Description

Technical Field

[0001] The utility model relates to the field of on-site mixed emulsion explosive vehicles, in particular to an emulsion explosive delivery tube retracting and releasing device. Background Art

[0002] In tunnels, mountain excavation or other scenarios where blasting is required, emulsion explosives are widely praised for their high explosive density, fast detonation speed and high intensity. Among them, there are many types of emulsion explosives, including open-pit emulsion explosives for open-pit mines, rock-type emulsion explosives for medium-hard rock blasting, and permissible emulsion explosives for underground coal mines.

[0003] However, the existing emulsion explosives have poor storage stability and quality stability, which need further improvement. Based on this, the use of emulsion explosives is mostly on-site configuration to ensure the effectiveness and stability of the explosives. When blasting the tunnel excavation face, it is not only necessary to configure the emulsion explosives on-site, but also to transport the configured emulsion explosives to various locations in the tunnel.

[0004] How to better transport emulsion explosives to various locations in the tunnel and to the explosives filling holes at various locations has become an urgent problem to be solved. In the existing technology, an on-site explosive mixing vehicle has been developed to address this problem. After the mixing is completed, the explosives are transported to the explosives filling holes through pipes and telescopic mechanical arms. In the actual laying process, the drug delivery pipes are long, which is not easy to manage, and it is even more inconvenient to lay the explosives in the explosives filling holes.

[0015] As a preference, an encoder is also provided on the axis of the driving gear; the beneficial effect of this preference is that, through the provision of the encoder, the rotation speed of the driving gear can be calculated, thereby facilitating the control of the pipe delivery accuracy of the pipe delivery mechanism.

[0016] As a preferred embodiment, an anti-dropout clamp is provided on the outer side of the drug outlet of the drug delivery tube; the beneficial effect of this preferred embodiment is that the anti-dropout assembly can effectively prevent the tube from falling off from the tube delivery mechanism.
