Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this
The embodiment of invention, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to protection scope of the present invention.
The pantograph bow suspension of the present invention, its preferable embodiment are：
In the upper arm assembling of pantograph, including spring case structure, the spring case structure include upper shell with
Pedestal, the upper shell is interior to be provided with spring assembly and the axis of guide, and the top of the lower base is inserted into the upper shell, described
The upper end of lower base is against on the spring assembly, and the axis of guide is inserted into the core bore in the middle part of the lower base, under described
Pedestal is connected with the lower end of two groups of supporting splints, and the upper end of two groups of supporting splints is connected by slide plate mounting seat and carbon slipper
Connect, the upper shell is connected respectively with connector and bow angle.
Linear bearing is provided between core bore in the middle part of the axis of guide and the lower base.
The spring case it is in-house be provided with it is spacing, the vertical displacement of the lower base is within 60mm, under described
Pedestal is on ring without constraint.
The spring assembly is variable rate spring.
The pantograph bow suspension of the present invention, for the suspension connection between carbon slipper and pantograph, there is knot
Structure is compact, small volume, it is in light weight, be easily installed, the features such as windage is small, non-maintaining.
Specific embodiment：
As shown in Figure 1, Figure 2, Figure 3 shows, mainly by spring case structure 1, supporting splint 2, connector 3, slide plate mounting seat 4, carbon
Slide plate 5 and the bow grade of angle 6 composition.
After carbon slipper 5 is connected by the supporting splint 2 of slide plate mounting seat 4 with spring case structure 1, carbon slipper 5 and lower base 10
Form a rigid connection body.Due to the change of the Interaction Force of carbon slipper 5 and contact net or there is the impact from contact net
When, carbon slipper 5 moves in vertical direction together with lower base 10, linear bearing 16, blanking cover 15 etc. along guide rod 12, due to bullet
Spring component 14 connects together upper shell 9 and two big part flexibility of the grade of lower base 10, so having buffering in vertical direction and absorbing
The function of impact；Spacer pin 6 plays position-limiting action simultaneously, and guarantee spring case is 60mm in vertical range.
Bow suspension is used for pantograph, and spring case structure 1 uses bolt by the upper shell 9 on top with connector 3
Connection, spring case structure 1 are connected by screw bolts by the lower base 10 of bottom with two groups of supporting splints 2, slide plate mounting seat 4 and two
Group supporting splint 2 is bolted, while supporting splint 2 is formed to the structure of closed stablity, and carbon slipper 5 is pacified installed in slide plate
Fill the top of seat 4.
The upper shell 9 on the top of spring case structure 1 is fixing end, and the lower base 10 of bottom is movable end, and movable end bottom is sealed
Close.The top of spring assembly 14 is connected by bolt with upper shell 9, the axis of guide 12, and the bottom of spring assembly 14 passes through spacer pin
13 are directed to axle 12 (axis of guide in the middle part of be provided with oblong slots) and lower base 10 is connected.There is linear bearing 16 inside lower base 10
(2 groups), sealing ring 17 (2 groups), each serve as guiding and sealing function；There is pump nozzle 18 in the outside of lower base 10, is easy to daily
Lubricated maintenance management.
When pantograph from contact net by being impacted, carbon slipper 5 drives supporting splint 2 and lower base 10 along guiding
Axle 12 moves downward, and the tension of spring assembly 14 is elongated, buffers and absorb the impact shock from contact net.When impact disappears
Afterwards, in the presence of spring assembly 14, carbon slipper 5 drives supporting splint 2 and lower base 10 to be moved upwards along the axis of guide 12, real
The dynamic following of pantograph is showed.
Wherein, spring assembly 14 uses variation rigidity coefficient spring, i.e. spring stiffness values with the directly proportional change of spring elongation amount,
Final realize buffers and absorbs the impact shock between bow net to a greater extent in limited stroke range.
Such as Fig. 3, the gross three-dimensional structure schematic diagram of bow suspension.
In summary described, of the invention pantograph bow suspension, existing process disclosure satisfy that manufacture demand, group
It is simple to fill technique, conveniently manually adjusts, the good contact of pantograph collector head part and contact net can be realized in operation, mitigates slide plate
Inordinate wear, so as to preferably ensure pantograph stabilization flowed.
