Abstract

The invention provides a pneumatic balance system for a cylinder. The system comprises a cylinder with a piston rod vertically downwards arranged, and a brake arranged corresponding to the piston rod of the cylinder. The system further comprises a first gas supply pipeline communicating with a rod cavity of the cylinder, and a second gas supply pipeline communicating with the brake; the first gas supply pipeline is provided with a pressure reducing valve and an exhaust valve, wherein the exhaust valve is arranged between the pressure reducing valve and the cylinder; and the second gas supply pipeline is provided with a normally-closed two-position three-way valve. In the pneumatic balance system for the cylinder, through control of the system, when a detecting platform works, the pressure of the rod cavity in the cylinder is balanced to always counteract self gravity of the detecting platform. If such special conditions as gas breakage and power failure suddenly occur, the brake can quickly lock a cylinder rod, so that a ball screw cannot be damaged in working of the detecting platform, the lifting precision control of the detecting platform is improved, and the accuracy of detecting results is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic detection of steel pipes, and in particular relates to a pneumatic balancing system for a cylinder. Background technique [0002] At present, the production process of steel pipes at home and abroad involves the application of pneumatic principles. However, due to the high gravity of the detection platform itself, the ball screw will be severely worn and the service life of the screw will be reduced. Therefore, how to design a balance system for the detection platform has become a new research and development topic. Contents of the invention [0003] In view of this, the present invention aims to propose a pneumatic balancing system for the cylinder to control the detection platform, thereby reducing the wear of the ball screw. [0004] In order to achieve the above object, the technical solution created by the present invention is achieved in this way: [0005] A pneumatic balancing system...
