Abstract

The utility model discloses a fastener for a rail, which comprises screw spikes symmetrically arranged at both ends of the rail, wherein, each screw spike is provided with a spring matched with the outer margin of the rail, the bottom of the springs is provided with a baffle seat. The utility model is characterized in that each spring forms a plate type closed ring shape; a cavernous body is arranged on one side of the rail outside the springs; the upper part of the springs is provided with anti-loosening nuts. Due to the adoption of such a structure, the utility model has the advantages of material saving, low cost, low maintenance cost, low requirement, convenient installation and adjustment, safety, reliability, high intensity, high elasticity degree, high fastening pressure, etc.

Description

Fastener for rail

The utility model relates to a kind of rail servicing unit, relates in particular to a kind of Fastener for rail that rail, city underground etc. use that is used for.

What present track clamping device generally adopted is elastic bar fastener, i.e. the various model gauge aprons of rolling of sectional iron, spring, baffle plate base, spiral screw spike, general nut, pad are formed.Screw spike and nut cooperate and spring is pressed on the gauge apron and clamps track.This device bullet journey is low, buckle press is little, corrosion-resistant, wear-resistant degree is low, the adjustment trouble is installed, manufacturing cost height, maintaining requirement, expense height, the track clamping device requirement after incompatible present railway construction and the speed-raising.

The purpose of this utility model just is to provide the high-elastic fastener of track of a kind of simple in structure, materials province, low cost of manufacture, maintaining requirement, the reliable high strength of expense lower security, high-elastic journey, high buckle press.

The purpose of this utility model can realize by following measure:

The utility model comprises the screw spike that is symmetricly set on the track both sides, on each screw spike, be mounted with the spring that matches with the track outer rim, be provided with the plate washer seat in the bottom of spring, spring is board-like closed annular, outside spring, be positioned at track one side and be provided with cavernous body, be mounted with locknut on the top of spring.

The utility model offers at least two symmetrical annular grooves in the periphery of spring, and the quantity of groove should be determined according to specific requirement.Ring spring one end offers the lipostomous of corresponding connection with the other end, and this its latter end of an end that contains lipostomous is a rectangular shaped, and its other end is provided with and the corresponding fastening platform of lipostomous.Certainly, also both ends of the spring directly can be welded together or makes integral structure.The cavernous body bottom should be full of spring and track contact position groove.

The utility model is owing to adopt locknut, tabular or have an annular closing spring of groove, and be provided with cavernous body, should fill with lubrication oil in the cavernous body body, make to the utlity model has that materials are economized, cost of manufacture is low, the maintaining expense, require low, install easy to adjust, have safety, reliable, intensity is high, plays the journey height, the buckle press advantages of higher.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A echelon sectional view of the utility model Fig. 1.

Fig. 3 is the B-B sectional view of the utility model Fig. 1.

Fig. 4 is the C-C echelon sectional view of the utility model Fig. 2.

The utility model is done to describe in detail below in conjunction with drawings and Examples:

As shown in the figure: the utility model comprises the screw spike 4 that is symmetricly set on track 1 both sides, on each screw spike 4, be mounted with the spring 5 that matches with track 1 outer rim, be provided with plate washer seat 9 in the bottom of spring 5, spring 5 is board-like closed annular, outside spring 5, be positioned at track one side and be provided with cavernous body 2, be mounted with locknut 3 on the top of spring 5.Offer at least two annular grooves 10,11 of symmetry in the periphery of spring 5.Ring spring 5 one ends offer the lipostomous 13 of corresponding connection with the other end, and this its latter end of an end that contains lipostomous is a rectangular shaped, and its other end is provided with and the corresponding fastening platform 12 of lipostomous.Concretely, offer two corresponding installing holes on the board-like closed annular structure of spring 5, screw spike 4 promptly is inserted in two installing holes.The lower end of screw spike 4 is fixed in the fixative 6 of railway roadbed 8, and label 7 is the rubber mat plate under the rail.

Operating principle of the present utility model is: earlier spring is installed on the screw spike in two installing holes, the spring openend should be positioned at track inferior horn place, when locknut be embedded in screw spike in the railway roadbed and cooperate when tightening, make the special shape camber of spring, produce stronger buckle press, and be to produce buckle press along the ring surface of spring and track contact position, with bigger contact area with track being fixed on the rubber mat plate on the railway roadbed tightly.In addition, the spring openend produces top power to track inferior horn place.When bullet train by the time, the spring of track both sides will produce bigger bullet journey and stress, be satisfied with bullet train for a long time by after the set back ride comfort that guarantees track and normally moving.Adopt the spring of band groove and reduce spillage of material, reduce manufacturing cost, and form the oil storage die cavity in order that improve spring rate.Cavernous body should be filled with lubrication oil, and lubrication oil infiltrates to spring and track contact position from groove, and the upper surface of cavernous body should harden, to stop foreign material.The effect that cavernous body is annotated lubrication oil is in the medium-term and long-term contact position of lubricating track and spring of the process of camber of spring, make train by the time reduce deformation drag, reduce wear, and guarantee that track and spring laterally, vertically relatively move flexibly, with adapt to track repeat reset and prolong transverse extension and shortening because of what rising-heat contracting-cold caused, and keep function constant.The duricrust that one deck is harder above the cavernous body is parallel with the spring upper surface, in order that guarantee to avoid distributing and preventing foreign material from entering gap between track and the spring and stuck spring makes it to lose efficacy and had an accident of oil.The utility model also can make track outside spring thickness greater than the inboard spring thickness of track with adapt to train by the time wheel to the outward pressure of track, guarantee that normal operation also reduces the material consumption.
