Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, and in particular relates to a three-dimensional hoisting system for fixed-base curtain wall construction. Background Technology

[0002] In the construction of building curtain walls, the hoisting of exterior facade materials is a critical step. Currently, the industry often uses unauthorized methods such as transporting materials using suspended platforms or hoisting materials using winches. Such operations are prone to safety accidents and have low hoisting efficiency, failing to meet the requirements for hoisting precision and flexibility in curtain wall construction.

[0003] To address the aforementioned issues, this utility model provides a three-dimensional hoisting system for building curtain wall construction. This system enables hoisting operations in three dimensions—front-to-back, left-to-right, and up-down—without moving the hoisting frame. It is also simple to install, highly safe, and highly efficient. Utility Model Content

[0004] The purpose of this invention is to provide a three-dimensional hoisting system for fixed-base curtain wall construction, thereby solving existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a three-dimensional hoisting system for fixed-base curtain wall construction, comprising two hoisting frames, three sets of hoisting pulley assemblies, one steel beam, two steel beam sleeves, bolt assemblies, and one set of prefabricated hanging winches. The front support arm of the hoisting frame serves as a running track for the installation of the hoisting pulley assemblies to achieve the forward and backward movement of the hoisted object. The steel beam is installed between the front support arms of the two hoisting frames via steel beam sleeves and bolt assemblies, and the hoisting pulley assemblies are installed on the steel beam to achieve the left and right movement of the hoisted object. The prefabricated hanging winch is installed on the hoisting pulleys to provide power for hoisting and to achieve the vertical lifting of the hoisted object.

[0006] In one embodiment, the hoisting frame includes a front support, a rear support, a front support arm, a rear support arm, a wire rope, turnbuckles, and a counterweight. The front support includes a lower front support, an upper front support bolted to the lower front support, and a top front support bolted to the upper front support. The rear support includes a lower rear support and an upper rear support bolted to the lower rear support. The front and rear supports are connected by a bolt assembly to secure the rear support arm. The front support is bolted to the front end of the front support at the same horizontal level. Pulleys are provided at the front end of the front support arm, the rear end of the rear support arm, and the top of the top front support. One end of the wire rope is fixed to the front end of the front support arm, and the other end passes through the top pulley of the top front support and the rear pulley of the rear support, and is finally connected to the turnbuckle fixed to the rear support arm. The tension of the wire rope is adjusted and tightened by the turnbuckles.

[0007] In one embodiment, the materials of the front support arm and steel beam of the hoisting frame include steel pipes, I-beams, or H-beams.

[0008] In one embodiment, the hanging pulley assembly includes two pulley seats, a rotating roller, and two sets of bolt assemblies, with each set of bolt assemblies sequentially positioned on one of the two pulley seats. The rotating roller is fitted onto the circumferential side of the bolt between the two upper pulley seats. The steel beam sleeve includes a square steel tube and steel lugs fixed to the side wall of the square steel tube. The steel lugs are fitted onto the circumferential side of the bolt between the two lower pulley seats.

[0009] In one embodiment, the hoisting pulley assembly is secured to the front support arm or steel beam by its own grooved pulley, enabling movement along the front support arm or steel beam; the distance between the two sets of hoisting frames matches the length of the steel beam and can be flexibly adjusted according to the weight of the hoisted object.

[0010] In one embodiment, the steel beam and the steel beam sleeve are fitted together by insertion, and the length and width of the inner cavity of the steel beam sleeve are 2mm to 3mm larger than the length and width of the outer surface of the steel beam.

[0011] The front and rear supports of the hoisting frame are not limited to counterweights. They can be fixed by means of double beam clamps or single beam diagonal steel wire ropes, depending on the structural characteristics of the building. The system can be used in conjunction with a suspended platform or can operate independently.

[0012] This utility model has the following beneficial effects: Achieving three-dimensional hoisting: The front boom moves forward and backward, the steel beam moves left and right, and the winch moves up and down, allowing three-dimensional hoisting operations to be completed without moving the hoisting frame, offering high flexibility.

[0013] High safety: The hoisting frame is fixed in a flexible and stable manner, and the connection of each component is reliable, avoiding safety hazards caused by improper operation.

[0014] Efficiency Improvement: Simple installation and quick commissioning significantly improve the hoisting efficiency of curtain wall construction.

[0015] Wide adaptability: It can be used with suspended platforms or operated independently, and is suitable for curtain wall construction scenarios of different building structures.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
