Description

Technical Field

[0001] The invention relates to an intelligent charging system for blasting holes in tunnel blasting, and in particular to an intelligent charging system based on an arch trolley for blasting holes on rock walls in tunnel blasting. Background Art

[0002] Mining blasting is the main construction method for tunnel excavation. During the tunnel blasting construction process, a series of dense blasting holes are usually drilled on the rock wall of the face, and then emulsion explosives are filled into each blasting hole. Finally, the construction workers stay away from the blasting face and realize tunnel excavation by detonation. Due to the limitations of construction conditions in the tunnel, tunnel blasting generally uses emulsion explosive rolls as explosive raw materials to fill the blasting holes. Emulsion explosive rolls are divided into two types: detonating explosive rolls and explosive rolls. Electronic detonators are pre-buried in the explosive rolls. The lead-out wires of the electronic detonators are connected to the detonating busbar after being thrown out of the blasting hole. In a blasting hole, generally one explosive roll is filled first, and then several explosive rolls are filled. The detonators first detonate the explosive rolls and then the explosive rolls, thereby achieving blasting of the rock mass. Therefore, the loading of explosive packages and explosive packages is the most important link in the entire construction process. The filling efficiency and quality of the packages will directly affect the progress of blasting excavation and the construction quality of the entire tunnel.

[0003] At present, in tunnel blasting construction, the drilling of blasting holes on the face has been mechanized, but the charging of blasting holes is still carried out by manual charging. Operators perform high-altitude charging operations in a high-temperature, high-humidity and high-dust environment. Since some blasting faces are as high as ten meters or more, on-site operators generally use arch trolleys to achieve aerial operations. High-intensity explosives filling operations at high altitudes have safety hazards, coupled with the harsh construction environment conditions, there are generally defects such as low explosives filling quality, excessive labor intensity and low charging efficiency. How to develop an intelligent and fully automatic charging system has become a problem that urgently needs to be solved at the construction site.

[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 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 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 holes, 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 and orderly separate the explosive cords gathered in the explosive cord silo, and step-by-step fill them into each blasting hole to achieve fully automated operation is another difficult problem that technical personnel in the field need to solve.
