Description

Technical Field

[0001] This invention relates to the field of blast protection technology, specifically to a gun cover connection device and a detachable gun cover. Background Technology

[0002] During blasting operations, blasting safety protection typically uses rubber tumblers made from recycled vehicle tires. These tumblers possess high strength, elasticity, and toughness, making them difficult to break. Furthermore, their own weight prevents them from being thrown up by the blast wave, providing good protection. However, in large-area blasting, due to the difficulty in customizing tumblers of the correct size, adjacent tumblers are usually joined together by binding their corners with steel wire to form a larger tumbler to meet blasting protection requirements. However, this connection method has the following drawbacks:

[0003] 1. The wear rate of the gun shells is high, and the steel wires connecting adjacent gun shells are easily broken and blown away by the impact of the blast gas.

[0004] 2. There are inevitably weak points at the joints of the cannons, and flying stones can easily fly out from the joints of two adjacent cannons, posing a certain safety hazard.

[0005] 3. The gun covers are connected by steel wires, which can easily damage them. They need to be repaired frequently, usually one repair per gun, which is inefficient and labor-intensive. Summary of the Invention

[0006] To overcome at least one of the aforementioned drawbacks, this invention provides a gun cover connecting device and a detachable gun cover. The objective of this invention can be achieved by employing the following technical solution:

[0007] A cannon-connecting device includes:

[0008] The mounting base is connected to the first firing unit;

[0009] A connector is attached to the second gunnery unit and is detachably attached to the mounting base;

[0010] The first blasting unit and the second blasting unit are arranged adjacent to each other.

[0011] In this process, the second gunnery unit moves away from the first gunnery unit along its own normal under airflow impact, so as to form a gap between the first gunnery unit and the second gunnery unit for airflow to pass through.

[0012] In one possible implementation, the fixing seat is disposed on the first surface of the first shelling unit, and the connecting member is disposed on the second surface of the second shelling unit. The connecting member is connected to the fixing seat so that a portion of the first surface and a portion of the second surface overlap.

[0013] In one possible implementation, the fixing base and the connector are provided in a one-to-one correspondence.

[0014] In one possible implementation, the fixing base is disposed on the edge region of the first gun bearing unit near the second gun bearing unit, and the connecting member is disposed on the edge region of the second gun bearing unit near the first gun bearing unit.

[0015] In one possible implementation, the fixing base includes:

[0016] Base;

[0017] A groove for accommodating the connector;

[0018] A sliding groove is formed on the end face of the base and communicates with the groove, so as to allow the connector to slide along the direction of the groove;

[0019] An unlocking hole is located at one end of the slide groove, for the connector to be inserted into or disengaged from the groove;

[0020] A locking hole, located at the other end of the slide groove, is used to limit the position of the connector sliding along the groove direction.

[0021] In one possible implementation, the connector includes:

[0022] The connecting rod is connected at one end to the second gun-bearing unit;

[0023] The limiting block is connected to the other end of the connecting rod.

[0024] In one possible implementation, the first and second shot-bearing units are elastically connected along the direction normal to the second shot-bearing unit itself.

[0025] In one possible implementation, the connector further includes:

[0026] An elastic element is provided to allow the fixed base and the connecting member to be elastically connected in the direction normal to the second gun unit itself.

[0027] In one possible implementation, the elastic element is sleeved on the connecting rod. When the connecting element and the fixed base are connected, the elastic element is located within the groove, with one end abutting against the inner wall of the groove and the other end abutting against the limiting block; or,

[0028] One end of the elastic element is connected to the connecting rod, and the other end of the elastic element is connected to the limiting block. The elastic element is located in the groove or can be inserted into the sliding groove.

[0029] A detachable gun cover includes the gun cover connecting device described in any one of the above, and further includes a plurality of first gun cover units and second gun cover units that are detachably connected by the gun cover connecting device.

[0030] The beneficial technical effects of this invention are as follows: According to this disclosure, the blasting shell connecting device and the detachable blasting shell detachably connect two adjacent blasting shell units together through a fixed base and a connector. By splicing several blasting shell units, the area that can be covered is increased. Several blasting shell units of fixed size facilitate production, transportation and assembly. The connection positions of two adjacent blasting shell units overlap without any gaps, which can effectively prevent flying stones from passing through the connection point. At the same time, by replacing the steel wire with the blasting shell connecting device, the force-bearing area is large and it is not easy to damage the blasting shell, reducing the workload of blasting shell maintenance. Moreover, a gap is formed between two adjacent blasting shell units to allow the blasting gas to pass through. Under the premise of effectively blocking flying stones, the blasting gas can be diverted, reducing the impact force of the blasting gas on the blasting shell unit and extending the service life of the blasting shell unit and the blasting shell connecting device.

