Description

Technical Field

[0001] The invention relates to the technical field of steel structure building construction devices, and in particular to a large-scale steel structure building construction device based on BIM technology. Background Art

[0002] BIM stands for Building Information Model, which is a relatively mature technology among existing technologies. It can build a virtual model in the computer that is exactly the same as the real building. In this model, the structure, equipment, and materials of the building should be corresponding, which is a digital building blueprint. When BIM technology is used in large-scale steel structure construction equipment, during construction, the BIM model can be used to simulate the construction process, discover possible problems in advance, and optimize the construction plan. It can also monitor the construction progress and quality in real time to ensure that everything goes according to plan. At the same time, the BIM model can also interact with the construction equipment, and the BIM model can be used to control the operation of the construction equipment to ensure that they complete the task accurately and efficiently. In this way, construction becomes faster, more accurate, and safer.

[0003] However, in the prior art, such large-scale steel structure construction devices based on BIM technology have the following disadvantages when in use: when such devices in the prior art are in use, the lifting device has a single function and can only perform simple lifting work, and the device is prone to shaking after being lifted, which is inconvenient during assembly. Even without manual operation, the BIM model is used to match the construction device for work, and it is time-consuming and labor-intensive to assemble and dock. At the same time, it is troublesome to unhook the device, especially when it is assembled at a high place, and it is troublesome to unhook and cannot meet the requirements of high-efficiency assembly. Therefore, it is necessary to improve a large-scale steel structure construction device based on BIM technology to address this problem. Summary of the invention

The outer surface of the cross mounting plate is movably interspersed with movable plates all around. The lower end of the cross mounting plate is fixedly provided with an electric push rod, and the end of the electric push rod is fixedly connected to the movable plate. The lower end of the movable plate is fixedly provided with a second electric hoist, and the outer surface of the second electric hoist is wrapped with a second lifting rope. The stabilizing mechanism can be used to pull, tension and fix the steel frame from all sides as needed, thereby ensuring the stability of the entire steel frame during lifting, which can facilitate the subsequent alignment, lifting and assembly of large steel structure building assemblies in conjunction with BIM technology.

[0008] Preferably, the lower ends of the second lifting rope and the first lifting rope are both provided with a hook mechanism for convenient unhooking, the hook mechanism includes a fixed block, an annular hook, a limit groove, and a limit block.

[0015] 1. During lifting, the present invention can drive the steel structure to move to the target position of the assembly part through the rotation of the rotating table and the extension and retraction of the boom. At this time, it is only roughly positioned. At this time, there must be a certain deviation between the threaded hole of the steel structure and the predetermined installation position angle. At this time, the first motor and the reducer can drive the cross mounting plate to rotate slowly, so that the steel frame can be rotated according to the lifting, so that the steel frame can be easily aligned.

[0017] 3. When the present invention is used, the second motor drives the gear to rotate, so that the gear and the latch can drive the rotating ring to rotate, so that the steel frame to be assembled can be lifted by the annular hook. After the assembly is completed, compared with the traditional hook, the device can automatically and quickly unhook, so that the annular hook can be quickly separated from the steel frame, so that the next lifting work can be conveniently and quickly carried out.

[0018] 4. When the present invention is used, the camera can conveniently shoot the assembly picture obliquely downward, so that the staff can clearly observe the assembly situation at a low position, which can further facilitate the subsequent assembly work.

[0037] Working principle: When using this device, this device can better match BIM technology to carry out the hoisting work of large steel structure building assemblies. This device can lift the steel structure to be assembled like the crane in the prior art through the first electric hoist 8, the first hoisting rope 9 and the hook mechanism. During lifting, the steel structure can be driven to move to the target position of the assembly part through the rotation of the rotating table and the extension of the boom 3. At this time, it is only roughly positioned. At this time, there must be a certain deviation between the threaded hole of the steel structure and the predetermined installation position angle.
