Description

Technical Field

[0001] This utility model relates to the field of tire testing, and in particular to a testing device for the nylon-reinforced structure of engineering tires. Background Technology

[0002] Engineering tires are tires specifically designed and manufactured for engineering vehicles and equipment. They are widely used in construction engineering, mining, metallurgy, forestry and other scenarios, and are mainly equipped on engineering vehicles and engineering machinery. Engineering tires can adapt to various complex terrains and harsh weather conditions, such as mud, gravel, and snow, ensuring the normal operation of engineering vehicles in various environments. Wear resistance testing is an important part of the tire production process. It helps to ensure that tires meet relevant national and industry standards and regulations, and ensures that tires can maintain good performance in actual use. Therefore, each batch of tires produced will be sampled and tested to improve tire safety performance. The testing method generally involves fixing the tire on a high-speed rotating roller and then testing the wear rate of the tire under different loads and speeds.

[0003] Regarding the aforementioned technologies, while traditional testing methods can detect tires by changing their rotation direction, they cannot change the tire's offset direction to simulate the complex stress conditions experienced by tires during actual driving, especially lateral friction. In actual driving, tires experience significant lateral friction when turning, which can lead to different wear patterns. However, traditional testing methods cannot simulate the effects of this lateral friction, thus failing to comprehensively and accurately assess tire wear resistance. This problem may cause discrepancies between test results and actual usage conditions, thereby affecting tire lifespan and safety performance. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a testing device for the nylon-reinforced structure of engineering tires, which facilitates the adjustment of the tire rotation angle and is used to simulate actual driving scenarios such as steering and lateral friction, so as to improve the testing accuracy.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a testing device for the nylon-reinforced structure of engineering tires, comprising: a rolling testing auxiliary component and a gantry frame mounted thereon, wherein the inner side of the gantry frame is provided with a tire fixing mechanism having an angle adjustment function, and further comprising a telescopic rod assembly connected to the top of the gantry frame to drive the tire fixing mechanism to move up and down, wherein the telescopic rod assembly drives the tire fixing mechanism to move down, which is suitable for driving the tire to be tested to roll into contact with the rolling testing auxiliary component;

[0006] The tire fixing mechanism includes an L-shaped connecting seat and a mounting plate. A pressure sensor is located on the top of the mounting plate, and the top of the pressure sensor is connected to the connecting plate. A locking assembly with a rotation function is installed on one side of the L-shaped connecting seat. The mechanism also includes a drive assembly for rotating the L-shaped connecting seat. The drive assembly includes a gear and a slewing bearing disposed between the L-shaped connecting seat and the mounting plate. The gear is meshed with the slewing bearing. A drive motor for rotating the gear is installed on the top side of the mounting plate.

[0007] By adopting the above technical solution, the rolling detection auxiliary component generates axial load through rotational friction to simulate the basic wear of the tire when driving in a straight line. The locking component fixes the tire to be tested to prevent it from shifting or falling off during the test. The pressure sensor measures the pressure when the tire contacts the rolling detection auxiliary component. At the same time, the drive motor drives the slewing bearing to rotate, causing the L-shaped connecting seat to rotate the tire, thereby changing the tire's contact angle and replicating the lateral friction force generated by the turning and U-turn of the engineering vehicle. This simulates the force on the tire in different directions during actual driving. The telescopic rod component adjusts the telescopic length to change the contact pressure between the tire and the rolling detection auxiliary component, thereby simulating different test conditions.

[0008] In a preferred embodiment, the present invention can be further configured such that: the locking assembly includes a mounting base connected to an L-shaped connecting seat, one end of the mounting base is rotatably connected to an air shaft, and a second drive motor is connected to the side of the L-shaped connecting seat away from the air shaft, and the output shaft of the second drive motor is connected to the air shaft.

[0009] By adopting the above technical solution, the mounting base serves as the support structure for the locking assembly and is connected to the L-shaped connecting base, providing a stable mounting foundation for the air shaft. The air shaft expands and contracts through changes in internal air pressure, thereby clamping the tire. The second drive motor drives the air shaft to rotate, thereby rotating the tire to be tested, and cooperates with the rolling detection auxiliary component to perform wear resistance testing.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the telescopic rod assembly includes guide rods that pass through the top of the gantry frame and are respectively connected to the top periphery of the mounting plate; guide sleeves installed on the top of the gantry frame are respectively fitted on the guide rods; a hydraulic cylinder is connected to the center of the top of the gantry frame; and the extended end of the hydraulic cylinder is connected to the mounting plate.

