Description

The present invention relates to rail fastening units.

In documents WO 93/12294, WO 93/12295, and WO 93/12296, the present applicants disclosed a rail fastening system in which a rail fastening clip is inserted into the rail from the side and can be held in the clip anchor (shoulder) in a “pre-assembled” position or “storage” position when the toe of the clamp is not pressed against the rail. This allows, even during production, to install the clamps on the sleepers in a pre-assembled state so that when the sleepers are delivered to the installation site, the clamps only have to snap after laying the rails. In addition, when tinning of the rails is required in the future, the clamp can be disconnected from the rail and returned to the previously assembled position. These clamps are sometimes called “on / off” clamps. A similar bonding system has proven successful, however, applicants would like to make improvements to certain aspects of its manufacture and operation.

In the previous application, which had not yet been published at the time of filing this application, the applicants disclosed a shoulder that did not have the properties of the meshing clamp in the lower part of the walls of the shoulder. Accordingly, for the heel of the clamp, it is necessary to provide an additional clamping element.

According to a first aspect of the present invention, there is provided a part for use in a rail fastening assembly, the assembly includes a clamp for fastening a railway rail, consisting of a first part for pressing a rail rail and an anchor fastening device for a rail rail clamp to hold a rail rail clamp, wherein the part consists of the first element adapted to receive lateral load from the rail, located between the essentially vertical face of the anchor device Nia rail clip and base side of an adjacent railway rail assembly during use; the part also consists of a second element for receiving the second bearing part of the clamp of the rail; the first and second elements of the part are spaced from each other and are connected by a connecting element. Thus, the part can perform the function of the absent calcaneal bearing parts of the anchoring device. In addition, if the heel bearing parts of the part require replacement due to wear or damage, this can be done easily and quickly. If you need to adjust the characteristics of the node, the part can also be easily replaced with another part, the first element of which has a greater or lesser thickness and / or the second element has a greater or lesser height. In addition, due to the connection of the first and second elements, the number of removable parts that would need to be installed and assembled at the sleeper factory and repaired under operating conditions is minimized.

The first element is preferably designed to transfer lateral load from the rail to the rail clamp anchor attachment. Thus, the first element acts as a side pillar.

It is desirable that the connecting element includes at least one elongated link located between the first and second elements. Since the elongated link does not absorb the lateral load from the rail, relatively small and thin links can be used to reduce the cost of materials.

The connecting element preferably connects the first and second elements of the part so that when the first element is between the anchoring device and the rail sole, the connecting element is located around the edge of the anchoring device.

In a preferred embodiment, the connecting element consists of two elongated links, one elongated link is located between the corresponding first points on the first and second elements, and the other elongated link is located between the corresponding second points on the first and second elements. If the area is limited by connected elongated links, and the shapes of the first element and the second elements allow the rail clamp to be anchored, then the part can be installed in the rail fastening system by simply pushing the part through the top of the anchor. It is desirable that the part fits tightly into the base of the anchoring device.

The part may be predominantly one-piece, preferably from a material with a wear-resistant surface that meets the requirements of both the first and second elements. Alternatively, if necessary, one of the parts can be injection molded from two different materials. If the first element of the part is used as an insulator, then the first element should at least be made of electrical insulating material. In any case, the part is preferably made of plastic, for example nylon.

The second element preferably includes at least one upwardly directed structure having a surface for clamping thereon. It is desirable that the second element had two spaced apart seats for clamping, each of which would have a receiving surface for clamping. Clamp seats can be formed by corresponding interconnected structures. If the part is approximately rectangular in shape, the seats can be located respectively in the adjacent corners of the part. It is desirable that each seat in cross section has a substantially L-shape when viewed substantially perpendicular to the clamp receiving surface.

In the first element, there may be at least one part overlapping a part of the anchoring device. In this case, this part may be overlapped by a clamp for fastening the rails when the clamp is held in the anchoring device.

