AI Technical Summary
In existing technologies, long strip-shaped explosive bands are prone to vibration during rocket launch due to excessive length of a single segment, leading to knots, tangles, or entanglement, which affects the explosive effect.
A two-stage, multi-layer flexible explosive belt loading method is adopted, in which the explosive belt is divided into a first-stage belt and a second-stage belt. The belts are folded in multiple Z-shapes in the storage and transportation container, and the length of each stage is calculated so that the first end of the second-stage belt is connected to the last end of the first-stage belt, thus reducing vibration interference during the straightening process.
It effectively reduces the length of a single explosive strip, avoids problems such as knotting, entanglement, and winding caused by shaking, and improves the straightness of the explosive strip and the blasting effect.

TECHNICAL FIELD
[0001] The application relates to the technical field of blasting equipment, in particular to a filling method of a multilayer flexible blasting belt. BACKGROUND
[0002] In order to quickly clear a minefield, break a large range of obstacles such as barbed wire, and open a passageway for vehicles or personnel, the blasting belt in a rocket blasting device is generally designed into a long strip-shaped belt, which can be better stretched and straightened for blasting and obstacle clearing in wartime.
[0003] Generally, the blasting belt is folded into a multilayer Z-shaped structure in the box according to the length of the box of the storage and transportation launching box. When the length of the storage and transportation launching box is relatively long, the length of a single section of the blasting belt is also relatively long. After the rocket engine is launched, the blasting belt is driven to fly out. Since the length of a single section of the blasting belt is relatively long, when the single section of the blasting belt is pulled up, it is prone to shaking. The shaking of the single section of the blasting belt interferes with the rear section of the blasting belt, thereby more likely to cause knotting, linking or winding, affecting the smooth stretching and straightening of the blasting belt, and finally affecting the blasting effect. SUMMARY
[0004] The application designs a filling method of a two-section multilayer flexible blasting belt. The method can make the blasting belt better stretched and straightened when the rocket engine is launched.
[0005] The filling method of the multilayer flexible blasting belt comprises a storage and transportation launching box and a blasting belt. According to the internal length, width and height of the storage and transportation launching box and the length of the blasting belt, the blasting belt is divided into a one-section belt and a two-section belt, and the length of a single section of the blasting belt in the one-section belt and the length of a single section of the blasting belt in the two-section belt are calculated. The one-section belt is folded into a multilayer Z-shaped structure in one side of the storage and transportation launching box according to the length of a single section of the blasting belt in the one-section belt, and the two-section belt is folded into a multilayer Z-shaped structure in the other side of the storage and transportation launching box according to the length of a single section of the blasting belt in the two-section belt. The first end of the two-section belt is connected to the tail end of the one-section belt, and the first end of the two-section belt is located at the upper part of the two-section belt, and the tail end of the one-section belt is located at the lower part of the one-section belt.
[0006] Further, the upper part of the two-section belt after filling is flush with the upper part of the one-section belt after filling.
[0007] Further, the two-section belt after filling has an n-layer structure, and the one-section belt after filling has an n+m-layer structure, n and m are natural numbers greater than 0, and m≤5.
[0008] The application has the following beneficial effects: The explosion belt in the application adopts a two-section filling method, each section of the explosion belt is folded in a Z shape multiple times in the storage and transportation box, effectively reducing the length of a single section of the explosion belt, and to a certain extent, avoiding the shaking interference caused by the long length of a single section of the explosion belt, thereby greatly avoiding the problems of knotting, connecting and winding of the explosion belt during the straightening process, and improving the straightening degree of the explosion belt.

[0010] In order to make the above features and advantages of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below in conjunction with the drawings. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the application.

[0012] In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.

