[0003] At present, the test of the maximum load of the crane is to use the method of manually increasing the load on the crane. Generally, the crane can carry more than 16 tons, which requires manual continuous increase of the load until the load reaches 16 tons. This method of operation It is troublesome, it consumes a lot of manpower, and it cannot be measured continuously; secondly, when the load reaches the maximum load critical value that the crane can bear, it is easy to increase the load overload, so the measured maximum load that the crane can bear is not accurate, so it takes a A test device that can be loaded by its own movement, can measure continuously, and has high precision

The invention provides a test device for testing the vehicle lifting jack performance. A loading oil cylinder comprises an oil cylinder sleeve and an oil cylinder pole. The oil cylinder sleeve is vertically fixed on a crossbeam. The oil cylinder pole is arranged in the oil cylinder sleeve. The oil cylinder pole can upwardly and downwardly stretch out and draw back in a vertical direction along the oil cylinder sleeve. One end, which faces a baseplate, of the oil cylinder pole is provided with a loading head. The loading head comprises an oil cylinder ball head, an oil cylinder ball head sleeve and an oil cylinder flange. The oil cylinder ball head is arranged on the tail end of one end, which faces the baseplate, of the oil cylinder pole. The oil cylinder ball head has a structure greater than 1 / 2 hemisphere and less than a sphere. The oil cylinder ball head is externally provided with the oil cylinder ball head sleeve. The internal hole shape of the oil cylinder ball head sleeve is matched with the curved shape of the oil cylinder ball head. The oil cylinder ball head sleeve can slide along the oil cylinder ball head. The lower side of the oil cylinder ball head sleeve is fixedly provided with the oil cylinder flange. According to the test device for testing the vehicle lifting jack performance, the structure is simple, operation is easy and convenient, loading can be performed through its own motion, the accuracy is high and the loading head is replaceable.
Description
technical field [0001] The invention relates to a test device, in particular to a test device for testing the performance of a car frame. Background technique [0002] The car crane is suitable for the lifting and lowering operation requirements of railway electric locomotives, diesel locomotives and other vehicles, and is convenient for the maintenance of car bodies, bogies and other components. Generally, a group of four works at the same time. In order to avoid the overturning of the lifted railway locomotive caused by exceeding the load of the crane during the lifting and lowering operation of the railway electric locomotive, causing safety accidents. Therefore, before the crane is put into production and use, it is necessary to test the maximum load and other properties of the crane to ensure the reliability and safety of the crane. [0003] At present, the test of the maximum load of the crane is to use the method of manually increasing the load on the crane. Generall...
