Description

Technical Field

[0001] This utility model relates to the field of vehicle testing platform technology, and in particular to a testing platform for rollover protection structures. Background Technology

[0002] Rollover protection structure testing is a passive safety standard used to evaluate and design specialized equipment (such as front loaders, various excavators, and tracked bulldozers) to prevent injury to drivers or operators when vehicles or equipment roll over. Current protection structure testing platforms are not convenient for adjusting the test position. To address this, a test platform for rollover protection structures is proposed, which facilitates the adjustment of the test mechanism's position and allows for testing at multiple locations on the protection structure. Utility Model Content

A crossbeam is bolted to the fixing grooves on the columns. The lateral test components are located on the columns, and the vertical test components are located on the crossbeams. Identical test mechanisms are provided on both the lateral and vertical test components. A control console is mounted at the front end of the base.

[0006] As a further embodiment of this utility model: the testing mechanism includes a movable hinge support, the movable hinge support is provided with a limit structure, a hydraulic cylinder is installed at one end of the movable hinge support via a tension / compression sensor, a connecting plate is installed at the output end of the hydraulic cylinder away from the tension / compression sensor, and the connecting plate is detachable and replaceable.

[0007] As a further improvement of this utility model, the testing mechanism also includes a laser rangefinder sensor, which is mounted on the end of the hydraulic cylinder near the output end via a mounting base, and a reflector is mounted on the end of the connecting plate near the hydraulic cylinder.

[0008] As a further embodiment of this utility model: the lateral testing assembly also includes a screw, and a sliding groove is provided at the middle of the inner side of the column. The screw is rotatably installed in the sliding groove, and the testing mechanism slides on the screw via a lifting slide. A worm gear is installed at the end of the screw, and the worm is rotatably installed on the outer wall of the column via a rotating frame. The worm meshes with the worm gear, and a servo motor is installed on the outer wall of the rotating frame. The output end of the servo motor is connected to the worm.

[0009] As a further embodiment of this utility model: the vertical testing component includes a second servo motor, a groove is provided on the crossbeam, a screw is rotatably installed in the groove of the crossbeam, the second servo motor is installed at one end of the crossbeam, and the output end of the second servo motor passes through the crossbeam and is connected to the screw.

[0010] As a further embodiment of this invention: the vertical test assembly further includes a translation slide, and the test mechanism in the vertical test assembly slides on the screw by using the translation slide.

[0011] As a further improvement of this utility model, the test platform also includes a reinforcing rod for supporting the crossbeam, which is bolted to the connection between the crossbeam and the column.

[0013] The beneficial effects of this utility model are as follows:

[0014] Rotate the hydraulic cylinder and adjust its position. Then, use bolts to connect and fix the connecting plate to the protective frame. During the test, use the hydraulic cylinder to push the connecting plate to compress or stretch the protective frame. During the stretching or pushing of the hydraulic cylinder, the force change is detected by the tension and pressure sensor.

[0015] By setting up a laser rangefinder, the distance the hydraulic cylinder output end moves can be detected, making it easy to record force changes multiple times based on the change in a single movement.

[0016] A servo motor drives a worm gear to rotate, which in turn drives a worm wheel and a screw to rotate, thereby adjusting the height of the test mechanism on the lateral test assembly to facilitate testing of the protection frame at different locations.

[0017] By using a servo motor to drive the screw to rotate and adjust the position of the translation slide, it is convenient to test different positions on the top of the protective frame. Attached Figure Description
