Wheel is installed using pattern arranged side by side, can reach the effect of self-regulation, i.e., fiberglass inner arm stretches out longer, can be produced certain curved
Song, now idler wheel mechanism can be automatically adjusted according to the bending situation of fiberglass, allow fiberglass inner arm fully to be contacted with idler wheel mechanism,
Ensure the effect slided.Rolling bearing is rotated, and resistance is small, and regulation bearing uses Nonlubricated bearing, rotating effect
It is good, fully solve the service life of all defect of nylon, protection hydraulic system and Parts Made of Composite Glass, its technical scheme used
It is as follows：
One kind mixing arm type insulating overhead operating vehicle telescopic arm idler wheel mechanism includes：Institutional framework；Wheels side installing plate；Rolling
Dynamic bearing；Driven shaft；Adjustment axis；Oilless bearing；Roller, rolling bearing is installed in roller, and each roller two ends are respectively installed
Two rolling bearings, two sets of roller devices after installation constitute pattern arranged side by side by wheels side installing plate and driven shaft, used with axle
Back-up ring is fixed to the two ends of driven shaft, prevents driven shaft axial float, thus by wheels side installing plate, rolling bearing, driven
Axle, roller form a whole roller a, in the axis hole that oilless bearing is respectively installed to overall roller a and institutional framework, pass through
Overall roller a is installed on institutional framework by adjustment axis.
On the basis of above-mentioned technical proposal, the institutional framework is to be welded in advance on outer arm, in outer arm socket and inner arm.
On the basis of above-mentioned technical proposal, the two ends of the adjustment axis are pushed down with plain cushion and bolt, prevent adjustment axis axial direction
Play.
The beneficial effect that the utility model is produced has：Arm type insulating overhead operating vehicle telescopic arm idler wheel mechanism is mixed, is used
Roller pattern, i.e., be provided with the idler wheel mechanism of pattern arranged side by side, fiberglass inner arm is in contact with roller, in roller on the downside of outer arm
Portion is provided with rolling bearing, by the rotation of roller, reaches the purpose of fiberglass inner arm stretch/shrink, and two rollers are using simultaneously
Row pattern is installed, and can be reached that the effect of self-regulation, i.e. fiberglass inner arm stretch out longer, can be produced certain bending, now roll
Wheel mechanism can be automatically adjusted according to the bending situation of fiberglass, allow fiberglass inner arm fully to be contacted with idler wheel mechanism, it is ensured that be slided
Effect.Rolling bearing is rotated, and resistance is small, and regulation bearing uses Nonlubricated bearing, and rotating effect is good, fully solution
Determine the service life of all defect of nylon, protection hydraulic system and Parts Made of Composite Glass.

Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
As shown in Figure 1-Figure 3, a kind of pipe fitting laying rack includes：1st, institutional framework；2nd, wheels side installing plate；3rd, the axis of rolling
Hold；4th, driven shaft；5th, adjustment axis；6th, oilless bearing；7th, roller, rolling bearing 3 is installed in roller 7, each roller two ends
Two rolling bearings are respectively installed, two sets of roller devices after installation constitute parallel type by wheels side installing plate 2 and driven shaft 4
Formula, the two ends of driven shaft 4 are fixed to shaft block ring, the axial float of driven shaft 4 is prevented, thus by wheels side installing plate 2, rolling
Dynamic bearing 3, driven shaft 4, roller 7 are formed a whole roller a, and oilless bearing 6 is respectively installed into overall roller a and mechanism frame
In the axis hole of frame 1, overall roller a is installed on institutional framework 1 by adjustment axis 5, institutional framework 1 is to be welded on outer arm in advance
On.When inner arm is protruding, the lower surface of inner arm is directly born against on roller, and inner arm lower surface can produce friction with roller 7, from
And drive the rolling bearing 3 in roller 7 to rotate, inner arm lower surface is so avoided with roller 7 and produces sliding friction, and is rolled
Dynamic bearing 3 rotate flexibly, it is necessary to adhesive force it is very small, so as to reduce the pressure of hydraulic system, improve the use of hydraulic oil
Life-span and Hydraulic Elements and the service life of sealing, when inner arm stretches out longer, inner arm can produce certain flexural deformation, now whole
