Description

Technical Field

[0001] The present application relates to the technical field of template installation, and in particular to an end mold installation and removal platform and a method for removing the end mold. Background Art

[0002] Traditionally, box girder end formwork installation and disassembly mostly relies on a gantry crane coupled with manual pulling to adjust its position and posture. Domestically, large box girder end formwork installation and removal is typically performed directly by gantry cranes. During the suspension process, a hand hoist or forklift is required to forcibly pull the end formwork to adjust its position and posture, resisting the resistance of the steel cage or the adhesion of the concrete to ensure that the end formwork fits the outer formwork. This approach can easily damage the end formwork and the box girder structure. Therefore, an installation trolley is used during the installation and removal of the end formwork.

[0003] At present, the patent document with authorization announcement number CN218985178U discloses an automatic end mold installation and removal platform, which includes an end mold and a bracket. The end mold is provided with an end mold upper connecting seat and an end mold lower connecting seat. The bracket is provided with an end mold upper limiting mechanism matched with the end mold upper connecting seat and an end mold lower limiting mechanism matched with the end mold lower connecting seat. The bracket is also provided with an upper telescopic mechanism and a lower telescopic mechanism for realizing end mold demoulding or mold closing. The upper telescopic mechanism is connected to the outer mold, and the lower telescopic mechanism is connected to the box beam outer mold or the box beam bottom mold. The installation and removal platform of the present application realizes the connection between the end mold and the bracket through the end mold upper limiting mechanism and the end mold lower limiting mechanism. The end mold upper limiting mechanism and the end mold lower limiting mechanism have position self-adjustment performance and adaptability, which effectively improves the efficiency of end mold installation and removal.

[0060] S3: The lifting seat 52 then moves vertically and drives the end mold 4 to move horizontally via the receiving roller 61 so that the end mold 4 is aligned with the installation position of the box beam. Subsequently, the mounting plate 12 drives the receiving roller 61 downward. At the same time, the lifting seat 52 moves upward to align the end mold 4 with the box beam again. Subsequently, the fixing plate 71 abuts against the side wall of the end mold 4 to fix the end mold 4. The base 1 then drives the end mold 4 close to the box beam. The rodless cylinder 9 then drives the end mold 4 against the box beam. Finally, the end mold 4 and the box beam are fixedly connected by bolts.

[0061] S4: The fixed plate 71 returns to its original position, and the base 1 drives the fixed bracket 2 to retreat;
