Description

Technical Field

[0001] This utility model relates to the field of dynamic compaction device technology, specifically a dynamic compaction device for airport runway grading. Background Technology

[0002] The foundation soil in the area where the airport runway is located may have problems, such as collapsible loess or weak foundation, which require dynamic compaction to improve the bearing capacity and stability of the foundation.

[0003] Patent CN214497094U discloses an energy-saving dynamic compaction device for airport runway construction, specifically relating to the field of dynamic compaction technology. It includes a support frame with a dynamic compaction mechanism inside. The mechanism includes a limiting plate fixedly mounted on the top of the support frame's inner cavity, with two guide holes on its top surface. This patent utilizes a dynamic compaction mechanism where, during the downward displacement of the reinforcing block, the hook is pressed against the top of the connecting rod due to pressure. The first hydraulic rod continues downward, causing the hook to engage with the bottom of the connecting rod, facilitating the upward movement of the compaction head. The distance between the compaction head and the impact block depends on the extension and retraction of the first hydraulic rod; a larger distance results in greater impact force, increasing compaction efficiency. The design is simple, compact, and highly operable. The impact force of the compaction head is adjustable, providing stable compaction results and ease of use.

[0004] As shown in the above technology, during the dynamic compaction process of airport runways, the hammer plate is directly subjected to heavy pressure for a long time, resulting in high wear. Once the device enters a stable working state, it needs to be replaced regularly. In addition, the dynamic compaction device itself is heavy, and if it shakes and separates during transfer between airports, it will have serious consequences. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an airport runway leveling and compaction device. It solves the problems of the hammer plate bearing heavy pressure for a long time, resulting in high wear and tear, the need for regular replacement of the device once it reaches a stable working state, and the serious consequences that would occur if the compaction device shakes and separates during transfer between airports due to its weight.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an airport runway leveling and compaction device, comprising:

[0007] The working housing has a guide groove block fixedly connected to one side;

[0008] A rammer assembly, one side of which is slidably connected to the interior of the working housing, is used to perform gravity hammering on an airport runway using relevant rammer parts.

[0009] A protective component, one side of which is fixedly connected to the surface of the working housing, is used to provide effective protection during operation and relocation.

[0010] Preferably, the ramming hammer assembly includes a gravity block that is slidably connected to the inner wall of the working housing, the surface of the gravity block is provided with a connecting groove, and the bottom of the gravity block is provided with a circular groove.

[0011] Preferably, a connector plate is fixedly connected to one side of the inner wall of the circular groove, and a slot is provided on the surface of the connector plate. An elastic ball is fixedly connected to one side of the inner wall of the circular groove. A connector post is movably connected to the inner wall of the circular groove. A counterweight plate is fixedly connected to the bottom end of the connector post. Vertical groove plates are fixedly connected to both sides of the surface of the connector post, and screw rods are threaded onto the surface of the vertical groove plates.

[0012] Preferably, a stress plate is rotatably connected to the top of the gravity block, and a lifting ring is fixedly connected to the top of the stress plate.

[0013] Preferably, the protective component includes a connecting plate fixedly connected to the surface of the working housing, the surface of the connecting plate having a dovetail groove, the inner wall of the dovetail groove being movably connected to a dovetail block, and a protective plate being fixedly connected to one side of the dovetail block.

[0014] Preferably, limit slots are fixedly connected to both sides of the working shell surface, and synchronous folding plates are movably connected to the inner surface of the limit slots, with bolts penetrating the surface of the synchronous folding plates.

[0015] This utility model provides an airport runway grading and dynamic compaction device. Compared with the prior art, it has the following advantages:

[0016] 1. The airport runway grading and compaction device utilizes a tamping hammer assembly with a circular groove at the bottom of the gravity block. This, along with slots, connecting posts, and vertical groove plates, allows the connecting posts and the hammer plate to be directly inserted into the circular groove. The mechanism is then fixed by rotation. Once the vertical groove plate enters the circular groove, as long as it is not misaligned with the slot, the mechanism will not separate. Furthermore, the use of screw rods connected to the vertical groove plate further enhances the stability and reliability of the hammer plate after installation. The use of stress plates and lifting rings allows the stress plates to rotate automatically during external lifting, relieving stress caused by rope torsion and ensuring smooth lifting.

