Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The invention is a set of key equipment in the production line of the ballastless track slab assembly line of the high-speed railway. The idea of ​​the invention is to realize the fully automatic operation of the tensioning equipment with hydraulic drive and control as the core.

[0026] Figure 1-4 As shown, according to the high-speed railway type III track slab design standard, longitudinal and transverse prestressed steel bars need to be placed in the track slab, and stretched to generate stress and fix it before forming. According to this, the tensioning equipment is arranged in two directions. In the figure, the longitudinal tensioning device 101 and the lateral tensioning device 103 are respectively arranged at the tensioning positions on the vertical and horizontal sides of the track plate mold 102 . The mold is transported to the stretching station a...

Abstract

Disclosed is a tensioning device on a pre-tensioning flow unit production line for a track slab on a high-speed rail, wherein ground supports (107) at a fixed height support a tensioning bed by means of universal balls; a tensioning power mechanism is fixed on the tensioning bed; track slab production line transport tracks (106) are arranged on a ground surface at inner sides of the ground supports (107); and track slab positioning supports (104) are arranged at two sides of the transport tracks (106). The device solves the problems in the prior art of low degree of automation, complex tensioning mould emplacement, and poor positioning and tensioning precision, etc.

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...
