Description

Technical Field

[0001] This utility model relates to the field of rotating construction technology, and in particular to a safety support foot for rotating construction. Background Technology

[0002] Bridges constructed using the rotation method involve building the bridge section spanning a river, highway, or railway on both banks or along the roadside. The superstructure is completed at the construction site, and then the beams on both banks or along the roadside are rotated to the working site and joined together to form the entire bridge. Bridge rotation technology transforms work above obstacles into work on the bank or near the ground, ensuring construction safety, minimizing traffic disruption, reducing closure time, and lowering construction costs. With the rapid development of transportation construction projects in recent years, more and more new bridge projects intersect with existing highways, railways, and rivers. Given the high safety and minimal traffic impact of the rotation method, it is currently the most common construction method for new overpass bridges.

[0003] Common bridge rotation devices mainly consist of a slide rail, support legs, and a central ball joint or rotation bearing. The support legs act as safety legs to support the stability of the rotating structure during rotation. They provide safety support during the rotation process, effectively preventing excessive lateral tilting of the superstructure and avoiding overturning. A gap is left between the support legs and the top surface of the slide rail for pre-rotation weighing tests and post-rotation posture adjustments. However, during rotation, the gap between the support legs and the slide rail leaves the support legs suspended in the air. Therefore, wind loads or other adverse loads during rotation can cause the rotating structure to tilt to one side, affecting the safety and stability of the rotation system. Thus, effectively eliminating the gap between the support legs and the slide rail during rotation is a crucial problem that needs to be solved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety support foot for rotating construction, which solves the problem that the gap between the support foot and the slide rail affects the smooth rotation of the rotating structure during rotating operations.

[0005] According to an embodiment of the present invention, a safety support foot for rotating construction includes a ship plate, an upper connecting plate, and a locking assembly. The top of the ship plate is symmetrically provided with a lower cylinder, and the top of the lower cylinder is horizontally supported by a lower connecting plate. The upper connecting plate is positioned above the lower connecting plate by a limiting assembly, which is used to adjust the distance between the lower connecting plate and the upper connecting plate. The top of the upper connecting plate is symmetrically provided with an upper cylinder. There are several locking assemblies, which are used to lock the upper connecting plate and the lower connecting plate.

[0006] Compared with the prior art, this utility model has the following beneficial effects: by setting a limiting component between the lower connecting plate and the upper connecting plate, the limiting component adjusts the distance between the upper connecting plate and the lower connecting plate, and the upper connecting plate and the lower connecting plate are locked and fixed by the locking component, thereby changing the gap between the boat plate and the slide at the bottom of the lower cylinder. This allows workers to increase or decrease the gap between the boat plate and the slide according to different needs, which facilitates the weighing test of the rotating structure or allows the boat to contact the slide so that the device can support the rotating structure, achieving the safety and stability of the rotating structure during the rotation process.

[0007] Furthermore, the adjustment component includes a first wedge block and a second wedge block, the inclined surfaces of the first wedge block and the second wedge block are adapted to each other, and the first wedge block and the second wedge block are wedge-shaped and positioned between the upper connecting plate and the lower connecting plate.

[0008] Furthermore, each locking assembly includes a bolt and a nut, and the upper and lower connecting plates are provided with several through holes for the bolt to pass through.

[0009] Furthermore, it also includes a limiting block, which is movably positioned between the upper connecting plate and the lower connecting plate.

[0010] Furthermore, the limiting block includes a first support block and a second support block. A screw is fixedly provided on the top of the first support block, and the second support block is threadedly connected to the screw.

[0011] Furthermore, a waist plate is fixedly fitted between the two upper cylinders.

[0012] Furthermore, a vertical plate is fixed between the two lower cylinders.

[0013] Furthermore, several reinforcing plates are provided between the ship plate and the lower cylinder. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a safety support foot for rotating construction, including a ship plate 1, an upper connecting plate 4, and locking components. A lower cylinder 2 is symmetrically arranged on the top of the ship plate 1, and a lower connecting plate 3 is horizontally mounted on the top of the lower cylinder 2. The upper connecting plate 4 is positioned above the lower connecting plate 3 by a limiting component, which is used to adjust the distance between the lower connecting plate 3 and the upper connecting plate 4. An upper cylinder 5 is symmetrically arranged on the top of the upper connecting plate 4. Several locking components are provided to lock the upper connecting plate 4 and the lower connecting plate 3 together. Concrete or sand is injected into the lower and upper cylinders to improve their strength. In this embodiment, the ship plate 1 can be arc-shaped and is set above the slide rail on the top of the lower support platform. The upper cylinder 5 is pre-embedded in the upper support platform. To facilitate the implementation of the rotation and weighing test, after the device is installed, the upper connecting plate 4 and the lower connecting plate 3 are released by the locking assembly. Then, the distance between the upper connecting plate 4 and the lower connecting plate 3 is changed by the limiting assembly so that the gap between the ship plate 1 and the slide rail meets the design requirements. Then, the upper connecting plate 4 and the lower connecting plate 3 are locked and fixed by the locking assembly. After the rotation structure weighing test is completed and before the rotation operation is performed, the upper connecting plate 4 and the lower connecting plate 3 are locked and fixed by the locking assembly. After the connecting plate 3 is released, the limiting assembly is adjusted again so that the boat plate 1 contacts the top of the slide. Specifically, the boat plate 1 contacts the PTFE sliding plate at the top of the slide. Then, the locking assembly is adjusted again to lock and fix the upper connecting plate 4 and the lower connecting plate 3. This ensures that during subsequent rotation operations, the device adjusts the distance between the upper connecting plate 4 and the lower connecting plate 3 through the limiting assembly and locking assembly, thereby changing the gap between the boat plate 1 and the slide. This facilitates the weighing test of the rotating structure and also provides safety support for the rotating structure during rotation operations, making the rotation of the structure more stable. During the rotation process, the safety support foot eliminates the gap between the support foot and the slide by adjusting the first wedge plate and the second wedge block 7. This changes the existing rotating structure, which only has a single point of force on the ball joint during rotation operations, to a multi-point force-bearing structure, ensuring the safety, smoothness, and stability of the rotating system during rotation.

