Abstract

The invention provides a counter weight testing device of an abnormal environment of an oil hydraulic cylinder. The counter weight testing device is characterized by comprising a rack, a counter weight body, and a counter weight body connection structure and an oil hydraulic cylinder connection structure which are arranged between the rack and the counter weight body, wherein the rack is further provided with a hand pressing device; the hand pressing device is connected with the oil hydraulic cylinder; the oil hydraulic cylinder is arranged on a hydraulic cylinder connection seat structure; the hand pressing device is connected with the oil hydraulic cylinder through a gas pressure pipe. The counter weight testing device of the abnormal environment of the oil hydraulic cylinder, provided by the invention, has the beneficial effects of simple structure, convenience for utilization and accuracy in testing direction linkage; testing data is accurate, and the device is suitable for testing oil hydraulic cylinders with various types.

Description

technical field [0001] The invention relates to a counterweight test device for an oil pressure cylinder in an abnormal environment. Background technique [0002] At present, the hydraulic cylinders suitable for the cabs of heavy trucks have to go through tests and counterweight experiments to determine the suitable weight and pressure of the hydraulic cylinders after the production is completed to ensure the suitability of the hydraulic cylinders. The existing counterweight connection structure arranged between the counterweight and the bracket has problems such as inflexible use and inaccurate multi-directional test data, which directly affects the test data and use safety of the hydraulic cylinder. [0003] And the existing hydraulic cylinder test method is only to test the hydraulic cylinder with a counterweight in the vertical direction. In this way, not only the test data is inaccurate, especially the data obtained in the abnormal environment of the test is inaccurate...
