A preset tensioning force is applied to the steel wire rope by adjusting the positions of the three tensioning wheels in the horizontal direction.

[0005] Preferably, the outer circumferential surface of the tensioning wheel is a U-shaped groove adapted to the steel wire rope and is made of wear-resistant and vibration-damping material.

[0006] Preferably, the length of the flexible rod is adjustable.

Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific implementation manners. The details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without departing from the general design concept of the invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited only to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0013] Embodiment 1

[0014] As Figure 1 shown, this embodiment provides an elevator steel wire rope vibration damping device, which includes a base 5, a connecting rod 4, a limiting plate 3, a tensioning wheel assembly 2, a vibration damping hammer 7, and a flexible rod 6. In this embodiment, the elevator steel wire rope vibration damping device is used to damp the steel wire rope 1 connecting the car 10, and the base 5 is fixed on the car top beam 8 at the top of the car. In another implementation manner, the elevator steel wire rope vibration damping device can also be used to damp the steel wire rope connecting the counterweight. At this time, the base is fixed on the frame at the top of the counterweight. The vibration damping hammer 7 is fixed on the limiting plate 3 through the flexible rod 6.

[0015] The limiting plate 3 is fixed on two bases 5 through two connecting rods 4. The tensioning wheel assembly 2 is fixed on the limiting plate 3. In this embodiment, there are two groups of tensioning wheel assemblies 2, which respectively tension the two groups of steel wire ropes entering and leaving the car top wheel 9.

[0016] In this embodiment, there are three tensioning wheels in each group of tensioning wheel assemblies. The tensioning wheels are rotatably fixed on the limiting plate 3 through rolling bearings and are arranged vertically. The upper tensioning wheel and the lower tensioning wheel are on one side of the steel wire rope, and the middle tensioning wheel is on the other side of the steel wire rope. A preset tensioning force is applied to the steel wire rope by adjusting the positions of the three tensioning wheels in the horizontal direction. The outer circumferential surface of the tensioning wheel is a U-shaped groove adapted to the steel wire rope and is made of wear-resistant and vibration-damping material.

[0017] The flexibility of the flexible rod 6 can be changed by adjusting its length and thickness. The flexible rod 6 and the vibration damping hammer 7 are both symmetrically arranged. The mass of the vibration damping hammer 7 can also be adjusted.

[0018] The bottom of the base 5 is provided with vibration damping rubber.

[0019] The elevator steel wire rope vibration damping device of this embodiment, from the perspective of the vibration transmission path, dissipates the vibration energy of the steel wire rope through three ways: the tensioning wheel, the flexible rod and the damping hammer, the connecting rod and the base, and can greatly reduce the vibration problem of the steel wire rope during elevator operation.

[0020] The above has described the present invention in detail through specific implementation manners and embodiments, but these do not constitute limitations to the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many deformations and improvements, which should also be regarded as the protection scope of the present invention.
