[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The present invention provides the following embodiments:

[0042] Embodiment 1:

[0043] like Figure 1-Figure 11 As shown, a hoisting device for prefabricated wall panels of green buildings comprises two longitudinal beams 1 and a cross beam 6 connected between the two longitudinal beams 1. Two support members 4 are symmetrically installed at the bottom of the two longitudinal beams 1, and lifting rings 2 are fixed on both sides of the top of the two longitudinal beams 1. The four support members 4 are used to support the prefabricated wall panels.

[0044] The cross beam 6 is telescopically adjustable, and includes a cross beam plate 61 having a cavity inside, and two movable plates 63 slidably arranged in the cavity, one end of each of the two movable plates 63 is fixed with a connecting plate 62, and one of the connecting plates 62 is fixedly connected to one of the longitudinal beams 1, and the other connecting plate 62 is fixedly connected to the other longitudinal beam 1, and the two movable plates 63 are commonly connected to an adjustment structure 7 that drives their relative movement.

[0045] Specifically, regarding the above-mentioned adjustment structure 7, as Figure 9-11 As shown, the adjustment structure 7 includes a rotating rod 72 rotatably installed in the cavity, a driving gear 73 is installed on the rotating rod 72, and the top end of the rotating rod 72 extends to the outside of the crossbeam plate 61 and is installed with an adjusting hand wheel 71, and the two movable plates 63 are provided with a rack 74 meshing with the driving gear 73 on the opposite sides.

[0046] Through the above, when the green building prefabricated wall panels are hoisted, the hoisting device can be connected to the external crane as a whole through the hoisting ring 2, and then the green building prefabricated wall panels are supported by four support members 4, so as to place the green building prefabricated wall panels on the hoisting device, and then the hoisting device is hoisted by the external crane, and then the hoisting device hoists the green building prefabricated wall panels until the green building prefabricated wall panels are hoisted to the installation height, so as to facilitate the assembly and installation of the green building prefabricated wall panels;

[0047] In the process of hoisting the prefabricated green building wall panels, the hoisting device can be adjusted along the length direction according to the specifications of the prefabricated green building wall panels, and the specific adjustment steps are as follows:

[0048] The rotating rod 72 is rotated by adjusting the hand wheel 71, so that the rotating rod 72 drives the driving gear 73 to rotate, and then the driving gear 73 drives the two movable plates 63 to move relative to each other through the rack 74 meshing with it, so that the two longitudinal beams 1 are separated from each other (such as Figure 2 As shown), the lifting device can be adjusted along its length direction, so that the lifting device can adapt to green building prefabricated wall panels of different specifications, thereby facilitating the lifting of green building prefabricated wall panels of different specifications.

[0049] Furthermore, in order to ensure the stable movement of the movable plate 63, as Fig.10 and Fig.11 As shown, guide strips 65 are fixed on both sides of the inner wall of the cavity, and guide grooves 64 matching with the guide strips 65 are formed on the opposite sides of the two movable plates 63 .

[0050] Furthermore, if Figure 1-Figure 3 as well as Figure 7 and Figure 8 As shown, two retractable reinforcing rods 3 are connected between the two longitudinal beams 1, and the two reinforcing rods 3 are symmetrically distributed on both sides of the cross beam 6. Each reinforcing rod 3 includes a first rod body 31 fixed on the inner side of one of the longitudinal beams 1, and a second rod body 33 fixed on the inner side of the other longitudinal beam 1. An intermediate rod body 32 is installed on one side of the first rod body 31, and a groove cavity is opened inside the second rod body 33 for the intermediate rod body 32 to move.

[0051] During the telescopic adjustment of the cross beam 6, the reinforcement rod 3 can be telescoped at any time, that is, the two longitudinal beams 1 respectively drive the first rod body 31 and the second rod body 33 to move relative to each other. At this time, the first rod body 31 drives the middle rod body 32 to move out of the groove cavity in the second rod body 33, thereby reinforcing the two longitudinal beams 1, thereby ensuring the strength of the lifting device, which is conducive to the stable lifting of the prefabricated wall panels.

[0052] Furthermore, if Figure 7 and Figure 8 As shown, both sides of the inner wall of the groove cavity are fixed with slide rails 34, and both sides of the middle rod body 32 are provided with slide grooves 35 matched with the slide rails 34. Based on this, when the middle rod body 32 moves along the groove cavity, the middle rod body 32 can slide along the slide rails 34 through the slide grooves 35 to limit the middle rod body 32, and can ensure that the first rod body 31 and the second rod body 33 are stable after telescopic adjustment, further realize the reinforcement between the two longitudinal beams 1, ensure the strength of the hoisting device, and facilitate the stable hoisting of the prefabricated wall panel.

