Description

Technical Field

[0001] The present invention belongs to the technical field of road repair, and in particular relates to a device and method for repairing bomb craters on a runway of an airport during wartime. Background Art

[0002] Airports are important strategic targets. Destroying airport runways can prevent aircraft from taking off and landing, thereby affecting the war situation. Therefore, after an attack, whether the runway craters can be quickly repaired in a short period of time to ensure that fighter jets can take off quickly is a guarantee of combat.

[0003] Traditional repair involves filling the crater with conventional concrete materials, which require an external power source for mixing and pouring. The repair steps are cumbersome and cannot be performed by one person alone. The equipment is relatively large and cannot meet airdrop requirements. Summary of the Invention

[0004] The embodiments of the present invention provide a wartime airport runway crater repair device and method, aiming to solve the technical problems that existing crater repair technology is complex and cannot be operated by one person, and the equipment is relatively large and cannot meet the needs of airdrop.

[0005] In a first aspect, an embodiment of the present invention provides a wartime airport runway crater repair device, comprising:

[0006] The container body is provided with a pull rod, and the container body is also provided with a safety device detachably connected to the pull rod;

[0007] a partition layer disposed in the container body, for dividing the space in the container body into a first accommodating chamber containing the first slurry and a second accommodating chamber containing the second slurry, wherein a first side of the partition layer is fixedly disposed on the inner wall of the container body, and a second side thereof abuts against the inner wall of the container body, the second side being opposite to the first side and fixedly connected to the bottom end of the pull rod, and the partition layer is a foldable member;

[0008] Two stirring assemblies, one of which extends into the first accommodating chamber, and the other extends into the second accommodating chamber;

[0009] The driving assembly includes two straps arranged on the outer periphery of the container body, and the top and bottom ends of the two straps are respectively provided with pull ropes, the pull ropes at the top ends are respectively connected to the top ends of the two stirring assemblies, and the pull ropes at the bottom ends are respectively connected to the bottom ends of the two stirring assemblies.

[0010] Compared to the prior art, the solution shown in the embodiment of the present application is simple in structure and easy to operate. It can be carried by hand or on the back by a pull handle. When it is moved to the crater to be repaired, the safety device can be removed and the pull handle can be pulled. The pull handle causes the separation layer to fold, and the first and second slurries on both sides of the separation layer come into contact. The two straps can then be pulled alternately. During the pulling process, the pull rope drives the stirring assembly to rotate. The rotation of the two stirring assemblies promotes the rapid mixing of the first slurry and the second paddle to form a mixed liquid that can be filled into the crater. The mixed liquid is then poured into the crater and allowed to solidify to complete the repair. The wartime airport runway crater repair equipment of the present invention has a simple structure and is easy to operate. It can be operated by one person without difficulty, reducing labor intensity. In addition, various structures and the first and second slurries are integrated into the container body, facilitating airdrop and transportation, meeting practical needs. The crater is repaired by mixing, pouring and solidifying the first and second slurries. The operation is short and the repair process is rapid, providing combat support.

[0025] A fixing plate is fixedly mounted on the top of the container body, and a second through hole corresponding to the first through hole is formed on the fixing plate;

[0026] The latches respectively pass through the first through hole and the second through hole and are plugged into each other.

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] Please also refer to Figures 1 to 6 The wartime airport runway crater repair equipment provided by the present invention is now described. The wartime airport runway crater repair equipment includes a container body 10, a partition layer 30, two stirring assemblies 40, and a driving assembly 50. The container body 10 is provided with a pull rod 11, and the container body 10 is also provided with a safety device 20 that is detachably connected to the pull rod 11; the partition layer 30 is provided in the container body 10, and is used to separate the space in the container body 10 into a first receiving chamber filled with a first slurry and a second receiving chamber filled with a second slurry. The first side of the partition layer 30 is fixed to the inner wall of the container body 10, and the second side is fixed to the container body. 10 abuts against the inner wall, the second side is the opposite side of the first side, and is fixed to the bottom end of the pull rod 11, and the partition layer 30 is a foldable component; one of the stirring components 40 extends into the first accommodating cavity, and the other stirring component 40 extends into the second accommodating cavity; the driving component 50 includes two straps 51 arranged on the outer periphery of the container body 10, and the top and bottom ends of the two straps 51 are respectively provided with pull ropes 52, the pull ropes 52 at the top are respectively connected to the top ends of the two stirring components 40, and the pull ropes 52 at the bottom are respectively connected to the bottom ends of the two stirring components 40.

