Two-direction pre-tensioned prestressing ballastless track slab movable tensioning equipment

Abstract

Two-direction pre-tensioned prestressing ballastless track slab movable tensioning equipment comprises a side pre-locking beam, a side tensioning beam, an end pre-locking beam and an end tensioning beam; the side pre-locking beam and the side tensioning beam are assembled on two walking beams through a pair of side beam linear guide rails, and each walking beam is provided with wheels matched with a running rail, walking guide wheel sets, a wheel speed reduction motor and side beam advancing and retreating oil cylinders; portal frames are arranged at the two ends of the walking beams, and a lifting frame, a lifting frame lifting oil cylinder and a lifting frame lifting guide device are assembled on each portal frame; and the end pre-locking beam and the end tensioning beam are assembled on the lower faces of the lifting frames through a pair of end beam linear guide rails, and end beam advancing and retreating oil cylinders are arranged on the lifting frames. According to the equipment, the production preparation period can be effectively shortened, the engineering construction cost is reduced, industrial pollutions are avoided, and meanwhile a steel mold fixed mounting production manner facilitates simplifying of a mold structure, reduction of cost, improvement of precision and reduction of occupied areas and working energy consumption of production equipment.

Description

technical field [0001] The invention relates to high-speed railway ballastless track slab production equipment, in particular to a bidirectional pretensioned prestressed ballastless track slab mobile tensioning equipment. Background technique [0002] At present, the two-way prestressed prestressed ballastless track slab production of CRTSⅢ type mostly adopts the foundation pit operation method, which requires the construction of foundation pit facilities and pre-embedded tensioning devices. Not only the production preparation period is long, the project cost is high, and Because the pre-buried tensioning equipment cannot be relocated and reused, it will also cause industrial pollution. The prior art discloses a track slab production line with mold movement, and its prestressed tensioning equipment is still not completely separated from the prestressed tensioning mode of the original foundation pit operation mode, and the entire production equipment is connected into a produ...
