The telescopic guiding device of kind, however, this guidance mode middle sleeve and the friction of guide post during the motion are mainly slided
Friction, this greatly reduces the draw of guiding, and guiding is easy to cause to be stuck.
In addition, the guiding device does column with a steel pipe 21, i.e., there are also the guiding device of a kind of idler wheel and steel pipe combination
Guiding axis, 22 4 jiaos of balancing disk respectively have the idler wheel 23 with arc groove to ride on steel pipe 21, referring to fig. 2 the right side of a and Fig. 2 b
It is shown.Or it is each form an annular space there are two the idler wheel 24 with arc groove and cover on steel pipe 25, a and Fig. 2 b referring to fig. 2
Shown in left side.Idler wheel can only roll on steel pipe face, to limit the swing and rotation of balancing disk, can only vertically transport
It is dynamic.It is gap-matched between idler wheel and column.
The advantage of this structure is column uses the cylinder of same outer diameter, the galvanized steel of suitable cross-section can be directly selected
Pipe, avoids processing, relatively inexpensive rationally and convenient for construction and installation.Moreover, such column can faster reach vertical in construction
The requirement directly spent.
However, in this configuration, steel pipe does not contact in the bosom of arc groove with idler wheel generally, but with idler wheel circular arc
There are apparent abrasion in the contact aside of the higher position of slot, idler wheel arc surface and steel tube surface contact position.

Pipe has contact, and there are certain flexible deformations for contact site, thus contact site is unlikely to be a theoretic point, and
It is a small face, as shown in the b-c-d in Fig. 3 a.Idler wheel is using rotation center O as basic point, and basic point speed is V in a flash for certain,
Direction is upward, and the angular speed of idler wheel is ω, rotates clockwise, then the instantaneous linear velocity of instantaneous center of velocity a point is Va=ω × R, connects
Other each point radiuss of turn and a point are inconsistent in contacting surface, therefore there is opposite sliding between these points and static steel pipe, are formed and are slided
Dynamic friction leads to the contact surface abrasion of idler wheel and steel pipe.
Therefore, the movement of idler wheel and steel pipe is not the rolling in ideal, and is often slided.Force of sliding friction relatively rolls
Frictional force is much bigger.This is just determined when the gradient in balancing disk motion process is still within allowed band, is contacted
The force of sliding friction in face, which also will increase, makes frictional force be greater than the tractive force that gas rises in air bag, when serious between idler wheel and steel pipe
Stop motion causes guiding to be stuck, and device breaks down.Therefore, this guiding mechanism is only applicable to the lesser dress of gas-storing capacity
