The clamping of the spring clamp is the spring, which is carried out by the spring seat, connecting rod, pliers and tongs

The rail is clamped tightly. The circuit of the clamping device is interlocked with the main engine walking circuit, namely, when the clamp of the clamp is completely opened, the cart walks

The circuit can be connected.

The clamping device's legs are open to the hydraulic system of its own, and its way of working is: control the circuit by clamping device, in the main

Before walking, the machine can only connect the oil pump motor and the power supply of the solenoid valve. When the tongs are fully opened,

The motor power of the oil pump is cut off by the limit switch, (but the solenoid valve is still in full power at this time), while the main engine walks the interlocking circuit

Connect, the host can start to walk. When the oil pump motor is out of power, the hydraulic system is due to the pressure of the one-way valve and the solenoid valve

Ensure that the tongs are open.

If the rail is clamped, the solenoid valve should be cut off and the pressure oil will flow back to the tank. When the pressure oil comes back,

The throttle action of the throttle valve on the integrated block is to adjust the conch next to the pressure gauge interface on the integrated block

Nail, can make the closing time of tong leg adjust freely.

When the electromagnetic valve is cut off, the interlocking circuit also interrupts the motor power of the main engine. So, it's appropriate

When adjusting the adjustment screw next to the interface of the integrated pressure gauge in the hydraulic station, adjust the timing of clamping process of the clip rail to ensure

The main engine can stop before the clamping leg is in contact with the rail. This is important because the clamping device will not be able to walk on the host

Clamp down, otherwise, it will cause damage to the rail and rail.

As the hydraulic system is leaking and the legs are opened, after a period of time, the opening will be reduced, when reduced to

To some extent, the limit switch will cut off the time relay and connect the motor power of the oil pump. The pump motor is electrified

Quickly fill the cylinder with oil, and the tongs return to full open position. At this time limit switch can cut off the oil pump motor power supply and

Connect time relay power. In the process, the delay action of the time relay will enable the large car to move through the interlocking relay K5

Always have power, so it won't affect the normal walking of the cart.
