CAGE FOR CARRYING MAINTENANCE PERSONNEL TO OVERHAUL EXTERNAL WALL
Document Type and Number:
WIPO Patent Application WO/2019/136571
Kind Code:
A1
Abstract:
A cage for carrying a maintenance personnel to overhaul an external wall, comprising a cage body (10) hang by a rope (12) to be suspended at an end of a wall (81). An accommodating chamber (13) for carrying the maintenance personnel is formed in the cage body (10). Two pairs of rollers (20a, 20b) in contact with the wall (81) in rolling fashion are freely and pivotally provided at both ends of the cage body (10) toward the wall (81), respectively. A space is formed between the cage body (10) and the wall (81) by means of the two pairs of rollers (20a, 20b). A pair of foldable negative-pressure suckers (30) is provided at both ends of the cage body (10) toward the wall (81). The negative-pressure suckers (30) are located between the two pairs of rollers (20a, 20b) at intervals. The cage body (10) is positioned by sucking the negative-pressure suckers (30) to the wall (81). In this way, the problems that the conventional suspension type maintenance platform for overhauling the external wall of a building is prone to shaking, instability and lack of safety in the high air are solved.
