The invention provides a tension stand for ballastless high-speed railway track board production. The tension stand comprises a stand beam assembly, a supporting beam assembly and a mechanical tension assembly, the stand beam assembly comprises a first tension beam, a first fixed beam, a second fixed beam and a second tension beam which are sequentially connected into a closed square in a threaded manner, one end of the mechanical tension assembly is fixedly connected with the outer side of the first tension beam or the second tension beam, the mechanical tension assembly comprises a driving motor and a ball screw, an output shaft of the driving motor is connected with a driving sprocket, the driving sprocket is connected with a driven sprocket through a chain and sleeves the ball screw, and a small ball bearing, a pressure bearing plate, a pressure bearing, a large ball bearing, a supporting sleeve and a dustproof sleeve sequentially sleeve the ball screw on the other side of the driven sprocket. The tension stand for ballastless high-speed railway track board production is low in early construction difficulty, convenient and rapid to mount, simple in later detachment and reusable.
Description
technical field [0001] The invention belongs to the field of CRTS III type ballastless high-speed railway track slab production equipment, and in particular relates to a tensioning stand used for ballastless high-speed railway track slab production. Background technique [0002] With the development of high-speed railway technology, all kinds of new ballastless tracks are replaced by concrete or asphalt mixture, etc., aiming at improving the stability and smoothness of the track and greatly reducing the maintenance workload. Ballastless track has been laid and applied in large quantities on new high-speed railway lines, and has achieved good technical and economic results. [0003] In order to meet the needs of the "going out" strategy of China's railways, it is necessary to enhance the independent innovation of China's ballastless track technology and build its own brand of China's ballastless track. For this reason, on the basis of summarizing the research and application...
