Description

Technical Field

[0001] The utility model belongs to the technical field of airport runway pavement construction, and particularly relates to an airport runway pavement construction device. Background Art

[0002] An airport runway is a runway for aircraft to run on. Different from traditional roads, it has relatively high requirements for the flatness of the runway. For airport runways in high-temperature and humid areas, which are constantly exposed to high temperatures and heavy rainstorms all year round, the requirements for the runway are even higher. Specifically, in high-temperature and humid areas, the runway expands and contracts violently under high-temperature environments, and coupled with the constant heavy rain washing the runway, it is extremely easy to deform.

[0003] Therefore, when constructing this type of runway, in order to keep the runway pavement still maintain a very high flatness after a long time of use, during the process of pouring and leveling the concrete layer in the later stage of runway construction, the leveling process of the runway has relatively strict requirements.

[0004] Specifically, after pouring the concrete, first, large-scale leveling machinery conducts preliminary rough rolling and leveling on the runway, and then construction workers use rollers with different weights to finely level the runway in a rolling manner.

[0005] The specific method is to first use a relatively heavy long roller to level and compact the leveling surface while leveling. Subsequently, use a light long roller to level it again. The runway that is not fully leveled is rolled and leveled again, such as leveling uneven structures such as wrinkles on the concrete runway.

[0006] In the actual construction process, due to the relatively long length of the runway, after repeatedly leveling the relatively heavy long roller several times along the length direction of the runway, replace it with a light long roller for final leveling. Obviously, the disadvantage of this method is that the leveling efficiency is too low. It requires operators to drive the roller body to continuously roll back and forth on the runway, and uneven positions need to be repeatedly rolled. The construction efficiency is extremely low. Moreover, during the final fine leveling process, since operators cannot effectively control the leveling force, there is often over-rolling and leveling, resulting in insufficient horizontality of the pavement after leveling.

[0007] Based on the above background, the purpose of the utility model is to provide an airport runway pavement construction device.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An airport runway pavement construction device includes tracks arranged at intervals on both sides;

[0010] A runway panel rolling and leveling mechanism is arranged to roll between the tracks. The runway panel rolling and leveling mechanism includes a moving center frame, and roller mechanisms rolling on the tracks are respectively assembled and connected to both ends of the moving center frame;

[0016] Preferably, the locking structures are respectively the first adjusting screw rod and the second adjusting screw rod arranged on both sides of the swing frame;

[0017] Rectangular adjusting openings corresponding to the first adjusting screw rod and the second adjusting screw rod are formed on both sides of the top of the swing frame. During the swinging process of the swing frame, the first adjusting screw rod and the second adjusting screw rod swing relative to the rectangular adjusting openings.

[0038] Embodiment 1

[0039] As Figures 1 - 5 shown, a construction device for airport runway pavement includes tracks 1 arranged at intervals on the front and rear sides. The tracks 1 are made of lightweight alloy materials, such as aluminum alloy materials, which are convenient to carry. During the construction process, the tracks 1 are installed on the tops of the templates for formwork support on both sides of the runway in the existing manner. The method is to use a fastening method such as bolts (for example, a plurality of installation holes are provided on the track 1, and bolts are welded on the top of the template, and the track 1 is fastened through this method).

[0040] In order to achieve automatic fine leveling, a runway panel rolling and leveling mechanism is arranged to roll between the above-mentioned tracks 1.

[0041] The specific structure of the runway panel rolling and leveling mechanism is as follows:

[0042] The runway panel rolling and leveling mechanism includes a moving center frame 2, and roller mechanisms that roll on the track 1 are respectively assembled and connected to both ends of the moving center frame 2; the moving center frame 2 is enabled to automatically roll between the tracks 1 through the roller mechanisms.

[0043] Meanwhile, a leveling roller assembly is assembled and connected to the top of the moving center frame 2. The leveling roller assembly includes a vertical adjustment frame 4 arranged between the front and rear sides. Swing frames 5 are respectively rotatably connected to the vertical adjustment frame 4. A first leveling roller 61 with different weight and a second leveling roller 62 are respectively assembled and connected between both ends of the swing frame 5.

[0044] Specifically, the weight of the first leveling roller 61 is greater than that of the second leveling roller 62, and the first leveling roller 61 and the second leveling roller 62 are distributed in a left - right manner.

[0045] Specifically, during the construction process, first, the first leveling roller 61 is adjusted downward to contact the concrete pavement, and the initial rolling and leveling are achieved by repeatedly moving back and forth between the tracks 1 using the heavy roller. Then, the second leveling roller 62 is lowered. At this time, the first leveling roller 61 is raised, and fine leveling is performed again in the same way.

[0046] In this way, the concrete pavement is leveled in a rough and fine manner with a very high leveling efficiency.

[0047] Specifically, the swing frame 5 includes a horizontally arranged U - shaped part, and vertical parts that droop are integrally formed at the left and right ends of the U - shaped part. The first leveling roller 61 and the second leveling roller 62 are rotatably connected between the vertical parts.

