Description

Technical Field

[0001] This utility model relates to the field of pavement strength testing technology, specifically an airport runway pavement strength testing system. Background Technology

[0002] In airport construction and operation, runway strength is one of the most important parameters. It is used to assess the runway's load-bearing capacity and durability to ensure safe and efficient flight operations, ensure that the airport runway meets the standards for use, and ensure the safety of aircraft. Surface strength testing devices are needed to test the runway after construction to ensure its safety and reliability.

[0003] The prior art discloses an airport runway pavement strength testing device with application number CN202420563397.4. This application uses a bidirectional threaded rod. When testing the pavement, a second servo motor can be activated to drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it can drive the two moving blocks on both sides to move. When the two moving blocks move inward at the same time, the moving blocks can push the mounting box to move through the connecting rod. When the mounting box moves down, it can put the test block against the ground to apply pressure. At the same time, the test block squeezes the pressure plate. The pressure plate can be used with a pressure gauge to view the test data so as to check the strength of the runway pavement.

[0004] However, when the device is used to inspect the road surface, it cannot remove obstacles and garbage on the road surface. When garbage remains at the inspection location, it will reduce the accuracy of the inspection data of the roadbed and road surface. At the same time, the inspection blocks of the device are inconvenient to replace. Due to the long-term use of the same inspection block, the inspection block will be damaged. Therefore, it is necessary to be able to replace the inspection block at any time. If it cannot be replaced, it will also seriously affect the accuracy of the inspection structure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an airport runway surface strength testing system to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an airport runway pavement strength testing system, comprising a base, a connecting frame at the bottom of the base, a rotating roller connected to the inner side of the connecting frame via a connecting shaft, a transmission belt on the outer surface of the rotating roller, and bristles on the outer surface of the transmission belt, a driven rotating wheel fixed to one end of the connecting shaft, a motor mounted on one side of the top of the base, an output end of the motor connected to a driving rotating wheel, the outer surfaces of the driving and driven rotating wheels being connected by a transmission belt, a mounting frame mounted in the middle of the top of the base, and a hydraulic rod mounted inside the mounting frame at the bottom, the output end of the hydraulic rod connected to a mounting box, and the interior of the mounting box... A pressure sensor is installed at the top, and a movable plate is movably connected to the lower part of the mounting box. Insertion boxes are located on both sides of the bottom of the movable plate. A fixing plate is fixed inside each insertion box. A movable plate is connected to one side of the fixing plate via a spring. A second toothed rod is fixed to one side of the movable plate, and a limit block is fixed to the other side of the movable plate. A gear is installed on the other side of the fixing plate. A first toothed rod passes through one side of the insertion box, and a force-bearing plate is fixed to one end of the first toothed rod. A rotating shaft is installed at the bottom of the movable plate, and an eccentric wheel is fixed to the outer surface of the rotating shaft. An insertion port passes through the bottom of the insertion box, and a test block is connected inside the insertion port via an insertion rod. A limit groove is formed on one side of the insertion rod.

[0007] Furthermore, a fixing frame is fixed on both sides of the bottom of the base, a movable wheel is installed at the bottom of the fixing frame, a rotating shaft is installed on the inner side of the fixing frame, a brake plate is fixed on the outer surface of the rotating shaft, a bidirectional worm gear is installed on the outer surface of the fixing frame, and a worm wheel is fixed at the end of the rotating shaft.

[0008] By adopting the above technical solution, the moving wheel enables the device to move to the detection position. Then, the operator rotates the bidirectional worm gear, which causes the worm wheel to rotate. After the worm wheel rotates, the designated plate can be flipped, so that the designated plate is firmly attached to the ground. This can prevent the moving wheel from shifting during the detection process and affecting the stability of the device.

[0009] Furthermore, the bidirectional worm gear meshes with a worm wheel, and a crank is fixed to one end of the bidirectional worm gear.

[0010] By adopting the above technical solution, the rotation of the bidirectional worm gear can drive the rotation of the worm wheel, and the crank handle makes the rotation of the bidirectional worm gear more convenient.

[0011] Furthermore, the brake plate is provided in two sets, and the bottom of the two sets of brake plates is serrated.

[0012] By adopting the above technical solution, the brake plate can adhere to the ground to improve the stability of the device, and the serrated shape can further increase the friction between the brake plate and the road surface.

[0013] Furthermore, a knob is fixed to the bottom end of the rotating shaft.

[0014] By adopting the above technical solution, staff can more easily rotate the shaft using a knob.

[0015] Furthermore, the outer surface of the mounting bracket is provided with a control panel, and a storage battery is installed on one side of the top of the base. The control panel is electrically connected to the pressure sensor, hydraulic rod, storage battery and motor respectively.

[0016] By adopting the above technical solution, the battery can provide power to the pressure sensor, hydraulic rod and motor. The pressure sensor can transmit the detection data to the control panel, which makes it easy for the staff to check the strength of the road surface. The control panel can also control the motor and hydraulic rod.

[0017] Furthermore, the top of the insertion rod and the bottom of the limiting block are both sloped, and the limiting block is adapted to the limiting groove.

