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 conveying and feeding mechanism for explosive rolls in the intelligent charging system and a working method thereof. 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, with electronic detonators pre-buried in the detonating rolls. The lead wires of the electronic detonators are led out of the detonating rolls and connected to the junction box. The shape of the explosive charge is similar to a complete sausage. , only emulsion explosive is coated in the cylindrical coating; 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; 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 achieve blasting excavation.

[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 handlers at the blasting face is a primary problem that needs to be solved, especially the automatic step-by-step flow supply of explosive rolls. Since the explosive rolls are accompanied by detonator lead wires and junction boxes, how to complete the loading of the explosive rolls at one time and smoothly throw the lead wires out of the blasting hole so that the junction boxes of each explosive roll can also be smoothly set on the blasting face, creating convenient conditions for the later connection of each junction box with the detonation bus, has become a difficult problem that technical personnel in the field need to overcome. Summary of the invention

[0005] The present invention provides an automatic conveying and feeding mechanism and method for explosive rolls in an intelligent charging system, which realizes automatic step-by-step streamlined feeding of explosive rolls and solves the technical problem of how to complete the loading of explosive rolls in one go and smoothly throw the lead-out wire out of the blasting hole.

[0006] The present invention solves the above technical problems through the following technical solutions: The overall concept of the present invention is as follows: a box-type storage silo for explosive rolls is arranged at the blasting tunnel face, so that it undertakes the task of providing explosive rolls for all blasting holes on the blasting tunnel face, and cooperates with a charging manipulator to automatically complete the supply and charging of explosive rolls; the silo for the box-type explosive rolls adopts an annular closed chain structure, the annular closed chain adopts a serpentine arrangement, cantilever cartridges and coil sleeves are arranged at intervals on the annular closed chain, the explosive rolls are inserted into the cantilever cartridges, and the leads and junction boxes connected to the explosive rolls are inserted into adjacent coil sleeves, and the annular closed chain is controlled by a servo motor to step-by-step convey, so that the explosive rolls in the silo are conveyed to the charging position in sequence; the charging position is arranged in the box-type At the upper left corner of the explosive coil silo, while the manipulator is taking out the explosive coil and transferring it to be loaded into the blasting hole, the I-shaped wheel reel rack on the adjacent coil sleeve is in a rotating wire-releasing working state. When the filling work of the explosive package is completed, the annular closed chain rotates step by step, and the I-shaped wheel reel rack connected to the outer end of the lead-out wire of the explosive coil loaded into the blasting hole automatically bounces off the explosive coil silo. At the same time, the annular closed chain transfers the second group of explosive coils that follow, as well as the lead-out wires and wiring boxes connected thereto, to the explosive coil retrieval station, waiting for the second time of the manipulator to take the explosives. This cycle realizes the automatic supply of explosive coils in the entire explosive coil silo and the cooperation of the manipulator, thereby completing the automatic loading of explosive coils on the entire blasting surface.

On the annular closed chain, the cantilever cartridge and the cantilever tube are alternately arranged at intervals; the outer end of the cantilever cartridge passes through the serpentine through hole and is cantilevered on the front side of the front vertical plate, and a detonating cord is movably inserted in the cantilever cartridge, and the I-shaped wheel reel frame on which the detonating cord of the detonating cord is wound is movably inserted on the cantilever tube, and the upper gear wire disc of the I-shaped wheel reel frame is movably connected between the two limit steps; a notch is provided at the upper left corner of the front vertical plate.

[0008] A piston is movably arranged in the inner cavity of the cantilever tube, a pair of long through holes are arranged on the outer side wall of the cantilever tube, a pair of piston-driven cantilever rods are arranged on the piston, the piston-driven cantilever rods are arranged on the outer side of the cantilever tube after passing through the long through holes, a tension spring fixing pin is arranged on the outer end of the cantilever tube, a tension spring is connected between the tension spring fixing pin and the piston, and the tension spring is arranged in the tube cavity of the cantilever tube; the lower gear wire disc of the I-shaped wheel reel frame is abutted against the two piston-driven cantilever rods, and the upper gear wire disc of the I-shaped wheel reel frame is limited by the front side vertical plate and compressed backwards, and then arranged in the detonator roll storage box, and the tension spring is in a stretched state.

[0009] An inclined chute of the I-wheel reel rack is arranged at the lower left side of the gap, and a pop-up falling baffle of the I-wheel reel rack is arranged on the front side vertical plate on the lower right side of the gap; a long strip slit groove is arranged on the wall of the cantilever cartridge, and a limiting semi-ring is arranged in the middle of the long strip slit groove, and the outer port of the cantilever cartridge is trumpet-shaped.
