Description

Technical Field

[0002] A runway refers to a road used for running, speed skating, and racing in a sports field. It also refers to a long strip of land at an airport for aircraft to take off or land. A runway can be paved with asphalt or concrete, or flattened grass, mud, or gravel. The flatness of the runway surface determines the overall quality of the runway. Therefore, after the runway is constructed, a flatness detection device is usually required to measure the flatness of the runway.

[0003] The utility model with the existing authorization announcement number CN218973463U discloses a flatness detection device for a plastic track, including a main body, a detection structure and a data recorder. The main body includes a frame and a slide rail, the slide rail is connected to the bottom position of the frame, the data recorder is arranged on the detection structure, and the detection structure has a slide groove adapted to the slide rail.

[0004] With the above technical solution, a counterweight is provided in the rotating structure, so that the probe always points to the road surface along the direction of gravity, and accurate flatness data can be measured. However, with the above technical solution, when the runway surface flatness detection device is in use, the measurement area is small, and the flatness of only a straight line of the runway can be measured at a time, and a wider runway surface cannot be quickly detected, which affects the detection efficiency of the runway surface flatness. In addition, the flatness of the runway surface can only be measured, and the inclination of the runway itself cannot be measured, which affects the measurement accuracy of the overall flatness of the runway surface.

[0005] To this end, we propose a runway pavement flatness detection device to solve the above problems. Utility Model Content

[0016] In summary, the technical effects and advantages of this application are:

[0017] 1. By providing a support plate and a connecting frame, when the rotating wheels contact the runway surface and rotate to move, the eight rotating wheels can cover a larger area of ​​the runway surface. Then, when a bulge or depression appears on the runway surface, the rotating wheels and the guide rods will push the first push plate to push the first pressure sensor upward and force the first spring to contract, and the first pressure sensor receives a larger pressure data. Alternatively, the rotating wheels and the guide rods move downward, and the first spring pushes the first pressure sensor downward, and the pressure data received by the first pressure sensor becomes smaller.

By setting the movable frame itself to cooperate with the adjusting frame and the connecting frame, and the rolling of the fixed frame and the roller frame, first use the level to adjust the telescopic plate and the adjusting frame to a horizontal position, and let the roller frame roll outside the runway surface. Then, when the runway surface is tilted, the connecting frame will rise and fall due to the movement of the movable frame. At this time, the second spring cooperates with the second push plate to make the second pressure sensor receive different pressure signals, so that the inclination of the runway surface itself can be detected, so that the runway surface flatness detection device can detect the inclination of the runway surface and increase the overall flatness detection accuracy of the runway surface.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4 , a runway pavement flatness detection device comprises an adjusting frame 1, a movable frame 2 is fixedly connected to the bottom surface of the adjusting frame 1, a connecting frame 3 is fixedly connected to the bottom surface of the movable frame 2, a supporting plate 4 is fixedly connected to the bottom surface of the connecting frame 3, eight guide rods 5 are slidably connected inside the supporting plate 4, the bottom end of each guide rod 5 is fixedly connected to a rotating wheel 6, the top of each guide rod 5 is fixedly connected to a first push plate 7, eight first springs 9 are fixedly connected to the bottom surface of the connecting frame 3, a first pressure sensor 8 is fixedly connected to the bottom surface of each first spring 9, a plurality of limit rods 17 are fixedly connected to the upper surface of each first push plate 7, the top end of each limit rod 17 penetrates the first pressure sensor 8 and extends to the top of the first pressure sensor 8, the limit rod 17 can limit the distance between the first push plate 7 and the first pressure sensor 8 without affecting the smooth up and down movement of the first push plate 7, so as to ensure that the first push plate 7 allows the first pressure sensor 8 to smoothly receive the pressure signal.

[0026] The sensing end of each first pressure sensor 8 is in contact with the upper surface of the first push plate 7, and a telescopic rod 18 is provided inside each first spring 9. The telescopic end of each telescopic rod 18 is fixedly connected to the upper surface of the first pressure sensor 8, and the top end of each telescopic rod 18 is fixedly connected to the inner top wall of the connecting frame 3. The telescopic rod 18 can assist the first spring 9 in telescoping, so that the first spring 9 is not prone to excessive displacement, thereby improving the reliability of the use of the first spring 9.

[0027] Two second push plates 10 are fixedly connected to the upper surface of the connecting frame 3, and two second springs 11 are fixedly connected to the bottom surface of the adjusting frame 1. The bottom end of each second spring 11 is fixedly connected to a second pressure sensor 12. An oscilloscope 19 and two batteries 20 are fixedly connected to the upper surface of the adjusting frame 1. Each first pressure sensor 8, each second pressure sensor 12 and the oscilloscope 19 are electrically connected to the battery 20 through a wire, and each first pressure sensor 8 and each second pressure sensor 12 are electrically connected to the oscilloscope 19 through a wire. The oscilloscope 19 can receive the pressure data electrical signals of the first pressure sensor 8 and the second pressure sensor 12 and display them in a wave form, which is convenient for the staff to distinguish and record the flatness of the runway surface. The battery 20 can provide the required electrical energy for the electrical equipment of the device.

