Abstract

The invention relates to an emulsification detonator charging trolley, including a working main arm hydraulic pressure control system and an emulsification detonator charging system, wherein the working main arm hydraulic pressure control system includes a hydraulic pressure gear pump, a scale valve set, an operation valve set, a safety valve and a hydraulic pressure meter. The hydraulic pressure gear pump builds a pressure oul feeding hydraulic pressure system; the scale valve set is arranged on the frame which hydraulically or manually operates the working main arm and performs the flux distribution and pressure adjustment to the hydraulic pressure oil; the operation valve set is arranged on the working nacelle which mainly uses the leading oil pressure control scale valve to operate the working main arm. The grain detonator charging trolley is changed into the emulsification detonator charging trolley, which solves the idle problem of the NT30 / NBB 150 charging trolley with low cost, to be used again.

Description

【Technical field】

[0001] The invention belongs to the field of mining machinery and relates to an emulsion explosive charging trolley used for mining underground in mines. 【Background technique】

[0002] The existing NT30 / NBB150 granular explosive charging trolley has a long service life and high failure rate. Whenever explosives are loaded in the underground stope, it is often necessary to drive two NT30 / NBB150 granular explosive charging trolleys to the stope, one charge, and another spare to ensure that the explosives can be loaded and detonated within the specified time. Since emulsion explosives must be used in the mechanized mining of medium and deep holes in the underground panel of the mine, the NT30 / NBB150 granular explosive charging trolley must be stopped and idled. According to the national blasting regulations: emulsion explosives must be detonated within 8 hours, otherwise a natural detonation safety accident may occur. If the existing emulsion explosive charg...
