The opening and closing machine is used for all kinds of large-scale water supply and drainage, water conservancy and hydropower projects. It is used to control the lifting and lifting of various large, medium-sized cast iron gates and steel gates to open and close.

By type:

The hydraulic lifting and closing machine, the lifting and closing machine, the door machine, the handwheel and the closing machine, the handshaking and closing machine, the screw type opening and closing machine, etc.

1. The opening and closing machine includes motor, hoist, frame, protective cover, etc. Adopt the three - level deceleration mode, with the state - paid drive, the output is larger. The supporting steel frame of the opening and closing machine shall overcome the unevenness of the soil to reduce the noise and vibration of the whole machine.

The safety operating procedures of the opening and closing machine are as follows:

1. The construction unit shall install the lifting and closing machine on a flat, solid foundation with good vision, and the fuselage and anchor must be firm. The center line of the opening and closing machine and the guide pulley should be perpendicular to the positive, and the distance pulley should be no less than 15 meters.

2. Before adjusting the operation, check the wire rope, clutch, brake, insurance ratchet, driving pulley, etc., to ensure safe and reliable operation. The wire rope must be arranged neatly on the drum, and the minimum number of assignments should be kept at least three times. During homework, no one is allowed to cross the wire rope of the open and closing machine to prevent accidents.

3. When carrying heavy objects to stay in the air, except using the brake, use a ratchet safe. When operating, do not leave the post without permission.

4. To follow the signal of the conductor at work, when the signal is unknown or may cause an accident, the operation should be suspended, and the operation can be continued after being made clear. A power failure in the operation should open the knife immediately and place the items down.

Load test method:

1. The operating personnel of the hoist must have the structure, performance and operation method of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine.

Before operation, inspect the machine thoroughly, the lubrication condition is good, and the bolt is loose.

3. When the opening and closing machine is operating, the operator shall not leave the scene and find the problem to stop immediately.

4. When servicing the machine, the load must be removed.

5. When used, oil should be injected with oil hole at any time. Always maintain sufficient lubricating oil. The screw should be used regularly to remove the oil and grease to prevent rust.