[0028] The sensing end of each second pressure sensor 12 is in contact with the upper surface of the second push plate 10. Two telescopic plates 13 are slidably connected inside the adjusting frame 1. The upper surface of each telescopic plate 13 is provided with positioning holes 21 arranged at equal distances. Two positioning pins 22 are clamped on the inner wall of the adjusting frame 1. The bottom end of each positioning pin 22 passes through the adjusting frame 1 and one of the positioning holes 21 in sequence and extends to the bottom of the adjusting frame 1. The positioning holes 21 cooperate with the positioning pins 22 to locate the position of the telescopic plate 13 after telescopic adjustment, so that the telescopic plate 13 can be firmly fixed in position after being adjusted according to the runway width, thereby ensuring the reliability of the use of the telescopic plate 13.

[0029] Two limit rings 23 are fixedly connected to the outer surface of each telescopic plate 13, and each limit ring 23 is slidably connected to the inside of the adjustment frame 1. The limit ring 23 can increase the telescopic stability of the telescopic plate 13 without affecting the smooth telescopic movement of the telescopic plate 13, thereby further improving the use effect of the telescopic plate 13.

[0030] A fixing frame 14 is provided on the side where the two telescopic plates 13 are away from each other, and a roller frame 15 is fixedly connected to the bottom surface of each fixing frame 14, and a sliding block 24 is fixedly connected to the side where the two telescopic plates 13 are away from each other, and each sliding block 24 is slidably connected to the inside of the fixing frame 14, and a screw 25 is rotatably connected to the inside of each fixing frame 14, and each screw 25 is threadedly connected to the sliding block 24. By utilizing the rotational connection relationship between the screw 25 and the fixing frame 14 and the threaded connection relationship with the screw 25, the position of the sliding block 24 in the fixing frame 14 can be adjusted by rotation, and then the height difference between the telescopic plate 13 and the adjustment frame 1 and the runway pavement can be adjusted, thereby increasing the adaptability of the device.

[0031] The left side of each fixing frame 14 is fixedly connected with a level 16, the top of each screw rod 25 is fixedly connected with a knob 26, the bottom of each knob 26 is sleeved with a bearing 27, and each bearing 27 is fixedly embedded in the inside of the fixing frame 14. The knob 26 can facilitate the staff to manually rotate the screw rod 25, increasing the convenience of manual operation of the screw rod 25. The bearing 27 can limit the position of the screw rod 25 inside the fixing frame 14 without affecting the smooth rotation of the screw rod 25.

[0032] The working principle of the utility model is as follows: when in use, the device is first moved to the runway surface where the flatness needs to be detected, and the telescopic plate 13 is telescopically adjusted inside the adjustment frame 1 to cooperate with the positioning pin 22 and the positioning hole 21 to adapt to different fast runway surfaces, and then the knob 26 is used to rotate the screw rod 25 to cooperate with the sliding block 24 to slide inside the fixed frame 14 to adapt to the height difference between the adjustment frame 1 and the runway surface, so that the rotating wheel 6 contacts the runway surface and provides a certain thrust to the first pressure sensor 8. At this time, through the support plate 4 and the connecting frame 3, when the rotating wheel 6 contacts the runway surface and rotates, the eight rotating wheels 6 can cover a larger area of ​​the runway surface, and then when a convexity or concave appears on a runway surface, the rotating wheel 6 and the guide rod 5 will push the first push plate 7 to push the first pressure sensor 8 upward and force the first spring 9 to contract, and the first pressure sensor 8 receives a larger pressure data, or the rotating wheel 6 and the guide rod 5 move downward and the first spring 9 pushes the first pressure sensor 8 to move downward. The device 8 moves downward, and the pressure data received by the first pressure sensor 8 becomes smaller. At this time, the flatness data of the runway surface can be measured, so that the runway surface flatness detection device can quickly detect the flatness of a wider runway surface, thereby ensuring the flatness detection efficiency of the runway surface. In addition, through the activity of the movable frame 2 itself, the adjusting frame 1 and the connecting frame 3, as well as the rolling of the fixed frame 14 and the roller frame 15, the telescopic plate 13 and the adjusting frame 1 are first adjusted to a horizontal position using the level 16, and the roller frame 15 is allowed to roll outside the runway surface. Then, when the runway surface is tilted, the connecting frame 3 will be tilted up and down due to the activity of the movable frame 2. At this time, the second spring 11 cooperates with the second push plate 10 to make the second pressure sensor 12 receive different pressure signals, so that the inclination of the runway surface itself can be detected, so that the runway surface flatness detection device can detect the inclination of the runway surface, effectively increasing the overall flatness detection accuracy of the runway surface.
