Description

Technical Field

[0001] This utility model relates to the field of axle load technology, specifically to an automobile axle load testing platform. Background Technology

[0002] As a core parameter for measuring vehicle load conditions, accurate detection of vehicle axle load is crucial for road traffic safety, vehicle performance maintenance, and traffic law enforcement. On the one hand, overloaded vehicles exacerbate wear and tear on roads and bridges, shorten the lifespan of infrastructure, and can even lead to serious safety hazards such as road collapses and bridge structural damage. On the other hand, deviations in axle load data can cause decreased vehicle braking performance and abnormal tire wear, directly threatening driving safety.

[0003] Publication No. CN222895801U discloses an automobile axle load testing platform. A socket is provided on the first telescopic rod, and a latch is formed on the side edge of the socket. A second telescopic rod is telescopically connected to the bottom groove of the second testing platform. A plug is provided on the second telescopic rod, and a horizontal groove is formed on the plug. A latch is slidably connected in the horizontal groove. The plug is inserted into the socket, and the latch is engaged in the latch. A top rod is slidably connected in the bottom groove outside the socket, and the top rod is inserted into a corresponding latch. By quickly combining the first and second testing platforms when not in use, the plug of the second testing platform can be inserted into the socket of the first testing platform, thus facilitating the carrying and placement of the platforms by staff. After combination, the testing platforms can be removed all at once, making testing more convenient.

[0004] As shown in the above technical solution, although the device achieves rapid assembly and portable storage of the testing platform, during the use of the device, the surface of the testing platform is prone to deviation of the test data due to the accumulation of dust and debris. For example, when the vehicle tire comes into contact with the dusty platform, the axle load sensor signal may be distorted due to local frictional changes or uneven pressure distribution, affecting the reliability of the test results.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-5 This utility model provides the following two technical solutions: First implementation: A vehicle axle load testing bench, comprising: Test bench 1 is a platform used for testing the axle load of automobiles; Cleaning component 3 is installed at the front end of the testing station 1. Cleaning component 3 includes a mounting frame 31, which is fixedly installed at the front end of the threaded block 43. A battery 32 and a fan 33 are fixedly installed inside the mounting frame 31. The same first air supply pipe 34 is fixedly installed on the top of the mounting frame 31 and the threaded block 43. A connecting pipe 35 is fixedly installed between the fan 33 and the first air supply pipe 34. A second air supply pipe 36 is rotatably installed on the top of the first air supply pipe 34. Multiple jet pipes 37 are evenly installed on the second air supply pipe 36. Cleaning component 3 is used to clean the dust on the top surface of the testing station 1. Drive assembly 4 is installed between the detection table 1 and the cleaning assembly 3. Drive assembly 4 includes a lead screw 41, which is rotatably installed at the front end of the detection table 1. A motor 42 is fixedly installed on the detection table 1. The output end of the motor 42 is fixedly connected to the lead screw 41. A threaded block 43 is threadedly installed on the lead screw 41. A slide groove 44 is opened at the front end of the detection table 1. The threaded block 43 is slidably installed on the slide groove 44. Drive assembly 4 is used to drive the cleaning assembly 3 to slide on the detection table 1. Rotating component 5 is installed between cleaning component 3 and drive component 4. Rotating component 5 includes gear 51, which is fixedly installed on the second air supply pipe 36. A mounting block 52 is slidably installed on the top of threaded block 43. A rack 53 that meshes with gear 51 is fixedly installed on the top of mounting block 52. An electric telescopic rod 54 is fixedly installed on threaded block 43. The output end of electric telescopic rod 54 is fixedly connected to mounting block 52. Rotating component 5 is used to control the rotation of cleaning component 3 on drive component 4 to prevent cleaning component 3 from affecting the normal use of testing station 1.

