Description

Technical Field

[0001] This utility model relates to the field of caisson positioning technology, and in particular to a cable launching and retracting device for caisson positioning. Background Technology

[0002] In the field of bridge construction, the use of caissons as bridge foundations is becoming increasingly common, especially in the construction of ultra-long-span bridges in marine environments. Due to its structural stability, excellent load-bearing capacity, and strong adaptability to complex geological conditions, caisson foundations have become the first choice for main pier or anchorage foundations.

[0003] Under the combined effects of wind, waves, and currents, the positioning cables of large caissons in the sea will generate a large cable force, and large-diameter cables are often used. However, the traditional method of relying on jacks to raise and lower the cables is too weak, and large-diameter cables are difficult to bend and are prone to twisting, making it impossible to achieve precise positioning of the caisson.

Detailed Implementation

[0030] The following is combined Figure 1-4This utility model will be described in detail.

[0031] This embodiment provides a cable reeling and launching device for caisson positioning, such as... Figures 1 to 3 As shown, the structure includes a platform 30, several anchoring devices, several cable assemblies 20, and several retrieval devices. The platform 30 is located on top of the caisson 301 and is used for construction. The anchoring devices include several anchor piles 10, spaced apart on the bare rock seabed surrounding the foundation of the caisson 301, capable of resisting the buoyancy of the water flow and providing strong pull-out resistance. Each anchor pile 10 is connected to a corresponding cable assembly 20, with one end of each cable assembly 20 connected to an anchor pile 10 and the other end connected to a corresponding retrieval device. Each retrieval device is located on the platform 30 and corresponds one-to-one with a cable assembly 20. When the caisson 301 swings or the water flow fluctuates, the retrieval devices are controlled to retract and extend the cable assemblies 20 connected to the corresponding anchor piles 10. By adjusting the tension of the cable assemblies 20, the water flow force borne by the caisson 301 is resisted, ensuring the stability of the caisson 301 under complex water flow conditions.

[0032] In this embodiment, the retrieval device includes a drive unit and an adapter connected via cable assemblies. The drive unit is used to retract and extend the cable assembly 20. The adapter includes a first adapter 401 slidably connected to the support frame 302 and a second adapter 402 slidably connected to the platform 30. Each first adapter 401 and each second adapter 402 operates independently. Each adapter is connected to a separate cable assembly 20, and each cable assembly 20 is connected to a separate anchor pile 10. Each retrieval device is connected to a separate anchor pile 10, and unidirectional adjustment of the caisson 301 is achieved by retracting and extending the corresponding cable device 20. Through the cooperation of multiple anchoring devices, cable assemblies 20, and retrieval devices, the overall adjustment of the caisson 301 is achieved. During the retraction and extension process, each cable assembly 20 operates independently and will not entangle or rub against each other.

[0033] In this embodiment, the platform 30 is also provided with several support frames 302, and the retrieval device includes an adapter connected to the cable assembly 20. The adapter includes a first adapter 401, such as... Figure 4 As shown, the first adapter 401 is slidably mounted on the support frame 302. In this embodiment, the support frame 302 is provided with a plurality of first slide rails 303, and the bottom of the first adapter 401 is provided with a first roller adapted to the first slide rail 303. Through the cooperation of the first roller and the first slide rail 303, the first adapter 401 can move along the first slide rail 303 to ensure that the cable assembly 20 will not twist during the winding process.

[0034] In this embodiment, the retrieval device further includes a second adapter 402, which is slidably connected to the platform 30. The platform 30 is provided with several second slides 304, and the support frame 302 has channels through which the second slides 304 can pass. The bottom of the second adapter 402 is provided with a second roller adapted to the second slide 304. Through the cooperation of the second roller and the second slide 304, the second adapter 402 can move along the second slide 304. In this embodiment, the horizontal height of the second slide 303 is lower than the horizontal height of the first slide 304. The layered arrangement of the first slide 303 and the second slide 304 enables efficient use of space and is more conducive to the simultaneous retrieval and deployment of multiple cable assemblies 20. The first slide rail 303 is not parallel to the second slide rail 304, and the height of the second adapter 402 is lower than the height difference between the first slide rail 303 and the second slide rail 304, so that each first adapter 401 and each second adapter 402 can work independently to achieve adjustment in different directions. Specifically, this embodiment includes two first slide rails 303 and four second slide rails 304, and the length direction of each first slide rail 303 is perpendicular to the length direction of each second slide rail 304.

[0035] In this embodiment, each of the first slide rails 303 and the second slide rails 304 is welded from two 20a channel steels, and a protrusion is formed at the position where it contacts the adapter. The protrusion fits snugly against the bottom of the adapter. The bottom of the adapter is provided with a hook that matches the protrusion. The protrusions of the first slide rails 303 and the second slide rails 304 are engaged in the hook of the adapter, ensuring that the first adapter 401 and the second adapter 402 will not detach from the first slide rail 303 or the second slide rail 304 during sliding. The support frame 302 is welded from No. 10 channel steel and is fixed to the platform 30 by welding. The first slide rail 303 is welded to the support frame 302, and the second slide rail 304 is fixed to the platform 30 by a clamping plate, which can ensure that the installation of the second slide rail 304 is firm and reliable, and at the same time, it can realize the quick installation and removal of the second slide rail 304.

[0036] In this embodiment, the cable assembly 20 includes a first cable 201 and a second cable 202. One end of the adapter is connected to the first cable 201, and the other end is connected to the second cable 202. In this embodiment, one end of the adapter is provided with an anchor, through which the adapter is connected to the second cable 202, which is a steel strand. The other end of the adapter is provided with a wire rope knot 403, through which the adapter is connected to the first cable 201. In this embodiment, the adapter is welded from several steel plates with thicknesses of 60mm, 40mm, 30mm, 12mm, and 10mm.

[0037] In this embodiment, the retrieval device includes a drive unit, which is connected to the adapter via the cable assembly 20, and can adjust the tension and length of the cable assembly 20. The drive unit includes a jack 404 and a winch, which is connected to the jack 404 via the cable assembly 20, together completing the length adjustment of the cable assembly 20 and the positioning of the caisson 301. The anchoring device also includes a cable guide (not shown in the figure), which is located on the platform 30 near the edge of the anchor pile 10 and connected to the anchor pile 10 via the cable assembly 20. By changing the direction of the cable assembly 20 or restricting its lead-out position, the direct friction between the cable assembly 20 and the platform 30 can be reduced, thereby extending the service life of the cable assembly 20.
