The invention relates to a deep hole charging air gap device. The deep hole charging air gap device comprises a supporting frame and an operating mechanism. The supporting frame comprises a fixing rod, and at least three support rods are hinged to the bottom of the outer wall of the fixing rod. Every two adjacent support rods are connected through flexible connecting objects. The outer wall of each support rod is connected with the outer wall of the fixing rod through a spring. The top of each support rod is provided with a pull ring. The operating mechanism comprises an operating rod and a sleeve. The operating rod is sleeved with the sleeve. Pull rods are hinged to the bottom of the operating rod and are further arranged at intervals in the circumferential direction of the operating rod.The end, far away from the hinged point, of each pull rod is provided with a hook. The pull rods and the support rods are in one-to-one correspondence. The supporting frame is hung onto the hooks ofthe pull rods through the corresponding pull rings. The deep hole charging air gap device is low in cost and convenient to operate, the charging efficiency can be improved and blasting cost is reduced.
Description
technical field [0001] The invention relates to a deep-hole charging air spacer. 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, improv...
