Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of lifting device testing for multi-functional transport vehicle body subsystem of tracked airborne combat vehicles, specifically involving the connection method between the lifting device and the test platform in the test of the vehicle lifting device. Background Technology
[0002] The lifting device of the multi-functional transporter body subsystem of a certain tracked airborne combat vehicle plays a crucial role in the overall function of the vehicle. The stability of the lifting device greatly affects the vehicle's functionality and, more importantly, determines the quality of its performance support in actual combat.
[0003] Functional testing of the lifting system must be completed before it is installed on the vehicle. This is crucial for two reasons: firstly, ensuring the lifting system operates normally; and secondly, preventing the uncertainty of the lifting test results from affecting the vehicle body. If testing is conducted directly on the actual vehicle, disassembly of the lifting device would be necessary if some functions were found to be malfunctioning, incurring significant costs. Furthermore, it places high technical demands on the assembly operators.
[0004] Currently, the lifting system is tested by directly mounting the equipment, which poses certain safety hazards.
[0005] 1) Uncertainty in the test results of the lifting system may cause unknown damage to the vehicle.
[0006] 2) During the actual vehicle lifting test, the operating status of the lifting system could not be directly observed due to obstruction by other components.
[0007] To avoid damage to the vehicle itself due to the uncertainty of the lifting device test results during the actual vehicle loading test, and since the test bench cannot be directly connected to the lifting device for testing, a clamping device required for the test process is designed to ensure the smooth conduct of the lifting test and reduce the difficulty of the actual vehicle loading test and the risk of damage to the vehicle body. Utility Model Content
[0008] The technical problem this utility model aims to solve is to provide a clamping body for a lifting device test bench, enabling the connection between the lifting device and the test platform. This achieves the goals of stability, safety, economy, reliability, and ease of operation in the lifting device testing process and results.
[0009] The invention is a fixture for a lifting device test bench. It belongs to the technical field of lifting device testing for multi-functional transport vehicle body subsystem of tracked airborne combat vehicles, and specifically relates to the connection method of the lifting device on the test platform in the lifting device test of the vehicle.
[0010] To avoid damage to the vehicle itself due to the uncertainty of the lifting device test results during the actual vehicle loading test, and since the test bench cannot be directly connected to the lifting device for testing, a fixture tooling is designed for the test process to ensure the smooth conduct of the lifting test and reduce the difficulty of the actual vehicle loading test and the risk of damage to the vehicle body.

[0012] 1. The tooling reduces the complexity of the lifting test;
[0013] 2. Reduced the impact of test result uncertainty on the vehicle body;
[0014] 3. The simplified tooling design improved the reliability of the test results and reduced the test cost.
[0015] The upper top plate and the lower bottom plate are supported by support rods. The support rods are connected to the upper top plate and the lower bottom plate by welding and are fixed by stiffening plates. The bottom of the lower bottom plate is welded with pads, which include horizontal pads and vertical pads.
[0016] Furthermore, the overall height of the clamp should not exceed 800mm.
[0017] Furthermore, the support rod consists of four channel steels welded between the upper top plate and the lower bottom plate. The welding positions between the support rod and the upper top and lower bottom plates are reinforced by secondary welding of five stiffening plates.
[0018] Furthermore, the bottom plate has dimensions of 20×720×800mm and a thickness of 20mm, the top plate has dimensions of 30×570×600mm, the pad plate has dimensions of 8×680×50mm, and the support rod has a length of 750mm.
[0019] Furthermore, the top plate has two openings with diameters of φ150mm and φ82mm, and 16 screw holes are evenly distributed around the larger opening for fastening the clamping body to the rotary reducer.
[0020] Furthermore, eight through holes are evenly distributed around the small cavity for fastening the clamp body to the rotary reducer.
[0021] Furthermore, the distance from the center of the small and large empty spaces to the right side of the top plate is 200mm, and the distance from the top edge is 285mm;
[0022] Furthermore, the spacing between the support rods in the same plane is 450mm.
[0023] Furthermore, the distance between the stiffening plate and the outer edge of the support rod is 10mm, and the opening of the support rod channel steel faces inward.
[0024] Furthermore, the pressure plate is pressed onto the lower base plate and the test frame of the lifting device and connected by bolts; bolts and nuts are used to connect the lower base plate and the test frame of the lifting device, and the slewing support of the lifting device is connected to the upper top plate by bolts.
[0025] The technical effects of this utility model are:
[0026] Using a test platform for lifting and hoisting tests offers higher safety and facilitates comprehensive observation and recording of test results, providing significant advantages over vehicle-mounted tests. By installing the 1:1 adapted lifting device with the clamping body mentioned in this article on the test platform, the test process can be successfully completed.
[0027] 1. By designing this clamping device, the complexity of the lifting test is reduced.
[0028] 2. It reduces the impact of the uncertainty of test results on the vehicle body.
[0029] 3. The simplified tooling design improved the reliability of the test results and reduced the test cost. Attached Figure Description
