Description

Technical Field

[0001] This utility model relates to the field of railway engineering, and in particular to a fastening device for rail tracks. Background Technology

[0002] Track fastening devices are key components used to ensure the stability and safety of railway tracks. These devices are primarily used to securely fasten rails to sleepers. Existing track fastening devices typically use screws to install and fix the rails. However, due to the enormous impact and vibration generated by trains traveling at high speeds, this can lead to damage to the rail structure and increased noise. Furthermore, rails are made of metal and have a high coefficient of thermal expansion. Especially at the fixing points, the screw constraint can cause excessive deformation of the rails, thus affecting the smooth operation of trains and the safety of the track.

[0003] Therefore, it is necessary to design a rail fastening device that can buffer the rail while reducing noise transmission and preventing excessive deformation of the rail due to expansion caused by high temperature at the rail fixing point. Utility Model Content

[0004] To overcome the shortcomings of existing track fastening devices, which generate enormous impact and vibration on the rails during high-speed train operation, leading to rail structure damage and increased noise, and because rails are made of metal with a high coefficient of thermal expansion, especially at the fixing points where the screws can cause excessive deformation of the rails, thus affecting the smooth operation of the train and the safety of the track, this utility model provides a track fastening device that can buffer the rails while reducing noise transmission and preventing excessive deformation of the rails at the fixing points due to high temperature expansion.

[0005] A track fastening device includes a mounting base, a first screw, a fixing sleeve, and a locking assembly. The mounting base is detachably connected to the fixing sleeve via two first screws on the left and right sides. The fixing sleeve is provided with a locking assembly that can buffer and reduce noise transmission.

[0006] To further explain, the locking assembly includes a clamping plate, a second screw, a guide rod, a spring, a rail, a washer, and a third screw. The left and right sides of the fixing sleeve are slidably connected to two guide rods, with clamping plates connecting adjacent guide rods. The upper part of the fixing sleeve is threadedly connected to two sets of second screws, each set consisting of two screws, one in front and one behind. Each second screw engages with its adjacent clamping plate. Springs connect the guide rods to the fixing sleeve. A rail is placed on the upper side of the middle of the fixing sleeve, with the clamping plates in contact with the rail. Washers are placed on both sides of the rail. The front and rear sides of the clamping plates are threadedly connected to third screws, which engage with adjacent washers.

[0007] To further clarify, all clamping plates have a Z-shaped structure.

[0008] To further clarify, all clamping plates are made of elastic material.

[0009] To further explain, the padding strip has a U-shaped structure.

[0010] To further explain, it also includes washers; washers are connected to the upper sides of both the left and right sides of the fixing sleeve, and the second screws pass through the washers adjacent to them.

[0011] The beneficial effects of this utility model are as follows: the clamping pieces are all made of elastic material, which buffers the rail and reduces noise transmission. When the rail expands due to high temperature, the clamping pieces will deform, thereby preventing the rail from deforming too much. This achieves the effect of buffering the rail while reducing noise transmission and preventing the rail from deforming too much due to high temperature expansion at the rail fixing point.

[0017] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0018] A type of track fastening device, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a first screw 2, a fixing sleeve 3 and a locking assembly. The upper part of the mounting base 1 is detachably connected to the fixing sleeve 3 by two first screws 2 on the left and right sides. The fixing sleeve 3 is provided with a locking assembly.

[0019] like Figures 1-4As shown, the locking assembly includes a clamping plate 4, a second screw 5, a guide rod 52, a spring 53, a steel rail 6, a pad 7, and a third screw 8. The left and right sides of the fixing sleeve 3 are slidably connected to two front and rear guide rods 52. A clamping plate 4 is connected between each pair of adjacent guide rods 52. The clamping plates 4 are all Z-shaped structures and are made of elastic material. The upper part of the fixing sleeve 3 is threadedly connected to two sets of second screws 5, each set consisting of two front and rear second screws 5. The second screws 5 are engaged with their adjacent clamping plates 4. A spring 53 is connected between each guide rod 52 and the fixing sleeve 3. A steel rail 6 is placed on the upper side of the middle of the fixing sleeve 3. The clamping plates 4 are in contact with the steel rail 6. A pad 7 is placed on both the left and right sides of the steel rail 6. The pad 7 is U-shaped. The front and rear sides of the clamping plate 4 are threadedly connected to a third screw 8. The third screw 8 is engaged with the adjacent pad 7.

[0020] like Figure 3 and Figure 4 As shown, it also includes a washer 51. The upper sides of both the left and right sides of the fixing sleeve 3 are connected to washer 51, and the second screw 5 passes through the washer 51 adjacent to it.

[0021] When using this device, first install the mounting base 1 onto the rail mounting area, then fix the fixing sleeve 3 onto the mounting base 1 using the first screw 2. Next, move the clamping plate 4 outward, causing the guide rod 52 to move outward, and the spring 53 to be compressed and contracted. Then, place the rail 6 on the fixing sleeve 3, so that the rail 6 is located between the clamping plates 4. Then, place the pads 7 on the left and right sides of the rail 6. Then, release the clamping plate 4, the spring 53 returns to its original state, and causes the clamping plate 4 and the guide rod 52 to move inward, so that the clamping plate 4 contacts the rail 6. Next, pass the second screw 5 through the pad 51, and then rotate the second screw 5, so that the second screw 5 moves downward under the action of the thread and engages with the clamping plate 4. The clamping plate 4 is locked in place and fixed. Then, the third screw 8 is connected to the clamping plate 4, and the third screw 8 is rotated so that it moves downward under the action of the thread and locks with the pad 7. The clamping plate 4 is made of elastic material and is used to buffer the vibration and noise generated when the train runs on the rail 6. At the same time, the clamping plate 4 reduces the transmission of noise. When the rail 6 expands due to high temperature, the clamping plate 4 will deform, thereby preventing the rail 6 from deforming too much. This can buffer the rail 6 and reduce the transmission of noise, and prevent the rail 6 from deforming too much due to high temperature expansion at the fixing point.

[0022] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
