Description

Technical Field

[0001] This invention relates to the field of prefabricated building installation technology, specifically to an auxiliary device for the installation and positioning of prefabricated building components. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are prefabricated in factories and then transported to the construction site for assembly and installation using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures.

[0003] When installing components on the upper level of prefabricated buildings, the components are relatively heavy and difficult to move and position directly during assembly. Generally, they can only be moved to the assembly position by a traction device. However, most traction devices use traction ropes for hoisting, which are prone to swaying during hoisting. They can only bring the components to a designated range and cannot suspend them to a precise position. Therefore, a prefabricated building component installation and positioning auxiliary device is needed to move the hoisted components on the upper level of the building and flexibly move them to the assembly position to assist in the assembly of the components.

[0017] 2. The installation and positioning auxiliary device for this prefabricated building component, through the setting of the lifting inner frame, guide waist hole, sliding pin and limiting slider, can drive the two anti-slip fixing mechanisms inside to lift synchronously, avoid misalignment between the two anti-slip fixing mechanisms, and form a guide for the lifting of the anti-slip fixing mechanism and a stable connection with the support frame.

By setting the extension platform 1201, the placement slot 1202, and the cleaning slot waist hole 1203, the center of the device can be maintained by counterweighting the surface of the extension platform 1201 when the weight of the accessory is too heavy, thus ensuring the stability of the device.

[0043] The gripping mechanism includes a grip frame 1301, an end shaft 1302, and a second anti-slip sleeve 1303. The grip frame 1301 is disposed on one side of the support frame 1. The end shaft 1302 is fixedly inserted into the inner wall of the grip frame 1301, and the grip frame 1301 is rotatably connected to the support frame 1 through the end shaft 1302. The second anti-slip sleeve 1303 is fixedly sleeved on the outer wall of the grip frame 1301. The grip frame 1301, end shaft 1302, and second anti-slip sleeve 1303 are configured to provide support when the device is pushed forward by the grip frame 1301, and to be positioned at the most suitable height as needed when the device is pulled forward by the grip frame 1301.

[0044] Among them, the two sides of the support frame 1 are integrally provided with reinforcing ribs 14 near the counterweight platform mechanism, and the two sides of the support frame 1 are fixedly connected with reinforcing brackets 15. The reinforcing brackets 15 have a notch on one side to improve the support strength of the support frame 1 to both sides and prevent the support frame 1 from easily deforming.

[0045] Working principle: During use, align the opening of the support frame 1 with the side of the accessory, then push the device to allow the accessory to enter the support frame 1. Simultaneously, pry open the loosening plate 705 to separate the two pressure plates 704. As the device moves forward, the accessory is positioned between the pressure plates 704. Loosen the pressure plates 704, then rotate the rotating handle 902. The screw 901 pushes the threaded cylinder 906 through the thread to lower the inner frame 601. At the same time, the two winding wheels 1003 can achieve transmission through the winding belt 1004, thus ensuring that the two screws 901 rotate synchronously, thereby driving the inner frame 601 to descend synchronously from both sides. After the inner frame 601 descends to a certain height, it pushes the pry plate 807 inward. The pry plate 807 is transmitted through the drive gear 804 and the driven gear 805. The right-angle hook 806 is pressed inward at the bottom of the accessory, causing it to embed into the accessory through the gap. At the same time, the pry plate 807 engages with the locking block 809. Then, the handle 902 is rotated in the opposite direction to raise the inner lifting frame 601. As the inner lifting frame 601 rises, the accessory will also rise. At this time, the downward pressure of the accessory on the right-angle hook 806 will cause the pressure plate 704 to form an inward and downward squeezing trend, and an upward frictional resistance will be formed on the surface of the anti-slip pad 706 to resist the descent of the accessory. This ensures that the accessory can be lifted as the inner lifting frame 601 rises. Then, the device is pushed to the installation position. The screw 901 is rotated again by rotating the handle 902, thereby realizing the height adjustment of the accessory until the accessory is aligned and connected.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
