Winch hoist is a kind of automatic closing machine, which belongs to a new type of hydraulic engineering special mechanical tool（ It is connected with the gate by using the steel cable or the steel cable pulley block as the spreader. Through the gear transmission system, the winch can wind and put the steel cable to drive the lifting machine. It is also called the wire rope fixed winch. Its structure is relatively simple, easy to manufacture, easy to maintain and repair, and is widely used in the opening and closing of various types of gates.
The hoist is divided into manual hoist and electric hoist. Now the main electric hoist. The electric hoist is composed of motor, coupling, brake, gearbox, and drum, which are installed on the frame together.
Winch hoist is widely used in water conservancy project gate opening and closing is farmland irrigation, aquaculture, agricultural economic development zone, sewage treatment plant, hydro-power station, reservoir, river (sluice, dam, channel, culvert, pipeline), and other water inlet and outlet sluice supporting machinery, mountain area, plain, with or without electricity area can use! Northeast China is a big province of the rice industry, endless rice fields, until the planting season, it is difficult to complete so many tasks only by human seeding, so at this time we need to use this professional mechanical equipment which is helpful to agricultural development – winch hoist.
Winch hoist generally has two kinds of layout: single lifting point and double lifting point. The former is composed of pulley block, drum, transmission mechanism, braking device, frame, height indicating device, limiting device, and load limiting device; It is driven by manpower, motor, or internal combustion engine; The capacity t is 65 ~ 5000 kn and the lift is 8 ~ 34m. The double lifting point arrangement is composed of two symmetrical single lifting point hoists (only when the capacity is small, the driving device can be placed on one side); The two sets are connected by rigid synchronous shaft to ensure the synchronous lifting of two lifting points. When the distance between the lifting points is large, the synchronous operation of the motor can be used to make the two lifting points rise and fall synchronously. The hydraulic hoist system uses liquid as the medium of power transmission to push the piston and piston rod to lift the gate. It has the advantages of small volume, lightweight, compact cloth, large opening and closing capacity, stable operation, and centralized operation equipment.
Electric winch is mainly used for winding, pulling, and towing heavy cargoes. Such as all kinds of large and medium-sized concrete, steel structure, and mechanical equipment installation, and dismantling. Suitable for construction and installation company, mining area, factory civil construction, and installation project. According to lifting speed, the electric winch can be divided into fast speed electric winch and low-speed electric winch.