[0055] In the following detailed disclosure, reference is made to the accompanying drawings, which illustrate specific embodiments that can be implemented. These embodiments are fully described by way of illustrations, which are part of the features. In order to enable those skilled in the art to understand and clarify the technical solution of the present invention more clearly, the embodiments described below are not limited thereto. The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0056] In this invention, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "link," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "link" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a gun-connecting device includes:

[0059] The mounting base 21 is connected to the first firing unit 11;

[0060] The connector 22 is connected to the second gunnery unit 12 and is detachably connected to the mounting base 21;

[0061] The first gun-bearing unit 11 and the second gun-bearing unit 12 are arranged adjacent to each other.

[0062] In this process, the second gunnery unit 12 moves away from the first gunnery unit 11 along its own normal under the airflow impact state, so that a gap is formed between the first gunnery unit 11 and the second gunnery unit 12 for airflow to pass through.

[0063] In current construction practices, blasting blankets are typically made from woven waste tires. Several blanket units are usually spliced ​​together, and then steel wire is inserted into the tires to secure the edges. The assembled blanket is then placed over the blasting location. After blasting, the explosive gases expand rapidly, generating a shock wave that propels rocks and creates flying debris. The explosive gases first impact the blanket. Due to the small contact area between the blanket and the steel wire, displacement occurs when the blanket is lifted by the impact. At this point, the pressure at the connection point between the blanket and the wire is extremely high, making the wire prone to breakage and the blanket easily torn. This creates weak points in the protection at the connection points of the blanket units, allowing debris to easily fly out. The protective effect is poor, and the blanket has a short lifespan, requiring frequent maintenance.

[0064] like Figure 1 and Figure 3 As shown, the gun shell connecting device 2 detachably connects two adjacent gun shell units together through the fixed base 21 and the connector 22, increasing the force-bearing area between the gun shell connecting device 2 and the gun shell unit. The gun shell is less likely to be damaged when it is impacted by the blasting gas. If the gun shell connecting device 2 breaks, only the gun shell connecting device 2 can be replaced, extending the service life of the gun shell and reducing the workload of gun shell maintenance. The detachable and splicable fixed-size gun shell units are convenient for production, transportation and assembly.

[0065] like Figure 2 and Figure 4 As shown, the connection points of two adjacent blasting units overlap on the plane facing the blasting location, which can effectively prevent debris from passing through the connection point, avoid weak protection areas, and improve safety.

[0066] like Figure 8 As shown, a gap is formed between two adjacent shell units to allow the blasting airflow to pass through. This can effectively block flying rocks while guiding the blasting airflow, reducing the impact force of the blasting airflow on the shell unit, and at the same time reducing the tension borne by the shell connecting device 2, thus extending the service life of the shell unit and the shell connecting device 2.

[0067] In one possible implementation, a fixing base 21 is disposed on the first surface of the first blasting unit 11, and a connector 22 is disposed on the second surface of the second blasting unit 12. The connector 22 is connected to the fixing base 21 so that a portion of the first surface overlaps a portion of the second surface.

[0068] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing base 21 is disposed on the first surface of the first shelling unit 11, and the connector 22 is disposed on the second surface of the second shelling unit 12. During specific installation, both the fixing base 21 and the connector 22 are disposed on the edge area of ​​the shelling surface. When the fixing base 21 and the connector 22 are connected, a portion of the first and second shelling surfaces overlap, so that a portion of the first shelling unit 11 and the second shelling unit 12 overlap on the plane facing the blasting position, so that the connection positions of the two adjacent shelling units overlap, effectively blocking flying stones and preventing debris from flying out from the connection position of the shelling units. The protection effect is good and the safety is high.

[0069] In one possible implementation, the fixing base 21 and the connector 22 are provided in a one-to-one correspondence.

[0070] It is understandable that the fixing base 21 and the connecting piece 22 of two adjacent gun units are connected in a one-to-one correspondence, and thus the fixing base 21 and the connecting piece 22 of two adjacent gun units are set in a one-to-one correspondence.

