High-speed railway track plate pre-tensioning method flow assembling unit production line tensioning device

Abstract

Provided is a high-speed railway track plate pre-tensioning method flow assembling unit production line tensioning device. A ground support seat with the fixed height supports a tensioning bed box through a universal bead. A tensioning power mechanism is fixed to the tensioning bed box. A track plate production line transferring track is arranged on the inner side of the ground surface of the ground support seat. Track plate locating support seats are arranged on the two sides of the transshipment track. According to the high-speed railway track plate pre-tensioning method flow assembling unit production line tensioning device, the height of the tensioning bed box is fixed, the height of a mold is corresponding to the height of the tensioning bed box at the time of operation and the operation height does not need to be adjusted. The high-speed railway track plate pre-tensioning method flow assembling unit production line tensioning device is simple, capable of saving time and effort. A traverse movement oil cylinder and a feed oil cylinder are arranged, the locating and taking place of the tensioning bed box are more flexible and accurate. The tensioning power mechanism adopts double oil cylinders or multiple oil cylinder combinations, the device size can be reduced, the tension power is more ample, and the tension process is simple and smooth.

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 tensioning device for a high-speed railway track slab pretensioning assembly line production line. Background technique [0002] The pre-tensioning method in the prior art mainly adopts the fixed pedestal method to produce ballastless track slabs for high-speed railways. The tensioning process of this method is that eight pedestals share a tensioning movable beam to simultaneously drive multiple steel bars to tension. The shortcomings of the process are low tensioning precision, many manual intervention links, low utilization rate of molds, low production efficiency, large equipment footprint, high difficulty in land reclamation, more hoisting operations, and large investment in equipment. Contents of the invention [0003] Aiming at the above problems, the present invention provides tensioning e...
