Description

Technical Field

[0001] The utility model relates to a main cable anti-corrosion device for a suspension bridge, belongs to the field of suspension bridge devices, and particularly relates to a main cable dehumidification device in a saddle groove. Background Art

[0002] The main cable of a suspension bridge is the main load-bearing and force-transmitting component of the suspension bridge. Due to its long-term exposure to the bridge environment, it is easily affected by moisture and corroded, which in turn affects the service life of the main cable. In addition, since the main cable is difficult to replace after the construction of a suspension bridge, protective and dehumidification measures for the main cable are an important part of extending the service life of the bridge.

[0003] The existing main cable dehumidification and corrosion protection is achieved by supplying dry air into the main cable. Specifically, S-shaped galvanized steel wire is wrapped around the outer surface of the main cable, and multiple layers of anti-corrosion coating are applied on the outer surface. Sealant and paint are applied to the end face of the cable clamp. When the dry air flows through the gap of the main cable, it removes moisture from the main cable. However, when the main cable passes through the cable sleeve and enters the saddle chamber of the main tower, there is no S-shaped galvanized steel wire and anti-corrosion coating on the outside of the main cable. The main cable is composed of several steel cables as a group. The steel wire strands are tied into a regular hexagon with a fixed binding tape and pass through the main cable saddle groove and the partition. The existing main cable dehumidification method cannot produce a dehumidification effect on the steel wire strands between the main cable saddle groove and the partition. Although there is a dehumidification pipe in the saddle chamber, the dry air cannot enter the moisture in the steel wire strands between the main cable saddle groove and the partition. In addition, zinc fillers are pressed on the steel wire strands, resulting in poor dehumidification effect on the steel wire strands between the main cable saddle groove and the partition.

[0004] The patent application document with application number 202311605763.4 and application date February 2, 2024, discloses a method for installing the central ventilation duct of the main cable of a large-span suspension bridge. This scheme dehumidifies the main cable by actively supplying air into the cable. Although this method can improve the dehumidification efficiency to a certain extent, its dehumidification effect is positively correlated with the power of the active air supply equipment. There is no further optimization of the circulation route of the dry air, resulting in poor dehumidification effect. Summary of the Invention

[0048] The lower ends of both sides of the cross air supply pipe 213 are respectively located above the air outlet holes 214 of the first air supply pipe 211 and the second air supply pipe 212 .

[0049] The distance between the vent hole 31 and the bottom of the wall panel 2 or the partition board 3 is 1.5 to 1.8 times the height of the cable strand 4 ; the position of the air outlet hole 214 corresponds to that of the vent hole 31 .

[0054] Example 1:

[0055] See also Figures 1-8 A main cable dehumidification device in a saddle trough comprises: a main cable saddle body 1, a wall panel 2, a partition panel 3, and a cable strand 4; the cable strand 4 is arranged at the bottom of the saddle trough 11; the wall panels 2 and the partition panels 3 are alternately arranged in the saddle trough 11 of the main cable saddle body 1; an air supply pipe group 21 is arranged in the wall panels 2 on both sides of the center line of the saddle trough 11; the air supply pipe group 21 includes a first air supply pipe 211, a second air supply pipe 212 and a cross air supply pipe 213; the first air supply pipe 211 and the second air supply pipe 212 are both vertically penetrated and arranged The first air supply pipe 211 and the second air supply pipe 212 are connected to each other by a cross air supply pipe 213; the bottoms of the first air supply pipe 211 and the second air supply pipe 212 are provided with air outlet holes 214; the bottoms of the wall panel 2 and the partition 3 are provided with air vents 31 along their thickness direction, and the air outlet holes 214 are connected to the air vents 31; the inner walls of the first air supply pipe 211, the second air supply pipe 212 and the cross air supply pipe 213 are provided with threaded grooves 5.

