Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically a blasting device suitable for deep and long hole blasting. Background Technology

[0002] Mines include coal mines, metallic mines, non-metallic mines, building material mines, and chemical mines, among others. Mine size (also known as production capacity) is usually expressed as annual or daily output. Annual output refers to the quantity of ore produced by the mine each year. Based on output size, mines are classified into three types: large, medium, and small. The size of the mine must be commensurate with its economically reasonable service life; only in this way can infrastructure costs be saved and costs reduced. In the mining production process, extraction operations consume the most manpower, materials, and capital, but they also have the greatest potential for reducing mining costs. The main ways to reduce extraction costs are to improve labor productivity and product quality, and to reduce material consumption.

[0003] With the rapid development of human technology, the demand for energy is gradually increasing. Mines contain a large amount of natural mineral resources. During mining, it is necessary to install blasting tubes in blasting holes for targeted blasting. Currently, before engineering blasting, holes need to be drilled in the mountain and blasting tubes containing explosive charges need to be placed in the appropriate position within the blasting holes and fixed. However, the diameter of the blasting holes is often larger than the diameter of the blasting tubes. This causes the blasting tubes to shift or even slip during the explosion in some inclined or vertical blasting holes, making them difficult to fix. This results in unsatisfactory blasting effects and reduced accuracy. This device fixes the blasting tube by securing the top of the tube, preventing it from slipping during placement. Utility Model Content

[0004] The purpose of this invention is to provide a blasting device suitable for deep and long hole blasting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Preferably, the rupture tube is fixedly connected to a fixing block, the screw is fixedly connected to a turntable, the turntable is fixedly connected to a rotating rod, and the turntable is fixedly connected to a handle.

[0007] Preferably, the screw is threaded through the first groove in the middle of the fixing frame, and the bottom is threaded through the second groove in the middle of the fixing block.

[0008] Preferably, screw holes are provided on both sides of the upper side of the first connecting frame and the second connecting frame, and the first fixing rod and the second fixing rod pass through the screw holes and are threaded to the inner cavities of the first opening and the second opening at both ends of the fixing frame.

[0009] Preferably, a first slot and a second slot are provided on both sides of the top of the rupture tube, and a first fixing ring is fixedly connected to the bottom of the first connecting frame.

[0010] Preferably, a second fixing ring is fixedly connected to the bottom of the second connecting frame, and a first locking block and a second locking block are fixedly connected to one side of the first fixing ring and the second fixing ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This blasting device, applicable to deep and long hole blasting, drives the turntable to rotate clockwise by rotating the rotating rod. The bottom screw passes through the fixing frame and rotates downward until the threaded connection fixing block forms a fixed thread in the first groove in the middle, thus achieving the purpose of initially fixing the blasting tube.

[0013] 2. This blasting device, applicable to deep and long hole blasting, initially fixes the blasting rod with a top screw. The first fixing ring, the first locking block on one side of the second fixing ring, and the second locking block are connected to the first locking groove on both sides of the blasting tube, and the second locking groove further fixes the top of the blasting tube. Since the bottom of the blasting tube is facing downward after being lifted, the locking blocks on both sides will not detach from the locking groove.
