specific Embodiment

[0033] The main oil return pipeline C communicates with the first pipeline A1 through the manual reversing valve 21, and the main oil supply pipeline D communicates with the second pipeline B1 through the manual reversing valve 21. The two sets of pipelines can both output Oil can also be input into oil. The hydraulic control system of the roll dismantling manipulator controls the lifting action of the jacking hydraulic cylinder by the manual reversing valve 21 and four one-way speed regulating valves. The one-way speed regulating valve itself is a kind of pressure and temperature compensation. Type valve, which can maintain a stable flow, does not change with system pressure and temperature, and saves time and effort for adjustment. Using it to control the flow in the hydraulic circuit can precisely control the lifting speed of the jacking hydraulic cylinder, thus ensuring the synchronization between different hydraulic cylinders. The combined check valve can make the liquid f...

Abstract

The invention provides a hydraulic control system of a roller dismounting manipulator. The hydraulic control system comprises a first jacking hydraulic cylinder and a second jacking hydraulic cylinder, wherein the two hydraulic cylinders share a group of hydraulic control pipelines, and the hydraulic control pipelines comprise a first control assembly, a second control assembly, a third control assembly and a fourth control assembly; and the fourth control assembly comprises four one-way speed regulating valves, the first one-way speed regulating valve and the second one-way speed regulating valve are located on the second pipeline, the third one-way speed regulating valve and the fourth one-way speed regulating valve are located on the first pipeline, and the four one-way speed regulatingvalves control the oil passing amount in the hydraulic pipelines, so that the lifting speed of the jacking hydraulic cylinders and the synchronism between the jacking hydraulic cylinders are controlled. According to the hydraulic control system, a manual reversing valve is combined with the one-way speed regulating valves to control the system loop flow, then the lifting speed of a single jackingcylinder is controlled, finally the actions of the four jacking hydraulic cylinders are adjusted to be consistent, and meanwhile, rod cavities of the hydraulic cylinders are connected with hydrauliccontrol one-way valves to prevent the phenomenon of natural downward sliding of the hydraulic cylinders.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control, in particular to a hydraulic control system of a roll removing manipulator. Background technique [0002] In the rolling process of hot-rolled section steel, the roll removal manipulator is an indispensable auxiliary device. It is composed of a platform that can move back and forth and two liftable brackets, and is powered by a hydraulic system to work. The roll dismantling manipulator device is located under the steel rolling production line. Its task is to disassemble the rolled rolls from the steel rolling production line as a whole, take the roll body to the machine tool for processing, and then assemble the processed roll body and bearing housing for the next step. Prepare for a roll change. The two brackets of the roller removal manipulator device are respectively controlled by four jacking cylinders at the same time. If the movements of these four jacking cylinders cannot be sy...
