Description

Technical Field

[0001] This utility model relates to the field of road surface inspection technology, and in particular to a road surface smoothness inspection vehicle. Background Technology

[0002] Smoothness is one of the important indicators of road construction quality and service level. Uneven road surfaces increase driving resistance and cause additional vibrations to vehicles. This vibration causes bumpy driving, affecting driving speed and safety, driving smoothness, and passenger comfort. At the same time, vibration also exerts impact force on the road surface, thereby accelerating road and vehicle damage and tire wear. Uneven road surfaces will also trap rainwater, accelerating road surface deterioration. Therefore, the detection and evaluation of smoothness is a very important part of highway construction and maintenance.

[0003] Reference Figure 6 The diagram shows a hand-push type road surface evenness tester in the prior art. The test instrument box is close to the ground, and the operation panel is located on top of the test instrument box. During use, the operator needs to squat down to control the tester and read data, which causes inconvenience to the test process. Utility Model Content

[0004] To facilitate operators in using testing instruments to inspect road surface smoothness, this application provides a road surface smoothness inspection vehicle.

[0005] The road surface smoothness inspection vehicle provided in this application adopts the following technical solution: A road surface smoothness testing vehicle includes a vehicle body, an instrument box, a testing instrument, and an operation panel. The instrument box is fixedly connected to the vehicle body, and the testing instrument is installed inside the instrument box. It also includes a lifting platform, multiple sets of telescopic rods, and a drive assembly. The lifting platform is slidably connected to the vehicle body, and the operation panel is mounted on the lifting platform. Both ends of the multiple sets of telescopic rods are fixedly connected to the vehicle body and the lifting platform, respectively. Each set of telescopic rods has several connecting rods fixedly connected to it, and the other ends of the connecting rods are fixedly connected to adjacent telescopic rods. The drive assembly drives one set of telescopic rods to extend and retract. An extension platform is rotatably connected to the lifting platform. One end of a support rod is slidably connected to the extension platform. The lifting platform has a slot, and when the extension platform rotates to its extended state, the other end of the support rod can engage with the slot.

[0006] By adopting the above technical solution, the height of the operating panel can be adjusted via the lifting platform to suit different heights or testing scenarios. Multiple sets of telescopic rods with connecting rods support the lifting platform while enhancing structural stability. The extended platform expands the operating space and, through the insertion of support rods and slots, maintains stability in the extended state, assisting workers in performing related operations and facilitating the use of testing instruments to inspect road surface flatness.

[0007] Preferably, the lifting platform is provided with a push-pull handrail, and a hand support plate is slidably connected to the lifting platform. The hand support plate can slide above the push-pull handrail and abut against the push-pull handrail.

[0008] By adopting the above technical solution, the push-pull handrail facilitates the movement of the lifting platform by personnel. The hand support plate can slide above the handrail, which can serve as an auxiliary support for the elbow, or place tools, temporary documents, etc., making it more convenient for the inspection personnel to operate, reducing the burden on their hands during operation, and making it easier for the operator to operate the control panel and use the inspection instrument to detect the road surface flatness.

[0009] Preferably, the extension platform is provided with an anti-slip rubber pad, and when the extension platform is rotated to the storage state, the anti-slip rubber pad is positioned opposite to the detector.

[0010] By adopting the above technical solution, the extension platform is equipped with anti-slip rubber pads, which can prevent items placed on the platform from slipping and improve safety. When in the storage state, the anti-slip rubber pads face the detector, and also play a role in dust prevention and cushioning, reducing the possibility of the extension platform colliding with the detector and damaging it during storage.

[0011] Preferably, each group of telescopic rods includes several sleeves with different diameters and coaxial arrangement. The sleeves with smaller diameters are sequentially slidably connected inside the sleeves with relatively larger diameters. The sleeves with the largest diameter are fixedly connected to the vehicle body, and the sleeves with the smallest diameter are fixedly connected to the lifting platform. The drive assembly is used to drive the sleeves to slide synchronously.

