It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] like Figures 1 to 5 FIG. 1 is a structural diagram of an assembled building hoisting frame provided by an embodiment of the present invention, comprising a fixed ring 1, a movable ring 3, a synchronous drive mechanism 100, an anti-deflection mechanism 200, an elastic pulling mechanism 300 and a multi-directional clamping mechanism 400. The movable ring 3 is rotatably installed in the fixed ring 1, and a cross 2 is fixedly installed on the inner side of the movable ring 3. The cross 2 moves synchronously with the movable ring 3. The synchronous drive mechanism 100 is installed on the fixed ring 1 and the movable ring 3, and drives the movable ring 3 to move synchronously when the synchronous drive mechanism 100 is working. 3 and the cross 2 rotate along the inside of the fixing ring 1; the anti-deflection mechanism 200 is provided with a plurality of them, and is arranged at equal angles on the outside of the fixing ring 1 to avoid shaking during hoisting; the elastic pulling mechanism 300 is symmetrically installed on the upper surface of the cross 2, and the top of the elastic pulling mechanism 300 is connected to the external crane; the multi-directional clamping mechanism 400 is installed at the movable end of the elastic pulling mechanism 300, and the multi-directional clamping mechanism 400 moves synchronously with the elastic pulling mechanism 300, and clamps the building components during the movement.

[0041] The present application provides an assembled building hoisting frame, which can position and clamp building components from multiple directions and has high structural stability. After the building components are fixed, they are not prone to shaking during the hoisting process, and the hoisting safety is high. The position of the building components can be adjusted according to the needs of the hoisting to ensure that the building components are quickly and accurately delivered to the assembly station.

[0042] In one example of the present invention, the number of the anti-deflection mechanism 200, the elastic pulling mechanism 300 and the multi-directional clamping mechanism 400 can be adjusted as needed, such as 2 groups, 3 groups, 4 groups, etc. The anti-deflection mechanism 200, the elastic pulling mechanism 300 and the multi-directional clamping mechanism 400 are evenly distributed on the fixing ring 1 at different angles, and are used to position and clamp the building components from multiple directions and perform subsequent lifting work, thereby improving the stability of the building components during lifting.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment of the present invention, the synchronous drive mechanism 100 includes a driving gear shaft 4, an external tooth portion 5 and a receiving cavity 6;

[0044] The driving gear shaft 4 is rotatably mounted inside the fixed ring 1, and the outer tooth portion 5 is mounted on the outer side of the movable ring 3, and the driving gear shaft 4 is meshed with the outer tooth portion 5;

[0045] The fixing ring 1 is provided with a receiving cavity 6 for the driving gear shaft 4 to rotate.

[0046] In one embodiment of the present invention, the top end of the driving gear shaft 4 is connected to the external driving motor 7 on the fixing ring 1 through a coupling; the driving motor 7 is a forward and reverse motor, and the driving motor 7 is electrically connected to an independently arranged controller;

[0047] In actual use, the drive motor 7 is operated through the arranged controller, and the drive motor 7 drives the drive gear shaft 4 to rotate along the fixed ring 1 through the coupling. Since the drive gear shaft 4 is meshed with the outer tooth portion 5, the outer tooth portion 5, the movable ring 3 and the cross 2 can be driven in turn to rotate synchronously along the fixed ring 1 when the drive gear shaft 4 rotates, and the fixed vertical rod 17 installed on the cross 2 rotates synchronously therewith to adjust the lifting angle.

[0048] like Figure 1 As shown, as another preferred embodiment of the present invention, the anti-deflection mechanism 200 includes a lock buckle 8, a limiting rope 9, a fixing bracket 10 and a winch 11;

[0049] The lock buckles 8 are fixedly mounted on the outside of the fixing ring 1, and each lock buckle 8 is installed with a limit rope 9;

[0050] A fixing bracket 10 is arranged at the bottom end of the fixing ring 1 , a winch 11 is installed on the fixing bracket 10 , and the bottom end of the limiting rope 9 extends into the inside of the winch 11 .

[0051] In one example of the present invention, when the fixing ring 1 is being lifted or lowered, winches 11 at multiple positions work synchronously to ensure that when the fixing ring 1 moves, multiple limiting ropes 9 move along the winches 11, which can effectively prevent the fixing ring 1 from deflecting during the lifting process.

