Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of explosive loading, and more specifically, it relates to a bending guide device for explosive loading tubes. Background Technology
[0002] Emulsion explosives (referring to civilian explosives) are made by sensitizing an emulsion matrix with a sensitizer. An emulsion explosive field mixing truck is a loading machine for loading bulk emulsion explosives. When using explosives, the explosives need to be transported from the mixing truck to the boreholes prepared on the ground or wall through pipelines. Since the angle of the boreholes is not fixed, the explosive outlet needs to be able to tilt to adapt to different borehole angles.
[0003] In existing technologies, a robotic arm is generally used to insert the hose into the blast hole. When the blast hole angles are inconsistent, the robotic arm is used to adjust the angle of the hose. For example, Chinese invention patent application number CN202311534146.X discloses a precise hole-aligning mechanism for a robotic arm of a vehicle for mixing emulsion explosives in an open-pit mine. The mechanism includes a base, a front seat, and a linkage assembly connecting the base and the front seat. The linkage assembly includes a first link hinged at both ends. The other ends of the two hinged first links are respectively hinged to the two ends of a telescopic cylinder. The opening angle of the two adjacent first links can be adjusted by extending and retracting the telescopic cylinder. The first link closer to the base is connected to the base, and the first link closer to the front seat is connected to the front seat. An outlet conduit is connected to the end of the front seat away from the linkage assembly.
[0004] Since the construction environment is mostly open-pit or underground mines with harsh working conditions, in the current technology, multiple hydraulic cylinders need to be connected to hydraulic oil pipes. If a hydraulic oil pipe is damaged due to the squeezing and collision of rocks during the construction process, it will cause equipment failure, resulting in a high failure rate of the equipment.
