Problems solved by technology
[0002] At present, the hydraulic synchronous control circuit of the tundish tank car of the steelmaking equipment is composed of a synchronous mechanism and a synchronous control unit. There is also a cumulative error in the tank, which is difficult to eliminate unless it is forced to "return to zero". In addition, the hydraulic components of the synchronous control unit will leak during the long-term steel pouring process. The problem of skewing during the process and seriously affecting the normal pouring of the continuous casting machine

Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] refer to figure 1 , a hydraulic dynamic synchronous control and position compensation system, including a detection unit, an electrical control unit and a hydraulic control unit,
[0019] The detection unit consists of the first displacement sensor 3-1 on the first lifting cylinder 1, the second displacement sensor 3-2 on the second lifting cylinder 2, the third displacement sensor 3-3 on the third lifting cylinder 3 and the first The fourth displacement sensor 3-4 on the four lifting oil cylinders 4 is formed,
[0020] The hydraulic control unit includes a speed regulating valve 1-1. The pressure oil circuit P communicates with the speed regulating valve 1-1 and the main circuit solenoid valve 2-1 through the pipeline, and the main circuit solenoid valve 2-1 passes through the oil circuit in the valve block. The channel communicates with the first branch so...

The invention relates to a hydraulic dynamic synchronization control and position compensation system which comprises a detection unit, an electrical control unit and a hydraulic control unit, wherein the detection unit is composed of four displacement sensors positioned on four lifting oil cylinders; the hydraulic control unit is composed of a speed regulating valve, a general-way electromagnetic valve and four shunt electromagnetic valves; the four shunt electromagnetic valves are respectively communicated with a rodless cavity of each lifting oil cylinder through a check valve; a rod cavity of each lifting oil cylinder is connected to an oil return pipeline through a pipeline; the displacement sensors are connected with the electrical control unit through electric cables; and the electrical control unit is respectively connected with the general-way electromagnetic valve and each shunt electromagnetic valve. During the ascending and descending processes of a tundish car, the displacement sensors and the electromagnetic valves constitute a dynamic closed-loop control system, the real-time position of the oil cylinders is dynamically maintained within an allowed error range, the synchronization control and position compensation functions of the tundish car in a long-time loading state as well as static and dynamic states can be realized, and the system has the advantages of low cost, low fault rate and low maintaining expense.
Description
technical field [0001] The invention relates to the technical field of hydraulic synchronous control of tundish cars of steelmaking equipment, in particular to a hydraulic dynamic synchronous control and position compensation system. Background technique [0002] At present, the hydraulic synchronous control circuit of the tundish tank car of the steelmaking equipment is composed of a synchronous mechanism and a synchronous control unit. There is also a cumulative error in the tank, which is difficult to eliminate unless it is forced to "return to zero". In addition, the hydraulic components of the synchronous control unit will leak during the long-term steel pouring process. In the process, there is a problem of skewing and seriously affecting the normal pouring of the continuous casting machine. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a hydraulic dynamic ...
