Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of intelligent charging system of blasting hole in tunnel blasting excavation, in particular to a kind of automatic material distribution and belt feeding mechanism of explosive charge. BACKGROUND

[0002] In the tunnel blasting excavation construction process, the filling of detonating charge and explosive charge is the most important link in the whole construction process, and the charge filling efficiency and filling quality directly affect the progress of blasting excavation and the construction quality of the whole tunnel; Due to the limitation of tunnel excavation environment, the tunnel blasting explosive generally adopts the form of emulsion explosive charge to be filled into the blasting hole on the drilled excavation working face; The detonating charge is generally made into a sausage-like form structure, and an electronic detonator is embedded in the detonating charge. The lead-out wire of the electronic detonator is led out to the outside of the detonating charge and connected with the junction box. The shape of the explosive charge is similar to a complete sausage, and only emulsion explosive is covered in the cylindrical coating. The charge of each blasting hole is to fill a detonating charge into the bottom of the blasting hole, and the lead-out wire of the detonator of the detonating charge is thrown out of the blasting hole to the outside of the blasting hole, so that the junction box connected with the outer end of the lead-out wire of the detonator is arranged on the working face outside the blasting hole. Then, a plurality of explosive charges are sequentially filled to fill the blasting hole with explosive. After the filling of explosive is completed in all blasting holes on the blasting working face, the junction boxes at the outer ends of the lead-out wires of the detonators of the detonating charges are connected to the busbar, and finally, the blasting signal is sent through the busbar to detonate the explosive filled on the working face, thereby realizing the blasting excavation of the tunnel.

[0003] At present, in the tunnel blasting construction, the charge of the blasting hole is filled by manual charging. The operator fills the explosive in high temperature, high humidity and high dust environment. Because the blasting working face is as high as ten meters or more, the high-altitude explosive filling operation has the installation risk of high-altitude operation. In addition, the construction environment is harsh, the explosive filling quality is not high, the labor intensity is too large, and the charging efficiency is low. Therefore, how to develop an intelligent charging system has become an urgent problem to be solved in the construction site.

[0004] With the development of robot technology, intelligent robots are used to replace manual charging on site, which has become a topic that the technical personnel in the field are trying to overcome. However, how to realize the full-automatic charging of the mechanical charging hand at the blasting working face is a primary problem to be solved. Each blasting hole on the working face needs to be filled with a detonating charge and a plurality of explosive charges. The filling amount of explosive charge is large. How to effectively separate the explosive charges collected together in the explosive charge bin and stepwise fill them into the blasting hole to realize full-automatic operation is another difficult problem to be solved by the technical personnel in the field.
