Problems solved by technology

However, due to the large angle of the blasting hole, which is more than 50° to the axis of the roadway, it is difficult for traditional blasting sticks to push the explosive cartridges required for blasting into place. The charge is discontinuous, and there are explosions and rejections during the blasting process.

Abstract

The invention discloses a hydraulic loading device for loading explosive in a large-angle deep hole. The hydraulic loading device comprises a loading part which is arranged in an explosive hole, and a delivering part for sending an explosive package to the explosive hole, wherein the loading part comprises tapered rubber rings; pressure cavities are arranged in the tapered rubber rings; the pressure cavities are communicated with a high pressure oil pipe; pressure oil is filled in the pressure cavities through the high pressure oil pipe to enable the tapered rubber rings to be expanded and deformed; the tapered rubber rings expand and squeeze the inner wall of the explosive hole to enable the loading part to be embedded and fixed in the explosive hole; and the explosive package in the explosive hole is fixedly connected with the loading part to realize the explosive loading. The hydraulic loading device is simple in structure; a large quantity of the explosive can be loaded at one time; discontinuous explosive loading or untight contact of the explosive package are avoided; and the explosive package is effectively prevented from falling off, and an explosive effect of the large-elevation deep hole is ensured. And moreover, by an explosive lifting and unloading method through static and dynamic double pulleys, the loading cost is saved, and the fast loading of the explosive is realized.

Description

technical field [0001] The invention relates to a large-angle deep-hole charge hydraulic installer. Background technique [0002] With the continuous expansion of the construction scale of geotechnical engineering such as water conservancy and hydropower, road tunnels and underground resource mining, various engineering problems are becoming more and more serious. Among them, during the excavation of various chambers and roadways, the cutter head of the roadheader or TBM shield machine is stuck due to the change of lithology, and the rock burst (or rock burst) is caused by the accumulation of energy due to the deformation of the overlying hard rock layer, Dynamic disasters such as large-area roof instability and collapse are common, seriously restricting the smooth progress of geotechnical engineering and threatening the safety of workers. [0003] Blasting is often used to soften the hard rock formations encountered in tunneling and hydropower chamber excavation projects. ...
