Laying and limiting device for underground explosive conveying pipe and explosive truck

According to the laying and limiting device for the underground explosive conveying pipe, the explosive conveying pipe is erected on the supporting rod provided with the functional part, so that the explosive conveying pipe is lifted by a certain height, friction between the explosive conveying pipe and the ground is reduced, friction force can be reduced by sliding the explosive conveying pipe on the pulley, and the explosive conveying pipe is prevented from falling off. The problems that the explosive conveying pipe of an on-site mixed loading emulsion explosive truck is strenuous to move and the explosive conveying pipe is easily scratched are solved, and the material consumption cost is reduced; when the explosive conveying pipe far away from a blast hole cannot reach the blast hole, the device can drive the auxiliary fixing base to be switched between the laying state and the fixing state through the connecting rotating shaft, the explosive conveying pipe is rapidly positioned and fixed, the problems tha
