Description
Technical field
The utility model belongs to crane facility, relates to a kind of Shears device of floating crane.Be specially adapted to large-scale floating crane.
Background technology
As everyone knows, its floating crane is the installation that is mainly used in coastal waters or inland river, the key equipment of salvaging relief and the training of channel.Current, along with advancing of economic and science and technology, the type of its floating crane is also increasing.Can't be by the coastal bridge of having built up with the inland river, the camp site of can not opening the navigation or air flight smoothly due to the Shears superelevation as the large-scale floating crane that occurs on market.Shown in the floating crane Shears structure (accompanying drawing 5) of its common use, its keystone configuration 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 the jib head by the luffing range of cantilever support system.The moment that leans forward that jib and goods produce all is converted into luffing power, mainly by the 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; usually the crane arm support of use can be placed on the rest stand of hull or satisfy headway on deck plane; in case due to superelevation, just can't satisfy the navigation limit for height requirement of some bridges when Shears.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 usually; 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 the large-sized structural parts repeated removal, install and to be difficult to guarantee equipment performance, stay potential safety hazard.Above-mentioned large-scale floating crane, although can the elevation angle can be reduced at jib under off working state, regular situation can be down to the jib elevation angle 0 °, to reduce the headway of complete machine; But but also can't realize the navigation condition of bridge due to self Shears superelevation.Therefore the shortcoming and defect part that exists for above-mentioned technology, the Shears device of researching and developing a kind of large-scale floating crane that is put into newly is very necessary.
Summary of the invention
The utility model is intended to the shortcoming and defect that exists in above-mentioned technology, grasping characteristic and the holding capacity distribution of large-scale floating crane Shears bearing load are being set out, namely when salvaging, the Shears front strut is in operating angle, mainly bears pressure load; The Shears back stay is stretching, main bearing tension load; During navigation, adopt collapsible back stay to realize sequentially folding, realize the Shears front strut is rotated to fall being purpose, and a kind of Shears device of floating crane is provided; This Shears device is not only reasonable in design; simple and practical; both pass through the folding of Shears back stay, by Shears being fallen and rise with winding mechanism lay winding wire ropes mode, realized large-scale floating crane in the coastal waters or the clog-free smooth navigation in inland river again; and it is high to have efficient; simple to operate, easy to maintenance, small investment; the characteristics such as cost is low, and safety of operation and use are very convenient.
The purpose of this utility model is to adopt following technical scheme to realize: the collapsible Shears device of described floating crane, comprise front strut, back stay, turntable and jib, it is characterized in that: its Shears adopts the folded form Shears, described folded form Shears is hinged in the bottom of an end of turntable and collapsible back stay, described collapsible back stay is comprised of first arm-tie, link span, bearing pin and second arm-tie, the top of its collapsible back stay is hinged on connecting panel, and the angle of its collapsible back stay and turntable is the β angle; The Shears draw off gear that the other end installing of described turntable is comprised of support, running block, steel rope, fixed pulley group and winding mechanism; The bottom of described support is connected on turntable; The top of its front strut is connected on connecting panel, and its front strut bottom and turntable front end are hinged, and the angle of described front strut and turntable is the α angle, installs running block on described front strut; Its top of the trellis installing fixed pulley group, described wirerope-winding forms steel cable winding system between running block, fixed pulley group, winding mechanism; Its jib and turntable front end are hinged, and its jib top is connected on the head of luffing range of cantilever support system, and the afterbody of its luffing range of cantilever support system is connected with front strut; Be wound around by the retractable of winding mechanism to steel rope, realize falling and located rise in the location of folded form Shears.
Principle of the present utility model and characteristics are described below:
(first), the utility model are the force distributions that bears of fully having analyzed load character that the floating crane Shears bears and each constituent elements, and the Shears back stay is designed to collapsible pulling plate structure.During salvor work, the Shears front strut is in operating angle, mainly bears pressure load; The collapsible back stay of Shears is stretching, main bearing tension load.During the salvor navigation, its collapsible back stay constituent elements is sequentially folding, and the rotation of Shears front strut was fallen.
(second), Foldable type Shears coordinate winding mechanism to realize falling and the function that rises, and have both satisfied the serviceability of hoisting crane, satisfied again the requirement that Shears integral body was fallen, and the similar device of function that requires is had certain commonality;
(the third), Shears was fallen and rise by winding mechanism lay winding wire ropes mode, simple to operate, easy to maintenance; Avoided dropping into larger fund and human cost, safety, completed the Shears location efficiently and fell and the function of locating rise.
The comprehensive above technical scheme of taking realizes the purpose of this utility model.
Therefore; the utility model is not only reasonable in design, and is simple and practical, both folding by the Shears back stay; again by Shears being fallen and rose with winding mechanism lay winding wire ropes mode; realize large-scale floating crane in the coastal waters or the clog-free smooth navigation in inland river, and it is high to have efficient, simple to operate; easy to maintenance; small investment, cost is low, safety of operation and use the characteristics such as very convenient.
