Description

Technical Field

[0001] This utility model relates to the field of blasting technology, specifically to a blasting tube fixing device. Background Technology

[0002] A blasting tube is a tubular device used to initiate or control an explosion. It typically contains explosives or blasting materials and releases energy through external triggering (such as electric detonators or detonating cords). It is widely used in mining, building demolition, geological exploration, and other fields. Its core function is to break rocks or structures through directional blasting. It must be operated in strict accordance with safety regulations.

[0003] During detonator installation, a blasting hole is typically drilled at a predetermined location before the detonator is inserted. Since the diameter of the blasting hole is usually larger than the outer diameter of the detonator, traditional methods require filling the hole with cement or other fillers after installation to ensure the stability of the detonator during operation. However, this operation is not only time-consuming and labor-intensive, but the filler also requires a long time to solidify, easily leading to project delays. Furthermore, once installation and filling are complete, replacing the detonator becomes extremely difficult, increasing the complexity of construction adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a device for fixing rupture tubes, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A rupture tube fixing device includes two annular supports. A first airbag is disposed on the inner side of each annular support, and a second airbag is disposed on the outer surface of each annular support. A first connecting pipe and a second connecting pipe connect the two annular supports. The first connecting pipe connects the two second airbags to each other, and the second connecting pipe connects the two first airbags to each other. A first air inlet pipe is connected to the outer surface of one annular support. One end of the first air inlet pipe communicates with the first airbag, and the other end of the first air inlet pipe is fitted with a first connector. A second air inlet pipe is connected to the outer surface of another annular support. The end of the second air inlet pipe is connected to a first inflation pipe via a connecting mechanism, which allows the first inflation pipe to be separated from the second air inlet pipe at a distance.

[0007] It can be seen that by inflating the first and second airbags, the bursting tube can be quickly fixed deep in the burst hole. Furthermore, through the connection mechanism, workers can separate the first inflation tube from the second air inlet tube from a distance outside the burst hole, thereby allowing the first inflation tube to be recycled and reused, reducing the waste of consumables.

[0008] Furthermore, the connecting mechanism includes a second connector installed at the end of the second air intake pipe. A piston is slidably and sealed inside the second connector, and a first inflation pipe is connected to the piston. A through hole is provided inside the piston, through which the first inflation pipe communicates with the second air intake pipe. Stops are installed on both sides of the outer surface of the second connector via elastic mechanisms. A third airbag is disposed on the outer surface of the first inflation pipe between the two stops, and the outer surface of the third airbag is connected to the second inflation pipe.

[0009] Furthermore, the elastic mechanism includes an L-shaped block mounted on the outer surface of the second connector. Two parallel guide rods are connected to the outer surface of the block, with the ends of the guide rods extending to the other side of the L-shaped block. Springs are fitted onto the outer surfaces of the guide rods, with both ends of the springs connected to the block and the L-shaped block, respectively.

[0010] Furthermore, an end cap is installed at the end of the guide rod away from the stop.

[0011] Furthermore, one-way valves are provided on the outer surfaces of both the first and second air intake pipes.

[0012] Furthermore, a groove is formed on the outer surface of the annular bracket, and the second airbag is installed inside the groove.

[0013] Furthermore, there are four of each of the first and second connecting pipes, and the four first connecting pipes and the four second connecting pipes are arranged in a ring array.

[0014] Furthermore, the piston has a connecting thread groove inside, and the outer surface of the first connector has an external thread that matches the connecting thread groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model inflates the two first airbags through the first air inlet pipe, causing them to expand and wrap around the outer surface of the rupture tube, thereby fixing the rupture tube inside the two annular supports. Then, it inflates the two second airbags through the second air inlet pipe, causing them to expand and press against the inner wall of the rupture hole, thereby quickly fixing the rupture tube inside the rupture hole, improving the project progress. Furthermore, the rupture tube can be replaced after fixing, reducing the complexity of construction adjustments.

[0017] 2. By setting up a connecting mechanism, when the rupture tube is fixed deep in the rupture hole, the worker can separate the first inflation tube from the second air inlet tube from a distance outside the rupture hole, thereby recovering and reusing the first inflation tube and reducing the waste of consumables.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a rupture tube fixing device, comprising two annular supports 100. A first airbag 101 is disposed on the inner side of each annular support 100, and a second airbag 102 is disposed on the outer surface of each annular support 100. A first connecting pipe 103 and a second connecting pipe 107 connect the two annular supports 100. The first connecting pipe 103 connects the two second airbags 102 to each other, and the second connecting pipe 107 connects the two first airbags 101 to each other. A first air inlet pipe 104 is connected to the outer surface of one of the annular supports 100. One end of the first air inlet pipe 104 is connected to the first airbag 101, and the other end of the first air inlet pipe 104 is fitted with a first connector 105. A second air inlet pipe 106 is connected to the outer surface of one of the annular supports 100. The end of the second air inlet pipe 106 is connected to a first inflation pipe 108 via a connecting mechanism 200. The connecting mechanism 200 allows the first inflation pipe 108 to be separated from the second air inlet pipe 106 at a distance.

