Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a prefabricated component on-site hoisting device. Background Technology

[0002] Precast components refer to building components that are prefabricated in a factory or on-site according to design specifications. They are mainly made of materials such as steel, wood, or concrete. These components achieve millimeter-level precision control through standardized production processes, which can significantly shorten the construction period and reduce construction waste, in line with the development trend of modern prefabricated buildings. Precast concrete components are required in housing projects. Among the precast concrete components in housing projects, precast beams are needed to support the building's load. When installing precast beams, hoisting equipment is required to assist in their installation.

[0003] Currently, the common method for hoisting precast beams is to tie steel wire ropes to the exposed reinforcing bars on the beam and then use a fixed tower crane. However, the steel wire ropes exert tension on the reinforcing bars during hoisting, which can easily cause deformation. This necessitates restoring the deformed reinforcing bars after installation, increasing the installation steps and potentially affecting the load-bearing capacity of the precast beam. Therefore, improvements are needed. Utility Model Content

[0064] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a prefabricated component on-site hoisting device.

[0065] A precast component hoisting device includes a support frame 1 and a drive frame 2, with the drive frame 2 fixedly connected to the support frame 1. It also includes: a lifting ring 3, mounted on and fixedly connected to the support frame 1; a drive groove 4, formed within the drive frame 2; two drive blocks 5, symmetrically arranged within the drive groove 4 and slidably connected to it; a drive component, mounted on the drive frame 2, for adjusting the spacing between the drive blocks 5 to facilitate hoisting precast beams of different lengths; a fixing mechanism, mounted on the drive blocks 5, for clamping and fixing the reinforcing bars on the precast beams; a fixing frame 6, mounted on and fixedly connected to the drive blocks 5; a fixing groove 7, formed on the fixing frame 6; two fixing blocks 8, symmetrically arranged within the fixing groove 7 and slidably connected to it; and a pressing mechanism, mounted within the support frame 1, for pressing and fixing the precast beams to prevent swaying during hoisting.

[0066] Reference Figure 3 In a preferred embodiment, the driving component includes: a first driving shaft 9, which is disposed on the driving frame 2 and rotatably connected to the driving frame 2, and the driving block 5 is threadedly connected to the first driving shaft 9; a driving plate 10, which is fixedly connected to the first driving shaft 9; a second driving shaft 11, which is fixedly connected to the driving plate 10; and a driving sleeve 12, which is rotatably connected to the second driving shaft 11.

[0067] During operation, rotating the drive sleeve 12 causes the drive plate 10, which is fixedly connected to the second drive shaft 11, to rotate. This causes the first drive shaft 9, which is fixedly connected to the drive plate 10, to rotate on the drive frame 2, thereby causing the drive block 5, which is threadedly connected to the first drive shaft 9, to rotate. This causes the drive block 5 to slide relative to the drive groove 4, thereby moving the fixed frame 6.

[0068] Reference Figure 5 In a preferred embodiment, the fixing mechanism includes: a fixing rod 13, which is disposed within the fixing frame 6 and fixedly connected to the fixing frame 6; a fixing sleeve 14, which is slidably connected to the fixing rod 13 and to the fixing frame 6; a fixing plate 15, which is fixedly connected to the fixing sleeve 14; and an elastic component disposed on the fixing sleeve 14.

[0069] During operation, pressing the fixed plate 15 moves the fixed plate 15 closer to the fixed frame 6, causing the fixed sleeve 14, which is fixedly connected to the fixed plate 15, to slide on the fixed rod 13.

[0070] Reference Figure 5 In a preferred embodiment, the elastic component includes: an elastic block 16, which is disposed on the fixed sleeve 14 and fixedly connected to the fixed sleeve 14; an elastic spring 17, one end of which is fixedly connected to the elastic block 16 and the other end of which is fixedly connected to the fixed frame 6; and a rotating component disposed on the elastic block 16.

[0071] When in operation, it moves the elastic block 16, which compresses the elastic spring 17 that is fixedly connected to the elastic block 16, generating elastic potential energy.

[0072] Reference Figure 5 In a preferred embodiment, the rotating component includes: two first rotating shafts 18, which are symmetrically arranged on the elastic block 16 and fixedly connected to the elastic block 16; a rotating plate 19, which is rotatably connected to the first rotating shafts 18; a second rotating shaft 20, which is rotatably connected to the rotating plate 19 and fixedly connected to the fixed block 8; and a sliding component, which is disposed on the fixed block 8.

[0073] During operation, the rotating plate 19, which is rotatably connected to the first rotating shaft 18, rotates, causing the fixed block 8, which is fixedly connected to the second rotating shaft 20, to slide in the fixed groove 7, thus moving the fixed blocks 8 away from each other.

[0074] Reference Figure 5 In a preferred embodiment, the sliding component includes: a sliding frame 21, which is disposed on the fixed block 8 and fixedly connected to one of the fixed blocks 8; and a sliding block 22, which is disposed on the fixed block 8, fixedly connected to the other fixed block 8, and slidably connected to the sliding frame 21.

