Description

Technical Field

[0001] This utility model relates to the field of lifting frames, specifically to a high-pier lifting frame. Background Technology

[0002] During the construction of high piers, the lifting frame is usually used as a formwork support. The formwork and the end of the lifting frame are connected by tie rods to provide support. The verticality of the lifting frame is usually ensured by controlling the synchronous lifting of the support rods with through-hole jacks. However, the accuracy of synchronous lifting cannot be fully guaranteed. Vertical adjustment can only be made by jacks after lifting. It is impossible to completely return the lifting frame to the initial horizontal position, so the lifting frame cannot be accurately adjusted.

[0003] like Figure 1 , Figure 2 As shown, the inventor developed a grid-shaped lifting frame with controllable verticality, with publication number CN117569217A and patent name "A Lifting Frame with Controllable Verticality". By setting an adjustment part on the through-type jack and setting telescopic parts on the adjacent sides of the adjustment part, the posture of the lifting frame can be adjusted by the telescopic parts.

[0004] However, during the adjustment process, since the contact surface between the lifting frame and the adjustment part is a plane, when the lifting frame and the adjustment part tilt relative to each other, the plane cannot adapt to the change in tilt angle, resulting in a smaller contact surface, increased pressure, increased wear on the lifting frame and the adjustment part, making the adjustment unsmooth, thereby reducing the adjustment accuracy and increasing construction errors. Therefore, a structure is needed that can adapt to the change in tilt angle during the adjustment process. Utility Model Content

[0005] The present invention aims to provide a high-pier lifting frame that can adapt to changes in tilt angle during the adjustment process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pier lifting frame, comprising several support units, wherein in the horizontal direction, the several support units are perpendicular to each other to form a grid structure and form four nodes, and a vertical guide hole is formed at each node;

[0007] Each node is also equipped with a support rod, a through-hole jack, and two telescopic components. The through-hole jack has an adjustment part, which is supported below the support unit. The lower end of the support rod is embedded in the cast-in-place section of the pier column. The upper end of the support rod passes through the through-hole jack, the adjustment part, and the guide hole in sequence. The lower end of each telescopic component is hinged to the adjustment part; the upper end of each telescopic component is hinged to the support unit.

[0008] Several support units include two upper support units and two lower support units. At each node, the upper support unit supports the lower support unit above it. The lower support unit is provided with a first connecting part and a second connecting part on its lower side. The lower support unit passes through the first connecting part and the second connecting part. A steel block is provided between the second connecting part and the first connecting part. The steel block is positioned between the lower support unit and the adjusting part. The lower surface of the steel block includes a first arc surface. The upper surface of the adjusting part is a second arc surface. The first arc surface is supported on the second arc surface.

[0009] The beneficial effects of this plan are:

[0010] 1. By setting a first arc surface and a second arc surface, regardless of the tilt angle of the lifting frame relative to the adjusting part, the first arc surface on the lower surface of the lifting frame and the second arc surface on the adjusting part always maintain a partial contact. This prevents the contact area between the lifting frame and the adjusting part from decreasing after adjustment, ensuring pressure stability and avoiding deformation of the adjusting part. This adapts to changes in tilt angle during the adjustment process.

[0011] 2. Compared with the existing technology where the upper surface of the adjustment part is flat, in this solution, when adjusting the lifting frame, the first arc surface and the second arc surface slide relative to each other, making the adjustment more stable and smooth.

[0012] 3. In this scheme, the upper and lower support units are staggered vertically to avoid disconnecting the support unit in one direction, thus ensuring the integrity of the support unit and optimizing the stress structure.

[0013] Furthermore, the telescopic component includes an upper telescopic component and a lower telescopic component. The upper end of the output shaft of the upper telescopic component is hinged to the first connecting part, and the upper end of the output shaft of the lower telescopic component is hinged to the lower support unit. The lower ends of the upper and lower telescopic components are at the same height on adjacent sides of the adjustment part, and the distance between the upper ends of the upper and lower telescopic components and the adjustment part is equal.

[0014] Furthermore, the radius of the second arc surface is smaller than that of the first arc surface.

[0015] Furthermore, the adjustment part is a shell, and a support frame is provided inside the adjustment part. The support frame includes an annular disk, and a support rod passes through the center of the annular disk. The annular disk is circumferentially connected to the inner side of the adjustment part. Several upper support plates are provided circumferentially on the upper side of the annular disk. All upper support plates are vertically arranged. The upper side of the upper support plate is supported by a second arc surface. A plumb bob is set on the inward side of the upper support plate. Several lower support plates are provided circumferentially on the lower side of the annular disk. All lower support plates are vertical right-angled triangular plates. One side of the lower support plate is connected to the inner side of the adjustment part.

[0016] Furthermore, the second connecting part and the first connecting part are symmetrically arranged on both sides of the lower support unit, and the first connecting part is perpendicular to the lower support unit and at the same height.

[0017] Furthermore, the lower support unit includes two parallel lower channel steels, the upper support unit includes two parallel upper channel steels, the first connecting part includes two parallel connecting channel steels, the lower flange of the upper channel steel and the upper flange of the connecting channel steel are bolted together, the upper channel steel and the lower channel steel are perpendicular to each other on the horizontal plane, the connecting channel steel and the lower channel steel are at the same height, and one end of the connecting channel steel abuts against the lower channel steel.

[0018] This solution also has the following effects:

[0019] 1. This design involves setting the steel profiles in two layers, one above the other. Therefore, the expansion joints in both directions also need to be set at different heights to accommodate the height of the steel profiles. However, this will result in uneven stress on both sides of the adjustment section during the adjustment process.

[0020] If the upper telescopic component and the upper support unit are directly connected, and the lower ends of the upper and lower telescopic components are at the same height on adjacent sides of the adjustment part, and the distance between the upper ends of the upper and lower telescopic components and the adjustment part is equal (it is necessary to ensure that the stress positions of the upper and lower support units are both optimal stress positions), then the tilt angles of the upper and lower telescopic components will inevitably be different. This will result in the upper telescopic component transmitting a larger vertical force to the adjustment part, while the lower telescopic component transmitting a larger horizontal force to the adjustment part, leading to an imbalance of forces on the adjustment part and deformation.

[0021] In this solution, by setting a connecting part, the height of the upper end of the telescopic component is reduced, so that the upper and lower telescopic components are symmetrically arranged relative to the adjustment part. This not only allows the posture of the frame to be raised at any time, but also ensures the durability of the adjustment part and the stability of the overall structure.

[0022] 2. Since the lifting frame does not necessarily rotate around the center of the second arc surface, the radius of the second arc surface needs to be smaller than that of the first arc surface to ensure smooth adjustment.

[0023] 3. To reduce costs and facilitate observation of the verticality of the support rod, the adjustment part in the prior art patent adopts a shell structure with the shell side vertically arranged. However, this also means that the adjustment part can only provide good vertical support. When the above shell structure is applied to this solution, when the lifting frame is tilted relative to the adjustment part, the lifting frame generates an eccentric force on the adjustment part, which can easily damage the top of the adjustment part.

[0024] Therefore, in this solution, a support frame is installed inside the adjustment section to support the second arc surface at the top of the adjustment section. The eccentric load is gradually converted into a vertical load through the upper support plate and the lower support plate, and finally transferred to the side wall of the adjustment section, thereby enhancing the stability of the overall structure.
