Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a special device for high-altitude protection. Background Technology

[0002] Work exceeding 2 meters above the installation height reference plane is considered high-altitude work. To ensure the safety of construction workers, safety belts must be worn when working at heights, and the belt should be attached high and used low. "High attachment, low use" means that the safety belt should be attached above where the worker is standing, and the worker's work area should be below the attachment point. However, in reality, during steel structure construction, when installing secondary beams and purlins in I-beam installation environments, safety belts often lack attachment points, or the attachment points are below the worker's position, failing to adhere to the "high attachment, low use" principle. This poses a safety hazard and cannot guarantee the safety of construction workers.

[0003] The invention patent with publication number CN 109847227 A discloses a safety belt attachment point fixing device for high-altitude operations, including a fixed attachment point device, an attachment point ring fixedly installed on the fixed attachment point device, an insulating rope connected to the attachment point ring via an upper hook, a lower attachment ring installed at the other end of the insulating rope, and a fall arrestor and a safety belt hook sequentially installed at the lower end of the lower attachment ring. This device can provide a safety belt attachment point for high-altitude operations and achieve high attachment and low use. However, one end of the device is only fixed by a fastening bolt, which is not strong and poses a safety hazard. In addition, the integral structure also has the problem of inconvenience in use.

[0004] Utility model patent CN 214996230 U discloses a safety belt movable attachment device for steel structure workshops. The device includes a movable attachment unit comprising a vertical plate, an upper horizontal plate, and a lower horizontal plate. One end of the upper horizontal plate and one end of the lower horizontal plate are connected to the side of the vertical plate. An H-shaped steel beam is placed between the upper and lower horizontal plates. The movable attachment unit can move along the length of the H-shaped steel beam. The vertical plate has safety belt hanging holes. The lower end face of the upper horizontal plate has two first damping grooves. The top of the H-shaped steel beam is placed within and slidably connected to the first damping grooves. This attachment device allows construction workers to move freely within the working area. However, because the distance between the damping grooves is fixed, the specifications of the H-shaped steel beam are very important, limiting the applicability of this device. Utility Model Content
