The invention provides a radial deflection sensor of a cylinder barrel so as to solve the problem that the cylinder barrel cannot be subjected to online, real-time and accurate measurement by using the conventional measurement tool, and relates to the technical field of detection of a working state of a hydraulic cylinder. The radial deflection sensor of the cylinder barrel comprises the cylinder barrel, and is characterized in that a radial deflection sensor bar is encircled on the outer wall of the cylinder barrel; one end of the radial deflection sensor bar is a free end, and the other end of the radial deflection sensor bar is a fixed end; the free end of the radial deflection sensor bar is connected with a measurement instrument; and the fixed end of the radial deflection sensor bar is fixedly connected to the outer wall of the cylinder barrel. According to the radial deflection sensor of the cylinder barrel, the change of the circumference of the cylinder barrel is measured through the radial deflection sensor bar encircled on the outer wall of the cylinder barrel, so that the problems that the conventional length measurement tool is inconvenient to fix and mount and cannot finish automatic measurement are solved; and the barrel diameter change of the cylinder barrel is measured by measuring the circumference change of the cylinder barrel, the measurement value is amplified by pi times, the radial deflection sensor bar is encircled for n turns, and the measurement value is amplified by n*pi times, so that the measurement precision is high.
Description
Technical field: [0001] The invention relates to the technical field of pressure cylinder working state detection, in particular to a cylinder radial deformation sensor. Background technique: [0002] Many construction machinery and equipment, such as excavators, cranes, loaders, etc., including other special vehicles such as fire trucks, the various movements of their working devices are mainly driven by hydraulic transmission, and a large number of them use cylinder mechanisms. In the system of cylinder actuators, hydraulic failures are usually reflected by actuators such as hydraulic cylinders. When using these equipment, it is often found that the oil cylinder does not work properly, the oil cylinder is underspeeded, crawling and other faults occur, the cylinder barrel is deformed or the oil rod is bent, and even the cylinder explodes, and the equipment is unstable and collapsed, which leads to serious consequences such as major accidents. The reasons are mostly due to ...
