Description

Technical Field

[0001] This utility model relates to the field of cable hoisting technology, and more specifically, to a cable support device. Background Technology

[0002] Cable-stayed gantry systems typically have large spans and significant distances between the antenna trolley and the slewing pulley on the tower. Consequently, the lifting and traction wire ropes experience high tension under a given sag, increasing the counterweight at the lifting points and the traction force on the traction rope. To effectively reduce the counterweight at the lifting points and the traction force on the front traction rope, cable support devices are generally added to the basic components of the cable-stayed system. Cable support devices are typically installed at regular intervals, connected to adjacent devices, to the antenna trolley, and to the slewing pulley at the top of the tower by wire ropes. The spacing between cable support devices is often small, resulting in a large number of devices and presenting safety risks and high costs. Utility Model Content

[0016] Example

[0017] like Figure 1-2As shown, this embodiment mainly discloses a cable support device, including a pair of main bodies. The main body includes: an upper support 1, which includes a circulating wheel 11 and a load-bearing wheel 12 for connecting a load-bearing cable 120. The circulating wheel 11 and the load-bearing wheel 12 are connected by a pin and a bushing. The circulating wheel 11 is located on both sides of the upper support 1, and the load-bearing wheel 12 is located in the middle of the upper support 1. A circulating cable 110 is connected between the circulating wheels 11 in the same group; and a lower support 2, which is connected to the upper support 1 by a pin. The lower support 2 includes, from top to bottom, a traction cable 210 for connecting a traction cable 210. The structure includes a wheel 21 and a lifting wheel 22 for connecting the lifting cable 220; specifically, there is an anchorage of a load-bearing cable 120 between the two towers, and multiple load-bearing wheels 12 and circulating wheels 11 are arranged side by side. The load-bearing wheels 12 are placed on the load-bearing cable 120 so that the main body can slide along the load-bearing cable 120; the single-sided circulating cable 110 passes through the upper part of a certain main body circulating wheel 11, goes around another main body circulating wheel 11 in the same group, and then goes back from the lower part to form a closed loop structure; or, the single-sided circulating cable 110 is tied around a certain main body circulating wheel 11 once, and then goes around another main body circulating wheel 11 in the same group to tie... The loop connects the paired components. Typically, the cable supports are located on both sides of the antenna carriage, meaning the paired cable supports are positioned symmetrically on both sides of the antenna carriage. Furthermore, multiple sets can be installed on the load-bearing cable 120, for example, three sets of cable supports, numbered A1, B1, C1, C2, B2, and A2 from left to right. A1 and A2 form one set, B1 and B2 form another, and C1 and C2 form a third. Each set is independent. The antenna carriage can be positioned between C1 and C2. When the antenna carriage moves to the left, it pushes C1 to the left, thus connecting the loop cable. 110 drives C2 to move to the left. When the antenna trolley moves further to the left, the antenna trolley pushes B1 to move to the left through C1. The circulating cable 110 drives B2 to move to the left as well. This process continues until the antenna trolley moves to the right, and the movement is similar. By setting up the circulating wheel 11, the circulating cable 110 is connected to the circulating wheels 11 of the two cable carriers in the same group. This increases the distance between the two cable carriers, which greatly reduces the number of cable carriers used. While ensuring functionality, this greatly reduces costs and installation safety risks.

[0018] Furthermore, in specific implementation, partitions are provided on both sides of the circulating wheel 11 and the load-bearing wheel 12, and wall plates are provided on both sides of the traction wheel 21 and the lifting wheel 22, and are connected accordingly by pins and bushings; specifically, friction plates are provided between the partitions and the circulating wheel 11 and the load-bearing wheel 12, and between the wall plates and the traction wheel 21 and the lifting wheel 22, which improves the durability of the structure.

[0019] Furthermore, in specific implementation, the above-mentioned body provided in this utility model embodiment is inverted mountain shape, with a symmetrical and stable structure, ensuring the strength of the structure, and forming an upper and lower layered structure, effectively avoiding the risk of entanglement between the cables.

[0020] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
