Description

Rope guide for easy threading of wire ropes

The present invention relates to a rope guide used to assist in retracting a steel rope, and in particular, to a rope guide that is easy to thread a steel rope.

An existing rope guide is suitable for being installed on a winch for winding up a steel rope and for the steel rope to pass through. The rope guide has a base body and a plurality of wire guide wheels. The base body has an inner side that is U-shaped and defines an opening approximately equal to the diameter of the steel cable. The wire pulleys are spaced apart from the inner side. When operating the winch to retract the wire rope, the wire rope needs to be inserted into the opening and passed between the wire pulleys, and then the winch is rotated to retract the wire rope, whereby the wire pulleys can prevent the wire rope from retracting. When the steel rope is rolled, it will jump, causing it to become entangled and make the winding unsmooth.

However, when using the rope guide, it takes time and effort to insert the steel rope into the opening, and then fix the steel rope between the guide wheels. After the winding is completed, the steel rope needs to be used again next time. Pull hard on the cable to remove it from the opening. Therefore, this rope guide has the disadvantage of being time-consuming and laborious to use.

Therefore, an object of the present invention is to provide a rope guide that is easy to use and easy to thread a steel rope.

Therefore, the rope guide for easy threading of steel ropes according to the present invention is suitable for being installed on a rope guide seat and for threading a steel rope. The rope guide for easy threading of steel ropes includes a first shell, a second shell, a Pivot unit, a lock unit, a guide wheel unit, and an adjustment unit.

The first housing is arranged on the guide rope base. The second housing is pivotally connected to the first housing and cooperates with the first housing to define a chamber open on opposite sides for the steel cable to be movably inserted. The pivot unit includes a first pivot portion provided on the first housing, and a second pivot portion provided on the second housing and pivotally connected to the first pivot portion. The locking unit includes a first locking component disposed on the side of the first housing opposite the first pivot portion, and a detachable latch disposed on the side of the second housing opposite the second pivot portion. Provide a second locking component of the first locking component.

Wherein, the first housing can rotate relative to the second housing and change between an open position and a closed position. In the open position, the first housing can rotate relative to the second housing, and the third housing can rotate relative to the second housing. A locking part is away from the second locking part so that the steel cable can be placed between the first housing and the second housing. When in the closed position, the first locking part engages the second locking part. components, the first housing abuts the second housing and jointly defines the chamber.

The effect of the present invention is that when the first housing is in the open position, the The steel cable can be placed between the first housing and the second housing, and the steel cable can move through the chamber in the closed position, so that the steel cable can be retracted more simply and conveniently.