[0071] In one possible implementation, the fixing base 21 is disposed on the edge region of the first gun-bearing unit 11 near the second gun-bearing unit 12, and the connecting member 22 is disposed on the edge region of the second gun-bearing unit 12 near the first gun-bearing unit 11.

[0072] It is understandable that the fixing base 21 and the connector 22 are both located at the edge of the gun cover unit. When the fixing base 21 and the connector 22 are connected, it is sufficient to ensure that there is an overlapping area between the first gun cover unit 11 and the second gun cover unit 12. The width of this overlapping area is generally between 5cm and 20cm. If the overlapping area is too wide, it will reduce the coverage area after the gun cover units are spliced. When large-area protection is required, it may increase the number of gun cover units and increase the cost of transportation and assembly.

[0073] In one possible implementation, the fixing base 21 includes:

[0074] Base 211;

[0075] Groove 212 is used to accommodate connector 22;

[0076] The slide groove 214 is formed on the end face of the base 211 and communicates with the groove 212, so that the connector 22 can slide along the direction of the groove 212;

[0077] Unlocking hole 213 is located at one end of slide groove 214 and is used for connector 22 to be inserted into or disengaged from groove 212;

[0078] The locking hole 215 is located at the other end of the slide groove 214 and is used to limit the position of the connector 22 sliding along the direction of the groove 212.

[0079] like Figure 5 , Figure 6 , Figure 10 , Figure 11 and Figure 12 As shown, the fixing seat 21 is set on the first gun shell unit 11, specifically at the edge position along the edge line of the first shell surface of the first gun shell unit 11. The number of fixing seats 21 set along the edge line of the first gun shell unit 11 is at least two. The distance between two adjacent fixing seats 21 is preferably 10cm to 50cm. Connecting two adjacent gun shell units at multiple points can improve the stability of the gun shell connection.

[0080] The base 211 is detachably mounted on the gun shell unit, typically secured by bolts. It is understood that the base 211 has through holes for the bolts to pass through, and the bolts pass through these holes to secure the base 211 to the gun shell unit. Preferably, the bolts pass through the through holes of the base 211 and the gun shell unit, with the other end of the bolt secured by a nut. The base 211 is then locked to the gun shell unit by two bolts located at both ends of the base 211.

[0081] In a specific implementation, a portion of the connector 22 can be inserted into the groove 212 through the unlocking hole 213. The width of the slide 214 is smaller than the width of the groove 212. The base 211 walls on both sides of the slide 214 can restrict a portion of the connector 22 within the groove 212, allowing the connector 21 to slide along the direction of the groove 212 through the slide 214.

[0082] In specific implementation, such as Figure 10 and Figure 12 As shown, when the connector 21 moves to the limit position of the groove 212, that is, when the connector 21 slides to the locking hole 215, the connection between the connector 21 and the fixed seat 21 is completed. It can be understood that when the gun shell is impacted by the blasting gas, the gun shell unit is mainly subjected to the impact force outward along its own normal direction. The gun shell unit moves outward along its own normal direction and generates displacement. The gun shell connecting device 2 between two adjacent gun shell units is subjected to tension. Under the drive of the adjacent gun shell units, the connector 21 is always located in the position of the locking hole 215.

[0083] The present invention provides another embodiment, such as Figure 13 As shown, in Embodiment 2, the locking hole 215 is located at the bend of one end of the slide groove 214. Compared with Embodiment 1, when the connector 22 slides to the position of the locking hole 215 in Embodiment 2, the position of the connector 22 can be restricted by the locking hole 215, so that the connector 22 cannot move along the slide groove 214. Compared with Embodiment 1, which is locked by the explosive gas impact cannon unit, the locking method of Embodiment 2 is more secure and stable.

[0084] Understandably, when disassembling the two gun-bearing units, the connector 21 is slid to another extreme position, that is, the connector 21 is slid to the unlocking hole 213, and the connector 21 can be disengaged from the groove 212, thereby realizing the separation of the fixing seat 21 and the connector 22.

[0085] like Figure 5 and Figure 7 As shown, in one possible implementation, the connector 22 includes:

[0086] Connecting rod 221, one end of which is connected to the second gunnery unit 12;

[0087] The limiting block 222 is connected to the other end of the connecting rod 221.

