MECHANISM FOR FIXING THE FOLDING RAMPS OF THE TRACK SECTIONS OF THE BRIDGE BLOCK OF A MECHANIZED BRIDGE Russian patent published in 2023 - IPC E01D15/127 

FIELD: mechanized bridges.

SUBSTANCE: invention relates to mechanized bridges. The mechanism for fixing the folding ramps of the track sections of the bridge block of the mechanized bridge is made in the form of an eye on the rectangular end of one of the ramps, hinged on the track section of the bridge block, and a fork on the rectangular end of the other of the ramps. From the end of the track section in the plane of the lower chord, having a ramp with a fork, an eye is made, and from the other end of the track section, having a ramp with an eye, a fork is made in the plane of the lower chord. Lugs and forks are made with the possibility of connection by means of a locking pin manually through the shaft using a lever. To fix each ramp in the transport position, an additional mechanism is made on the outer wall of the track section.

EFFECT: reducing the time of connecting bridge blocks to each other and increasing the reliability of fixing the ramps of track sections of bridge blocks of mechanized bridges.