[0048] Meanwhile, a rectangular opening is formed on the vertical adjustment frame 4. Rotating seats are respectively fixedly connected to the central parts of the front and rear side walls of the U - shaped part. A rotating shaft is fixedly connected to the rotating seat, and the rotating shaft is rotatably connected in the rectangular opening.

[0049] After raising or lowering the first leveling roller 61 or the second leveling roller 62, the swing frame 5 is positioned to facilitate the positioning of the first leveling roller 61 or the second leveling roller 62.

[0050] Specifically, the swing frames 5 on the front and rear sides are respectively positioned through a locking structure. The specific structure of the locking structure is:

[0051] The locking structure respectively includes a first adjusting screw 73 and a second adjusting screw 71 arranged on both sides of the swing frame 5; rectangular adjusting openings corresponding to the first adjusting screw 73 and the second adjusting screw 71 are respectively formed on the left and right sides of the top of the swing frame 5. During the swinging process of the swing frame 5, the first adjusting screw 73 and the second adjusting screw 71 swing relative to the rectangular adjusting openings.

[0052] Because the rectangular adjustment opening has a certain width, and the first adjustment screw 73 and the second adjustment screw 71 have a certain height, when the swing frame 5 is pressed toward the left side, the right side is raised or the right side is pressed down. During the process of raising the left side, the first adjustment screw 73 and the second adjustment screw 71 on both sides swing relative to the rectangular adjustment opening.

[0053] After swinging, in order to achieve positioning, the first adjusting screw 73 is threadedly connected with a lifting nut 731, and the lifting nut 731 presses the bottom of the swing frame 5; the second adjusting screw 71 is threadedly connected with a pressing nut 72, and the pressing nut 72 presses down the top of the swing frame 5.

[0054] The lifting nuts 731 and the pressing nuts 72 on both sides are respectively screwed toward the direction of the swing frame 5 until they are supported on both sides of the swing frame 5, so as to maintain the positioning under the resistance of the lifting nuts 731 and the pressing nuts 72.

[0055] For example, during the left side lifting process, the operator presses down the swing frame 5 on the right side, and after pressing down, the lifting nut 731 and the pressing nut 72 are pressed against the two sides of the swing frame 5. During the right side lifting process, the pressing nut 72 is adjusted down in advance, and after the lifting nut 731 is adjusted up, the swing frame 5 is swung, and the lifting nut 731 and the pressing nut 72 are randomly pressed against the two sides of the swing frame 5.

[0056] This method allows the first smoothing roller 61 or the second smoothing roller 62 to be pressed down in a very flexible manner to perform smoothing operations, while the other roller is raised without interfering with the operation. Secondly, the force of contact with the road surface can be adjusted by the height of the first smoothing roller 61 or the second smoothing roller 62, thereby adjusting the smoothing force. Finally, the first smoothing roller 61 or the second smoothing roller 62 can be positioned in a fixed position during the smoothing operation, thereby achieving high smoothness.

[0057] Example 2

[0058] like Figures 1 - 5 As shown, based on the structure of the first embodiment, in order to achieve high-efficiency smoothing operation during the smoothing process, the roller mechanism 3 includes a roller frame 31, on which a roller 33 is assembled and connected, and a motor 34 (a forward and reverse motor 34) is fixedly assembled and connected on the top of the roller frame 31 for driving the roller 33 to roll. Specifically, according to the method disclosed in the prior art, the output shaft of the motor 34 is mounted on the axle of the roller 33 (the axle of the roller 33 is rotatably connected to the roller frame 31), and the motor body is mounted on the top of the roller frame 31.

[0059] The roller frame 31 is installed at the end of the mobile center frame 2 through a spacing adjustment structure. In this way, it is possible to adjust the width of the road surface to meet the needs of various road surface processing.

[0060] Specifically, a number of sliding adjustment rods 32 are fixedly connected to the roller frame 31. A number of chutes for slidably connecting the sliding adjustment rods 32 are provided on the roller frame 31. A number of locking bolts 321 for locking the sliding adjustment rods 32 are threadedly connected to the top of the moving center frame 2 near the edge. After the locking bolts 321 penetrate through the moving center frame 2, they are pressed against the sliding adjustment rods 32. Specifically, after loosening the locking bolts 321, the distance between the front and rear roller frames 31 is adjusted by sliding and stretching the sliding adjustment rods 32.

[0061] The longitudinal cross-sectional shape of the above-mentioned track 1 is H-shaped, and the rollers roll in the track groove of the track 1. Specifically, the inner side wall of the H-shaped track 1 has a rectangular track groove, and the rollers 33 roll in the rectangular track groove. Under the operation of the motor 34, the automatically rotating rollers 33 achieve self-movement by relying on the frictional force with the rectangular track groove. In this way, the roller mechanism moves back and forth between the tracks 1 to repeatedly level the runway surface without manual operation. This leveling method is very efficient.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