When a part of an embodiment of the present invention is used in conjunction with a rail rail clip anchor device, the first part element is adjacent to the substantially vertical face of the rail anchor device facing the bottom of the rail when the device is in use and the second element is opposite the side of the anchoring device with respect to said substantially vertical face. The second element acts as an element of the foot of the heel of the anchoring device, on which the element of the heel of the clip rests to fasten the rail when the device is used.

According to a second aspect of the present invention, there is provided an insulating plate for a rail clamp anchor device consisting of a head part and a liner starting from the head part and extending into the concrete sleeper when the anchor device is used, the plate is designed to pass under the head part when the shank of the device is installed in concrete sleepers, thereby preventing concrete from leaking into the head of the device, and subsequently remain on the surface sleepers.

The plate is preferably made of plastic, for example polypropylene.

The insulating plate can be used to seal the holes in the mold cell in the manufacture of sleepers and to prevent the influx of concrete into the head of the shoulder. In use, the insulating board is actually glued to the top of the reinforced concrete sleepers, so that its front part becomes flush with the upper surface of the concrete at the top of the sleepers.

According to a third aspect of the present invention, there is provided a rail fastening assembly comprising an insulating plate according to the second aspect of the present invention, an rail clip anchor device and a part according to the first aspect of the present invention. The insulating plate engages on the shoulder and subsequently forms a flat bearing surface for the heel seat / side pillar seat.

As shown in FIG. 1A through 1N, part 7 of the first aspect of the present invention consists of a first element 71 and a second element 72. The respective ends of the first and second elements are interconnected via two elongated links 73.

The first element 71 has a shape that allows it to be used as an insulator of the side strut, and consists of a substantially vertical supporting face 78, which receives lateral loads from the rail and transfers them to the fixing device 1 of the rail clip anchor (see Fig. 3 ), as well as from the protrusion 77, which overlaps part of the device 1 anchor fastening.

The second element 72 consists of two spaced apart seats 75 for the clamp connected by an elongated link 74. The seats 75 for the clamp have corresponding L-shaped receiving surfaces 75a for the clamp. At the rear ends of each surface 75 there is a recess 75b of such a shape that simplifies mounting of the clamp.

The elongated links 73, 74 and the clamp seats 75 are essentially hollow elements, reinforced with ribs if necessary.

The plastic insulating board 2 of the second aspect of the present invention will be described below with reference to FIG. from 2A to 2P. The insulating plate 2 has a first main face 20, which is located at the very top when the plate 2 is installed on top of the sleepers and the second main face 21, the opposite of the first. The insulating plate 2 has a substantially rectangular shape with a cutout along one side 22, forming brackets 23, providing a seal at the corners of the shoulder 1, located above the plate 2 in the cutout 22. The cutout 22 has a beveled end 22a, mating with the corresponding beveled end on the rear face 15 the shoulder 1. The neckline 22 also has a recess 24 for receiving double shanks of the shoulder 1 (see figure 3).

An example of an anchor device (shoulder) compatible with the part of the first aspect of the present invention and the insulating plate of the second aspect of the invention will be further discussed with reference to FIGS. 3A and 3B. The anchoring device 1, shown in Fig. 3, consists of a head part 1A, from which two shanks 1B, laid down in a reinforced concrete sleeper, are laid down under it. Alternatively, Y-shaped shanks may be used.

The head part 1A of the anchoring device 1 consists of two spaced apart walls 10, interconnected at one of the ends of the head part 1A, at the base of the walls 10, by the connecting element 14. The upper surface of the connecting element 14 is inclined downward and forms a ramp 140, then how the front surface of the connecting element 14 forms the front face 12 of the shoulder 1. The ends of the walls 10 from the front end of the head part 1A are connected to the front face 12 of the shoulder by curved elements 13.

The upper parts of the walls 10 expand externally, forming respective surfaces 11 for engaging the clamp, on which there is a downward protrusion 110 for engaging the clamp. The clamp engaging surfaces 11 have a slope extending from the back of the shoulder 1 to the front of the shoulder 1, for biasing toward the shoulder of the clamp for fastening the rail. The front face 12 of the shoulder 1 has protrusions 120 for engagement with the mold for casting sleepers to set the shoulder in the mold at the correct height before pouring concrete. Alternatively, instead of two protrusions 120, one protrusion can be used. In the shoulder 1 there is a rear face 15, opposite to the front face 12.

