Description

Steel rail freezing clamp plate

Technical Field

The utility model relates to a rail freezes splint.

Background

The conventional steel rail clamping plate is as shown in CN 204644804U, and discloses a steel rail insulating clamping plate which comprises a clamping plate body, wherein a groove is formed in one surface of the middle part of the clamping plate body, a convex block is arranged on the other surface of the middle part of the clamping plate body, an insulating layer is arranged on the groove, and the clamping plate body is arranged on the rail web of a steel rail in a mode of combining glue joint and freezing. The utility model discloses a rail insulation clamp plate adopts rail after the insulating cement is consolidated and splint to produce great joint resistance for be difficult to take place relative slip between splint and the rail, simple to operate, insulating nature are good, and detecting instrument can the defect development trend of real-time detection rail, and be a permanent, reliable reinforcement measure.

Although the adhesion between splint and the rail has increased among the above-mentioned technical scheme, it is extremely inconvenient when need demolish splint from the rail when changing the splint.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a rail freezes splint, including the splint body, the working face of splint body and the rail waist groove of rail cooperate, the working face of splint body with be provided with the normal atmospheric temperature solidification adhesive with both fixes between the rail waist groove, the splint body with through a plurality of fasteners looks fixed connection between the rail, there are a plurality of on the splint body set up along its width direction and with fastener matched with through hole, the sled groove has been seted up to at least one tip of the working face of splint body, the length direction that the sled groove was opened along the length direction of splint body extends, the degree of depth direction that opens the sled groove along the thickness direction of splint body extends.

In order to achieve the purpose, the technical scheme of the utility model provides a rail freezes splint, including the splint body, the working face of splint body and the rail waist groove of rail cooperate, the splint body with be provided with the normal atmospheric temperature solidification adhesive of fixing both between the rail waist groove, the splint body with through a plurality of fasteners looks fixed connection between the rail, seted up on the splint body a plurality ofly set up along its width direction and with fastener matched with through hole, the splint body with rail waist groove matched with is connected at least one tip of face and has seted up and open the sled groove, open the length direction in sled groove along the length direction of splint body extends, open the degree of depth direction in sled groove along the thickness direction of splint body extends.

The further improvement is that: both ends of splint body all are provided with open the sled groove.

The further improvement is that: the depth of the prying groove is gradually reduced from the end part of the splint body to the other end part of the splint body.

The further improvement is that: the length of the prying groove is 3 cm-5 cm.

The further improvement is that: the cross section of the prying groove is arc-shaped.

The further improvement is that: one side (namely a working surface) of the clamp plate body matched with the rail web groove is completely attached to the shape of the rail web groove cavity of the steel rail.

The further improvement is that: the fastener is a high strength bolt.

The utility model has the advantages and the beneficial effects that: open the sled groove through seting up on the splint body, when demolising splint, demolish the fastener earlier, then make full use of glues the peel strength of adhesive linkage and far than its small characteristics of shear strength, insert through the instrument and open the sled inslot, the wedging power makes the sticky layer between splint and the rail peel off to make splint and rail take off, laborsaving and improved the efficiency of demolising of splint.

Drawings

Fig. 1 is a schematic view of the present invention.

Wherein: 1. a splint body; 2. a through hole; 3. a steel rail; 4. and (4) opening the prying groove.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, a rail freezes splint, including splint body 1, the working face of splint body 1 cooperatees with the rail waist groove of rail 3, the working face of splint body 1 with be provided with the normal atmospheric temperature curing adhesive of fixing both between the rail waist groove, splint body 1 with through a plurality of fasteners looks fixed connection between the rail 3, splint body 1 is last have a plurality of its width direction of edge set up and with fastener matched with through hole 2, the fastener adopts the high strength bolt, prying groove 4 has all been seted up at the both ends of the working face of splint body, prying groove 4's length direction along splint body 1's length direction extends, prying groove 4's degree of depth direction along splint body 1's thickness direction extends.

In order to facilitate the insertion of a dismantling tool into the prying groove 4 and facilitate the smooth force application of dismantling personnel when the splint is pried, the depth of the prying groove 4 is gradually reduced from the end part of the splint body 1 to the other end part of the splint body 1.

In order to ensure that the sufficient stress surface is formed between the dismantling tool and the clamping plate and that the opening of the prying groove 4 does not affect the contact surface between the clamping plate and the steel rail 3, the size of the prying groove 4 needs to be limited, and therefore in the embodiment, the length of the prying groove 4 is 3 cm-5 cm.

In order to ensure that the clamping plate cannot be damaged in the prying process, the cross section of the prying groove 4 is arc-shaped.

In the preferred embodiment of the present invention, the working surface of the clamp plate body 1 matched with the rail web groove completely fits the shape of the rail web groove cavity.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
