Hot melting alloy constrained type blasting device

Abstract

The invention discloses a hot melting alloy constrained type blasting device, and belongs to the technical field of blasting. The device comprises a blasting propagation component, hot melting alloy actuators, a drive spring, a steel ball, a state switch, an electric detonator, a blasting component, a body, a pressure screw, a large pressure screw and a screw; at ordinary, two hot melting alloy actuators lock the blasting propagation component on the position away from the electric detonator, meanwhile, the state switch carries out short-circuit protection on the electric detonator and achieves the state indication function, even if the electric detonator plays an unexpected action, the blasting component cannot be detonated, after the hot melting alloy actuators are powered on and act, the locking on the blasting propagation component is relieved, the drive spring drives the blasting propagation component to move to be in the state aligned with the electric detonator, the state switchconverts and relieves the short-circuit protection on the electric detonator, and when any electric detonator acts, the blasting propagation component can be blasted, and the blasting propagation component blasts the blasting component. The device has the beneficial effects of being capable of being controlled remotely, high in safety, reliable in action, capable of achieving state indication andthe like.

Description

technical field [0001] The invention belongs to the technical field of blasting, in particular to a hot-melt alloy constrained blasting device. Background technique [0002] With the rapid development of blasting technology, tasks such as building blasting and dangerous goods detonation tend to be diversified and complicated. More and more blasting devices need to have the characteristics of remote control, reliable function, and high safety. [0003] The current blasting initiation end usually adopts electric detonator or nonel detonator to detonate, and nonel detonator or electric detonator is used as the initiation end, which is usually easily disturbed by static electricity, radio frequency electricity and stray current, which is easy to cause premature explosion accidents. poses a greater safety hazard. Contents of the invention [0004] In view of the above defects or improvement needs of the prior art, the present invention provides a hot-melt alloy constrained bla...
