Description

Technical Field

[0001] This utility model relates to the field of airport maintenance equipment technology, and in particular to a filling and compaction device for rapid repair of airport runways. Background Technology

[0002] Airport runways are core infrastructure for ensuring flight safety. During their service life, their surfaces inevitably develop cracks and damage due to the impact of aircraft takeoffs and landings, heavy loads, and changes in ambient temperature.

[0003] To ensure the continued safe operation of the runway, these defects must be repaired in a timely and rapid manner. In the repair work, filling and compaction are the two most critical processes.

[0004] One existing repair method involves using separate equipment for different functions. For example, workers first use a filling device to fill the material, and then use a separate compaction device to compact it.

[0005] This work mode, which separates processes, not only requires two independent sets of equipment, but also involves cumbersome procedures, time-consuming connections between processes, and low overall repair efficiency, making it difficult to meet the strict time requirements for rapid repair of airport runways.

[0006] To improve efficiency, large-scale repair equipment that integrates filling and compaction functions has emerged. However, while such integrated equipment is highly efficient in dealing with long-distance, continuous cracks, its large structure and poor mobility make it severely inflexible when dealing with common, scattered, small-scale, or corner damage points on airport runways.

[0007] In summary, existing technologies for airport runway repair present a contradiction between operational efficiency and operational flexibility. Separate equipment offers some flexibility but suffers from low efficiency, while integrated equipment, although highly efficient, lacks sufficient flexibility.

[0008] Therefore, this utility model proposes a filling and compaction device for rapid repair of airport runways to overcome the shortcomings of the prior art. Utility Model Content

[0009] In view of the shortcomings of existing airport runway repair equipment, which make it difficult to balance operational flexibility and efficiency, specifically, the separate equipment leads to disjointed processes and long repair cycles, while the integrated large equipment has a bulky structure and is difficult to flexibly deal with scattered or small-scale edge and corner damage on the runway, this utility model aims to provide an airport runway rapid repair filling and compaction device with an improved structure and modular combination design that can effectively solve the above problems.

[0010] This utility model provides a filling and compaction device for rapid repair of airport runways, including: a support frame, a housing; and a storage bin, a discharge port, and a pressure roller column disposed on the support frame and disposed inside the housing.

[0011] The top of the support frame is fixedly connected to a storage bin, and the bottom of the support frame is fixedly connected to a discharge port. The storage bin and the discharge port are connected to each other to realize the storage and diversion of repair materials. The inside of the shell is rotatably connected to a pressure roller column to compact the laid material.

[0012] Furthermore, the bracket and the shell are combined through a specific limiting fit structure: the bracket has limiting grooves on both the front and rear sides, and the shell has bosses fixedly connected to both the front and rear sides. The outer wall of the boss matches the inner wall of the limiting groove and is fixed by connectors, so that the filling part and the compaction part can be combined into a whole for joint repair, or disassembled into independent units for decentralized operation.

[0013] Preferably, the bottom of the support is also provided with a leveling mechanism, specifically including a telescopic rod and a push plate. The telescopic rod is fixedly connected to the bottom of the support, and the push plate is fixedly connected to the bottom end of the telescopic rod. The telescopic rod is used to adjust the height of the push plate to adapt to different ground undulations.

[0014] Preferably, the bottom structure of the push plate is specially designed, with one side of its bottom surface being arc-shaped to smoothly cut into the accumulated repair material, and the rear part of its bottom surface being flat to smooth the surface of the material after cutting in, thereby ensuring the flatness of the repair surface.

[0015] Preferably, the bottom sides of the bracket are rotatably connected to a rotating shaft, and the front and rear ends of the rotating shaft are rotatably connected to wheels. The wheels cooperate with the rotating shaft to realize the movement and steering functions of the device.

[0016] Preferably, the top of the support is provided with a first power control system, including a power box and a control terminal. The power box is used to provide power to the filling and walking mechanism, and the control terminal is used to receive operation commands and provide feedback on the equipment status.

[0017] Preferably, a second power control system is provided on the top of the housing, including a second power box and a second control terminal. The second power box is used to drive the pressure roller to rotate, and the second control terminal is used to control the operation of the compaction mechanism.

