Description

Technical Field

[0001] This invention relates to the field of leveling equipment technology, specifically to a leveling device and method for surface concrete of airport runways. Background Technology

[0002] Airport pavement is a key infrastructure for the safe operation of civil aviation airports. Its performance requirements, such as flatness, density, wear resistance and frost resistance, are far higher than those of ordinary road pavement. At present, most airport pavements in China adopt the construction of a single-layer structure of semi-dry hard cement concrete with large thickness.

[0003] With rising labor costs, increasing prices of natural materials, and stricter requirements for low-carbon and environmental protection, the civil aviation sector has begun to promote a double-layer pavement structure system: the upper layer uses high-performance concrete to ensure surface smoothness, wear resistance, and frost resistance, while the lower layer introduces low-carbon and low-cost materials to maximize load-bearing capacity and reduce costs. The construction of the double-layer structure requires continuous paving operations to ensure the quality of interlayer bonding and structural integrity.

[0004] However, existing leveling equipment still has certain shortcomings. Some equipment only uses a single rolling or scraping method for leveling, which makes it difficult to meet the needs of both large-area leveling and local fine leveling. The leveling mechanism of some equipment has a limited adjustment range and cannot adapt to the construction of concrete layers of different thicknesses or edge areas. In addition, some equipment lacks stability during operation and is prone to wavy defects on the leveled surface due to vibration or uneven stress. In view of this, we propose a leveling equipment and method for the surface concrete of airport runways. Summary of the Invention

[0005] The purpose of this invention is to provide an equipment and method for leveling the surface concrete of airport runways, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An airport runway surface concrete leveling device includes vertical barriers and horizontal barriers, with two sets of the vertical and horizontal barriers. A surface concrete body is laid within the rectangular space enclosed by the two sets of vertical and horizontal barriers and the airport runway. Two sets of traveling trolleys are installed on the airport runway, with a horizontal beam fixedly installed between the tops of the two sets of traveling trolleys. The device also includes a swing assembly positioned between the two sets of vertical and horizontal barriers, moving with the horizontal beam. The swing assembly includes: A fixed frame is fixedly installed on one side of a horizontal beam. A hinge block is fixedly installed on the outer wall of the top of the fixed frame, and a hydraulic rod fixing end is hingedly installed on the hinge block. A hinged seat is fixedly installed on the bottom outer wall of the fixed frame. A rectangular frame is hingedly installed on the hinged seat. A round rod is fixedly installed on the end of the rectangular frame away from the hinged seat. The piston end of the hydraulic rod is hingedly installed on the end of the round rod away from the rectangular frame. A fixing block is fixedly installed at the center of one end of the rectangular frame away from the hinge seat. A fixing shaft is fixedly installed inside the fixing block, and a leveling roller is rotatably installed on the outside of the fixing shaft through a bearing component.

[0007] In a further embodiment, rollers are rotatably mounted on the horizontal beam via bearing components. The rollers roll and adhere to the upper surface of the vertical enclosure, making the swing assembly more stable.

[0008] In a further embodiment, two sets of the hinge block, hydraulic rod, hinge seat, round rod, and leveling roller are provided.

[0009] In a further embodiment, the two sets of hinge blocks, hydraulic rods, hinge seats, round rods, and leveling rollers are all symmetrically distributed with the vertical centerline of the horizontal beam as a mirror axis, thus achieving better leveling.

[0010] In a further embodiment, the fixed frame is provided with a movable component, the movable component including a top hydraulic cylinder, the top hydraulic cylinder being fixedly installed on the top of the fixed frame, a vertical plate being fixedly installed at the bottom of the piston end of the top hydraulic cylinder, a limit slide rail being fixedly installed on the inner wall of the fixed frame, and the side wall of the vertical plate being fixedly installed on the outer wall of the sliding member inside the limit slide rail.

[0011] In a further embodiment, two sets of top hydraulic cylinders and limiting slide rails are provided. Both sets of top hydraulic cylinders and limiting slide rails are symmetrically distributed with the vertical centerline of the fixed frame as a mirror axis, making the movement of the vertical plate more stable.

[0012] In a further embodiment, one end of a Y-shaped frame is fixedly connected to the bottom outer wall of the vertical plate, and a flat plate is fixedly installed on the other end of the Y-shaped frame. The side of the Y-shaped frame near the vertical plate is bent, making the flat plate more robust.

[0013] In a further embodiment, the bottom end of the leveling plate near the leveling roller is set as an arc-shaped slope to better conform to the guiding concrete.

