Auxiliary device for blast hole charging in blasting construction

Abstract

The invention discloses an auxiliary device for charging a blast hole with an explosive during detonating construction. The auxiliary device comprises a load bearing surface and a power supply box, wherein the load bearing surface is arranged at one side of the top surface of a base, and the power supply box is arranged at the other side of the top surface of the base; a roller is arranged on the side surface of the power supply box, a compound wire is wound on the roller, and an explosive charging barrel is connected at one end of the compound wire; and wheels are mounted on the bottom side surface of the base, and a synchronous motor is mounted in the power supply box. According to the auxiliary device for charging the blast hole with the explosive during detonating construction, the compound wire is wound and unwound through the clockwise and anticlockwise rotating of the synchronous motor, and in this way, the explosive in the explosive charging barrel is carried into the blast hole. By using a PLC, the rotating speed of the synchronous motor can be changed, and the labor intensity of constructors is greatly reduced. By adopting the synchronous motor, the unwinding process is more stable and rapid. A pressure sensor and an electric control switch are arranged at the bottom of the explosive charging barrel. The auxiliary device for charging the blast hole with the explosive during detonating construction is convenient to use.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to an auxiliary device for blasthole charging in blasting construction. Background technique [0002] At present, open-air step blasting is widely used in water conservancy and hydropower project slope excavation, stockyard mining, etc. The quality of the blasting effect directly affects the loading, transportation, and whether the graded ingredients can be directly filled on the dam. Among them, the charge quality is Important factors affecting the blasting effect. [0003] At present, the blasting charge of the open-air step is to directly put the explosive roll into the hole after the drilling is completed, and then fill the upper hole position. Because the depth of the step blasting drill hole is generally more than ten meters, the explosive roll moves in the hole approximately free-falling, and its huge impact force will make itself and the lower explosive roll become "short ...
