The present invention relates to a PSD (Platform Sliding Door) to be installed on the platform of the subway, and more particularly to a PSD that is easy to adjust the installation height of the door.

In general, a PSD is a safety device that is installed between a track and a platform in a subway or light rail platform so that the door can be opened and closed by interlocking with a door of an electric vehicle. It also reduces noise, dust and strong winds caused by trains.

Utility Model No. 288385, Door Hanger for Automatic Door Opening and Closing, and Registration Utility Model No. 389410, PSD Opening and Closing for Subway, and as shown in FIG. It is coupled to the rail provided in the frame to support the load of the door and slide the door, and the lower part of the door is usually provided with a separate rail that simply prevents the door from being separated, and the door is spaced apart from the platform bottom by a predetermined distance. This minimizes the factors that can hinder the slide movement of the door.

The frame is continuously installed along the platform of the platform, and a pair of doors are installed in the frame at predetermined intervals to form an access space.

There are many tracks in the platform where the PSD is installed, and the platform floor where the frames are installed continuously is not easily identified, but the height is not constant and is curved.

As such, the bottom of the platform on which the PSD is installed is not flat, but is bent, so that it is difficult to install the door in the frame, thereby causing a problem in the stability of the installed door.

In more detail,

Since a plurality of doors installed in the frame are manufactured in large quantities, the upper and lower lengths are the same, and the frame is installed on the platform so that its upper portion is in a straight line (ie, parallel to the ground), and the bottom of the platform is not flat but curved. That is, the installation space of the frame on which the door is installed is not constant, so that the vertical length is longer than the vertical length of the door in some places, and the vertical length is shorter than the vertical length of the door in other places.

Therefore, if the vertical length of the door is longer than the installation space of the frame, the door cannot be installed in the frame. If the door is forcibly installed, the lower part of the door is in contact with the bottom of the platform and the slide movement of the door is not free.

If the door is shorter in length, it is not a problem to install the door in the frame.However, depending on the difference in the length of the door and the installation space, there is an ups and downs in the gap between the lower part of the door and the bottom of the platform. The influence of the external force acting in the direction is different for each door according to the gap difference, thereby causing a problem in the stability of the entire door, more largely the overall stability of the PSD.

In order to solve this problem, the height of door should be adjusted arbitrarily. The above-mentioned registered utility model No. 288385, "door hanger for automatic door opening and closing device," forms a long hole in a fixed bracket and inserts a rotating shaft of the roller into the long hole to change the position of the roller. The height can be adjusted.

As such, in the method of adjusting the installation height of the door using a long hole, the installation height of the door is difficult to be maintained for a long time. This is because the roller supports the load of the door and the door is constantly subjected to an external force acting in the horizontal direction by the strong wind generated when the electric vehicle enters the vehicle, so that the roller is pushed downward along the long hole as time passes.

And the conventional PSD does not have a separate means for preventing the door from swinging in the horizontal direction.

As described above, when the electric vehicle enters, strong wind is generated to shake the door in a horizontal direction. There is no means for preventing the PSD, and the PSD is broken, and the roller is separated from the rail. If there is a strong wind, the door may be removed from the frame and a safety accident may occur.

For reference, the release prevention roller provided in the registered utility model No. 288385 "door hanger for automatic door opening and closing device" is not intended to prevent the swing of the door, it is simply to prevent the departure of the roller.

The present invention has been made to solve the problems of the conventional PSD as described above, and an object of the present invention is to provide a PSD that can easily adjust the installation height of the door and can prevent the door from shaking due to strong wind. .

PSD of the present invention for achieving the above object,

frame; A door for opening and closing an entrance space of the frame; A rail unit provided above the frame; A connection member provided above the door; In the PSD comprising a; upper roller portion connected to the door through the connecting member to support the load of the door so that the door is spaced apart from the bottom surface, and moved along the rail portion;

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the PSD according to an embodiment of the present invention, the frame (F) provided between the platform (P) and the track of the subway, the door for opening and closing the installation space of the frame (F) (D), rollers (10, 20, 30) for sliding the door (D), and rails (40, 50, 60) for the rollers (10, 20, 30).

The frame (F) is formed continuously along the platform (P), and is provided with a passenger entrance at a predetermined interval, in particular for the position of the door of the train carriage.

