Description

In the present invention, in the platform where the distance between the subway train and the landing is widened, by quickly satisfying the widened distance between the train and the landing by the openable safety platform installed in the platform (subway platform). The present invention relates to a safety scaffolding for a subway platform that can prevent a safety accident in which passengers entering and leaving the train lose their feet. Specifically, the scaffold plate is fixed by using a hinge part at the front end part of the drive guide arm installed on the frame that is installed buried inside the edge of the landing with the drive motor and drive gear interposed. It is installed so that it can rotate left and right at an angle, and at this time, guide arms are installed at the center of both sides of the frame, respectively, and can be rotated with a support base installed at both rear ends of the scaffolding plate. In the case of a platform in which the distance between the subway train and the platform edge is widened by installing other guide arms on both sides of the front and rotating to both sides of the scaffold plate, the inside of the platform edge The opening and closing safety scaffolding installed in the can meet the distance between the train and the landing, and this prevents the safety accident that the passenger's feet get into the widened gap Of course, in the event of a collision due to entry or departure of a train with the safety scaffold protruding due to a malfunction of the safety scaffold operation, the safety is stopped while the driving force is stopped by the torque clutch of the drive guide arm that opens and closes the safety scaffold. The present invention relates to a safety scaffold for a subway platform that can be easily manufactured and installed by a simple opening / closing structure of a safety scaffold, preventing a safety accident caused by a collision of the safety scaffold by returning the scaffold quickly.

In general, the distance between the edge of the subway train and the landing is formed wide, so that the passenger's foot can easily escape through the gap between the train and the edge of the landing. In particular, there is a disadvantage that such safety accidents frequently occur in the case of a child or an elderly person who is inferior in risk coping capability.

Accordingly, in order to improve the disadvantage that passengers can easily slip into the gap between the train and the landing edge as described above, conventionally, as illustrated in FIG. A fixed rubber column 2 is installed in the section 1 so that the passenger's foot cannot be pulled out in the gap between the train and the landing edge.

However, in order to prevent collision with the train, the rubber support 2 as described above forms a certain distance between the train and the landing edge, and particularly in the case of a curved landing, There is a problem that the distance between trains is widely formed.

On the other hand, recently, in order to improve the disadvantages and problems as described above, when a train enters the subway platform, the air compressor and the scaffolding connected to the air cylinder are moved forward and backward in a sliding manner. Te, safety scaffold to disappear spacing between subway Stop the edge and the train are known in Korean Patent registration No. 10-0318334.

Installed to move back and forth.

Therefore, when the train enters the subway platform, the operation of the air compressor 30 embedded behind the platform causes the air cylinder 40 connected by the air hose 20 to operate, and the connection terminal 41 at one end of the air cylinder 40 advances. Since the scaffold 60 integrally connected to the connection terminal 41 rides on the rails 50 on both sides, the distance between the edge 10 of the subway platform and the train is eliminated.

However, the safety platform of the subway platform as described above is formed of a curve because the moving distance of the scaffold 60 moving forward and backward is always constant by the air cylinder 40 connected by the air compressor 30 and the air hose 20. In the case of a curved platform, the protruding length of the scaffold 60 projected by the air cylinder 40 is shortened and a gap is generated, and even if the projected length of the scaffold 60 is slightly increased, the train Since a collision occurs when entering or leaving, there is a problem that a safety accident is weighted instead.

In addition to this, the safety platform of the subway platform as described above, when a train enters or departs with the platform protruding, the train and platform are collided by the malfunction of the control device, and the platform is lifted. There is a disadvantage that a safety accident occurs.

In addition, a separate air compressor 30 and air hose 20 are embedded in the landing, and an air cylinder 40, rails 50 on which the scaffold is transferred to both sides, and a number of bearings B are installed inside the scaffolding support base 11. Therefore, there is a problem that it is difficult to manufacture and install a safety scaffold due to a complicated structure.