[0014] In a further embodiment, an adjustment assembly is provided on the horizontal beam. The adjustment assembly includes a U-shaped frame, which is fixedly installed on the horizontal beam. An asynchronous motor is fixedly installed on the outer wall of the U-shaped frame, and a threaded rod is fixedly installed at the output end of the asynchronous motor. Both ends of the threaded rod are rotatably installed inside the U-shaped frame via bearing components. Threaded blocks are threadedly fitted onto the threaded rod. An auxiliary slide rail is fixedly installed on the inner wall of the U-shaped frame. One end of the threaded block is fixedly connected to the outer wall of the sliding component inside the auxiliary slide rail. The bottom of the threaded block is fixedly connected to the fixed end of an auxiliary hydraulic cylinder. A circular roller is fixedly installed at the bottom of the piston end of the auxiliary hydraulic cylinder. The side of the circular roller closer to the leveling roller has a circular cross-section, and the side of the circular roller away from the leveling roller has an arc-shaped cross-section for better and more complete leveling.

[0015] A leveling method for leveling the surface concrete of airport runways includes the following steps: S1. Start the traveling trolley so that the horizontal beam can move laterally; S2. Start the hydraulic rod, which works with the hinge block on the fixed frame to make the rectangular frame and the round rod swing around the connection point with the hinge seat as the swing center. At the same time, it drives the fixed block to move synchronously, so that the leveling roller moves synchronously and contacts the upper surface of the surface concrete. When the leveling roller moves laterally, it rotates on the fixed shaft to level the surface concrete. S3. After the swing assembly completes the large-area leveling, the top hydraulic cylinder is activated, and the limit slide rail is used to move the vertical plate up and down, thereby driving the Y-shaped frame to move up and down synchronously. As a result, the plate can move down to fit the upper surface of the surface concrete, and further leveling is completed under the drive of the traveling trolley. The curved slope can follow the guide concrete. S4. After the swing assembly and the moving assembly have completed the large-area leveling, the asynchronous motor on the U-shaped frame is started to make the threaded rod rotate. The threaded block moves laterally in conjunction with the auxiliary slide rail. When the auxiliary hydraulic cylinder is started to make the roller move up and down, the roller can move laterally to level the concrete at the edge of the horizontal enclosure. S5. At the same time, the circular and arc-shaped cross sections at both ends of the roller can further level the surface concrete.

[0016] Compared with the prior art, the present invention provides an equipment and method for leveling the surface concrete of airport runways, which has the following beneficial effects: 1. The airport runway surface concrete leveling equipment and method, in order to better level the surface concrete, is equipped with a swing component. When the traveling trolley is started, the horizontal beam can move laterally. When the hydraulic rod is started, in conjunction with the hinge block on the fixed frame, the rectangular frame and the round rod swing around the connection point with the hinge seat as the swing center, thereby driving the fixed block to move synchronously, so that the leveling roller moves synchronously and contacts the upper surface of the surface concrete. When the leveling roller moves laterally, it simultaneously rotates on the fixed shaft, thereby better leveling the surface concrete. The rollers make the swing component more stable.

[0017] 2. The airport runway surface concrete leveling equipment and method, in order to achieve better leveling results, is equipped with a moving component. After the swing component completes large-area leveling, the top hydraulic cylinder is activated, and in conjunction with the limit slide rail, the vertical plate moves up and down, thereby driving the Y-shaped frame to move up and down synchronously. As a result, the leveling plate can move downward to fit the upper surface of the surface concrete, and further leveling is completed under the drive of the traveling trolley. The curved slope can better conform to the guide concrete, resulting in a better leveling effect.

[0018] 3. The airport runway surface concrete leveling equipment and method, in order to further level the surface concrete, by setting up an adjustment component, after the swing component and the moving component have completed the leveling of a large area, the asynchronous motor on the U-shaped frame is started to make the threaded rod rotate, which, together with the auxiliary slide rail, makes the threaded block move laterally. When the auxiliary hydraulic cylinder is started, the roller moves up and down, so that the roller can move laterally to further level the concrete at the edge of the horizontal barrier. At the same time, the circular cross section and the arc cross section at both ends of the roller make the effect better, and then the surface concrete leveling can be further carried out.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0023] Please see Figures 1-8 The present invention provides a technical solution: An airport runway surface concrete leveling device includes vertical barriers 1 and horizontal barriers 2. Two sets of vertical barriers 1 and horizontal barriers 2 are provided. The surface concrete body is laid in the rectangular space enclosed by the two sets of vertical barriers 1 and horizontal barriers 2 and the airport runway. Two sets of traveling trolleys 3 are provided on the airport runway. A horizontal beam 4 is fixedly installed between the tops of the two sets of traveling trolleys 3.

