Embodiment 1

[0030] see Figure 1-3 , a precise directional demolition device based on electromagnetic force, which comprises a magnetic high-hardness stainless steel cylinder 1, and the interior of the high-hardness stainless steel cylinder 1 is provided with an electromagnetic box device 2 for providing electromagnetic properties, the electromagnetic box A plurality of electromagnetic coil chambers 3 are arranged inside the device 2 , and a bus line system 4 for controlling the energization of each electromagnetic coil is arranged inside the electromagnetic coil chambers 3 . This device can better control the blasting intensity and blasting angle, and does not use explosives to avoid the generation of harmful substances, because the magnets are divided into blocks, so that the blasting point can be accurately controlled, thereby accurately controlling the blasting angle and collapse. Position, each high-strength magnetic block is independently connected to the electromagnetic coil box, w...

Embodiment 2

[0039] A precise directional breaking device based on electromagnetic force and a method for using the same, comprising the following steps:

[0040] Step1: First drill the blasting part of the blasting object, then place the demolition device into the blasting hole, turn on the power switch of the device, and start the internal general circuit system;

[0041] Step2: According to the collapsed position of the blasting object, select the appropriate number and position of demolition magnetic blocks through the industrial computer, connect the corresponding electromagnetic coil chamber circuit, and adjust the current flow according to the required magnetic force;

[0042] Step3: After reaching the current intensity of the required magnetic force, turn on the control switch. According to the principle of repulsion at the same level, the high-hardness stainless steel magnetic block at the corresponding point pops up, and the demolition object is destroyed by tension;

Abstract

The invention provides a precise directional forcible entry device based on electromagnetic force and a using method thereof.The precise directional forcible entry device comprises a high-hardness stainless steel cylinder with magnetism, electromagnetic box equipment used for providing electromagnetism is arranged in the high-hardness stainless steel cylinder, and a plurality of electromagnetic coil chambers are arranged in the electromagnetic box equipment; and a main circuit system for controlling each electromagnetic coil to be electrified is arranged in the electromagnetic coil chamber. According to the device, the blasting strength and the blasting angle can be well controlled, no explosive is used, so that generation of harmful substances is avoided, the blasting point position can be accurately controlled due to the fact that the magnets are subjected to partitioning treatment, the blasting angle and the collapse position are accurately controlled, each high-strength magnetic block is independently connected with the electromagnetic coil box, and the electromagnetic coil box is convenient to use. The magnitude of the magnetic force is controlled by controlling the intensity of the current.

Description

technical field [0001] The invention belongs to the technical field of blasting engineering, and in particular relates to a precise directional blasting device based on electromagnetic force and a method for using the same. Background technique [0002] In engineering construction, it is often necessary to blast some areas of the construction environment. In the field of existing blasting technology, blasting tubes filled with explosives are often inserted into prefabricated blastholes in the construction environment, and electric detonators are used for long-distance blasting. The way to detonate the blast tube. However, the toxic gases, shock waves, and flying stones generated during blasting will adversely affect the surrounding environment. If the demolition building is in the city, uncontrollable factors such as blasting intensity and collapse orientation may also lead to safety accidents. SUMMARY OF THE INVENTION [0003] In order to solve the above technical probl...
