Description

Technical Field

[0001] This application relates to the technical field of highway smoothness testing devices, and in particular to a highway smoothness testing device. Background Technology

[0002] Highway smoothness is an important indicator for measuring the smoothness of road surface, which directly affects driving comfort and safety. Good highway smoothness can reduce vehicle vibration and bumps, extend the service life of the road, and reduce vehicle maintenance costs. During highway construction, road smoothness testing is required to determine the quality of road construction.

[0003] The existing announcement number CN215906530U, entitled "A Highway Engineering Smoothness Testing Device," includes a housing with several first pulleys at the bottom and a push rod mounted on the housing. A second pulley is located at the bottom of the housing and is connected to a sliding member disposed within the housing cavity via a connecting rod. The sliding member can slide up and down within the housing, and a reset component is provided at the top to return the sliding member to its original position. The sliding member is fixed to a slope testing component disposed on the upper surface. The second pulley, in conjunction with the first pulleys, moves on the ground. When different slopes occur, the second pulley moves upward, causing the sliding member to move the bar upward, thus allowing the scale on the bar to be seen, facilitating the testing of ground smoothness.

[0004] Regarding the aforementioned technologies, the inventors discovered that the road surface smoothness detection device uses a roller to contact the road surface. When the road surface is uneven, the sliding part on the roller slides on the bar to indicate the unevenness. However, when moving to monitor the road surface, the sliding part on the bar is not obvious at small unevenness points, and the inspectors cannot detect it. The device also lacks a warning component during the inspection, making it impossible to promptly alert the inspectors to the inspection situation. Utility Model Content

[0005] In order to overcome the problems of existing mobile road surface monitoring where the sliding parts of small uneven areas do not slide obviously on the bar and cannot be detected by the inspectors, and the lack of warning components during the inspection makes it impossible to promptly alert the inspectors to the inspection situation, this application provides a road smoothness inspection device.

[0006] The highway smoothness testing equipment provided in this application adopts the following technical solution:

[0007] A road smoothness testing device includes a testing component and a warning component. The testing component includes a support frame, a guide tube frame vertically fixed on the top surface of the support frame, a sliding frame vertically fixed on the top surface of the guide tube frame, a guide post vertically slidably inserted into the guide tube frame, a sliding plate horizontally fixed on the top surface of the guide post, the sliding plate vertically slidably assembled in the support frame, a power base fixed on the top surface of the sliding plate, a stop post horizontally fixed on the front end surface of the power base, and a testing wheel vertically assembled at the bottom end of the guide post. The warning component includes a guide frame and an insulating plate. Two guide frames are symmetrically arranged, and the two guide frames are vertically fixed on both sides of the front end surface of the sliding frame. Multiple insulating plates are horizontally arranged vertically between the two guide frames, and a warning light is horizontally fixed in the middle of the multiple insulating plates. A power contact piece is fixed on the rear end surface of the warning light, and a terminal block is provided on the warning light.

[0008] By adopting the above technical solution, the spacing between multiple insulating plates between the two guide frames in the warning device is adjusted according to the error of road surface smoothness. The spacing between the multiple insulating plates classifies the unevenness of the road surface. When the support frame in the detection device moves on the detection road surface, the detection wheel presses against the detection road surface. When the road surface is uneven, the detection wheel drives the guide post to slide vertically on the guide cylinder post. When the abutment on the electrical base at the top of the guide post contacts and presses against the warning light electrical contact piece on the insulating plate, the conductive circuit of the warning light on the insulating plate is connected, so that the warning light on the insulating plate warns of the unevenness of the road surface. By using the warning lights set on multiple insulating plates, in conjunction with the abutment on the electrical base at the top of the guide post to emit light warnings, the unevenness of the road surface is warned during the detection of the road surface, which is conducive to the recording of the detection situation by the detection personnel.

[0009] Optionally, rollers are fixed on the bottom surface of the support frame, and a rotating seat is fixed on one end surface of the support frame. A rotating frame is rotatably connected to the rotating seat, and a screw seat is fixed through the end of the rotating frame.

[0010] By adopting the above technical solution, the support frame moves horizontally on the test surface under the support of the rollers, while the rotating frame connected to the rotating seat on one end face of the support frame is used to rotate and pull the test piece to move on the test surface.

[0011] Optionally, a screw rod is threaded through the screw barrel seat, and a pull frame is rotatably connected to the end of the screw rod.

[0012] By adopting the above technical solution, the screw can be rotated and moved threadedly in the screw barrel seat on the rotating frame according to the required pulling length, and the pulling length can be adjusted laterally. At the same time, the pulling frame is rotated and connected at the end of the screw, which facilitates the change of pulling posture.

[0013] Optionally, a battery is fixed to one side of the top surface of the support frame, and the output terminal of the battery is electrically connected to the terminal block and the power socket respectively through wires.

[0014] By adopting the above technical solution, the battery output terminal on the support frame is electrically connected to the terminal block and the power socket, which facilitates the power supply to the warning light.

