Description

Technical Field

[0001] The invention relates to the technical field of prestressed wire winding construction for circular pools, and in particular to a lifting prestressed wire winding construction mechanism and a stable 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] According to actual construction needs, the height of the circular pool is uncertain, and the existing wire winding devices are generally unable to adapt to the changes. In order to meet certain specific needs, it is necessary to implement prestressed wire winding construction on the circular pool with a higher construction height. In order to facilitate operation, the wire winding device is generally close to the ground, resulting in a large height difference between the steel strands used for wire winding construction and the wire winding point. At this time, it is generally necessary to manually prop up the steel strands so that the wire winding ends are in the same plane as the wire winding points as much as possible. This is not only time-consuming and labor-intensive, but also prone to human errors, causing the wire winding trajectory to deviate from the predetermined trajectory, thereby affecting the uniformity of the wire winding.

[0028] In order to further explain the sliding cooperation structure between the lifting seat 22 and the lifting column 20, the lifting column 20 is provided with a slideway 201 along the length direction, and the slideway 201 passes through the two ends of the lifting column 20 along the length direction; the side wall of the lifting column 20 is provided with a sliding hole 202 along the length direction, and the sliding hole 202 passes through the two ends of the lifting column 20 along the length direction, and the sliding hole 202 passes through the side wall of the lifting column 20 along the thickness direction, so that the slideway 201 is connected with the external environment through the sliding hole 202; the lifting seat 22 is slidably arranged in the slideway 201, and the lifting seat 22 is convexly provided with a traction part, which extends out of the sliding hole 202 and slidably cooperates with the sliding hole 202, and the threading hole 221 is opened at the part of the traction part located outside the lifting column 20.

[0038] Through the above arrangement, the central column 5 is used as a reference, and the support tower 3 is radially pulled through the radial frame 4, so as to effectively stabilize the mobile vehicle 1 and completely avoid its overturning.

[0039] It should be noted that the support tower 3 can also be disassembled and adjusted in height so that its height can be adaptively adjusted according to the height of the circular pool. Similarly, the height of the central column 5 can also be adjusted in the same way, or any telescopic structure in the prior art can be used, which will not be repeated here.
