Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a floor hoisting device. Background Art

[0002] High-rise building construction requires a variety of materials. Relying on manual transport would greatly increase the burden on workers. Therefore, materials used in high-rise building construction are mostly transported by cranes. Existing cranes are divided into two types according to their usage scenarios: those working outside buildings and those working inside buildings. Cranes working outside buildings require the installation of an unloading platform, which poses certain safety hazards. Cranes working inside buildings usually have a cantilever. To prevent the crane from tipping forward, a counterweight can be added to the crane, and the gravity generated by the counterweight can be used to balance the gravity of the cantilever. However, the handling of the counterweight will still increase the labor intensity of the workers. Alternatively, the crane and the lower floor slab can be fixed with expansion bolts to prevent the crane from tipping forward. However, when the crane transports items, it will exert a large force on the lower floor slab, which may damage the structure of the lower floor slab. Utility Model Content

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] The utility model provides a floor hoisting device, which is used for protecting floor slabs and avoiding damage to the floor slab structure, while reducing the labor intensity of workers and improving construction efficiency.

[0033] like Figures 1 to 4 As shown, the floor includes an upper floor 200 and a lower floor 100, and the floor hoisting device includes a support assembly 1 and a hoisting assembly 2. The support assembly 1 includes a support frame 11 and a lifting member 12. The lifting member 12 is located at the bottom end of the support frame 11 and can be fixedly connected to the lower floor 100. The lifting member 12 can drive the support frame 11 to move in the vertical direction so that the top of the support frame 11 abuts against the upper floor 200; the hoisting assembly 2 includes a cantilever beam 21 and a hoisting trolley 22. The cantilever beam 21 extends in the horizontal direction, and the cantilever beam 21 is fixedly connected to the support frame 11. The hoisting trolley 22 is movably connected to the cantilever beam 21. The hoisting trolley 22 can move from outside the building to inside the building along the cantilever beam 21.

[0034] When in use, the lifting member 12 is fixedly connected to the lower floor 100, and the support frame 11 is connected to the lifting member 12. The lifting member 12 drives the support frame 11 to move in the vertical direction so that the top of the support frame 11 abuts against the upper floor 200, and then the support frame 11 is clamped between the upper floor 200 and the lifting member 12, so that the support frame 11 will not fall over. Relying on the upper floor 200 and the lower floor 100 to clamp the support assembly 1 can prevent the support frame 11 from damaging the lower floor 100; when the lifting member 12 descends, the support frame 11 and the upper floor 200 are disengaged, making it easy to disassemble. In the process of lifting materials, the lifting trolley 22 can be filled with materials, and then moved from outside the building to inside the building along the cantilever beam 21 to unload materials inside the building, reducing the labor intensity of workers.

[0035] The support frame 11 can be an integrally formed frame structure or a support structure formed by assembling, as long as it can play a supporting role. In this embodiment, the support frame 11 adopts an assembled structure, which is convenient for carrying to the corresponding floor and reduces labor intensity.

[0036] Specifically, the support frame 11 includes at least two first support members 111 spaced apart along the first direction. The top of the first support member 111 can abut against the upper floor 200. The bottom of the first support member 111 is connected to the lifting member 12. At least two first support members 111 are connected to the cantilever beam 21. Two adjacent first support members 111 are connected by a first connecting member 112. The first direction is as follows. Figure 4 The direction indicated by X.

[0037] There can be two, or three or more first support members 111. The first support members 111 are spaced apart along the first direction so that the support assembly 1 has a larger footprint and increased stability. By installing the first connecting member 112, multiple first support members 111 are fixed together. The bottom end of the first support member 111 is connected to the lifting member 12, which drives the first support member 111 to rise in the vertical direction and then press against the upper floor 200, so that the first support member 111 is clamped between the upper floor 200 and the lifting member 12. At least two first support members 111 are connected to the cantilever beam 21 to ensure that the first support member 111 will not overturn.

[0038] The first support member 111 can be plate-shaped or rod-shaped, as long as it can meet the load-bearing capacity. For example, the first support member 111 is rod-shaped to save installation space. The first support member 111 includes at least two support rods 1111 spaced apart along the second direction, the support rods 1111 extend in the vertical direction, and adjacent support rods 1111 are connected by connecting rods 1112. The cantilever beam 21 is connected to the connecting rods 1112, and the first direction is perpendicular to the second direction. The second direction is as shown in FIG. Figure 4 Shown in the Y direction.

[0039] The lower ends of the support rods 1111 are connected to the lifting member 12. Adjacent support rods 1111 are connected and fixed via connecting rods 1112, allowing the support rods 1111 to be sandwiched between the upper floor 200 and the lifting member 12 without tipping over. Furthermore, the connecting rods 1112 provide support for the cantilever beam 21. Specifically, the cantilever beam 21 overlaps at least two connecting rods 1112 along a first direction. The cantilever beam 21 and the connecting rods 1112 can be connected via U-bolts 300, providing a secure and easy connection. Preferably, the cantilever beam 21 is an I-beam, facilitating connection to the connecting rods 1112 via U-bolts 300.

