An underground granular explosive charging service vehicle

Abstract

The invention discloses an underground granular explosive loading service cart, and belongs to the technical field of minelite filling. The underground granular explosive loading service cart comprises a front frame chassis and a rear frame chassis. An engine tandem pump assembly, a front drive wheel bridge, an electrical control system, an operating console, a hydraulic oil tank and a fuel tank are fixed to the front frame chassis. A rear driving wheel bridge, a work arm, an explosive loading system, an air compressor and a pneumatic system are arranged on the rear frame chassis. The front frame chassis is connected with the rear frame chassis through a central hinge device and a steering oil cylinder. The explosive loading system is connected with the air compressor and an air duct of the pneumatic system. A front frame and a rear frame are in a central hinged mode, and a hydrostatic drive technology, a double-motor four-wheel drive technology and a hydraulic steering chassis walking technology are adopted, so that the underground granular explosive loading service cart is high in mechanical performance and grade ability, good in cross-country performance, free of potential safety hazards and low in manual labor intensity and can be suitable for poor working conditions of underground mines, tunnels, underground building engineering and the like and overcome the defects in the prior art, and explosives can be conveniently and quickly loaded.

Description

technical field [0001] The invention belongs to the technical field of mining explosive filling, and relates to an underground granular explosive charging service vehicle. Background technique [0002] In underground construction such as mining and tunnels, blasting operations are often required. Most of the blasting operations are drilled by rock drills to a certain depth, and then filled with explosives. , the efficiency of manual filling is low, prolonging the cycle time of mining or excavation operations, and the quality of charge is poor, the blasting effect cannot be effectively guaranteed, prolonging the cycle time of mining or excavation operations, and the quality of charge is poor, the blasting effect cannot be effectively guaranteed ensure. In addition, the labor intensity of the workers who charge the powder is high, and they spend a long time in the empty mining area, which poses a great potential safety hazard. [0003] With the continuous development of scie...
