The specific embodiment
Below through embodiment and combine accompanying drawing that the technical scheme of the utility model is done further explain.
Like Fig. 1, shown in 2; The safety interlocking of this detonator delay time detecting; It comprises explosion-proof tank 4, blast wall 9, firing device 2, detonator delay time test appearance 1 and interlocking gear, and explosion-proof tank 4 tops are provided with muffler 6, and blast wall 9 is arranged between explosion-proof tank 4 and firing device 2, the detonator delay time test appearance 1; Firing device 2, detonator delay time test appearance 1 are placed on the desk 11; Blast wall 9 is provided with an explosion-proof window, and explosion proof door 8 is installed on the explosion-proof window, and explosion proof door adopts push-pull structure; Muffler 6 top movable of said explosion-proof tank 4 are connected with a lid 7, and lid 7 flexibly connects with muffler 6 one sides, and the junction is provided with the main shaft spring, and lid is provided with near switch; Be installed with electromagnet 3 and reset switch 10 on the said blast wall 9.
As shown in Figure 3; Described interlocking gear is by forming near switch, electromagnet, electromagnetic relay, firing device and power supply; Power supply is a low-voltage dc power supply; Adopt the low-voltage safety power supply of direct current 24V; Near switch S Q be closed type near switch, the positive pole of low-voltage dc power supply is through fuse F U and reset switch SB1, connect through lead near an end of the coil of the start button SB2 of switch S Q, firing device, electromagnetic relay KA successively, the other end of the coil of electromagnetic relay KA links to each other with the negative pole of low-voltage dc power supply; The first normally opened contact KA1 of electromagnetic relay KA is parallelly connected with the start button SB2 of firing device; The second normally opened contact KA2, one end of electromagnetic relay KA links to each other with the positive pole of low-voltage dc power supply through fuse F U, and the other end is connected with the end of electromagnet YV, and the other end of electromagnet YV links to each other with the negative pole of low-voltage dc power supply.
