Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the present invention can be mutually combined.
The embodiment of middle pipe busbar supporting device of the present invention：As shown in Figure 1 to Figure 3, the support meanss are that one kind is applied to
Pipe bus support system in high tension transmission, by some some support units for being segmented support successively along pipe bus length direction
100 compositions, each support unit 100 are divided into support section 101 and the two parts of hydraulic control part 102 again.
Support section 101 is mainly made up of base 1, bracket 2 and the three parts of relocation mechanism 3.The main body of base 1 uses ABS
The ring flange of plastic material, its top are convexly equipped with the convex tendon 11 of front and rear extension, and convex tendon 11 has two and is parallel to each other isometric, and two is convex
The sliding groove of front and rear extension is offered on muscle 11, the rear and front end of sliding groove is provided with buffering segmental arc, buffers the song of segmental arc
Rate is more than the curvature of sliding groove middle part.Bracket 2 uses ABS plastic material, and its bottom uses trapezium structure, diverged in two convex tendons
11 opposite both sides, and the support shaft 21 run in the guide in sliding groove is fixed with the bottom of trapezium structure, support shaft 21 is circle
Cylindricality, so that bracket 2 can be with respect to reciprocatingly sliding before and after base 1；The top of bracket 2 is provided with the inner sleeve 22 and overcoat of mutual sheathing
23, overcoat 23 is integrally disposed upon on bracket 2, and inner sleeve 22 is located in overcoat 23.Relocation mechanism 3 is mainly by several along the circumferential direction equal
Hydraulic leg 31 of the cloth between inner sleeve 22 and overcoat 23 forms.The one end of hydraulic leg 31 is the fixing end for being fixed on inner sleeve 22,
The other end is assemblied in the movable end of overcoat 23 to roll, and movable end can be relative to fixing end along the radial expansion of inner sleeve 22.Hydraulic pressure branch
Leg 31 is actively extension and the single-acting cylinder structure passively retracted.Spiral guide rail is provided with the inwall of overcoat 23,
There is rolling to be arranged on the roller in guide rail around certain axis connection on the movable end of hydraulic leg 31.
Hydraulic control part 102 is mainly made up of two-way pump 41, reversing motor 42 and hydraulic control pilot valve 43.On the hydraulic fluid port of hydraulic cylinder
And the control mouth of the oil inlet of two-way pump 41, the oil return opening of reversing motor 42 and hydraulic control pilot valve 43 is connected to, hydraulic control pilot valve 43
Oil inlet be connected with the oil inlet of the reversing motor 42 of residing hydraulic leg, the oil-out of hydraulic control pilot valve 43 and adjacent hydraulic pressure
The press oil port of the two-way pump 41 of supporting leg is connected.Preferably, two-way pump 41 and reversing motor 42 use blade shape, and blade is adopted
The edge of quality of rubber materials is installed additional with quality of rubber materials or edge, to improve the flexible pressurized effect of hydraulic energy.
When in use, as pipe bus starts to reverse, on the support unit 100 of original position, two-way pump startup, control
The execution unit action of hydraulic control pilot valve, the oil inlet of hydraulic control pilot valve control reversing motor are opened；Meanwhile with original position phase
On adjacent support unit 100, two-way pump also starts, and hydraulic oil is injected into the reversing motor of original position support unit 100, and
And hydraulic oil is also sent into the reversing motor of original position by the reversing motor of adjacent position through two-way pump；By that analogy, reverse
Position is longer, and the hydraulic oil that the reversing motor of original position obtains is more, and pressure is bigger, and rigidity is also bigger, it is achieved thereby that from
Move the function of anti-torsion.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