[0024] In one embodiment of the present invention, a swing assembly 5 is further included, which is disposed between two sets of vertical barriers 1 and horizontal barriers 2 and moves with the horizontal beam 4. The swing assembly 5 includes a fixed frame 51, which is fixedly installed on one side of the horizontal beam 4. A hinge block 52 is fixedly installed on the outer wall of the top of the fixed frame 51. A hydraulic rod 53 is hingedly installed on the hinge block 52. A hinge seat 54 is fixedly installed on the outer wall of the bottom of the fixed frame 51. A rectangular frame 55 is hingedly installed on the hinge seat 54. A round rod 56 is fixedly installed at the end of the rectangular frame 55 away from the hinge seat 54. The piston end of the hydraulic rod 53 is hingedly installed at the end of the round rod 56 away from the rectangular frame 55. A fixing block 57 is fixedly installed at the center of one end away from the hinge seat 54. A fixing shaft 58 is fixedly installed inside the fixing block 57. A leveling roller 59 is rotatably installed on the outside of the fixing shaft 58 through bearing components. In addition, a roller 510 is rotatably installed on the horizontal beam 4 through bearing components. The roller 510 rolls and fits against the top of the vertical enclosure 1, making the swing component 5 more stable. Furthermore, there are two sets of hinge blocks 52, hydraulic rods 53, hinge seats 54, round rods 56, and leveling rollers 59. In addition, the two sets of hinge blocks 52, hydraulic rods 53, hinge seats 54, round rods 56, and leveling rollers 59 are symmetrically distributed with the vertical center line of the horizontal beam 4 as a mirror axis for better leveling.

[0025] In this embodiment, after the equipment is started, the traveling trolley 3 is started first, which drives the horizontal beam 4 to move laterally. When the hydraulic rod 53 in the swing assembly 5 is started, the fixed end of the hydraulic rod 53 is hinged to the hinge block 52 on the fixed frame 51. Under the driving action of the hydraulic rod 53, the rectangular frame 55 and the round rod 56 swing around the connection point with the hinge seat 54 as the swing center, thereby driving the fixed block 57 to move synchronously. The fixed shaft 58 inside the fixed block 57 moves synchronously, so that the leveling roller 59 sleeved on the outside of the fixed shaft 58 moves synchronously and contacts the upper surface of the surface concrete. During the process of the leveling roller 59 moving laterally with the horizontal beam 4, the leveling roller 59 rotates on the fixed shaft 58 through the bearing components. By using the combined motion of rotation and lateral movement, the surface concrete is initially leveled. At the same time, the roller 510 on the horizontal beam 4 rolls at the top of the vertical enclosure 1, providing stable support for the swing assembly 5 and ensuring that the leveling process is carried out smoothly.

[0026] In one embodiment of the present invention, a movable component 6 is provided on the fixed frame 51. The movable component 6 includes a top hydraulic cylinder 61, which is fixedly installed on the top of the fixed frame 51. A vertical plate 62 is fixedly installed at the bottom of the piston end of the top hydraulic cylinder 61. A limiting slide rail 63 is fixedly installed on the inner wall of the fixed frame 51. The side wall of the vertical plate 62 is fixedly installed on the outer wall of the sliding member inside the limiting slide rail 63. In addition, there are two sets of top hydraulic cylinders 61 and limiting slide rails 63. Both sets of top hydraulic cylinders 61 and limiting slide rails 63 are symmetrically distributed about the vertical centerline of the fixed frame 51 as a mirror axis, which makes the vertical plate 62 more stable when moving. In addition, one end of a Y-shaped frame 64 is fixedly connected to the outer wall of the bottom end of the vertical plate 62. A flat plate 65 is fixedly installed on the other end of the Y-shaped frame 64. The side of the Y-shaped frame 64 near the vertical plate 62 is bent, which makes the flat plate 65 more robust. In addition, the side of the bottom end of the flat plate 65 near the leveling roller 59 is set as an arc-shaped inclined surface 66 to better conform to the guide concrete.

[0027] In this embodiment, when the swing assembly 5 completes the initial leveling of the large area of ​​surface concrete, the top hydraulic cylinder 61 in the moving assembly 6 is activated. The piston end of the top hydraulic cylinder 61 drives the vertical plate 62 to move. The side wall of the vertical plate 62 is connected to the sliding part inside the limiting slide rail 63. Under the guidance of the limiting slide rail 63, the vertical plate 62 achieves stable up and down movement, which in turn drives the Y-shaped frame 64 to move up and down synchronously. The leveling plate 65 connected to the other end of the Y-shaped frame 64 moves down and fits against the upper surface of the surface concrete. Under the continuous drive of the traveling trolley 3, the leveling plate 65 further levels the concrete surface. The arc-shaped inclined surface 66 at the bottom of the leveling plate 65 near the leveling roller 59 can better conform to and guide the concrete, avoiding damage to the initially leveled surface and further improving the leveling effect.

