Description

Technical Field

[0001] This invention relates to the field of prestressed wire winding construction technology for circular water tanks, specifically to an anti-skid mechanism for a wire winding wheel and a prestressed wire winding construction device. Background Technology

[0002] Circular water tanks are widely used in various fields such as water conservancy, municipal engineering, and industry, including clear water tanks in waterworks, sedimentation tanks in sewage treatment plants, and cooling water tanks in power plants. They offer advantages such as reasonable structural stress distribution, small footprint, and stable water flow, enabling efficient water storage and treatment. In the construction of circular water tanks, wire-wound prestressed construction is a key technology. By applying prestress to the tank walls, it effectively counteracts the circumferential tensile force borne by the walls during water storage, thereby significantly improving the tank's crack resistance and load-bearing capacity, extending its service life, and ensuring safe operation. Compared to ordinary reinforced concrete water tanks, tanks using wire-wound prestressed technology can withstand greater water pressure with the same material usage, or reduce material usage for the same load-bearing requirements, thus lowering construction costs.

[0003] In the early days, the prestressing construction of circular water tanks was mostly carried out manually. This method was not only labor-intensive and inefficient, but also difficult to guarantee the uniformity of the wire winding and the accuracy of the prestressing application, which could easily lead to uneven stress on the tank wall and affect the quality and performance of the water tank. At present, some simple mechanical wire winding equipment has emerged, which can replace manual wire winding and realize the mechanized construction of wire winding for circular water tanks. During construction, a wire winding wheel with wire wound on it needs to be continuously used to supply wire. Since the winding surface of the wire winding wheel is a cylindrical surface and its height is much larger than the diameter of the wire, the wire cocoon wound on it will inevitably move back and forth at both ends of the winding surface. Therefore, the wire on the winding wheel is prone to jumping when it exits, which can easily cause safety accidents during construction. Summary of the Invention

[0012] Optionally, the outer diameter of the rotating cylinder is smaller than the diameter of the slot, so as to form an insert ring between the outer wall of the rotating cylinder and the inner wall of the slot. The depth of the insert ring matches the thickness of the baffles at both ends of the winding wheel, and the outer diameter of the insert ring matches the outer diameter of the baffles at both ends of the winding wheel.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0028] Please refer to Figures 1 to 6 This invention provides an anti-skid mechanism for a winding wheel, comprising: a fixed frame 10, wherein a damping block 20 is slidably disposed in the fixed frame 10 in the vertical direction, and the damping block 20 has a horizontally opened wire slide 21, the line of which the wire slide 21 is tangent to the winding surface of the winding wheel, and the wire slide 21 is used to pass through the end of the wire wound by the winding wheel; when the damping block 20 slides to the highest position, the height of the wire slide 21 is level with the highest point of the winding surface of the winding wheel; when the damping block 20 slides to the lowest position, the height of the wire slide 21 is level with the lowest point of the winding surface of the winding wheel.

[0029] The anti-skid mechanism for the winding wheel provided in this embodiment includes a fixed frame 10 with a vertically slidable buffer block 20 on it. A horizontal wire slide 21 is provided on the buffer block 20. When the winding wheel feeds wire, the wire end passes through the wire slide 21 and is supplied to the winding device. During the wire feeding process, the buffer block 20 slides up and down with the wire, using its own gravity to generate sliding resistance, thereby preventing the wire from suddenly jumping up and effectively improving the stability of the winding wheel during wire feeding, thus solving the problem of wire skipping. Furthermore, by setting the wire slide 21 to be tangent to the winding surface, the smoothness of wire feeding during the winding wheel is effectively improved. In addition, by limiting the lifting range of the buffer block 20, excessive movement is prevented. Through the cooperation of the above features, the anti-skid mechanism for the winding wheel can effectively solve the problem of wire jumping when the winding wheel feeds wire.

[0030] To further explain the specific structure of the fixing frame 10, the fixing frame 10 is vertically provided with a pair of sliding rods 11, and the two sides of the buffer block 20 are respectively slidably connected to the two sliding rods 11, so that the wire slide 21 is located between the two sliding rods 11.

[0031] The above settings prevent the buffer block 20 from swinging unnecessarily, allowing it to slide only in the vertical direction. At the same time, the wire slide 21 is positioned between the two slide rods 11, improving the force balance of the buffer block 20.

