Industrial explosive detonation velocity measurement target line manufacturing device

Abstract

The invention discloses an industrial explosive detonation velocity measurement target line manufacturing device, which comprises an explosion-proof box body, and at least one group of pay-off mechanism, at least one group of threading mechanism and an explosive positioning assembly which are arranged in the explosion-proof box body, the threading mechanism is arranged on one side of the explosive positioning assembly; the threading mechanism comprises a threading driving part, a threading movable base and a crochet hook, one end of the crochet hook is fixed to the threading movable base, the threading driving part is used for driving the crochet hook to reciprocate between the two sides of the explosive positioning assembly, by arranging the pay-off mechanism and the threading mechanism, the target line can be rapidly manufactured and accurately installed, time and labor are saved, and the production efficiency is improved. Therefore, the detonation velocity measurement is more accurate. Besides, the pay-off mechanism and the threading mechanism are arranged in the anti-explosion box body, so that threading operation is carried out in the anti-explosion box body, automatic installation of the target line is achieved, direct contact between an operator and explosive in the threading process is avoided, and the problem that potential safety hazards exist when the target line is installed in the prior art is solved.

Description

technical field [0001] The invention relates to the field of industrial explosives, in particular to a target line manufacturing device for measuring the detonation velocity of industrial explosives. Background technique [0002] At present, the explosion velocity measurement of industrial explosives adopts a five-stage detonation velocity measuring instrument, which is used together with the target line. The surface insulating paint of the enameled round copper wire is melted by the high temperature at the moment of the explosive explosion, so that the circuit is turned on. By measuring the conduction time of the first target line to the second target line, the detonation speed of the explosive can be calculated. [0003] As an important performance index of explosives, the detonation speed is generally required to be no less than 4000m / s. In the actual measurement process, the production and installation of the target line, and the slight change of the distance will lead t...

Problems solved by technology

Therefore, the production of the existing target lines is purely manual, and it takes time and effort to make the target lines. Since three rolls of explosives are used to measure the detonation velocity by the five-stage method, a total of 15 target lines are used, so the labor intensity of target line production is high. And the efficiency is low, and when the target line is installed, first, the target line will not be installed in the center of the medicine roll; second, the perforation spacing of the upper and lower two target lines of the medicine roll is manually measured, and the distance error between the target line and the target line is large. Large, these errors will affect the accuracy of measurement data

[0004] In addition, the industrial explosive itself has needle-prick sensitivity, which may cause the explosive to explode when the steel needle is used to penetrate the target line, and the accumulation of static electricity carried by the human body may also cause the explosive to explode. Therefore, there are potential safety hazards in the process of installing the target line
