Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated beam hoisting mechanisms, in particular to a prefabricated beam hoisting mechanism for assembled buildings. Background Art

[0002] Precast beams are concrete building components manufactured in factories and transported to construction sites for installation. Large concrete mixer trucks pour concrete into molds, and before the concrete solidifies, rebar and other additives are pre-placed in the molds. Precast beams are widely used in modern industrial, transportation, and civil construction, including bridges, tunnels, parking lots, large commercial centers, and stadiums. Precast beams are widely used in the construction industry due to their high production efficiency, consistent quality, and strong structural compressive strength. They can also be designed and produced to meet specific requirements in various shapes, sizes, and load-bearing capacities. However, existing precast beams for prefabricated buildings require the use of a hoisting mechanism for installation.

[0003] Existing prefabricated building beam lifting mechanisms generally only use lifting ropes and hooks to lift prefabricated building beams. However, when using a single lifting rope and hook, the prefabricated building beams are heavy and large in size, so they are prone to shaking during the lifting process, which will make the lifting stability of the prefabricated building beams poor, and further cause the prefabricated building beams to accidentally fall from a height, which will be dangerous and make the lifting mechanism less safe when used.

[0004] Therefore, it is necessary to provide a prefabricated building beam lifting mechanism to solve the above technical problems. Utility Model Content

[0020] 1. Compared with the existing technology, the prefabricated building beam lifting mechanism, through the coordinated use of structures such as mounting strips, card slots, fixing components, slide slots, baffles, fixing slots, push strips and clamping components, can not only clamp one side and the bottom of the prefabricated building beam, but also allow the hook to form a closed loop, solving the problem of poor stability of the prefabricated building beam lifting when a single lifting rope and hook are used, avoiding the accidental fall of the prefabricated building beam from a height during the lifting process, preventing danger, and improving the safety of the lifting mechanism when in use.

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-5 When the lifting rod 1 is lifted up, the lifting column 1 is tightened, and the lifting column 1 is tightened.

[0031] The moving assembly includes a motor 11 installed on one side of the mounting frame 1. The output end of the motor 11 passes through the interior of the mounting frame 1 and is fixedly connected to a bidirectional screw rod 12. The outer surface of the bidirectional screw rod 12 is threadedly connected to two moving blocks 13. The moving block 13 is T-shaped and the lifting rope 3 is fixedly connected to the bottom of the moving block 13. The two moving blocks 13 are respectively threaded on two different threads on the outer surface of the bidirectional screw rod 12 and the two sides are slidingly connected to the two sides of the inner wall of the mounting frame 1. The tops of the two moving blocks 13 are fixedly connected to hinge blocks 14. The interior of the hinge block 14 is hinged with a connecting bar 15. One side of the connecting bar 15 is hinged with a connecting block 25. The top of the connecting block 25 is fixedly connected to a connecting plate 16. The top of the connecting plate 16 is fixedly connected to a connecting ring 17. The connecting ring 17 is used to be fixed to a hook on a crane. The bottom of the connecting plate 16 is fixedly connected to the top of another connecting bar 15.

[0032] The fixing component includes a mounting groove 18 opened on one side of the inner wall of the card slot 5, and a threaded rod 19 is rotatably penetrated on one side of the inner wall of the mounting groove 18. One end of the threaded rod 19 is fixedly connected to a fixing column 20, and the other end of the threaded rod 19 is fixedly connected to a rotating block 21. The diameter of the sliding column is consistent with the inner wall of the fixing groove 9. One end of the threaded rod 19 is threadedly penetrated to one side of the mounting bar 4 and the rotating block 21 is located outside the mounting bar 4.

[0033] The clamping assembly includes a threaded rod 22 that is threaded through the top of the mounting bar 4. The top of the threaded rod 22 is connected to a driving block 23. The bottom end of the threaded rod 22 passes through the mounting bar 4 and is fixedly connected to the limiting plate 2. The top of the limiting plate 2 is fixedly connected to the limiting bar 24. The top of the limiting bar 24 slides through the top of the mounting bar 4.

[0034] Working principle: When in use, first put the connecting ring 17 on the hook of the crane, then adjust the distance between the two hooks 6 according to the size of the prefabricated beam of the assembled building, and start the motor 11 so that the output end of the motor 11 drives the bidirectional screw rod 12 to rotate. At this time, the two moving blocks 13 will approach each other as the bidirectional screw rod 12 rotates, and then the two lifting ropes 3 respectively drive the two mounting bars 4 to approach each other until the distance between the two hooks 6 is consistent with the size of the prefabricated beam of the assembled building. At this time, the motor 11 is turned off, so that the distance between the two hooks 6 can be adjusted according to the size of the prefabricated beam of the assembled building;

[0035] Then, hang the two hooks 6 on the prefabricated beam of the assembled building that needs to be hoisted. At this time, the top of the limit plate 2 and the bottom of the installation strip 4 are in a fit state. After hanging them together, let the crane lift the prefabricated beam of the assembled building slightly upward, and then rotate the driving block 23. At this time, the driving block 23 drives the threaded rod 22 to rotate, and then the limit plate 2 drives the threaded rod 22 to rotate upward until the bottom of the limit plate 2 and the bottom of the prefabricated beam of the assembled building are in contact with each other. At this time, the limit strip 24 can be used to lift the prefabricated beam of the assembled building. The bottom and one side of the beam are limited, and then the push bar 10 is moved upward, so that the push bar 10 drives the baffle 8 to move upward until the top of the baffle 8 is engaged in the inside of the slot 5. At this time, the rotating block 21 is rotated again to make the rotating block 21 drive the threaded rod 19 to rotate. At this time, the threaded rod 19 will drive the fixed column 20 to move toward the baffle 8 until the rotating block 21 cannot rotate. At this time, the rotating block 21 is engaged in the inside of the fixed slot 9, thereby forming a closed loop between the baffle 8 and the hook 6, and then it is lifted by a crane.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
