Embodiment Construction

[0028] In order to make those skilled in the art understand the present invention better, the present invention will be further described below in conjunction with specific embodiment:

[0029] like Figure 1 to Figure 2 As shown, a gauge limiter for an overhead unit of a railway line includes a base panel 1, the two ends of the base panel 1 are respectively fixed with stoppers 4 for limiting the longitudinal displacement, and between the two stoppers 4 is fixed a stopper for limiting the lateral displacement. Displacement clip 2.

[0030] The base panel 1 is strip-shaped, and the stopper 4 is also strip-shaped, and the length direction of the stopper 4 is consistent with the length direction of the base panel 1, and the width of the stopper 4 is less than the width of the base panel 1. 4 Set on one side of the two ends of the base panel 1, fix the base panel on the overhead beam, clamp the overhead beam, and then set the stopper on one side of the base panel, so that the end...

Abstract

The invention discloses a gauge limiter of a rail track overhead unit. The gauge limiter comprises a base face plate. Stop pieces for limiting the longitudinal displacement are fixedly arranged at thetwo ends of the base face plate respectively. A clamping pin for limiting the transverse displacement is fixedly arranged between the two stop pieces. The gauge limiter is mainly installed on an overhead beam at one end of a railway sleeper; according to the limiter, the stop pieces and the clamping pin are arranged on the base face plate, when the limiter is used, the base face plate is fixed tothe overhead beam, the clamping pin can clamp the overhead beam, and the railway overhead beam can be effectively limited in the transverse displacement direction; in addition, the stop pieces make contact with sleeper ends on the two sides of the overhead beam, the sleeper ends abut against the stop pieces, and the longitudinal displacement of the transverse beam can be effectively limited. Thus, the gauge limiter is not prone to disengagement, the transverse and longitudinal displacement on a rail track can be effectively reduced, the track gauge deviation is reduced, and the train passingsafety and smoothness are ensured.

Description

technical field [0001] The invention relates to the technical field of equipment related to railway lines, in particular to a gauge limiter for overhead units of railway lines. Background technique [0002] Underpass railway jacking culvert often plays an important role in railway hub cities, and is an important construction method for road crossing railway lines. For the complex construction environment around the city, limited by various external conditions, the requirements for overhead equipment used to cross existing railway lines are also increasing. With the continuous increase of the span of the box bridge and the decrease of the bevel angle with the railway, it is very Standard overhead designs continue to appear, and the use of existing overhead equipment can no longer meet construction needs. [0003] As an important part of the box bridge jacking construction, the overhead line works directly on the line, which has the greatest impact on the existing railway equ...
