Description

Technical Field

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

[0002] For the construction of cylindrical structures, the traditional method currently used is slipform construction. Slipform construction: Slipform, also known as sliding curved formwork, is a general term for the construction method of cast-in-place concrete structures that uses slipform jacks, electric hoists, etc., as lifting power to drive the curved formwork (or sliding frame) along the surface of the concrete (or curved formwork) to form the structure.

[0003] Traditional operating platforms use a steel platform with an arc-shaped formwork support system. The problem is that the supports under the operating platform are difficult to erect in one go. They need to be manually reinforced or dismantled after the machine is stopped, which interrupts the continuity of construction. Moreover, during slipform construction, concrete pouring and equipment movement cause dynamic changes in the load on the platform. The fixed diagonal braces are prone to insufficient or redundant support. Insufficient support strength can lead to the risk of sinking, deformation, or even collapse of the platform edges. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a circular silo slipform connection structure that dynamically adjusts the support angle, effectively solving the problem that traditional fixed diagonal braces cannot adapt to load changes, and significantly improving the stability and safety of the operating platform edge.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A circular silo slipform connection structure includes a lifting frame, with an arc-shaped template fixedly connected to each side of the bottom of the lifting frame. A circular silo formed by casting concrete is located between the two arc-shaped templates. An operating platform is horizontally installed on the lifting frame, with one end of the operating platform fixedly connected to the lifting frame and the other end of the operating platform provided with a diagonal bracing assembly. The diagonal bracing assembly includes a support rod, one end of which is rotatably connected to the bottom of the operating platform, and the other end of which is provided with a fixed seat. The fixed seat is fixedly connected to the bottom of the lifting frame, and a groove is provided on the fixed seat for vertical sliding of the end of the support rod. An electric telescopic rod for driving the support rod to move vertically in the groove is fixedly connected to the bottom of the fixed seat.

[0007] Furthermore, a second through groove is provided on each of the opposite side walls of the sliding groove, and a slidable limiting rod is inserted in the second through groove. The middle part of the limiting rod is inserted into the end of the support rod, and both ends of the limiting rod are inserted into the second through groove. A slot is provided on the inner wall of the second through groove to cooperate with the limiting rod.

[0008] Furthermore, a mounting base is provided between the support rod and the operating platform. The mounting base is fixedly connected to the end of the operating platform away from the lifting frame, and the support rod is rotatably connected in the mounting base.

[0009] Furthermore, the fixed base has a through hole, and a fastener is provided in the through hole. The fastener passes through the through hole and is fixedly connected to the lifting frame.

[0010] Furthermore, the lifting frame includes a column module, which includes a first column located outside the cylindrical silo and a second column located inside the cylindrical silo. A crossbeam module is provided between the first column and the second column. The crossbeam module includes a first crossbeam, one end of which is fixedly connected to the first column and the other end of which is fixedly connected to the second column. The first crossbeam is provided with a second crossbeam, one end of which is fixedly connected to the first column and the other end of which is fixedly connected to the second column. An arc-shaped template is fixedly connected to the bottom of both the first column and the second column.

[0011] Furthermore, a hydraulic jack is installed on the second crossbeam, and a support rod that cooperates with the hydraulic jack is provided between the first column and the second column. The bottom of the support rod is vertically inserted into the cylindrical silo formed by pouring concrete between the two arc-shaped templates.

[0012] Furthermore, a fence is fixedly connected to the operating platform, and two fences are provided, one inside and one outside the operating platform.

[0013] The beneficial effects of this utility model are:

[0014] In this application, the angle of the strut can be adjusted by the electric telescopic rod in the diagonal bracing assembly, which can respond to changes in construction load in real time, avoiding the risk of insufficient support or overload. In addition, the diagonal bracing assembly transfers part of the load at the cantilever end of the platform to the bottom of the lifting frame, reducing the platform's deflection deformation. Furthermore, there is no need for manual disassembly or reassembly of the support, and the electric adjustment saves time, making it suitable for the needs of continuous slipform construction.

Detailed Implementation

[0019] Example 1, such as Figures 1 to 3 As shown, a circular silo slipform connection structure comprises a lifting frame, two inner and outer arc-shaped templates 6, an operating platform 5, and a diagonal bracing assembly 8. An arc-shaped template 6 is fixedly connected to each side of the bottom of the lifting frame, with a gap between the two templates. This gap is subsequently filled with a steel reinforcement frame and then filled with concrete, forming a circular silo 9 after the concrete has solidified. An operating platform 5 is horizontally installed on the lifting frame. One end of the operating platform 5 is fixedly connected to the lifting frame, while the end of the operating platform 5 furthest from the connection to the lifting frame lacks support, making it prone to tilting. This causes the operating platform 5 to become unstable, swaying more easily towards the edge, posing a safety hazard during subsequent concrete pouring operations.

