Material-saving and be easy to monitor.
In technique scheme, described spacing base plate is located between described base-plate and described guide seats.Realize
Rotary shaft drives guide seats to follow support pipe portion and rotates freely.
In technique scheme, described rotary shaft upper end is welded in described guide seats lower end, and under described rotary shaft
End is located in described rotary shaft stopper slot.Realize rotary shaft and follow support pipe portion rotating freely, and drive guide seats to follow
Frame pipe portion rotates freely.
In technique scheme, the rotation angle θ of described rotary shaft and described guide seats is -90 DEG C～90 DEG C.Maximum
Meet to limit the thermal expansion demand of piping.
This utility model has the advantage that：
(1) increase a rotary shaft in the bottom of guide seats, do not limit base and rotate but restricted guidance bottom with pipe portion
The displacement of the lines of seat；
(2) rotary shaft is placed in bottom rotating shaft stopper slot, and guide seats can freely follow the rotation of support pipe portion, thorough
Bottom eliminates and friction self-locking phenomenon occurs；
(3) eliminate safe hidden trouble：Solve the problems, such as the friction self-locking when angular displacement is larger for the guide type shoe, thus decreasing
Because friction self-locking leads to the reversed risk of support；
(4) rotation angle θ of rotary shaft and guide seats is -90 DEG C～90 DEG C, and the heat meeting piping to greatest extent is swollen
Swollen demand.
