Abstract

PURPOSE: A method for removing a gap between a railway car and a platform is provided to protect passengers from such an accident as taking a false step. CONSTITUTION: A gap between the front end of a platform(10) and railway cars(20) is closed by adhering elements(30). The adhering members are connected to support bars(31) and protruded by coil springs(32). When the railway cars enter the platform, the lateral faces of the railway cars are adhered to the lower faces of the entrance doors facing the front end of the platform. Preferably, the protruded length of the adhering element is slightly larger than the gap(L) between the railway car and the platform. To reduce contact friction, rotatable rollers(33) are installed in the front faces of the railway cars. The protruded length of the adhering element is adjusted by a restraining in. By removing the gap between the railway car and the platform, safety of passengers is secured.

Description

Method for closing the gap between the electric train and the platform}

The present invention relates to a method for eliminating the gap between a train and a platform of a subway.

In the case where the platform of the subway has a curved shape, an interval between the linear electric train and the curved platform is large, causing a lot of dangers when getting on and off.

SUMMARY OF THE INVENTION The present invention provides a method of eliminating the gap between a curved platform and a train, thereby eliminating the risk of falling off during getting on and off, and providing a method for eliminating the gap between the train and the platform that can enhance the safety of the passengers. It is put.

1 is a plan view illustrating the present invention.

2 is a plan view illustrating an embodiment of the present invention.

3 is an explanatory diagram of the main parts of FIG. 2;

4 is a sectional view of the main parts of FIG. 3;

Figure 5 is a perspective view showing the structure of the contact elements used in the present invention.

6 is a cross-sectional view showing another embodiment of the present invention.

The present invention will be described in detail with reference to the exemplary drawings.

FIG. 1 is a plan view illustrating a state in which the present invention is applied, and shows that the gap between the tip of the platform 10 and the electric vehicles 20 is closed by the contact elements 30 as indicated by the dotted lines. .

FIG. 2 is an enlarged view of FIG. 1 and shows a state in which the distance between the landing 10 and the electric vehicle 10 is closed by the close contact elements 30 indicated by solid lines.

As shown in FIGS. 3 and 4, the close contact elements 30 protrude by the coil springs 32 through a sieve connected to the support rod 31, so that the electric vehicle 20 enters the platform 10 at the moment when the electric vehicle 20 enters the platform 10. It is in close contact with the side of the 20, that is, the lower side of the side of the door in the position facing the landing 10.

At this time, the protruding length of the contact elements 30 may be slightly larger than the normal distance L between the electric vehicle 20 and the platform 10, and the front surfaces of the contact elements 30 may be rotatable to reduce contact friction. It is preferable to install the roller 33, and as shown in FIG. 4, the protruding length of the contact elements 30 is controlled by the suppressor pin 34. As shown in FIG.

In addition, it is advantageous in terms of construction and repair that the contact element 30, the support rod 31 and the spring 32 to be operated in the casing (40).

The contact elements 30 have a roller 33 rotating on the front surface as shown in FIG. 5, and are connected in a chain form by a connecting pin 35 so as to be connected with the forward movement by the spring 32. 35) Some circular motions can be made, and both ends must be semi-circular to minimize friction during initial contact and to prevent damage from collision.

6 illustrates another embodiment of the present invention, in which the close contact elements 30 are mounted on the cage 10 in the lower portion of the electric vehicle 20 so as to be sunk toward the landing 10.

In FIG. 6, the close contact elements 30 may be operated in a mechanical or electrical manner by the driver's operation as soon as the electric vehicle 20 enters the landing 10.

In the present invention, the contact elements 30 may be operated by using a hydraulic device or any other means other than the spring 32, and the individual contact elements 30 are separated instead of the chain form as illustrated. It can also be operated independently from the state.

In addition, the present invention may be applied to the whole landing 10, or may be applied only to a predetermined position of getting on and off the landing 10.

The present invention is very simple in the structure of the mechanical element used in the present invention, and the installation method is also easy, so that the present invention can be easily applied to the platform and train of the subway at low cost.

In addition, the present invention can completely prevent the gap between the platform and the electric vehicle in a very simple way, it is possible to completely ensure the safety of passengers when getting on and off.
