BRIDGE LAYER Russian patent published in 2016 - IPC E01D15/22 

FIELD: construction.

SUBSTANCE: invention relates to bridge-layers and can be used for guidance of mechanized bridges over obstacles or as a ramp. To lay a bridge over obstacle 22 at first sections 16, 18 are lifted upwards, for this purpose, engines which rotate worms 5, 14 are used. As a result gear 3 starts rotating on the bushing 4 and section 16 of the bridge starts turning too. Gear 11 with axis 9 and drive sprocket 10 will turn simultaneously by means of worm wheel 13 and globoidal worm 12 connected with it. Driven sprocket 19 will turn on axle 13 together with section 18 of the bridge by means of chain 20 turns. After the sections reach the vertical position, they are lowered using the first motor, while the second motor is turned off, then, the first motor is switched off when the section (sections) come in contact with the ground.

EFFECT: invention aims at simplifying the design, reducing the power consumption and improving operational characteristics.
