Some brief introductions of hoist and gate

Hoist

The gate hoist is a device used to operate the movement of the door leaf to achieve the purpose of opening and closing the orifice. It is widely used in water conservancy and hydropower projects. Mainly divided into screw type, winch type, hydraulic and other types. Among them, screw type and winch type are widely used.

The function of the gate hoist: to operate the movement of the door leaf. Type: screw type, winch type, hydraulic type. Structure: motor, frame, hoist, protective cover, etc.! Application areas: water conservancy, hydropower engineering.

Purpose and structure

Used in various large water supply and drainage, water conservancy and hydropower projects. It is used to control the lifting of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing.

Structural features:

1. The gate hoist consists of a motor, a gate hoist, a frame, a protective cover, etc.; it adopts a three-stage speed reduction method and uses a national rotary to drive, and the output torque is larger. The steel frame of the gate hoist overcomes the unevenness of civil construction to reduce the noise and vibration of the whole machine.

2. It adopts outdoor type long-time working motor with protection grade ≥IP155. The stroke control mechanism adopts the principle of decimal counter to control the stroke error of 0.5%. Torque protection control is the principle of protecting electrical appliances by triggering the micro switch through the axial displacement of the worm.

3. Easy operation and maintenance, realizing on-site and remote control operation.

The gate series are safe to use, reasonable in structure, good in performance, in compliance with standards for water discharge, and easy to debug and maintain; opening and closing equipment, flexible opening and closing, durable, good sealing performance, and a high degree of automation.

It can be widely used in the lifting adjustment of gates, weir gates, lift valves, mud valves and maintenance gates in water conservancy and hydropower projects, river treatment projects, various water supply and drainage projects, and urban sewage treatment projects, all of which have been inspected by the Ministry of Water Resources and quality inspections Department’s permission.

Load test method of hoist

1. The operator of the gate hoist must master the structure, performance and operation methods of the gate hoist, and have certain mechanical knowledge to ensure the normal operation of the machine.

2. Before operation, conduct a comprehensive inspection of the hoisting machine to see if the lubrication of each part is good and whether the bolts are loose.

3. When the gate hoist is running, the operator shall not leave the site, and immediately shut down the machine if there is a problem.

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

5. When in use, it is necessary to inject lubricating oil from the oil injection hole at any time, and always keep enough lubricating oil. The screw must be regularly cleaned of grease and coated with new oil to prevent rust.
