Description

Technical Field

[0001] The invention belongs to the technical field of mobile explosive magazines, and in particular relates to a mobile explosive magazine provided with a neck folding structure. Background Art

[0002] Dangerous goods warehouses are places for storing and keeping dangerous goods such as flammable, explosive, toxic, and harmful materials. Because dangerous goods warehouses must ensure safety, existing dangerous goods warehouses are basically located in very remote locations. During the construction of various projects, it is often necessary to prepare one or two days of explosives. It is also very inconvenient to go to a remote dangerous goods warehouse to get explosives every day. Therefore, a temporary mobile explosives warehouse is basically installed on the construction site. The mobile explosives warehouse has the characteristics of simple installation, convenient transportation, short construction period, and can be reused. In particular, some projects have a short construction period. After the project is completed, the mobile explosives warehouse can be immediately disassembled and assembled to other construction sites for continued use. Some mobile explosives warehouses are equipped with a gradually closing structure, which can gather the shock wave generated by the explosion and needs to have a strong structural strength to withstand the large impact force. Because the volume of the mobile explosives depot is larger than that of ordinary explosion-proof containers, the overall structure of the folding structure is also larger, and it is difficult to use ordinary lathe turning processing methods to process it in one go. If multiple arc-shaped plates are used to splice together to form the folding structure, the processing process is very cumbersome, and the structural strength is difficult to meet the requirements of the folding part. Summary of the invention

[0003] The present invention aims at the drawback that the folding part of the mobile explosive magazine in the prior art is inconvenient to process, and provides a mobile explosive magazine with a neck folding structure. The folding structure of the mobile explosive magazine is formed by stacking a plurality of annular plates with different inner diameters, is easier to process, and has good structural strength.

[0004] The inventive objective of the present invention is achieved through the following technical solutions: a mobile explosives magazine provided with a neck folding structure, comprising a cylinder, a folding structure and a neck fixedly connected in sequence from bottom to top, the cylinder is a cylindrical structure, the neck is a circular ring structure, the inner diameter of the neck is smaller than the inner diameter of the cylinder, the center lines of the cylinder, the folding structure and the neck coincide, an explosion relief port is provided at the upper end of the neck, the folding structure comprises a plurality of circular ring plates stacked and fixedly arranged longitudinally, the center lines of all the circular ring plates coincide, upper and lower adjacent circular ring plates partially overlap, and the inner diameter of the circular ring plates gradually decreases from bottom to top.

[0005] In the above scheme, the folding structure is formed by fixing a plurality of circular plates together, and the circular plates can be processed from plates, the processing method is relatively simple, and a plate can be processed into a plurality of circular plates with different diameters, the utilization rate of the material is high, and the production cost of the folding structure can be reduced. The present invention also sets the explosion vent at the upper end of the neck, so that the shock wave generated by the explosion can be longitudinally depressurized through the explosion vent, and the folding structure can gather the shock wave and reduce the lateral destructive force of the shock wave, thereby shortening the safety distance required for the mobile explosives depot.

[0006] Preferably, the inner diameter of the lowermost circular plate is not larger than the inner diameter of the cylinder, and the inner diameter of the uppermost circular plate is not larger than the inner diameter of the neck.

[0007] Preferably, all the circular plates have the same thickness, the width of the circular plate at the bottom is greater than the thickness of the side wall of the cylinder, the width of the circular plate at the top is greater than the thickness of the side wall of the neck, and the outer side surface of the neck is flush with the outer side surface of the circular plate at the top, and the inner side surface of the circular ring at the top protrudes inward relative to the inner side surface of the neck. The circular plates have the same thickness, so that circular plates of different sizes can be cut from the same plate, which can improve material utilization and reduce production costs. At the same time, the width of the circular plate at the bottom is greater than the thickness of the side wall of the cylinder, and the width of the circular plate at the top is greater than the thickness of the side wall of the neck. Such a setting enables the folding structure formed by the combination of multiple circular plates to have good structural strength, and the structural strength of the folding structure is greater than the structural strength of the cylinder and the neck, which can meet the use requirements. The inner side surface of the circular ring at the top protrudes inward relative to the inner side surface of the neck. Such a setting can reduce the impact force of the shock wave gathered by the folding structure on the neck.

