The invention discloses a segmental cutting device for catenary concrete pillars, which includes a carrier, a clamping device and a cutting assembly; the front of the carrier is provided with a vertical clamping groove with a U-shaped cross section; the clamping device includes a first clamping device and the second clamping device; the first clamping device includes fixed splints and active clamping hydraulic cylinders installed on both sides of the carrier clamping groove, and the active clamping plate is fixedly connected with the active clamping hydraulic cylinder; the second clamping device includes a hinge The long clamping hydraulic cylinder and the long splint hinged with it, the short clamping hydraulic cylinder and the short splint hinged with it on the upper surface of the carrier; the cutting components include saw blades, driving motors, sliding plates, linear guides and lead screws, The blades and lead screws are driven by motors. The invention can realize segmental cutting of waste catenary concrete pillars on site, effectively reduces the transportation cost of waste and old pillars, and is beneficial to speed up the treatment process of waste and old pillars.
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 ...
