Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment used for reconstruction and expansion of interchange bridges on expressways, and more specifically, particularly relates to anti-falling hoisting equipment for interchange bridges. Background Art

[0002] An interchange is an intersection in which a spanning structure is set up to separate the intersecting roads in space, and the upper and lower roads are connected by ramps to facilitate the passage of turning vehicles. Interchanges can be divided into three types: partial interchanges, full interchanges and circular interchanges, depending on the crossing method and geometric shape of the traffic trajectory lines at the intersection. After the construction of highway interchange bridges, they need to be renovated and expanded as needed. When renovating and expanding highway interchange bridges, personnel are needed to carry out on-site construction, and a lifting platform is needed to assist in transporting personnel to a fixed height. Since the lifting platform is usually pulled by ropes, it is easy to shake during the ascent, so the lifting platform structure usually has an external structure.

[0003] Based on the above, most of the current lifting platform inlet and outlet locking structures are single, and are mostly locked by a single bolt. However, the single fixing method is prone to loosening of the locking structure and illegal unlocking by humans, which puts the personnel on the lifting platform in danger of falling.