[0015] Optionally, a stud is vertically fixed on the bottom surface of the guide post, and a screw shell is vertically fixed on the top surface of the detection wheel, with the screw shell and the stud being threadedly connected.

[0016] By adopting the above technical solution, the screw shell on the detection wheel is connected to the stud at the bottom of the guide post, which facilitates the later disassembly and replacement of detection wheels of different specifications and sizes.

[0017] Optionally, springs are vertically fixed to the upper surface of the skateboard, and the ends of the springs on the upper surface of the skateboard are fixed to the slide frame.

[0018] By adopting the above technical solution, the springs that are vertically fixed at both ends of the slide plate generate deformation force, which pushes the slide plate to move vertically on the slide frame. This makes it easier to restore the detection position of the detection wheel during subsequent inspection, thus adapting to the road surface inspection needs of different flatness levels during use.

[0019] Optionally, a screw hole is horizontally through the front end face of the guide frame, and multiple screw holes are opened in the vertical direction. Locking bolts are assembled in the screw holes of the guide frame with horizontal threads.

[0020] By adopting the above technical solution, locking bolts are assembled in the horizontal threads of the screw holes on the guide frame, which are used to adjust the warning levels of different warning lights according to the road surface smoothness specifications, so as to distinguish the level of road surface unevenness in a timely manner.

[0021] Optionally, guide blocks are fixed at both ends of the insulating plate, and the guide blocks are slidably assembled in the guide frame. Horizontal screw grooves are opened on the guide blocks, and the screw grooves are threadedly assembled with the locking bolts.

[0022] By adopting the above technical solution, when limiting the position of multiple insulating plates in the guide frame, the locking bolts are threaded through the guide frame and threaded into the screw grooves on the end guide blocks of the insulating plates, thus limiting and fixing the multiple insulating plates in the vertical position of the guide frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the spacing between multiple insulating plates between the two guide frames in the warning component is adjusted according to the error in road surface smoothness. The spacing between the multiple insulating plates classifies uneven road surfaces. During use, when the support frame in the detection component moves on the test road surface, the detection wheel presses against the test road surface. When the road surface is uneven, as the detection wheel passes through, the detection wheel drives the guide post to slide vertically on the guide cylinder post. When the abutment on the top of the guide post's electrical base contacts and presses against the warning light's electrical contact piece on the insulating plate, the conductive circuit of the warning light on the insulating plate is connected, thereby alerting the test personnel to road surface unevenness. By utilizing the warning lights set on multiple insulating plates, in conjunction with the abutment on the top of the guide post's electrical base to emit light warnings, it is possible to alert the test personnel to uneven road surfaces during road surface testing, facilitating the recording of test conditions.

The spacing between the multiple insulating plates 22 is used to classify the unevenness of the road surface. When the support frame 11 in the detection component 1 moves on the detection road surface, the detection wheel 17 presses against the detection road surface. When the road surface is uneven, the detection wheel 17 drives the guide post 15 to slide vertically on the guide cylinder post 12.

The warning lights 24 set on multiple insulating plates 22, together with the abutment 161 on the top electrical base 16 of the guide post 15, emit light warnings, thereby warning of the unevenness of the road surface when detecting the road surface, which is conducive to the recording of the detection situation by the detection personnel.

[0034] By adopting the above technical solution, the support frame 11 moves horizontally on the test road surface under the support of the roller 111, while the rotating frame 114 connected to the rotating seat 113 on one end face of the support frame 11 is used to rotate and pull the test piece 1 to move on the test road surface.

[0042] By adopting the above technical solution, the springs 18 that are vertically fixed at both ends of the slide plate 14 generate deformation force, which pushes the slide plate 14 to move vertically on the slide frame 13, making it easy to restore the detection position of the detection wheel 17 during subsequent inspection, thus adapting to the road surface inspection needs of different flatness during use.

[0043] Reference Figure 1 A screw hole 211 is horizontally through the front end face of the guide frame 21, and multiple screw holes 211 are opened in the vertical direction. A locking bolt 212 is horizontally threaded in the screw hole 211 of the guide frame 21.

[0047] The implementation principle of a highway smoothness testing device according to this application embodiment is as follows: During use, the spacing between multiple insulating plates 22 between the two guide frames 21 in the warning component 2 is adjusted according to the error of the road surface smoothness. The spacing between the multiple insulating plates 22 is used to classify the unevenness of the road surface. During use, when the support frame 11 in the testing component 1 moves on the testing road surface, the testing wheel 17 presses against the testing road surface. When the road surface is uneven, when the testing wheel 17 passes through, the testing wheel 17 drives the guide post 15 to slide vertically on the guide cylinder post 12. When the abutment 161 on the top electrical base 16 of the guide post 15 contacts and presses against the electrical contact piece of the warning light 24 on the insulating plate 22, the conductive line of the warning light 24 on the insulating plate 22 is connected, so that the warning light 24 on the insulating plate 22 warns of the unevenness of the road surface.