[0056] See also Figure 8In application, in the traditional air supply structure, dry air enters from the top of the pipeline and flows out from the bottom. Although this can deliver a certain amount of dry air to the inside of the saddle trough 11, due to the stacked structure of the wall panels 2, partitions 3, cables 4, etc., the air cannot flow to various parts as quickly as possible, resulting in more dry air at the bottom outlet of the pipeline and relatively less dry air in other parts, which in turn makes it difficult to remove moisture in some areas of the saddle trough 11. In this solution, dry air enters through the first air supply pipe 211 and the second air supply pipe 212 on the wall panel 2, and flows out from the bottom ends of the first air supply pipe 211 and the second air supply pipe 212 and the air outlet hole 214 at the lower part. Then, the dry air flows into the gap between the adjacent partitions 3 through the air vents 31, and gradually penetrates and circulates outward, thereby taking away the moisture inside all the steel wire strands in the saddle groove 11, achieving the effect of dehumidification and anti-corrosion; in this process, the air entering from the first air supply pipe 211 will flow to the second air supply pipe 212 through the cross air supply pipe 213, and flow to both sides from the bottom end of the second air supply pipe 212; and the air entering from the first air supply pipe 211 will flow to the second air supply pipe 212 through the cross air supply pipe 213, and flow to both sides from the bottom end of the second air supply pipe 212; The air entering the second air supply pipe 212 will flow to the bottom end of the first air supply pipe 211 through the cross air supply pipe 213, and flow to both sides from the bottom end of the first air supply pipe 211; since the main cable saddle body 1 is long and the cable strands 4 are arranged along its length, the cross air supply pipe 213 can transport dry air to various parts of the saddle groove 11 as quickly as possible, so that the overall dryness of the saddle groove 11 is more uniform; in addition, the spiral groove 5 arranged on the inner wall of the pipe can not only provide guidance for the flow path of the air, but also cause the air to generate a rotational motion when entering, thereby accelerating the flow speed of the air and thus better removing moisture.

[0057] Example 2:

[0058] The basic content is the same as Example 1, except that:

[0059] The first air supply pipe 211 extends from the top to the bottom of the wall panel 2, and a first screw hole seat 216 is provided at the top of the first air supply pipe 211. The second air supply pipe 212 extends from the top to the bottom of the wall panel 2, and a second screw hole seat 217 is provided at the top of the second air supply pipe 212. A first tapered pipe threaded hole 218 is vertically formed in the first screw hole seat 216, and the first tapered pipe threaded hole 218 is connected to the first air supply pipe 211. A second tapered pipe threaded hole 219 is vertically formed in the second screw hole seat 217, and the second tapered pipe threaded hole 219 is connected to the second air supply pipe 212. The first tapered pipe threaded hole 218 is connected to the first air pipe connector 6, and the second tapered pipe threaded hole 219 is connected to the second air pipe connector 61.

[0060] In use, the first tapered threaded hole 218 defined in the first screw hole seat 216 is designed to facilitate the installation of other devices, such as the first air line connector 6. This allows for connection to an active gas delivery device (e.g., an air compressor) through the first air line connector 6, thereby providing more dry air to the interior of the line. This allows for rapid dehumidification of the saddle groove 11 in conditions such as heavy rain. Furthermore, a passive air intake device, such as a hood, may be provided at the top of the first screw hole seat 216 to provide passive air intake to the line, thereby improving the efficiency of dry air circulation.

[0061] However, even without adding an active or passive gas delivery device, the pipeline structure in this solution can still provide an efficient flow path for dry air and also improve the efficiency of moisture discharge.

[0062] Example 3:

[0063] The basic content is the same as Example 1, except that:

[0064] The cross air supply pipe 213 is in an X-shape, and the upper and lower ends of one side of the cross air supply pipe 213 are connected to the upper and lower ends of the first air supply pipe 211, and the upper and lower ends of the other side are connected to the upper and lower ends of the second air supply pipe 212;

[0065] The lower ends of the cross-air supply pipes 213 are located above the outlet holes 214 of the first and second air supply pipes 211, 212, respectively. The distance between the vent holes 31 and the bottom of the wall panel 2 or partition 3 is 1.5 to 1.8 times the height of the cable strands 4. The outlet holes 214 correspond to the positions of the vent holes 31. Multiple vent holes 31 are provided, evenly spaced along the length of the wall panel 2 or partition 3.