[0052] It should be noted that both the first slurry and the second slurry are quick-setting chemical slurries, and specific examples include: (1) the first slurry is polyurethane and the second slurry is water glass; (2) the first slurry is water glass and the second slurry is calcium chloride. Other first slurries and second slurries with similar functions are applicable, and no further examples are given here. In addition, the drawings of this application illustrate that the first slurry and the second slurry are distributed left and right. However, in actual use, the partition layer 30 can also be separated horizontally from the middle, that is, the first slurry and the second slurry are distributed up and down, etc. In this case, the pulling direction of the pull rod becomes horizontal pulling.

[0053] Optionally, the partition layer 30 is a foldable component, and its folding form can be similar to a screen or a rolling shutter. As a modified embodiment, the partition layer 30 can also be a flexible plastic layer (its strength can overcome the impact force of the first and second slurries during transportation or airdrop), with a pull rope (which can be made of nylon or other materials) provided on the plastic layer. The safety device is a pull rope, which is fixed to the container body 10. The pull rope can extend in an "X", "Y", or "I" shape on the plastic layer. When the pull rope is pulled, a corresponding shaped breach is formed in the plastic layer. At this time, the plastic layer can be pulled to the top of the container body 10 via the pull rod 11 to prevent it from being drawn into the stirring assembly and affecting the stirring process. Alternatively, the pull rod can be left unpulled, allowing the first and second slurries to contact each other through the breach.

[0054] It is easy to understand that in order to facilitate the pouring of the first slurry and the second slurry after mixing, a pouring spout 13 can be provided on the container body 10, or a cutting guide groove 12 can be provided on the container body 10. After mixing, a tool is used to cut along the cutting guide groove 12 to form the pouring spout 13. Compared with directly setting the pouring spout 13 and sealing it with a threaded cap, which is easily stuck by the slurry, this structure can ensure that the mixed liquid is poured out smoothly.

[0055] Compared with the prior art, the wartime airport runway crater repair equipment provided by this embodiment can be recovered by carrying the container body 10 for movement. It can be carried by hand via the pull rod 11 or carried on the back via the shoulder strap 51. When it is moved to the crater that needs to be repaired, the safety device 20 can be removed and the pull rod 11 can be pulled. The pull rod 11 drives the partition layer 30 to fold. At this time, the first slurry and the second slurry on both sides of the partition layer 30 are in contact. Then, the two shoulder straps 51 can be pulled alternately. During the pulling process of the shoulder straps 51, the pulling rope 52 drives the stirring assembly 40 to rotate. The rotation of the two stirring assemblies 40 promotes the rapid mixing of the first slurry and the second paddle to generate a mixed liquid that can be filled in the crater. The mixed liquid is then poured into the crater. After it solidifies, the repair is completed. The wartime airport runway crater repairing equipment of the present invention has a simple structure and is easy to operate. It can be operated by one person without difficulty, thereby reducing labor intensity. In addition, various structures and the first slurry and the second slurry are integrated into the container body 10, which is convenient for airdrop transportation, etc., and meets actual needs. The crater repair is completed by mixing, pouring and solidifying the first slurry and the second slurry. The operation time is short and the repair process is rapid, providing combat support.

[0056] In some embodiments, an improved embodiment of the container body 10 can adopt the structure described below. Not shown in the figure, a locking buckle is provided on the side of the container body 10 facing the shoulder strap 51, and the two ends of the shoulder strap 51 are respectively connected to the locking buckle. When carrying the container body 10, the locking buckle fixes the two ends of the shoulder strap 51 for easy carrying; when stirring is required, the locking buckle is opened, the shoulder strap 51 is released from the container body 10, and the shoulder strap 51 can be pulled to drive the stirring assembly 40 for stirring. Optionally, the locking buckle can adopt the locking structure on the belt.

