Problems solved by technology

This method is affected by human operation in the measurement process, and the error is large: 1. The probe is made of copper core enameled wire with a diameter of 0.1-0.15mm. When the charge is inserted, the resistance of the explosive may bend the probe, which has a certain influence on the detonation velocity. 2. Different probes are inserted into the charge coils independently by humans, and it cannot be guaranteed that the probes at adjacent ends are completely parallel, which has a certain impact on the detonation velocity; 3. When performing the detonation velocity test of mixed explosives, due to the high temperature of the mixed explosives on site , high viscosity, when tested in pvc pipe, due to the action of foaming agent, the copper probe will be bent, which will affect the accuracy of detonation velocity test results

Embodiment 1

[0022] Embodiment one: if figure 1 , figure 2 and image 3 As shown, an auxiliary device for explosive detonation velocity testing includes a cylindrical rod body 1 made of PVC material and three auxiliary probe columns 2, wherein the rod body 1 is composed of two sub-rods, and the two sub-rods are connected by threads. The side wall of the rod body 1 is axially provided with a wire installation groove 3, and two snap wire buckles 8 are uniformly arranged on the notch of the wire installation groove 3,

[0023] Among them, the auxiliary probe column 2 is composed of three sub-columns, and the adjacent sub-columns are connected by clamping or threading, and a probe installation groove 4 is axially provided on the side wall of each auxiliary probe column 2, and the probe is installed Buckles 7 are respectively provided on the outer end and inner end of the notch of the groove 4, and the inner end of the auxiliary probe column 2 is vertically connected with the rod body 1 by c...

Embodiment 2

[0024] Embodiment two: if Figure 4 As shown, when other structures are the same as in the first embodiment, as a modification, an adhesive layer 5 is provided at the bottom of the probe installation groove 4, and the adhesive layer 5 is a rubber layer. A cover plate 6 is arranged on the notch of the probe installation groove 4 . It is convenient to arrange the sensor probes, and at the same time, the cover plate 6 can further prevent the sensor probes from being displaced and deformed during the process of arranging and inserting explosives.

Abstract

The invention discloses an auxiliary device for testing the explosive velocity of an explosive. The auxiliary device comprises a rod body and at least two auxiliary probe columns, a wire installation groove is axially formed in the rod body, each auxiliary probe column is axially provided with a probe installation groove, the inner end of each auxiliary probe column is connected with the rod body, the probe installation grooves communicate with the wire installation groove, and the outer end of each auxiliary probe column is a sharp end. The auxiliary device is simple to operate and can test the explosive velocity of the explosive only by inserting the auxiliary probe columns into the explosive, the distance between two probes does not needed to be measured again, the problems that the sensor probe is bent and is not parallel in the insertion process during measurement and a copper core varnished wire is bent in the explosion process are effectively solved, the testing stability and accuracy are greatly improved, the lengths of both the rod body and the auxiliary probe columns are adjustable, the application environment is wide, and the auxiliary device can be conveniently popularized and applied; and the auxiliary device is simple in overall structure, low in cost and small in occupied space, and is convenient to carry and store.

Description

technical field [0001] The invention relates to the technical field of explosive detonation velocity testing, in particular to an auxiliary device for explosive detonation velocity testing. Background technique [0002] At present, the detonation velocity test of mixed explosives in the field of industrial explosives usually adopts the time meter method, that is, the electronic time meter is used to measure the time interval t between the two signals given by a pair of sensing elements installed at both ends of the explosive charge section, which is convenient. The average detonation velocity can be calculated. This method is affected by human operation in the measurement process, and the error is large: 1. The probe is made of copper core enameled wire with a diameter of 0.1-0.15mm. When the charge is inserted, the resistance of the explosive may bend the probe, which has a certain influence on the detonation velocity. 2. Different probes are inserted into the charge coils...
