A large-diameter steel pipe construction safety suspension device

Abstract

The invention discloses a large-diameter steel pipe construction safety suspension device, which includes a frame and a suspension rope system. The frame is installed on the upper nozzle of the steel pipe. The main walking wheel is installed on the pin shaft; the front and rear compression mechanisms that can be locked when the human body falls are respectively installed on the front and rear sides of the frame, the steel pipe is provided with a limit screw, and the outer wall of the steel pipe is fixed with a tension spring A tension spring is connected between the fixing part and the tension spring fixing part and the front compression mechanism. The suspension rope system includes a fixed wire rope and an adjustable wire rope. Connected, the other end of the fixed wire rope is connected with the front pressing mechanism, and the lower end of the adjustable wire rope is provided with a safety belt. The invention can roll along the steel pipe, can adjust the length of the steel wire rope, and can be automatically locked when falling to ensure the safety of construction personnel.

Description

technical field [0001] The invention relates to a construction safety device, in particular to a construction safety suspension device for large-diameter steel pipes. Background technique [0002] Existing steel pipes often need to be constructed at different heights during construction, installation of stiffening rings, welding or other construction. In particular, the construction of large-diameter (generally more than 6 meters in diameter) pressure steel pipe, the height is generally more than 3m, which belongs to high-altitude operation and poses a great safety hazard. Scaffolding or construction ladders are arranged on site. Since the safety belt cannot be hung, construction workers often fall during construction, causing accidents; even if simple scaffolding is used, workers need to move around the steel pipe during welding and cannot be fixed in one position. , often inflicting damage while walking. Therefore, how to design a safety suspension device suitable for su...

Problems solved by technology

Especially in the construction of large-diameter (generally more than 6 meters in diameter) pressure steel pipes, the height is generally more than 3 meters, which belongs to high-altitude operations, and there are great potential safety hazards

Scaffolding or construction ladders are arranged on the site. Since the safety belts cannot be suspended, construction workers often fall during construction, causing accidents. Even simple scaffolding is used, and because workers need to move around the steel pipe during welding, they cannot be fixed in one position. , tends to cause damage by stepping into the air while walking