[0088] The connecting rod 221 is detachably mounted on the gun bearing unit, typically secured by bolts. It is understood that the connecting rod 221 has a through hole for the bolt to pass through, and the bolt passes through the through hole to secure the connecting rod 221 to the gun bearing unit. Preferably, the bolt passes through the through hole of the connecting rod 221 and the gun bearing unit, and the other end of the bolt is secured by a nut. The connecting rod 221 is then locked to the gun bearing unit by two bolts located at both ends of the connecting rod 221.

[0089] It is understandable that, such as Figure 10 , Figure 11 and Figure 12 As shown, the width of the connecting rod 211 is less than the width of the slide groove 214, and the width of the limiting block 222 is greater than the width of the slide groove 214 and less than the width of the groove 212, so that the limiting block 222 can slide within the groove 212; at the same time, the width of the limiting block 222 is less than the width of the unlocking hole 213 and greater than the width of the locking hole 215, so that when the limiting block 222 slides to the unlocking hole 213, it can pass through the unlocking hole 213, and when the limiting block 222 slides to the locking hole 215, it is still restricted within the groove 212.

[0090] In one possible implementation, the first shot unit 11 and the second shot unit 12 are elastically connected along the direction normal to the second shot unit 12 itself.

[0091] In one possible implementation, the connector 22 further includes:

[0092] The elastic element 223 is used to make the fixed seat 21 and the connecting element 22 elastically connected in the direction of normal to the second gun unit 12 itself.

[0093] like Figure 4 and Figure 8 As shown, the elastic element 223 makes the fixed base 21 and the connecting element 22 elastically connected along the normal direction of the second gun shell unit 12. That is, when the blasting gas impacts, the first gun shell unit 11 and the second gun shell unit 12 are elastically connected along the movement direction of the second gun shell unit 12. The elastic element 223 makes the gun shell unit absorb part of the impact force generated by the blasting gas, which further weakens the impact of the shock wave on the gun shell unit, further reduces the wear of the gun shell unit, and extends the service life of the gun shell unit.

[0094] Meanwhile, when the thickness of the limiting block 222 is less than the height of the groove 212, the height of the gap between the first shelling unit 11 and the second shelling unit 12 can be adjusted by the elastic element 223. When the second shelling unit 12 is subjected to the blasting gas, the second shelling unit 12 moves away from the blasting position along its own normal direction. The first shelling unit 11 and the second shelling unit 12 are connected by the shelling connection device 2. At this time, the elastic element 223 is squeezed, which increases the height of the gap between the first shelling unit 11 and the second shelling unit 12, achieving the function of diversion. Part of the blasting gas is discharged outward from the gap between the first shelling unit 11 and the second shelling unit 12, reducing the impact of the blasting gas on the shelling unit and extending the service life of the shelling unit.

[0095] In one possible implementation method provided in this application, such as Figure 5 , Figure 8 and Figure 9 In the first embodiment shown, the elastic element 223 is sleeved on the connecting rod 221. When the connecting element 22 and the fixed seat 21 are connected, the elastic element 223 is located in the groove 212, and one end of the elastic element 223 abuts against the inner wall of the groove 212, while the other end of the elastic element 223 abuts against the limiting block 222.

[0096] In practice, before blasting, such as Figure 4 As shown, the elastic element 223 presses against the limiting block 222 against the upper surface of the groove 212, and the other end of the elastic element 223 abuts against the lower surface of the groove 212, making the second firing unit 12 closer to the first firing unit 11, at which time the gap between the two is small. It can be understood that the width of the elastic element 223 is less than the width of the groove 212 and greater than the width of the locking hole 215. When the connector 22 and the fixing seat 21 are connected, the elastic element 223 always remains inside the groove 212. After the blast, due to the impact of the blast gas, the shell-bearing unit moves outward along its normal direction. The airflow passes through the connecting gap between several shell-bearing units. Under the impact of the airflow, the second shell-bearing unit 12 moves, causing the connecting rod 221 to move away from the fixed seat 21. The limiting block 222 squeezes the elastic element 223, increasing the length of the connecting rod 221 exposed above the fixed seat 21. This increases the height of the gap between the first shell-bearing unit 11 and the second shell-bearing unit 12, allowing more airflow to pass through and further reducing the impact force of the blast on the shell-bearing unit.

