Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated cantilevered I-beam turnover device. Background Technology

[0002] Cantilevered I-beam turnover equipment is a type of equipment used in prefabricated building construction, specifically designed for the installation, transportation, and turnover of I-beams. Its design goals are typically to improve the construction efficiency of I-beams, reduce labor costs, and ensure the safety and precision of the construction process.

[0003] The existing technology has the following shortcomings: Application number 202221238096.1 proposes a prefabricated I-beam hoisting device for building construction. This device includes cantilevered I-beams, hoisting I-beams, hoisting components, and tensioning components. At least two cantilevered I-beams are arranged side-by-side at intervals and can be detachably assembled and disassembled on the roof of the building. The hoisting I-beams are connected to the cantilever ends of each cantilevered I-beam. The hoisting components include components installed on... The invention comprises a hoisting mechanism for I-beams, including fixed blocks and a hoisting winch installed at the bottom of the fixed blocks. Two fixed blocks are spaced apart along the length of the I-beam. A hoisting wire rope is wound around the hoisting winch, with a lifting ring connected to one end. A hook, U-shaped in shape, with a U-shaped limiting groove adapted to the cross-section of the I-beam, is attached to the lifting ring. The traction assembly includes a traction winch with a traction wire rope wound around it, one end of which is connected to the lifting ring. This invention ensures the safety of the I-beam and construction personnel.

[0004] The aforementioned device assembles the cantilevered I-beams using pre-embedded holes, threaded sleeves, and fastening bolts. After assembly, the cantilevered I-beams cannot be easily disassembled. To ensure construction safety, maintenance of unstable cantilevered I-beams is inconvenient. The flexibility of the assembly structure could be further improved. In addition, the installation of the pulling winch requires installation on the corresponding floor, and its use is limited to the current floor. Several guide pulleys are also required to prevent excessive wear on the wire rope of the pulling winch. The installation process is cumbersome and not suitable for use on multiple floors.

[0014] Compared with the prior art, this utility model provides a prefabricated cantilevered I-beam turnover device, which has the following beneficial effects:

[0015] 1. This prefabricated cantilevered I-beam turnover equipment includes an assembly base, a cantilevered I-beam, a limiting plate, a crossbeam, an extended I-beam, and a base. The cantilevered I-beam can be directly inserted into the assembly base, and the limiting plate can restrict the position of the cantilevered I-beam within the assembly base to prevent it from falling out. The installation of the cantilevered I-beam is relatively flexible. When it is necessary to perform stability testing and maintenance on the cantilevered I-beam, the cantilevered I-beam can be pulled outward directly after the crossbeam is disassembled, thus improving the flexibility of the cantilevered I-beam assembly.

[0016] 2. This prefabricated cantilevered I-beam turnover equipment consists of a pull-back assembly, an extended I-beam, a base, a small motor, a hook assembly, a hook groove, and a hydraulic rod. When the hoisted beam reaches the corresponding floor, the hydraulic rod pushes the outer end of the extended I-beam close to the wire rope. The small motor rotates, causing the hook assembly to extend. The hook groove aligns with the wire rope. Controlling the hydraulic rod to retract allows the extended I-beam, along with the hook assembly and wire rope, to be brought back to the corresponding floor, facilitating unloading. Depending on the floor height, different pull-back assemblies can be used. This ensures the safety of construction personnel, features a simple installation structure, is easy to disassemble, and allows for convenient recycling later. It is suitable for multi-floor use.

[0026] The hook groove 905 facilitates the hooking of the wire rope 6, and the hook assembly 904 can be extended by the small motor 903.

[0027] In this embodiment, there are several sets of mounting bases 1. The mounting base 1 is provided with a groove that is compatible with the cantilevered I-beam 2. The mounting base 1 is fixedly installed on the top of the building 7 by bolts.

[0028] Specifically, the mounting base 1 facilitates the installation of the cantilevered I-beam 2.

[0029] In this embodiment, the limiting plate 3 is integrally formed with the cantilevered I-beam 2, and the crossbeam 4 is installed at the outer end of the cantilevered I-beam 2 through the mounting groove 11 and fixed by bolts;

[0030] Specifically, the position of the cantilevered I-beam 2 on the mounting base 1 can be restricted by the limiting plate 3.

[0031] In this embodiment, the hoisting winch 5 is fixedly installed at the bottom of the crossbeam 4. There are two sets of hoisting winches 5 at the bottom of each set of crossbeams 4, and they are arranged symmetrically. The wire rope 6 is wound around the output end of the hoisting winch 5, and the end of the wire rope 6 is provided with a hook.

[0032] Specifically, the hoisting winch 5 and wire rope 6 can be used to easily hoist the required I-beams.

[0033] In this embodiment, the base 902 is provided with a groove for the extension I-beam 901 to fit. The extension I-beam 901 is inserted into the base 902. The bottom of the hydraulic rod 10 is fixedly installed in the building 7 of the corresponding floor. The output end of the hydraulic rod 10 is fixedly installed at the tail end of the extension I-beam 901.

[0034] Specifically, the extension and retraction of the I-beam 901 can be controlled by the hydraulic rod 10.

[0035] In this embodiment, a small motor 903 is fixedly installed on one side of the outer end of the extended I-beam 901. The output end of the small motor 903 is threaded. The output end of the small motor 903 passes through the extended I-beam 901 and is inserted into the hook assembly 904. There is a threaded connection between the hook assembly 904 and the small motor 903. The position of the pull-back assembly 9 corresponds to the steel wire rope 6.

The crossbeam 4 is fixed to the extended outer end of the cantilevered I-beam 2 through the mounting groove 11 and bolts, and provides installation space for the hoisting winch 5. The installation of the cantilevered I-beam 2 is relatively flexible. When it is necessary to perform stability testing and maintenance on the cantilevered I-beam 2, the cantilevered I-beam 2 can be pulled outward directly after the crossbeam 4 is disassembled, improving the flexibility of the assembly of the cantilevered I-beam 2. When hoisting the I-beam, the wire rope 6 is released by the hoisting winch 5, and the hoisting mechanism at the end of the wire rope 6 is used to fix the I-beam to be installed. The I-beam is equipped with a hoisting winch 5 that winds up the wire rope 6 to lift the corresponding I-beam. When it reaches the corresponding floor, the hydraulic rod 10 can be driven to push the outer end of the extended I-beam 901 close to the wire rope 6, controlling the small motor 903 to rotate. Under the action of the threaded structure, the hook assembly 904 is extended, and the hook groove 905 corresponds to the wire rope 6. Controlling the hydraulic rod 10 to retract allows the extended I-beam 901 to be pulled back to the corresponding floor along with the hook assembly 904. During the process, the wire rope 6 is also pulled back, allowing the hoisted I-beam to smoothly enter the floor for easy unloading. Depending on the height of the hoisted floor, different floor pull-back assemblies 9 can be used. This ensures the safety of construction personnel, has a simple installation structure, is easy to disassemble, and can be easily recycled later, making it suitable for multi-floor use.
