Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction equipment, and particularly relates to a turning device for steel pipe arch segments. Background Art

[0002] Arch bridges have a long history in bridge construction. In the early days, most arch bridges were stone bridges. With the progress of society, steel arch bridges have been increasingly widely used. For long-span arch bridges, they are generally composed of multiple steel pipe arch segments. Before installation, the steel pipe arch segments are generally horizontal and need to be turned over.

[0003] In the prior art, the main method for turning over steel pipe arch segments is to use a floating crane to lift the steel pipe arch segment and turn it over in the air. Although this method can turn over the steel pipe arch segment, the use of a floating crane requires a large investment in equipment and high operating costs. Summary of the Invention

Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0037] The embodiments of the present invention provide a turnover device for steel pipe arch segments, which can solve the technical problem of the high use cost of existing construction equipment.

[0038] See Figure 1 and Figure 2 As shown, a turnover device for steel pipe arch segments includes: a plurality of fixed components 1, two groups of lifting components and a plurality of tension rope devices 3.

Two lifting components are respectively used to lift the two ends of the steel pipe arch segment 6 to be turned over. Each lifting component includes multiple pulley components 2, and all the pulley components 2 are connected to all the fixing components 1 in one-to-one correspondence. Multiple tension rope devices 3 are fixedly arranged on one side of the pulley components 2 and correspond to all the pulley components 2 one by one. The tension rope 31 of each tension rope device 3 is passed through the corresponding pulley component 2. In the embodiment of the present invention, the pulley component 2 of the turning-over device of the steel pipe arch segment is four, and the corresponding fixing component 1 and tension rope device 3 are also four.

The whole device has a simple structure, replaces the existing floating crane, and has a low use cost. Moreover, the turning-over device of the steel pipe arch segment in the embodiment of the present invention can be flexibly arranged and installed according to the construction needs, and is convenient to use.
