Description
Technical field
The present invention relates to a kind of railroad rail anchorage clip.
Background technology
In GB 2199875B, its disclosure is included in herein as a reference.In this application, the applicant discloses a kind of elasticity railroad rail anchorage clip 90, as shown in Fig. 1 and Fig. 2 of accompanying drawing.A kind of metal bar of anchorage clip 90 usefulness is made, and described metal bar is so crooked, promptly along metal bar from its end to end, at first having one is straight first 10 basically; Be the second portion 20 of a bending then; Be one to be straight third part 30 basically then, the axis of the axis of described third part 30 and first 10 forms one basically greater than 45 ° angle, and above-mentioned two axis are arranged in same plane; Be the 4th a crooked in the other direction part 40 then; Be one the 5th part 50 then; Be another the 6th crooked in the other direction part 60 then; Be one the 7th part 70 at last, described the 7th part 70 forms the toe of anchorage clip 90.When observing from the top, it seems that the 5th part 50 and the 7th part 70 be on the opposite side of third part 30.
In use, anchorage clip 90 is placed on the sleeper 100 and the 7th part 70 is placed on the footing 120 of a rail 110, first 10 stretches in the circular blind hole 140 of sleeper 100, and a screw spike 130 inserts in the sleeper 100 between third part 30 and the 5th part 50.Make anchorage clip 90 remain on the appropriate location by this way, in described appropriate location, the toe 70 of anchorage clip 90 is pressed against on the rail foot 120, so that unclipped railway lines 110, and the second portion 20 that makes anchorage clip 90 and the side direction of third part 30 partly contact the edge of rail foot 120, remain unchanged so that guarantee gauge, promptly so that prevent rail 110 shifted laterallys.
The applicant has realized that now and can improve this anchorage clip 90.
Summary of the invention
According to one embodiment of the present of invention, a kind of elasticity railroad rail anchorage clip is provided, anchorage clip is a kind of metal bar, described metal bar is so crooked, promptly along metal bar from its end to end, at first having one is straight first basically; Be the second portion of a bending then; Be one to be straight third part basically then, the axis of described third part and the straight line of first form one basically greater than 45 ° angle, and above-mentioned two axis are arranged in same plane; Be the 4th a crooked in the other direction part then; Be one the 5th part then; Be another the 6th crooked in the other direction part then; Be one the 7th part at last; Such structural form can make anchorage clip be placed in an ad-hoc location, so that third part be level and first extend downwards, and when observing from the top, it seems that the 5th part and the 7th part be opposite side in third part, this anchorage clip is characterised in that: first is configured as and comprises that one has one along the zone on the cylindrical substantially surface that its whole length is extended and the part of a longitudinal extension, and above-mentioned longitudinal extension partly has the surface than the less protrusion in cylindrical substantially surface of first.
The air pressure resistance has been got rid of by the first that makes anchorage clip like this, and the first of anchorage clip more easily can be inserted in the blind hole of sleeper and take out from this blind hole.
Preferably, the surface of longitudinal extension part is flat basically.
Alternatively, the surface of longitudinal extension part is recessed into.
Usually, the rod of formation anchorage clip has rounded substantially cross section.Be pressed against on the rail edge to prevent that track side is when mobile, therefore second of prior art anchorage clip only forms line with the planar edge of rail with third part and contacts, the consequently high and generation wearing and tearing too early of contact pressure, form a flat in these zones on anchorage clip simultaneously, and therefore cause some small gauges to broaden.
Therefore, preferably, in using a kind of anchorage clip of the present invention, at least a portion of second portion and at least a portion of third part are so made, promptly on the surface that has the substantially flat that contacts with rail on its side zones separately when using anchorage clip.
Therefore, the flat surfaces and the contact pressure between the rail edge of anchorage clip second and third part are much smaller, have significantly reduced the wearing and tearing on these zones of anchorage clip.
It is desirable to, second portion be smooth surface basically with third part be that smooth surface is connected basically.
When the longitudinal extension of first partly has one is smooth when surperficial basically, this surface preferably with second portion be that smooth surface is connected basically.

Fig. 8 illustrates the phantom drawing of the partial cut-out of a part that comprises the railroad rail fastening assembly of implementing a kind of anchorage clip of the present invention;
Fig. 9 (A)-Fig. 9 (D) is used to illustrate the view of making the method for implementing a kind of anchorage clip of the present invention; And
Figure 10 illustrates another kind of alternative enforcement anchorage clip of the present invention.
The specific embodiment
As shown in Fig. 3 to Fig. 9, implementing a kind of railroad rail anchorage clip 9 of the present invention is made by a kind of like this metal bar, i.e. other end B from an end A of rod to rod comprises that one is that the second portion 2, of straight first 1, a bending is that the 4th part 4, one the 5th part 5 of straight third part 3, a bending, the 6th part 6 and of a bending form the 7th part 7 of anchorage clip 9 toes basically basically.The longitudinal axis of first 1 and third part 3 is arranged in same plane, and the axis shape of the axis of third part 3 and first 1 at an angle.It is 90 ° that angle [alpha] is shown in this embodiment, but α can be basically greater than any angle of 45 °.
As in the prior art, keep anchorage clip 9 like this, so that the anchorage clip toe is pressed against on the rail foot 12 by a screw spike 13 that is screwed in the sleeper 15, the ailhead of this screw spike 13 is pressed against on the third part 3 and the 5th part 5 of anchorage clip.
Preformed plane 2A, 3A on anchorage clip 9 second portions 2 and the third part 3 are used to prevent that gauge from broadening, and the cross section of these parts is circular and grinds a plane on these zones else if, gauge then can take place in these zones broaden.These preformed planes also can advantageously be applicable to the rail clip of on its downward supporting leg neither one plane or groove.
A kind of anchorage clip 9 with plane 1A, 2A and 3A can be made to the method shown in Fig. 9 (D) with Fig. 9 (A).In Fig. 9 (A), a kind of shape that prebends is flatly supported, and plane 1A, 2A and 3A form by being extruded along the arrow A direction.Vertical support portion is divided the anchorage clip (Fig. 9 (B)) of moulding then, and with a power in the direction of arrow B (Fig. 9 (C)) be applied on the part of the 7th part 7 to be formed, so that this part is bent to its net shape, thereby form a kind of enforcement anchorage clip of the present invention (Fig. 9 (D)).
To shown in Figure 7, the size of implementing a kind of typical anchorage clip of the present invention is as follows: l=143mm, w=76mm, a=75mm as Fig. 4 in the accompanying drawing, b=97mm, c=46mm, d=14mm, e=30mm, f=45mm, g=13mm, r1=8mm, r2=12.5mm and α=90 °.
