The additional technical characteristics are as follows: the top surface of the first toothed plate and the top surface of the second toothed plate are respectively provided with an anti-slip groove;
the anti-skid groove is in a sawtooth shape.
The utility model provides a strengthen crashproof bridge telescoping device, be provided with first anchor board below the first pinion rack, first anchor board even as an organic whole with first pinion rack welding, be provided with second anchor board below the second pinion rack, second anchor board even as an organic whole with second pinion rack welding, during the installation, with first anchor board, second anchor board welds with pre-buried anchor muscle mutually, first pinion rack and second pinion rack are through first anchor board, second anchor board welds as a whole with the anchor muscle, the not hard up scheduling problem that drops of original pre-buried bolt has been avoided, it is firm to connect. And the top of second anchor board includes anterior recess, middle part platform, rear portion slope, and second pinion rack rear end sets up on anterior recess and contacts with the middle part platform, and the height phase-match of middle part platform and the height of second pinion rack, rear portion slope front end and middle part platform smooth transition for the second pinion rack is in the protection of second anchor board. The second toothed plate sets up the direction that comes at the highway, and when the snow removing shovel snow removing, the snow removing shovel pushes down on the road surface, when reacing the telescoping device, just reaches the second toothed plate through rear portion slope, middle part platform, and rear portion slope, middle part platform offset snow removing shovel flat push most component, can directly not strike the second toothed plate that sets up in the direction that comes, and the telescoping device receives the protection, extension live time. And the top surface of first pinion rack, the top surface of second pinion rack are provided with anti-skidding groove respectively, and anti-skidding groove is the sawtooth pattern. When a vehicle passes through, the anti-slip grooves increase the friction between the tire and the top surfaces of the first toothed plate and the second toothed plate.
