Description
Technical field
The invention belongs to hoisting rig, a kind of tower hoisting rig is particularly related to.
Background technology
With the emergence of wind-power electricity generation, substantial amounts of blower fan tower barrel needs handling, upset and installs, and for safe handling, steady upset, efficient installation, therefore must select the professional Current Collector Sleave for matching.
At present, wind-power tower special complete rigging is mainly lifted by crane with two leg riggings (matching somebody with somebody simple hanger in end), and there are the following problems for above-mentioned prior art：One is not perfectly flat steady upset, there is greater impact；Two are overturn as after vertical state, stationarity is poor when mounted, easily swings；Three is that 2 handlings have certain damage to tower drum flange；Four be single-piece hanger from great, cannot be installed by manpower.
The content of the invention
Multipoint hoisting, handling and the stable tower hoisting rig of installation are used it is an object of the invention to provide one kind.
Tower hoisting rig, including tower upper end suspender, tower lower end suspender, the upper hanger in the suspender of tower upper end are distributed in tower upper flange and use bolts assemblies, and the lower hanger in the suspender of tower lower end is fixed with tower lower flange using bolt；The hoisting rig also includes：
Upper hanger in A, tower upper end suspender is distributed on tower upper flange and uses bolts assemblies with it, and the lower hanger in the suspender of tower lower end is distributed in the first half with tower lower flange and uses bolt to fix with it；
B, described tower upper end suspender include the suspender belt, shackle, rotation hanger, pulley, hoist cable, shackle and the upper hanger that are from top to bottom sequentially connected, and tower lower end suspender includes the suspender belt, shackle and the lower hanger that are from top to bottom sequentially connected.
To realize the increase of hanger pitch-row scope, it is easy to the wildcard of hanger, to be adapted to the connection of different section towers (often covering tower typically has 3-5 to save), is easily installed, while reducing the quantity of hanger, is easy to reduce installation cost.Preferred structure design is that the fixing hole side in described lower hanger with tower lower flange is circular hole, and opposite side is slotted hole.
For the balance for realizing tower is lifted, mitigate the deadweight of hanger simultaneously, reduce the stress loading of tower wall, preferred structure design is, lower hanger is preferably distributed in the structure design form of tower lower flange surface and the multiple (even number) set with tower axisymmetrical, wherein it is more highly preferred to and just the frame mode with realization is, described lower hanger is four, it is distributed in tower lower flange surface and is set with tower axisymmetrical, one end of a wherein side sling is connected by buckle lower hanger, the other end of hoist cable is connected to the shackle with another lower hanger positioned at tower axis homonymy through pulley.
For further protection tower wall is unlikely to concentrate by larger stress, preferred structure design is that upper hanger, the fixing bolt outer surface of lower hanger are provided with support set.
To meet the balance of lifting, to realize steady handling, preferred structure design is that described pulley top uses rolling assembling with rotating lifting eardrum portion.The frame mode for being wherein more highly preferred to and being easily achieved is that an oscillating structural member is additionally provided between described pulley and rotation hanger, and the top of the oscillating structural member is connected with the bottom of rotation hanger, and the bottom of the oscillating structural member is connected with the upper end of pulley using bearing pin.
The present invention can coordinate handling using major-minor crane, convenient, flexible.The pulley supporting with tower upper end suspender, can not only swing, while can realize that 360 ° rotate freely, thus it is steady in tower switching process, reliable.Under tower Gravitative Loads, by the balanced action of pulley, tower vertically, is easily installed.Due to using multipoint hoisting, hanger deadweight is relatively light, general 20-30Kg, and one can install (traditional hanger typically conduct oneself with dignity ＞ 50Kg)；Stress simultaneously suffered by tower wall is smaller, can be effectively reduced the excessive possibility for causing to damage of tower wall stress.It is the structure design of slotted hole that lower hanger bottom bolts hole uses one side, increased pitch-row scope, increased the versatility of hanger, the connection of different section towers (often covering tower typically has 3-5 to save) can be adapted to, it is easily installed, reduces the quantity of hanger, reduces installation cost.
Specific embodiment
Tower hoisting rig, including tower upper end suspender, tower lower end suspender, the upper hanger in the suspender of tower upper end are distributed in tower upper flange and use bolts assemblies, and the lower hanger in the suspender of tower lower end is fixed with tower lower flange using bolt；The hoisting rig also includes：
Upper hanger in B, tower upper end suspender is distributed on tower upper flange and uses bolts assemblies with it, and the lower hanger in the suspender of tower lower end is distributed in the first half with tower lower flange and uses bolt to fix with it；
B, described tower upper end suspender include the suspender belt, shackle, rotation hanger, pulley, hoist cable, shackle and the upper hanger that are from top to bottom sequentially connected, and tower lower end suspender includes the suspender belt, shackle and the lower hanger that are from top to bottom sequentially connected.
To realize the increase of hanger pitch-row scope, it is easy to the wildcard of hanger, to be adapted to the connection of different section towers (often covering tower typically has 3-5 to save), is easily installed, while reducing the quantity of hanger, is easy to reduce installation cost.Preferred structure design is that the fixing hole side in described lower hanger with tower lower flange is circular hole, and opposite side is slotted hole.
For the balance for realizing tower is lifted, mitigate the deadweight of hanger simultaneously, reduce the stress loading of tower wall, preferred structure design is, lower hanger is preferably distributed in the structure design form of tower lower flange surface and the multiple (even number) set with tower axisymmetrical, wherein it is more highly preferred to and just the frame mode with realization is, described lower hanger is four, it is distributed in tower lower flange surface and is set with tower axisymmetrical, one end of a wherein side sling is connected by buckle lower hanger, the other end of hoist cable is connected to the shackle with another lower hanger positioned at tower axis homonymy through pulley.
For further protection tower wall is unlikely to concentrate by larger stress, preferred structure design is that upper hanger, the fixing bolt outer surface of lower hanger are provided with support set.
To meet the balance of lifting, to realize steady handling, preferred structure design is that described pulley top uses rolling assembling with rotating lifting eardrum portion.The frame mode for being wherein more highly preferred to and being easily achieved is that an oscillating structural member is additionally provided between described pulley and rotation hanger, and the top of the oscillating structural member is connected with the bottom of rotation hanger, and the bottom of the oscillating structural member is connected with the upper end of pulley using bearing pin.
