Description

Technical Field

[0001] This utility model relates to the field of track technology, and more specifically, to a novel rail clamp. Background Technology

[0002] Early designs primarily used exothermic welding to attach cables to the rail web, naturally creating weld beads. Improper exothermic welding can easily produce brittle martensite on the rail surface. Martensite is hard and brittle, making it highly susceptible to cracking and ultimately causing brittle rail fracture. According to the emergency handling procedure for rail fractures: when the rail break reaches 30mm, immediate emergency treatment should be initiated. Apply a splint or bulge splint to the break and secure it with a first-aid device.

[0003] The protruding weld beads and insufficient internal space of ordinary clamps prevent the ordinary clamps from fitting snugly against the lower edge of the rail head, the rail web, and the upper edge of the rail base. The currently used emergency rescue devices and ordinary clamps cannot effectively cover the rail weld bead conductor area. When the weld bead conductor area is damaged, the lack of suitable clamps prevents the use of emergency rescue devices for temporary reinforcement, thus rendering the emergency rescue devices ineffective. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a new type of rail clamp that can solve the above problems.

[0005] A novel rail clamp includes a clamp body with a groove for accommodating rail weld beads. The inner side of the clamp body is in contact with the web of the rail, the top surface of the clamp body is in contact with the lower edge of the rail head, the bottom surface of the clamp body is in contact with the upper edge of the rail bottom, and the two ends of the groove extend through the clamp body.

[0006] Furthermore, the outer surface of the clamp body is a planar structure.

[0007] Furthermore, the cross-section of the groove is a trapezoidal structure, the inner upper side and the inner lower side of the groove are both inclined, and the width of the groove opening is greater than the width of the inner bottom surface.

[0008] Furthermore, the connection points between the inner upper side and the inner lower side and the inner bottom surface are all arc-shaped structures.

[0009] Furthermore, a recess is provided at the intersection of the top surface and the outer surface of the clamp body.

[0010] Furthermore, the outer surface of the clamp body is provided with reinforcing ribs.

[0011] Furthermore, the side of the reinforcing rib away from the clamping plate body is arc-shaped, and the top surface of the reinforcing rib is provided with a recess near the clamping plate body.

[0012] Furthermore, the thickness of the reinforcing rib is the same as the depth of the groove.

[0013] Furthermore, the length of the reinforcing rib is the same as the length of the clamping plate body.

[0014] Furthermore, the surface of the clamp body is provided with a coating that increases the coefficient of friction.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This novel rail clamp features a groove on its body to accommodate rail weld beads. The groove extends through the entire clamp body, allowing for the storage of multiple weld beads with no limitation on the distance between them. The length of the clamp body can also be adjusted according to actual needs. The inner surface of the clamp body fits against the rail web, the top surface fits against the lower edge of the rail head, and the bottom surface fits against the upper edge of the rail base. During the repair of damaged rails, the clamping force provided by the clamps and bolts creates a clear positive pressure on the rail jaws and the rail base slope. This positive pressure increases with the clamping force provided by the clamps and bolts, generating the necessary static friction force on the stress surface, thus providing emergency fixation for broken rails.

[0017] The clamp body adopts an inner concave and outer flat structure. The outer flatness provides sufficient space for clamp installation, while the inner concave variable cross-section is designed with a smooth arc connection to avoid stress concentration. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Statistical analysis of the conductor weld beads 11 of a certain line shows that the weld beads 11 are all located 80 to 90 mm from the middle of the rail web 12. The maximum difference between two weld beads 11 is 320 mm and the minimum difference is 98 mm. The height of both weld beads 11 is less than 23 mm.

[0029] like Figures 1-4 As shown, the novel rail clamp in this embodiment includes a clamp body 2 with a groove 21 for accommodating the weld bead 11 of the rail 1. The inner side 22 of the clamp body 2 is fitted with the web 12 of the rail 1, the top surface 23 of the clamp body 2 is fitted with the lower edge of the rail head 13 of the rail 1, the bottom surface 24 of the clamp body 2 is fitted with the upper edge of the rail bottom 14 of the rail 1, and the outer side 25 of the clamp body 2 is a planar structure. The two ends of the groove 21 penetrate the clamp body 2, and the cross-section of the groove 21 is a trapezoidal structure. The inner upper side 201 and inner lower side 202 of the groove 21 are both inclined, and the width of the groove opening 203 is greater than the width of the inner bottom surface 204. The connection between the inner upper side 201 and the inner lower side 202 and the inner bottom surface 204 is an arc-shaped structure.

[0030] The clamp body 2 is a non-perforated structure, and is fixed to both sides of the rail 1 by clamps and bolts. A groove 21 is provided on the clamp body 2 to accommodate weld beads 11 of the rail 1. The two ends of the groove 21 extend through the clamp body 2, thus accommodating multiple weld beads 11, with no limitation on the distance between them. The length of the clamp body 2 can also be cut according to actual needs. The inner surface 22 of the clamp body 2 is in contact with the rail web 12 of the rail 1, the top surface 23 is in contact with the lower edge of the rail head 13, and the bottom surface 24 is in contact with the upper edge of the rail base 14. During the repair of the damaged rail 1, the clamping force provided by the clamps and bolts creates a clear positive pressure on the lower jaw of the rail 1 and the slope of the rail base 14. This positive pressure increases with the clamping force provided by the clamps and bolts, generating the required static friction force on the stress surface, thereby providing emergency fixation for the broken rail 1. The clamp body 2 adopts an inner concave and outer flat structure. The outer flat structure provides sufficient space for clamp installation, while the inner concave variable cross-section is designed with a smooth arc connection to avoid stress concentration.

[0031] In this embodiment, a recess 26 is provided at the intersection of the top surface 23 and the outer surface 25 of the clamp body 2. The recess 26 prevents the clamp body 2 from protruding horizontally from the side of the rail head 13. The surface of the clamp body 2 is coated with a coating that increases the coefficient of friction. This coating roughens the surface of the clamp, thereby increasing friction and effectively improving the overall integrity of the rail 1 after temporary reinforcement. Specifically, the coating that increases the coefficient of friction can be selected from polyurethane coatings, rubber coatings, polymer coatings, fluorinated coatings, nano-coatings, cellulose coatings, etc.

[0032] Specifically, in this embodiment, the width of the groove 203 of the groove 21 is 64mm, the width of the inner bottom surface 204 of the groove 21 is 53mm, the depth of the groove 21 is 24mm, the distance between the inner bottom surface 204 of the groove 21 and the outer side surface 25 of the clamping plate body 2 is 20.5mm, and the distance between the uppermost end of the clamping plate body 2 and the top of the groove 203 of the groove 21 is 20mm.

[0033] Example 2:

[0034] In this embodiment, the novel rail clamp, based on the concave-outer-flat technical solution, further improves the clamp body 2 by reinforcing weak points. Specifically, as follows... Figure 5 and Figure 6 As shown, the outer side 25 of the clamping plate body 2 is provided with a reinforcing rib 3. The side of the reinforcing rib 3 away from the clamping plate body 2 is arc-shaped. The top surface 23 of the reinforcing rib 3 is provided with a recess 31 for clamping by the clamping device near the clamping plate body 2. The thickness of the reinforcing rib 3 is the same as the depth of the recess 21, and the length of the reinforcing rib 3 is the same as the length of the clamping plate body 2.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
