Abstract

The invention discloses a detonator delay time tester. The detonator delay time tester comprises a tester body, an explosion box arranged inside the tester body and a test box arranged on the tester body, wherein the explosion box comprises a box body, a box cover and a sensing system; a base is arranged at the bottom of the box body; the sensing system is connected with the test box; the box comprises a reinforced steel plate, an outer steel plate, a rubber layer and an inner steel plate which are sequentially arranged from outside to inside; an upper opening is formed in the top of the outer steel plate; an inner chamber used for storing to-be-tested detonators is defined by the encircling of the inner steel plate; a lower opening is formed in the top of the inner steel plate; a box cover comprises an outer box cover, an inner box cover, an outer box cover handle and an inner box cover handle; the outer box cover is arranged at the upper opening; the outer box cover handle is fixedly connected with the outer box cover; the inner box cover is arranged at the lower opening; the inner box cover is fixedly connected with the inner box cover. The detonator delay time tester is simple in structure and convenient to operate, and is capable of safely and accurately testing.

Description

technical field [0001] The invention relates to a tester, in particular to a detonator delay time tester, which belongs to the technical field of detonator testing. Background technique [0002] At present, with the development of industrial technology, delayed detonators have been more and more widely used in engineering blasting, especially in the excavation process of open-pit mines. The blasting large block rate and the reduction of blasting flying stones have played a key role. Delayed detonators are divided into delayed electric detonators, delayed nonel detonators and electronic detonators, and the delay time of electronic detonators is set by the built-in chip of the detonator and the computer system. Yes, its delay time error is small, and it has been widely used in some projects that require high precision in delay time. Delay detonators can be divided into millisecond delay detonators, half-second delay detonators and second delay detonators according to the lengt...