[0018] By adopting the above technical solution, the ramp-shaped design can guide the force. When the plug block is inserted into the socket and presses against the limiting block, the limiting block will overcome the elasticity of the spring and move laterally. When the limiting groove corresponds to the position of the limiting block, the spring can push the limiting block into the limiting groove, thereby achieving the purpose of installing and fixing the test block.

[0019] Furthermore, both the first and second racks mesh with gears.

[0020] By adopting the above technical solution, the first rack can rotate when it moves, and the rotation of the gear can drive the second rack to move.

[0021] Furthermore, a handle is fixed to the other side of the top of the base, and a rubber sleeve is fitted onto the outer surface of the handle.

[0022] By adopting the above technical solution, the handle makes it easier for staff to push the device to move, and the rubber sleeve can increase the friction and comfort between the staff's palm and the handle.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model comprises a motor, a driving wheel, a driven wheel, a transmission belt, a connecting shaft, a rotating roller, a transmission belt, and brush bristles. When the entire detection device is moved to the detection position, the operator starts the motor. The rotation of the motor causes the driving wheel to rotate, which in turn causes the transmission belt to drive the driven wheel to rotate. This, in turn, causes the connecting shaft to drive the rotating roller to rotate, which in turn causes the transmission belt to rotate. The rotation of the rotating roller causes the transmission belt to rotate, which allows the brush bristles to sweep the garbage on the road to one side. This avoids garbage remaining at the detection position and ensures that the detection position is free from garbage interference, thereby effectively improving the accuracy of the detection data.

[0025] 2. This utility model comprises a first toothed rod, a second toothed rod, a gear, a plug rod, a plug box, a spring, a limiting block, a limiting groove, an eccentric wheel, a rotating shaft, and a force plate. When the test block is damaged, the operator rotates the rotating shaft, which causes the eccentric wheel to rotate. The rotation of the eccentric wheel can compress the force plate, thereby causing the first toothed rod to move. The movement of the first toothed rod will drive the gear to rotate, which in turn causes the second toothed rod to pull the movable plate to overcome the elastic movement of the spring, thereby causing the limiting block to disengage from the limiting groove. This allows the plug rod to be pulled out of the plug box, thus achieving the purpose of disassembling the test block. This makes the replacement of the impact block simple and convenient, thereby greatly improving the practicality and user experience of the device. By replacing the damaged test block, the accuracy of the test results can be further guaranteed.

[0026] 3. This utility model is equipped with a bidirectional worm gear, a worm wheel, a rotating shaft, and a brake plate. When the device is moved to the detection position, in order to avoid the moving wheel affecting the stability of the device, the operator rotates the bidirectional worm gear. The rotation of the bidirectional worm gear causes the worm wheel to rotate, which in turn causes the designated plate to flip over, thereby making the designated plate tightly adhere to the ground. This can prevent the moving wheel from shifting during the detection process and affecting the stability of the device. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: An airport runway pavement strength testing system, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a base 1, with a connecting frame 10 at its bottom. A rotating roller 17 is connected to the inner side of the connecting frame 10 via a connecting shaft 16. A transmission belt 18 is provided on the outer surface of the rotating roller 17, and bristles 22 are provided on the outer surface of the transmission belt 18. A driven rotating wheel 20 is fixed to one end of the connecting shaft 16. A motor 8 is mounted on one side of the top of the base 1, and a handle 5 is fixed to the other side of the top of the base 1. A rubber sleeve is fitted onto the outer surface of the handle 5, facilitating movement by the operator. The rubber sleeve increases friction and comfort between the operator's hand and the handle 5. An active rotating wheel 19 is connected to the output end of the motor 8. The outer surfaces of the active rotating wheel 19 and the driven rotating wheel 20 are connected by a transmission belt 21. A mounting frame 2 is mounted in the middle of the top of the base 1, and a hydraulic rod 3 is mounted inside the lower part of the mounting frame 2. A mounting box 4 is connected to the output end of the hydraulic rod 3, and a pressure sensor is mounted inside the upper part of the mounting box 4. The device 23 has a movable disk 24 movably connected to the lower part of the mounting box 4. The bottom of the movable disk 24 is provided with plug boxes 25 on both sides. The plug box 25 has a fixed plate 28 fixed inside. One side of the fixed plate 28 is connected to a movable plate 30 through a spring 37. One side of the movable plate 30 is fixed with a second toothed rod 38. The other side of the movable disk 24 is fixed with a limit block 39. The other side of the fixed plate 28 is equipped with a gear 36. One side of the plug box 25 has a first toothed rod 35 passing through it. One end of the first toothed rod 35 is fixed with a force plate 31. The bottom of the movable disk 24 is equipped with a rotating shaft 26. The outer surface of the rotating shaft 26 is fixed with an eccentric wheel 27. The bottom end of the rotating shaft 26 is fixed with a knob. The operator can make the rotating shaft 26 rotate more conveniently by turning the knob. The bottom of the plug box 25 has a plug 29 passing through it. The inside of the plug 29 is connected to a test block 33 through a plug rod 32. One side of the plug rod 32 has a limit groove 34.

