Description

Technical Field

[0001] This utility model relates to the field of axle (bridge) testing technology, and in particular to a multi-functional integrated testing platform. Background Technology

[0002] With the ever-increasing demand in the trailer market, trailer axles have also ushered in a new stage of technological innovation and development. Axle load refers to the weight borne by the axle. For small cars, there are two sets of parameters: front and rear loads. For heavy-duty trucks, which have more axles, there are multiple sets of parameters. To prevent improper assembly or missing parts, axle load testing is required before leaving the factory to ensure safety during road use.

[0003] A search revealed a vehicle axle load testing platform under publication number CN117191260A. This platform includes a ramp, a support platform, a ranging mechanism, and a central control unit. The ramp is equipped with a guiding mechanism, each including a lead screw, a guide sleeve, an adjusting ring, an outer guide plate, and an inner guide plate. The threads of the lead screw, guide sleeve, and adjusting ring in the two guiding mechanisms are opposite in direction, and the inner ends of the two lead screws are fixedly connected. The support platform has multiple grooves, each containing two parallel guide posts and an adjusting plate. Pressure sensors are mounted on the surface of the adjusting plates, and the detection ends of two pressure sensors located within the same adjusting plate are connected to a bearing plate. The ranging mechanism is located outside the grooves, and the number of ranging mechanisms corresponds to the number of grooves. This invention is applicable to axle load testing of vehicles of different widths.

[0004] Although the above solution adjusts the position of the inner guide plate in the two sets of guide mechanisms by rotating the lead screw, thus enabling it to be used for axle load testing of vehicles of different widths, it cannot adjust the position of the load test leaf spring block according to the length of the axle and the actual leaf spring mounting position of the axle. Therefore, we propose a multi-functional integrated test platform. Utility Model Content

[0005] The main purpose of this utility model is to provide a multifunctional integrated test platform. By setting up a hoisting unit and a test unit, it solves the problem that it cannot adjust the position of the leaf spring block for load testing based on the actual leaf spring installation position of the axle according to the length of the axle.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-functional integrated test platform includes a base unit, a hoisting unit and a test unit disposed above the base unit, wherein the hoisting unit is located above the test unit;

[0008] The hoisting unit includes two columns installed on the top of the base unit, fixed seats installed on the top of the columns, a threaded rod movably disposed between the two fixed seats, a movable part installed on the periphery of the threaded rod, a first drive motor installed on the input end of the threaded rod, and a hoisting component disposed on the side of the movable part.

[0009] The test unit includes a crossbeam seat installed between two columns, a load cylinder movably installed inside the crossbeam seat, a spring hanger installed at the telescopic end of the load cylinder, an adjustment component located at the bottom of the spring hanger, a bearing component located below the adjustment component, and a reset spring with one end fixedly connected to the load cylinder and the other end fixedly connected to the spring hanger.

[0010] Preferably, the base unit includes a platform base, a hydraulic cylinder installed on the inner bottom wall of the platform base, and a floating platform installed on the telescopic end of the hydraulic cylinder.

[0011] Preferably, the base unit further includes a mounting groove formed on the top of the floating platform, and a road condition simulation tray disposed within the mounting groove.

[0012] Preferably, the lifting component includes a lifting base mounted on the side wall of the moving component, a lifting motor mounted on the top of the moving component, and a lifting hook and cable mounted on the lifting base.

[0013] Preferably, the hoisting unit further includes a guide rod installed between the two columns and movably passing through the moving part.

[0014] Preferably, the adjusting component includes a locking screw installed at the bottom of the spring mounting plate, a locking nut movably installed on the side wall of the locking screw, a handwheel movably installed on the periphery of the locking screw, and a hydraulic cylinder pressure head installed at the bottom of the handwheel.

[0015] Preferably, the load-bearing component includes a load-transfer beam disposed below the cylinder head, an adjusting groove formed at the bottom of the load-transfer beam, a leaf spring block disposed in the adjusting groove, and a locking bolt disposed between the adjusting groove and the leaf spring block.

[0016] Preferably, the test unit further includes a lug mounted on the top of the load transfer beam.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, by setting up a hoisting unit and a testing unit, when it is necessary to adjust the position of the load test leaf spring block according to the length of the axle, the distance between the two road condition simulation trays of the asphalt pavement is adjusted (the wheel track is adjusted by the installation position of the installation groove of the floating platform). Then, the hoisting unit is used to hoist the axle to be tested to a suitable position, and the load transfer beam is placed on the axle of the axle. By loosening the locking bolts, the leaf spring block moves in the adjustment groove until the position of the leaf spring block is tightly fitted with the leaf spring seat of the axle. This realizes the adjustment of the position of the load test leaf spring block according to the length of the axle and the actual leaf spring installation position of the axle. When it is necessary to perform a load test on the axle, after the position adjustment of the test leaf spring block is completed, the handwheel at the bottom of the load cylinder is rotated to make the cylinder head contact the load transfer beam. Then, the locking nut is rotated to lock it. Subsequently, the extension end of the load cylinder extends, so that the load transfer beam performs a load test on the axle.
