Embodiment Construction

[0019] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0020] The present invention relates to a control device for dual oil supply systems simultaneously supplying dual oil cylinders to work synchronously, such as Figure 1-2 As shown, it is a device body, in which two parallel pipes 1 and straight pipes 2 are formed. "Shape structure. The two ends of the two parallel pipelines 1 are respectively an oil inlet 11 and an oil outlet 12, and the two oil inlets 11 respectively extend to the surface of the device body, so as to be adapted and connected to the external double oil supply system respectively, and the second oil outlet The ports 12 are formed in the device body, and communicate with the pipe bodies of the direct connection pipes 2 respectively. The two ends of the straight-connecting pipeline 2 are two oil supply ports 21, which also respectively extend t...

Abstract

The invention discloses a control device used for simultaneous and synchronous work of double oil cylinders of a double-oil-supply system. The control device comprises a device body, wherein two parallel pipelines and a directly-connected pipeline are formed in the device body; two ends of each of the two parallel pipelines are respectively configured to be an oil inlet and an oil inlet; the oil inlets are respectively communicated with a pipe body of the directly-connected pipeline, two ends of the directly-connected pipeline are configured to be two oil supply ports; an adjusting pipeline vertically communicated with the directly-connected pipeline is also formed on the device body, corresponding to the middle position of the two parallel pipelines; an adjusting bolt capable of extending in the directly-connected pipeline and adjusting the flow of the oil in the directly-connected pipeline is assembled in the adjusting pipeline in a matching mode; by adopting the inching control for the extending amount of the adjusting bolt in the directly-connected pipeline, the hydraulic oil in the directly-connected pipeline realizes self-balancing adjustment under inching control with the aid of the fluid characteristic of the hydraulic oil, the damping of the parallel pipelines is greater than that of the directly-connected pipeline, but is lower than a backpressure caused by an unbalanced external load, so that the two systems are enabled to work simultaneously and run synchronously, the high-precision synchronous work of the double oil cylinders is truly realized.

Description

technical field [0001] The invention relates to the field of control devices for oil supply systems, in particular to a control device for dual oil supply systems that simultaneously supply and work synchronously with two oil cylinders. Background technique [0002] At present, hydraulic technology is required in many fields, and some of the hydraulic systems need to use dual oil supply systems and parallel double cylinders to work together. Due to the differences in the system itself and the difference in the load of the two cylinders, it is difficult to do cylinder activities. to more precise synchronization work. At present, there are many methods to solve the problem of oil cylinder synchronization, such as the use of electrical limit method, shunt method, detection and comparison method, etc., all of which have problems such as complex structure and high cost. Irregular, chaotic and complex characteristics, the traditional method adopts complex structure to control and...