[0008] Preferably, the overlapping parts of the upper and lower adjacent circular ring plates are fixedly connected by welding.

[0009] Preferably, the outer diameter of the circular plate decreases gradually from bottom to top. This arrangement can reduce the outer diameter of the circular plate as much as possible without affecting the performance of the folding structure, thereby reducing the material of the circular plate and enabling more circular plates to be processed from a plate of a certain size.

[0010] Preferably, the folding structure is fixed with multiple layers of mutually parallel reinforcement structures, with intervals between adjacent reinforcement structures above and below, and the reinforcement structure includes multiple mutually parallel steel pipes, with intervals between adjacent steel pipes, and the steel pipes in the reinforcement structures at different levels are staggered, and the two ends of the steel pipes are fixedly connected to the inner side wall of the circular ring plate at the same height. The two ends of the steel pipe are fixedly connected to the circular ring plate, which can reinforce the circular ring plate. When the folding structure is subjected to the shock wave generated by the explosion, the steel pipe can generate an inward pulling force on the circular ring plate, making it difficult for the circular ring plate to expand outward, thereby improving the structural strength of the circular ring plate, and finally improving the structural strength of the folding structure. At the same time, the steel pipes in the reinforcement structures at different levels are staggered, so that the cooperation between the multi-layer protection structures can be used to prevent outsiders from entering the body of the explosives depot through the explosion vent position, playing a good protective and anti-theft role. If the explosive items in the explosives depot explode, the shock wave generated by the explosion will pass through the spacing between the steel pipes and the intervals between the reinforcement structures, and then spread to the outside through the explosion vents. The setting of the reinforcement structure will not affect the explosion venting function of the explosion vents. At the same time, when the shock wave generated by the explosion passes through the steel pipes, if the shock wave carries fragments, the steel pipes on the protective structure can block the fragments and prevent the fragments from causing damage to the outside world. The multi-layer protective structure can achieve multi-level blocking of fragments and can block most large-volume fragments, thereby improving safety performance.

[0011] Preferably, the steel pipe is provided with a plurality of vertical through holes, and the through holes on the steel pipe are evenly distributed along the length direction of the steel pipe. When the shock wave generated by the explosion passes through the reinforcement structure from bottom to top, it will also pass through the through holes of the steel pipe, so that the noise generated by the explosion and the shock wave can be reduced and silenced, which is consistent with the principle of a muffler.

[0012] Preferably, the spacing between the steel pipes in the reinforcement structure at different levels is equal, so that the distribution of the steel pipes is more uniform.

[0013] Preferably, except for the bottom reinforcement structure, the angles between the steel pipes in the reinforcement structures of the rest of the layers from bottom to top and the steel pipes in the bottom reinforcement structure gradually increase in equal steps, and the sum of the angle A between the steel pipes in the reinforcement structure of the second bottom layer and the steel pipes in the reinforcement structure of the bottom layer and the angle B between the steel pipes in the reinforcement structure of the top layer and the steel pipes in the reinforcement structure of the bottom layer is equal to 180°. This arrangement enables the steel pipes on the multi-layer reinforcement structure to cooperate with each other, and can evenly block and protect in all directions, so that the reinforcement structure has good anti-theft and protection functions.

