Description
Technical Field
[0001] The utility model relates to the technical field of evacuation platforms, in particular to a subway evacuation platform. Background Art
[0002] An evacuation platform is a dedicated passageway within a subway tunnel used to evacuate passengers. The platform's height is generally the same as the station platform. In the event of an accident, the train doors can be immediately opened to evacuate passengers from the platform to the nearest station. During subway operations, if an accident occurs in a tunnel, after the train stops, passengers can exit the platform through the train doors, quickly leaving the scene and safely reaching the nearest station or exit, thus ensuring passenger safety. If an accident occurs on the platform, passengers can exit the platform through the evacuation door in the train cab and quickly leave.
[0003] The existing subway evacuation platform is narrow and has no baffles, which can easily cause people on the platform to fall off the platform due to congestion, which easily brings safety hazards. In response to this, we propose a subway evacuation platform. Utility Model Content

[0013] Preferably, the upper end surface of the boss is flush with the upper end surface of the foot pedal.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. This type of subway evacuation platform, by setting a guardrail on the foot pedal of the evacuation platform, enables the cylinder to work, and the U-shaped swing arm to swing a certain angle, which can cause the rotating shaft to rotate a certain angle, thereby driving the plug-in rod to swing. Since the plug-in rod and the guardrail are fixedly installed, the guardrail produces the same movement during the movement of the plug-in rod and can swing to a vertical state; in this state, the side of the evacuation platform can be blocked to prevent people on the platform from falling off the platform due to congestion, thereby ensuring the safety of the evacuation platform.
[0016] 2. The setting of guardrails on this type of subway evacuation platform not only increases the protection performance of the evacuation platform, but also increases the anti-slip effect of the upper end surface of the footrest. During use, it increases friction, thereby further improving the safety of the evacuation platform;
[0017] 3. This type of subway evacuation platform only needs to be equipped with cylinders inside the supporting members at both ends of the evacuation platform. No need to set up multiple cylinders, and they can be driven simultaneously, which reduces the cost of using the evacuation platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example: See Figure 1-6 The present invention provides a technical solution: a subway evacuation platform, which is mainly aimed at improving the existing subway evacuation platform. Since the platform is narrow and has no baffles, it is easy for people on the platform to fall off the platform due to crowding, which easily leads to safety hazards. The specific solution is as follows: It includes a pier 1, a support 2 and a pedal assembly 3, wherein the pier 1 is fixed to the side wall of the tunnel by expansion screws, and the end of the pier 1 that fits the tunnel is provided with an arc, which can make it easier to fit and play a stable support effect. Figure 1 As shown, the pier 1 is approximately a triangular structure, which can play a role of stable support.
[0027] Furthermore, the longitudinal section of the support member 2 is V-shaped, and the support member 2 is arranged to fit the inclined surface of the pier 1. The pedal assembly 3 is overlapped on the upper middle portion of the support member 2, and the support member 2 is arranged on the inclined surface of the pier 1. A boss 4 is provided in the middle portion of the support member 2, and a drive assembly 5 is provided on the side of the boss 4 away from the pier 1.
[0028] See also Figure 2 、 Figure 4 and Figure 5The drive assembly 5 includes a rotating shaft 52, with spline grooves 55 formed on the outer end surfaces of adjacent rotating shafts 52. The rotating shafts 52 are rotatably connected to the boss 4 through bearings. A U-shaped rocker 53 is provided between adjacent rotating shafts 52. The U-shaped rocker 53 is U-shaped and is located between adjacent rotating shafts 52. A concave groove 51 is formed below the boss 4, and a cylinder 54 is installed inside the concave groove 51. The output shaft of the cylinder 54 is hinged to the U-shaped rocker 53 via a pin.
[0029] It is worth noting that the number of cylinders 54 does not need to be determined by the number of concave grooves 51. They can be installed inside the support members 2 at both ends of the evacuation platform. Without the need for multiple cylinders, they can all be driven simultaneously, reducing the cost of using the evacuation platform. When the cylinders 54 are working, the U-shaped rocker 53 swings a certain angle, which can cause the rotating shaft 52 to rotate a certain angle.
[0030] See also Figure 2 and Figure 6 Among them, the pedal assembly 3 includes a foot pedal 30, which is provided with a groove 31, and a guardrail rod 32 is provided inside the groove 31. The opening of the groove 31 can not only increase the anti-slip effect of the upper end surface of the foot pedal 30, but also facilitate the placement of the guardrail rod 32.
[0031] Specifically, the guardrail rod 32 is rotatably connected to the footrest 30 and is located on the side of the support member 2 away from the pier 1. Connecting rods 33 are provided on both sides of the guardrail rod 32. Splined ends 34 are provided at the outer ends of adjacent connecting rods 33, and the splined ends 34 are movably inserted into corresponding splined grooves 55. The centers of the splined grooves 55 and the splined ends 34 are collinear, and the depth of the splined grooves 55 is less than the length of the splined ends 34. The boss 4 is located between adjacent footrests 30, with a spacing of less than 1 cm between the boss 4 and the footrest 30. The upper end surface of the boss 4 is flush with the upper end surface of the footrest 30. During installation, the splined ends 34 on the connecting rod 33 snap into the splined grooves 55 on the boss 4, allowing the connecting rod 33 and the rotating shaft 52 to rotate simultaneously without relative rotation. This plug-in connection method is convenient and easier to install.
[0032] Working principle: When using this kind of subway evacuation platform, multiple piers 1 are arranged at intervals inside the subway tunnel, and the piers 1 are fixed by expansion bolts; since the spacing between adjacent piers 1 is greater than the width of the foot pedal 30, it is convenient to place the pedal assembly 3; when placing the pedal assembly 3, the spline end 34 on the connecting rod 33 is inserted into the spline groove 55 on the boss 4, so that the connecting rod 33 and the rotating shaft 52 can rotate simultaneously without relative rotation; when the cylinder 54 is working, the U-shaped rocker 53 swings a certain angle, which can make the rotating shaft 52 rotate a certain angle, thereby driving the connecting rod 33 to swing, and since the connecting rod 33 and the guardrail rod 32 are fixedly installed, during the movement of the connecting rod 33, the guardrail rod 32 produces the same movement and can swing to a vertical state, such as Figure 1 As shown, in this state, the side of the evacuation platform can be blocked to prevent people on the platform from falling off the platform due to congestion, thereby further ensuring the safety of the evacuation platform.
[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
