Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, specifically to an auxiliary structure for inspecting vehicles. Background Technology

[0002] In the field of vehicle safety inspection, parking brake performance testers are key equipment for evaluating the reliability of vehicle parking brake systems. They accurately determine parking brake performance by applying a pulling force to the vehicle and detecting relevant parameters. However, existing parking brake performance testers have certain limitations in practical applications: their effective test stroke is limited by the length of the sensor cables. This makes the accuracy of the parking position extremely important during parking brake testing. Operators need to repeatedly adjust the vehicle's parking position to ensure effective coordination between the tester's pulling components and the vehicle, increasing operational complexity, prolonging the testing time for a single vehicle, and reducing overall testing efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an auxiliary structure for vehicle detection, in which the sensor is fixedly positioned, thus eliminating the limitation on the length of the traction cable and reducing the risk of sensor cable damage.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an auxiliary structure for vehicle testing, comprising: a platform; a lifting plate, the lifting plate being slidably disposed on the platform; a winch, the winch being mounted on the lifting plate; and a traction assembly, the traction assembly comprising a first steel wire rope wound on the winch, the first steel wire rope having a movable pulley and a plate ring tension / compression sensor connected thereto after the first steel wire rope passes over the movable pulley, the other end of the plate ring tension / compression sensor being connected to a second steel wire rope fixedly connected to the lifting plate, and a cable connected to the vehicle to be tested being connected to the movable pulley.

[0005] Preferably, the platform includes a base and a support frame, the support frame being vertically fixed at one end of the base, and the support frame having a U-shaped structure.

[0006] Preferably, the lifting plate has limiting grooves on both sides that are adapted to the support frame, and the lifting plate slides up and down along the support frame through the limiting grooves.

[0007] Preferably, a reinforcing rod is fixedly connected between the support frame and the base.

[0008] Preferably, the support frame is provided with an adjusting screw that is threadedly connected to the lifting plate, and the end of the adjusting screw away from the lifting plate is provided with a handwheel or a motor.

[0009] With the above structure, this utility model has the following advantages:

[0010] The plate ring tension / compression sensor in this application is fixedly connected to the lifting plate via a second steel wire rope, maintaining a stable position and eliminating the need for movement during the pulling process. This avoids the limitation of the test stroke caused by the sensor cable length in traditional structures, significantly increasing the effective test range, reducing the accuracy requirements for vehicle parking position, minimizing the hassle of repeated vehicle adjustments by operators, and improving the testing efficiency of a single vehicle. Because the sensor position is fixed, its connecting cable does not need to repeatedly extend, bend, or rub during the pulling action, reducing problems such as wear and breakage caused by mechanical stress and extending the cable's service life. The movable pulley in the pulling assembly can distribute the pulling force using mechanical principles, reducing the driving force required by the winch and lowering the winch's workload. This not only saves energy but also reduces wear on equipment components, extends the service life of core components such as the winch, and improves the overall structural operational stability.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0018] Combined with appendix Figures 1-2 An auxiliary structure for vehicle inspection includes a platform 1, a lifting plate 8, a winch 2, and a traction assembly.

[0019] The lifting plate 8 is slidably mounted on the platform 1; the winch 2 is mounted on the lifting plate 8; the traction assembly includes a first steel wire rope 3 wound on the winch 2, a movable pulley 5 is provided on the first steel wire rope 3, and a plate ring tension and compression sensor 4 is connected to the first steel wire rope 3 after passing over the movable pulley 5. The other end of the plate ring tension and compression sensor 4 is connected to a second steel wire rope 7 fixedly connected to the lifting plate 8, and a cable 6 connected to the vehicle to be tested is connected to the movable pulley 5.

[0020] In one embodiment of this utility model, an adjusting screw 9, which is threadedly connected to the lifting plate 8, is rotatably provided on the platform 1. Specifically, as shown... Figure 1 As shown, the two ends of the adjusting screw 9 are rotatably connected to the platform 1. The connection method can be a bearing connection to ensure that the adjusting screw 9 can rotate flexibly. The lifting plate 8 is provided with a threaded hole that matches the adjusting screw 9. The adjusting screw 9 passes through the threaded hole. When the adjusting screw 9 is rotated, the lifting plate 8 can slide up and down along the height direction of the platform 1 under the action of the thread, thereby realizing the adjustment of the height of the lifting plate 8. With this setting, the position of the lifting plate 8 can be flexibly adjusted according to the parking brake traction point height of different vehicles under test to ensure effective cooperation between the traction component and the vehicle.

[0021] In summary, when using the auxiliary structure for vehicle testing of this utility model, firstly, according to the specific situation of the vehicle to be tested, the lifting plate 8 is adjusted to a suitable height by rotating the adjusting screw 9. Then, the cable 6 on the movable pulley 5 is connected and fixed to the vehicle to be tested. The winch 2 is started, and the winch 2 winds or releases the first steel wire rope 3. Under the action of the first steel wire rope 3, the movable pulley 5 drives the cable 6 to apply a pulling force to the vehicle. During this process, the plate ring tension and compression sensor 4 can detect the magnitude of the tension in real time. Since the plate ring tension and compression sensor 4 is fixedly connected to the lifting plate 8 through the second steel wire rope 7, its position remains stable and will not move due to the pulling action, thereby removing the limitation on the length of the traction rope and avoiding... To prevent sensor cables from being damaged due to frequent movement, the movable pulley 5 utilizes mechanical principles to distribute the pulling force, reducing the load on the winch 2. For example, the maximum measurement range of the traditional plate ring tension sensor 4 is 9800 daN. In this application, while maintaining the maximum measurement range of 9800 daN, the maximum measurement range of the plate ring tension sensor 4 is reduced to half of the original, i.e., 4900 daN, making the entire pulling process more stable and reliable. Without increasing the pulling force of the winch 2, the measurement range of the equipment can be increased simply by increasing the number of pulleys. This auxiliary structure can adapt to the detection needs of different vehicle models, reducing the time and effort required for operators to adjust the vehicle parking position, and effectively improving the efficiency and accuracy of vehicle detection.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
