Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sliding safety net. Background Art

[0002] People have designed various types of safety nets to protect construction site workers from falling from heights. In the field of construction, there are many horizontal openings that run through different floors due to design requirements, such as elevator shafts, exhaust shafts, and open rooms. In order to prevent construction workers from falling from heights, horizontal nets or standardized protection should be set up according to the size of the horizontal openings. The horizontal net must be strong enough to protect the workers who fall into the openings. Usually, wooden boards or steel plates are used to cover the openings, or steel pipes are set around the openings and large mesh nets are laid. The above traditional methods require a lot of installation time and occupy storage space. Especially for extra-long horizontal openings, such as elevator shafts in large public buildings, there are greater safety hazards of falling from heights when setting up horizontal nets, and the installation takes a long time. Under certain special conditions, when the horizontal net protection needs to be opened frequently, the traditional protection method of moving or re-covering the openings is labor-intensive and time-consuming.

[0003] The Chinese utility model patent with application number 202221980882.9 discloses an electric sliding safety net device with adjustable size, including a safety flat net, a lifting eye bolt, a wire rope and a winch. The lifting eye bolt is fixed at a corner of the horizontal opening, and a wall connecting piece is provided at each of the other triangular parts of the horizontal opening. The wire rope passes through the lifting eye bolt and three wall connecting pieces in sequence and is tightened along the edge of the horizontal opening. The three sides of the safety flat net are connected to the wire rope through a quick ring buckle. The fourth side of the safety flat net is connected to a traction rope, and the other end of the traction rope is connected to the winch. The winch is set on one side of the horizontal opening where no quick ring buckle is provided. The patent improves the efficiency of erecting the horizontal opening protection net of the construction, reduces the labor intensity, is simple to use, easy to operate, saves time and effort, and reduces safety risks. However, the patent also has the following defects: one side of the safety flat net is electrically slid by a winch, but it is not fixed, and there is no support in the middle of the safety flat net, and the safety is poor.