Returning again to FIG. 1A to 1N, there are vertical projections 27 in the main face 20 of the plate 2 for pairing with the corresponding elements 127 in the lower part of the shoulder 1 to hold the plate 2 on the shoulder 1 (and vice versa) before the plate 2 and the shoulder 1 are installed in concrete sleepers. The main face of the plate 2 also has holes 26 for forming the inner part of the protrusions 27 in the manufacture of the insulating plate 2.

The shoulder 1 is held and secured in the injection mold by a mechanism pulling the head portion 1A protruding through the bottom of the injection mold. The protrusions 120 on the shoulder 1 are designed to reduce such a pulling force applied to the insulating plate, which, otherwise, may become uneven.

On the first main face 20 of the plate 2 there is also an elongated limb 25 located along a part of the rear edge of the plate 2, which helps to hold the part 7, when using the part, the elongated link 74 of the part 7 is located between the bend 25 and the protrusions 27.

In the second main face 21 of the slab 2, forming the lower side of the slab, there are many intersecting ribs 28, forming numerous grooves 29. When the slab is installed on the upper surface of the concrete sleepers, these grooves 29 are filled with concrete, providing additional reinforcement of the slab 2 and thus reducing the amount of material used, and therefore the cost of manufacturing the plate 2.

An assembly for fastening railway rails using the elements described above will be discussed later with reference to FIG. from 4A to 4C. The assembly of FIG. 4A to 4C for fastening a rail rail 5 consists of a shoulder 1 described with reference to FIG. 3, a clip 3 for fastening a rail, a part 7 according to the first aspect of the present invention described with reference to FIG. 1, an insulating plate 2 according to the second aspect the present invention described with reference to figure 2, as well as pillows 4 under the rail. It should be understood, although not shown in FIG. 4A to 4C, which, when used, the shanks 1B of the shoulder 1 are laid in concrete sleepers 6. The insulating plate 2 is also laid in concrete sleepers 6 so that the upper face of the insulating plate 2 is flush with the upper surface of the concrete sleepers 6. Clamp 3 can be inserted into the shoulder 1 by introducing the non-rounded ends of the shoulders 31, 37 into the gaps between the upper surfaces 75a of the seats 75 of the clamp of the part 7 and the surfaces 11 for engaging the clamp on the outer surface of the walls 10 of the shoulder 1, as well as by inserting the muscular e of the clamp 3, with the installed insulator 34a, into the space between the inner surfaces of the walls 10 of the shoulder 1 so that the toe of the clamp 3, through the insulator 34a, is pressed against the ramp 140 of the shoulder 1. This position is known as “pre-assembly” or “ parking ”, in which the clamp does not press against the rail 5, but overlaps the protrusion 77 of the part 7. The interlocking properties of the mouse insulator 34a and the ramp 140 prevent the“ exit ”of the clamp 1 from the shoulder 1. Parts of the shoulders 31, 37, facing down, lie on top of the surface 75a of seats 75 clip.

Clamp 3 can be moved from a pre-assembled position (first working position) to a second working position, in which the toe portion of the clamp 3 is pressed against the sole of the rail 5, the protrusions 110 on the walls 10 are engaged with the latches on the shoulders 31, 37 of the clamp 3, and the second and the sixth elements 32, 36 (heel elements) of the clamp 3 are pressed against the upper surfaces 75a of the seats 75 of the clamp. The clamp 3 overlaps the protrusion 77 of the insulator of the side pillar of the part 7. If necessary, the clamp can be moved from this position back to the pre-assembled position if you need to dismantle or maintain the rail.

After installing the clamp 3, the toes of the clamp 3 are lifted up by the ramp 140 in the center of the shoulder 1, and the shoulders 31, 37 are lowered down, thus pushing the clamp in different directions. This allows you to further reduce the height of the node.