[0019] When the motor 42 is powered on, it outputs power to drive the lead screw 41 to rotate. Due to the threaded transmission relationship between the lead screw 41 and the threaded block 43, when the lead screw 41 rotates, the threaded block 43 will slide linearly along the axial direction of the lead screw 41 on the slide groove 44 opened at the front end of the detection table 1. The drive assembly 4 provides the power basis for the lateral movement of the cleaning assembly 3. The fan 33 starts under the power supply of the battery 32, draws in air and pressurizes it. The high-pressure air enters the first air supply pipe 34 through the connecting pipe 35, and then is split into multiple jet pipes 37 through the rotating second air supply pipe 36. The jet pipes 37 spray the high-pressure air out at a certain angle and pressure, forming a high-speed airflow. The high-speed airflow acts on the detection. On the surface of the testing platform 1, using aerodynamic principles, dust particles are blown away from the surface of the testing platform 1, achieving the cleaning of dust on the top of the testing platform 1. When the electric telescopic rod 54 extends or retracts, it drives the mounting block 52 to slide on the top of the threaded block 43. The rack 53 on the mounting block 52 meshes with the gear 51 fixed on the second air supply pipe 36. The linear motion of the rack 53 is converted into the rotational motion of the gear 51, which in turn drives the second air supply pipe 36 and the jet pipe 37 to rotate. By controlling the extension length and speed of the electric telescopic rod 54, the angle of the jet pipe 37 can be precisely adjusted. When the cleaning component 3 is not used, it can be rotated to a position that does not affect the normal detection of the axle load of the vehicle on the testing platform 1.

[0020] In this embodiment, dust accumulation alters the contact area and pressure distribution between the vehicle tire and the testing platform 1, leading to inaccurate axle load testing data. The cleaning component 3 utilizes the high-speed airflow ejected from the jet pipe 37 to promptly and thoroughly remove dust from the surface of the testing platform 1, ensuring a flat and clean platform surface. This allows for uniform force distribution during axle load testing, significantly improving the accuracy and reliability of the testing data and effectively preventing misjudgments caused by dust interference. Driven by the drive component 4, the cleaning component 3 can automatically and quickly slide along the surface of the testing platform 1 to complete the cleaning operation. Furthermore, the angle of the jet pipe 37 can be quickly adjusted by rotating the component 5. After cleaning, the component quickly resets, seamlessly connecting to the subsequent axle load testing process. This overcomes the drawbacks of traditional manual cleaning, which requires interrupting testing and is time-consuming, thereby increasing the testing volume per unit time.

[0021] The second implementation differs from the first implementation in that: a mounting rail 6 is fixedly installed on the second air supply pipe 36, and a cleaning plate 7 is movably installed on the mounting rail 6.

[0022] The bottom of the cleaning plate 7 is in contact with the top of the testing station 1.

[0023] Two guide ramps 2 are fixedly installed at both ends of the testing table 1.

[0024] The mounting rail 6 is fixed to the second air supply pipe 36, providing a sliding guide track for the cleaning plate 7. Since the bottom of the cleaning plate 7 is in close contact with the top of the test platform 1, when the drive component 4 drives the cleaning component 3 to slide along the test platform 1, the cleaning plate 7 moves synchronously with the second air supply pipe 36 under the constraint of the mounting rail 6. During the movement, the cleaning plate 7 scrapes off the dust, particles and other impurities remaining on the surface of the test platform 1 through physical friction. At the same time, when the rotation component 5 controls the second air supply pipe 36 to rotate, the cleaning plate 7 also adjusts its angle accordingly to avoid affecting the normal use of the test platform 1. The guide ramps 2 at the left and right ends of the test platform 1 can guide the car tires into the test platform 1.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] After the vehicle leaves the testing platform 1, the rotating assembly 5 is activated, and the electric telescopic rod 54 extends or retracts, causing the mounting block 52 to slide. Through the transmission of the rack 53 and gear 51, the second air supply pipe 36 and the jet pipe 37 are rotated to the cleaning angle, and the cleaning plate 7 is simultaneously adjusted to fit the surface of the testing platform 1. The driving assembly 4 and the cleaning assembly 3 are activated, and the motor 42 drives the threaded block 43 to slide along the testing platform 1. The cleaning assembly 3 reciprocates on the surface of the testing platform 1, and the blower 33 pressurizes the air and sprays out a high-speed airflow through the jet pipe 37, blowing up dust. The cleaning plate 7 slides on the mounting guide rail 6 and removes stubborn stains through physical friction, achieving dual cleaning of "air blowing + scraping". After cleaning is completed, the rotating assembly 5 is activated again to rotate the jet pipe 37 and the cleaning plate 7 to a non-working position to avoid affecting the next vehicle inspection. The equipment enters standby mode, waiting for the next round of cleaning tasks.
