Abstract
The utility model pertains to a connecting device between a rail and a sleeper on a railway track, in particular to a height adjustment fastening part in spring stripe III shape with a self-locked function. A height adjustment fastening part in spring stripe III shape with a self-locked function contains a spring stripe and is characterized in that: the utility model consists of a spring strip, a height adjustment matting iron and a pin shaft; the toe terminal of the spring stripe is in the structure of column with a round groove; through a through hole in the center of the height adjustment matting iron, the spring stripe is connected with the height adjustment matting iron by the pin shaft at the toe terminal of the spring stripe. The height adjustment matting iron is in the structure of a cuboid with a square section; the distances between the center axes line of the spring stripe toe terminal and the four faces of the height adjustment matting iron are different, and the height adjustment matting iron is able to rotate around the toe terminal of the spring stripe while the spring stripe is positioned by the pin shaft along axial direction. The utility model aims at solving the problem that in winter, part of the railway track produces a freezing height, which leads to an unevenness of the railway track and that the common spring stripe fastening part in III shape is unable to adjust the fastening pressure and the spring pitch to the rail. The utility model is not only able to suit for the matting boards in different height, but also able to ensure the fastening pressure and the spring pitch to the rail.
Description
One, technical field
The utility model belongs to the linkage of rail and sleeper on the railroad track, particularly relates to a kind of tightening means for height-adjusting that has the spring III type of auto-lock function.
Two, background technology
At present, existing spring III type fastener is that the buckle press that distortion produced of spring is realized repertoire that rail is installed when installing, and in a single day fastener installs and fixes, and spring is to the buckle press of rail and play journey and just be confined in the certain limit, can not regulate.But during actual field is used, when circuit produces freeze injury in the winter time, can not guarantee buckle press and the bullet range request of fastener, influence safety of railway transportation rail.
Three, summary of the invention
1. goal of the invention: the utility model provides a kind of self-locking spring III type tightening means for height-adjusting, its objective is the spring that solves spring III type fastener to the buckle press of rail with play Cheng Buneng and regulate, can not guarantee that fastener is to the buckle press of rail with play the problem that aspect such as range request exists
2. technical scheme: a kind of self-locking spring III type tightening means for height-adjusting, include spring, it is characterized in that: it by spring, heighten parallels, bearing pin is formed, the spring toe-end is the cylindrical-shaped structure that has circular groove, pass the through hole of heightening the parallels center, the toe-end of spring by bearing pin with spring with heighten parallels and couple together.
Heighten the rectangular structure that parallels is the square-section, the central axis of spring toe-end has nothing in common with each other to the distance of four faces heightening parallels, and heightening parallels can rotate in a circumferential direction around the toe-end of spring, and the bearing pin that axially leans on of spring is located.
3. advantage and effect: this self-locking spring III type tightening means for height-adjusting is simple in structure, reasonable in design, has changed in the existing spring III type fastener spring to the rail buckle press with play the nonadjustable defective of journey.Operate easily, make fastener can regulate within the specific limits, guarantee safety of railway transportation the buckle press and the bullet journey of rail.

Five, embodiment
In order to solve above-mentioned goal of the invention, this product has been taked following structure.
Self-locking spring III type tightening means for height-adjusting by spring 1, heighten that parallels 2 and bearing pin 3 form, spring is on the basis of III type spring, change the tabular of its spring 1 toe-end into have axial trough cylindrical-shaped structure, after making that heightening parallels 2 screws in the installation of spring 1 toe-end, the interior retaining of axial trough that utilizes bearing pin 3 to be stuck in spring 1 toe-end is heightened parallels 2, simultaneously, heightening parallels 2 can rotate in a circumferential direction around the spring toe-end.
See Fig. 1～Fig. 3, this self-locking spring III type tightening means for height-adjusting by spring 1, heighten parallels 2 and bearing pin 3 is formed rotatable structure.The toe-end of spring 1 is the cylindrical-shaped structure that head has axial trough in this structure, heighten parallels 2 and be the rectangular structure of square-section, be provided with off-centre (with respect to the square-section axis) cylindrical hole perpendicular to the square-section, the cylindrical hole central axis keeps different distances, a, b with four faces adjusting parallels 2, c, d represents the length of distance respectively, and a＜b＜c＜d is at the pin shaft hole that is provided with the retaining effect perpendicular to the cuboid end of cylindrical hole axis direction.During installation, on the basis that spring 1 installs and fixes, will heighten the toe-end that parallels 2 screws in spring 1, and bearing pin 3 usefulness wooden mallets are knocked in the pin shaft hole of heightening parallels 2, finish the installation of self-locking spring III type tightening means for height-adjusting.
Operation instruction: heighten parallels 2 by rotation, make its circumferential four faces can contact with the flange of rail respectively (wherein heightening parallels 2 downward faces contacts with the flange of rail), make that the toe-end of spring 1 is different with the distance of the flange of rail, realized that the spring toe-end and flange of rail distance is adjustable (promptly apart from being respectively a, b, c, d, 2mm, 4mm, 6mm, 8mm), thereby guaranteed self-locking spring III type tightening means for height-adjusting to the buckle press of rail with play journey and have certain adjustability, and met the requirement of the relevant rule of existing railway.
