Description
Technical field
The present invention relates to a kind of Shears system, relate in particular to the Shears system that is applicable to ten thousand tons and ten thousand tons above heavy floating full-rotary cranes.
Background technology
Hoisting crane is many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, claims again crane, belongs to material carrying machine.Jib-type crane can circle and on idle job, be used for the work such as outdoor handling and installation.Shears is requisite member in jib-type crane, generally by upright pull bar, formed with the front strut that upper end is connected with pull bar, pull bar and front strut form " people " font, therefore title Shears, pulley assembly is installed on the top of Shears, Shears bottom arranges winch assembly, and copper rope is by the pulley assembly traction jib on Shears top.But the height of Shears is generally all higher, cause the volume of whole hoisting crane larger, be not easy to transportation and install.
Particularly, current, along with advancing of economic and science and technology, the type of floating crane is also increasing.The bridge that cannot build up by coastal and inland river due to Shears superelevation as the large-scale floating crane occurring on market (such as the Suez Canal etc.), the camp site of can not opening the navigation or air flight smoothly.Conventionally the keystone configuration of the floating crane Shears structure of use comprises front strut, back stay, jib and turntable, its front strut and back stay bottom-hinged or be welded on turntable, and both tops are generally and adopt integral solder or hinged; This integral solder easily causes stress to concentrate in the connection mode of one, causes parts impaired; The front end of its jib and turntable is hinged; Its Shears top is connected with jib head by luffing range of cantilever support system.The moment that leans forward that jib and goods produce is all converted into luffing power, mainly by Shears carrier of head.Along with the development of the more and more large-scale change of floating crane, scantling of structure also constantly increases.The front strut of Shears, back stay, jib are installed on rotating platform of crane; floating crane is when coastal or inland river navigation; conventionally the crane arm support of use can be placed on the rest stand of hull or meet headway on deck plane; once when Shears is due to superelevation, just cannot meet the navigation limit for height requirement of some bridges.Shears bearing load, the oad of its large-scale floating crane are all larger, and front strut back stay, turntable connection each other adopt welding or articulated form conventionally; As dismounting at sea, certainly will will be equipped with the auxiliary weight-lifting equipment in relatively large sea, be equipped with numerous personnel's co-operate again and just can complete, therefore whole process is very complicated, hand labor intensity large, waste time and energy, work efficiency is extremely low; And large-sized structural parts repeated removal, install and will to be difficult to assurance equipment performance, to leave potential safety hazard.
