Description

Technical Field

[0001] This utility model belongs to the field of steel formwork hoisting technology, specifically relating to a hoisting device for large steel formwork used in deep foundation pit sidewalls. Background Technology

[0002] Large steel formwork is widely used in subway side wall construction due to its ease of installation and dismantling, simple construction, and high safety. Currently, tower cranes are commonly used for hoisting large steel formwork. However, given the large volume and small gaps in the internal support beams of multi-layered reinforced concrete structures in deep foundation pits, the vertical hoisting and subsequent installation of large steel formwork remains a technical challenge. Furthermore, support dismantling can only commence after all corresponding horizontal layers of the structure have been formed and reached their design strength, which can easily cause delays. To solve the installation problem after vertical hoisting of large steel formwork, a new hoisting device needs to be developed to improve the installation accuracy and efficiency, and shorten the construction period.

[0003] The existing technology has the following problems:

[0004] 1. Currently available hoisting devices on the market do not have perfect functionality when used by users, which affects the user's ability to use the hoisting devices.

[0005] 2. Currently available hoisting devices require users to use auxiliary tools when using them for hoisting and limiting, which increases the user's operating costs. Utility Model Content

[0012] Using the above technical solution, the hook that connects the hoisting rope and the electric hoist makes it easy for the user to connect the hoisting rope and the hook.

[0013] This utility model further illustrates that a traction rope is installed on the side surface of the shelf, and there are multiple traction ropes.

[0014] The above technical solution, which includes multiple traction ropes, facilitates the user's handling and traction of items.

[0015] This utility model further illustrates that the nut is connected between a fixing block and a limiting snap-fit ​​plate, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0016] The above technical solution, which uses a fixing block symmetrically arranged with the vertical center line of the nut as the axis of symmetry, facilitates the user's use and positioning of the nut.

[0034] In this embodiment, a traction rope 7 is installed on the side surface of the shelf 6, and there are multiple traction ropes 7. The multiple traction ropes 7 make it convenient for the user to use and process the items by pulling. The nut 10 is connected to the fixing block 13 and the limiting snap plate 12. The fixing block 13 is symmetrically arranged with the vertical center line of the nut 10 as the axis of symmetry. The fixing block 13 symmetrically arranged with the vertical center line of the nut 10 as the axis of symmetry makes it convenient for the user to use and limit the installation of the nut 10.

[0035] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an electric hoist 3 is installed on the bottom surface of the I-beam rail 1, a hoisting rope 4 is installed on the bottom surface of the electric hoist 3, and a shelf 6 is installed on the bottom surface of the I-beam rail 1.
