Description

7# Turnout Prestressed Concrete Turnout Sleeper, Backing Plate and Connecting Parts

technical field

The utility model relates to railway equipment, in particular to a 7# turnout prestressed concrete turnout sleeper, a backing plate and a connecting piece.

Background technique

There are many small turnouts in industrial, mining and metallurgical enterprises, such as 6#, 7#, 9# and non-standard 8#, among which 7# turnout occupies the main position. At present, all 7# turnouts are connected by wooden sleeper spikes. The main disadvantages are: The following aspects: 1. Wooden sleepers are easy to decay, have a short service life, and frequent replacement of switch sleepers; 2. The connection between rails and wooden sleepers is not stable enough with spikes, the railway is easy to deform, and the amount of maintenance increases; 3. The processing of wooden sleepers pollutes the environment and destroys forest resources. , does not meet the requirements of the concept of sustainable development; 4. In the long run, the maintenance cost of wooden sleepers is relatively high.

Utility model content

The purpose of the utility model is to overcome the defects and deficiencies in the above-mentioned prior art, and provide a 7# turnout prestressed concrete turnout sleeper, backing plate and connector.

The technical solutions adopted are:

7# Turnout prestressed concrete turnout sleepers, backing plates and connectors, including cement pillows, are characterized in that an iron backing plate is laid on the top surface of the cement sleeper, and an iron backing plate is placed between the top surface of the cement pillow and the iron backing plate. There is a rubber pad under the board, the iron backing board and the rubber pad under the board are fixed on the cement sleeper by bolts, the rail is laid on the top surface of the iron backing board, the gauge block is placed on the bottom of the rail, and the center of the gauge block is set A screw hole, a screw is pierced in the screw hole, an elastic strip is arranged on the screw, the screw is tightened on an iron seat, and the iron seat is welded and fixed on the iron backing plate.

The utility model has the advantages of simple structure, long service life, difficult deformation of the railway, less maintenance, resource saving and the like.
