As shown in Figure 7, the specific working principle is: when the rotary disk 1 needs to be rotated, the front button of the foot switch 11 sends a signal to the corresponding relay inside the electric control cabinet, wherein the armature inside the relay is energized and pulled in, the control The DC motor works, and at the same time, the left coil of the three-position four-way solenoid valve that controls the rotation (ie, the left rotary solenoid valve) is energized, and the coil is energized to push the internal valve core of the reversing valve to reverse to the right, so that the pressure oil flows to the side of the hydraulic motor 204 The pressure port drives the hydraulic motor 204 to rotate, the hydraulic motor 204 drives the worm 205 to rotate, the worm 205 drives the outer ring to rotate, and then realizes the clockwise rotation of the rotary disc 1; as shown in Figure 4, the worm rotates inward, driving the outer ring clockwise Rotate, the worm rotates outward, driving the outer ring to rotate counterclockwise.

The button on the rear side of the foot switch 15 sends a signal to the corresponding relay inside the electric control cabinet. After the armature inside the relay is energized and closed, the DC motor is controlled to work, and at the same time, the right coil of the three-position four-way solenoid valve that controls the rotation (that is, the right coil) Rotary solenoid valve) is energized, the coil is energized to push the internal valve core of the reversing valve to change direction to the left, so that the pressure oil flows to the pressure port on the other side of the rotary motor, and drives the rotation of the hydraulic motor. The hydraulic motor 204 drives the worm 205 to rotate, and the worm 205 drives The outer ring rotates to realize the counterclockwise rotation of the rotary disk 1 .

When the rotary disc 1 needs to be raised and lowered, the hand-held remote control 10 extends the button to send a signal to the corresponding relay inside the electric control cabinet. After the armature inside the relay is energized and closed, the DC motor is controlled to work, and at the same time the lifting solenoid valve that controls the lifting is activated. The coil on the right side is energized, and the coil is energized to push the internal valve core of the reversing valve to change direction to the left, so that the pressure oil flows to the rodless cavity of the hydraulic cylinder 6, and pushes the hydraulic cylinder 6 to extend; the retract button 10 of the hand-held remote control sends a signal to the electric The corresponding relay inside the control cabinet, after the internal armature of the relay is energized and closed, controls the DC motor to work, and at the same time energizes the left coil of the lifting solenoid valve that controls the lifting, and the coil is energized to push the inner spool of the reversing valve to the right, so that The pressure oil flows to the rod chamber of the hydraulic cylinder 6 to push the hydraulic cylinder 6 to retract, thereby realizing the lifting function of the rotary disc 1 .

It should be noted that "+" in Fig. 7 means power on, and "0" means power off.

In order to clearly express the direction of the oil circuit, the following is an example of platform lifting: during the platform lifting process, the oil pump sucks oil from the oil tank, and then discharges the pressure oil through the hydraulic hose to the P port on the valve block of the solenoid valve group, and the P port passes through The internal channel communicates with the P port of the one-way hydraulic lock and the P port of the solenoid valve. The P port of the solenoid valve communicates with the A port of the solenoid valve through the reversing spool to the left, and the A port of the solenoid valve passes through the A port of the one-way hydraulic lock. One-way valve (push open the one-way valve), the inner hole of the valve block returns to the A port on the valve block, and then the A port passes through the hydraulic hose to the rodless chamber of the hydraulic cylinder, pushing the cylinder rod out and compressing the rod chamber at the same time. The hydraulic oil in the rod cavity is discharged and returned to the B port on the valve block through the hydraulic hose. The B port communicates with the B port of the one-way hydraulic lock and the B port of the solenoid valve through the inner hole of the valve block. The spool is switched to the left to communicate with the T port of the solenoid valve, and then the hydraulic oil passes through the T port of the one-way hydraulic lock, the inner hole of the valve block, and then returns to the T port on the valve block, and the T port returns to the hydraulic pressure through the hydraulic hose. inside the fuel tank.

When the platform is lowered, the oil pump absorbs oil from the oil tank and then discharges the pressure oil through the hydraulic hose to the P port on the valve block of the solenoid valve. The P port communicates with the P port of the one-way hydraulic lock and the P port of the solenoid valve through the internal channel. The P port of the solenoid valve communicates with the B port of the solenoid valve through the reversing spool to the right. valve to make it open to return oil), the inner hole of the valve block returns to the B port on the valve block, and then the B port passes through the hydraulic hose to the rod chamber of the hydraulic cylinder, pushing the cylinder rod to retract and compressing the rodless chamber at the same time, so that the rodless The hydraulic oil in the cavity is discharged, and returns to the A port on the valve block through the hydraulic hose, and the A port communicates with the one-way hydraulic lock A port check valve (the one-way valve has been opened) and the A port of the solenoid valve through the inner hole of the valve block. The A port of the solenoid valve is switched to the right through the reversing spool to communicate with the T port of the solenoid valve and the T port of the one-way hydraulic lock. The hose goes back into the hydraulic tank. The rest of the actions are based on this principle, so I won't introduce them one by one here.
