Hydraulic control system

Abstract

A hydraulic control system comprises an oil tank, an oil pump, a filter, an overflow valve, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a one-way valve, a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder. The oil tank, the filter, the oil pump and the one-way valve are sequentiallyconnected to form an oil delivery way. A first oil way and a second oil way are arranged at the downstream position of the one-way valve, the first electromagnetic valve is arranged on the first oilway, the second electromagnetic valve is arranged on the second oil way, the first oil way is connected with one ends of the first hydraulic cylinder, the second hydraulic cylinder and the third hydraulic cylinder, and the second oil way is connected to the other ends of the first hydraulic cylinder, the second hydraulic cylinder and the third hydraulic cylinder. The first oil way is connected with a first oil return way, and the second oil way is connected with a second oil return way.

Description

technical field [0001] The invention relates to the application field of a flexible mechanism in a hydraulic system, in particular to a hydraulic control system. Background technique [0002] Poisson's ratio is a basic parameter of structural deformation. Poisson's ratio in ordinary materials is generally a positive number, and the range is mostly between 0-0.5. When ordinary materials are stretched in one direction, their cross-section will shrink with stretching, but the cross-section of negative Poisson's ratio materials (auxetic materials) will expand with stretching, such as single crystal sulfide ore, Polytetrafluoroethylene (PTFE) and silica with tetrahedra. [0003] Inspired by the above-mentioned physical properties of negative Poisson’s ratio materials, researchers at home and abroad have designed many different negative Poisson’s ratio structures. When the negative Poisson's ratio structure is under pressure in the axial direction, it will shrink in the axial an...

AI Technical Summary

Problems solved by technology

[0005] 1. In the flexible mechanism of the prior art, the cells are all connections between complete individuals, but the functional differentiation between cells of different shapes is not considered, and if different cells are connected, the connection between different structural forms Difficulty connecting

[0006] 2. The connection between the cells in the prior art is just a connection, but the connection is not refined, and the connection stiffness and support cannot be guaranteed.

[0007] 3. The ribs in the prior art only serve to increase the strength, but do not consider the direction of force and the bending resistance at all.

[0008] 4. When the flexible mechanism in the prior art is applied, it must be connected to the device with the help of a connecting mechanism, and the adaptability and detachability are not considered.

[0009] 5. The flexible structure of the hydraulic cylinder in the prior art is often just a cushion. If it is thin, it will be easily damaged and the effect will not be good. If it is thick, it will lose space utilization.

[0010] 6. When the flexible mechanism in the prior art is directly used for buffering, there is no additional guiding mechanism, and unexpected deformation of the flexible mechanism in the direction of the offset force is prone to occur

[0011] 7. The cells of the flexible mechanism in the prior art only use the bending deformation to provide the buffer force, and this buffer is only provided by the deformation force in the linear direction, and the effect is only provided by a single force

[0012] 8. Most of the cells of the flexible mechanism in the prior art are composed of several identical cells through linear superposition, so it is difficult to achieve greater buffer support