[0066] In application, the lower ends of the X-shaped cross air supply pipes 213 are respectively located above the air outlet holes 214 of the first air supply pipe 211 and the second air supply pipe 212. Figure 8 As shown, dry air can enter the air outlet hole 214 and the bottom end of the air supply pipe at the same time. Since the interior of the saddle groove 11 is not closed and the wall panel 2 and the partition 3 are not completely close to each other, dry air can continuously flow outward through the air vent 31 into the gap between them, thereby taking away the moisture retained in the gap.

[0067] like Figure 2 As shown, this solution is usually set in the middle of the main rope saddle body 1, and several ventilation holes 31 are evenly spaced along the direction of the wall panel 2 or partition 3. This not only provides an air circulation channel, but also can further enhance the effect by adding multiple devices when necessary.

[0068] In applications, such as Figure 5 As shown, because the density of moisture is greater than that of air, moisture generally accumulates at the bottom of the saddle groove 11. The dehumidification effect is better when the distance H between the vent hole 31 and the bottom of the wall panel 2 is generally 1.5-1.8 times the height of the cable strand 4. Accordingly, the setting height of the air outlet hole 214 corresponds to the position of the vent hole 31.

[0069] Example 4:

[0070] The basic content is the same as Example 1, except that:

[0071] The bottom surfaces of the wall panels 2 and partitions 3, where they contact the saddle groove 11, are each provided with a first chamfered structure 22 and a second chamfered structure 23. The bottom ends of the first and second air supply pipes 211, 212 are both connected to the first chamfered structure 22. The chamfering distance of the first chamfered structure 22 is greater than that of the second chamfered structure 23. The wall panels 2 and partitions 3 are mirrored from the centerline of the saddle groove 11. The first chamfered structure 22 is located closer to the centerline of the saddle groove 11, while the second chamfered structure 23 is located on the opposite side of the first chamfered structure 22.

[0072] In applications, such as Figure 5 As shown, both sides of the bottom surface of the wall panel 2 and the partition 3 are chamfered. Figure 7 The second chamfered structure 23 abuts against the corner of the saddle groove 11, so that dry air can flow through the gap between the second chamfered structure 23 and the saddle groove 11, further improving the air flow efficiency, and the first chamfered structure 22 facilitates welding and fixing the wall panel 2, partition 3 and saddle groove 11.

[0073] The wall panels 2 and partitions 3 in this embodiment are distributed in a mirror image on both sides of the center line of the saddle groove 11. Figure 4 As shown. Further, Figure 7 As shown, the chamfered structures on both sides of the saddle groove 11 centerline are also mirrored. For example, if a wall panel 2 is located to the left of the saddle groove 11 centerline, the side facing the saddle groove 11 centerline will have the first chamfered structure 22, while the opposite side will have the second chamfered structure 23. Similarly, if the wall panel 2 is located to the right of the saddle groove 11 centerline, the side facing the saddle groove 11 centerline will also have the first chamfered structure 22.

[0074] It should be noted that both ends of the first air supply pipe 211 and the second air supply pipe 212 in this solution are open, rather than closed at one end or both ends. The concept of pipeline is more common in the prior art, so it is not emphasized. Figure 5 It can also be seen that the bottom ends of the first air supply pipe 211 and the second air supply pipe 212 in this solution are connected to the outside.

[0075] In this solution, according to the external dimensions of the main cable saddle body 1 and the size of the saddle groove, the wall panel 2 and the partition 3 can be set as an integral type or in the form of multiple pieces or multiple layers spliced ​​together.

[0076] For the main cable saddle body 1 with larger external dimensions, the air inlet of the air inlet pipe on the corresponding wall panel 2 can also be set to 2 or more, and the matching screw hole seats must also be set to 2 or more. The number of air vents in the thickness direction of the wall panel 2 can also be increased accordingly. The number of partitions 3 can also be appropriately reduced, and the number of wall panels 2 can be increased to increase the flow rate of dry air injected into the wire rope strands.

[0077] The main cable saddle body 1 can be an integrally cast structure, a welded structure, or a combination of a side span saddle body and a mid-span saddle body. The side span saddle body and the mid-span saddle body can be cast structures or cast-welded structures.

[0078] Although the embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are illustrative and cannot be interpreted as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
