Description

Technical Field

[0001] This utility model relates to the field of rail clamp technology, and in particular to a non-circular joint clamp. Background Technology

[0002] Railway track safety is of paramount importance in transportation construction. During track design and rail laying, it is necessary to sequentially connect two consecutive rail sections to form a unified track. Rail clamps (rail joint clamps, also known as fishplates or track clamps) are fasteners used to connect rails, serving a connecting function at the rail joint. For two consecutive rail sections with the same height, ordinary rail clamps are sufficient. However, for rail sections with different heights, irregularly shaped clamps are required. Irregularly shaped clamps are mainly used to connect rails with the same height but different bases.

[0003] Currently, the irregular-shaped rail clamps are designed to match the sides of the two rail sections. However, during use, due to the different foundation depths and ballast laying conditions of the two rail sections on the track bed, the stress on the two rail sections is also different when the train passes over them. This can cause the two rails to misalign. Over time, the irregular-shaped rail clamps will deform and may even break at the rail joints, resulting in reduced stability and a shorter service life. Therefore, there is an urgent need for an irregular-shaped rail clamp that can ensure the stability of the rail joints. Utility Model Content

[0004] The purpose of this utility model is to provide a non-circular joint clamp to solve the problems of existing non-circular joint clamps deforming, even breaking at the joint of the rail, resulting in reduced stability and service life.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A non-circular joint clamp includes a non-circular clamp, a retainer is provided at the bottom of the non-circular clamp along its direction, the retainer is adapted to the bottom of the rail, and a locking hole is provided at the waist of the non-circular clamp, the locking hole is adapted to the web of the rail.

[0007] A further technical solution is that the width of the turning point of the card is less than the joint width of the two rails.

[0008] A further technical solution is that the irregularly shaped clamp is provided with at least one arc-shaped part, which is close to the joint of the rail.

[0009] A further technical solution is that the arc-shaped part is located between two adjacent keyholes.

[0010] A further technical solution is that the card holder is provided with a trapezoidal groove that is adapted to the bottom of the rail.

[0011] A further technical solution is that the minimum diameter of the trapezoidal groove is smaller than the minimum diameter of the rail bottom.

[0012] A further technical solution is that the top of the irregularly shaped clamp is provided with a top support, which is adapted to the top of the rail.

[0013] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0014] This utility model proposes an irregular joint clamp plate, which can be used to connect two rails with different front and rear sections. Moreover, by using a clip, the bottom of the rails at different positions of the two rails can be lifted and fixed. When the rails are under stress, it prevents misalignment at the joint, which could lead to deformation of the irregular clamp plate or even breakage at the rail joint over time. This ensures the stability of the clamp plate and improves its service life. Attached Figure Description

[0025] Example 1:

[0026] This implementation example Figure 1 and Figure 2 As shown, a non-circular joint clamp includes a non-circular clamp 1. A clip 3 is provided at the bottom of the non-circular clamp 1 along its direction. The clip 3 is adapted to the rail bottom 21 of the rail 2. A locking hole 4 is provided on the waist of the non-circular clamp 1. The locking hole 4 is adapted to the rail waist 22 of the rail 2.

[0027] During installation, first install the two irregularly shaped clamps 1 on both sides of the joint of the two rail sections 2, ensuring that the clamping brackets 3 of the irregularly shaped clamps 1 are locked to the rail base 21 of the rail 2. Then, install the rail bolts, which pass through the two irregularly shaped clamps 1 and the rail 2, and lock the three together firmly. The irregularly shaped clamps 1 can be used to connect two rail sections 2 that are not identical. Moreover, the clamping brackets 3 can support and fix the rail base 21 at different positions of the two rail sections 2. When the rail 2 is under stress, it prevents the joint from becoming misaligned, which could lead to deformation of the irregularly shaped clamps over time, or even breakage at the rail joint. This ensures the stability of the clamps and extends their service life.

[0028] Preferably, the width of the turning point of the cassette 3 is less than the joint width of the two rails 2.

[0029] Rail 2 will expand and contract with temperature changes, to prevent the rail from being affected by the turning point of the clamp 3 (i.e. the point where the clamp 3 changes height) when it expands and contracts with temperature changes.

[0030] Example 2:

[0031] The irregularly shaped clamp 1 is provided with at least one arc-shaped part 5, which is close to the joint of the rail 2.

[0032] When the rail 2 expands and contracts due to heat, the arc-shaped part 5 will expand and contract accordingly to adapt to the changes in the rail.

[0033] Preferably, the arc-shaped portion 5 is located between two adjacent keyholes 4.

[0034] The keyhole 4 avoids the arc-shaped part 5 to prevent interference with the effect of the arc-shaped part 5.

[0035] Preferably, the tray 3 is provided with a trapezoidal groove that matches the rail base 21. The minimum diameter of the trapezoidal groove is smaller than the minimum diameter of the rail base 21.

[0036] The trapezoidal groove of the clip 3 engages tightly with the rail base 21, ensuring a secure fixation of the rail 2.

[0037] Preferably, the top of the irregularly shaped clamp 1 is provided with a top support 6, which is adapted to the rail top 23 of the rail 2.

[0038] The top support 6 of the irregularly shaped clamp 1 is used to support the rail top 23 of the rail 2, thus providing support for the load.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
