Problems solved by technology
Due to the constant changes in size and direction of water flow, wind force and waves, the steel wire rope sleeve on the positioning anchor pile is easy to swing from side to side or move up and down. Broken wires, especially when the wire rope sheath moves up and down many times, will change the angle and force of the wire rope and affect the accurate positioning of the main structure

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] see figure 1 and figure 2 As shown, the embodiment of the present invention provides an underwater steel wire rope high-altitude positioning device, which is used in conjunction with a cylindrical positioning anchor pile 1. Supporting plate 3 and ring beam 2, ring beam 2 and ring supporting plate 3 are fixed.
[0028] The top of the annular supporting plate 3 is fixedly provided with at least two fixed blocks 4 along the circumferential direction, the fixed blocks 4 are fixedly connected with the inner side wall of the ring beam 2, and a slide block 5 is arranged between the positioning anchor pile 1 and the fixed block 4; 4 and slide block 5 all comprise bottom surface and mating surface, and the sum of the transverse width of the bottom surface of fixed block 4 and the bottom surface of slide block 5 is greater than the di...

The invention discloses a high-attitude positioning device and method for an underwater steel wire rope and relates to the technical field of bridge construction. The high-attitude positioning device comprises an annular supporting plate and an annular beam which are sequentially arranged from inside to outside along the circumferential direction of a positioning anchor pile, wherein at least two fixing blocks are arranged at the top of the annular supporting plate along the circumferential direction, and sliding blocks are arranged between the positioning anchor pile and the fixing blocks; each of the fixing blocks and the sliding blocks comprises a bottom surface and a fitting surface, the sum of the transverse width of the two bottom surfaces is larger than the distance between the positioning anchor pile and the annular beam, and the two fitting surfaces are in sliding contact; the annular beam is connected with an operating platform at the top of the positioning anchor pile through a first lifting member, and the sliding blocks are connected with the operating platform at the top of the positioning anchor pile through second lifting members; at least two steel wire rope limiting plates are arranged at the bottom of the annular supporting plate along the circumferential direction. The high-attitude positioning device and method for the underwater steel wire rope have the advantages that the accurate positioning of the underwater steel wire rope can be realized at a high attitude, the underwater construction is changed to above-water construction, the risk of underwater construction is reduced, the device can be reused and the economic cost is reduced.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to an underwater wire rope high-altitude positioning device and a positioning method. Background technique [0002] At present, in large-scale water construction, temporary positioning is required for some main structures, but the main structure must overcome the influence of other external factors such as water flow and wind during temporary positioning. Anchor piles, one end of the steel wire rope is arranged with a rope sleeve, the rope sleeve is set on the positioning anchor pile, and the other end is fixed on the main structure. Due to the constant changes in size and direction of water flow, wind force and waves, the steel wire rope sleeve on the positioning anchor pile is easy to swing from side to side or move up and down. Broken wires, especially when the wire rope sheath moves up and down many times, will change the angle and force of the wire rope and affect ...
