Problems solved by technology

[0004] However, this method adopts rope suspension or fixes explosives on the rod, which is greatly affected by natural wind. When there is wind, the support rod and the rope fixed on the support rod are prone to swing, and the test device is unstable, which is inconvenient. Test, in this case the test data error is relatively large

Embodiment 1

[0017] Example 1 ,Such as figure 1 , figure 2 , Figure 5 As shown, the connecting frame 2 is composed of two vertically intersecting plates 21, and the plates 21 are a kind of profiles. The plates 21 may also have a concave-convex structure to increase their strength. The cross part is welded and connected, and one end of the coupling frame 2 is vertically fixed on the support frame 1, that is, the lower end of the vertical plate 21 is fixed on one side of the vertical plate 15 of the support frame 1, and two plates 21 are provided with positioning holes 22, A pin hole is provided at the central part of the coupling frame 2, and a profile tube 3 is assembled on the vertical plate 21 of the coupling frame 2. The profile tube 3 is a flat profile tube, and the profile tube 3 is mainly used to ensure To reduce weight under the condition of strength, of course, it is also possible to use other profiles with the same function. A pin hole is also processed in the middle of the ...

Embodiment 2

[0021] Example 2 ,Such as Figure 4 As shown, the type tube 3 is assembled on the horizontal plate 21, that is, the type tube 3 is horizontally arranged on the coupling frame 2, so that the soft rope 6 is also in a horizontal state, and the main drug package and the issued drug package are also installed on the soft rope 6 , and insert a No. 8 detonator at one end of the main charge pack, the insertion depth is 2 / 3 of the length of the detonator, and the energy-gathering hole of the detonator faces the direction of the charge pack, after detonation, both the main charge pack and the charge pack will explode It means that the explosive package has been detonated, and the distance between the main explosive package and the issued explosive package is increased for experiments, and the maximum distance between three consecutive explosions is taken as the detonation distance of the explosive.

[0022] The device can test the detonation distance when the explosive package is in a...

Abstract

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.

Description

technical field [0001] The invention relates to a device for testing the detonation distance of explosives. Background technique [0002] Sacrificial explosion is the phenomenon that after the explosion of explosives, another explosive package can be triggered to explode at a certain distance. When the probability of detonation is 100%, the distance between the main explosive charge and the explosive charge is called the detonation distance. When the probability of the explosive charge being detonated is 0%, the distance between the main propellant charge and the propellant charge is called the detonation safety distance. The main factors affecting the detonation are the shock wave overpressure generated by the main charge, the action time and temperature, the radius of the fireball, the impact energy of the high-speed particles of the detonation product, the sensitivity and geometric size of the charge to be fired, and the different pairs of charges to be fired.