[0053] Meanwhile, in this embodiment, if Figure 1-Figure 3 as well as Fig. 9As shown, a locking component 8 for limiting the adjustment structure 7 is also provided on the cross beam 6, and the locking component 8 includes a fixed plate 81 installed on the top of the cross beam plate 61, an adjusting screw 82 is screwed on the fixed plate 81, and one end of the adjusting screw 82 is rotatably connected to a locking plate 83, a locking gear 84 is installed at one end of the rotating rod 72 located outside the cross beam plate 61, and a locking tooth meshing with the locking gear 84 is provided on one side of the locking plate 83; two retractable linkage rods are also connected between the locking plate 83 and the fixed plate 81, and the two linkage rods are symmetrically distributed on both sides of the adjusting screw 82.

[0054] When the cross beam 6 is adjusted, the adjusting screw 82 can be rotated so that the adjusting screw 82 drives the locking plate 83 to move, so that the locking plate 83 is separated from the locking gear 84, and then the rotating rod 72 is rotated by adjusting the hand wheel 71 to realize the telescopic adjustment of the cross beam 6. After the adjustment, the adjusting screw 82 can be rotated in the opposite direction so that the adjusting screw 82 drives the locking plate 83 to move toward the locking gear 84 until the locking teeth on the locking plate 83 engage with the locking gear 84, so as to lock the rotating rod 72 to a limit position, prevent the rotating rod 72 from rotating, and avoid the cross beam 6 from telescopic movement, so that the cross beam 6 remains fixed after adjustment, which is beneficial to the stable use of the lifting device.

[0055] Furthermore, if Figure 2 As shown, first positioning blocks 9 are installed on both sides of the cross beam plate 61 , and first positioning holes 10 corresponding to the first positioning blocks 9 are opened on the opposite sides of the two longitudinal beam members 1 .

[0056] When the lifting device is in the initial state (such as Figure 1 As shown), the first positioning blocks 9 on both sides of the cross beam plate 61 are inserted into the first positioning holes 10, which can ensure the cross beam plate 61 and the two longitudinal beams 1 to be stably connected, thereby ensuring the stability of the lifting device and facilitating the lifting of the prefabricated wall panels.

[0057] Furthermore, if Figure 2 As shown, both sides of the cross beam plate 61 are recessed inward to form slots for the connecting plate 62 to be inserted into, and a second positioning block 11 is installed on the inner wall of the slot, and a second positioning hole 12 corresponding to the second positioning block 11 is opened on one side of the connecting plate 62.

[0058] When the lifting device is in the initial state (such as Figure 1 As shown in the figure, the connecting plate 62 at one end of the movable plate 63 is inserted into the notch, and at the same time the second positioning block 11 is inserted into the second positioning hole 12 to position the connecting plate 62 and the notch, thereby realizing the rapid docking between the two movable plates 63 and the two longitudinal beams 1, which can further ensure the stable connection between the cross beam 6 and the two longitudinal beams 1, which is beneficial to ensure the stability of the lifting device and facilitates the lifting of the prefabricated wall panels.

[0059] Embodiment 2:

[0060] On the basis of implementation one, Figure 1-Figure 6 As shown, the support member 4 is telescopically adjustable, and the support member 4 includes a connecting rod 42 fixed to the bottom of the longitudinal beam member 1, and a support plate 41 connected to the bottom end of the connecting rod 42, an extension rod 44 is installed on the top of the support plate 41, and the extension rod 44 is provided with locking holes 45 distributed at equal intervals along its height direction, the interior of the connecting rod 42 has a telescopic cavity for the extension rod 44 to move, and the bottom of the connecting rod 42 is screwed with a locking bolt 43 that matches the locking hole 45, and a pad 5 is also provided on the top of the support plate 41.

[0061] When the prefabricated wall panels are hoisted, the support member 4 can be telescopically adjusted according to the thickness of the prefabricated wall panels, and the specific adjustment steps are as follows:

[0062] First, unscrew the locking bolt 43 from the locking hole 45, and then pull the support plate 41 downward, so that the support plate 41 drives the extension rod 44 to move along the inside of the connecting rod 42, so as to extend the support plate 41 and the connecting rod 42, thereby increasing the distance between the support plate 41 and the crossbeam plate 61 to meet the thickness of the prefabricated wall panel, and then screw the locking bolt 43 into the corresponding locking hole 45 to screw the extension rod 44 to fix the support plate 41 and the connecting rod 42, thereby realizing the extension and retraction of the support member 4, so that the support member 4 can adapt to prefabricated wall panels of different thicknesses, which is beneficial to the hoisting of prefabricated wall panels of different thicknesses, greatly improving the practicability of the hoisting device.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