[0032] In order to further extend the limiting support distance of the wire slide 21 for the wire, the fixing frame 10 is provided with a connecting arm 12 protruding along the direction of the wire slide 21. The connecting arm 12 extends away from the winding wheel. The outer end of the connecting arm 12 is provided with a guide cylinder 13. The guide cylinder 13 is coaxially arranged with the wire slide 21.

[0033] To further reduce frictional loss of the steel wire during the wire feeding process, a pair of first clamping rollers 211 are provided inside the steel wire slide 21. The two first clamping rollers 211 are coplanar and rotatably connected to the inner wall of the steel wire slide 21, respectively. The distance between the two first clamping rollers 211 matches the diameter of the steel wire. A pair of second clamping rollers 131 are provided at the inner end of the guide cylinder 13. The two second clamping rollers 131 are coplanar and rotatably connected to the connecting arm 12, respectively. The distance between the two second clamping rollers 131 matches the diameter of the steel wire. The rolling directions of the first clamping rollers 211 and the second clamping rollers 131 are parallel to the extension direction of the steel wire slide 21. The first clamping rollers 211 and the second clamping rollers 131 are arranged perpendicularly.

[0034] It should be noted that the inlet end faces of both the wire guide 21 and the guide cylinder 13 are ground into arc surfaces to further reduce wire wear.

[0035] In order to provide structural support for the winding wheel and to provide a base for the fixing frame 10 so that the wire slide 21 is always tangent to the wheel surface of the winding wheel, the above-mentioned anti-skid mechanism for the winding wheel also includes a rotating seat 30, which is used to be coaxially rotatably connected to one end of the winding wheel; the fixing frame 10 is fixedly connected to the rotating seat 30.

[0036] To further explain the specific structure of the rotating seat 30, a cylindrical slot 31 is opened at the top of the rotating seat 30. A limiting ring groove 32 is coaxially carved on the side wall of the bottom of the slot 31. A first ball ring groove 311 is coaxially carved on the bottom of the slot 31. A second ball ring groove 321 is coaxially carved on the outer wall of the limiting ring groove 32. Both the first ball ring groove 311 and the second ball ring groove 321 are uniformly filled with a plurality of balls 33. A rotating cylinder 34 is coaxially rotatably inserted into the slot 31. The side wall of the bottom end of the rotating cylinder 34 extends radially outward to form a limiting edge 341. The limiting edge 341 matches the limiting ring groove 32. The rotating cylinder 34 is used to be coaxially inserted into the end of the winding wheel.

[0037] The above settings effectively improve the smoothness of the rotating drum 34 and provide a structural basis for the installation of the winding wheel.

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

[0039] Please refer to Figures 1 to 6 This embodiment also provides a wire-wound prestressed construction device, comprising: a wire-wound device 1, which is used to wind steel wire around the side wall of a circular pool; a second device including a wire-wound wheel 2, which is used to wind steel wire 3 and provide steel wire 3 to the wire-wound device 1; and a third device including any of the above-mentioned anti-skid mechanism for the wire-wound wheel, wherein the straight line of the steel wire slide 21 is tangent to the wire-wound surface of the wire-wound wheel 2, and when the anti-skid block 20 slides to the highest position, the height of the steel wire slide 21 is flush with the highest point of the wire-wound surface of the wire-wound wheel 2; and when the anti-skid block 20 slides to the lowest position, the height of the steel wire slide 21 is flush with the lowest point of the wire-wound surface of the wire-wound wheel 2.

[0040] It should be noted that the above-mentioned wire winding device 1 can be any of the existing wire winding devices for circular water tanks.

[0041] To further enhance the automation and convenience of the device, the axis of the winding wheel 2 is vertically set, and a moving carriage 4 is rotatably connected to the bottom of the winding wheel 2. The moving carriage 4 is used to move in a circle around the outer side of the circular pool, and the fixed frame 10 is fixedly connected to the moving carriage 4.

[0042] In order to further improve the density of the steel wire arrangement during the winding process of the winding device 1 and avoid the steel wire swaying, the bottom of the winding device 1 is vertically connected to the winding rod 5, and the winding rod 5 is slidably connected to the winding head 6, which is used to slide and sleeve with the steel wire 3.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