[0052] like Figure 1 , Figure 2 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic pulling mechanism 300 includes a support 12, a roller 1 13, a roller 1 13, a steel wire rope 14, a roller 2 15, a movable block 16 and an elastic support member 20;

[0053] The support 12 is fixedly mounted on the cross 2, a roller 13 is rotatably arranged at the top of the support 12, a roller 2 15 is rotatably arranged inside the cross 2, and the roller 13 and the roller 2 15 are connected by a steel wire rope 14;

[0054] A movable block 16 is slidably installed inside the cross 2 , one side of the movable block 16 is connected to the end of the steel wire rope 14 , and an elastic support member 20 is installed on the other side of the movable block 16 .

[0055] In one embodiment of the present invention, the fixing ring 1 and the cross 2 are placed in advance on the top of the building component to be hoisted, and the wire rope 14 moves along the roller 13 and the roller 2 15 under the action of the crane, wherein the roller 13 rotates along the support 12, and the roller 2 15 rotates along the cross 2. At the same time, the wire rope 14 also pulls the movable block 16 to slide along the cross 2. During this process, the elastic support member 20 is subjected to force and elastically deforms.

[0056] like Figure 2 and Figure 5 As shown, as another preferred embodiment of the present invention, the multi-directional clamping mechanism 400 includes a fixed vertical rod 17, a limiting groove 18, a limiting groove 2 19 and a fixed horizontal rod 21;

[0057] The fixed vertical rod 17 is fixedly installed at the bottom end of the movable block 16, and the fixed vertical rod 17 is arranged in the same number as the movable block 16;

[0058] The cross 2 is provided with a first limiting groove 18 for the movable block 16 to slide, and the cross 2 is also provided with a second limiting groove 19 for the fixed vertical rod 17 to slide, and the first limiting groove 18 and the second limiting groove 19 are connected;

[0059] The bottom ends of the plurality of fixed vertical rods 17 are all provided with fixed horizontal rods 21 for hoisting the building components.

[0060] In one example of the present invention, when the steel wire rope 14 is forced to pull the movable block 16 to slide along the limiting groove 18, the elastic support member 20 in the limiting groove 18 is elastically deformed under the force, and the fixed vertical rod 17 moves synchronously with the movable block 16. At the same time, the fixed vertical rod 17 slides along the limiting groove 2 19, so that when the building components are hoisted, the fixed cross bar 21 is used to clamp the building components from multiple directions, thereby completing the fixation of the building components.

[0061] like Figure 2 As shown, as another preferred embodiment of the present invention, a protective pad 22 is arranged on one side opposite to the plurality of fixed vertical rods 17 and the fixed horizontal rod 21 .

[0062] In one example of the present invention, the protective pad 22 is made of rubber material to prevent the surface of the building component from being damaged during the hoisting process.

[0063] To sum up, in actual use, the cross 2 and the movable ring 3 are installed in the fixed ring 1, and the fixed ring 1 and the cross 2 are placed on the top of the building component, so that the fixed cross bar 21 contacts the building component, and the wire rope 14 moves along the roller 13 and the roller 2 15 under the action of the crane, wherein the roller 13 rotates along the support 12, and the roller 2 15 rotates along the cross 2. At the same time, the wire rope 14 also pulls the movable block 16 to slide along the cross 2, and the elastic support member 20 is elastically deformed under force, and the fixed vertical rod 17 moves synchronously with the movable block 16. At the same time, the fixed vertical rod 17 slides along the limiting groove 2 19, so that when the building component is hoisted, the fixed cross bar 21 is used to clamp the building component from multiple directions, thereby completing the fixing of the building component. After the building component is lifted off the ground, the winches 11 at multiple positions work synchronously to ensure the fixed ring When the building component 1 moves, the plurality of limit ropes 9 move along the winch 11, which can effectively prevent the fixing ring 1 from deflecting during the hoisting process. When the angle of the building component needs to be adjusted, the driving motor 7 is operated through the arranged controller, and the driving motor 7 drives the driving gear shaft 4 to rotate along the fixing ring 1 through the coupling. Since the driving gear shaft 4 is meshed with the outer tooth portion 5, the outer tooth portion 5, the movable ring 3 and the cross 2 can be driven in sequence to rotate synchronously along the fixing ring 1 when the driving gear shaft 4 rotates, and the fixed vertical rod 17 installed on the cross 2 rotates synchronously therewith. The hoisting frame can position and clamp the building component from multiple directions, and has high structural stability. After the building component is fixed, it is not easy to shake during the hoisting process, and the hoisting safety is high. The position of the building component can be adjusted according to the needs of hoisting to ensure that the building component is quickly and accurately delivered to the assembly station.

Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
