Reverse the structural improvement of the hook piece.

According to the lifting device, the lifting device is a device for conveying low-level articles to a high place. The lifting device is provided with a loading platform, and the loading platform is connected to the lifting mechanism, and then the steel cable is driven by the hand lever or the electric winch to tighten the lifting mechanism. Raise the stage up to the point of delivering the goods to a high place. If the items are sent to the ground, the reverse operation is performed.

Because the items carried by the lifting device generally weigh several tens of kilograms or even hundreds of kilograms, the structure design of the lifting device improves the bearing capacity, how to reduce wear, disperse the force, and how to stabilize the stability of the lifting process. All have some thoughts. However, in order to avoid the falling or falling speed of the loading platform during the ascending process, the lifting device generally uses the electric winch to control its rotation speed and torque, and cooperates with the anti-reverse structure to limit the electric winch, and the anti-reverse structure improves the stability. It’s a pity that there is no part in it.

In addition, when the lifting device is in operation, the steel cable is suspended from the side of the winch, and in order to wind the steel cable in the winch on average, the steel cable needs to be moved back and forth on the side of the winch rotating drum. However, the motor of the lifting device has a distance of at least one floor from the destination of the cargo, and the cable can only be limited at one end of the motor and the destination, so that the cable is easily shaken excessively and is separated from the winding range of the winch. In addition, after long-term use of the cable or after being worn by external force, local wire breakage or splitting often occurs, and this situation is more likely to cause the cable to be separated from the winch winding range, so that the user has to replace the cable.

The advantages of delaying the old frequency of the rope, etc., and the detailed explanation will be explained below.

Please refer to the first to sixth figures at the same time, which is a perspective view to a state of use of the preferred embodiment of the present invention. When the above components are assembled, the anti-reverse hook of the present invention can be clearly seen from the figure. sheet The power component 6 is pivotally disposed on the power component 6 (the power component 6 is a winch in the embodiment). In general, the power component 6 drives the winding seat 62 to rotate and release the rope by using a driving device 61 (for example, a motor). Plays the anti-reverse hook when the rope is released.

When the rope is released and the driving device 61 is not stopped, if the anti-reverse hook piece is not installed, the winch is forcibly rotated, causing the clutch to slip or be damaged, and the anti-reverse hook piece can be present. The inverted hook portion 11 of the anti-reverse sheet 1 is restrained from its abnormal rotation. Specifically, the rope that is placed on the side of the winch is continuously pushed toward the extending portion 3 on the side of the interlocking rod 2 by the pulling of the driving device 61, so that the anti-reverse sheet 1 is in the anti-reverse limit portion 63. The side standby hook, once the reverse action occurs, the hook portion 11 is the anti-reverse limit portion 63, and has an anti-reverse effect. In the normal operation, in order to maintain the normal operation of the anti-reaction sheet 1, it is necessary to ensure that the rope continues to push the extension portion 3. However, the amplitude of the hanging rope is more difficult to control, so the limit rod body 4 is shared with the extension portion 3. A limit space 5 is isolated to limit the rope within the limit space 5. And because the extension 3 is parallel to the winding seat 62, and the length of the extension 3 is not greater than the length of the winding seat 62, the winding rope of the winding seat 62 can be assisted, thereby stabilizing the overall movement fluency and movement. stability.
