Abstract
A crane adapted for the erection of elongated bodies, preferably wind turbines, is attached to the same foundation which is used for the wind turbine. The crane comprises a jib which may be displaced forwards and backwards. The cap and the blades of the wind turbine are thereby hoisted to the top of the wind turbine tower once this has been erected. The crane is mounted on the same foundation. Bearing pedestals for seating the jib and anchoring straps for the attachment of double acting lifting and lowering devices are connected to the foundation, this foundation being additionally provided with an anchoring base for the wind turbine tower. The crane is of particular advantage for the erection of wind turbines in regions where it is difficult and costly to bring in a mobile crane for the erection of tall wind turbines or in case it is difficult to use a stationary crane in view of the anchoring and the support required for such cranes. Floating or wheeled mobile cranes need a large counterweight while stationary cranes according to the prior art require a solid anchoring at a great distance from the wind turbine foundation and put great demands to the steadiness of the support.
Description
The present invention relates to longitudinal bodies is erected at crane on the vertical position, this crane comprises can be around the boom of the clutch shaft bearing inclination with an axis that horizontally rotates, described clutch shaft bearing is arranged on the boom bottom that links to each other with a bearing surface, and at least one second bearing, described second bearing is arranged on also link to each other with bearing surface one two moving ascending, descending mechanism bottom, and the top of described ascending, descending mechanism is fixed on the boom.
The invention still further relates to by crane and erect a kind of base and the method that longitudinal bodies uses.
Towering wind turbine, for example, portion highly reaches 50 meters wind turbine to the wind turbine blade hub, normally erects by crane movably, erects by helicopter in the country of impassabitity.The energy is obtained in order to make little local community in certain areas in the world, needs vertical wind turbine, and at this moment movably crane often can not achieve the goal owing to abominable, narrow path.Can use helicopter in this case, but this is very expensive method, if particularly road is far.At sea the wind turbine of Shu Liing is usually by movably Floating Crane setting.
Therefore, in this case, can only lower low performance wind turbine be installed by truck crane and small-sized removable crane so far, therefore must vertical a large amount of wind turbine.As substituting of mobile job crane, also can use the crane that firmly fixes on the ground.
DE2,602,745 have described a kind of crane that is used to lift by crane and erect elongate objects, and this crane comprises first pair of boom, a cross bar and second pair of boom that extends from the upper end of one of first pair of boom.This crane is articulated in a base, and after crane installed, the latter was fixed by a pair of chain that stretches to first pair of boom from base.Can second pair the slinging elongate objects of boom it be erected thereafter.
Disclosed crane has some defectives in above-mentioned file.At first, the principle of this crane is longitudinal bodies upwards transporting between second pair of boom, because crane is than microscler low body.Therefore, after having erect, longitudinal bodies can not again other part be winched to above the longitudinal bodies.In addition, be necessary for crane and set up an independently base.
For the known crane or the miscellaneous equipment of the boom hoisting that constitutes longitudinal bodies such as wind turbine, flagpole or phone post, be necessary for crane or lifting appliance and set up independently a base or a fixed point independently.
This crane or lifting appliance can be known clearly and be read GB1, and 270,205, GB2,115,368, DE2,255,713, FR1,213,060, FR3,075,866, EP0,169,104, SE152,198 or above-mentioned DE2,602,745.
The basic defect of disclosed crane or lifting appliance is in the above-mentioned file, is necessary for to absorb tension force and set up at least one point, and this point is often away from the place of the longitudinal bodies of preparing to erect.This just has very high requirement to the rigidity and the fastness of supporting member, so that set up to absorb the point of tension force on this supporting member, this also has very high requirement at that point anchor device itself.If rigidity at that point, fastness and anchoring are not enough, in the setting process, longitudinal bodies may be suddenly, have warning message ground not fall earthward, thereby cause the catastrophic effect to equipment and personnel.Particularly when preparing to be erected at longitudinal bodies on sea or the swamp land, erectting large-sized object can occasion a great deal of trouble.
