Sinking preventing type bridge telescoping device
The invention provides a sinking preventing type bridge telescoping device. The device comprises a first comb tooth plate and a second comb tooth plate which are distributed by mutual staggering and can be oppositely telescoped. The device is characterized in that a sinking preventing stopping part laterally extends on the sidewall close to the upper surface, of at least one comb tooth of adjacent comb teeth of the first comb tooth plate and/ or the second comb tooth plate; the sinking preventing stopping part is distributed in the length direction of the corresponding comb teeth. The device has the advantages that the sinking preventing stopping part laterally extends on the sidewall close to the upper surface, of at least one comb tooth of adjacent comb teeth of the first comb tooth plate and/ or the second comb tooth plate, and the sinking preventing stopping part is distributed in the length direction of the corresponding comb teeth, namely, the sinking preventing baffle is arranged in the length direction of the comb teeth and staggered with the comb teeth equipped with the sinking preventing baffle in the width direction of the comb teeth, and therefore, wheels of a non-motor vehicle can be effectively prevented from sinking in clearances among the comb teeth under the condition that the width of the comb teeth is unchanged, and moreover, the bearing and bending resisting performances of the comb teeth can be ensured.