[0028] In one embodiment of the present invention, an adjustment component 7 is provided on the horizontal beam 4. The adjustment component 7 includes a U-shaped frame 71, which is fixedly installed on the horizontal beam 4. An asynchronous motor 72 is fixedly installed on the outer wall of the U-shaped frame 71. A threaded rod 73 is fixedly installed at the output end of the asynchronous motor 72. Both ends of the threaded rod 73 are rotatably installed inside the U-shaped frame 71 through bearing components. A threaded block 74 is threadedly engaged on the threaded rod 73. An auxiliary slide rail 75 is fixedly installed on the inner wall of the U-shaped frame 71. One end of the threaded block 74 is fixedly connected to the outer wall of the sliding component inside the auxiliary slide rail 75. The bottom of the threaded block 74 is fixedly connected to the fixed end of the auxiliary hydraulic cylinder 76. A circular roller 77 is fixedly installed at the bottom of the piston end of the auxiliary hydraulic cylinder 76. The side of the circular roller 77 near the leveling roller 59 is set with a circular cross section, and the side of the circular roller 77 away from the leveling roller 59 is set with an arc-shaped cross section for better and more complete leveling.

[0029] In this embodiment, after the swing assembly 5 and the moving assembly 6 have completed large-area leveling, the asynchronous motor 72 in the adjusting assembly 7 is activated. The asynchronous motor 72 is mounted on the U-shaped frame 71, and its output end drives the threaded rod 73 to rotate. The threaded block 74 on the threaded rod 73 moves under the action of the thread. At the same time, one end of the threaded block 74 is connected to the sliding part inside the auxiliary slide rail 75. Under the guidance of the auxiliary slide rail 75, stable lateral movement is achieved. The auxiliary hydraulic cylinder 76 connected to the bottom of the threaded block 74 moves laterally with the threaded block 74. Activating the auxiliary hydraulic cylinder 76 can drive the circular roller 77 to move up and down, so that the circular roller 77 contacts the concrete at the edge of the horizontal barrier 2. The circular roller 77 moves laterally with the threaded block 74 to further level the concrete at the edge. Since the circular roller 77 has a circular cross section and an arc cross section at both ends, it can better adapt to the terrain of the edge area and ensure the leveling effect of the concrete at the edge. Finally, the overall leveling operation of the surface concrete of the entire airport runway is completed.

[0030] Then, leveling is carried out through a variety of methods, taking into account the needs of large-area leveling and local fine leveling, better adapting to the construction of concrete layers or edge areas of different thicknesses. In addition, it has good stability during operation, avoiding wavy defects in the leveling surface caused by vibration or uneven stress.

[0031] A leveling method for leveling the surface concrete of airport runways includes the following steps: S1. Start the traveling trolley 3 so that the horizontal beam 4 can move laterally; S2. Start the hydraulic rod 53, which works with the hinge block 52 on the fixed frame 51 to make the rectangular frame 55 and the round rod 56 swing around the connection point with the hinge seat 54 as the swing center. At the same time, it drives the fixed block 57 to move synchronously, so that the leveling roller 59 moves synchronously and contacts the upper surface of the surface concrete. When the leveling roller 59 moves laterally, it rotates on the fixed shaft 58 to level the surface concrete. S3. After the swing assembly 5 completes the large-area leveling, the top hydraulic cylinder 61 is activated, and the limit slide rail 63 is used to make the vertical plate 62 move up and down, thereby driving the Y-shaped frame 64 to move up and down synchronously. As a result, the leveling plate 65 can move down to fit the upper surface of the surface concrete. Under the drive of the traveling trolley 3, further leveling is completed, and the arc-shaped inclined surface 66 can follow the guide concrete. S4. After the swing assembly 5 and the moving assembly 6 have completed the large-area leveling, the asynchronous motor 72 on the U-shaped frame 71 is started to make the threaded rod 73 rotate. The threaded block 74 moves laterally in conjunction with the auxiliary slide rail 75. When the auxiliary hydraulic cylinder 76 is started to make the roller 77 move up and down, the roller 77 can move laterally to level the concrete at the edge of the horizontal enclosure 2. S5. At the same time, the circular and arc-shaped cross sections at both ends of the roller 77 can further level the surface concrete.

[0032] It should be noted that an external power supply is required on site, the equipment is powered externally, and it travels by cable; a PLC control system is adopted, the equipment is equipped with a touch screen to adjust parameters, and a wireless remote control is provided for simple operation. All electrical components mentioned in this application are electrically connected to the PLC control system, and the PLC control system is a conventional and known device that can control the traveling trolley 3, hydraulic rod 53, top hydraulic cylinder 61, asynchronous motor 72, and auxiliary hydraulic cylinder 76.
