In the time that non-fragment orbit is laid, according to the situation without tiny fragments of stone, coal, etc. railway roadbed, depart from laying-out when predicting non-fragment orbit, particularly likely make the place of non-fragment orbit rollover, mounting seat, roller is contacted with the web of the rail position of non-fragment orbit, in the time that normal non-fragment orbit is laid, floor installation to without on tiny fragments of stone, coal, etc. railway roadbed, make roller compartment act on the two sides at the web of the rail position of non-fragment orbit, owing to having designed base and roller, when pair of rollers non-fragment orbit is positioned, only carry out one side contact, no longer contacted the two sides at the web of the rail position to non-fragment orbit by two rollers simultaneously, therefore reduced the frictional force of roller and non-fragment orbit, improve the laying speed of non-fragment orbit.
The utility model has designed, and includes support, and base is set to L shaped and is provided with installing hole on an end face, and support is arranged on the position of lateral surface of another end face of base, and roller is set to and connects with support rotary type by fixed axis.
The utility model has designed, and the width of roller is set to corresponding with the height at web of the rail position, and the height that roller is arranged on base is set to corresponding with the height at web of the rail position.
The utility model has designed, and the diameter of the installing hole of base is set to corresponding with S2 screw spike.
The utility model has designed, and support is set to connect with base plug-in.
The utility model has designed, and is provided with opening roller and is set to the two sides of the opening that extends in base on the position of base and roller contact.
In the technical program, include bed plate, perpendicular support, rolling wheel support and roller, on base plate, be provided with bolt hole, bed plate adopts rectilinear connection with perpendicular support.S2 screw spike is through in the bolt hole of bed plate, makes inside bed plate and 3 in Curve Segment, in embedded sleeve barrel, to make roller aim at rail, perpendicular support is parallel to wire center.Contact with long steel rail web by roller, prevent that long rail is to the inner side of curve overturning, on bed plate, be provided with bolt hole, can place S2 screw spike, the length of bed plate setting can ensure this device to be fixed on WJ-8a iron chair and double-block type sleeper pillow shoulder, rolling wheel support is welded on perpendicular support, and roller shaft is welded on rolling wheel support.
Technique effect of the present utility model is: available S2 railway spike is firmly fixed this device on the iron chair of double-block type sleeper WJ-8a fastener; After this device is settled, roller withstands on long steel rail web, prevents that long rail is to the inner side of curve overturning, has reduced the frictional resistance that long rail pushes; This device does not highly affect the driving of long rail trailer wagon in propelling movement process; Simple and fast is installed and taken off to this device.
In the technical program, the base and the roller that contact with the single side face at the web of the rail position of tiny fragments of stone, coal, etc. track are important technical characterictic, in the technical field of the positioner of laying for non-fragment orbit, have novelty, creativeness and practicality.
Four, brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Five, detailed description of the invention
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include base 1, support 2 and roller 3, base 1 is set to L shaped and is provided with installing hole on an end face, support 2 is arranged on the position of lateral surface of another end face of base 1, and roller 3 is set to and connects with support 2 rotary types by fixed axis.
In the present embodiment, the width of roller 3 is set to corresponding with the height at web of the rail position, and the height that roller 3 is arranged on base 1 is set to corresponding with the height at web of the rail position.
In the present embodiment, the diameter of the installing hole of base 1 is set to corresponding with S2 screw spike.
In the present embodiment, the width of roller 3 is set to be not more than web of the rail height with the corresponding width that refers to roller 3 of height at web of the rail position, roller 3 be arranged on height on base 1 be set to corresponding with the height at web of the rail position refer in work progress device be in the plane highly exceed the web of the rail and do not need anti-rollover but in work progress rail paved roller and be just in time stuck in web of the rail position.
In the time that non-fragment orbit is laid, according to the situation without tiny fragments of stone, coal, etc. railway roadbed, depart from laying-out when predicting non-fragment orbit, particularly likely make the place of non-fragment orbit rollover, mounting seat 1, makes roller 3 contact with the web of the rail position of non-fragment orbit, in the time that normal non-fragment orbit is laid, base 1 is installed to without on tiny fragments of stone, coal, etc. railway roadbed, makes roller 3 compartments act on the two sides at the web of the rail position of non-fragment orbit.