[0057] In some embodiments, an improved embodiment of the container body 10 can be as follows Figure 2 and Figure 5 The structure shown. Figure 2 and Figure 5 The bottom of the container body 10 is provided with an electric base 60, which includes a battery 61 and a stirring motor 62 electrically connected to the battery 61. The bottom of the stirring assembly 40 is provided with a driven gear 41 drivingly connected to the stirring motor 62. The electric base 60 is detachably connected to the container body 10. During actual use, one electric base 60 and multiple container bodies 10 can be airdropped at the same time, and multiple container bodies 10 share one electric base 60. By providing the electric base 60, the electric stirring process can be conveniently performed after the partition layer 30 is opened, replacing manual operation, not only improving the stirring effect, but also shortening the stirring time and reducing labor intensity.

[0058] It should be noted that when the stirring motor 62 is provided, the shoulder strap 51 may not be used during the stirring process. At this time, the shoulder strap 51 serves as a backup condition, that is, stirring is only performed by pulling the shoulder strap 51 when the stirring motor 62 is damaged, out of power, or not in use in the on-site environment.

[0059] Specifically, a roller 63 may be provided at the bottom of the electric base 60 . The roller 63 is electrically connected to the battery 61 . The battery 61 controls the rolling of the roller 63 to drive the container body 10 to move, thereby further facilitating the transportation of the container body 10 .

[0060] In some embodiments, a transmission method of the stirring assembly 40 and the electric base 60 can be as follows: Figure 2 and Figure 5 The structure shown. Figure 2 and Figure 5 The output shaft of the stirring motor 62 is provided with a driving gear 64. The motor base 60 is also provided with a matching assembly 70. The matching assembly 70 includes a slide, two fixed shafts 72, and two transmission gears 73. The slide is slidably connected to the motor base 60 along a first preset path, which is parallel to the horizontal direction. The two fixed shafts 72 are fixedly mounted at the ends of the slide. The two transmission gears 73 are respectively rotatably connected to the two fixed shafts 72. The transmission gears 73 are used to mesh with the driving gear 64 and the driven gear 41 respectively. When normally stored or transported or airdropped, the slide 71 is in an initial state. At this time, the transmission gears 73 are not in contact with the driving gear 64 or the driven gear 41. After the pull rod 11 is pulled to fold the partition layer 30, the first slurry and the second slurry are mixed. At this time, the slide can be pushed, causing the slide to drive the two transmission gears 73 to move. At this time, the transmission gears 73 are respectively meshed with the driving gear 64 and the driven gear 41. Turning on the drive motor can drive the stirring assembly 40 to rotate and achieve stirring.

[0061] Specifically, a pull ring 74 is provided at one end of the sliding seat 71 away from the fixed shaft 72, and the sliding seat 71 can be driven to move by pushing and pulling the pull ring 74, which is convenient for operation; in order to facilitate the fixation of the sliding seat 71, when the transmission gear 73 is spaced from the master and slave gears and the driven gear 41 respectively, second grooves 75 are provided on both sides of the sliding seat 71, and two support rods 65 are provided on the outer periphery of the electric base 60, and a torsion spring is connected between one end of each support rod 65 and the electric base 60, and the other end of the support rod 65 is pushed into the second groove 75. The sliding seat 71 can be fixed by the cooperation of the support rods 65 on both sides and the second grooves 75, so as to prevent the sliding seat 71 from automatically sliding into the driving gear 64 and the driven gear 41 to form a transmission connection during airdrop or transportation.

[0062] In some embodiments, a specific embodiment of the stirring assembly 40 can be as follows: Figures 1 to 2 The structure shown. Figures 1 to 2 The stirring assembly 40 includes a stirring shaft 42 and multiple stirring groups. The stirring shaft 42 is rotatably connected to the container body 10, and the axial direction of the stirring shaft 42 is parallel to the vertical direction. The multiple stirring groups are spaced apart along the axial direction of the stirring shaft 42. Each stirring group includes multiple blades evenly distributed along the axial direction of the stirring shaft 42, and the blades are arranged at an angle. When the pull rope 52 or the stirring motor 62 drives the stirring shaft 42 to rotate, the rotation of the stirring shaft 42 drives the multiple blades to rotate. The multiple blades are evenly distributed along the axial direction of the stirring shaft 42, allowing stirring to be performed at different positions up and down within the container body 10. The inclined arrangement of the blades can improve stirring efficiency, which is beneficial for improving the quality of the mixed liquid formed after the first slurry and the second slurry are mixed, thereby ensuring the strength of the repaired crater.

