Description

TECHNICAL FIELD

[0001] The present application relates to a gauge adjusting piece. BACKGROUND

[0002] The track gauge is generally adjusted by the gauge block on the fastener, and the gauge cannot be adjusted by the fastener in the turnout track and the sliding bed. The gauge adjusting piece is inserted into the gap between the sliding bed plate and the rail bottom to adjust the gauge. In order to prevent the gauge adjusting piece from loosening and falling off due to rail vibration after installation, thereby changing the gauge, a limiting device is generally provided on the gauge adjusting piece to limit its movement along the length direction of the rail. The traditional method is to bend both ends of the gauge adjusting piece, but one end is bent in advance during installation, and the other end is bent after installation. One end is not convenient to bend, and the other end is easy to be forgotten to bend due to the negligence of the operator, thereby causing the adjusting piece to loosen and fall off due to vibration during use. The patent 201220753204.9 discloses a gauge adjusting piece, and the lugs at both ends are used for limiting. The lugs are flush with the pad during installation, and the lugs need to be folded to achieve limiting after installation. However, it is still impossible to avoid the lugs not being folded due to negligence. SUMMARY

[0003] In order to solve the problems in the prior art, the present application provides a gauge adjusting piece which can automatically achieve limiting. The technical scheme adopted by the present application is as follows:

[0004] A gauge adjusting piece, comprising a gauge adjusting portion, a limiting portion provided at one end of the gauge adjusting portion, and an elastic stop portion provided at the other end of the gauge adjusting portion away from the limiting portion, wherein the elastic stop portion can be deformed under pressure and can restore the original shape after releasing the pressure.

[0005] Further, the elastic stop portion is a folded edge formed by cutting a tongue inside the gauge adjusting portion, and the folded edge is inclined toward the limiting portion.

[0006] Further, the elastic stop portion is a folded edge formed by cutting a tongue at the edge of the gauge adjusting portion, and the folded edge is inclined toward the limiting portion.

[0007] Further, the angle between the folded edge and the gauge adjusting portion is 20°-80°.

[0008] Further, the angle between the folded edge and the gauge adjusting portion is 45°.

[0009] Further, the elastic stop portion is an arc-shaped protrusion formed by bending along the width of the gauge adjusting portion.

[0010] Further, the gauge adjusting piece is made of spring steel.

[0011] According to the technical scheme, the limiting part can be processed in advance, the elastic stop part can be deformed when being inserted between the slide bed and the rail, and the elastic stop part can restore the original shape to realize the limiting function after being completely inserted. The process does not need manual processing of the stop part, and the limiting function can be automatically realized. BRIEF DESCRIPTION OF DRAWINGS

[0017] The present application designs a gauge adjusting piece, which comprises a gauge adjusting part 1. After being installed into a rail, the gauge adjusting part 1 mainly plays a role of adjusting the gauge, that is, the part between the slide bed and the rail for adjusting the gauge. The design point is that at least one elastic stop part 2 is arranged at one end of the gauge adjusting part 1. The elastic stop part 2 can be deformed due to external pressure, so that the height or shape of the elastic stop part 2 is changed, thereby enabling the gauge adjusting piece to be smoothly inserted into the gap between the rail A and the slide bed B. When being completely inserted, the external pressure disappears, and the elastic stop part 2 can restore the original shape, thereby being stopped at the edge of the slide bed to realize the limiting function. Figure 5

[0018] In order to facilitate use, the elastic stop part 2 can be arranged at both ends of the gauge adjusting part 1. In this way, both ends of the gauge adjusting piece can be inserted, which is convenient to operate. Of course, the elastic stop part 2 can be arranged at one end, and the traditional limiting part 3 can be arranged at the other end, that is, the limiting part formed by bending the end of the gauge adjusting part into a flange, or other forms of limiting part 3, such as a welded stop block, a press screw, etc. Of course, in order to facilitate processing and good integrity, the limiting part 3 is preferably in the form of a flange. As can be seen from the following embodiments, the limiting part 3, the elastic stop part 2 and the gauge adjusting part 1 are an integral plate, which can be realized by simple machining.

[0019] The specific implementation mode of the elastic stop part 2 is provided with the following three embodiments: ​

[0020] Embodiment 1

[0021] The elastic stopper 2 is formed by a tongue cutting process on one end of the gauge adjusting part 1 to form a flange inside, which should be inclined towards the far end of the gauge adjusting part 1, i.e. the flange opening position reference Figure 1 should be towards the side of the limiting part 3, so that it can deform smoothly when inserted into the gap between the rail and the sliding bed without being blocked by the sliding bed.

[0022] Embodiment 2

[0023] In embodiment 1, the connection between the flange and the gauge adjusting part 1 is close to the end of the gauge adjusting part 1, and after maximum deformation, the flange can be flush with the gauge adjusting part, smoothly passing through the gap. Of course, based on embodiment 1, the form of embodiment 2 can also be used, the connection between the flange and the gauge adjusting part 1 is set on the side away from the end of the gauge adjusting part 1, this form at least needs to ensure that the gap between the rail and the sliding bed is greater than 2 times the thickness of the gauge adjusting part during installation, and of course, during the installation of the gauge adjusting piece, the rail needs to be moved a small distance away from the sliding bed to facilitate the insertion of the gauge adjusting piece, so it can also be used.

[0024] Embodiment 3

[0025] The same tongue cutting process as in embodiment 1 can be used to make a flange on the edge of the gauge adjusting part 1, which can also be limited.

[0026] The above several embodiments are basically simple structural deformation processing based on the embodiment, similar ones will not be listed one by one, such as in embodiment 3, a flange can be set on one side edge, or flanges can be set on both side edges, etc. Deformation forms belong to the content claimed by the present application.

[0027] In the above three embodiments, the included angle between the flange and the gauge adjusting part 1 is generally set between 20° and 80°, the angle is too small and the limiting effect is not obvious, and the angle is too large and it is difficult to insert, therefore 45° is the best choice.

[0028] Embodiment 4

[0029] As shown in Figure 4 The elastic stopper 2 is an arc-shaped protrusion formed by bending along the width of the gauge adjusting part 1, which is made into an arc shape to make it more smooth during deformation.

[0030] The above structure will deform to some extent during installation due to the elastic stopper 2, and after deformation, it can return to its original state, therefore the gauge adjusting part 1 is made of spring steel material to adapt to the deformation and recovery of the elastic stopper 2.

[0031] This adjustment piece is only used for adjustment between the sliding bed plate and the steel rail.
