Abstract

The invention discloses a rotary limiting device and a using method thereof. The rotary limiting device comprises a rotary limiting rotating disc and a piston cylinder. The rotary limiting rotating disc is of a disc structure and is coaxially and fixedly connected with a rotary shaft, and a plurality of limiting holes are evenly formed in the outer circumference of the rotary limiting rotating disc; and the piston cylinder is matched with limiting holes in an inserted mode through a telescopic piston rod arranged in the piston cylinder, a sealing plate divides the piston cylinder into an oil cavity and a spring cavity, the oil cavity communicates with a pressure oil source through a three-position three-way valve arranged on the side part of the oil cavity, a spring is arranged in the spring cavity, the top end of the spring is matched with the sealing plate in a pressing mode, and the bottom end of the spring is matched with the piston cylinder in a pressing mode. According to the rotary limiting device, the piston rod can be driven through the elastic force of the spring to limit the limiting holes, the system does not need to do work continuously, and the economical efficiency and the environmental protection property are effectively improved; and the limiting device can be controlled to work through the valve position of the three-position three-way valve, and the control system is simple and reliable in structure.

Description

technical field [0001] The invention relates to a rotation limiting device, in particular to a rotation limiting device and a usage method thereof, and is particularly applicable to a hydraulically driven rotation limiting device. Background technique [0002] The rotating machinery in the position servo control mechanism needs to stop precisely at a fixed position without being affected by the load and external factors after reaching the target position. The existing rotating machinery usually cannot maintain a certain position after losing power, and is prone to rotation due to the influence of load and external factors cause a change in position. At present, the limit of the rotating machinery in the position servo control mechanism is usually carried out in three ways: continuous power supply of the rotating machinery, mechanical brake or electromagnetic brake; [0003] The mechanical brake currently used includes a brake arm, a brake body, a brake wheel and a push rod,...
