Abstract

A prestressed concrete switch tie, base plate and connector combination for No.7 switches comprises a cement tie and is characterized in that an iron base plate is laid on the top of the cement tie, a rubber pad is disposed between the top of the cement tie and the iron base plate, iron rails are laid on the top of the iron base plate, a gauge block is pressed at the bottom of each iron rail, the center of each gauge block is provided with a screw hole, a screw is entered into each screw hole, an elastic plate is disposed on each screw, each screw is tightened on an iron seat, and the iron seats are fixedly welded on the iron base plate. The prestressed concrete switch tie, base plate and connector combination for No.7 switches has such advantages that structure is simple, service life is long, railways deform less easily, maintenance is low and resources are economized.

Description

7# track switch PRESTRESSED CONCRETE TURNOUT SLEEPERS, backing plate and connector

Technical field

The utility model relates to railway equipment, particularly relates to 7# track switch PRESTRESSED CONCRETE TURNOUT SLEEPERS, backing plate and connector.

Background technology

The small size track switch of industrial and mineral smelter is more, such as 6#, 7#, 9# and off-gauge 8#, wherein 7# track switch in the highest flight, all 7# track switches are all adopted sleeper railway spike connected mode at present, its shortcoming mainly contains following several respects, and 1, sleeper is apt to rot, application life is short, switch tie is changed frequent; 2, to adopt railway spike to be connected stable not for rail and sleeper, and railway is out of shape easily, the maintenance capacity increasing; 3, sleeper processing pollution environment destroys the forest reserves, does not meet the requirement of sustainable development view; 4, calculate in the long run, the large maintenance cost of sleeper is higher.

The utility model content

The purpose of this utility model is exactly defective and the deficiency that exists for overcoming above-mentioned prior art, and a kind of 7# track switch PRESTRESSED CONCRETE TURNOUT SLEEPERS, backing plate and connector are provided.

The technical scheme that adopts is:

7# track switch PRESTRESSED CONCRETE TURNOUT SLEEPERS, backing plate and connector, comprise cement sleeper, it is characterized in that being equipped with iron chair on the end face of described cement sleeper, be equipped with rubber cushion under the plate between the end face of cement sleeper and the iron chair, rubber cushion is bolted on the cement sleeper under iron chair and the plate, be equipped with rail on the end face of iron chair, the bottom of rail is pressed and is equipped with track gauge block, the center of track gauge block is provided with screw, be equipped with screw in the screw, be equiped with spring on the screw, screw means is on an iron seat, and the solid welding of iron seat is on iron chair.

The utlity model has simple in structure, long service life, railway is not yielding, maintenance capacity adds little, the advantage such as economize on resources.

Description of drawings

Fig. 1 is structural representation of the present utility model.
