Abstract

The invention relates to a blasting engineering air spacing device. The blasting engineering air spacing device comprises an operating rod and a supporting frame. The operating rod is provided with an operating rod connecting rod formed in the axial direction of the operating rod. The supporting frame comprises a fixing rod. The fixing rod is provided with a fixing rod connecting hole formed in the axial direction of the fixing rod. The top of the outer wall of the fixing rod is provided with at least two hinged fulcrum rods. Every two adjacent fulcrum rods are connected through a flexible connector. The outer wall of each fulcrum rod is connected with the outer wall of the fixing rod through a spring. The lower end of each fulcrum rod is fixedly connected with a connecting rope. The top of the fixing rod is in threaded connection with the bottom of the operating rod. The connecting ropes sequentially penetrate through the fixing rod connecting hole and the operating rod connecting rod from the bottom of the fixing rod and then are fixedly arranged on the top of the operating rod, and therefore the springs are in a compressed state.

Description

technical field [0001] The invention relates to an air spacer for blasting engineering. Background technique [0002] Drilling and blasting is a common technology for stone excavation, and it is widely used in water conservancy and hydropower, mining, transportation and other fields. The traditional continuous columnar charge has the disadvantages of large unit consumption, high detonation initial pressure, and excessive crushing of rocks, which makes the effective utilization rate of energy of explosives low, and is prone to produce large pieces and roots, causing blasting vibration hazards and many other problems. The air space charge technology can reduce the initial peak pressure of the explosive on the rock around the blasthole, and make the explosion pressure in the hole more uniformly distributed along the axial direction of the blasthole, thereby reducing or avoiding excessive crushing of the surrounding rock near the blasthole and expanding the fracture Area range,...
