Description

TECHNICAL FIELD

[0001] The present application relates to a self-climbing basket, in particular a self-climbing basket for cable-stayed operation, and belongs to the technical field of baskets. BACKGROUND

[0002] Cable-stayed cables, also known as cables or stayed cables, are the main load-bearing components that directly transmit the weight of the main girder and deck of a cable-stayed bridge to the tower. The material of the cable-stayed cables of a cable-stayed bridge is usually steel cable, which can be composed of parallel steel wires, parallel steel cables, single steel cables, steel ropes, closed steel cables, or solid steel bars. As the cable-stayed cables are the main force mechanism of the cable-stayed bridge, they will inevitably be structurally damaged and force-degraded due to environmental erosion, material aging, long-term load effects, and other factors, which may cause corrosion or rupture of the steel wires of the cable-stayed cables, lead to a re-adjustment of the force of the cable-stayed cables, cause insecurity or even destruction of the entire structure, and affect the normal use of the cable-stayed bridge. Therefore, regular inspection and maintenance of the cable-stayed cables are important for ensuring the safety of the bridge structure. Currently, during the inspection and maintenance of the cable-stayed cables, a hoist or a climbing hoist is used to move the basket, and the workers complete the inspection and maintenance work in the basket.

[0003] Due to various factors such as environment and weather, there may be stubborn debris such as ice on the outer wall of the cable-stayed cables, which will hinder the movement of the hoist and affect the smooth climbing of the basket.

[0004] Therefore, a self-climbing basket for cable-stayed operation is proposed. SUMMARY
