Description

Technical Field

[0001] The utility model relates to the technical field of purlin hoisting construction, in particular to a super-long light steel structure purlin hoisting device. Background Art

[0002] Currently, purlin installation is typically performed on buildings, where the purlins are hoisted integrally with the roof structure or other supporting structures. This integral installation prevents deformation and damage. However, in offshore photovoltaic projects, where the photovoltaic panels support a large and extensive structure, purlins, as an integral part of the supporting steel structure, are particularly important. Purlins must also be exceptionally long and lightweight.

[0003] Traditional purlin hoisting generally uses two or more slings and U-shaped clips for hoisting. During the hoisting process, if the purlin is too long, a slight deviation in the hoisting position will cause imbalance and easily cause the purlin to deform and bend, causing inconvenience to subsequent construction.

[0004] In view of the above problems, a super-long light steel structure purlin lifting device is now provided. Utility Model Content

[0005] In order to achieve the above-mentioned purpose of the utility model and address the above-mentioned technical problems, the utility model provides an extra-long light steel structure purlin lifting device to solve the problem that extra-long light steel structure purlins are easily damaged and deformed during the lifting process.

[0006] The technical solution includes a truck crane, a sling, a truss structure, a number of hinges and a latch fixing structure;

[0007] The sling is connected to the hook of the truck crane, and the truss structure is connected to the sling. The truss structure is used to load the steel purlins. The hinge is fixed to the side of the truss, and the latch fixing structure is installed at the top of the truss structure. The hinge and latch fixing structure form a side door on one side of the truss structure. This provides a new lifting device that avoids the damage to the purlins caused by traditional lifting fixtures, ensures the qualified rate of the structure, and solves the problem of deformation of ultra-long lightweight steel purlins during lifting.

[0008] The truck crane is a lightweight mobile device that can be quickly moved and deployed in different locations. The beneficial effect is that it improves the flexibility and adaptability of the lifting device, making it easier to use in different environments.

[0009] The lifting belt is a connecting belt for mechanical lifting and hoisting, ensuring stability and safety during the lifting process.

[0010] The truss structure is connected to the aluminum alloy frame through U-shaped buckles and a scissor brace is set in the middle to form a stable structure;

[0011] The space for loading steel structure purlins is formed inside the truss structure, providing a stable lifting platform to protect the purlins from damage.

[0012] A bottom frame is fixedly mounted at the bottom of one side of the truss structure, and a plurality of hinges are evenly distributed. The bottom of the hinge is hinged to the top of the bottom frame, and the top of the hinge is connected to the top of the truss via the latch fixing structure to form the side door. When the side door is closed, it is secured using the latch fixing structure. The side door design facilitates the rapid loading and unloading of purlins, thereby improving work efficiency.

[0013] The height of the bottom frame is half of the height of the entire truss structure, providing suitable support and stability. The design of the truss structure is optimized to ensure stability during the lifting process.

[0014] The latch fixing structure is fixed to the top of the truss by welding, providing a strong connection, enhancing the stability and safety of the side door and ensuring the safety of the purlin during the lifting process.

[0015] The technical solution provided by the embodiment of the utility model has the following beneficial effects: the solution provides a lifting device for ultra-long light steel structure purlins. Unlike traditional lifting fixtures, the device utilizes the load-bearing characteristics of the aluminum alloy truss structure to lift the purlins, without any damage to the ultra-long light structure purlins, ensuring the qualified rate of the structure, and solving the problem of stress deformation during the lifting process of ultra-long light steel structure purlins in the prior art;

[0016] At the same time, it can realize the fast and effective lifting of multiple ultra-long light-weight structural purlins at one time, greatly reducing working time and improving work efficiency. The truck crane can realize full-scale rotation and movement to adapt to various working environments, fundamentally optimizing the purlin lifting process and reducing the workload of workers.

[0017] In addition, the device has a simple structure, is easy to manufacture, has low cost, and its components can be recycled multiple times to effectively improve economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The sling 2 is connected to the hook of the truck crane 1, and the truss structure 3 is connected to the sling 2. The truss structure 3 is used to load the steel structure purlins. The hinge 4 is fixed to the side of the truss, and the pin fixing structure is set on the top of the truss structure 3. The hinge 4 and the pin fixing structure form a side door on one side of the truss structure 3.

[0033] The truck crane 1 is a light mobile equipment.

[0034] The lifting belt 2 is a connecting belt for mechanical lifting and hoisting.

[0035] The truss structure 3 is connected to the aluminum alloy frame through U-shaped buckles and a scissor brace is set in the middle;

[0036] A space for loading steel structure purlins is formed inside the truss structure 3 .

[0037] A bottom frame 7 is fixed at the bottom of one side of the truss structure 3, and several hinges 4 are evenly distributed. The bottom of the hinge 4 is hinged to the top of the bottom frame 7, and the top of the hinge 4 is connected to the top of the truss through a latch fixing structure to form a side door. After the side door is closed, it is fixed using the latch fixing structure.

[0038] The height of the bottom frame 7 is half the height of the entire truss structure 3 .

[0039] The bolt fixing structure is fixed to the top of the truss by welding.

[0040] When using the present invention, it is first necessary to check whether the various functions of the truck crane 1 are operating normally, whether the sling 2 is damaged, and whether the truss structure 3 meets the purlin length and can fix the purlin position. If everything is normal, it can be used.

[0041] When in use, after the truck crane 1 is driven to the designated position, the legs are extended, and then the truck crane 1 and the truss structure 3 are respectively connected with the slings 2.
