Description
Technical Field
[0001] The utility model relates to a device for measuring the vertical spacing of a rotating oil cylinder, belonging to the technical field of oil cylinder measurement. Background Art
[0002] The front suspension of large mining vehicles generally uses a gas suspension cylinder. However, the cylinder rod of the gas suspension cylinder of some models is integrated with the front wheel, which causes the cylinder rod and the cylinder barrel to rotate when the front wheel rotates. At the same time, when the vehicle is running, the cylinder barrel and the cylinder rod will also move up and down. Therefore, it is very difficult to accurately measure the vertical movement distance between the cylinder barrel and the cylinder rod.
[0003] The commonly used test method now is to use a wire-type displacement sensor for measurement, which is to fix the pull head at the lower part of the cylinder rod and the displacement sensor at the lower part of the cylinder barrel. This measurement method cannot overcome the measurement error of the vertical spacing caused by the rotation between the cylinder rod and the cylinder barrel. In order to solve the error caused by the above measurement method, a slide rail structure is designed to fix the pull head on a slide rail. This can indeed reduce the error caused by the rotation of the cylinder, but there is still a certain error, because the soft steel wire rope cannot drive the pull head in the slide rail back to the initial position in time, resulting in fluctuations in the output vertical spacing value. Summary of the invention
[0004] In order to solve the vertical spacing measurement error caused by the oil cylinder rotation and the pull head failing to return to the initial position in time, the utility model designs a rotating oil cylinder vertical spacing measurement device based on the MTS displacement sensor, and optimizes the slide rail to a cross-slide rail structure.

[0035] Further solutions: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the mounting plate is provided with a plurality of through holes, and at least one cable tie is wound around the oil cylinder rod 5 at least once, and then passed through the through hole on the mounting plate again to be fastened, so as to fix the cross rail on the oil cylinder rod 5.
