Description
Technical field
The utility model belongs to tower crane technical field more particularly to a kind of tower crane main rope rope supporting device.
Background technique
Tower crane, i.e. " derrick crane " abbreviation, also known as " tower crane ".It is for one of construction lifting equipment.With
Being increasing for skyscraper and Large Scale Construction Engineering, the demand to large-scale derrick crane also accordingly increases.Currently, some
The jib length of large-scale derrick crane has reached 80 meters, also, the biggest lifting capacity is also increasing, hoist rope
Diameter also overstriking therewith.In this way, it is excessive to lead to the problem of hoist rope sagging amount of deflection in tower crane zero load.Such as figure
Shown in 1, relative to a length of 80 meters of the tower crane of crane arm, the sagging amount of deflection H of maximum of hoist rope may reach 10 meters or more.
In this case, not only danger can be brought to construction；Withdrawing rope time when also will increase lifting reduces tower crane construction effect
Rate.
It is all often that more large-scale derrick cranes and other Architectural Equipments work at the same time, each other in Large Scale Construction Engineering
Between work range be overlapping.It is asked in order to avoid generating interference between each tower crane and between other Architectural Equipments or building
Topic, the conventional method of use is exactly to increase tower crane tower body height, this undoubtedly will increase equipment cost, meanwhile, it can also increase tower crane
The risk of running；It is constant in other factors if reducing the sagging amount of deflection of hoist rope using the method for increasing suspension hook weight
In the case where, and the biggest lifting capacity of tower crane will certainly be reduced.
