A large-hole blasting charging device

Abstract

This invention discloses a large-hole blasting charging device, belonging to the technical field of charging devices. It includes a nylon rope, which hooks a bomb via a hooking mechanism. The hooking mechanism includes a first arc-shaped block and a second arc-shaped block; a connecting mechanism; and a replacement mechanism. By setting up the hooking mechanism, the second arc-shaped block hooks the explosive. During charging, after the explosive cartridge is placed at the bottom of the hole, the nylon rope is quickly pulled up. Due to inertia, the force on the spring is much greater than the weight of the explosive, causing the spring to deform. Rotation occurs between the first and second arc-shaped blocks, and the second arc-shaped block separates from the explosive, thus unhooking the explosive. The spring force is selected to be greater than the weight of a single emulsion explosive. During the charging process, the explosive is prevented from falling off, avoiding affecting the blasting effect. This method avoids the problem of the rope becoming entangled after detaching from the explosive, improving operational safety and construction efficiency. This method is applicable to all large-hole blasting charging operations, both on the surface and underground.

Description

Technical Field

[0001] This invention relates to the field of explosive charging devices, specifically a large-hole blasting explosive charging device. Background Technology

[0002] In recent years, the country has attached increasing importance to mine safety production, and underground blasting operations are an important part of safety assurance. At present, the high-efficiency large-diameter deep-hole stage open-field subsequent filling mining method is adopted for thick ore bodies in inclined and steeply inclined mines. The large-diameter deep-hole blasting method adopts the following construction sequence: blast hole layout → drilling construction → charging → filling → network connection → network inspection → warning → detonation → blast verification.

[0003] On-site loading procedure: 1. Directly (using a hoisting rope) slowly lower the detonating charge with detonating cord into the borehole; 2. Using a hoisting rope, lower the cylindrical explosive charge one by one into the borehole; 3. Estimate the loading position based on the amount of explosive placed into the borehole, and stop loading when it is close to the design-required loading position; 4. Lower a measuring rope into the borehole and use the measuring rope to measure the height reached by the explosive charge; continue until the explosive charge is loaded to the design-specified borehole depth.

[0004] Currently, the tool used for large-scale explosive loading is a nylon rope with an iron hook attached to one end. During loading, the S-shaped iron hook is used to hold the explosive, and then the nylon rope with the iron hook is used to slowly lower the explosive to the bottom of the hole. Several problems exist during this process: First, the hook portion of the nylon rope is too long, making it difficult to separate the iron hook from the explosive after it's placed at the bottom of the hole. Second, if the hook is too short, the explosive is prone to falling off, posing a significant safety hazard. Third, dealing with rope entanglement can damage the detonating cord or detonator wire, affecting the blasting effect. Therefore, improvements to the iron hook portion of the rope are urgently needed. Summary of the Invention

[0005] The purpose of this invention is to address the problems of excessively long hooks at the ends of nylon ropes, making it difficult to separate the rope hooks from the explosives after the explosives are placed at the bottom of the hole; and the explosives easily falling off if the hook head is too short, posing a significant safety hazard; and the damage to the detonating cord or detonator strands caused by rope entanglement, which affects the blasting effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up a hooking mechanism, the second arc-shaped block hooks the explosive. When loading the explosive, after the explosive roll is placed at the bottom of the hole, the nylon rope is quickly pulled up. Due to inertia, the force borne by the spring is much greater than the weight of the explosive. The spring deforms, and the first and second arc-shaped blocks rotate. The second arc-shaped block rotates and separates from the explosive, thus completing the unhooking of the explosive. The spring force is selected to be greater than the weight of a single emulsion explosive. During the loading process, it is ensured that the explosive does not fall off, so as to avoid affecting the blasting effect. It can avoid the problem of the rope getting tangled after it is detached from the explosive, improve the safety factor of the operation, and improve the construction effect. This method is applicable to all large-hole blasting and loading operations on the surface and underground.

[0018] 2. By setting up a replacement mechanism, when installing the spring, the vertical block faces downwards, then the mounting post is inserted into the mounting hole, and the vertical block passes through the vertical groove. After completion, the second connecting block is rotated so that the vertical block faces upwards, and then the mounting block is inserted into the mounting groove, thus completing the installation of the spring. When the connecting post is inserted into the hanging ring, the connecting post contacts the reinforcing block, pushing the reinforcing block to move, causing compression deformation of the elastic sheet. The reinforcing block moves into the reinforcing groove, thereby reinforcing the mounting block and thus reinforcing the spring, preventing the spring from loosening during use, facilitating the replacement of the spring, and thus adapting to different weights of medicine rolls.
