Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a cantilevered unloading platform. Background Technology

[0002] In typical concrete structure construction, traditional unloading platforms require steel sections to extend into the floor for anchoring at the rear end. This not only hinders the cleaning of indoor construction waste but also affects the movement of construction workers. Furthermore, the height difference between the platform and the floor causes inconvenience to the construction process.

[0003] Existing technologies have replaced traditional unloading platforms with cantilevered unloading platforms. Buildings placed on these platforms often require vertical lifting by hoisting machinery. To ensure lifting stability, construction workers typically need to set up lifting points on the building before lifting, which is time-consuming, labor-intensive, and results in low lifting efficiency. This is especially true for irregularly shaped buildings, where a significant amount of time is spent setting up the lifting points.

[0004] In other words, existing technologies that place buildings to be lifted within cantilevered unloading platforms suffer from low lifting efficiency. Summary of the Invention

[0005] This invention provides a cantilevered unloading platform to solve the problem of low lifting efficiency of buildings placed on the cantilevered unloading platform.

[0006] This invention provides a cantilevered unloading platform, comprising:

[0007] A lifting frame, used to hold the building to be lifted; and

[0008] A first inclined cable-stayed device, one end of which is connected to the lifting frame, and the other end of which is connected to the first concrete floor slab; and

[0009] A hoisting device, which is mounted on a lifting frame, is used to hoist the lifting frame; and a fixing frame, which is fixed to a second concrete floor slab, and the fixing frame is detachably connected to the lifting frame.

[0010] The second concrete floor slab is located below the first concrete floor slab. The cantilever unloading platform is constructed such that when the lifting frame is lifted by the hoisting device, the lifting frame is disconnected from the fixed frame.

[0011] In one implementation, the fixed frame includes:

[0012] A first fixed beam, extending along a first direction, is disposed on a second concrete floor slab; and

[0013] A second fixed beam, extending along a first direction and disposed on a second concrete floor slab, is spaced apart from the first fixed beam in the second direction; and

[0014] Multiple first fixing components are used to fix the first fixing beam and the second fixing beam to the second concrete floor slab;

[0015] The first fixed beam and the second fixed beam are detachably connected at one end to the lifting frame. When the lifting device lifts the lifting frame, the lifting frame is disconnected from one end of the first fixed beam and the second fixed beam.

[0016] In one embodiment, the first fixing component includes:

[0017] The first U-shaped embedded part has its opening facing upwards. Part of the first U-shaped embedded part is embedded within the second concrete floor slab, and one end of the second concrete floor slab is provided with external threads; and

[0018] The first pressure plate is inserted through the end of the first U-shaped embedded part that protrudes from the second concrete floor slab; and

[0019] The first locking nut is screwed onto the end of the first U-shaped embedded part that protrudes from the second concrete floor slab;

[0020] When the first locking nut is tightened on the first pressure plate, the first pressure plate presses and fixes the first fixed beam or the second fixed beam onto the second concrete floor slab.

[0021] In one embodiment, the lifting frame includes:

[0022] The first lifting beam extends along a first direction and is installed on the second concrete floor slab, with one end of the first lifting beam abutting against one end of the first fixed beam; and

[0023] The second lifting beam extends along the first direction and is installed on the second concrete floor slab. The second lifting beam is spaced apart from the first lifting beam in the second direction, and one end of the second lifting beam abuts against one end of the second fixed beam.

[0024] The frame, which is fixed to the first and second lifting beams, is used to hold the building to be lifted.

[0025] The cantilevered unloading platform also includes a second fixing component, which is respectively located at the abutment of the first lifting beam and the first fixed beam, and at the abutment of the second lifting beam and the second fixed beam. The second fixing component can fix the abutment of the first lifting beam and the first fixed beam to the second concrete floor slab, and fix the abutment of the second lifting beam and the second fixed beam to the second concrete floor slab.

[0026] In one embodiment, the abutment points of the first lifting beam and the first fixed beam are flush, and the abutment points of the second lifting beam and the second fixed beam are flush. The second fixing component includes:

[0027] The second U-shaped embedded part has its opening facing upwards. Part of the second U-shaped embedded part is embedded within the second concrete floor slab, and one end of the second concrete floor slab is provided with external threads; and

[0028] The second pressure plate is inserted through the end of the second U-shaped embedded part that protrudes from the second concrete floor slab; and

[0029] The second locking nut is screwed onto the end of the second U-shaped embedded part that protrudes from the second concrete floor slab;

[0030] When the second locking nut is tightened on the second pressure plate, the second pressure plate presses and fixes the abutment of the first lifting beam and the first fixed beam onto the second concrete floor slab, or presses and fixes the abutment of the second lifting beam and the second fixed beam onto the second concrete floor slab.

[0031] In one embodiment, the frame includes:

[0032] The base, which is fixed to the first and second lifting beams; and

[0033] Side frames are respectively set on both sides of the base along the second direction;

[0034] An opening frame is provided at the end of the base away from the second concrete floor slab;

[0035] The frame has an opening, and a protective chain is installed at the opening.

[0036] In one embodiment, the frame also includes a protective mesh detachably mounted on the opening frame for sealing the opening.

