Description

Technical Field

[0001] The invention relates to the technical field of prestressed wire winding construction for a circular pool, and in particular to an anti-wire jump mechanism for a wire winding wheel and a prestressed wire winding construction device. Background Art

[0002] Circular pools are widely used in water conservancy, municipal administration, industry and other fields, such as clear water pools in water plants, sedimentation tanks in sewage treatment plants, cooling water pools in power plants, etc. They have the advantages of reasonable structural force, small footprint, stable water flow state, etc., and can efficiently realize functions such as water storage and water treatment. In the construction of circular pools, wire prestressing construction is a key technology. By applying prestress to the pool wall, it can effectively offset the circumferential tension on the pool wall during the water storage process, thereby greatly improving the pool's crack resistance and bearing capacity, extending its service life, and ensuring safe operation. Compared with ordinary reinforced concrete pools, pools using wire prestressing technology can withstand greater water pressure with the same amount of material, or reduce material usage under the same load requirements, thereby reducing construction costs.

[0003] In the early days, the prestressed wire winding construction of circular pools mostly adopted manual wire winding. This method is not only labor-intensive and has low construction efficiency, but also difficult to ensure the uniformity of wire winding and the accuracy of prestressing, which can easily lead to uneven force on the pool wall and affect the quality and performance of the pool. At present, some simple mechanical wire winding equipment has appeared, which can replace manual mechanical wire winding, thereby realizing the mechanized construction of circular pool wire winding. During its construction, it is necessary to continuously use a wire winding wheel with steel wire to supply steel wire. Since the winding surface of the wire winding wheel is a cylindrical surface, and the height is much larger than the diameter of the steel wire, the steel wire cocoon wound thereon will inevitably move back and forth at both ends of the winding surface. Therefore, the steel wire of the wire winding wheel is prone to jumping when it is wired out, which is easy to cause safety accidents during construction. Summary of the invention

[0037] Through the above arrangement, the smoothness of the rotation of the drum 34 is effectively improved, and a structural basis is provided for the installation of the winding wheel.

[0038] In order to further optimize the structure, make the winding wheel more stable after installation, and make the lowest position of the slow jump block 20 more reasonable, so as to avoid the thickness of the limit plate at the bottom of the winding wheel affecting the slow jump block 20, the outer diameter of the rotating cylinder 34 is smaller than the diameter of the slot 31, so as to form an embedded ring 35 between the outer wall of the rotating cylinder 34 and the inner wall of the slot 31, and the depth of the embedded ring 35 matches the thickness of the baffles at both ends of the winding wheel, and the outer diameter of the embedded ring 35 matches the outer diameter of the baffles at both ends of the winding wheel.
