Technical field
It the utility model is related to a kind of increasing footpath panel assembly.
Background technology
In recent years, as the generally raising of product quality, the specification of pickling machine set outlet finished product internal diameter 762 can not meet user
To the demand of volume 610；Consider universal 762 specification of raw material and a small amount of 610 and return the demand of acid, it is necessary to consider to become in entrance uncoiler
Footpath, while increase footpath plate and need to be used as a kind of normality, high-strength steel especially well sold and in short supply to market, acid-washing stainless steel are (with product matter
The increasingly lifting of amount, some unit coiling tension requirements reach 200kN), the increasing footpath plate used normality is even more a kind of test.It is logical
Often increase footpath plate to be directly attached using bolt with fanning strip, this connected mode axial direction suffered by bolt in the course of the work
Shearing force easily makes bolt fracture, therefore, in general increase footpath panel assembly be difficult meet high-strength steel, the normality of stainless steel uses need
Ask.
The content of the invention
The purpose of this utility model is that providing one kind increases footpath panel assembly, and the utility model can avoid increasing footpath plate and fanning strip
Connecting portion fracture.
The technical scheme for solving above-mentioned technical problem is as follows：