[0014] Preferably, a protective cover is fixedly provided above the neck, and the edges of the protective cover protrude outward relative to the neck. The protective cover can protect against rainwater, thereby preventing rainwater from entering the explosives depot through the explosion vent. The protective cover is made of soft materials such as plastic, and softer materials are easily broken under the impact of shock waves, so that the installation of the protective cover does not affect the performance of the explosion vent. At the same time, when the protective cover made of softer materials is blown away by the shock wave, the destructive force caused by the protective cover to the outside world can be reduced.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the folding structure provided in the present invention has good structural strength, can effectively guide the shock wave, and the provided multi-layer reinforcement structure can further enhance the structural strength of the folding structure. At the same time, the present invention can play a good anti-theft, protective and noise reduction role, and will not affect the performance of the explosion vent. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0021] Example 1

[0022] like Figure 1-8As shown, a mobile explosives magazine with a neck folding structure comprises a cylinder 1, a folding structure 2 and a neck 3 which are fixedly connected in sequence from bottom to top. The cylinder 1 is a cylindrical structure, and an inlet and outlet 10 is opened on the side of the cylinder 1. An explosion-proof door 11 is installed at the inlet and outlet position. The neck 3 is a circular ring structure, and the inner diameter of the neck 3 is smaller than the inner diameter of the cylinder 1. The center lines of the cylinder 1, the folding structure 2 and the neck 3 coincide. An explosion vent 4 is arranged at the upper end of the neck 3. The folding structure 2 comprises a plurality of circular ring plates 5 which are stacked and fixedly arranged longitudinally, and the center lines of all the circular ring plates 5 coincide. The circular ring plates 5 adjacent to each other partially overlap, and the overlapping parts are fixedly connected by welding. The inner diameter of the circular ring plates 5 decreases gradually from bottom to top, and the inner diameter of the lowest circular ring plate 5 is not greater than the inner diameter of the cylinder 1, and the inner diameter of the highest circular ring plate 5 is not greater than the inner diameter of the neck 3. The outer diameter of the circular ring plates 5 decreases gradually from bottom to top. All the circular plates 5 have the same thickness, the width of the lowest circular plate 5 is greater than the thickness of the side wall of the cylinder 1, the width of the highest circular plate 5 is greater than the thickness of the side wall of the neck 3, and the outer side surface of the neck 3 is flush with the outer side surface of the circular plate 5 at the uppermost end, and the inner side surface of the uppermost circular ring protrudes inward relative to the inner side surface of the neck 3.

[0023] The folding structure 2 is fixed with multiple layers of mutually parallel reinforcement structures 6, with intervals between adjacent reinforcement structures 6 above and below. The reinforcement structure 6 includes multiple mutually parallel steel pipes 7, with intervals between adjacent steel pipes 7. The steel pipes 7 in the protection structures at different levels are staggered, and both ends of the steel pipes 7 are fixedly connected to the inner wall of the circular ring plate 5 at the same height. The steel pipes 7 are provided with multiple vertical through holes 8, and the through holes 8 on the steel pipes 7 are evenly distributed along the length direction of the steel pipes 7. The setting of the through holes 8 can play a role in silencing and reduce the noise generated by the shock wave. The spacing between the steel pipes 7 in the protection structures at different levels is equal. Except for the bottom protective structure, the angles between the steel pipes 7 in the protective structures of different levels from bottom to top and the steel pipes 7 in the bottom protective structure gradually increase in equal steps, and the sum of the angle A between the steel pipes 7 in the second bottom protective structure and the steel pipes 7 in the bottom protective structure and the angle B between the steel pipes 7 in the top protective structure and the steel pipes 7 in the bottom protective structure is equal to 180°. This arrangement makes the steel pipes 7 more evenly distributed, which can play a good role in intercepting fragments generated by the explosion.

[0024] In order to prevent rainwater from entering the explosives storehouse through the explosion vent 4, a protective cover 9 is fixedly installed on the upper end of the neck 3, and the edges of the protective cover 9 protrude outward relative to the neck 3. The protective cover 9 is made of soft plastic, and the softer material is easy to break under the impact of the shock wave, so that the installation of the protective cover 9 does not affect the performance of the explosion vent 4. At the same time, when the protective cover 9 made of the softer material is blown away by the shock wave, the destructive force caused by the protective cover 9 to the outside world can be reduced.
