[0002] The vacuum oil injection system needs to be tested after production. The testing equipment of the vacuum oil injection system is usually equipped with multiple hydraulic cylinders and multiple hydraulic motors. Among them, the multiple hydraulic cylinders and multiple hydraulic motors on the testing equipment need to be connected to an external hydraulic station. The hydraulic station can control the flow and pressure of the liquid through the valve assembly, and drive the multiple hydraulic cylinders and multiple hydraulic motors to realize various mechanical movements.

Although some hydraulic stations are equipped with vibration detection structures, there is no guarantee that vibration detection will be performed after each startup, resulting in the failure to promptly detect vibration in the hydraulic station, which can easily cause subsequent major system failures due to vibration problems; 2. There is usually a lack of protective structures, which makes it easy for workers to accidentally touch the hydraulic station after debugging, reducing the hydraulic accuracy.

When the hydraulic unit starts to vibrate less, the vibration detection slider does not move or slides slightly to the left or right under the elastic force of the four coil springs A.

[0019] In addition, when the vibration detection slider can slide to the left under the action of vibration, the limit baffle on the left can press the switch on the left; when the vibration detection slider can slide to the right under the action of vibration, the limit baffle on the right can press the switch on the right. When one or both of the alarms are working, it means that the hydraulic unit vibrates greatly after startup; at this time, the staff turns off the hydraulic unit, then checks the cause of the vibration, and restarts it after troubleshooting to avoid failure of the hydraulic unit due to vibration; when the two alarms do not work, it means that the hydraulic unit vibrates less after startup; at this time, the hydraulic unit can work normally.

[0020] 2. In the present invention, when the staff pulls the U-shaped handle upward, the rectangular blocking frame and the rectangular movable block move upward at the same time; at this time, the bottom ends of the two hollow stabilizing tubes are separated from the two stabilizing circular holes; when the staff continues to pull the U-shaped handle upward, the rectangular blocking frame stops moving, and the U-shaped handle drives the rectangular movable block to continue to move upward, so that a row of control buttons moves to the outside of the rectangular blocking frame, ensuring that the bottom ends of the two hollow stabilizing tubes are always in a separated state from the two stabilizing circular holes before the hydraulic unit is started, and realizing automatic vibration detection after each start of the hydraulic unit;

[0021] In addition, when the hydraulic unit is started, the staff resets the U-shaped handle, and the two hollow stabilizing tubes can be inserted into the two stabilizing circular holes under the action of gravity, ensuring that the vibration detection slider is in a fixed state when the hydraulic unit is working, thus ensuring the stability of the hydraulic unit when working;

[0022] In addition, when the hydraulic unit needs to be inspected or parts replaced, the staff continues to pull the U-shaped handle upwards with force to make the anti-accidental touch frame pass through the eight solid blocking balls. When the four strong magnetic rings A come into contact with the four strong magnetic rings B, the four strong magnetic rings A and the four strong magnetic rings B can be adsorbed together, and the adsorption force of the four strong magnetic rings A and the four strong magnetic rings B is greater than the gravity of the anti-accidental touch unit and the control unit, which is convenient for the staff to inspect or replace parts of the hydraulic unit. The setting of the anti-accidental touch net protects the hydraulic unit, avoids accidental touch after the hydraulic unit is debugged, and improves the hydraulic accuracy of the hydraulic unit.
