Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for high-speed railway platforms, specifically relating to a safety railing for high-speed railway platforms. Background Technology

[0002] High-speed rail platform safety barriers are safety protection devices designed to separate platform personnel from high-speed trains, preventing accidental falls and potential danger. Currently, the safety barriers consist of several bases arranged along the length of the platform. Each base is equipped with a vertically movable lifting assembly, and adjacent lifting assemblies are connected by ropes to form platform screen doors. When the high-speed train comes to a complete stop to allow passengers to board or alight, the lifting assemblies move upwards, causing the ropes to rise, thus removing the barrier separating platform personnel from the train. At other times, the lifting assemblies move downwards, causing the ropes to descend and form the barrier again, ensuring the safety of platform personnel.

[0003] To increase the rope's lifting range, the lifting assembly allows the rope to move up and down relative to the base, while the rope itself can also move up and down relative to the lifting assembly. Currently, the lifting assembly and the base, as well as the sliding rope block and the lifting assembly, use vertical sliding connections via sliders and grooves or shafts and holes. However, these connections have been found to cause significant resistance during lifting due to dust and sand, leading to uneven lifting and lowering. Furthermore, in low-temperature environments, the thermal expansion and contraction of metal can cause the rope to seize up.

[0004] Based on this, this application proposes a safety guardrail for high-speed railway platforms. The lifting component and the base, as well as the sliding rope block on which the rope is installed and the lifting component, are all connected by rollers to achieve rolling cooperation. Compared with the existing sliding cooperation method, this reduces the resistance during the lifting process and improves the smoothness of lifting. Utility Model Content

[0088] A safety railing for a high-speed railway platform, the specific implementation of which is as follows:

[0089] When the high-speed train comes to a complete stop and passengers are allowed to board or alight, the drive mechanism drives the second chain 033 to raise the lifting assembly 01. As the lifting assembly 01 rises, since the first chain 013 is fixed to the connecting column 037, the connecting column 037 pulls down the left side of the first chain 013, thereby causing the right side of the first chain 013 to pull up the lower end of the scissor lift mechanism 2. The scissor lift mechanism 2 retracts, and each sliding rope block moves upward to achieve the synchronous rise of the corresponding rope 02. The safety barrier formed by the rope 02 no longer separates platform personnel from the high-speed train.

[0090] During the remaining time, the drive mechanism drives the second chain 033 to lower the lifting assembly 01. As the lifting assembly 01 lowers, since the first chain 013 is fixed to the connecting column 037, the connecting column 037 pulls up the left side of the first chain 013, thereby pulling down the lower end of the scissor lift mechanism 2. The scissor lift mechanism 2 unfolds, and each sliding rope block moves down to achieve the synchronous descent of the corresponding rope 02. The rope 02 moves down to form a safety barrier to separate platform personnel from the high-speed train and ensure personnel safety.

[0091] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