The purpose of this invention is to provide a kind of crane, a kind of base and a kind of method, except erectting longitudinal bodies and after erectting longitudinal bodies, other part can being sling to the top of longitudinal bodies or part are highly sentenced, it does not rely on the independent seats of establishing for crane, the danger that longitudinal bodies does not plunk down in longitudinal bodies setting process yet.
Above-mentioned purpose is to realize by the crane with following characteristics: support and the base of formation longitudinal bodies, the clutch shaft bearing of crane is anchored on the base by first anchor device, first anchor device of described clutch shaft bearing be arranged on the longitudinal bodies installing zone and the base opposed edges district that looks with respect to first anchor device between, at least one of crane second bearing uses at least one second anchor device to be anchored on the base, and described second anchor device is arranged in the side from first anchor device to described fringe area and leaves distance of first anchor device in the opposite direction.
This crane is specially adapted to and mainly develops for erectting tall and big wind turbine.But, also can be used for erectting other longitudinal bodies such as flagpole, phone post or other object according to crane of the present invention.In addition, this crane can be used for being erected at the longitudinal bodies that sea and land have a base.Hereinafter, this crane will be described at erectting wind turbine, and still, this explanation does not limit the application of crane.
Use the base of the base of wind turbine according to crane of the present invention as oneself.This has some advantages.The base of wind turbine often rigidity is fine, and is very firm, that is, it is anchored at well on the ground or on the sea bed, the employed material of base is also very firm, because base is wanted to bear very big power when wind turbine is worked.Therefore, base is that the anchoring crane can rigidity or fastness deficiency yet.In addition, on the water or in the situation of wheeled removable crane counterweight must be set, and crane of the present invention needn't be provided with counterweight.
For static crane or lifting appliance, be according to another advantage of crane of the present invention, do not need to provide place away from wind turbine, that is, wind turbine base a bit or a plurality of point.In wind turbine setting process, the basic load power by the anchoring position of above-mentioned first and second anchor devices that reaches crane is pressure.Base can easily absorb this pressure load force, and is less demanding to the anchoring on base according to crane of the present invention, and this point is different from by the crane of the fixing prior art of tension force or the anchoring situation of lifting appliance.
Also make the tall and big powerful wind turbine that has of installation become possibility according to crane of the present invention, thereby can reduce the quantity of the wind turbine that needs installation.The advantage of tall and big wind turbine is to reduce cost of electricity-generating, thus corresponding reduction electricity price.
Than the wind turbine tower height that will erect, this makes it wind turbine cap and blade can be winched to cat head after holding up wind turbine tower according to crane of the present invention.This obviously is impossible in the situation of the crane lower than tower.This crane mainly is to be used to erect 30 to 50 meters even higher wind turbine.Past, this required the use ability to approach 350 tons very big removable crane.
In order to finish the purpose that wind turbine cap and blade is winched to cat head, crane must be suitable for forward and backward tilting to makes crane loading mechanism be positioned at forward and backward side of the wind turbine tower that is erected and the position directly over it not.Wind turbine cap and wind turbine blade will be placed on column foot the place ahead or rear, and the lifting appliance of derricking gear such as suspension hook etc. will be placed on the place ahead or the rear of tower, and its position is suitable for wind turbine cap and wind turbine blade are winched to cat head.When wind turbine cap and blade being winched to the height that needs, crane will tilt so that respectively relative respectively tower of wind turbine cap and blade and wind turbine cap are moved horizontally to the position that place.
Jiang Ta erect and with wind turbine cap and blade installation after on the tower, generally just no longer needed crane.Crane is reduced to boom along ground or the position of extending, sea, pull down crane from base, and pull down bearing.Crane can be transferred to another wind turbine base then, connect and erect, can prepare to erect another wind turbine.
The load that crane with above-mentioned feature can guarantee to be added on the base distributes with possible best mode, need not to be provided with the other discharge mechanism of tension force or pressure with base spaced apartly, and this static crane and lifting appliance to other is essential, also need not to use counterweight in addition, and this is necessary concerning removable crane.