[0018] Preferably, in order to achieve automated linkage in the combined mode, the second control terminal and the first control terminal establish a wireless communication connection, so that the compaction action at the rear can respond synchronously according to the filling action signal at the front.

[0019] Preferably, a support base is fixedly connected to the bottom of the housing. The support base extends vertically downward to provide independent parking support for the compaction device after it is separated from the support, thus preventing the equipment from tipping over.

[0020] Preferably, a handrail is fixedly connected to the side of the housing, and a groove is opened on the outer wall of the handrail. A switch button is embedded in and fixedly connected to the groove. This design allows the operator to push the compaction device independently by using the handrail and to directly control the start and stop of the power by using the switch button.

[0021] Preferably, the top of the storage bin is fixedly connected to a feed inlet to facilitate workers to inject repair materials into the bin.

[0022] This utility model has the following beneficial effects: 1. This utility model solves the problems of low work efficiency or lack of flexibility caused by the single function and separation of processes in the existing repair equipment by designing the equipment as a modular structure of filling device and compaction device, and by using boss and limiting groove to achieve detachable combination connection. It achieves a highly efficient repair effect that can realize both continuous operation of filling, leveling and compaction and independent and flexible operation of the two parts.

[0023] 2. This utility model solves the problem of uneven material surface after filling by setting a leveling mechanism with a telescopic rod and a push plate at the bottom of the filling device. It achieves high-precision leveling immediately after material filling, providing a flat foundation for subsequent compaction and significantly improving the quality and efficiency of repair.

[0024] 3. This utility model solves the problem of asynchronous actions between the two parts during combined operations by setting up a first power system, a first control terminal, a second power system, and a second control terminal, and enabling the two control terminals to achieve wireless communication linkage. This achieves a close connection and coordinated action between the filling and compaction operations, thereby realizing a continuous, fast, and efficient repair process. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example: Please refer to Figures 1 to 4 This utility model provides a filling and compaction device for rapid repair of airport runways, which aims to solve the problems of single function of existing repair equipment leading to process separation, low work efficiency, or poor flexibility of integrated equipment.

[0029] like Figure 1 and Figure 2 As shown, a rapid repair filling and compaction device for airport runways includes a support 1 and a housing 2. The support 1 is used to support the filling and leveling mechanism, and the housing 2 is used to support the compaction mechanism. The support 1 and the housing 2 can be combined or separated through a detachable connection structure. Specifically, the support 1 has a limiting groove 18 on the right side of both the front and rear sides, and the housing 2 has a boss 17 fixedly connected to the left side of both the front and rear sides. The outer wall of the boss 17 fits into the inner wall of the limiting groove 18 and is fixed by a connector. This structure allows the filling device and the compaction device to be combined for integrated continuous operation or separated for independent operation.

[0030] As the core component of the filling mechanism, a storage bin 5 is fixedly connected to the top right side of the support 1. A feed inlet 6 is fixedly connected to the top of the storage bin 5. Repair material is injected into the storage bin 5 through the feed inlet 6. A discharge outlet 19 is fixedly connected to the bottom of the support 1. The storage bin 5 is connected to the discharge outlet 19. The material stored in the storage bin 5 is filled into the gap through the discharge outlet 19. As the core component of the compaction mechanism, a pressure roller 13 is rotatably connected inside the shell 2. The pressure roller 13 compacts the filled surface.

[0031] Please refer to Figure 2The bottom of the bracket 1 is fixedly connected to two telescopic rods 9, and the bottom of each telescopic rod 9 is fixedly connected to the same push plate 10. The telescopic rods 9 are extended or retracted in a controlled manner to adjust the working state of the push plate 10. The push plate 10 is used to smooth the filled surface. The bottom left side of the push plate 10 is arc-shaped, and its rear part is flat. The arc-shaped end is convenient for cutting into the filling material, and the flat end is responsible for smoothing the surface of the filling material, which ensures the efficiency and accuracy of the smoothing operation.

