The invention particularly relates to a prefabricated ballastless track board air turning device, which is used for solving the problems of the traditional method for turning the existing track board by adopting a crane matched with sole timber such as existence of safety potential hazard, time and labor waste and likeliness for damaging the track board. A lifting chain is arranged between a suspension ring and the left side of a lifting beam and another lifting chain is arranged between the suspension ring and the right side of the lifting beam, the lower end surface of the lifting beam is provided with pulley support seats and an electric block, and a fixed pulley is arranged on each pulley support seat; a turning mechanism comprises hanging brackets, a connecting beam is arranged between the end parts of the two hanging brackets, the middle part and the front bottom of each hanging bracket are respectively provided with a connecting lifting lug, the front top of each hanging bracket is provided with a riding wheel, the middle part of the connecting beam on the rear end of hanging bracket is provided with an electric block lifting lug, a wire rope is connected to the two connecting lifting lugs, the left side and the right side of each hanging bracket are provided with a rotary carrier hook in a penetrating manner, each rotary carrier hook is provided with a positioning pin, and a hydraulic jack is arranged in each hanging bracket. By adopting the prefabricated ballastless track board air turning device, the track board can be turned randomly in the air in the lifting process, and the prefabricated ballastless track board air turning device is flexible, safe and reliable to operate.
Description
technical field [0001] The invention relates to an overturning device for a ballastless track slab of a high-speed railway, in particular to an aerial overturning device for a prefabricated ballastless track slab capable of realizing horizontal and vertical inversion during hoisting. Background technique [0002] CRTSⅢ slab ballastless track technology is a ballastless track system with independent intellectual property rights in my country, and the track slab is an important part of the system. The track slabs are generally produced in a centralized manner in a factory, and are transported to the construction site for laying and construction to form a ballastless track bed. [0003] The production of track slabs is horizontal prefabrication. After the mold is released, in order to prevent warping and deformation of the track slabs, the track slabs must not be stored in multiple layers or stacked horizontally for a long time. To meet the needs of the construction period, it...
