[0002] Explosive bonding is a method of achieving solid metallurgical bonding between metal layers by using the instantaneous ultra-high pressure and ultra-high pressure impact energy generated by the explosion of explosives. The biggest feature of explosive bonding is that it can quickly and firmly weld most of the same or different metal materials together in a very short time to produce widely used bimetallic or even multi-metallic composite materials. Explosive bonding pipes prepared by explosive bonding are widely used in industrial fields such as oil fields, chemicals and electric power. Their scope of application is becoming more and more extensive, and the economic, environmental and social benefits they bring are also more obvious.

[0003] In the prior art, explosive composite tubes prepared by explosive composite are currently loaded by directly pouring explosives into the tube. If the tube is long, the density of the lower layer of explosives will increase due to gravity. The longer the tube is, the greater the density of the lower layer of explosives will be. This situation will be more obvious. Therefore, there will be obvious differences in the composite interface farther from the detonation position and uneven interface performance. The closer to the bottom base layer, the greater the deformation, which will cause the problem of excessive aperture deformation.

[0004] Therefore, a kind of explosive composite tube auxiliary charging device is needed. Utility Model Content

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the explosive composite tube auxiliary charging device of the utility model comprises a composite tube 1 and a fixed rod 2 arranged at the axial position of the composite tube 1, a plurality of stacked annular medicine boxes 3 are mounted on the fixed rod 2, the annular medicine boxes 3 comprise an annular bottom plate 3-1, an inner cylindrical plate 3-2 is vertically arranged on the inner circle of the annular bottom plate 3-1, the inner cylindrical plate 3-2 is gap-matched with the fixed rod 2, an outer cylindrical plate 3-3 is vertically arranged on the outer circle of the annular bottom plate 3-1, and the area enclosed by the outer cylindrical plate 3-3, the inner cylindrical plate 3-2 and the annular bottom plate 3-1 of the annular medicine box 3 is filled with explosives 4.

[0031] It should be noted that, by providing a fixing rod 2, it is convenient to stack and install multiple annular medicine boxes 3, and ensure that the multiple annular medicine boxes 3 are coaxial. By providing multiple annular medicine boxes 3 and filling each annular medicine box 3 with explosives 4, it is ensured that the amount of explosives 4 inside the composite tube 1 is evenly distributed from top to bottom, which effectively improves the charging process before explosive composite of longer pipes, and prevents the problem of uneven density of upper and lower layers of explosives 4 caused by gravity when directly charging in the composite tube 1, improves the stability and deformation uniformity of the joint surface of the explosive composite tube, improves the yield, and facilitates charging, and also prevents the explosives 4 from leaking out of the composite tube 1 to cause danger.

[0032] It should be noted that by controlling the structure of the annular medicine box 3, a container is formed by the outer cylindrical plate 3-3, the inner cylindrical plate 3-2 and the annular bottom plate 3-1 to be filled with explosives 4, and the clearance between the inner cylindrical plate 3-2 and the fixing rod 2 facilitates the stacking installation of multiple annular medicine boxes 3.

[0033] In this embodiment, the total height of the multiple stacked annular medicine boxes 3 is the same as the height of the multi-layer tube 1. By controlling the total height of the multiple stacked annular medicine boxes 3, the multiple annular medicine boxes 3 are filled in the multi-layer tube 1, further ensuring the uniform distribution of the explosive 4 in the multi-layer tube 1.

[0034] like Figure 1 As shown, in this embodiment, a support plate 5 is provided at the lower part of the fixing rod 2. By providing the support plate 5, after a plurality of stacked annular medicine boxes 3 are sleeved on the fixing rod 2, it is convenient to lift them together and install them in the multi-layer tube 1.

[0035] It should be noted that the diameter of the support plate 5 is smaller than the diameter of the annular medicine box 3 , so that a plurality of stacked annular medicine boxes 3 and the support plate 5 can be integrally mounted in the multi-layer tube 1 .

[0036] like Figure 4As shown, in this embodiment, a cylindrical baffle 3-4 is further provided in the annular medicine box 3 to divide the annular medicine box 3 into an inner circular area 3-5 and an outer circular area 3-6. By providing the cylindrical baffle 3-4, the annular medicine box 3 is divided into an inner circular area 3-5 and an outer circular area 3-6, and explosives 4 with different detonation velocities are installed in the inner circular area 3-5 and the outer circular area 3-6, so as to realize the preparation of explosive composite tubes of different standards, and the application range is wider.

[0037] It should be noted that the inner circular area 3-5 is filled with high-detonation-velocity explosives, and the outer circular area 3-6 is filled with low-detonation-velocity explosives, and the high-detonation-velocity explosives are used to detonate the low-detonation-velocity explosives.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, a base tube 6 is sheathed outside the composite tube 1, and a composite gap is left between the composite tube 1 and the base tube 6. The composite gap facilitates the composite tube 1 and the base tube 6 to be explosively composited into an explosive composite tube.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, four gap columns 7 are installed at the upper and lower parts of the installation gap, respectively, and the gap columns 7 are evenly distributed. By evenly arranging the gap columns 7, it is ensured that the gap between the composite pipe 1 and the base pipe 6 is equal everywhere, thereby improving the stability and deformation uniformity of the joint surface of the explosive composite pipe and improving the yield rate.

[0040] In this embodiment, an installation gap is left between the annular medicine box 3 and the multi-layer tube 1. The annular medicine box 3 is conveniently installed inside the multi-layer tube 1 by leaving the installation gap.

[0041] It should be noted that there is a 0.2 mm installation gap between the annular medicine box 3 and the multi-layer tube 1, which facilitates installation and does not cause the problem of deviation between the axis of the annular medicine box 3 and the axis of the multi-layer tube 1 due to excessive gap.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, a detonating cap 8 is inserted into the top of the explosive 4 of the uppermost annular medicine box 3. The explosive 4 is detonated by inserting the detonating cap 8.

[0043] In actual use, firstly, the number of annular medicine boxes 3 is determined according to the height of the composite tube 1, and then each annular medicine box 3 is filled with explosives 4, and multiple annular medicine boxes 3 filled with explosives 4 are stacked and mounted on the fixed rod 2, and the structure formed by the fixed rod 2 and the supporting plate 5 is placed as a whole in the composite tube 1 and the base tube 6 that are completely assembled on the ground 9, and detonating caps 8 are inserted into the explosives 4 in the layer of the topmost annular medicine box 3, and then the explosives 4 are detonated by the detonating caps 8, and the composite tube 1 and the base tube 6 are explosively composited to obtain an explosive composite tube. The explosive composite tube has a stable joint surface and uniform deformation, a high yield rate, and is easy to operate and easy to promote and apply.

[0044] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the technical essence of the utility model still falls within the protection scope of the technical solution of the utility model.
