Description

Technical Field

[0001] The utility model specifically relates to the technical field of rail fasteners, in particular to a rail fastener which is easy to replace. Background Art

[0002] Railway tracks, also known as rails, tracks, and tracks, are used on railways and work with switches to allow trains to travel without turning. Tracks are usually made up of two parallel steel rails. The rails are fixed on sleepers, and under the sleepers is ballast. Rails made of steel can bear greater weight than other materials. Sleepers are also called sleepers or road sleepers. Their function is to distribute the weight of the rails, keep the rails fixed, and maintain the track gauge of the rails. Generally speaking, the bottom of the track is ballast made of gravel. Ballast, also known as ballast, crushed stone or roadbed, provides elasticity and drainage for the track. Rails can also be laid on a concrete base (quite common on bridges) or even embedded in concrete.

[0003] When installing the track, it is necessary to use track clips to fix the components on the track to prevent the track from loosening or shifting. In order to ensure the stability of the track, the connection of the track clips is generally complicated. However, the track is always exposed to the open air environment. After a long period of wind and sun, the components of the track will be damaged. The track will also wear out after long-term use. At this time, in order to ensure safety and normal use of the track, it is necessary to replace the track components in time. However, general track clips are very laborious and troublesome to disassemble, which seriously reduces the efficiency of track component replacement. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-9 In the embodiment of the utility model, a track fastener that is easy to replace includes a bottom plate 6 and a pressure block 1. The bottom plate 6 as the track support body is rectangular, and an inclined surface is provided in the middle of the top of the bottom plate 6. A crossbeam 13 is placed on the inclined surface of the bottom plate 6;

[0030] There are two pressing blocks 1 as rail clips, and the two pressing blocks 1 are respectively located on both sides of the crossbeam 13;

[0031] Furthermore, the two pressing blocks 1 are both in an inverted concave shape, and the protrusion length of the two pressing blocks 1 on one side close to the cross beam 13 is smaller than the protrusion length on the other side;

[0032] The middle of the two pressing blocks 1 is sleeved with a first screw rod 4, the upper ends of the two first screw rods 4 are threadedly connected with nuts 2, and a first spring 3 is provided between the nuts 2 and the pressing blocks 1 on the same side, and the two first springs 3 are sleeved on the outside of the two first screw rods 4 respectively;

[0033] The top of the pressing block 1 is symmetrically welded with side ridges 7, and the two side ridges 7 are respectively located at the two ends of the top inclined surface of the pressing block 1, and the heights of the two side ridges 7 are different; a slot 12 is provided in the middle of the two side ridges 7, and a positioning block 5 is clamped in the two slots 12; the tops of the two positioning blocks 5 are respectively welded to the bottoms of the two first screws 4;

[0034] The four corners of the bottom plate 6 are each provided with a threaded hole 8 , and the plurality of threaded holes 8 all pass through the bottom plate 6 ; the inner sides of the plurality of threaded holes 8 are all threadedly connected with a second screw rod 10 .

[0035] By adopting the above technical scheme, firstly, the two positioning blocks 5 are respectively placed in the slots 12 of the two side ridges 7. The shapes of the two slots 12 are the same as those of the two positioning blocks 5. After the positioning blocks 5 enter the slots 12, the slots 12 can fix the positioning blocks 5 so that the positioning blocks 5 will not be displaced or rotated. At this time, the pressing block 1 is sleeved on the first screw 4 welded to the positioning block 5, and then the nut 2 is screwed. As the nut 2 continues to descend, the nut 2 can compact the first spring 3, and the first spring 3 compacts the pressing block 1, so that the pressing block 1 fits tightly with the side ridge 7. While the pressing block 1 fits tightly with the side ridge 7, the two pressing blocks 1 can also press the bottom sides of the cross beam 13, thereby fixing the various components of the track. The slots 12 can prevent the buckle from shaking, and reducing the shaking of the buckle can prevent the buckle from loosening, thereby achieving the purpose of the buckle fixing the track components for a long time. When the buckle needs to be disassembled, it is only necessary to screw the nut 2 so that the pressing block 1 no longer presses the bottom plate 6 and the cross beam 13, which is simple and convenient.

[0036] In this embodiment, the outer sides of the plurality of second screw rods 10 are sleeved with second springs 11, and the plurality of second springs 11 are respectively located between the nuts of the plurality of second screw rods 10 and the bottom plate 6;

[0037] The bottom plate 6 is provided with grooves in the middle of both sides, and the two ends of the cross beam 13 are provided with grooves, and the two grooves of the cross beam 13 correspond to the positions of the two grooves of the bottom plate 6 respectively;

[0038] The two grooves of the bottom plate 6 are fixedly connected with connecting plates 9 by bolts. The upper ends of the two connecting plates 9 are respectively located in the two grooves of the cross beam 13, and the upper ends of the two connecting plates 9 are fixedly connected to the two ends of the cross beam 13 by bolts.

[0039] By adopting the above technical solution, the inclined surface arranged on the top of the base plate 6 fits with the cross beam 13, so that the cross beam 13 is also arranged at an incline, and the track components are symmetrically arranged, so the two cross beams 13 are distributed in an eight-shaped shape. When the two eight-shaped cross beams 13 carry heavy objects such as trains, their carrying capacity is stronger and they will not easily break or move; the two ends of the cross beam 13 are fixedly connected to the two sides of the base plate 6 by connecting plates 9 respectively, and the two connecting plates 9 can further increase the stability of the connection between the cross beam 13 and the base plate 6, thereby increasing the overall stability of the track.

[0040] The working principle of the utility model is as follows: first, two positioning blocks 5 are placed in the slots 12 of the two side ridges 7 respectively. The shapes of the two slots 12 are the same as those of the two positioning blocks 5. After the positioning blocks 5 enter the slots 12, the slots 12 can fix the positioning blocks 5 so that the positioning blocks 5 will not be displaced or rotated. At this time, the pressing block 1 is sleeved on the first screw rod 4 welded to the positioning block 5, and then the nut 2 is screwed. As the nut 2 continues to drop, the nut 2 can compress the first spring 3, and the first spring 3 Compact the pressing block 1 so that the pressing block 1 fits tightly with the side ridge 7. When the pressing block 1 fits tightly with the side ridge 7, the two pressing blocks 1 can also press the bottom sides of the cross beam 13, so as to fix the various components of the track. The card slot 12 can prevent the buckle from shaking. Reducing the shaking of the buckle can prevent the buckle from loosening, so as to achieve the purpose of fixing the track components for a long time. When the buckle needs to be removed, it is only necessary to screw the nut 2 so that the pressing block 1 no longer presses the bottom plate 6 and the cross beam 13. It is simple and convenient.

[0041] The inclined surface set on the top of the base plate 6 fits with the cross beam 13, so that the cross beam 13 is also set at an incline, and the track components are symmetrically arranged, so the two cross beams 13 are distributed in an eight-shaped shape. When the two eight-shaped cross beams 13 carry heavy objects such as trains, their carrying capacity is stronger and they will not easily break or move. The two ends of the cross beam 13 are fixedly connected to the two sides of the base plate 6 through the connecting plates 9 respectively. The two connecting plates 9 can further increase the stability of the connection between the cross beam 13 and the base plate 6, thereby increasing the overall stability of the track.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