[0063] In some embodiments, an improved embodiment of the stirring assembly 40 can be as follows Figure 2 and Figure 4 The structure shown. Figure 2 and Figure 4 The top and bottom ends of the stirring shaft 42 protrude from the container body 10, respectively. A rolling wheel 44 is fixed to each end of the stirring shaft 42. The outer circumference of the rolling wheel 44 is provided with a first groove 45, and the bottom surface of the first groove 45 is provided with a protruding puncture 46. The pull rope 52 is placed in the first groove 45, and the puncture 46 penetrates the gap of the pull rope 52. When the pull rope 52 cooperates with the rolling wheel 44, the puncture 46 can penetrate the gap of the pull rope 52. As a result, when the pull rope 52 is pulled, it can effectively prevent slipping, ensuring that the pulling of the pull rope 52 drives the stirring assembly 40 to rotate, thereby achieving stirring.

[0064] As a modified embodiment, the stirring shaft 42 may not extend out of the container body 10, that is, the stirring shaft 42 is inside the container body 10 and is rotatably connected to the container body 10. In the process of rotating stirring, a driving mechanism can be set on the container body 10 to drive the stirring shaft 42 to rotate using the principle of magnetic coupling, thereby avoiding the stirring shaft 42 extending out of the container body 10 and making it inconvenient to seal.

[0065] In some embodiments, an improved embodiment of the container body 10 can be as follows Figure 6 The structure shown. Figure 6The outer periphery of the container body 10 is provided with a binding groove 14. The container body 10 also includes a strap 15 that is bound to the outer periphery of the container body 10 along the extending direction of the binding groove 14. The strap 15 is located in the binding groove 14 and forms an air cavity therein. In the initial state, the air cavity is filled with gas so that the strap 15 protrudes from the outer surface of the container body 10. When the container body 10 is not in use, the strap 15 is bound to the outer periphery of the container body 10 and is filled with gas. In this case, the air in the strap 15 can play a certain protective role for the container body 10, buffering a certain amount of impact force during a collision and preventing the container body 10 from being damaged or leaking slurry. After the crater is repaired, the gas in the strap 15 can be released and used as a conventional rope to bind the used container body 10 and other tools for easy retreat.

[0066] It should be noted that an air nozzle may be provided on the strap 15 to facilitate inflation and deflation; or an air nozzle may not be provided, and the strap 15 is in an inflated state after production, and can be punctured with a hard object when deflation is required.

[0067] In some embodiments, a specific embodiment of the pull rod 11 can be as follows: Figures 1 to 6 The structure shown. Figures 1 to 6 The container body 10 has a rectangular cross-section, and the partition layer 30 extends along the diagonal line of the rectangle. The pull rod 11 includes two mutually parallel fixed rods 111 and a handle 112 connected to the top of the two fixed rods 111. The fixed rods 111 slide with the container body 10. The bottom ends of the fixed rods 111 are fixed to the bottom edge of the partition layer 30 and are used to pull the partition layer 30 to fold in the vertical direction. The partition layer 30 is arranged along the docking line to increase the contact surface between the first slurry and the second slurry for rapid mixing and reaction. The two fixed rods 111 on the pull rod 11 can be arranged on the partition layer 30 in a diagonal direction so that when the partition layer 30 is closed, it abuts against the bottom of the partition layer 30 to prevent the first slurry and the second slurry from contacting each other, and the handle 112 facilitates pulling the fixed rods 111.

[0068] Optionally, the container body 10 may be made of plastic material, which is easy to store, prevents the first slurry and the second slurry from deteriorating, and is lightweight. The capacity of the container body 10 may be 20L to 40L.

