Description

Technical Field

[0001] The invention relates to the field of lifting equipment, and in particular to an auxiliary device for lifting collapsed buildings in pieces. Background Art

[0002] Cleaning up collapsed buildings, whether caused by accidents or explosions, is a major challenge. Collapsed buildings are characterized by their disorganized and scattered structure, making them difficult to remove mechanically. Therefore, manual handling is often used. However, most collapsed buildings are stacked in layers, with their horizontally stable structures. Using appropriate lifting equipment, large amounts of remaining wall material can be removed relatively quickly and at once. Summary of the Invention

[0003] In order to solve the problem of inconvenience and slow cleaning of collapsed buildings, the present invention provides a collapsed building lifting auxiliary device that solves the above problem.

[0004] An auxiliary device for lifting collapsed buildings in pieces, comprising a lifting plate and a lifting net; the lifting plate is a flat or conical frame structure, and is provided with a plurality of connecting pieces on the top and bottom surfaces respectively; the lifting net is a flexible grid structure, and is connected to the connecting pieces provided on the bottom surface of the lifting plate; the bottom surface of the lifting net is provided with a plurality of steel sheets.

[0005] In a preferred embodiment of the auxiliary device for lifting collapsed buildings in pieces provided by the present invention, the lifting plate is a square frame, including a plurality of concentrically arranged square frames and oblique reinforcing ribs connecting all of the square frames along an oblique direction.

[0006] In a preferred embodiment of the collapsed building lifting auxiliary device provided by the present invention, the lifting plate is a conical frame, including a conical frame arranged on the top surface of the square frame, and vertical reinforcing ribs vertically connecting the square frame and the conical frame.

[0007] In a preferred embodiment of the auxiliary device for lifting collapsed buildings in bulk provided by the present invention, the interval between adjacent square frames is less than or equal to 0.5 m.

[0008] In a preferred embodiment of the auxiliary device for lifting collapsed buildings in batches provided by the present invention, a plurality of hooks are arranged at equal intervals near the center of the top surface of the lifting plate, and a plurality of lifting rings are arranged at equal intervals throughout the entire range of the bottom surface.

[0009] In a preferred embodiment of the auxiliary device for lifting collapsed buildings in a block provided by the present invention, the lifting net is a square, flexible grid structure with a length and width larger than the length and width of the lifting plate; and is connected to all of the lifting rings. The maximum spacing between the holes in the lifting net is 0.1m. The lifting net is connected to the lifting rings at the connection points of the grid; the steel sheets are provided at the connection points of the lifting net and the grid. The spacing between adjacent steel sheets is less than or equal to 0.2m. The number of steel sheets is greater than the number of lifting rings.

[0010] The lifting method based on the collapsed building lifting auxiliary device comprises the following steps:

[0011] Step 1: Hang the lifting plate in the collapsed building lifting auxiliary device on the lifting equipment through the hook;

[0012] Step 2: Use the lifting equipment to move the collapsed building lifting auxiliary device as a whole to the wall of the collapsed building where the layer structure is still stable in the horizontal direction;

[0013] Step 3: Manually hold a nail gun and drive nails through the steel plate of the collapsed building lifting auxiliary device and drive them into the components of the collapsed building, so that the nails are connected to the collapsed building lifting auxiliary device;

[0014] Step 4: Use lifting equipment to remove the collapsed building as a whole.

[0015] Compared with the existing technology, the collapsed building lifting auxiliary device provided by the present invention provides a function that can connect messy and scattered collapsed buildings, thereby facilitating the lifting equipment to remove the collapsed buildings as a whole, greatly improving work efficiency.

[0016] In the event of a collapse due to an accident, the number of on-site rescue personnel can be reduced, the rescue efficiency can be improved, and the survival rate of trapped people can be increased. At the same time, the state of the collapsed building and the relative position of the structures can be preserved as much as possible to facilitate later technical investigations.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please also see Figure 1 and Figure 2 , respectively, are a top view and a side view of the collapsed building lifting auxiliary device 1 provided by the present invention in this embodiment. The accompanying drawings are merely schematic and are not drawn strictly to scale.

[0022] The auxiliary device 1 for lifting a collapsed building in a block comprises a lifting plate 2, eight hooks 21, a plurality of lifting rings 22, a lifting net 3 and a plurality of steel sheets 31.

[0023] The lifting disc 2 comprises seven square frames 23 of varying side lengths, each varying in length at 0.5m intervals. All frames 23 are arranged concentrically with their sides parallel to one another. Four oblique reinforcement ribs 24 connect all frames 23 along the four diagonal angles of the frames 23. The two innermost frames 23 are each equipped with a hook 21 at the top of one side, for a total of eight hooks. These hooks 21 are used to connect to lifting equipment.

[0024] At the bottom of all frames 23, a large number of lifting rings 22 are set at intervals of 0.5m. The lifting rings 22 are used to connect with the lifting net 3. The lifting net 3 is a wire mesh, and the lifting rings 22 are fixed to the bottom of the frame 23 after being connected to the lifting net 3.

[0025] The wire ropes in the lifting net 3 are woven into a grid-like structure with a maximum spacing of 0.1m. At the bottom of the lifting net 3, where the wire ropes are woven, a large number of steel sheets 31 are connected. The spacing between adjacent steel sheets 31 is 0.1m.

[0026] When in use, the lifting plate 2 is hung on the lifting equipment through the hook 21. The collapsed building lifting auxiliary device 1 is moved as a whole to the collapsed building by the lifting equipment, where there is still a wall with layered stacking and layer structure with a stable relative position in the horizontal direction.

[0027] Then, a nail gun is manually held to penetrate the steel sheet 31 and drive the nails into the components of the collapsed building, so that the nails are connected to the collapsed building lifting auxiliary device 1. Finally, the collapsed building is removed as a whole by utilizing a lifting device.

[0028] Example 2

[0029] See also Figure 3 , is a side view of the collapsed building lifting auxiliary device 1 provided by the present invention in this embodiment. The difference from embodiment 1 is:

[0030] The overall conical lifting plate 2 has better structural strength and can more stably remove the collapsed building as a whole.