[0075] During operation, the sliding block 22 moves outward toward the sliding frame 21 until the sliding door quickly and completely detaches from the sliding frame 21. Then, the steel bars on the precast beam are placed onto the sliding frame 21, and the fixing plate 15 is released, causing the elastic spring 17 to release its elastic potential energy, which drives the sliding block 22 to slide inward toward the sliding frame 21 until the sliding block 22 and the sliding frame 21 completely overlap.

[0076] Reference Figure 4 In a preferred embodiment, the extrusion mechanism includes: an extrusion shaft 23, which is disposed on the support frame 1 and fixedly connected to the support frame 1; an extrusion disc 24, which is disposed on the extrusion shaft 23 and fixedly connected to the extrusion shaft 23; two extrusion blocks 25, which are symmetrically disposed on the extrusion shaft 23, threadedly connected to the extrusion shaft 23, and slidably connected to the support frame 1; and a transmission component, which is disposed on the extrusion blocks 25.

[0077] During operation, rotating the extrusion disc 24 causes the extrusion shaft 23, which is fixedly connected to the extrusion disc 24, to rotate on the support frame 1, causing the extrusion block 25, which is threadedly connected to the extrusion shaft 23, to rotate and slide within the support frame 1, so that the extrusion blocks 25 move away from each other.

[0078] Reference Figure 4In a preferred embodiment, the transmission components include: two first transmission shafts 26 symmetrically arranged on the extrusion block 25 and fixedly connected to the extrusion block 25; a transmission plate 27 rotatably connected to the first transmission shafts 26; a second transmission shaft 28 rotatably connected to the transmission plate 27; a transmission block 29 disposed on the second transmission shaft 28, fixedly connected to the second transmission shaft 28, and slidably connected to the support frame 1, wherein the size of the transmission block 29 is larger than the size of the hole on the support frame 1; a transmission rod 30 disposed on the transmission block 29, fixedly connected to the transmission block 29, and slidably connected to the support frame 1; and a connecting plate 31 disposed on the transmission rod 30 and fixedly connected to the transmission rod 30.

[0079] During operation, the transmission plate 27, which is rotatably connected to the first transmission shaft 26, rotates, causing the transmission block 29, which is fixedly connected to the second transmission shaft 28, to slide within the support frame 1. This causes the transmission rod 30, which is fixedly connected to the transmission block 29, to slide into the support frame 1, causing the connecting plate 31, which is fixedly connected to the transmission rod 30, to move closer to the surface of the precast beam until the connecting plate 31 contacts the surface of the precast beam.

[0080] Working principle: In use, first connect the lifting ring 3 to the hook of the tower crane, then rotate the drive sleeve 12, which drives the drive plate 10 fixedly connected to the second drive shaft 11 to rotate, causing the first drive shaft 9 fixedly connected to the drive plate 10 to rotate on the drive frame 2, which drives the drive block 5 threadedly connected to the first drive shaft 9 to rotate, causing the drive block 5 to slide relative to each other in the drive groove 4, thus moving the fixed frame 6 to achieve adjustment according to the precast beams of different lengths; then press the fixed plate 15, which moves the fixed plate 15 closer to the fixed frame 6, causing the fixed sleeve 14 fixedly connected to the fixed plate 15 to slide on the fixed rod 13, thereby driving the elastic block 16 to move, so that it moves relative to the fixed frame 6. The elastic spring 17, which is fixedly connected to the elastic block 16, is compressed, generating elastic potential energy. This causes the rotating plate 19, which is rotatably connected to the first rotating shaft 18, to rotate. This causes the fixed block 8, which is fixedly connected to the second rotating shaft 20, to slide in the fixed groove 7. This causes the fixed blocks 8 to move away from each other, causing the sliding block 22 to move outward from the sliding frame 21 until the sliding door is completely separated from the sliding frame 21. Then, the steel bars on the precast beam are placed on the sliding frame 21. The fixed plate 15 is then released, causing the elastic spring 17 to release its elastic potential energy. This causes the sliding block 22 to slide inward from the sliding frame 21 until the sliding block 22 and the sliding frame 21 are completely overlapped, thereby fixing the steel bars on the precast beam.

[0081] Next, the extrusion disc 24 is rotated, causing the extrusion shaft 23, which is fixedly connected to the extrusion disc 24, to rotate on the support frame 1. This causes the extrusion block 25, which is threadedly connected to the extrusion shaft 23, to rotate and slide within the support frame 1. This causes the extrusion blocks 25 to move away from each other, thereby causing the transmission plate 27, which is rotatably connected to the first transmission shaft 26, to rotate. This causes the transmission block 29, which is fixedly connected to the second transmission shaft 28, to slide within the support frame 1. This causes the transmission rod 30, which is fixedly connected to the transmission block 29, to slide into the support frame 1. This causes the connecting plate 31, which is fixedly connected to the transmission rod 30, to move closer to the surface of the precast beam until the connecting plate 31 contacts the surface of the precast beam. This fixes the precast beam and prevents it from shaking during hoisting.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