[0036] See Figure 1 In the above embodiment, the outer surface of the mounting bracket 2 is provided with a control panel 6, and a storage battery 7 is installed on one side of the top of the base 1. The control panel 6 is electrically connected to the pressure sensor 23, the hydraulic rod 3, the storage battery 7 and the motor 8 respectively. The storage battery 7 can provide power to the pressure sensor 23, the hydraulic rod 3 and the motor 8. The pressure sensor 23 can transmit the detection data to the control panel 6, which makes it convenient for the staff to check the strength of the road surface. The control panel 6 can also control the motor 8 and the hydraulic rod 3.

[0037] See Figure 4 and Figure 5In the above embodiment, the top of the insertion rod and the bottom of the limiting block 39 are both sloped, and the limiting block 39 is adapted to the limiting groove 34. The sloped design can guide the force. When the insertion block is inserted into the insertion port 29 and presses against the limiting block 39, the limiting block 39 will overcome the elasticity of the spring 37 and move laterally. When the limiting groove 34 and the limiting block 39 are aligned, the spring 37 can push the limiting block 39 into the limiting groove 34, thereby achieving the purpose of installing and fixing the test block 33.

[0038] See Figures 4-5 In the above embodiments, both the first rack 35 and the second rack 38 mesh with the gear 36. When the first rack 35 moves, it can cause the gear 36 to rotate, and the rotation of the gear 36 can drive the second rack 38 to move.

[0039] Example 2: To enable the device to move and to avoid the moving wheels affecting the stability of the device during testing, Example 2 is an improvement on Example 1. (See attached document.) Figures 1-2 The base 1 has fixed frames 9 on both sides of its bottom. The bottom of the fixed frame 9 is equipped with a movable wheel 14. The inner side of the fixed frame 9 is equipped with a rotating shaft 12. The outer surface of the rotating shaft 12 is fixed with a brake plate 15. The outer surface of the fixed frame 9 is equipped with a bidirectional worm gear 11. The end of the rotating shaft 12 is fixed with a worm wheel 13. The movable wheel 14 allows the device to move to the detection position. Then, the operator rotates the bidirectional worm gear 11. The rotation of the bidirectional worm gear 11 causes the worm wheel 13 to rotate. After the worm wheel 13 rotates, it can flip the designated plate, so that the designated plate is closely attached to the ground. This can prevent the movable wheel 14 from shifting during the detection process and affecting the stability of the device.

[0040] See Figures 1-2 In the above embodiment, the bidirectional worm 11 meshes with the worm wheel 13, and a rocker arm is fixed to one end of the bidirectional worm 11. The rotation of the bidirectional worm 11 can drive the worm wheel 13 to rotate, and the rocker arm can make the rotation of the bidirectional worm 11 more convenient.

[0041] See Figures 1-2 In the above embodiment, the brake plate 15 is provided in two sets, and the bottom of the two sets of brake plates 15 is serrated. The brake plate 15 can fit on the ground to improve the stability of the device, and the serration can further increase the friction between the brake plate and the road surface.

[0042] The implementation principle of this utility model is as follows: When the entire detection device is moved to the detection position, the operator starts the motor 8. The rotation of the motor 8 causes the active rotating wheel 19 to rotate, which in turn causes the transmission belt 21 to drive the driven rotating wheel 20 to rotate, which in turn causes the connecting shaft 16 to drive the rotating roller 17 to rotate. The rotation of the rotating roller 17 causes the transmission belt 18 to rotate. The rotation of the transmission belt 18 allows the bristles 22 to sweep the garbage on the road to one side, thus preventing garbage from remaining at the detection position. After the device is moved to the detection position, in order to prevent the moving wheel 14 from affecting the stability of the device, the operator rotates the double-sided worm gear 11. The rotation of the double-sided worm gear 11 causes the worm wheel 13 to rotate. The rotation of the worm wheel 13 causes the positioning plate to flip, thus making the positioning plate tightly adhere to the ground, increasing the stability of the device. Then the operator starts the hydraulic system. Rod 3 and hydraulic rod 3 drive the mounting box 4 to move downwards, thereby causing the test block 33 to move downwards. The test block 33 contacts the road surface and applies pressure. At this time, the movable plate 24 applies pressure to the pressure sensor 23. The pressure sensor 23 transmits the detection data to the control panel 6 for the operator to view. When the test block 33 is damaged, the operator rotates the rotating shaft 26. The rotation of the rotating shaft 26 causes the eccentric wheel 27 to rotate. The rotation of the eccentric wheel 27 can squeeze the force plate 31, thereby causing the first toothed rod 35 to move. After the first toothed rod 35 moves, it will drive the gear 36 to rotate, thereby causing the second toothed rod 38 to pull the movable plate 30 to move against the elasticity of the spring 37, thereby causing the limit block 39 to disengage from the limit groove 34. In this way, the insertion rod 32 can be pulled out from the insertion box 25, thereby achieving the purpose of disassembling the test block 33.
