specific Embodiment approach

[0036] The specific implementation is as follows: in the factory prefabrication, the Y-shaped connector 3 is screwed into the threaded hole of the bolt ball 2 embedded in the steel pipe 102, and in the field installation, the steel pipe 102 is threaded through high-strength bolts according to the pre-designed node positions. Connect and fix with the lower tower column 4, and ensure that it is firmly connected to the tower column 4. One end of the web rod 5 is connected to the end of the Y-shaped connector 3 support rod 302, and the steel pipe 102 is connected to the upper tower column 4 through high-strength bolts through high-strength bolts. Fixed and connected in sequence in this way to form a complete lattice-type concrete-filled steel tubular wind power tower. The whole construction process does not require on-site welding, but only needs to be connected by bolts, which is convenient for on-site installation, avoiding the residual stress and residual deformation caused by t...

Abstract

The invention relates to a connector for a lattice-type wind power tower, comprising: a sealing cavity, which is arranged between tower columns and is provided with through holes in a direction perpendicular to the axial direction of the tower columns; a bolt ball is built in The sealing cavity is provided with a threaded hole corresponding to the position of the through hole; the connecting piece includes a main rod and a plurality of struts connected with the main rod; the main rod can pass through the through hole of the sealing cavity and be connected with the bolt ball threadedly; The struts are used to connect the webs. A sealing cavity for connection is provided between the tower columns, and the bolt ball is embedded in the sealing cavity to ensure the installation stability of the bolt ball. The connecting piece is connected with the bolt ball through the through hole of the sealing cavity. It ensures the detachability of the installation of the connector, can realize the standardized prefabrication in the factory, and is easy to install on site. It avoids the residual stress and residual deformation caused by the traditional high-altitude welding on site, which affects the strength of the tower joints. At the same time, because it can be prefabricated and assembled, it has Detachable and replaceable features.

Description

technical field [0001] The invention belongs to the technical field of lattice-type wind power towers, and particularly relates to a connector for lattice-type wind power towers. Background technique [0002] Studies have shown that the wind power quality is better when the height is above 100 meters. With the development of the wind power industry, the installed capacity of a single machine continues to increase, and the tower needs a larger height above the ground. Among all kinds of wind power towers, the multi-limb column lattice concrete-filled steel tubular wind power tower can not only realize the diversification of the structure , and also has many advantages such as low cost, good reliability, good low-cycle fatigue performance, and high material utilization rate, and the engineering application prospect is very broad. [0003] The connection node of the lattice concrete-filled steel tubular wind power tower is the key component and the weakest part of the entire t...
