Hydraulic winch for drilling platform Yuansheng quality assurance construction winch manufacture

  Hydraulic winch for drilling platform   Yuansheng quality assurance construction hoist manufacturer   What is a winch   Winch, also known as winch, is a device that drives the drum and winding rope by human or mechanical power to complete the traction work
Heavy objects can be lifted vertically, pulled horizontally or tilted
To put it bluntly, it is a kind of crane, which rolls up the rope through the drum to achieve the effect of lifting heavy objects
It is a crane with good speed regulation What are the main structures and working principles of mine winches and mine hoists   Mine winch is a kind of equipment used in mines to achieve its working purpose with the help of steel wire rope traction
Including “ Friction wheel transport winch   Winches are divided into manual, electric and hydraulic types according to power
It can be classified into construction winches and marine winches Winches can be divided into marine winches, engineering winches, mining winches, cable winches, etc
according to their functions It is divided into single drum and double drum according to the drum form According to the drum distribution, it can be divided into parallel double drums and front and rear double drums Special types of winches include: variable frequency winch, double drum winch, hand brake lever type double brake winch, winch with limiter, electric control winch, electric control hand brake clutch winch, large double drum double brake winch, large external gear winch, large hydraulic winch, large external gear wheel winch with rope guide, double traction wheel winch, large hydraulic double drum double brake winch, variable frequency rope groove winch with limiter Manual winch   A stopper (ratchet wheel and pawl) is installed on the transmission mechanism of the handle rotation of the manual winch to keep the weight at the required position
The manual winch used for assembling or lifting heavy objects shall also be equipped with safety handle and brake
Manual winches are generally used in places with small lifting capacity, poor facilities or no power supply Electric winch   Electric winches are widely used in places with heavy work and large traction
The motor of the single drum electric winch (Figure) drives the drum through the reducer, and a brake is installed between the motor and the input shaft of the reducer
In order to meet the needs of lifting, traction, rotation and other operations, there are also winches with double drum and multi drum devices
Generally, winches with rated load less than 10t can be designed as electric winches Hydraulic winch   Hydraulic winches are mainly winches with large rated load
Generally, winches of more than 10t to 5000t are designed as hydraulic winches For example, the rescue equipment installed on the helicopter is mainly used to lift and put down people or objects
It has its own power and can be controlled
When the helicopter hovers at a high altitude, it can lift and put down people or objects by retracting and releasing the steel cable through the control of the winch operator Mine hoist, winch, is a kind of large-scale hoisting mechanical equipment
The motor drives the mechanical equipment to drive the steel wire rope to drive the container to rise and fall in the shaft to complete the conveying task
Mine hoist is evolved from the original water lifting tools
Modern mine hoists have large lifting capacity, high speed and high safety
They have developed into fully automatic heavy mining machinery controlled by computer Mine hoist is mainly composed of motor, reducer, drum (or friction wheel), braking system, depth indication system,   The speed measuring and speed limiting system is composed of the speed measuring and speed limiting system, etc
, and is driven by AC or DC motor
According to the working principle of hoisting wire rope, it is divided into winding mine hoist and friction mine hoist
There are two types of winding mine hoists: single drum and double drum
The winding mode of steel wire rope on the drum is similar to that of general winches
Most single cylinders have only one steel wire rope connected to a container
Each drum of the double drum is equipped with a steel wire rope to connect two containers
During operation, one container rises and the other container falls
Winding mine hoists are mostly used in mines with an annual output of less than 1
2 million tons and a well depth of less than 400 meters
The lifting rope of the friction mine hoist is hung on the friction wheel, and the friction with the friction wheel liner is used to raise the container
Both ends of the lifting rope are respectively connected with a container, or one end is connected with a container, and the other end is connected with a counterweight
Friction mine hoists are divided into tower friction mine hoists (the machine room is set on the tower at the top of the shaft) and floor friction mine hoists (the machine room is directly set on the ground) according to the layout
According to the number of hoisting ropes, it is divided into single rope friction mine hoist and multi rope friction mine hoist
The advantages of the latter are: the thinner steel wire rope and the friction wheel with smaller diameter can be used, so the size of the unit is small and easy to manufacture; High speed, large lifting capacity and good safety
Most of the shafts with an annual output of more than 1
2 million tons and a shaft depth of less than 2100 meters use this kind of hoist