[0013] In this application, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise expressly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0014] In order to quickly clear the minefield, break the large range of obstacles such as barbed wire, and open the way for vehicles or personnel, the explosion belt in the rocket exploder is generally designed as a long strip belt, which can be better stretched and exploded to clear obstacles in wartime.
[0015] Generally, the explosion belt is folded and packed in a multi-layer Z-shaped structure in the box according to the length of the box of the storage and transportation launch box. When the length of the storage and transportation launch box is longer, the length of the single section of the explosion belt is also longer. After the rocket engine is launched, the explosion belt is driven out. Since the length of the single section of the explosion belt is longer, when the single section of the explosion belt is pulled up, it is easy to produce shaking. The shaking of the section of the explosion belt interferes with the rear section of the explosion belt, which may cause knotting, linking or winding, affecting the smooth stretching of the explosion belt, and ultimately affecting the blasting effect.
[0016] Referring to Figure 1 and 2 , the application provides a packing method of multi-layer flexible explosion belt, including storage and transportation launch box, explosion belt; According to the length, width and height of the inside of the storage and transportation launch box, and the length of the explosion belt, the explosion belt is divided into one section of belt 1 and two sections of belt 2, and the length of the single section of the explosion belt in the one section of belt 1 and the length of the single section of the explosion belt in the two sections of belt 2 are calculated; the one section of belt 1 is packed in a multi-layer Z-shaped folding manner according to the length of the single section of the explosion belt in the one section of belt 1 on one side of the storage and transportation launch box, and the two sections of belt 2 are packed in a multi-layer Z-shaped folding manner according to the length of the single section of the explosion belt in the two sections of belt 2 on the other side of the storage and transportation launch box; Wherein, the head end of the two sections of belt 2 is connected with the tail end of the one section of belt 1, and the head end of the two sections of belt 2 is located at the upper part of the two sections of belt 2, and the tail end of the one section of belt 1 is located at the lower part of the one section of belt 1.
[0017] It should be noted that the explosive belt in the present application is divided into a one-section belt 1 and a two-section belt 2 according to the final two-section folding mode of the explosive belt, which is for the convenience of description, and is not a physical division such as cutting, and it is still a complete explosive belt. The connection between the leading end of the two-section belt 2 and the trailing end of the one-section belt 1 is also a non-broken connection or a non-substance connection, which is for the convenience of description. In addition, the leading end of the one-section belt 1 is connected to the rocket engine through a traction rope, and the trailing end of the two-section belt 2 is connected to the fuse.
[0018] It can be understood that in the present application, the folding of the one-section belt 1 and the two-section belt 2 is carried out according to the internal space of the storage and transportation launch box, so the overall width of the one-section belt 1 and the two-section belt 2 after folding should be equal according to the width of the box; and the overall length of the one-section belt 1 and the two-section belt 2 after folding is preferably equal, but in fact it should be calculated according to the specific length of the explosive belt and the length of the box, so that the overall length of the two is approximately equal.
[0019] In the present application, by adopting a two-section loading method, each section of the explosive belt is folded in multiple Z shapes in the storage and transportation launch box, effectively reducing the length of a single section of the explosive belt. In the launching process, the one-section belt 1 is sequentially pulled out from top to bottom, from the trailing end of the one-section belt 1 to the leading end of the two-section belt 2, and then from top to bottom of the two-section belt 2, which can to some extent avoid the shaking interference caused by the long length of a single section of the explosive belt, thereby greatly possibly avoiding problems such as knotting, tangling, and winding of the explosive belt during the unfolding process, and improving the unfolding degree of the explosive belt.
[0020] It can be understood that the upper part of the two-section belt 2 after loading is flush with the upper part of the one-section belt 1 after loading.
[0021] According to the length of the explosive belt and the length, width, and height of the storage and transportation launch box to be loaded, the length of the two-section explosive belt and the length of a single section of the explosive belt can be accurately calculated, so that the upper part of the two-section belt 2 is flush with the upper part of the one-section belt 1, and the loading neatness of the explosive belt is ensured.
[0022] It can be understood that the two-section belt 2 after loading has an n-layer structure, and the one-section belt 1 after loading has an n+m-layer structure, where n and m are natural numbers greater than 0, and m≤5.
[0023] According to the length of the explosive belt and the length, width, and height of the storage and transportation launch box to be loaded, the length of the two-section explosive belt and the length of a single section of the explosive belt can be accurately calculated, so that the number of folding layers of the two-section belt 2 is less than the number of folding layers of the one-section belt 1. When the upper part of the two-section belt 2 is flush with the upper part of the one-section belt 1, the bottom of the two-section belt 2 leaves a certain space with the bottom of the storage and transportation launch box, and at this time the control device can be placed in the space to control the launching of the rocket exploder.
[0024] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the principles of the present application shall be included in the protection scope of the present application.
