Abstract
The invention discloses connection mechanisms for integrally mounting offshore fans in the technical field of mounting equipment of offshore wind generating sets, which is distributed on offshore fan mounting equipment in an arrangement mode that two mechanisms are arranged on the left and two mechanisms are arranged on the right symmetrically. Each connection mechanism comprises a tenon assembly and a groove support which is rotatably connected with the tenon assembly correspondingly, wherein the tenon assembly and the groove support are in welding connection with a balance beam main body and a tower frame respectively. By the mechanisms, a balance beam and the tower frame which are used for integrally mounting the offshore fans are fixed rigidly; and the mechanisms are convenient to disassemble.
Description
Technical field
What the present invention relates to is a kind of device of offshore wind generating technical group field, specifically is a kind of bindiny mechanism that is used for the offshore wind turbine integral installation.
Background technique
The integrated type method of installing that blower fan integral body is installed ship handling to blower foundation from wind-powered electricity generation has become the new trend that offshore wind turbine is installed gradually.But wind power generating set is in land assembly unit, marine transportation and integral installation process, because its center of gravity is high, and problem such as lay particular stress on the heart easily or topple.The effect that overcomes the above problems has been played in the setting that is installed on the equalizer bar on pylon top.
Retrieval through to the existing technology document is found; The Chinese patent document number is: CN201615031; Name is called the patent of " the offshore wind generating group is installed and used the equalizer bar structure "; This mechanism comprises the equalizer bar body of the right and left symmetry, and this equalizer bar body middle part is provided with one and is convenient to the balance support body and is installed in the hollow suit portion on the blower fan tower barrel, is provided with the system of holding tightly in said hollow suit portion.This equalizer bar structure has guaranteed the situation that wind power generating set can not occur toppling in land spelling, marine transportation and integral installation process.Can know that according to structural mechanics knowledge for the hinged beam in two ends, its suffered maximal bending moment is the twice of the beam that all rigidly fixes of two ends.For reducing the suffered load of equalizer bar, the connection between equalizer bar and the pylon should be adopted and be rigidly connected, and need guarantee also simultaneously that this is rigidly connected and can be removed when mounted.
Summary of the invention
The present invention is directed to the above-mentioned deficiency that existing technology exists, a kind of bindiny mechanism that is used for the offshore wind turbine integral installation is provided, this structure can make between equalizer bar and the pylon of offshore wind turbine integral installation and rigidly fix, and convenient disassembly.
The present invention realizes through following technological scheme; The present invention is distributed on the offshore wind turbine erection unit with the right and left symmetry, each arrangement mode of two of every limit; This bindiny mechanism comprises: tenon assembly and the corresponding groove bearing that is rotationally connected, wherein: tenon assembly and groove bearing are welded to connect with equalizer bar main body and pylon respectively.
Described tenon assembly is made up of equalizer bar contiguous block and tenon, and wherein: tenon is arranged at the lower end of equalizer bar contiguous block; The shape that corresponding described groove bearing is provided with tongue-and-groove and tongue-and-groove and tenon is suitable.
Described tenon is a turbination.
Described equalizer bar contiguous block is provided with identical fixed hole with described groove bearing, and described flexible connection realizes that through fixed hole when tenon grafting corresponding groove, two fixed holes are in coaxial position.
When the groove of the tenon grafting corresponding groove bearing of tenon assembly, and the fixed hole of the fixed hole of corresponding tenon assembly and groove bearing is connected in series when fastening, and equalizer bar and pylon are fastenedly connected.
Effect of the present invention is: the present invention has guaranteed to be used for to rigidly fix between equalizer bar and the pylon of offshore wind turbine integral installation, can be unloaded easily when needed simultaneously.The turbination design of tenon makes tenon pass in and out groove more easily.The cost of equalizer bar has been practiced thrift in this design, has improved the efficient of cross-over beam loading and unloading.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, present embodiment provided detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technological scheme of the present invention.
As shown in Figure 1; The present invention; The bindiny mechanism 1 that promptly is used for the offshore wind turbine integral installation is the mechanism in order to realize that equalizer bar 2 is connected with pylon 3; Bindiny mechanism 1 is installed on pylon 3 tops, and equalizer bar 2 is used to hold tightly blower fan tower barrel 4, through being distributed on the offshore wind turbine erection unit and being achieved with the right and left symmetry, each arrangement mode of two of every limit.
Like Fig. 2-shown in Figure 4, the present embodiment device comprises: tenon assembly 5 and the corresponding groove bearing 8 that is rotationally connected, wherein: tenon assembly 5, groove bearing 8 are welded to connect with equalizer bar 2 main bodys, pylon 3 respectively.
Described tenon assembly 5 is made up of equalizer bar contiguous block 11 and tenon 6, and wherein: tenon 6 is arranged at the lower end of equalizer bar contiguous block 11, and it is suitable that corresponding described groove bearing 8 is provided with the groove 7 of tenon 6 and groove bearing 8 of groove 7 and tenon assembly 5.
Described tenon 6 is the turbination structure.
Be respectively equipped with fixed hole 9,10 on described groove bearing 8 and the equalizer bar contiguous block 11, when tenon 6 grafting corresponding groove 7, two fixed holes are in coaxial position, realize being rotationally connected.
When the groove 7 of the tenon 6 grafting corresponding groove bearings 8 of tenon assembly 5, and fixed hole 9 serial connections of the fixed hole 10 of corresponding tenon assembly 5 and groove bearing 8 are when fastening, and equalizer bar 2 is fastenedly connected with pylon 3.
This device carries out work in the following manner: when stable equilibrium beam 2, at first equalizer bar 2 is lifted to the pylon top, make tenon 6 aim at corresponding grooves 7.Slowly falling equalizer bar 2 again inserts in the groove 7 tenon 6.After tenon 6 docks with groove 7 and finishes, be connected in series the fixed hole 10 of tenon assembly 5 and the fixed hole 9 of groove bearing 8 fastening.When unloading equalizer bar 2, at first unclamp fixed hole 9 and 10, again equalizer bar 2 is slowly sling, make tenon 6 leave groove 7, at last equalizer bar 2 is hung pylon 3.