[0037] In one embodiment, the hoisting device includes:

[0038] Two first lifting rings, spaced apart along a first direction, are positioned on a first lifting beam; and

[0039] Two second lifting rings are spaced apart on the second lifting beam along a first direction, with each of the two second lifting rings corresponding to one of the two first lifting rings; and

[0040] The first lifting chain has one end fixed to one of the two first lifting rings, and the other end fixed to the other first lifting ring; and

[0041] The second lifting chain has one end fixed to one of the two second lifting rings, and the other end fixed to the other second lifting ring.

[0042] In one embodiment, the first cable-stayed device includes:

[0043] The first inclined tie ring is mounted on the first lifting beam; and

[0044] The second inclined tie ring is installed on the second lifting beam, and the second inclined tie ring is installed correspondingly to the first inclined tie ring; and

[0045] A first inclined zipper, one end of which is fixed to a first concrete floor slab, and the other end of which is fixed to a first inclined pull ring; and

[0046] The second diagonal zipper has one end fixed to the first concrete floor slab and the other end fixed to the second diagonal ring.

[0047] In one embodiment, a second inclined cable device is also included, one end of which is connected to the lifting frame, and the other end of which is connected to a third concrete floor slab, which is located above the first concrete floor slab.

[0048] Compared with the prior art, the advantages of this invention are that the fixed frame and the lifting frame are detachably connected, allowing the lifting device to lift both the lifting frame and the building placed within it as a whole. This eliminates the need to lift the building separately, thus eliminating the need to arrange lifting points on the building and improving the convenience and efficiency of lifting. Furthermore, the method of lifting the entire lifting frame in this application is applicable to the lifting of irregular buildings, thereby expanding the applicability of the cantilevered unloading platform.

[0055] The invention will now be further described with reference to the accompanying drawings.

[0056] like Figure 1 As shown, the present invention provides a cantilevered unloading platform, which includes a lifting frame, a first inclined cable tie, a hoisting device, and a fixed frame. The lifting frame is used to hold the building to be lifted; one end of the first inclined cable tie is connected to the lifting frame, and the other end is connected to a first concrete floor slab 100; the hoisting device 30 is mounted on the lifting frame and used to lift the lifting frame; the fixed frame is fixed to a second concrete floor slab 200, and the fixed frame is detachably connected to the lifting frame; the second concrete floor slab 200 is located below the first concrete floor slab 100, and the cantilevered unloading platform is configured such that when the hoisting device 30 lifts the lifting frame, the lifting frame is disconnected from the fixed frame.

[0057] In the above configuration, the fixed frame and the lifting frame are detachably connected, allowing the lifting device 30 to lift both the lifting frame and the building placed within it as a whole. This eliminates the need to lift the building separately, thus avoiding the need to set up lifting points on the building and improving the convenience and efficiency of lifting. Furthermore, the method of lifting the entire lifting frame in this application is applicable to the lifting of irregular buildings, thereby expanding the applicability of the cantilevered unloading platform.

[0058] It should be noted that lifting machinery, such as tower cranes, can achieve vertical lifting of the frame and building by connecting to the lifting device 30 and raising the lifting device 30. The lifting device 30 ensures that the lifting machinery can lift the frame vertically. This improves the stability and reliability of the lifting process.

[0059] It should be noted that the first inclined support device has an inclined support function, which can tighten the lifting frame and prevent the weight of the lifting frame and the building to be lifted from being fully applied to the detachable connection between the fixed frame and the lifting frame. This improves the stability and reliability of the cantilevered unloading platform.

[0060] Specifically, such as Figure 1 As shown, in one embodiment, the fixed frame includes a first fixed beam 41, a second fixed beam 42, and a plurality of first fixed components 43. The first fixed beam 41 extends along a first direction and is disposed on the second concrete floor slab 200; the second fixed beam 42 extends along the first direction and is disposed on the second concrete floor slab 200, with the second fixed beam 42 and the first fixed beam 41 spaced apart in a second direction; the plurality of first fixed components 43 are used to fix the first fixed beam 41 and the second fixed beam 42 to the second concrete floor slab 200; one end of the first fixed beam 41 and the second fixed beam 42 is detachably connected to the lifting frame, and when the lifting device 30 lifts the lifting frame, the lifting frame is disconnected from one end of the first fixed beam 41 and the second fixed beam 42.

[0061] Specifically, such as Figure 2 As shown, in one embodiment, the first fixing component 43 includes a first U-shaped embedded part 431, a first pressure plate 432, and a first locking nut. The first U-shaped embedded part 431 has its opening facing upwards and is partially embedded within the second concrete floor slab 200, one end of which is provided with external threads. The first pressure plate 432 passes through the end of the first U-shaped embedded part 431 that protrudes from the second concrete floor slab 200. The first locking nut is screwed onto the protruding end of the first U-shaped embedded part 431. When the first locking nut is tightened onto the first pressure plate 432, the first pressure plate 432 presses and fixes the first fixing beam 41 or the second fixing beam 42 onto the second concrete floor slab 200.