[0027] In use, the worker places both annular supports 100 over the outside of the rupture tube. Inflation is then introduced into one of the first air bladders 101 through the first air inlet pipe 104. Through the connection of the second connecting pipe 107, both first air bladders 101 expand simultaneously, encasing and securing the rupture tube. Next, the first inflation pipe 108 is connected to the second air inlet pipe 106 via the connecting mechanism 200. The annular supports 100 and the rupture tube are then placed into the rupture hole. Once the rupture tube is deep within the rupture hole, inflation is then introduced through an external inflation device (not shown in the figure). Inflation is performed on the inflation tube 108, and the gas enters one of the second airbags 102. Through the connection of the first connecting tube 103, the two second airbags 102 expand simultaneously and press against the inner wall of the rupture hole, thereby quickly fixing the rupture tube inside the rupture hole. Then, through the connecting mechanism 200, the first inflation tube 108 is separated from the second air inlet tube 106 at a distance outside the rupture hole. The first inflation tube 108 is then pulled out from the rupture hole, so that the first inflation tube 108 can be recycled and reused, reducing the waste of consumables.

[0028] Preferably, the connecting mechanism 200 includes a second connector 201 installed at the end of the second air intake pipe 106. A piston 202 is slidably and sealed inside the second connector 201, and a first inflation pipe 108 is connected to the piston 202. A through hole is provided inside the piston 202, and the first inflation pipe 108 communicates with the second air intake pipe 106 through the through hole. Both sides of the outer surface of the second connector 201 are equipped with stops 203 by elastic mechanisms 300. A third airbag 204 is provided on the outer surface of the first inflation pipe 108 and located between the two stops 203. The outer surface of the third airbag 204 is connected to the second inflation pipe 205.

[0029] The piston 202 is inserted into the second connector 201, and the stop block 203 blocks the piston 202 so that the piston 202 cannot be pulled out of the second connector 201. When air is inflated into the first inflation tube 108, the gas enters the second connector 201 and then enters the second air inlet tube 106, thereby achieving the purpose of inflating the second airbag 102.

[0030] Because the rupture hole is often quite deep, the first inflation tube 108 is also quite long. If it is not pulled out, the first inflation tube 108 will be damaged along with the rupture tube when it explodes. Therefore, after the rupture tube is fixed, air can be injected into the second inflation tube 205 through an external inflation device to inflate the third airbag 204. The inflated third airbag 204 pushes the stop blocks 203 to both sides, separating them from the surface of the piston 202 and removing the obstruction. At this time, the first inflation tube 108 can be pulled directly to pull the piston 202 out of the second connector 201, or air can be injected into the first inflation tube 108 to increase the air pressure inside the second connector 201 and push the piston 202 out of the second connector 201. Then the first inflation tube 108 can be pulled out of the rupture hole and reused, reducing the waste of consumables.

[0031] Preferably, the elastic mechanism 300 includes an L-shaped block 301 mounted on the outer surface of the second connector 201. Two parallel guide rods 302 are connected to the outer surface of the stop 203, with the ends of the guide rods 302 extending to the other side of the L-shaped block 301. A spring 303 is sleeved on the outer surface of the guide rods 302, with both ends of the spring 303 connected to the stop 203 and the L-shaped block 301, respectively.

[0032] The two guide rods 302 limit the movement of the stop 203, preventing it from rotating and allowing it to move only horizontally. Under the force of the spring 303, the stop 203 moves to the outside of the piston 202 to block it, preventing the piston 202 from being pulled out of the second connector 201. When the third airbag 204 inflates, it pushes the two stop blocks 203 away from the piston 202 and compresses the spring 303. At this time, the blocking effect of the stop blocks 203 on the piston 202 is released, allowing the piston 202 to be pulled out of the second connector 201.

[0033] Preferably, the end of the guide rod 302 away from the stop 203 is equipped with an end head 400.

[0034] The end 400 can limit the guide rod 302, preventing it from falling off the L-shaped block 301 and being lost during use or assembly.

[0035] Preferably, a one-way valve 500 is provided on the outer surface of both the first air intake pipe 104 and the second air intake pipe 106.

[0036] By setting the one-way valve 500, the gas can only flow in one direction. When the piston 202 is pulled out from the second connector 201 or separated from the first connector 105, the first airbag 101 and the second airbag 102 will not depressurize.

[0037] Preferably, the outer surface of the annular bracket 100 is provided with a groove 600, and the second airbag 102 is installed inside the groove 600.

[0038] By setting the groove 600, when the second airbag 102 is in a depressurized state, it retracts into the groove 600, avoiding the second airbag 102 from contacting the inner wall of the rupture hole during the process of inserting the annular bracket 100 into the rupture hole, which would increase frictional resistance and even cause the second airbag 102 to rupture.

[0039] Preferably, there are four first connecting pipes 103 and four second connecting pipes 107, and the four first connecting pipes 103 and the four second connecting pipes 107 are arranged in a ring array.

[0040] The first connecting pipe 103 and the second connecting pipe 107 not only serve the function of gas conduction, but also connect the two annular supports 100 together, ensuring the reliability of the overall structure.

[0041] Preferably, the piston 202 has a connecting thread groove 700 inside, and the outer surface of the first connector 105 is provided with an external thread that matches the connecting thread groove 700.

[0042] When inflating the first airbag 101, the connecting threaded groove 700 can be screwed onto the outside of the first connector 105, and then the first airbag 101 can be inflated by an external inflation device. The first airbag 101 and the second airbag 102 share the same piston 202, making it more convenient to use.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
