Problems solved by technology

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 charging trolley fails during the charging process, it cannot guarantee that the emulsion explosive will be detonated within 8 hours. If it is installed and detonated within an hour, it will seriously affect the safety of production

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] see figure 1 , Figure 2 and image 3 , an emulsion explosive charging trolley, including the hydraulic control system of the working arm and the emulsion explosive charging system. The pressure of the entire working system can be adjusted through the overflow valve 3, and the proportional valve group is installed on the frame. Its main function is Hydraulic control or manual operation of the working boom and flow distribution and pressure adjustment of the hydraulic oil; the control valve group 6 is installed on the working basket, and its function is mainly to use the pilot oil to control the action of the proportional valve group 5 to achieve the operation of the working boom . Therefore, when the operator needs to perform various actions on the working arm on the ground, the proportional valve group 5 can be manipulated to change the oil cyl...

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...
