Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power tower, in particular to a tower support seat with adjustable fulcrum. BACKGROUND

[0002] The wind power tower is the tower of wind power generation, which mainly plays a supporting role in the wind turbine and absorbs the vibration of the turbine.

[0003] The existing wind power tower has different requirements when stacking according to the thickness of the tower wall. For example, the structure of the tower section with thinner wall is prone to deformation, so when stacking, the two sides need to be protected to prevent the top from collapsing; for the tower section with thicker wall, although the top will not collapse, the middle position between the two support points may be broken when stacking due to the large mass. Obviously, the traditional support base cannot be applied to tower sections with different wall thicknesses.

[0004] In view of the problems existing in the prior art, the present application aims to design a tower support seat with adjustable fulcrum. SUMMARY

[0005] In view of the problems existing in the prior art, the present application provides a tower support seat with adjustable fulcrum, which can effectively solve the problems existing in the prior art.

[0006] The technical scheme of the present application is as follows:

[0007] A tower support seat with adjustable fulcrum, comprising a guide rail and a plurality of movable devices on the guide rail, the tower support mechanism comprises two support platforms, the bottom of each support platform is provided with a guide wheel, and the support platform is movable on the guide rail through the cooperation of the guide wheel and the movable device; a roller support seat is symmetrically arranged on each support platform, and a corresponding support roller is rotatably arranged on the roller support seat; two tower deformation prevention mechanisms are symmetrically arranged between the two support platforms of the tower support mechanism, each tower deformation prevention mechanism comprises two tower side support plates, and the inner side of each tower side support plate is in arc shape; the relatively narrow ends of the two tower side support plates are hingedly connected to each other, and the relatively wide ends of the two tower side support plates are respectively hingedly connected to the side surfaces of the corresponding support platforms; a through hole and a threaded hole are respectively arranged at the middle positions of the front and rear support platforms in the same tower support mechanism, a connecting rod is connected between the through hole and the threaded hole, the front end of the connecting rod is provided in a threaded shape, and a motor for driving the connecting rod to rotate is arranged on the support platform at the rear end of the connecting rod.

[0008] Further, the relatively wide end of the tower side support plate and the side of the support platform are both provided with a plurality of corresponding shaft sleeves at equal intervals, a rotating shaft is arranged through the shaft sleeves between the tower side support plate and the support platform, limit blocks are arranged at both ends of the rotating shaft, and the tower side support plate is hinged to the side of the support platform through the shaft sleeves and the rotating shaft.

[0009] Further, the support platform is provided with a limit baffle below the corresponding shaft sleeve.

[0010] Advantages of the present application:

[0011] The present application not only has a simple structure, but also can adjust the position of the supporting point according to different requirements, so as to adapt to the tower segments with different tower wall thicknesses. When supporting the tower segment with a thin tower wall, the two support platforms can be driven to approach each other by the motor, so that the two tower side support plates of the tower cylinder anti-deformation mechanism are arched upward to protect the outer wall of the tower segment and prevent it from deforming. When supporting the tower segment with a thick tower wall, the two support platforms are driven to move away from each other, so that the interval distance of each supporting point is not too long when supporting the tower segment, and the stress distribution of the tower segment is more uniform.
