Abstract
The invention discloses a tower of a wind driven generator. The tower comprises at least two tower tubes and a base plate. The tower tubes are abutted in the sleeving manner. The base plate is arranged under a base tower drum. Bosses are arranged on the lower portion of the upper tower drum, the upper portion of the lower tower drum and the upper portion of the base plate and embedded with one another. The tower tubes as well as the tower tubes and the base plate are all abutted in the sleeving manner, then clamped through the bosses and fastened by bolts. According to the arrangement, the tower is segmentally assembled by the standard tower tubes, production processes are simplified, damage and deformation caused by the oversize tower tubes rarely occur during conveying, the problem that the tower is too long to be conveniently conveyed is solved, hoisting and mounting difficulty of the heavy tower tubes is lowered, production cost is reduced, and production efficiency is increased.
Description
Technical field
The present invention relates to technical field of wind power generation.
Background technique
Along with wind power generating set single-machine capacity constantly increases, the technical requirements of wind turbine tower is also progressively being improved, mostly adopt the wind-driven generator tower frame of whole in prior art, make the aspects such as the processing of wind-driven generator tower frame, installation, maintenance, dismounting and transport very inconvenient.For above problem, if adopt standardization tower cylinder sectional pylon technology, the installation process of wind-driven generator tower frame greatly can be simplified.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wind-driven generator tower frame, and it adopts split-type structural, and pylon is resolved into multiple module, makes modular tower cylinder have convenient transportation, the feature that easy to assembly, installation efficiency is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of wind-driven generator tower frame, comprise tower cylinder and base disk, described pylon is at least with the docking of two tower jacket casing dresses, described base disk is positioned at below bottom tower cylinder, in the bottom of upper strata tower cylinder, the top of lower floor's tower cylinder and base disk top is respectively equipped with the boss that can embed mutually, all suit docking and all clamped by boss and use bolton again between tower cylinder and between tower cylinder and chassis.
Above-mentioned wind-driven generator tower frame, described boss comprises cavity boss and internal layer boss; The periphery of described tower cylinder bottom is provided with symmetrical cavity boss, and the periphery on tower cylinder top is provided with the internal layer boss of symmetrical embedded cavity boss, and the tower cylinder more than internal layer boss is provided with shoulder; The shoulder of bottom tower cylinder inserts the inwall of upper column cylinder, is bolted connection in the cavity boss that the internal layer boss of bottom tower cylinder embeds upper column cylinder; Described base disk is provided with vertical tube, and described vertical tube periphery is provided with symmetrical internal layer boss, is provided with shoulder on vertical tube top, and the shoulder of vertical tube inserts the inwall of bottom tower cylinder, is bolted connection in the cavity boss that the internal layer boss of vertical tube embeds bottom tower cylinder.
Above-mentioned wind-driven generator tower frame, is also provided with angle bar pressure ring on described base disk, and described angle bar pressure ring is provided with the earth stud through base disk.
Above-mentioned wind-driven generator tower frame, described pylon also comprises the foot plate that can hang on bolt, and described foot plate is provided with slotted eye, and described bolt is provided with double-deck nut, and foot plate is hung between outer nut and the hexagon end head of bolt by its slotted eye.
The beneficial effect of technique scheme is adopted to be, the present invention's standardization tower cylinder module sectional pylon, simplify product processes, decrease the phenomenon losing distortion in transport because tower cylinder is excessive, solve the problem of the long inconvenience transport of pylon, reduce because of the excessive difficulty of not easily lifting by crane installation of tower cylinder quality, cost of production can be reduced and enhance productivity.
