A tower joint connection structure for a composite material tower

Abstract

The invention discloses a tower section connection structure for a composite material tower. The connection structure comprises a tower base, anti-shaking supporting arms, a connection sleeve, threaded pushing rods, and squeezing plates, wherein the connection sleeve is arranged at the top end of the tower base; a tower rod is arranged at the top end of the interior of the connection sleeve; threeguiding rotation chambers are formed in the outer side wall of the end of the tower rod located inside the connection sleeve, three guiding rotation chambers are formed in the outer side wall of theend of the tower base located inside the connection sleeve, and the included angle between every two adjacent guiding rotation chambers is 120 DEG; a dovetail sunk groove is formed in the surface of the tower base on one side of each corresponding guiding rotation chamber, and a dovetail sunk groove is formed in the surface of the tower rod on one side of each corresponding guiding rotation chamber; arc-shaped sliding frames are arranged on the inner side walls of the connection sleeve in positions corresponding to arc-shaped anti-slip stripes; the squeezing plates are mounted at the ends, faraway from the inner side walls of the connection sleeve, of fastening springs; arc-shaped supporting plates are arranged on the inner sides of adjusting chambers; dovetail anti-drop strips are fixedat the two ends of the side of each arc-shaped supporting plate far from the corresponding adjusting chamber. The connection structure provided by the invention has the advantages that high safety andhigh convenience in use are achieved, and the connection structure achieves an anti-shaking function when being used for connection of the tower.

Description

technical field [0001] The invention relates to the technical field of composite material towers, in particular to a tower joint connection structure for composite material towers. Background technique [0002] According to structural materials, pole towers can be divided into wood structure, steel structure, aluminum alloy composite structure and reinforced concrete structure pole tower. Wooden structure pole towers have been eliminated in China due to low strength, short life, inconvenient maintenance, and limited timber resources. , Steel structures can be divided into trusses and steel pipes. Lattice-shaped truss towers are the most widely used and are the main structure of lines above ultra-high voltage. Aluminum alloy structure towers are only used in mountainous areas where transportation is particularly difficult due to their high cost. Reinforced concrete poles are all used Centrifuge pouring, steam curing, it has a short production cycle, long service life, simple ...

[0002] According to structural materials, pole towers can be divided into wood structure, steel structure, aluminum alloy composite structure and reinforced concrete structure pole tower. Wooden structure pole towers have been eliminated in China due to low strength, short life, inconvenient maintenance, and limited timber resources. , Steel structures can be divided into trusses and steel pipes. Lattice-shaped truss towers are the most widely used and are the main structure of lines above ultra-high voltage. Aluminum alloy structure towers are only used in mountainous areas where transportation is particularly difficult due to their high cost. Reinforced concrete poles are all used Centrifuge pouring, steam curing, it has a short production cycle, long service life, simple maintenance, and can save a lot of steel. The concrete poles using partial prestressing technology can also prevent cracks in the poles. The quality is reliable. China uses the most, accounting for It ranks first in the world. However, the connection structure of the tower section is often used in the use of composite material towers. At present, the connection effect of the general connection structure is often poor during use, and it is easy to detach and shake the connecting parts. Thus greatly affecting the safety of the tower joint connection structure in use