[0032] The bottom left and right sides of the support 1 are rotatably connected to a rotating shaft 3, and the front and rear sides of the rotating shaft 3 are rotatably connected to wheels 4. The rotating shaft 3 is driven by a motor to rotate, which in turn drives the device to turn. The wheels 4 are used to move the device. The top left side of the support 1 is fixedly connected to a power box 7, which is used to provide power to the filling device. The top of the power box 7 is fixedly connected to a control terminal 8, which is used to receive wireless control from the staff. At the same time, the top of the control terminal 8 is fixedly connected to an indicator light, which can reflect the connection and start / stop status of the device.

[0033] A power box 21 is fixedly connected to the top rear side of the housing 2. The power box 211 is used to provide power to the pressure roller device. A control terminal 22 is fixedly connected to the top front side of the housing 2. The control terminal 22 can receive signals transmitted by the control terminal 8 to realize the linkage between the pressure roller device and the filling device, and ensure the continuity of filling and compaction operations. A vibration damping structure is provided at the connection between the housing 2 and the pressure roller column 13 to reduce the vibration impact of the pressure roller column 13 on the housing 2 when it is working.

[0034] In a preferred embodiment, in order to provide stable support and prevent the device from tipping over when the compaction device is not in operation or when it is stored separately from the filling device, two support seats 14 are fixedly connected to the bottom right side of the housing 2. The support seats 14 extend vertically downward and their bottom ends contact the ground, providing stable support for the parking of the pressure roller device when it is not in operation.

[0035] As another preferred embodiment, in order to facilitate manual pushing and control of the separated compaction device by the operator and flexible operation in independent operation mode, a handle 15 is fixedly connected to the right side of the housing 2. The handle 15 extends to the upper right to accommodate the operator's pushing posture. The handle 15 allows the operator to manually control the movement of the pressure roller device. At the same time, in order to improve the convenience of operation, a groove is opened on the outer right side of the handle 15. A switch button 16 is embedded in the groove and fixedly connected. The switch button 16 is electrically connected to the power box 2 11 and the control terminal 2 12, so that the operator can directly control the start and stop of the device while holding the handle 15.

[0036] As a further preferred embodiment, in order to realize the intelligent collaborative operation of the filling device and the compaction device in the combined mode, the second control terminal 12 and the first control terminal 8 establish a wireless communication connection through the built-in wireless communication module. The second control terminal 12 is configured to receive the control signals transmitted by the first control terminal 8, thereby adjusting the output state of the second power box 11, realizing the linkage operation of the pressure roller device and the compaction device, and ensuring that the compaction operation is carried out synchronously after the filling operation.

[0037] Working principle: In the combined mode, the boss 17 of the shell 2 is embedded into the limiting groove 18 of the bracket 1 and fixed by the connector, so that the filling device and the compaction device are combined into a whole. At the same time, the control terminal 1 8 and the control terminal 2 12 establish a wireless communication connection to achieve linkage. During operation, the repair material is added to the storage bin 5 through the feed port 6. The power box 1 7 is started, and the drive wheel 4 drives the entire device to move along the gap of the track. The storage bin 5 fills the gap with material through the discharge port 19. The push plate 10 following behind is in contact with the ground under the action of the telescopic rod 9. It cuts in with its arc front end and scrapes the material with its straight rear end. At the same time, the compaction device behind is started under the linkage signal. The power box 2 11 drives the pressure roller column 13 to rotate and immediately compacts the material that has just been scraped, realizing the integrated continuous operation of filling, scraping and compaction. In the separate mode, the filling device and the compaction device can work independently. The filling device can complete large-area filling and leveling operations by relying solely on the power box 7, wheels 4, discharge port 19, and push plate 10. The compaction device can be manually guided by the operator holding the handle 15 and starting the power box 11 through the switch button 16 to perform flexible compaction operations on specific areas, corners, or scattered repair points. When not in operation, the support seat 14 provides parking support for the compaction device. Through this combination and separation design, this utility model solves the problems of low efficiency caused by the single function and separation of processes in the existing repair equipment, or the poor flexibility of integrated equipment.
