Laser measuring device for deflection of leveling oil cylinder

Abstract

The invention discloses a laser measuring device for the deflection of a leveling oil cylinder. The laser measuring device for the deflection of the leveling oil cylinder comprises an upper fixing assembly, a lifting mechanism, a reflector and a laser displacement sensor, wherein the upper fixing assembly is installed on a cylinder barrel of the leveling oil cylinder, and the lifting mechanism is installed on the upper fixing assembly and can move up and down relative to the upper fixing assembly; the reflector is installed at the end, close to the laser displacement sensor, of the lifting mechanism, and the laser displacement sensor detects the deflection of the leveling oil cylinder according to light reflected by the reflector. The laser measuring device for the deflection of the leveling oil cylinder can monitor the deflection of the leveling oil cylinder, the labor intensity of workers is relieved, and the detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of leveling devices, and in particular relates to a laser measuring device for leveling the sinking amount of an oil cylinder. Background technique [0002] In order to provide a good launch platform for the equipped vehicle, it is necessary to perform leveling operations on the vehicle body and keep it in a horizontal position. The prior art adopts hydraulic leveling oil cylinder control technology to realize vehicle body leveling. Because of its high control precision, easy design, maintenance and use, it is widely used in equipment vehicles. The sinking amount of the hydraulic leveling cylinder of the vehicle is an important indicator reflecting the static holding performance of the leveling cylinder. Before delivery, each equipped vehicle needs to check the holding performance of the hydraulic leveling cylinder to confirm that it meets the requirements of no-load or full-load holding for a certain period...

AI Technical Summary

Problems solved by technology

[0003] In the test of the sinking amount of the leveling cylinder of the equipped vehicle, the instrument used to detect the holding capacity of the leveling cylinder is mainly a steel tape or a dial indicator. The steel tape is attached to the outer cylinder of the leveling cylinder to measure the ground distance, or a dial The sub-meter is directly adsorbed on the surface of the inner cylinder of the leveling oil cylinder, and is pushed against the lower edge of the outer cylinder. Manual measurement is used to read and record the value, and the measured value is compared at a certain time interval, and the change of the sinking amount is manually calculated. This measurement method It is easily affected by multiple factors such as product working conditions, environmental factors of the test site, and personnel operations. The test accuracy is limited, and the obtained data is not conducive to effective analysis of product performance. It is difficult to ensure the accuracy of the test structure, especially during the test process. The body needs to be kept under load for 12h to 48h. The vehicle is prone to the failure of the oil cylinder, causing the risk of sinking or even overturning the vehicle body. Therefore, personnel need to be on duty for a long time, and manual tracking and recording are required for multiple comparison calculations, which is labor-intensive. Big
