Explosive sympathetic detonation distance testing device

The invention discloses an explosive sympathetic detonation distance testing device which comprises a supporting frame and a connecting frame. The connecting frame is composed of two plates which are vertically crossed, a sectional tube is arranged on one plate of the connecting frame, a connecting plate is relatively arranged at the two ends of the sectional tube, a thread hole is relatively formed in the connecting plate, a screw rod are arranged in the thread hole, and the opposite end of the screw rod is connected with a flexible rope used for placing of a test explosive. An H shape is formed by two horizontal plates and one longitudinal plate on the upper end face of the supporting frame, the two ends of the two horizontal plates are further connected with supporting legs, the supporting legs vertically extend downwards, universal wheels with the heights capable of being adjusted in a lifting mode are further arranged at the lower ends of the supporting legs, and a level gauge is arranged on the upper end face of the longitudinal plate of the supporting frame. The explosive sympathetic detonation distance testing device is stable and reliable and is not influenced by natural wind, operation is simple and convenient, the sympathetic detonation distance can be tested when an explosive bag is in a horizontal state or in a vertical state, the sympathetic detonation distances obtained in the two states are compared and analyzed, and the precision of the explosive sympathetic detonation distance test can be improved.
