of each detonator roll are connected to the busbar, and finally, a detonation electrical signal is sent through the busbar, thereby detonating the explosives loaded on the working face to realize blasting excavation of the tunnel.

[0003] At present, in tunnel blasting construction, the charging of blasting holes is carried out by manual charging methods. Operators perform high-intensity explosives filling operations at high altitudes in a high temperature, high humidity and high dust environment. Since the blasting face is as high as ten meters or more, there are hidden dangers of installation at high altitudes. In addition, due to the poor construction environment conditions, there are generally defects such as low quality of explosives filling, excessive labor intensity and low charging efficiency. How to develop an intelligent charging system has become an urgent problem that needs to be solved at construction sites.

[0004] With the development of robot technology, the use of intelligent robots to replace manual on-site charging has become a topic that technical personnel in the field are working hard to overcome. However, how to realize the fully automatic charging supply of mechanical charge hands at the blasting face is a primary problem that needs to be solved. Each blasting hole on the face needs to be filled with a detonating cord and several explosive cords. The automatic step-by-step flow-through supply of detonating cords is difficult. Since the detonating cords are accompanied by detonator lead wires and junction boxes, how to complete the loading of the detonating cords at one time, and smoothly throw the lead wires out of the blasting hole, so that the junction boxes of each detonating cord can also be smoothly set on the blasting face, and create convenient conditions for the connection of each junction box with the detonation busbar in the later stage, has become a difficult problem that technical personnel in the field need to overcome. The filling amount of explosive cords is large. How to efficiently separate the explosive cords gathered together in the explosive cord silo and step-by-step fill them into the blasting hole to achieve fully automated operation is another difficult problem that technical personnel in the field need to solve.
