Description

Technical Field

[0001] This utility model belongs to the field of composite beam hoisting technology, and in particular relates to a composite beam hoisting device. Background Technology

[0002] The cross-section of frame beams is generally rectangular or T-shaped. When the floor structure is a precast slab assembly floor, in order to reduce the height occupied by the structure and increase the building clearance, the cross-section of frame beams is often cross-shaped or basket-shaped. In precast monolithic frame structures, precast beams are often made into T-shaped sections. After the precast slabs are installed in place, some concrete is poured again, which forms the so-called composite beam.

[0003] The existing application number 202321253927.7 includes an upper lifting plate and a lower lifting plate detachably connected to the upper lifting plate. The upper lifting plate includes an upper lifting beam and upper lifting parts symmetrically fixed to both sides of the lower end face of the upper lifting beam. The lower end face of the upper lifting beam between the upper lifting parts is also provided with an upper splicing groove. The lower lifting plate includes a lower lifting beam and lower lifting parts symmetrically fixed to both sides of the lower end face of the lower lifting beam. The upper end face of the lower lifting beam between the lower lifting parts is also provided with a lower splicing groove. The upper splicing groove and the lower splicing groove are coaxially threaded through with splicing threaded holes. Both the upper lifting part and the lower lifting part are equally spaced with several steel rope positioning holes. The upper lifting beam on the outside of the upper lifting part and the lower lifting beam on the outside of the lower lifting part are both provided with positioning threaded holes. This solves the problem that traditional lifting tools used for lifting composite beams cannot adapt to the lifting and fixing of composite beams of various shapes.

[0004] Existing hoisting equipment has limitations in the type and size of beams that can be hoisted due to factors such as the length of the traction rope. In addition, because the stress area at the edge is small, excessive stress at the edge during hoisting can easily lead to damage. Utility Model Content

[0010] Preferably, the bottom of the mounting box has equidistant adjustment slots, and the secondary hook forms a partial rotation structure with the mounting box through a steering wheel.

[0011] Preferably, mounting frames are fixedly installed at both ends of the top of the suspension bridge. A traction rod rotates inside the mounting frame. A linkage sprocket is fixed at the outer center of the traction rod at one end. A linkage chain is sleeved on the outside of the linkage sprocket. A rotating sprocket is provided at the end of the linkage chain away from the center of the suspension bridge. A rotating shaft is installed on one side of the rotating sprocket. A rotating motor is installed at one end of the rotating shaft. A traction rope is sleeved on the outside of the traction rod.

[0012] Preferably, the two ends of the traction rope are fixedly connected to the two ends of the moving frame, and the moving frame and the moving plate form a horizontal moving structure through the traction rod and the traction rope.

[0013] Compared with the prior art, the embodiments of this application have the following main advantages:

[0014] 1. This utility model, by setting up a main hook and secondary hooks, increases the number of stress points on the beam during lifting, thus preventing damage to the beam. At the same time, the suspension range of the secondary hook 18 can be adjusted by adjusting the position of the lifting rope 14 according to the size and model of the beam, so as to meet the lifting needs of beams of different sizes and models.

[0015] 2. This utility model, through the setting of a movable plate and a movable frame, allows the movable frame to move during the hoisting process based on the actual position of the beam and the deviation of the center. This movement is achieved through the linkage of the linkage sprocket, linkage chain, and rotating sprocket. The movable frame then moves the positions of the main hook and the secondary hook, thereby enabling adjustment according to the specific position of the beam center and increasing the flexibility of the device.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a composite beam hoisting device, such as Figure 1-4As shown, the system includes a suspension bridge 1, a movable plate 2 fixed at the bottom center of the suspension bridge 1, a movable frame 3 slidably connected to the outside of the movable plate 2, mounting blocks 4 fixed at both ends of the suspension bridge 1, connecting rings 5 ​​installed at both ends of the mounting blocks 4, a connecting chain 6 installed above the connecting rings 5, a connecting beam 7 fixed above the connecting chain 6, and a boom 8 installed at the top center of the connecting beam 7. Movable rollers 9 are fixed at both ends of the movable frame 3 near the center of the suspension bridge 1 at each of the four corners, and a mounting box 10 is fixed at the bottom of the movable frame 3.