[0012] By adopting the above technical solution, the telescopic rod is constructed by coaxial sliding of multi-diameter sleeves, resulting in a compact structure that allows for a large lifting stroke. Utilizing the diameter difference to achieve extension and retraction ensures a stable and smooth process, effectively supporting the lifting platform and the items on it.

[0013] Preferably, the drive assembly includes a plurality of threaded cylinders and a motor. The plurality of threaded cylinders correspond to a plurality of sleeves. The plurality of threaded cylinders have different diameters and are coaxially arranged. The threaded cylinders with smaller diameters are sequentially slidably connected to the threaded cylinders with relatively larger diameters. The plurality of threaded cylinders are rotatably connected to the corresponding sleeves and are threadedly connected to the sleeves with relatively smaller diameters on the inner side of the corresponding sleeves. The motor is used to drive the rotation of the bottommost threaded cylinder.

[0014] By adopting the above technical solution, relying on the drive scheme of the threaded cylinder and the motor, the motor drives the bottom threaded cylinder to rotate, and the threaded engagement drives the other sleeves to slide synchronously, achieving lifting and lowering. This design can precisely control the lifting height, and the threaded drive has self-locking properties, which can prevent the lifting platform from accidentally falling due to external forces or gravity, thus improving the safety of use.

[0015] Preferably, it also includes several data cables, which are used to realize electrical connection and data transmission between the detector and the operation panel. Each of the several sleeves of a set of telescopic rods has a wire hole at both ends. Rubber retaining rings are fixedly connected to the wire holes on the side near the vehicle body and the side near the lifting platform. The several data cables pass through the several wire holes at the same time, and the two ends of the several data cables are respectively located in two rubber retaining rings. The inner wall of the rubber retaining rings is in close contact with the several data cables.

[0016] By employing the above technical solution, data cables can be routed through wire holes to prevent clutter and avoid external interference or damage. Rubber retaining rings secure both ends of the data cable, preventing it from loosening or detaching during platform movement and ensuring stable data transmission between the testing instrument and the control panel.

[0017] Preferably, a storage cavity is provided at the connection between two adjacent sleeves, the storage cavity is connected to the wire hole, and the data cable can be stored in the storage cavity.

[0018] By adopting the above technical solution, the data cable storage cavity can accommodate excess data cables when the lifting platform descends, preventing data cables from being damaged by squeezing or bending, and also playing the role of maintaining stable data transmission.

[0019] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model features an adjustable control panel height via a lifting platform, catering to different heights or inspection scenarios. Multiple sets of telescopic rods with connecting rods support the lifting platform while enhancing structural stability. The extended platform expands the operating space and, through the interlocking of the support rods and slots, maintains stability in the extended state, assisting workers in performing related operations and facilitating the use of inspection instruments to test road surface flatness. 2. The push-pull handrail of this utility model facilitates the movement of the lifting platform by personnel. The hand support plate can slide to the top of the handrail, which can serve as an auxiliary support for the elbow or place tools, temporary documents, etc., making it more convenient for the testing personnel to operate, reducing the burden on their hands during operation, and making it easier for the operator to operate the control panel and use the testing instrument to test the road surface flatness. 3. This utility model utilizes wire-through holes to lay data cables, preventing messy wiring and avoiding external interference or damage. Rubber retaining rings secure both ends of the data cable, preventing it from loosening or detaching due to platform movement, thus ensuring stable data transmission between the detector and control panel.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0028] This application discloses a road surface smoothness inspection vehicle.

