Auxiliary charging device for on-site mixed emulsified explosive charging vehicle

Abstract

The invention discloses an auxiliary explosive loading device for an on-site mixing emulsion explosive loading truck. The auxiliary explosive loading device comprises an auxiliary explosive loading device body, supports and a lifting mechanism, wherein the auxiliary explosive loading device body comprises a metal ring and an anti-static rubber layer which wraps the metal ring; the multiple supports are arranged around the auxiliary explosive loading device body and are separately connected with the auxiliary explosive loading device body; and the lifting mechanism is arranged on the auxiliary explosive loading device body. By adopting the auxiliary explosive loading device for the on-site mixing emulsion explosive loading truck, an anti-static effect can be well realized; an electric detonator is prevented from being interfered by static electricity and the like, so that accidents are prevented; besides, through the design of the auxiliary explosive loading device body, the hole wall of a blasting hole is well protected, and the phenomenon of hole blogging of the blasting hole caused by the fact that movable stones fall into the blasting hole can be avoided; the labor intensity of operation personnel is lowered; and the working efficiency is improved.

Description

technical field [0001] The invention relates to an auxiliary device for filling emulsion explosives into a blast hole, in particular to an auxiliary charging device for an on-site mixed emulsified explosive charging vehicle, which belongs to the technical field of auxiliary mining equipment in the mining industry. Background technique [0002] In recent years, with the continuous advancement of mechanical processing technology, more and more mechanical mining equipment has been applied to mine mining. As the main link of mine mining, drilling and blasting operations have played an important role in mine mining quality, mining progress and mining costs. How to improve the quality of drilling and blasting operations and speed up drilling and blasting operations is a problem faced by more and more mining managers and engineering technicians. On-site mixed explosives charging vehicles save money for mining in the charging process of blasting operations. A lot of time and cost, i...

AI Technical Summary

Problems solved by technology

[0004] Due to the existence of a lot of gravel and pumice at the blasting site and the uneven working surface of the blasting area, during the charging process, the holes drilled by the drilling equipment will be damaged by the mixed explosives on the working surface and in the holes due to the on-site mixed explosives and the feeding tube of the charging vehicle. Moving back and forth and stretching up and down, as well as other factors such as the walking of the operator, some gravel, pumice or loose stones on the wall of the blast hole will fall into the blast hole and cause the blast hole to get stuck, which will cause the charge speed to increase. The reduction will affect the charge efficiency, and more seriously, it will lead to discontinuous charge in the blast hole, residual charge or blind shot, etc.

In the Chinese patent No. 201120181857.X utility model patent "inflatable blasthole shield", the Chinese patent No. 201420400577.7 utility model patent "a protection device for protecting the broken section of the blasthole hole", the Chinese patent No. 201420199116.8 The utility model patent "A Supporting Beam Blasting Blasting Hole Protection Structure" introduced some devices for protecting the blasthole, but these only solved the protection of the blasthole, and still could not avoid the hole jamming phenomenon when the blasthole was charged. In China patent number 201210157465.9 the invention patent "Multifunctional Emulsion Explosive Vehicle", the Chinese patent number 201310007706.6 the invention patent "A Multi-functional Field Mixed Explosive Vehicle", the Chinese patent application number 201410197391.0 the invention patent application "elevated On-Site Mixed Granular Ammonium Fuel Explosive Vehicle" introduced the structure, structure and function of the new mixed explosive charging vehicle respectively. At present, there is no one that can meet the charging requirements of the on-site mixed explosive charging vehicle, and can quickly Good protection of the installations and equipment of the blastholes, this is a problem that needs to be solved