The door (D) is installed in the access space of the frame (F) to slide the door in a direction in which the pair is opposed to open and close the access space.

The upper portion of the frame (F) is built with a driving means (not shown) for sliding the door (D).

And the upper roller portion and the rail portion for sliding the door (D),

The upper roller portion is mounted to the connecting member 70, the first roller 10 for supporting the load of the door (D), and the second roller 20 for preventing the upper direction of separation of the installed door (D) ) And a third roller 30 for coping with the horizontal load acting on the door D (ie, an external force acting in the direction of the platform P on the track by strong wind or the like).

The rail unit is mounted on the upper side of the frame (F), and the first rail 40, the second rail 50, the third rail (for each of the first, second, third rollers 10, 20, 30) 60).

For reference, the lower part of the PSD of FIG. 1 is provided with a separate guide part (not named) for preventing the door from being separated and moving stably.

The groove 16 of the first roller 10 is in contact with the protrusion 41 of the first rail 40 at the bottom, the groove 26 of the second roller 20 is the second rail at the top In contact with the protrusion 51 of the 50, the third roller 30 is in contact with the both sides of the supporting portion 61 of the third rail 60 is restrained.

The first roller serves to support the overall load of the door (D),

The second roller 20 is spaced apart from the first roller 10 by a predetermined distance in the direction of gravity, and the protrusions 51 are inserted into and coupled to the grooves 26 so that the first roller, and eventually the door, Prevent deviations, enable stable movement,

The third roller 30 is arranged such that the rotational shaft 31 is perpendicular to the rotational shaft 11 of the first roller 10 so as to be spaced apart from the first roller 10 by a predetermined distance. Movement in the horizontal direction is constrained by the rail 60 to prevent the door from shaking or leaving the rail from the load acting in the horizontal direction with respect to the door D when the train enters or the wind blows.

As a result, the first roller 20 and the third roller 30 guide the stable slide movement of the door D together with the first roller 10 and at the same time prevent the door D from escaping or swinging from the rail portion. do.

The roller accommodating groove 45 formed by the first rail 40 and the second rail 50 has openings through which the rollers 10 and 20 enter and exit from the side of the gravity direction. Therefore, the first roller 10 and the second roller 20 are inserted into the roller receiving groove 45 from the side with respect to the gravity direction, and contact the first rail 40 and the second rail 50, respectively,

The roller restraint groove 65 of the third rail 60 has a roller entrance formed at a lower side in the gravity direction. Therefore, the third roller 30 is inserted into the roller confining groove 65 from the lower side is coupled.

Here, the roller entrance of the third rail 60 may be formed above in the direction of gravity. In this case, only the third roller 30 is inserted upward, and the supporting direction and the moving direction are the same as those formed below.

Components and processes for adjusting the installation height of the door (D) will be described with reference to FIGS. 3a mainly viewed from the front and FIG. 3b seen from the front of the combination of the roller and the connection member.

First, referring to FIGS. 3A and 3B, the connection member 70 is fixedly coupled to the upper portion of the door D and vertically connected to the fixed plate portion 71 and has a roller 10. , 20, 30 is made of a mounting plate portion 72 is mounted.

Each roller 10, 20, 30 is composed of a rotating shaft (11, 21, 31) and the outer ring (12, 22, 32) is coupled to the rotating shaft (11, 21, 31), respectively. And the assembly coupling of each roller outer ring and the rotating shaft will usually be made by a known method using a snap ring.

The mounting position of the first roller 10 and the second roller 20 is variable within a predetermined distance in the direction of gravity in the fixed plate portion 71, whereby the installation height of the door D is adjusted.

Here, the first roller 10 supporting the load of the door D directly adjusts the installation height of the door D, and the second roller 20 according to the change of the fixed position of the first roller 10. Mounting position is changed to be coupled to the second rail (50).

The component for changing the mounting position of the first roller 10 is a fixing pin 13 connecting the rotating shaft 11 of the first roller 10 and the fixing plate portion 71 of the connecting member 70, The fixing pin 13 is eccentric with the pivot shaft 11 of the first roller 10. Accordingly, when the fixing pin 13 is rotated, the position of the first roller 10 is changed by moving the pivot shaft 11 in the gravity direction within a predetermined distance range.

