Abstract
The utility model discloses a positioning structure for an anchor backing plate of a ballastless track plate used for manufacturing a railway prestressed concrete ballastless track plate. The positioning structure comprises a cone frustum-shaped anchor socket which is fixed on an end and side plate; the front end of the anchor socket is provided with an anchor backing plate; a central hole punched and arranged on the anchor backing plate is internally provided with a prestressed tension steel bar with screw thread at the end; the prestressed tension steel bar is connected with a pretensioning bolt through the screw thread at the end of the prestressed tension steel bar; a central thread hole is arranged outside the anchor backing plate which is connected with a fastening thread sleeve with hexagonal square heads at the outside end through the central thread hole; and the front part of the fastening thread sleeve is provided with a positioning convex plate which is matched with the end face of an inner hole of the cone frustum-shaped anchor socket. By adopting the positioning structure of the anchor backing plate in which the fastening thread sleeve is connected with the anchor backing plate through the central thread hole, the assembling of the anchor backing plate is convenient, and the connecting and positioning are reliable.