[0040] The connecting rod 1112 can be set horizontally or tilted. As long as the connecting rod 1112 can connect the support rods 1111. The connecting rod 1112 is overlapped with two adjacent support rods 1111, and the connecting rod 1112 and the support rods 1111 can be fixed by welding or binding with steel wire ropes.

[0041] To improve the stability of the first support member 111, a plurality of connecting rods 1112 may be provided. Each first support member 111 includes a plurality of connecting rods 1112 spaced apart in the vertical direction, and the connecting rods 1112 extend along the second direction. This can enhance connection stability, save space, and facilitate installation.

[0042] For example, see Figure 2 and Figure 3 The first support member 111 includes two support rods 1111 spaced apart along the second direction, and three connecting rods 1112 spaced apart along the vertical direction, each connecting rod 1112 being connected to two support rods 1111. The three connecting rods 1112 are provided in the vertical direction so that the cantilever beam 21 can be overlapped with the middle connecting rod 1112 and secured with U-bolts 300. The connecting rods 1112 and support rods 1111 can be secured by welding or by tying with steel wire ropes.

[0043] For each first support member 111, three or more support rods 1111 may be arranged at intervals along the second direction. For example, three support rods 1111 are arranged, and along the second direction, one connecting rod 1112 simultaneously connects the three support rods 1111, or one or more connecting rods 1112 may be arranged between every two adjacent support rods 1111. When one connecting rod 1112 simultaneously connects three support rods 1111, the connecting rod 1112 extends along the second direction and is welded to the three support rods 1111. When one connecting rod 1112 is arranged between every two adjacent support rods 1111, the connecting rod 1112 can be staggered in the vertical direction, and when the connecting rod 1112 fails, it is easy to replace.

[0044] For example, the first support member 111 is plate-shaped. It is a circular frame, the top of which can abut against the upper floor slab 200, and the bottom of which is connected to the lifting member 12. The cantilever beam 21 extends through the circular frame along the first direction. The circular frame is vertically arranged to facilitate clamping between the upper floor slab 200 and the lifting member 12.

[0045] Adjacent circular frames are secured together using first connectors 112 to improve their stability. The first connectors 112 can extend horizontally or at an angle. Multiple first connectors 112 can be spaced apart horizontally and / or spaced apart vertically.

[0046] Preferably, two circular frames are spaced apart along the first direction, and four first connectors 112 are provided. The first connectors 112 extend through the circular frames along the first direction and are positioned at four vertices on the inner side of the circular frames. The first connectors 112 are welded to the circular frames. The cantilever beam 21 extends along the first direction, overlaps the inner sides of the two circular frames, and is secured by U-bolts 300.

[0047] The support frame 11 includes at least two first support members 111. When two first support members 111 are provided, the two first support members 111 are connected by one or more first connecting members 112. Optionally, the first connecting members 112 are welded to the first support members 111. The first connecting members 112 can extend along the first direction or extend at an angle.

[0048] The plurality of first connectors 112 may be spaced apart along the second direction or spaced apart along the vertical direction. Preferably, four first connectors 112 are provided, extending along the first direction, with two first connectors 112 spaced apart along the vertical direction on the same side of the first support member 111, and the remaining two first connectors 112 spaced apart along the vertical direction on the other side of the first support member 111. The first connectors 112 are welded to the first support member 111, providing a secure connection and convenient operation.

[0049] When there are multiple first support members 111, in order to improve the stability after the multiple first support members 111 are connected, multiple first connecting members 112 are arranged between two adjacent first support members 111, and at least two first connecting members 112 are arranged at intervals in the horizontal direction; and / or, at least two first connecting members 112 are arranged at intervals in the vertical direction.

[0050] For example, three or more first support members 111 are arranged at intervals along the first direction. A single first connector 112 may simultaneously connect the three first support members 111, or one or more first connectors 112 may be provided between each two adjacent first support members 111. When a single first connector 112 simultaneously connects the three first support members 111, the first connector 112 extends along the first direction and is welded to the three first support members 111. When one or more first connectors 112 are provided between each two adjacent first support members 111, the first connectors 112 may be staggered in the vertical direction, and replacement of the first connector 112 may be facilitated if a failure occurs.

[0051] First connector 112 can be plate-shaped or rod-shaped, as long as it serves to connect and secure first support member 111. Schematically, first connector 112 is rod-shaped, making it easier to carry and saving installation space. First connector 112 is a connecting beam, which overlaps connecting rod 1112 and is welded to connecting rod 1112. This provides a secure connection and easy operation.

[0052] Exemplarily, two first support members 111 are arranged at intervals along the first direction, four first connecting members 112 are fixedly connected between the two first support members 111, and the first connecting members 112 extend along the first direction, wherein two first connecting members 112 are arranged at intervals along the vertical direction on the same side of the first support member 111, and the remaining two first connecting members 112 are arranged at intervals along the vertical direction on the other side of the first support member 111, and the first connecting members 112 are welded to the first support member 111.

Each first support member 111 includes three connecting rods 1112, and the connecting rods 1112 are welded to the support rods 1111 along the second direction. For ease of description, the middle connecting rod 1112 among the three connecting rods 1112 spaced apart along the vertical direction is the first connecting rod. A cantilever beam 21 is provided on the two first connecting rods. The cantilever beam 21 extends along the first direction and overlaps the middle position of the first connecting rod 1112.