[0069] Specifically, a rubber strip 16 is provided at the bottom of the container body 10. This strip 16 also extends along the docking line of the container body 10. That is, when the partition layer 30 is closed, the bottom end of the fixing rod 111 drives the bottom side of the partition layer 30 to abut against the rubber strip 16. The elastic deformation of the rubber strip 16 ensures the sealing of the first and second accommodating cavities. The rubber strip 16 can be directly provided on the bottom surface of the container body 10 or embedded in the bottom surface of the container body 10.

[0070] In some embodiments, a specific implementation of the above-mentioned safety device 20 can be as follows: Figure 3 The structure shown. Figure 3 The safety device 20 is provided with two fixed rods 111, and the fixed rod 111 is provided with a first through hole. The safety device 20 includes a fixed plate 21 and a latch 22. The fixed plate 21 is fixed to the top of the container body 10, and the fixed plate 21 is provided with a second through hole corresponding to the first through hole; the latch 22 passes through the first through hole and the second through hole respectively, and plugs in and fits. When the container body 10 is disassembled during transportation and is in the installation state, the pull rod 11 cannot be pulled at this time, which can ensure that the bottom side of the separation layer 30 is pulled against the bottom of the container body 10 to prevent the first slurry and the second slurry from mixing; when repair is needed, the latch 22 is pulled out, and the pull rod 11 can be pulled at this time. The pull rod 11 drives the separation layer 30 to fold so that the first slurry and the second slurry are mixed. It is fixed by the latch 22, which is convenient to operate and has a simple structure. It can respond quickly during the crater repair process.

[0071] In some embodiments, an improved embodiment of the above-mentioned wartime airport runway crater repair equipment can be implemented as follows: Figure 1 The structure shown. Figure 1 The wartime airport runway crater repair equipment also includes an equipment box 80. Optionally, the equipment box 80 can be directly fixed to the outer periphery of the container body 10, or it can be used in combination with the container body 10 without being connected to the container body 10. The equipment box 80 can contain necessary tools such as a saber, leveling tools, an angle grinder, and a nail gun. When pouring the mixed liquid, a pouring port 13 needs to be cut on the container body 10, and the top surface needs to be polished after the mixed liquid is poured. Placing the necessary tools in the equipment box 80 facilitates crater repair operations.

[0072] During the specific repair process, when the equipment box 80 is fixed on the container body 10, it is detachably connected to the container body 10. One equipment box 80 can be airdropped with multiple container bodies 10. Combined with the above description of the electric base 60, the repair construction of the same batch can use one equipment box 80, one electric base 60, and multiple container bodies 10, which reduces the transfer load and facilitates airdrop, transportation and other operations.

[0073] Based on the same inventive concept, an embodiment of the present application further provides a method for repairing a crater on a runway during wartime, which is implemented using the above-mentioned equipment for repairing a crater on a runway during wartime, and includes the following steps:

[0074] S10: driving steel nails into the inner wall of the crater to be repaired, with a portion of the steel nails being driven into the inner wall of the crater and another portion protruding from the inner wall of the crater, and the steel nails being evenly distributed on the inner wall of the crater;

[0075] S20: Remove the safety device 20 and pull the pull rod 11 to fold the partition layer 30 so that the first accommodating cavity and the second accommodating cavity are connected;

[0076] S30: Alternately pull the two straps 51, and the pull rope 52 drives the two stirring components 40 to rotate back and forth, stirring the first slurry and the second slurry to form a filling liquid;

[0077] S40: Pour the filling liquid into the pit to be repaired and overflow the ground to a preset height;

[0078] S50: After the filling liquid solidifies, it is polished and leveled.

[0079] Compared with the prior art, the wartime airport runway crater repair method provided in this embodiment can achieve rapid mixing of the first slurry and the second slurry by using the above-mentioned wartime airport runway crater repair equipment. The repair equipment has a simple structure and high robustness, and is suitable for battlefield environments; it is highly operable, and the repair process does not require long-term training and can be used by a single person; the emergency repair speed is fast, and rapid recovery can be achieved; the equipment and materials can be airdropped, and there are no requirements for land transportation lines, which is suitable for war zone operations; and during the repair process, the steel nail partially protrudes from the crater, which can prevent the mixed liquid from slipping after pouring, thereby improving the repair effect.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