[0017] 2. The airport runway leveling and compaction device utilizes protective components. During transportation, the synchronous folding plate can be directly inserted into the connecting groove and the limiting groove, and the bolts further fix its position. This effectively avoids the shaking of the gravity block and the hammer plate caused by rapid start and stop during transportation, further improving the reliability and safety of the device operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 This utility model provides two technical solutions:

[0028] Example 1: An airport runway leveling and compaction device, comprising:

[0029] The working housing 1 has a guide groove block 2 fixedly connected to one side;

[0030] The rammer assembly 3 has one side slidably connected to the inside of the working housing 1. The rammer assembly 3 is used to perform gravity hammering on the airport runway using relevant rammer parts.

[0031] The protective component 4 is fixedly connected to the surface of the working shell 1 on one side. The protective component 4 is used to effectively protect the device during operation and relocation. With the setting of the hammer assembly 3, a circular groove 33 is set at the bottom of the gravity block 31. At the same time, with the slot 35, the connecting post 37 and the vertical groove plate 38, the connecting post 37 and the hammer plate 39 can be directly inserted into the circular groove 33 as a whole. Then, the relevant mechanism is fixed by rotation. After the vertical groove plate 38 enters the circular groove 33, as long as it is not separated from the slot 35, the relevant mechanism will not be separated. In addition, the screw rod 312 is connected to the vertical groove plate 38, which can further improve the stability and reliability of the hammer plate 39 after installation. With the setting of the stress plate 310 and the lifting ring 311, when the external lifting device lifts it, the stress plate 310 can rotate on its own to release the stress generated by the rope torsion, and the lifting rope can always remain in a smooth state.

[0032] Example 2 differs from Example 1 primarily in that: an airport runway leveling and compaction device includes a tamping hammer assembly 3 comprising a gravity block 31 slidably connected to the inner wall of the working housing 1. The surface of the gravity block 31 has a connecting groove 32, and the bottom of the gravity block 31 has a circular groove 33. A connecting plate 34 is fixedly connected to one side of the inner wall of the circular groove 33. A slot 35 is formed on the surface of the connecting plate 34. An elastic ball 36 is fixedly connected to one side of the inner wall of the circular groove 33. A connecting post 37 is movably connected to the inner wall of the circular groove 33. A hammer plate 39 is fixedly connected to the bottom end of the connecting post 37. Vertical groove plates 38 are fixedly connected to both sides of the surface of the connecting post 37. The grooves in the vertical groove plates 38 correspond to the elastic balls 36, and the vertical groove plates 38 themselves correspond to the slots 35. A screw rod 312 is threadedly connected to the surface of the vertical groove plates 38. A stress plate 310 is rotatably connected to the top of the gravity block 31, and a suspension rod is fixedly connected to the top of the stress plate 310. Ring 311, the protective component 4 includes a connecting plate 41 fixedly connected to the surface of the working shell 1. The surface of the connecting plate 41 is provided with a dovetail groove 42. A dovetail block 43 is movably connected to the inner wall of the dovetail groove 42. The thickness of the guide groove block 2 is less than the height of the dovetail block 43. A protective plate 44 is fixedly connected to one side of the dovetail block 43. Limiting groove blocks 45 are fixedly connected to both sides of the surface of the working shell 1. A synchronous folding plate 46 is movably connected to the inner surface of the limiting groove block 45. One side of the synchronous folding plate 46 is adapted to the connecting groove 32. A bolt 47 passes through the surface of the synchronous folding plate 46. With the setting of the protective component 4, when the device is transported, the synchronous folding plate 46 can be directly inserted into the connecting groove 32 and the limiting groove block 45, and the bolt 47 further fixes its position, effectively avoiding the shaking of the gravity block 31 and the counterweight plate 39 caused by rapid start and stop during transportation, and further improving the reliability and safety of the device operation.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the connecting pin 37 and screw rod 312 are connected and installed with the gravity block 31. The connecting pin 37 can be stably inserted into the circular groove 33. After the vertical groove plate 38 passes through the slot 35, the connecting pin 37 is rotated. When the surface of the vertical groove plate 38 engages with the elastic ball 36, a slight vibration occurs. At this time, the screw rod 312 is inserted through the connecting plate 34 and the vertical groove plate 38 and rotated to fix the screw rod 312 to the vertical groove plate 38. After fixing the gravity block 31, the lifting ring 311 is connected to the external lifting rope. The dovetail block 43 is inserted into the dovetail groove 42. The protective plate 44 isolates the stones splashed from the external construction site. The device performs normal tamping operation. When transferring the device, the synchronous folding plate 46 is inserted into the limiting groove 45 and the connecting groove 32, and then the rotating bolt 47 is inserted. The relative position of the gravity block 31 is fixed. Then the device is transferred. After the device finishes working, the device is restored.
