Abstract

This invention relates to a cage device for high-altitude operations on top of steel pipe piles, belonging to the technical field of high-altitude work equipment. It aims to solve technical problems such as limited working space, difficulty in personnel access, restricted machinery, and harsh working environments in high-altitude operations on top of steel pipe piles. The invention employs a frame-type cage welded from structural steel and steel plates, securely connected to the hanger via connecting seats and clamps. The support rod is designed with a multi-segment, adjustable structure to accommodate steel pipe piles of different diameters. Reinforcing bushings are installed inside the lifting lugs to ensure the safety of the connection between the sling and the hanger. Anti-slip pads are installed at one end of the support rod to increase friction. The main purpose of this invention is to improve the safety of high-altitude operations on top of steel pipe piles, accelerate construction efficiency, and save costs. Through a stable working platform design, it effectively reduces the impact of wind speed on operations, improving construction safety and convenience. It can be used in conjunction with various cranes, demonstrating strong practicality, high application value, and good economic and social benefits.
