Peripheral hole joint cutting equipment for improving smooth blasting energy gathering effect

Abstract

The invention discloses peripheral hole joint cutting equipment for improving the smooth blasting energy gathering effect. The peripheral hole joint cutting equipment comprises a guide rod system, a cutterhead system and an ash extraction system, and further comprises a voltage supply interface and a master control switch, wherein, the master control switch comprises a first button and a second button; and the first button can be used for power start of the equipment. According to the equipment, the first button can start power of equipment, the second button can adjust the length of an electric telescopic guide rod, and the first button is pressed to start a hydraulic transmission system, so that high-pressure liquid flow flows out of a hollow rod on the left side in a main guide rod system, passes through a rotating shaft and drives a diamond cutterhead to rotate under the action of a hydraulic gear motor.

Description

technical field [0001] The invention relates to the technical field of smooth blasting, in particular to a peripheral eye slit device for improving the energy gathering effect of smooth blasting. Background technique [0002] Smooth surface blasting can make the blasting cracks develop along the expected direction, so that the cross-sectional profile of the blasted roadway meets the design requirements. The current smooth surface blasting has the following problems: ①The surrounding holes are too densely distributed, and the drilling operation takes a long time; ②There are holes in the blast hole The position of the drug coil is very likely to cause cracks in the surrounding rock or the blasting energy of the drug coil in the surrounding holes is concentrated, destroying the overall integrity of the surrounding rock and affecting the stability of the surrounding rock; , the processing is difficult, labor-intensive and time-consuming; ④ blasting energy cannot be fully utilize...

[0002] Smooth surface blasting can make the blasting cracks develop along the expected direction, so that the cross-sectional profile of the blasted roadway meets the design requirements. The current smooth surface blasting has the following problems: ①The surrounding holes are too densely distributed, and the drilling operation takes a long time; ②There are holes in the blast hole The position of the drug coil is very likely to cause cracks in the surrounding rock or the blasting energy of the drug coil in the surrounding holes is concentrated, destroying the overall integrity of the surrounding rock and affecting the stability of the surrounding rock; , the processing is difficult, labor-intensive and time-consuming; ④The blasting energy cannot be fully utilized, and the utilization rate of explosives is low

⑤ A large amount of toxic and harmful gas and dust are produced during blasting, polluting the working environment;

[0003] In the existing smooth blasting conditions, when the blasting energy-concentrating tube is filled with emulsion explosives, manual hand-held filling guns are prone to the disadvantage of uneven filling of the blasting energy-concentrating tube; The charge time is long, the explosion energy cannot be effectively exerted, the hole position deviation still exists, it is difficult to form an ideal section, the disturbance to the surrounding rock is still strong, and the problem of overbreak and underbreak has not been effectively improved

The outstanding advantage of using high-pressure water jet grooving is that the grooving quality is good, but the grooving device is relatively complicated, heavy, consumes a lot of energy, and is expensive
