Description

Technical Field

[0001] This utility model relates to the technical field of circular silo slipform equipment, specifically a circular silo slipform lifting device. Background Technology

[0002] Slipform construction is a continuous concrete pouring process that uses a hydraulic system to simultaneously lift the formwork, enabling the continuous forming of vertical structures such as silos and chimneys. During high-altitude operations of slipform construction for circular silos, the load distribution is uneven due to wind. At a wind speed of 10 m / s, the lateral wind pressure on a 30 m high platform is approximately 0.6 kN / m², which may generate an overturning moment of several hundred Newtons, causing the platform to shift. This significantly increases the risk of the pouring platform tilting inward, and makes it difficult to adjust the levelness of the formwork during concrete pouring. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a circular silo slipform lifting device that can solve the problems of wind load displacement and structural swaying in high-altitude slipform construction.

One end of each first connecting rod is connected to the annular mounting plate through a hinge, and the other end of each first connecting rod is hinged to the side of the first bracket.

[0007] Furthermore, the multiple slings provided at the bottom of the top plate are arranged in a circular array, with the top ends of the slings fixedly connected to the top plate and the bottom ends of the slings fixedly connected to the annular bottom plate.

[0008] Furthermore, both the top plate and the annular bottom plate have through holes, and a threaded rod is provided in the through hole. A fastening nut that is threadedly engaged with the threaded rod is fitted on the threaded rod.

[0009] Furthermore, a protective railing is provided on the outside of the horizontal operating platform. The protective railing includes posts and a protective net.

[0017] Example 1

[0018] like Figures 1 to 2As shown, a circular silo slipform lifting device includes a support rod 6, a hydraulic lifter 5 that works with the support rod 6, a lifting frame 1 fixedly connected to the hydraulic lifter 5, and a horizontal operating platform 2 fixedly connected to the lifting frame 1. A ring foundation is poured, and the support rod 6 is pre-embedded. The hydraulic lifter 5 climbs along the support rod 6, causing the lifting frame 1 to move upwards as a whole. Two arc-shaped templates 4 are fixedly connected to the lifting frame 1, located on the inner and outer sides of the circular silo. Reinforcing bars are pre-tied between the two arc-shaped templates 4, and concrete is poured. The concrete solidifies to form a cylindrical silo. The process of lifting, tying, pouring, and solidifying is repeated. The solid-state cyclic operation forms a cylindrical silo of a certain height. The horizontal operating platform 2, located at a higher position, needs to withstand the influence of wind to prevent it from shifting inwards. Therefore, a suspension assembly 7 is designed. This suspension assembly 7 also reduces wind resistance. Specifically, the suspension assembly 7 includes an annular mounting plate 71, several first connecting rods 72, a first bracket 74, a support rod 73, a top plate 77, several slings 79, and an annular base plate 78. The bottom of the annular mounting plate 71 is fixedly connected to the lifting frame 1, and the several first connecting rods 72 are arranged in a circular array on the annular mounting plate 71. This embodiment uses a specific configuration... Taking the three first connecting rods 72 as an example, the three first connecting rods 72 are distributed in a triangular pyramid shape to ensure that the first bracket 74 will not be biased towards any one of the connecting rods. One end of the first connecting rod 72 is connected to the annular mounting plate 71 through a hinge, and the other end of the first connecting rod 72 is hinged to the side of the first bracket 74. The support rod 73 is inserted into the first bracket 74, and the support rod 73 and the first bracket 74 are connected as one piece by welding. The top plate 77 is fixedly connected to the bottom of the support rod 73. Multiple slings 79 are arranged in a circular array at the bottom of the top plate 77. Both the top plate 77 and the annular bottom plate 78 have openings. A threaded rod 10 is inserted through the through hole, and a fastening nut 11 with threaded engagement is fitted on the threaded rod 10. A threaded rod 10 is installed at each end of the sling 79. A fastening nut 11 is installed at the end of the upper and lower threaded rods 10 that passes through the corresponding through hole, thereby connecting the annular bottom plate 78 and the top plate 77 into one unit through the sling 79. By turning the fastening nut 11 located below the annular bottom plate 78, the threaded rod 10 is rotated, thereby pushing the support point upward and finally raising the inner side of the suspended horizontal operating platform 2, thereby preventing the pouring platform (horizontal operating platform 2) from tilting inward due to wind pressure.

[0019] like Figure 1 As shown, each side of the horizontal operating platform 2 is equipped with a guardrail 8. The guardrail 8 includes several posts and a safety net. Multiple posts are arranged in a circular pattern on the horizontal operating platform 2, and are fixedly connected to the platform. The safety net is also fixed to each post, thereby reducing the risk of workers falling from the edge of the horizontal operating platform 2. Figure 2As shown, the support rod 73 is equipped with a second bracket 75, which is located below the first bracket 74. The second bracket 75 is welded to the support rod 73. A limiting rod 76 is hinged to the second bracket 75. A sleeve 12 is fitted onto the first connecting rod 72, and the sleeve 12 is fixedly connected to the first connecting rod 72. The other end of the limiting rod 76 is hinged to the side of the sleeve 12. The limiting rod 76 supports the support rod 73 and limits its own sway, thus improving overall stability. Figure 1 As shown, a diagonal brace 3 is fixedly connected to the bottom of the horizontal operating platform 2, and the other end of the diagonal brace 3 is fixedly connected to the lifting frame 1. The diagonal brace 3 can support the horizontal operating platform 2 on the lifting frame 1, thereby further ensuring the force balance of the horizontal operating platform 2.

[0020] In summary, this silo slipform lifting device improves construction safety and stability by providing multi-point support to the horizontal operating platform 2 through suspension components. This device solves the problems of wind load displacement and structural swaying during high-altitude slipform construction, enhancing overall safety and stability. It is suitable for slipform construction of large-diameter silos. The following three points can be summarized:

[0021] First, the wind-resistant and anti-deviation design features a suspension assembly consisting of a triangular pyramid-shaped hinged first connecting rod 72 and a support rod 73, combined with an adjustable sling 79, threaded rod 10, and fastening nut 11 to form a dynamic balance system. By adjusting the fastening nut 11, the inward tilt angle of the horizontal operating platform 2 can be corrected in real time, effectively counteracting the inward deviation caused by wind pressure and ensuring the stability of high-altitude operations.

[0022] Secondly, the multi-level reinforcement structure, the second bracket 75 and the limiting rod 76 form an auxiliary support system, which restricts the swaying of the support rod 73 and enhances the overall rigidity of the suspension assembly. The horizontal operating platform 2 and the lifting frame 1 are added with diagonal bracing to distribute the load and improve the platform's resistance to lateral forces, further ensuring the balance of forces.

[0023] Third, safety protection is optimized. The circular distribution of guardrails 8 combined with the safety net effectively prevents personnel or materials from falling and reduces the risk of working at height. The modular design of the suspension components, such as the detachable circular base plate 78 and top plate 77, facilitates installation and maintenance, while reducing wind resistance and adapting to the high-altitude environment.
