Cambered surface slowly declines, and the lower extreme point of the second arc surface is consistently higher than the lower extreme point of the first arc surface, therefore does not have corner angle punching
Striking wheel tire protects tire well, meanwhile, it is convex it is stupefied increase frictional force, prevent from skidding, when generating flexible between beam body, stretch
Contracting plate can move in guide groove, and beam body is avoided to generate internal stress.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A schematic enlarged-scale view of Fig. 1.
In figure: 1 beam body, 2 pedestals, 3 supporting plates, 4 expansion plates, 41 second arc surfaces, 42 guide plates, 43 guide cylinders, 44 springs,
It is 45 limit plates, 46 pull rods, 47 convex stupefied.
Specific embodiment
As shown in Fig. 1 to 2, a kind of buffer-type bridge extension joint, including beam body 1, beam body 1 are set as left and right two, two
There is expansion joint between beam body 1, and the opposite side in upper end of two beam bodies 1 offers rectangular holding tank, leads in holding tank
The pedestal 2 that anchor bolt is fixed with L-type is crossed, the pedestal 2 in left side is L-shaped, and the pedestal 2 on right side is symmetrical arranged, the upper surface of pedestal 2 and beam
For the upper surface of body 1 in same level, the opening of two pedestals 2 is opposite, and the inner cavity bottom end of pedestal 2 is equipped with water by guiding device
Flat supporting plate 3, the upper surface of supporting plate 3 and beam body 1 are in same level face, and the right end of the supporting plate 3 in left side offers guide groove, guide groove
Inside it is plugged with the expansion plate 4 of the fixation of supporting plate 3 on right end and right side, the right side of the supporting plate 3 in left side and the connection circular arc of upper surface
Transition, and the connection arc transition of the upper surface of the supporting plate 3 of the upper surface of expansion plate 4 and right side, have prevented corner angle worn tire,
Reduce vibration.
The connection of two pedestals 2 opposite inner cavity surface and upper end is inclined first arc surface, in this way there will be no corner angle,
The connection of two supporting plates 3 opposite one end and upper end is inclined second arc surface 41, and there will be no corner angle in this way, is convenient for tire
It rolls, and there are buffer distance, guiding dresses between the lower extreme point of the first arc surface of the lower extreme point and downside of the second arc surface 41
Multiple downward guide plates 42 including being fixed on 3 lower end of supporting plate are set, and the lower end of guide plate 42 is socketed with lower end and is fixed on bottom
The guide cylinder 43 of 2 inner cavity bottom ends of seat, is connected between the lower end of guide plate 42 and the inner cavity bottom end of guide cylinder 43 by spring 44, and
The lower end of guide plate 42 is fixed with the downward limit plate 45 in spring 44, the lower end to 43 inner cavity of guide cylinder of limit plate 45
The distance of bottom end is consistent with buffer distance, that is, when the arrival bottom end of limit plate 45, buffering terminates.
First disc will not thus have the gap together with the lower extreme point of the second arc surface, will not worn tire, first
It is uniformly provided with convex stupefied the 47 of the bar shaped that front and back is arranged on arc surface and the second arc surface 41, increases frictional force, prevents from skidding, two
The opposite one end of pedestal 2 is respectively and fixedly provided with reinforcing mechanisms, and reinforcing mechanisms include the drawing that the free end being fixed on pedestal 2 tilts down
Bar 46, and the free end of pull rod 46 is fixed with pulling block, prevents pedestal 2 to be detached from the opposite end face of two holding tanks, avoids the two
Between generate gap, booster action.
When vehicle drives into, the first arc surface can be contacted first, thus can slowly be declined, the second circular arc is then touched
Face 41, because of the second arc surface 41, two supporting plates 3 do not have corner angle on the upside of opposite end face, thus will not worn tire, simultaneously
Second arc surface makes tire slowly compress supporting plate 3, under the action of spring 44, plays the role of bumper and absorbing shock, reduces impact, protects
River bottom protection seat 2 increases service life, and when vehicle is driven out to the supporting plate 3 of the other side, the second arc surface 41 of the other side is first contacted,
Slowly decline, and the lower extreme point of the second arc surface 41 is consistently higher than the lower extreme point of the first arc surface, therefore does not have corner angle impact
Tire protects tire well, meanwhile, convex stupefied 47 increase frictional force, prevent from skidding, and when generating flexible between beam body 1, stretch
Contracting plate 4 can move in guide groove, and beam body 1 is avoided to generate internal stress.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