[0097] Meanwhile, the elastic element 223 can automatically adjust the gap height through which the airflow passes according to the impact force of the blasting airflow on the gun casing unit, so as to meet the need for automatic drainage and adjustment of exhaust flow.

[0098] like Figure 11As shown, a gasket 224 can also be provided. The gasket 224 is sleeved on the connecting rod 221 and located at the end of the elastic member 223 away from the limiting block 222. Under the compression of the elastic member 223, the gasket 224 and the limiting block 222 abut against the upper and lower surfaces of the groove 212 respectively, avoiding direct contact between the elastic member 223 and the groove 212, reducing the wear of the elastic member 223 on the inner wall of the groove 212, and at the same time, the contact between the gasket 224 and the groove 212 is more stable, preventing the elastic member 223 from deforming under force and detaching from the groove 212. It is also more convenient to assemble the connecting member 22 and the fixing seat 21.

[0099] In another possible implementation provided in this application, such as Figure 14 and Figure 15 In the third embodiment shown, one end of the elastic member 223 is connected to the connecting rod 221, and the other end of the elastic member 223 is connected to the limiting block 222. The elastic member 223 is located in the groove 212 or can be inserted into the sliding groove 214.

[0100] In practice, the connecting rod 221 and the limiting block 222 can be directly connected by the elastic element 223. When there is no explosion, the elastic element 223 is located inside the groove 212. Under the impact of the explosion airflow, the second gun-bearing unit 12 drives the connecting rod 221 to move, and then the elastic element 223 is subjected to tension and deforms, so that part of the elastic element 223 passes through the locking hole 215. The limiting block is always located inside the groove 212, so that the height of the gap between the first gun-bearing unit 11 and the second gun-bearing unit 12 increases, allowing more airflow to pass through, and further reducing the impact force of the explosion on the gun-bearing unit. It is understood that the width of the elastic element 223 is less than the width of the groove 212 and slightly larger than the width of the locking hole 215. When the connector 22 and the fixing seat 21 are connected, the elastic element 223 can deform under a certain tensile force, causing a portion of the elastic element 223 to be smaller than the width of the locking hole 215, so that this portion of the elastic element 223 can pass through the locking hole 215, thereby increasing the height of the gap between the first firing unit 11 and the second firing unit 12. It is understood that this embodiment does not use a gasket 224.

[0101] A detachable gun cover includes a gun cover connecting device 2 as described above, and further includes a plurality of first gun cover units 11 and second gun cover units 12 that are detachably connected by the gun cover connecting device.

[0102] Understandable, Figure 1 The diagram shows the connection structure of two gun shell units via gun shell connecting device 2. However, in actual implementation, the number of gun shell units that need to be spliced ​​is generally greater than two. Figure 16A schematic diagram of the connection structure of four gun shell units through gun shell connecting device 2 is shown. By analogy, schematic diagrams of the connection structures of six gun shell units, eight gun shell units, and so on can be obtained.

[0103] like Figure 16 As shown, several fixing seats 21 and connecting parts 22 need to be set in the edge area of ​​two adjacent gun shell units. The fixing seats 21 and connecting parts 22 of two adjacent gun shell units are connected one-to-one, so that the two adjacent gun shell units can achieve multi-point connection and more uniform force distribution.

[0104] like Figure 17 and Figure 18 As shown, preferably, several fixing seats 21 are arranged along the two adjacent edge lines of the first surface of the gun shell unit, and several connecting pieces 22 are arranged along the other two edge lines of the second surface of the gun shell unit. By fixing the spacing of the fixing seats 21 and the connecting pieces 22, and the size of the gun shell unit, it is possible to detachably splice several gun shell units together through the gun shell connecting device 2.

[0105] like Figure 16 As shown, preferably, the dimensions of several blasting units are fixed, and the shape of the blasting units can be polygonal, such as triangles, squares, rectangles, hexagons, etc., as long as the sides of two adjacent blasting units are of equal length and their shapes can be spliced ​​together. It is understandable that square blasting units are the most convenient to assemble and can meet the needs of different explosion-proof construction areas.

[0106] Meanwhile, standard-sized blasting blanket units are easier to produce, process and transport, and easier to lay and assemble. They can meet the blasting protection needs of different areas, and each blasting blanket unit is lightweight and easy to lay. The blasting blanket units connected by the blasting blanket connecting device 2 have low wear and wide adaptability, and can adapt to the laying needs of different terrains.
