[0001] The present application relates to the field of civil engineering technology, and in particular to a chain-falling mechanism for a hydraulically lifting formwork structure. Background Art

[0002] In the construction industry, with the increasing number of high-rise, multi-story, and large, complex buildings, formwork construction has become a critical step in the construction process. The hydraulic formwork lifting device utilizes hydraulic technology to automatically raise and lower the formwork, significantly improving construction efficiency and reducing labor intensity.

[0003] During the hydraulic lifting process, after the object is lifted to the specified position, it needs to be kept in a stable hover; at this time, people set a fall chain on the climbing frame equipped with a hydraulic lifting formwork device. At this time, the fall chain can play a locking role, causing the placed object to slide down in the vertical direction, ensuring safety during the construction process.

[0004] However, during the process of lifting the formwork with the falling chain, the formwork may shake due to external factors such as wind, causing harm to nearby workers, which needs to be improved. Utility Model Content

[0012] By adopting the above technical solution, when connecting the rigid rod and the connecting plate, the slot of the rigid rod is sleeved on the outer wall of the connecting plate, and the movable slot and the plug-in slot are arranged opposite each other. At this time, the plug-in block is plugged into the plug-in slot under the elastic force of the spring, reducing the situation where the connecting plate is separated from the slot, and the connection between the connecting plate and the rigid rod is completed.

[0013] Optionally, the connecting plate is provided with a guide block, and the inner wall of the plug-in slot is provided with a guide groove for plugging the guide block.

[0014] By adopting the above-mentioned technical solution, the cooperation between the guide block and the guide groove can increase the contact area between the connecting plate and the rigid rod, thereby improving the stability of the connection between the connecting plate and the rigid rod; and the cooperation between the guide and the guide groove has a guiding effect, so that the movable groove and the plug-in groove are set opposite to each other.

[0015] Optionally, the guide ring is provided with a threaded hole, and a bolt for abutting against the outer wall of the guide rod is installed in the threaded hole.

[0016] By adopting the above technical solution, when the connection between the connecting plate and the rigid rod is cancelled, bolts are used to abut against the outer wall of the guide rod, which can reduce the free sliding of the rigid rod on the guide rod and facilitate the reconnection of the rigid rod and the connecting plate.

[0017] Optionally, a rubber sheet is provided between the bolt and the guide rod.

[0018] By adopting the above technical solution and arranging the rubber sheet, the bolt can be flexibly connected to the outer wall of the guide rod, which can increase the stability of the guide ring fixed to the outer wall of the guide rod and reduce the damage to the guide rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1.

[0025] 2. By detachably connecting the rigid rod and the connecting plate, after the template of the hook is lifted to the specified position, the plug-in fit between the plug-in block and the plug-in slot is cancelled, so that the connecting plate can be disengaged from the plug-in slot, so as to facilitate the assembly of the template.

The mounting plate 1 is slidably installed on the bottom plate of a climbing frame 8, and the lifting component 2 and the guide rod 5 are both installed on the mounting plate 1; the climbing frame 8 is installed with a cylinder, which is used to drive the mounting plate 1 to slide on the climbing frame 8; by sliding the mounting plate 1 to the bottom of the climbing frame 8, the position of the hook 4 can be changed according to the installation position of the formwork, thereby improving the practicality of the structure.

[0035] Reference Figure 2 The guide rod 5 includes a plurality of support rods 51 connected in sequence. The support rod 51 at the head end is fixed to the bottom of the mounting plate 1. A threaded rod 52 is welded to one end of the support rod 51, and a threaded groove 53 is provided at one end of the adjacent support rod 51 to cooperate with the threaded rod 52. The cooperation between the threaded rod 52 and the threaded groove 53 can realize the detachable connection of the two adjacent support rods 51, and the number of support rods 51 can be increased or decreased according to the height of the climbing frame 8.

[0036] Reference Figure 3 A guide ring 6 is sleeved on the outer wall of the support rod 51, and a threaded hole 61 is opened on the outer wall of the guide ring 6. A bolt 62 for abutting against the outer wall of the support rod 51 is installed in the inner thread of the threaded hole 61. In this embodiment, a rubber sheet 63 is provided at one end of the bolt 62 close to the support rod 51; when it is necessary to fix the guide ring 6 to the support rod 51, the bolt 62 is rotated toward one side of the support rod 51, so that the end of the bolt 62 with the rubber sheet 63 can be tightly abutted against the outer wall of the support rod 51, thereby reducing the free sliding of the guide ring 6 on the outer wall of the support rod 51.

[0037] Reference Figure 1 and Figure 4 One end of the chain 3 is connected to the lifting assembly 2, and the other end of the chain 3 is installed with a connecting plate 41, which is connected to the hook 4. The lifting assembly 2 is used to drive the hook 4 to move up and down; a rigid rod 7 is fixed to the outer wall of the guide ring 6, and a connecting part 71 is integrally formed at one end of the rigid rod 7, and the connecting part 71 is detachably connected to the connecting plate 41; by canceling the connection between the hook 4 and the rigid rod 7, the template that has been moved to the specified position can be installed.
