Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] figure 1 As shown, the pretensioning method of the present invention produces a steel bar tensioning device for ballastless track slabs of high-speed railways, including a tensioning and positioning locking mechanism, wherein the tensioning mechanism consists of at least two tensioning cylinders 7 to form a tensioning cylinder group or The tensioning power mechanism is in one-to-one correspondence with the reinforcing bars / tensioning rods on the corresponding side of the track slab mould. The above-mentioned tensioning oil cylinder is installed on the tensioning platform through the horizontally arranged guide columns fixed on the tensioning platform and the guide plates matched with the guiding columns. In this embodiment, two tensioning cylinders 7 are longitudinally arranged and installed between the fixed plate 4 and the rear guide plate 5. A tensioning p...

A reinforcing steel bar tensioning device of a high-speed railway ballastless track plate with a pre-tensioning method comprises a tensioning power mechanism fixed to a tensioning bed box through a guide post and a guide rod. The tensioning power mechanism is composed of two tensioning oil cylinders fixed side by side as a whole and is provided with a tensioning rod link head connected with a tensioning rod. The tensioning rod link head is connected with the end of a tensioning oil cylinder rod. The upper hole of the tensioning rod link head is a tensioning rod hole. According to the reinforcing steel bar tensioning device of the high-speed railway ballastless track plate with the pre-tensioning method, the tensioning device is fixed on the tensioning bed box through the guide post and the guide rod, installation, overhaul and replacement are convenient, the two tensioning oil cylinders corresponds to one tensioning rod and operates synchronously, the device volume is reduced and the tensioning power is ensured. a location locking mechanism is arranged to cooperate with the tensioning oil cylinders, precisely locating and locking in time during the tensioning process are realized, the synchronous tensioning and locking of all reinforcing steel bars are ensured, the situation of difference stress does not happen. The plug plate mechanism enables all tensioning mechanisms to be locked synchronously. In addition, plug plates are cooperated with each other in a contacting mode, the synchronous placing of the plug plates is ensured, the independent work between the tension mechanism and the corresponding tensioning rod is ensured, and the tensioning accuracy control is more accurate.
Description
technical field [0001] The invention relates to a special steel bar tensioning device for a ballastless track slab production line laid on a high-speed railway, in particular to a high-speed railway track slab pretensioning steel bar tensioning device. Background technique [0002] The pre-tensioning process of the prior art produces high-speed railway ballastless track slabs. There are two main methods for the tensioning steel bar process. One is the overall tensioning process. The tensioning steel bars that enter the mold are connected to the tension rods, and all the tension rods are fixedly connected. To a tension beam, the hydraulic device applies tension to the tension beam to complete the prestress setting of the steel bar. The disadvantages of this method are that the stress of each steel bar is unbalanced, the quality of the track slab is difficult to guarantee, the amount of manual work is large, and the production cost is high. The second is a single steel bar te...
