The working principle of electric winch and use
Work
Many kinds of winch, electrical winch, the vehicle engine mechanical power-driven winch and winch with a hydraulic pump operation, etc., to use off-the largest number of electric winch up. Electric winch from the car itself was the motor drive power to drive the noose of. This winch is very convenient because you can stand in any place through the knob on the remote control. It is the biggest advantage is only
There is power to the battery can be used.
However, the winch's power hold engineering promise to only a few horsepower, why such a small power to drag a heavy motor car or other heavy objects on it also? The secret lies in the use of reducer. Even if the power of the motor can only be issued by smaller, but the reducer was able to transform it into a force powerful. It is a different winch manufacturers before using this principle to create a different product.
Market, most of the planetary gear winches are used to do reducer. Planetary gear has the advantage of smaller and produced relatively large reduction ratio, and the gear contact points more, longer service life. Winch are usually installed in a more narrow space, so the smaller the lighter the better. Gear can achieve this requirement, while have a greater reduction ratio, so again ideal.
In short, the work of the internal winch mechanism: from cars to power the first drive motor, while the Houma Da driven rotating drum, drum drive shaft then take the initiative to further drive gear shaft, thus producing a strong torque. Subsequently, the torque is transferred back to drum, drum, it will be driven winch. Between the motor and the reducer has a clutch, through a handle to switch. Within the drum brake unit, when the noose tightened, the drum is automatically locked.
In practice, some aids are essential for safe and smooth when using the winch, such as gloves, safe and protected hands. In addition, if you want winch fixed to a tree, but also a piece of string, hang a u-shaped ears and a tight line pulley. Tape is used to a fixed fulcrum. The ideal length is 1.5-2. O m; u-shaped lug and strap and winch hook can connect. So best to prepare several sizes of lug; with two-or three-line, drag to change direction, you need a tight line pulley. Winch control can be divided into three short steps: installation, a fixed pivot and drag.
Winch installation
Of course, using the winch was started from the installation. This step is not complicated, but it is the most important step, because it is directly related to the subsequent steps and the use of winch effect. The most important note here is the status of rope drum, and the use before the start of the process must ensure the uniformity of winding rope. Specific installation process is as follows:
1, insert the remote control. Connect the remote end of the first insert winch.
2, Do not let the remote connection hanging. If you are a motorist, the driver's seat to operate the remote control, then the extra connections around the side rear view mirror in the car, working together will be much more convenient.
3, opened the noose, the noose with a remote control to open out a bit and then installed in the side of the rope winch hook.
4, open the clutch. Note that we must open the hook to open the clutch later.
5, hold the rope hook hands. Will pull the rope from the drum when the hook with one hand hold, so no matter how long the twisted Sola, will not not reach the hook.
6, the rope pulled pivot, the locking clutch.
Thus winch ready.
Fixed-fulcrum
If you want car pulled forward, there must be a safe place fixed fulcrum, the fulcrum must also be able to bear the full weight of vehicles. The most basic principles of movement towards car pulled in front, do not appear angle. Off-road driving, the most commonly used is the fulcrum of the tree. However, if another vehicle with a winch to rescue trapped cars, rescue vehicles can also be used as the fulcrum, but in this case, we must block the wheels, so they can not roll, that is to ensure the rescue vehicle will not move.
Regardless of what kind of winch, without security, pivot, you can not give full play to their potential. In other words, the fixed pivot is a crucial step when using the winch.
When using the winch, but also a strap to connect the winch, the fulcrum and the noose hanging hook and U-shaped ears. If you do not have enough power winch with single drag heavy objects, you need to use the lane to enhance its efforts, this time also need a tight line pulley.
Another point to note that when using the tree as the fulcrum, to use the widest part of the tape so that tape to the bark in Le destruction of trees, and be sure to tape the left and right ends of both sides were tied at the hanging ears, on both sides length to the same tape.
Start drag
With a winch to pull the specific steps:
1, first check the drum. Before you begin, make sure the noose neatly around the drum wheel.
2, if the noose emerge, should prevent it from swinging back and forth. If the rope snapped, and the rope lashing back and forth can be very dangerous. However, the risk can be avoided if the taut rope put a pad on the line.
3, start dragging, if his car with twist Sola, and you have to drive in the car, the best a man in the car to help you. In this way, the driver can command the vehicle's instructions, in the vehicle control winch.
4, if the rope twisted together, and must bring it opened. Noose around the drum is easy to cross, or when one side becomes uneven. Therefore, pay close attention to its status.
5, when the vehicle can move around, the drag is complete. Once back on flat land, to check the status of vehicles and lines. If you can not start the car by external forces, using winch drag the process is over.
6, the rope was curled. Tighten noose, carefully return it. If the noose on the cross in the drum or distorted, first completely solved, and then recoiling.
7, and finally put away the hook. When the noose only the last point, the winch hook tied to the side. Then roll up the remaining little rope to hook to suppress.
8 Remove the remote control.
