Description

A wooden sleeper joint fastener

Technical Field

The utility model relates to the technical field of rail fasteners, in particular to a wooden sleeper joint fastener.

Background Art

In ordinary railways, rails are mainly fixed on wooden sleepers by means of pads and gussets. Specifically, the pads are located between the rails and the wooden sleepers, and the gussets are located on both sides of the rails. The rails are fastened from both sides at the same time, and finally the gussets are locked by bolts to fix the rails on the wooden sleepers. At the same time, in ordinary railways, there are many ways to connect two sections of rails. The most common connection method is to install joint splints on the inner and outer sides of the two sections of rails at the joint, and then use fish head bolts to penetrate and tighten the joint splints on both sides and the middle rail. The joint splint connects and clamps the two sections of rails, thereby connecting the two sections of rails together.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1-6, the utility model is a wooden sleeper joint fastener, including an iron plate 1, a gusset plate 2, a nut 4, and a T-bolt 5. The iron plate 1 is provided with a T-bolt groove 14, and the T-bolt 5 is clamped in the T-bolt groove 14. The top of the T-bolt groove 14 is provided with a gusset plate 2, and a bolt hole 16 is provided in the middle of the gusset plate 2. The T-bolt 5 passes through the bolt hole 16, and the top of the T-bolt 5 is provided with a nut 4;

An L-shaped groove 15 is provided on one side of the pinch plate 2 close to the rail 7 , and the pinch plate 2 is pressed onto the wing plate of the rail 7 through the L-shaped groove 15 .

The T-bolt 5 originally clamped on the T-block 11 is directly installed on the iron pad 1. Compared with the original structure, the T-bolt is removed and the height of the top of the T-bolt 5 is lowered. At the same time, the original buckle plate is pressed on the top of the wing plate of the rail 7 through the bottom of the convex ridge. The height difference from the top of the wing plate of the rail 7 to the nut 4 is approximately the sum of the height of the convex ridge of the original buckle plate and the height of the plate thickness of the buckle plate. The existing buckle plate 2 is pressed on the wing plate of the rail 7 through the L-shaped groove 15. The height difference from the top of the wing plate of the rail 7 to the nut 4 is approximately the plate thickness of the buckle plate 2. In this way, the height of the nut screwed on the T-bolt 5 can be further reduced, so that it is lower than the height value of the original fish bolt to avoid interference.

A first ridge 17 is provided on the bottom surface of the clip plate 2 at one end away from the rail 7, and a second ridge 19 is provided in the middle of the bottom surface of the clip plate 2. The clip plate 2, the first ridge 17 and the second ridge 19 form a groove 18, and the groove 18 is a U-shaped structure opening downward, and the bolt hole 16 is opened in the middle position of the groove 18.

The first ridge 17 and the second ridge 19 have the same extension direction as the rail 7. When the buckle plate 2 is pressed on the wing plate of the rail 7, the bottom of the first ridge 17 is pressed on the pad platform 10, and the top wall and side walls of the L-shaped groove 15 are pressed on the top wall and side walls of the wing plate respectively, thereby causing the rail 7 to be displaced in the vertical and horizontal directions.

The groove 18 makes the gusset plate 2 as a whole present a structure with support points (the first ridge 17 and the L-shaped groove 15) located on both sides, and the middle part is a suspended structure. Compared with a solid structure without the groove 18, it can save materials and enable the gusset plate 2 to cooperate with the T-bolt 5 passing through the middle position of the groove 18 to form an elastic part, which effectively alleviates the vibration impact caused by the operation of the train during long-term use and increases the service life of the gusset plate 2.

An L-shaped groove 15 is formed between the second convex ridge 19 and the bottom surface of the pinch plate 2. The L-shaped groove 15 is pressed on the top of the wing plate, and the side wall of the second convex ridge 19 is against the side wall of the wing plate.

The L-shaped groove 15 is matched with the wing plate of the rail 7, which can not only reduce the overall thickness of the gusset plate 2, but also constrain the rail 7 in the vertical and horizontal directions.

A rail bottom slope 12 for mounting the rail 7 is provided in the middle of the iron pad 1 , and pad platforms 10 are provided on both sides of the rail bottom slope 12 . A T-bolt groove 14 is provided in the middle of the edge of the pad platform 10 near the rail bottom slope 12 .

When in use, the T-bolt 5 is passed through the T-bolt groove 14, and the iron pad 1 is fixed on the wooden sleeper, and then the rail 7 is laid on the rail bottom slope 12 so that the rail 7 meets the installation requirements, and the buckle plate 2 is installed on the T-bolt 5 to constrain the rail 7 from the inside and outside of the rail 7.

The T-shaped bolt groove 14 penetrates the iron backing plate 1 , and the T-shaped bolt groove 14 is a countersunk structure with a large bottom and a small top.

The T-bolt groove 14 is used to clamp the head of the T-bolt 5. Compared with the prior art, which clamps the T-bolt 5 in the T-bolt groove on the T-shaped block 11 in a horizontal buckling manner, the existing T-bolt groove 14 reduces the complexity of the structure, which is convenient for ensuring the strength of the structure of the iron pad 1. When in use, the T-bolt 5 is directly inserted into the T-bolt groove 14 from the bottom of the iron pad 1 upward.

A flat washer 6 is provided between the buckle plate 2 and the nut 4 .

Compared with the spring washer 61 used originally, the flat washer 6 can further reduce the height of the nut 4 when being tightened on the T-bolt 5 .

Spike screw holes 13 are provided at the four corners of the iron plate 1 , threaded spikes 3 are arranged in the spike screw holes 13 , and the iron plate 1 is installed on the wooden sleeper through the threaded spikes 3 .

In the present application, the spike screw holes 13, threaded spikes 3, T-bolts 5, nuts 4, iron pads 1, wooden sleepers (and the positions of the spike screw holes on the wooden sleepers), etc., all use the original accessories. It is only necessary to remove the T-shaped blocks 11 during production and directly process the T-bolt grooves 14 at the corresponding positions on the iron pads 1, so as to facilitate the cooperation between the present joint fasteners and the original accessories, thereby minimizing the cost of accessory replacement.

Working principle: When using, first pass the T-bolt 5 upward from the bottom of the iron plate 1 through the T-bolt slot 14, then use the threaded spike 3 to pass through the spike screw hole 13 to fix the iron plate 1 on the wooden sleeper, then put the rail 7 in the rail bottom slope 12, and finally put the gusset plate 2 on the T-bolt 5, so that the L-shaped grass 15 is pressed on the edge of the wing plate of the rail 7, put on the flat washer 6, and tighten the nut 4;

Joint clamps 8 are installed on both sides of the rail 7, fish bolts 9 are passed through the rail 7 and the joint clamps 8, and the fish bolts 9 are tightened. The fish bolts 9 are located above the T-bolts and nuts 4 without interference.