Components for changing the fixed position of the second roller 20 is the oblique long hole 70 formed in the oblique direction with respect to the direction of gravity in the fixed plate portion 71 of the connecting member 70, and the second roller 20 It is a fixing pin 23 is inserted into the rotating shaft 21 and the oblique long hole 70 of the fixed plate portion 71. Here, the fixing pin 23 does not have to be eccentric with the pivot shaft 21 like the first roller 10.

The process of adjusting the installation height of the door (D) by using the first roller 10 and the second roller 20 is as follows.

First, the first roller 10 moves upward in the gravity direction so that the first and second rollers 10 and 20 are easily accommodated in the roller receiving groove 45, and the second roller 20 moves downward. Let's do it.

Next, the door D is coupled to the frame F so that the first and second rollers 10 and 20 are inserted into the roller accommodation groove 45.

Next, lift the door slightly while the load of the door D is acting on the first rail 40 of the frame F through the first roller 10, and the required distance from the platform P (for example, 5 mm). ~ 10mm) by rotating the fixing pin 13 of the first roller 10 in a state of being spaced and leveled

Since the fixing pin 13 is eccentric with respect to the pivot shaft 11 (that is, it is not arranged on a virtual same axis)

According to the rotation of the fixing pin, the center of the first roller 10, that is, the pivot shaft 11, may be adjusted to a distance from the platform P (in other words, a distance from the first roller).

In a state in which the outer ring 12 of the first roller installed in at least two upper portions of the door is in contact with the protrusion 41 of the first rail 40 so as to fix the adjusted height and horizontality of the door.

When the bolt 15 coupled to the fixing pin 13 of the first roller is tightened using a tool such as a spanner or a hexagon wrench,

The first roller 10 is fixed, and thus the height and the horizontal state of the adjusted door are fixed.

Next, the fixing pin 23 is moved along the oblique long hole 73 of the mounting plate 72 to adjust and fix the second roller 20.

In a state where the upper portion of the second roller 20 is in contact with the protrusion 51 of the second rail 50

Also, by using a tool such as a spanner, the nut 25 is tightened to fix the height-adjusted second roller.

Here, since the second roller 20 does not support the load of the door D, the long roller 73 is used to easily move up and down, and the first roller 10 supports the load of the door D. After the use of the fixing pin 13 is eccentric so that its position is not changed by the load of the door (D).

Subsequently, as shown in FIGS. 3A and 3B, the outer ring 32 of the third roller 30 is positioned in the roller restraint groove 65 formed by both supporting portions 61 of the third rail 60. The rotation of the rotating shaft 31 of the third roller 30 and the first roller 10 by fixing the mounting piece 33 connected to the outer ring 32 via the rotating shaft 31 to the mounting plate portion 72. Installation is completed so that the coaxial 11 is perpendicular to each other so that the third roller 30 is arranged in the direction perpendicular to the first roller 10.

As a result, the PSD according to the present invention can be stably opened and closed without shaking or leaving the rail part in the vertical and horizontal loads due to wind or vibration, and is easy to install and maintain.

In the above description, the height and horizontal adjustment method of the door constituting the PSD according to the present invention is mainly focused on the first roller 10 having the fixing pin 13 for coupling the pivot shaft 11 and the connecting member 70 to be eccentric. As described above, the concept of the second and third rollers including the first roller may be universally applied to other sliding doors in addition to the PSD, and in the case of a specific hanger type sliding door applying the same method. It should be interpreted as falling within the protection scope of.

As described above, the present invention can maintain a constant distance between each door and the platform bottom by a simple operation even if the platform bottom is not flat,

By supporting the door in double and triple by the second roller and the third roller, it is possible to prevent the first roller from being separated from the rail, and to minimize the door shaking due to the strong wind caused by the entry of the vehicle. There is an effect that can prevent the removal or breakdown of the PSD.

In the above description of the present invention has been described with respect to the easy to adjust the height PSD having a specific shape and structure with reference to the accompanying drawings, the present invention can be variously modified and changed by those skilled in the art, such modifications and changes are It should be interpreted as falling within the protection scope of the invention.
