Problems solved by technology

The guard rail will be worn after the repeated action of the wheel, which will cause the size of the "guard rail rim groove" to become larger. If the limit value is exceeded, the guard rail will lose its protective effect and seriously affect driving safety. Therefore, it must be installed between the guard rail and the guard rail The size of the flange groove of the guard rail is controlled by increasing or decreasing the adjustment piece between the plates to meet the requirements of the maintenance standard
[0003] At present, there are mainly two types of adjustment plates on the market: straight groove type and round hole type. The straight groove type can be directly clamped on the bolts connecting the guard rail and the guard rail support plate. It is easy to install, but it is easy to cause damage due to vibration or bolt corrosion. The adjustment piece is loose and falls off; the round hole adjustment piece is installed stably, but the guard rail and the guard rail support plate need to be completely detached during the installation process, which is labor-intensive and difficult to operate

[0030] Please refer to figure 1 As shown, the present embodiment provides a self-locking railway turnout adjusting piece 100, which is applied to the guard rail assembly of the railway turnout to adjust the distance between the guard rail and the guard rail support, namely Adjust the size of the Guard Rail Flange Groove. The self-locking railway switch adjustment plate 100 provided in this embodiment can be quickly installed and has a self-locking function.

[0031] The self-locking railway switch adjustment plate 100 provided in this embodiment includes a plate body 110, a first elastic plate 130 and a second elastic plate 150, and the outer edge of the plate body 110 is provided with a gap 111 for clamping bolts. According to actual application conditions, the gap An expansion opening can be added at the opening position of 111 to facilitate the insertion of bolts. The opposite sides of the notch 111 are respectively provided with a first notch wall 1111 and a second notch...

Abstract

The invention discloses a self-locking railway turnout adjusting sheet and a track protection assembly, and relates to the technical field of railways. The self-locking railway turnout adjusting sheetcomprises a sheet body and a first elastic piece, a notch used for clamping a bolt is formed in the outer edge of the piece body, a first mounting groove is formed in a first notch wall of the notch,a second side wall of the first mounting groove is closer to the opening position of the notch than a first side wall, and a first connecting end of the first elastic piece is connected with the bottom wall of the first mounting groove, a first movable end of the first elastic piece extends into the notch, gaps exist between the first elastic piece and the first side wall and between the first elastic piece and the second side wall, and when a first movable end rotates to make contact with the first side wall, the distance between the first movable end and a second notch wall of the notch islarger than that between the first movable end and the second notch wall when the first movable end rotates to make contact with the second side wall, and when the first movable end is in contact withthe second side wall, the first movable end is kept extending into the notch. The self-locking railway turnout adjusting sheet can be quickly installed and has a self-locking function.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a self-locking railway switch adjustment piece and a guard rail assembly. Background technique [0002] In order to prevent derailment accidents caused by the train hitting the tip of the frog center and climbing up the rail surface or entering the opposite direction when the train passes the turnout from one track to the other, the turnout is equipped with a guard rail assembly. The "guard rail rim groove" formed between the guard rail and the guide rail set by the guard rail assembly can limit the position of the wheel on one side of the wheel pair from being too biased towards the center of the track, so as to prevent the wheels on the other side of the wheel pair from hitting the frog center cutting edge purpose. The guard rail will be worn after the repeated action of the wheel, which will cause the size of the "guard rail rim groove" to become larger. If the limit value i...
