AI Technical Summary
When installing the curved section track, the curved section track is inclined due to the inclination of the load-bearing surface of the rail sleeper, which increases the risk of overall tilting. The existing anti-falling device is not convenient for slip treatment, affecting the working efficiency.
An anti-reflection device is designed, including a frame and a first mating assembly, which is fixed to the sleeper, and the first mating assembly abuts against the side walls of the inner side of the track and can roll with respect to the track, thereby driving the anti-reflection device to move along the track.
This device can effectively prevent the curved segment track from tipping toward the inside, and improve the working efficiency of the anti-falling device in the preset position of the curved segment track through the slip function.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of railway maintenance engineering, and in particular to an anti-fall device. Background Art
[0002] When replacing a longer track in a curved section of a track line, the curved section track needs to be set higher on the outside and lower on the inside, so the bearing surface of the sleeper will tilt inward. When the curved section track is installed on the bearing surface of the sleeper, it will inevitably tilt inward of the curve. Since the curved section track always maintains a tendency to tilt inward, the degree of inclination of the curved section track will increase when the curved section track is stretched, resulting in the risk of the curved section track topping as a whole. If the curved section track topples over, it will cause large-scale rework and difficult recovery, affecting the normal operation of the track line.

[0039] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.
[0040] Please also read Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides an anti-fall device 1, comprising a frame 11 and a first mating component 12. The frame 11 can be fixed to a sleeper for carrying a track. The first mating component 12 is arranged on the frame 11, and the first mating component 12 is used to abut against the side wall inside the track and can roll relative to the track to drive the anti-fall device 1 to move along the track.
[0041] It should be noted that the track in the following embodiments refers to a curved track, and the inner side of the track refers to the concave side of the curved track, that is, the side where the center of the curve of the curved track is located.
[0042] In this embodiment, when the anti-fall device 1 is in a fixed state, the frame 11 is fixed to the sleeper, and the first mating component 12 abuts against the inner side wall of the track, thereby applying a force toward the outer side of the track to the inner side wall of the track, thereby preventing the track from falling inward.
[0043] When the anti-overturn device 1 is in a floating state, the frame 11 is not fixed to the sleeper, and the first mating component 12 can roll on the side wall inside the track along the extension direction of the track, so that the anti-overturn device 1 can move along the track, making it convenient for the staff to roll the anti-overturn device 1 along the track to a preset position of the curved section track.
[0044] The frame 11 may include two spaced plates 111, and the first matching assembly 12 is disposed between the two plates 111. When the anti-fall device 1 is in a fixed state, the spacing direction of the two plates 111 is the same as the extension direction of the track.