[0062] Specifically, such as Figure 1As shown, in one embodiment, the lifting frame includes a first lifting beam 11, a second lifting beam 12, and a frame 13. The first lifting beam 11 extends along a first direction and is disposed on the second concrete floor slab 200, with one end abutting against one end of a first fixed beam 41. The second lifting beam 12 extends along the first direction and is disposed on the second concrete floor slab 200, spaced apart from the first lifting beam 11 in a second direction, with one end abutting against one end of a second fixed beam 42. The frame 13 is fixed to the first lifting beam 11 and the second lifting beam 12. 13 is used to place the building to be lifted; the cantilever unloading platform also includes a second fixing component 50, which is respectively set at the abutment of the first lifting beam 11 and the first fixing beam 41, and at the abutment of the second lifting beam 12 and the second fixing beam 42. The second fixing component 50 can fix the abutment of the first lifting beam 11 and the first fixing beam 41 to the second concrete floor slab 200, and fix the abutment of the second lifting beam 12 and the second fixing beam 42 to the second concrete floor slab 200.

[0063] Specifically, such as Figure 1 As shown, in one embodiment, the abutment of the first lifting beam 11 with the first fixed beam 41 is flush, and the abutment of the second lifting beam 12 with the second fixed beam 42 is flush.

[0064] Specifically, such as Figure 1 As shown, in one embodiment, the first and second lifting beams, as well as the first and second fixing beams, are all made of the same type of I-beam.

[0065] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the second fixing component 50 includes a second U-shaped embedded part 51, a second pressure plate 52, and a second locking nut. The second U-shaped embedded part 51 has its opening facing upwards and is partially embedded within the second concrete floor slab 200, one end of which is provided with external threads. The second pressure plate 52 passes through the end of the second U-shaped embedded part 51 that protrudes from the second concrete floor slab 200. The second locking nut is screwed onto the end of the second U-shaped embedded part 51 that protrudes from the second concrete floor slab 200. When the second locking nut is tightened onto the second pressure plate 52, the second pressure plate 52 presses and fixes the abutment of the first lifting beam 11 and the first fixing beam 41 onto the second concrete floor slab 200, or presses and fixes the abutment of the second lifting beam 12 and the second fixing beam 42 onto the second concrete floor slab 200.

[0066] Specifically, such as Figure 1As shown, in one embodiment, the frame 13 includes a base 131, side frames 132, and an opening frame 133. The base 131 is fixed to the first lifting beam 11 and the second lifting beam 12; the side frames 132 are respectively disposed on both sides of the base 131 along a second direction; the opening frame 133 is disposed on the end of the base 131 away from the second concrete floor slab 200; the opening frame 133 has an opening, and a protective chain 135 is provided at the opening.

[0067] It should be noted that the building can be inserted into the frame 13 through the opening, and the protective chain 135 is used to prevent the building and people from falling out of the opening.

[0068] Specifically, such as Figure 1 As shown, in one embodiment, the frame 13 further includes a protective net 134, which is detachably disposed on the opening frame 133 for sealing the opening.

[0069] It should be noted that the protective net 134 is used to prevent the building from falling out of the opening during hoisting.

[0070] Specifically, such as Figure 1 As shown, in one embodiment, the opening is trapezoidal. Of course, it can also be set to other shapes depending on the actual situation.

[0071] Specifically, such as Figure 1 As shown, in one embodiment, the lifting device 30 includes two first lifting rings 31, two second lifting rings 32, a first lifting chain 33, and a second lifting chain 34. The two first lifting rings 31 are spaced apart along a first direction on the first lifting beam 11; the two second lifting rings 32 are spaced apart along the first direction on the second lifting beam 12, with each second lifting ring 32 corresponding to one of the two first lifting rings 31; one end of the first lifting chain 33 is fixed to one of the two first lifting rings 31, and the other end of the first lifting chain 33 is fixed to the other first lifting ring 31; one end of the second lifting chain 34 is fixed to one of the two second lifting rings 32, and the other end of the second lifting chain 34 is fixed to the other second lifting ring 32.

[0072] Specifically, such as Figure 1As shown, in one embodiment, the first inclined pull device includes a first inclined pull ring 21, a second inclined pull ring 22, a first inclined pull chain 23, and a second inclined pull chain 24. The first inclined pull ring 21 is mounted on the first lifting beam 11; the second inclined pull ring 22 is mounted on the second lifting beam 12, corresponding to the first inclined pull ring 21; one end of the first inclined pull chain 23 is fixed to the first concrete floor slab 100, and the other end of the first inclined pull chain 23 is fixed to the first inclined pull ring 21; one end of the second inclined pull chain 24 is fixed to the first concrete floor slab 100, and the other end of the second inclined pull chain 24 is fixed to the second inclined pull ring 22.

[0073] Specifically, such as Figure 1 As shown, in one embodiment, a second inclined cable device 60 is also included, one end of which is connected to the lifting frame, and the other end of the second inclined cable device 60 is connected to a third concrete floor slab 300, which is located above the first concrete floor slab 100.

[0074] It should be noted that the second cable-stayed device 60 has the same structure and function as the first cable-stayed device, and will not be described in detail here.

[0075] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention.
