Abstract

The roadbed crushing device for road and bridge construction comprises an installation frame of a U-shaped structure and a movable shell installed on the inner side of the installation frame in a sliding mode, and a connecting frame used for being connected with a mechanical arm is fixed to the side, away from the movable shell, of the installation frame; a threaded rod is fixed to the inner side of the mounting frame and is in threaded connection with a threaded sleeve rotationally connected with the movable shell, and the threaded sleeve is connected with a motor output shaft through a transmission piece mounted on the movable shell. The output shaft of the motor is further connected with a driving piece installed in the movable shell through a one-way transmission piece. And a first movable groove is further formed in the inner side of the movable shell, a movable sleeve is slidably installed on the inner side of the first movable groove, the end, facing the driving piece, of the movable sleeve is in a sealed shape and connected with the driving piece, the end, away from the driving piece, of the movable sleeve is arranged in an open shape, and an impact block is slidably installed on the inner side of the movable sleeve.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a roadbed crushing device used for road and bridge construction. Background technique [0002] The roadbed is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. When the road surface is used for a long time or is squeezed by external force, the road surface will be damaged, resulting in the road surface depression or cracking. If it is not repaired in time, the road surface will be damaged. It will affect the normal driving of the vehicle and even cause dangerous accidents. Before repairing the pavement, first crush the pavement and subgrade. If repairing on the damaged subgrade will affect the stability of the pavement, and the service life will be greatly reduced, so it is necessary to use the subgrade crushing device to crush the pavement in order to For stronger repairs to the road surface.
