Abstract
Description
Technical Field
[0001] The utility model relates to the field of railway T-beam detection, in particular to a railway T-beam static load test frame. Background Art
[0002] After the railway T-beam is produced, it needs to undergo a static load test to ensure that it is qualified and meets the use requirements. The usual static load test is to place several cement blocks on the T-beam one by one, and then start the test and record the data. The operation process is complicated, the test process is long, and the data is inaccurate, which is not conducive to improving the test efficiency. Summary of the invention
[0003] In order to solve the above problems, the technical solution of the utility model is: a railway T-beam static load test frame, which consists of a crossbeam and columns installed at both ends of the crossbeam, a connecting plate is arranged on the column, and a plurality of hydraulic cylinders are arranged on the lower surface of the crossbeam, and a pressure sensor is arranged at the bottom of each hydraulic cylinder.
[0004] In order to enhance the strength of the cross beam, a reinforcing beam is arranged above the cross beam in parallel, and vertical beams are evenly arranged between the reinforcing beam and the cross beam.
[0005] In order to improve the strength of the cross beam, an inclined beam is provided between the reinforcing beam and the cross beam.
[0006] The beneficial effects of the utility model are:
[0007] During the experiment, the two ends of the crossbeam and the two ends of the T-beam are fixed together by long bolts. The test data can be recorded through the hydraulic cylinder and the pressure sensor. The pressure applied to the T-beam by a hydraulic cylinder can be adjusted at any time as needed. The test results are more accurate. At the same time, the test is more convenient and quick, which is conducive to improving the efficiency of the experiment.
[0008] The detection device has a simple structure, is easy to manufacture, has a low cost, has a low maintenance cost, and is easy to promote and use. At the same time, after the use of the experimental frame, it can be disassembled and shipped, which is convenient for secondary assembly and use. BRIEF DESCRIPTION OF THE DRAWINGS
