CN2067292U - Adjustable rail fastening clip - Google Patents

Abstract

The utility model relates to an adjustable rail fastening clip for trackways. The adjustable rail fastening clip is composed of a screw spike, a nut, a flat washer, a spring washer, a buckle plate, an iron seat, an insulation buffering spacer and an insulation buffer pad, wherein, the buckle plate forms a quadrilateral-shaped body or a hexagonal-shaped body and can be double-faced use. Two and three adjustable sides are respectively provided, which can adjust the rail gauge to the permitted dimension. The adjustable rail fastening clip with simple structure and low cost can avoid using spare parts and can reduce the work load of the serviceman at the time of on-site adjustment.

Description

Adjustable rail fastening clip

The utility model relates to the rail fastening of using on a kind of rail track.

On rail track, because the rail side is stressed, cause rail wear, the rail gauge is increased, need to adjust gauge with fastener, the rail clip that adopts at present on the rail track, have only a packet size, when adjusting gauge, need have eight other buckles of level, selective and change usefulness, bring a lot of inconvenience to the scene.

The purpose of this utility model is to overcome weak point of the prior art and a kind of spare part of need not using is provided, and only depends on fastener self to adjust the adjustable rail fastening of gauge.

The purpose of this utility model is achieved in that

The anchoring screw spike is laid liner and insulated buffer plate, and chimb is fastened concrete sleeper, prevent that backing plate from moving and misplace, place the buffer insulation pad, should make pad and concrete sleeper support rail groove face and shoulder block closely connected, the iron seat is installed then, push down pad, number fastens rail with one side of buckle corresponding size in accordance with regulations, and buckle is contained on the iron seat, loads onto spring washer and plain washer at last, fastening nut makes buckle fastening rail.The buckle of one one steel rail is installed earlier, and the buckle of another one steel rail is installed in the back.The shape of buckle can be made the hexagon body, the two sides all can be used, it is adjustable side that every face has three chimbs, stamp number respectively, each chimb size differs 2 millimeters, can form other gauge of 11 levels with a limit of the hexagon buckle of another one steel rail on the same sleepers regulates, both can make the rail gauge transfer to 1451 millimeters on permissible value gauge by 1435 millimeters standard gauges, the shape of buckle also can be made cubic body, it is adjustable side that every face has two chimbs, stamp number respectively, each chimb size differs 3 millimeters, can form other gauge of 7 levels with a limit of the buckle of another one steel rail on the same sleepers and regulate, can make the rail gauge transfer to 1451 millimeters of permissible values by 1435 millimeters of standard gauges.

The material of adjustable buckle can be a malleable cast iron.

The utility model has following advantage compared to existing technology:

1, adjusts gauge and can remove acknowledgment copy from, alleviate the line maintenance personnel labor intensity

2, save raw material

3, technology is easy, and cost is low

Further specify the utility model below in conjunction with accompanying drawing

Anchoring screw spike 5, lay liner and insulated buffer plate 10, and chimb fastened concrete sleeper 1, prevent that insulated buffer plate 10 from moving and misplace, place buffer insulation pad 2, should make buffer insulation pad 2 closely connected with the support rail groove face and the shoulder block of sleeper 1, iron seat 3 is installed is then pushed down buffer insulation pad 2, number fastens rail 9 on one side with buckle 4 corresponding sizes in accordance with regulations, and buckle 4 is contained on the iron seat 3, loads onto spring washer 8 and plain washer 7 at last, fastening nut 6, make buckle 4 fastening rail 9, the fastener of an one steel rail is installed earlier, the fastener of another one steel rail on the same sleepers is installed in the back.The shape of buckle 4 can be made the hexagon body, two-sided use, it is adjustable side that every face has three chimbs, stamps number respectively, the size on every limit differs 2 millimeters, one side on every limit and the same sleeper hexagon buckle of another one steel rail form one group, adjustable 11 grades; The shape of buckle 4 also can be made the quadrangle body, two-sided use, and it is adjustable side that every face has two chimbs, stamp number respectively, the size on every limit differs 3 millimeters, one side on every limit and the same sleepers quadrangle body buckle of another one steel rail form one group, adjustable 7 levels.Two kinds of buckles all can make the rail distance transfer to 1451 millimeters of permissible values by 1435 millimeters of standard gauges.