[0029] Reference Figure 1 and Figure 2This embodiment describes a road surface evenness testing vehicle, comprising a vehicle body 1, an instrument case 2, a testing instrument, and an operation panel 4. The instrument case 2 is fixedly connected to the vehicle body 1, and the testing instrument is installed inside the instrument case 2. It can collect road surface evenness data in real time. The testing instrument is existing technology and is separately installed in the instrument case 2. Three wires—a displacement sensor, a distance sampling head, and a battery—are connected to the instrument case 2 and can be easily disassembled and reassembled. The electrical components of this instrument are based on an 8031 ​​microprocessor, supplemented by an electronic latch, data memory, program memory, and decoding circuit, along with appropriate logic circuits. The microprocessor used in this instrument has better anti-interference capabilities than commonly used microprocessors, and the power supply is provided by a battery, making it highly suitable for field quality testing in highway engineering. All voltages required by the entire instrument are provided by a DC / DC conversion module and a precision voltage regulator circuit.

[0030] Reference Figure 1 and Figure 2 It also includes a lifting platform 16, four sets of telescopic rods 17, and a drive assembly 18. The lifting platform 16 is slidably connected to the vehicle body 1. The operation panel 4 is installed on the lifting platform 16. The operation panel 4 integrates functions such as data display and parameter adjustment. The two ends of the four sets of telescopic rods 17 are respectively fixedly connected to the vehicle body 1 and the lifting platform 16. Several connecting rods 19 are fixedly connected to each set of telescopic rods 17. The other ends of the connecting rods 19 are respectively fixedly connected to adjacent telescopic rods 17, forming a multi-set linkage support structure. The drive assembly 18 is used to drive one set of telescopic rods 17 to perform telescopic movement. Through the connecting rods 19, multiple sets of telescopic rods 17 can perform telescopic movement together.

[0031] Reference Figure 2 and Figure 3 One side of the lifting platform 16 is rotatably connected to an extension platform 21 via a hinge. The extension platform 21 can rotate around the hinge axis to achieve unfolding and storage. The support rod 22 is slidably connected to the extension platform 21. The corresponding position of the lifting platform 16 is provided with a slot 23 that engages with the support rod 22. When the extension platform 21 rotates to a horizontal extension state with the lifting platform 16, the other end of the support rod 22 can rotate downward to engage with the slot 23.

[0032] Reference Figure 1 and Figure 2The height of the operating panel 4 can be adjusted via the lifting platform 16 to suit different heights or testing scenarios. Four sets of telescopic rods 17 with connecting rods 19 form a mesh support system. While bearing the weight of the lifting platform 16 and the equipment it carries, these rods effectively distribute stress, reducing swaying or tilting during lifting. This supports the lifting platform 16 and enhances structural stability. The extension platform 21 expands the operating space and, through the insertion of the support rods 22 and slots 23, maintains stability in the extended state, assisting workers in performing related operations and facilitating the use of testing instruments to inspect road surface flatness.

[0033] Reference Figure 4 and Figure 5 Each telescopic rod 17 includes several sleeves 24 of different diameters, coaxially arranged. Smaller diameter sleeves 24 slide sequentially within larger diameter sleeves 24. The largest diameter sleeve 24 is fixedly connected to the vehicle body 1, and the smallest diameter sleeve is fixedly connected to the lifting platform 16. The drive assembly 18 drives the sleeves 24 to slide synchronously. The telescopic rod 17, composed of coaxially sliding sleeves 24 of multiple diameters, has a compact structure and can achieve a large lifting stroke. Utilizing diameter differences for extension and retraction ensures a stable and smooth process, effectively supporting the lifting platform 16 and the items on it.