[0011] By adopting the above technical solution, under the guidance of the guide rod and in conjunction with the guide sleeve, the mounting plate can move smoothly up and down along the predetermined trajectory, avoiding detection errors caused by shaking or deviation. The hydraulic cylinder is connected to the top center of the gantry, providing power for the up and down movement of the mounting plate, and adjusting the height of the mounting plate as needed, thereby changing the contact pressure between the tire and the rolling detection auxiliary component.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the rolling detection auxiliary component includes an auxiliary platform and a detection roller rotatably connected to its inner side; the top of the auxiliary platform is provided with a clearance opening; the top end of the outer circle of the detection roller is located inside the clearance opening and above the clearance opening; a drive motor three for driving the detection roller to rotate is connected to one side of the auxiliary platform; the rotation direction of the detection roller is opposite to the rotation direction of the air shaft.

[0013] By adopting the above technical solution, the outer circle of the detection roller contacts the tire, simulating the rolling state of the tire during actual driving. Furthermore, the rotation direction of the detection roller driven by the three-drive motor is opposite to the direction of the air shaft, that is, the rotation direction of the detection roller is opposite to the rotation direction of the tire being detected, which can more comprehensively evaluate the tire's wear resistance performance.

[0014] In a preferred embodiment, the present invention can be further configured such that the radius of the detection roller is greater than the distance from the center of the air shaft to the inner top of the L-shaped connecting seat, and the length of the detection roller is greater than the width of the air shaft.

[0015] By adopting the above technical solution, increasing the roller radius can expand the contact arc length between the tire and the roller, covering more tread areas, such as the tire shoulder and tire crown, improving the comprehensiveness of wear detection, and ensuring that the tire can fully contact the detection roller during the detection process even after the tire angle is adjusted.

[0016] In summary, the present invention provides at least one of the following beneficial technical effects of the testing equipment for engineering tire nylon reinforcement structures:

[0017] 1. The drive motor drives the slewing bearing to rotate, which in turn causes the L-shaped connecting seat to rotate the tire, thereby changing the tire's contact angle. Combined with the reverse rotation of the detection roller, this accurately reproduces the differential effect and lateral sliding friction when the vehicle is turning, thus simulating the force on the tire in different directions during actual driving and improving detection accuracy.

[0018] 2. The telescopic rod assembly moves vertically up and down, driving the tire fixing mechanism to move downward and adjust the axial load, so as to simulate the load gradient change of engineering vehicles from empty to full load and from flat road surface to steep slope operation. It also works with the drive assembly to simulate lateral force, reproduce the multi-directional force state of the tire in actual driving, and further improve the accuracy of detection.

[0030] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] Reference Figure 1-3This utility model discloses a testing device for an engineering tire with nylon reinforcement structure, comprising: a rolling testing auxiliary component 10 and a gantry frame 2 mounted above it; a tire fixing mechanism 30 with angle adjustment function is provided on the inner side of the gantry frame 2; a telescopic rod assembly 40 connected to the top of the gantry frame 2 to drive the tire fixing mechanism 30 to move up and down; the telescopic rod assembly 40 drives the tire fixing mechanism 30 to move downward, suitable for causing the tire to be tested to roll into contact with the rolling testing auxiliary component 10; the tire fixing mechanism 30 includes an L-shaped connecting seat 31 and a mounting plate 32; a pressure sensor 35 is located on the top of the mounting plate 32; a connecting plate 36 is connected to the top of the pressure sensor 35; a locking component 33 with rotation function is installed on one side of the L-shaped connecting seat 31; and a driving component 34 for driving the L-shaped connecting seat 31 to rotate; the driving component 34 includes a gear 341 and a slewing bearing 342 disposed between the L-shaped connecting seat 31 and the mounting plate 32; the gear 341 and the slewing bearing 342 are meshed together. A drive motor 343 for rotating a drive gear 341 is mounted on one side of the top of the mounting plate 32. The locking assembly 33 includes a mounting base 331 connected to an L-shaped connecting seat 31. An air shaft 332 is rotatably connected to one end of the mounting base 331. A second drive motor 333 is connected to the side of the L-shaped connecting seat 31 away from the air shaft 332. The output shaft of the second drive motor 333 is connected to the air shaft 332. The rolling detection auxiliary assembly 10 includes an auxiliary platform 11 and a detection roller 1 rotatably connected to its inner side. 2. The top of the auxiliary platform 11 is provided with a clearance opening 13. The top of the outer circle of the detection roller 12 is located inside the clearance opening 13 and above the clearance opening 13. A drive motor 314 for driving the detection roller 12 to rotate is connected to one side of the auxiliary platform 11. The rotation direction of the detection roller 12 is opposite to the rotation direction of the air shaft 332. The radius of the detection roller 12 is greater than the distance from the axis of the air shaft 332 to the top of the inner side of the L-shaped connecting seat 31, and the length of the detection roller 12 is greater than the width of the air shaft 332.