[0020] Therefore, to solve the above problems, a diagonal brace assembly 8 is installed at the other end of the operating platform 5. The diagonal brace assembly 8 can then support the operating platform 5 on the lifting frame. The strength of the external support for the operating platform 5 can be adjusted via the diagonal brace assembly 8, thus ensuring better support. The diagonal brace assembly 8 includes a support rod 81, and a mounting base 82 is provided between the support rod 81 and the operating platform 5. The mounting base 82 is fixedly connected to the end of the operating platform 5 away from the lifting frame. The support rod 81 is rotatably connected to the mounting base 82. A fixing base 85 is provided at the other end of the support rod 81. A through hole is provided on the fixing base 85, and a fastener is installed in the through hole. After passing through the through hole, it is fixedly connected to the column of the lifting frame. The fixed base 85 has a sliding groove 83 for the bottom end of the support rod 81 to slide vertically. A second through groove 86 is provided on each of the opposite side walls of the sliding groove 83. A slidable limiting rod 84 is inserted in the second through groove 86. The middle part of the limiting rod 84 is inserted into the end of the support rod 81, and the two ends of the limiting rod 84 are inserted into the second through groove 86. A slot 87 that cooperates with the limiting rod 84 is provided on the inner wall of the second through groove 86. Multiple slots 87 are provided and arranged in a linear array. An electric telescopic rod 88 for driving the support rod 81 to move vertically in the sliding groove 83 is fixedly connected to the bottom of the fixed base 85.

[0021] During operation, the electric telescopic rod 88 is supported by the fixed base 85. The push rod of the electric telescopic rod 88 pushes the support rod 81 to slide along the slide groove 83 in the fixed base 85. The limiting rod 84, which is inserted at the end of the support rod 81, moves in the second through groove 86, limiting the support rod 81 to move up and down only along the second through groove 86. When a suitable height is reached, the limiting rod 84 is engaged in the corresponding slot 87. At this time, the limiting rod 84 is engaged in the slot 87. After the bottom of the support rod 81 is raised to a certain height and fixed in the fixed base 85, the support rod 81 raises the outer perimeter of the operating platform 5 or has a tendency to raise it, which can prevent the outer perimeter of the operating platform 5 from tilting downward and improve the overall safety. Two guardrails 7 are also fixedly connected to the operating platform 5. The two guardrails 7 are located on the inner and outer sides of the operating platform 5, respectively. The inner and outer guardrails 7 together provide a certain safety guarantee for the operator's activities.

[0022] like Figure 1 As shown, the lifting frame includes a column module 3 and a crossbeam module 2. The column module 3 includes a first column 31 located outside the cylindrical silo 9 and a second column 32 located inside the cylindrical silo 9. The crossbeam module 2 is arranged between the first column 31 and the second column 32. The crossbeam module 2 includes a first crossbeam 21 and a second crossbeam 22. One end of the first crossbeam 21 is fixedly connected to the first column 31, and the other end of the first crossbeam 21 is fixedly connected to the second column 32. One end of the second crossbeam 22 is fixedly connected to the first column 31, and the other end of the second crossbeam 22 is fixedly connected to the second column 32. An arc-shaped template 6 is fixedly connected to the bottom of both the first column 31 and the second column 32. The lifting frame rises by relying on the hydraulic jack 4 fixedly connected to the second crossbeam 22, and the support rod 1 that cooperates with the hydraulic jack 4. The hydraulic jack 4 moves upward on the support rod 1 through its operation. The hydraulic jack 4 drives the entire lifting frame connected to it to move up on the support rod 1. The bottom of the support rod 1 is vertically inserted into the cylindrical silo 9 formed by pouring concrete between the two arc-shaped templates 6. After the concrete solidifies, the cylindrical silo 9 is connected to the support rod 1 as a whole. Subsequently, as the height of the cylindrical silo 9 increases, the support rod 1 can be continuously lengthened by welding.

[0023] Working principle:

[0024] Multiple lifting frames are arranged in a circular array on the foundation. Each lifting frame has two arc-shaped templates 6 at its bottom, one inner and one outer. The arc-shaped templates 6 on adjacent lifting frames are spliced ​​together, with multiple inner arc-shaped templates 6 forming an inner ring and multiple outer arc-shaped templates 6 forming an outer ring. The gap between the inner and outer rings forms a groove for pouring concrete. Reinforcing bars are pre-tied into this groove and then concrete is poured in. After solidification, a cylindrical silo 9 is formed. During the sliding process, hydraulic jacks 4 work to drive themselves to move upward on the support rod 1, which in turn moves the entire lifting frame connected to the hydraulic jacks 4 upward on the support rod 1. The sliding, tying, pouring, and solidification processes are repeated sequentially to form a cylindrical silo 9. The cylindrical silo 9 is at a certain height. During this process, it needs to be operated on the operating platform 5. One end of the operating platform 5 is supported on the lifting frame, while the other end of the operating platform 5 is supported by the diagonal bracing assembly 8. The electric telescopic rod 88 in the diagonal bracing assembly 8 is supported by the fixed seat 85. The electric telescopic rod 88 pushes the support rod 81 to slide along the slide groove 83 in the fixed seat 85. The limiting rod 84, which is inserted into the end of the support rod 81, moves in the second through groove 86, limiting the support rod 81 to move up and down only along the second through groove 86. When the appropriate height is reached, the limiting rod 84 is slid into the corresponding slot 87, which can ensure that the operating platform 5 remains stable and improve the overall safety.
