The invention discloses a sectional cutting device for a concrete brace of an overhead line system. The sectional cutting device comprises a carrier, a clamping device and a cutting component, whereinthe front surface of the carrier is provided with a vertical clamping groove with a U-shaped cross section; the clamping device comprises a first clamping device and a second clamping device; the first clamping device comprises fixed clamping plates, active clamping hydraulic cylinders and active clamping plates, wherein the fixed clamping plates are arranged on two sides of a carrier clamping groove, and the active clamping plates are fixedly connected with the driving clamping hydraulic cylinders; the second clamping device comprises a long clamping hydraulic cylinder, a long clamping plate, a short clamping hydraulic cylinder and a short clamping plate, wherein the long clamping hydraulic cylinder is hinged to the upper surface of the short clamping hydraulic cylinder and is hinged tothe long clamping plate, the short clamping hydraulic cylinder is hinged to the short clamping plate; and the cutting component comprises a saw blade, a driving motor, a sliding plate, a linear guiderail and a lead screw, wherein the saw blade and the lead screw are driven by the motor. According to the sectional cutting device, on-site sectional cutting of the concrete brace of the overhead linesystem can be realized, the transportation cost of waste brace treatment is effectively reduced, and the processing process of the waste brace is accelerated.
Description
technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a segmental cutting device for catenary concrete pillars. Background technique [0002] Concrete pillars of railway catenary are the supporting equipment of electrified railway catenary. Most of the prestressed concrete pillars are square pillars with I-shaped ventral structure, which are generally made of steel bars and concrete. In the replacement process of electrified railway equipment, a large number of old catenary concrete pillars need to be removed. The existing removal method is to manually break them from the bottom, lift the whole section of waste pillars by lifting equipment, and place them on large transport vehicles During the process, it is transported to relevant processing units for subsequent recycling. Due to the long length of the entire waste pillar, without pretreatment, it will bring great inconvenience to its subsequent transportation, crushing ...
