Hydraulic cylinder device and hydraulic cylinder behavior control system with same

Abstract

The utility model relates to a hydraulic cylinder device and a hydraulic cylinder behavior control system with same. The hydraulic cylinder device comprises a cylinder body, a piston and a piston rod, wherein the piston moves in the cylinder body, one end of the piston rod is connected with the piston, and the other end thereof extends out of the cylinder body; and a plurality of signal through holes which are longitudinally arranged along the cylinder body to divide a piston stroke into a plurality of stroke sections are formed on the wall of the cylinder body. The hydraulic cylinder device also comprises a plurality of pressure sensors arranged corresponding to the signal through holes. Compared with the prior art, the invention can conveniently meet the real-time monitoring of the preset section position of the total stroke of the piston, and has the advantages of low cost, good generality and strong anti-interference capacity, and is favorable for giving full play to the powerful data-processing operation capacity of an intelligent controller, and the like.

Description

technical field [0001] The invention relates to a hydraulic cylinder device and a hydraulic cylinder behavior control system with the hydraulic cylinder device, especially related to the real-time collection of pressure data in the cylinder body through a plurality of pressure sensors and the real-time calculation and monitoring of the movement position of the oil cylinder by a controller, and can A hydraulic cylinder that controls the motion behavior of the cylinder in several sections of the full stroke. Background technique [0002] Generally speaking, in mechanical equipment such as concrete pumping, the effect of the motion behavior control of the main cylinder directly determines its external work and various performances of its own operation. [0003] In the current related industries, the control of the movement behavior of the main cylinder is limited to the reversing of its action. The main methods are: electric reversing controlled by proximity switch or travel sw...

AI Technical Summary

Problems solved by technology

Its disadvantages: there are requirements for the flow of hydraulic oil and it cannot be interfaced with the electronic control system

Its disadvantage: there is still a large pipeline liquid capacity (at least one oil pipe must lead the oil to the differential pressure switch) which affects the frequency response capability

[0007] All the above-mentioned control methods are only speed reversing control, and there is no real-time detection of the operating position of the piston of the main cylinder, and then control the speed and acceleration of the piston of the main cylinder in each stroke setting segment. It is not conducive to giving full play to the powerful data processing and computing capabilities and coordinated control capabilities of today's intelligent controllers