[0032] Drive motor 1 (343), drive motor 2 (333), and drive motor 3 (14) are all servo motors. After the tire and rim to be tested are matched and inflated, they are assembled onto the air shaft 332. The air shaft 332 is inflated to fix the tire in place, and the telescopic rod assembly 40 drives the tire downward, bringing it into contact with the detection roller 12. At the same time, the pressure sensor 35 measures the pressure when the tire contacts the rolling detection auxiliary assembly 10, which is used to evaluate the tire's rolling resistance, pressure distribution, and other performance characteristics. Under the action of drive motor 3 (14), the rotation direction of the detection roller 12 is aligned with the rotation direction of the air shaft 332. Conversely, the rolling state of the tire during actual driving is simulated. In addition, the drive motor 343 drives the gear 341 to rotate the slewing bearing 342, causing the L-shaped connecting seat 31 to rotate the tire, thereby changing the tire's contact angle and replicating the lateral friction force generated by the turning and U-turn of the engineering vehicle. This simulates the force situation of the tire in different directions during actual driving. The length of the detection roller 12 is greater than the width of the air shaft 332, which can ensure that the tire can fully contact the detection roller 12 during the detection process even after the tire angle is adjusted, thereby improving the detection accuracy.

[0033] The telescopic rod assembly 40 includes guide rods 41 that pass through the top of the gantry frame 2 and are respectively connected to the top periphery of the mounting plate 32. Guide sleeves 42 installed on the top of the gantry frame 2 are respectively fitted on the guide rods 41. A hydraulic cylinder 43 is connected to the center of the top of the gantry frame 2. The extended end of the hydraulic cylinder 43 is connected to the mounting plate 32.

[0034] The cooperation between the guide rod 41 and the guide sleeve 42 ensures that the mounting plate 32 will not wobble or shift during its up-and-down movement, thus guaranteeing the accuracy and stability of the tire fixing mechanism 30. The hydraulic cylinder 43 provides power for the up-and-down movement of the mounting plate 32 and adjusts the height of the mounting plate 32 as needed, thereby changing the contact pressure between the tire and the detection roller 12.

[0035] The implementation principle of this embodiment is as follows: During use, the tire to be tested is mounted on the corresponding wheel hub and inflated to a suitable pressure. It is then mounted on the air shaft 332, and the air nozzle at one end of the air shaft 332 is inflated to lock and fix the tire to be tested. Subsequently, the hydraulic cylinder 43 drives the mounting plate 32 downwards, causing the inflated tire to contact the testing roller 12. Simultaneously, the drive motor 14 rotates the testing roller 12, with the rotation direction of the testing roller 12 opposite to that of the tire, simulating the rolling state of the tire during actual driving and evaluating the tire's performance. In addition to its wear resistance, the hydraulic cylinder 43 can further adjust the tire height to regulate the contact pressure between the tire and the detection roller 12, simulating the ground pressure change of an engineering vehicle from unloaded to fully loaded. At the same time, the drive motor 343 can drive the gear 341 to rotate the slewing bearing 342, causing the L-shaped connecting seat 31 to rotate the tire, thereby changing the tire's contact angle and replicating the lateral friction force generated by the turning and U-turn of the engineering vehicle. This simulates the force situation of the tire in different directions during actual driving, further improving the comprehensiveness and accuracy of tire detection.
