Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and in particular relates to a fixing device for lifting a factory door. Background Art

[0002] During the hoisting process of large factory doors, after the ground assembly is completed, the conventional method is to use a crane to hoist them. When using a crane to hoist, a lifting ring is often welded on the door leaf. After the door is adjusted into place by the lifting ring, the lifting ring is cut off. Although this method can solve the hoisting problem of the door, hoisting the door through the lifting ring will cause damage to the door due to its large size and weight. The lifting ring is a single-point force, and after the lifting ring is cut off, it will leave scars on the door, affecting the construction quality of the door. Therefore, a fixing device for hoisting the factory door is needed to solve this problem. Utility Model Content

[0004] Furthermore, the two first connecting plates are fixedly connected to the connecting rod via a limiting assembly, wherein the limiting assembly comprises a limiting plate, the limiting plate is fixedly sleeved on the connecting rod, and the limiting plate is fixedly connected to the first connecting plates via a plurality of studs.

[0005] Furthermore, the number of the studs is set to four, and the four studs are arranged on the limit plate in a circle with the connecting rod as the center.

[0006] Furthermore, the lifting ring is located in the middle of the fixing block and the limiting plate.

[0007] Furthermore, the lifting ring is configured to be U-shaped, with the closed end of the lifting ring facing upward and the open end of the lifting ring facing downward and fixed on the first connecting plate.

[0008] Furthermore, the number of the fixing holes on the fixing plate is set to six, and every three fixing holes are arranged in a row, and the two rows of fixing holes are respectively located at the upper and lower ends of the fixing plate.

[0009] Furthermore, both ends of the connecting rod are fixedly connected with second connecting plates, and the upper rear portions of the two second connecting plates are provided with connecting holes matching the lifting hooks.

[0010] The advantages of the utility model are: the utility model provides a fixing device for lifting a factory gate, which fixes the fixing device to the factory gate so that the factory gate and the lifting device form a whole. During the lifting process, the lifting point will not directly act on the door leaf of the gate, thereby avoiding damage to the gate caused by excessive force at the lifting point. At the same time, the gate and the fixing device connected by bolts are also easier to disassemble and can be recycled, which is convenient for construction personnel to quickly install and use, solving the problem that there is no suitable lifting point when lifting the steel structure factory building of the gate, and welding and cutting off the lifting ring are not only time-consuming and labor-intensive, but also inconvenient for installation, thereby reducing the installation efficiency.
