Description
Technical field
This utility model is related to power connection fitting and in particular to a kind of u shape link connects combination.
Background technology
U-shaped link of the prior art is to be formed with round steel forging, and purposes is wider, can be used alone it is also possible to two
Use in tandem, in power system using and its extensively.
In power transmission tower wind resistance Practical Project, mainly use traditional u-shaped link and begin to use in recent years
Right angle link plate.But, contacting with each other between traditional u-shaped link contacts for a point, even if contact surface is compared after abrasion deformation
For smaller, therefore in stress, stress amplitude is larger and Relatively centralized is in contact point, and the stress energy of its contact point reaches other
Tens times of position, easy wear-out failure, particularly under the fluctuating stress of high wind acts on, traditional u-shaped link bears repeatedly
The folding force of change, sweep extremely easily snaps off.Although right angle link plate changes the way of contact between u hung type ring,
Make relative complex.Although u-shaped link is simple, the destruction of u-shaped link leads to high tension electric tower to collapse or high-tension electricity
Its consequence of the fracture of line will be immeasurable.
The utility model proposes a kind of make simple, the u-shaped ring group conjunction of change version, two u hung type rings are made to connect
Contacting surface is amassed and is become big, and contact stress greatly reduces, and solves the problems, such as that power connection fitting wear-out failure is too fast.
