Detailed Description

Reference will now be made in detail to various embodiments of the utility model, examples of which are illustrated in the accompanying drawings and described below. While the utility model will be described in conjunction with the exemplary embodiments, it will be understood that the present description is not intended to limit the utility model to these exemplary embodiments. On the contrary, the utility model is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the utility model as defined by the appended claims.

The following describes the trailing cable anti-sway device of the present utility model with reference to fig. 1 to 7.

Fig. 1 shows a schematic structural view of a trailing cable anti-sway device according to the present utility model, comprising: an upper bracket 1, a lower bracket 2, a steel wire rope 3, an intermediate bracket 4 and a tensioning piece 5.

Fig. 2 shows a schematic installation of a trailing cable anti-sway device of the present utility model, wherein the trailing cable anti-sway device is installed on the side of a hoistway. Referring to fig. 1 and 2, an upper bracket 1 is fixed to an upper portion of an elevator hoistway. The lower bracket 2 is fixed to the lower part of the elevator shaft. The intermediate bracket 4 is fixed to the middle part of the elevator shaft and is arranged between the upper bracket 1 and the lower bracket 2. A wire rope 3 is wound between the upper and lower brackets 1 and 2 and wound around the upper and lower brackets 1 and 2 and passed through the intermediate bracket 4 during winding, and the end of the wire rope 3 is connected to the tension member 5.

In the trailing cable anti-sway device of the present utility model, the number of intermediate brackets 4 is optional, for example, the intermediate brackets 4 may be one or more than one. When the intermediate brackets 4 are plural, these intermediate brackets may be provided at intervals in the extending direction of the wire rope 3 between the upper bracket 1 and the lower bracket 2 to better prevent the wire rope 3 from swinging, as shown in fig. 1.

In the trailing cable anti-sway device of the present utility model, the structures of the upper bracket 1 and the lower bracket 2 are identical, and each of the upper bracket 1 and the lower bracket 2 includes the nylon wheel 11, the wire rope 3 can be wound around the nylon wheel 11 between the upper bracket 1 and the lower bracket 2, and thus the abrasion of the wire rope 3 can be effectively prevented, see fig. 3.

In the trailing cable anti-sway device of the present utility model, the intermediate brackets 4 may comprise a wrapped wire 41 configured to retain and support the wire rope 3 at the intermediate brackets 4 to better prevent the wire rope 3 from swaying, see fig. 4.

In the trailing cable anti-sway device of the present utility model, one wire rope 3 is plastic-coated. One end of the steel wire rope 3 is fixed by a rope clamp 31 after bypassing the nylon wheels 11 at the upper bracket 1, and the other end is fixed to the tensioning piece 5 by a rope clamp 52 through a hanging ring 51 after bypassing the two nylon wheels 11 of the upper bracket 1 upwards by bypassing the two nylon wheels 21 of the lower bracket 2, as shown in fig. 5-7. The wire rope 3 can thus be wound at least one turn between the upper and lower brackets 1, 2 and its end is suspended with the tension member 5.

In the trailing cable anti-sway device of the present utility model, the intermediate section of one wire rope 3 passes through the wound wire 41 of the intermediate bracket 4, whereby the one wire rope 3 can be held at the intermediate bracket 4 via the wound wire 41, which can allow the wire rope 3 to be better fixed, see fig. 4.

In the present trailing cable anti-sway device, the tension member 5 may be a tension weight made of steel or a composite material, thereby being capable of providing sufficient tension to the wire rope 3 so as to put the wire rope 3 in a tensioned state or a strained state to prevent the wire rope 3 from sway due to slackening.

Alternatively, the tensioning member 5 may be a tensioning spring made of an elastic material, which is also capable of providing sufficient tension to the wire rope 3, thereby putting the wire rope 3 in tension or in tension to prevent the wire rope 3 from swinging, and thus the travelling cable from swinging in the hoistway.

In summary, the trailing cable anti-swing device of the utility model prevents the trailing cable 6 from swinging in the elevator shaft by suspending the tensioning piece 5 at the tail end of the trailing cable after one steel wire rope 3 winds around the upper bracket 1 and the lower bracket 2, has simple structure, reduces installation parts, simplifies installation flow, has lower cost and can efficiently prevent the trailing cable from swinging in the shaft.