[0024] It should be noted that existing hoisting equipment is limited in the type and size of beams that can be hoisted due to limitations such as the length of the traction rope. In addition, because the stress area at the edge is small, excessive stress at the edge during hoisting can easily cause damage. In this solution, the beam is suspended below the suspension bridge 1 and transferred by the boom 8. The position between the moving frame 3 and the moving plate 2 is adjusted according to the specific position of the beam center, and the beam is transferred by the boom 8 after the suspension is completed.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, rotating frames 11 are fixed at each of the four corners of the inner cavity of the mounting box 10. Roller boxes 12 are rotatably connected inside the rotating frames 11, and steering wheels 13 are rotatably connected inside the roller boxes 12. A lifting rope 14 is sleeved on the outside of the steering wheels 13. A lifting plate 15 is fixed to the bottom of the lifting rope 14 on the side closest to the center of the mounting box 10. A connecting block 16 is fixed to the bottom of the lifting rope 14 on the side furthest from the center of the mounting box 10. A main hook 17 is rotatably connected to the bottom center of the lifting plate 15, and a secondary hook 18 is rotatably connected to the bottom center of the connecting block 16. Adjustment grooves are equidistantly spaced inside the bottom of the mounting box 10. The secondary hook 18 forms a partially rotating structure with the mounting box 10 via the steering wheels 13.

[0026] In this embodiment, the position of the lifting rope 14 is adjusted according to the specific size and model of the beam so that the distance between the secondary hooks 18 can meet the dimensions of the four corners of the beam. Since the length of the lifting rope 14 is consistent, the main hook 17 can always be kept balanced after the secondary hooks 18 are adjusted. The beam is suspended from the top center through the main hook 17, and then suspended from the four corners of the beam through the secondary hooks 18. Increasing the number of main hooks 17 increases the number of stress points and avoids beam damage due to concentrated stress points.

[0027] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4As shown, the bottom of the mounting box 10 has equidistant adjustment slots. The secondary hook 18 forms a partial rotation structure with the mounting box 10 via the steering wheel 13. Mounting frames 19 are fixedly installed at both ends of the top of the suspension bridge 1. A traction rod 20 rotates within the mounting frame 19. A linkage sprocket 21 is fixed at the center of the traction rod 20 at one end. A linkage chain 22 is sleeved on the outside of the linkage sprocket 21. A rotating sprocket 23 is located at the end of the linkage chain 22 away from the center of the suspension bridge 1. A rotating shaft is installed on one side of the rotating sprocket 23, and a rotating motor 24 is installed at one end of the rotating shaft. A traction rope 25 is sleeved on the outside of the traction rod 20. The two ends of the traction rope 25 are fixedly connected to the two ends of the moving frame 3. The moving frame 3 and the moving plate 2 form a horizontal movement structure through the traction rod 20 and the traction rope 25.

[0028] In this embodiment, when the position of the movable frame 3 needs to be adjusted, the rotating motor 24 is started, which drives the rotating shaft and rotating sprocket 23 to rotate. The rotating sprocket 23 and the linkage chain 22 drive the linkage sprocket 21 to rotate, and the linkage sprocket 21 drives the traction rod 20 to rotate. Since the traction rope 25 is sleeved on the outside of the traction rod 20, when the traction rod 20 rotates, the position of the movable frame 3 moves along the trajectory of the movable plate 2, thereby enabling the device to adjust according to the position of the beam center and ensuring the stability of the beam when it is lifted.

[0029] In summary, the beam is suspended below the suspension bridge 1 and transferred via the boom 8. The position between the moving frame 3 and the moving plate 2 is adjusted according to the specific location of the beam's center. After the beam is suspended, it is transferred via the boom 8. The position of the lifting ropes 14 is adjusted according to the beam's specific dimensions and model, ensuring the distance between the secondary hooks 18 meets the dimensions of the four corners of the beam. Since the lengths of the lifting ropes 14 are all consistent, the main hook 17 remains balanced after the secondary hooks 18 are adjusted. The beam is suspended from the top center via the main hook 17, and then from the four corners via the secondary hooks 18. Increasing the number of main hooks 17 increases the stress points, preventing beam damage due to concentrated stress. When the position of the movable frame 3 needs to be adjusted, the rotating motor 24 is started. The rotating motor 24 drives the rotating shaft and rotating sprocket 23 to rotate, and the rotating sprocket 23 and the linkage chain 22 drive the linkage sprocket 21 to rotate. The linkage sprocket 21 drives the traction rod 20 to rotate. Since the traction rope 25 is sleeved on the outside of the traction rod 20, when the traction rod 20 rotates, the position of the movable frame 3 moves along the trajectory of the movable plate 2, thereby enabling the device to adjust according to the position of the beam center and ensuring the stability of the beam when it is lifted.