[0034] Reference Figure 4 The drive assembly 18 employs a combination of threaded drive and motor 26. The drive assembly 18 includes several threaded cylinders 25 and a motor 26. Each threaded cylinder 25 corresponds to a sleeve 24. The threaded cylinders 25 have different diameters and are coaxially arranged. The smaller diameter threaded cylinders 25 are sequentially slidably connected to the larger diameter threaded cylinders 25. Each threaded cylinder 25 is rotatably connected to its corresponding sleeve 24 and threadedly connected to the smaller diameter sleeve 24 inside the corresponding sleeve 24. The largest diameter threaded cylinder 25 is rotatably connected to the smallest diameter sleeve 24, and vice versa. The motor 26 drives the rotation of the bottommost threaded cylinder 25. Gears 20 are coaxially and fixedly connected to the output shaft of the motor 26 and the bottommost threaded cylinder 25, respectively. The two gears 20 mesh with each other. The operation panel 4 is used to control the starting, stopping, forward, and reverse rotation of the motor 26. This drive system relies on the threaded cylinders 25 and the motor 26. Motor 26 drives the bottom threaded cylinder 25 to rotate, and the threaded engagement causes all sleeves 24 to slide synchronously, achieving lifting and lowering. This design can precisely control the lifting height, and the threaded transmission has self-locking properties, which can reduce the possibility of the lifting platform 16 accidentally falling due to external forces or gravity, thus improving the safety of use.

[0035] Reference Figure 1 and Figure 5It also includes several data cables 27, which are used to achieve electrical connection and data transmission between the detector and the control panel 4. Each end of one set of telescopic rods 17 has a threading hole 28. Rubber retaining rings 29 are fixedly connected to the threading holes 28 on the side near the vehicle body 1 and the side near the lifting platform 16. The data cables 27 pass through the threading holes 28 simultaneously, with each end of the data cable 27 located within two rubber retaining rings 29. The inner wall of the rubber retaining rings 29 is tightly attached to the data cables 27. Using the threading holes 28 to route the data cables 27 prevents messy wiring and avoids external interference or damage to the wiring. The rubber retaining rings 29 secure the ends of the data cables 27, preventing them from loosening or detaching due to platform lifting, ensuring stable data transmission between the detector and the control panel.

[0036] Reference Figure 5 A storage cavity 30 is provided at the connection point of two adjacent sleeves 24. The storage cavity 30 is connected to the wire hole 28, and the data cable 27 can be stored in the storage cavity 30. When the lifting platform 16 descends, the excess data cable 27 can be naturally stored in the storage cavity 30; when it rises, the data cable 27 in the storage cavity 30 is gradually released, effectively avoiding damage such as squeezing and bending of the data cable 27 due to changes in length, and further ensuring the continuity of data transmission.

[0037] Reference Figure 1 and Figure 2 The lifting platform 16 is equipped with a push-pull handrail 31. A slide rail 32 is located below the control panel 4 of the lifting platform 16, and a drawer-type hand support 33 is slidably connected to the slide rail 32. The hand support 33 can slide above the push-pull handrail 31 and rest against it. The push-pull handrail 31 facilitates the movement of the lifting platform 16 and provides leverage for operators when moving the vehicle body 1. The hand support 33 can slide above the handrail, serving as an auxiliary support for the elbow or a place to hold tools, temporary documents, etc., making operation more convenient for inspectors, reducing hand strain, and facilitating the operation of the control panel and the use of the testing instrument to inspect the road surface smoothness.

[0038] Reference Figure 2 and Figure 3 An anti-slip rubber pad 34 is fixedly connected to the surface of the extension platform 21. When the extension platform 21 is rotated to the storage state, the anti-slip rubber pad 34 is positioned opposite the detector. The anti-slip rubber pad 34 on the extension platform 21 prevents items placed on the platform from slipping, improving safety. In the storage state, the anti-slip rubber pad 34 faces the detector, also providing dust protection and cushioning, reducing the possibility of the extension platform 21 colliding with the detector and damaging it during storage.

[0039] Reference Figure 1 and Figure 2Through the above structural design, this embodiment enables the road surface smoothness inspection vehicle to have features such as adjustable height, convenient operation, stable structure, and stable data transmission, thereby improving inspection efficiency and equipment lifespan, and making it easier for operators to use the inspection instrument to inspect the road surface smoothness.

All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
