BRIDGE LAYER MACHINE UNIFIED LINING-SCREEN Russian patent published in 2018 - IPC E01D15/127 

FIELD: construction; machine building.

SUBSTANCE: bridge-laying machine unified lining-screen after the bridge block (2) laying on the obstacle by the bridge-laying machine (1) consists of covering elements (12) removed from the bearing brackets by means of the eccentrics (5) locks opening. Detachable joints release the rods, the latter are fully pulled out of the bearing casings due to the rotation (with shift in the boring holes) in the L-shaped brackets (10) hinges (9). Unfastened set of parts, including rods, L-shaped brackets (10), external (front) pairs of covering elements (12), rotate on bends (11) relative to the rectangular holes, placed in the posts (4) lower parts before the L-shaped brackets (10) ending with rods laying on the ground. Undocked coverings element (12) is laid ashore with insufficient soil bearing capacity and articulated with the bearing pipe (16) docking nodes (13) by grooves, which is fixed in the bridge unit (2) ends vertical grooves with its lugs (14).

EFFECT: bridge laying machine unified lining-screen is designed to increase the arranged by the tracked bridge laying machine bridge transition throughput, and increase its protection level against fire damage means during operation.
