Description

Technical Field

[0001] The utility model belongs to the field of building construction technology safety, and specifically relates to a pull-out type protection integrated device for a foldable unloading platform. Background Art

[0002] Unloading platforms are temporary operating platforms and operating racks often set up at construction sites, generally used for material turnover. Unloading platforms are divided into mobile unloading platforms, floor-standing unloading platforms, and cantilever unloading platforms. As for cantilever unloading platforms, in order to prevent construction workers from falling during operation and materials from scattering outside the platform during transportation, causing injuries from falling from high altitudes, safety protection nets will be set up around the platform. This protection method has the following disadvantages in installation, disassembly, and transportation:

[0003] 1. The splicing of protective devices is complicated and difficult, and most of them are installed by welding steel pipes. Multiple welding causes great damage to the structure;

[0004] 2. During disassembly, due to the large welding area, disassembly takes a long time;

[0005] 3. It occupies a large area during storage and transportation. When used in the short term, the above-mentioned protective device is difficult to store and transport on site. The three sides are rigidly connected, which is not easy to disassemble and occupies a large area during storage. The area for placing construction materials on site may be occupied. When transporting and reusing, the transportation cost, installation and disassembly labor cost will increase due to repeated installation and disassembly. At the same time, repeated welding will damage the structure of the unloading platform itself, requiring additional maintenance costs. Utility Model Content