[0020] like Figure 1-3As shown, the adjustment component further includes a first wedge block 6 and a second wedge block 7. The inclined surfaces of the first wedge block 6 and the second wedge block 7 are adapted to each other. After the first wedge block 6 and the second wedge block 7 are wedge-shaped and fitted together, they are disposed between the upper connecting plate 4 and the lower connecting plate 3. In this embodiment, a first wedge block 6 and a second wedge block 7 are provided at both ends of the cavity between the upper connecting plate 4 and the lower connecting plate 3. The horizontal surface of the first wedge block 6 is in close contact with the bottom of the upper connecting plate 4, and the horizontal surface of the second wedge block 7 is in close contact with the top of the lower connecting plate 3. The inclined surfaces of the first wedge block 6 and the second wedge block 7 are in close contact. By sliding the first wedge block 6 and the second wedge block 7 relative to each other, the height formed after the wedge-shaped engagement of the first wedge block 6 and the second wedge block 7 is changed. This height is the distance between the upper connecting plate 4 and the lower connecting plate 3. Finally, the upper connecting plate 4 and the lower connecting plate 3 are locked and fixed by the locking assembly. According to different operational requirements, the engagement height between the first wedge block 6 and the second wedge block 7 can be changed by releasing the locking assembly. Preferably, the inclined surfaces of the first wedge block 6 and the second wedge block 7 are roughened to increase friction.

[0021] like Figure 2-3 As shown, each locking assembly further includes a bolt 8 and a nut 9. The upper connecting plate 4 and the lower connecting plate 3 each have several through holes for the bolt 8 to pass through. After the distance between the upper connecting plate 4 and the lower connecting plate 3 is initially limited by the first wedge block 6 and the second wedge block 7, the bolt 8 is passed through the lower connecting plate 3 and the upper connecting plate 4 sequentially from bottom to top, and then locked in place by the nut 9, thereby further fixing the distance between the upper connecting plate 4 and the lower connecting plate 3. Preferably, in this embodiment, the first wedge block 6 and the second wedge block 7 are also provided with multiple through holes for the bolts 8 to pass through. When the bolts 8 pass through the upper connecting plate 4 and the lower connecting plate 3, the bolts 8 also pass through the through holes on the first wedge block 6 and the second wedge block 7. This further ensures that the first wedge block 6 and the second wedge block 7 do not move when the safety support foot is subjected to vertical pressure. On the other hand, through holes can be opened at specific positions of the first wedge block 6 and the second wedge block 7 through pre-calculation. When the different through holes of the first wedge block 6 and the second wedge block 7 are aligned, the distance between the upper connecting plate 4 and the lower connecting plate 3 is at a specific distance, so that the gap between the boat plate 1 and the slide is convenient for weighing tests or rotating operations.

[0022] like Figure 1-3As shown, further, a limiting block 10 is also included, which is movably disposed between the upper connecting plate 4 and the lower connecting plate 3. The height of the limiting block 10 is the same as the distance between the upper connecting plate 4 and the lower connecting plate 3. After adjusting the distance between the upper connecting plate 4 and the lower connecting plate 3, the limiting block 10 is placed between the upper connecting plate 4 and the lower connecting plate 3, so that the limiting block 10 supports the upper connecting plate 4 and the lower connecting plate 3 under vertical force, thereby further ensuring that the first wedge block 6 and the second wedge block 7 do not move when the device is subjected to vertical pressure.

[0023] like Figure 2-3 As shown, the limiting block 10 further includes a first support block 101 and a second support block 102. A screw 103 is fixedly provided on the top of the first support block 101, and the second support block 102 is threadedly connected to the screw 103. To facilitate flexible adjustment of the support height of the limiting block 10, the operator can adjust the support height of the limiting block 10 by rotating the second limiting block 10, causing the screw 103 to screw into or out of the second limiting block 10.

[0024] like Figure 1-3 As shown, a waist plate 11 is further fixedly sleeved between the two upper cylinders 5. Specifically, the waist plate 11 is located at the middle position of the outer circumference of the upper cylinder 5, and the waist plate 11 is welded and fixed to the two upper cylinders 5 respectively, thereby improving the connection strength between the two upper cylinders 5.

[0025] like Figure 1-3 As shown, furthermore, a vertical plate 12 is fixedly provided between the two lower cylinders 2. In this embodiment, there are two vertical plates 12, both of which are disposed between the outer walls of the two lower cylinders 2, with one end of each vertical plate 12 fixedly connected to the ship plate 1, and the other end of each vertical plate 12 fixedly connected to the bottom of the lower connecting plate 3. The vertical plate 12 improves the connection strength between the two lower cylinders 2 and between the ship plate 1 and the lower connecting plate 3.

[0026] like Figure 1-3 As shown, furthermore, a number of reinforcing plates 13 are provided between the ship plate 1 and the lower cylinder 2. One end of the reinforcing plate 13 is fixedly connected to the ship plate 1 and the other end is fixedly connected to the outer wall of the lower cylinder 2, thereby improving the connection strength between the lower cylinder 2 and the ship plate 1.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
