Description

Tram platform safety device including damage protection function

The present invention relates to a trolley platform safety device including a damage protection function, and particularly relates to a tram platform safety device including a damage protection function capable of preventing a track and a roller damage phenomenon occurring during a process in which a rope is swayed in a front-rear direction (rope) Rood Screen Door, RSD).

Referring to Figure 1, a typical tram platform safety device includes a plurality of lifting units 100 that are mounted at selected locations between the entrance and exit of the trolley into the platform, and a moving body 120 that can be moved up and down within the interior of the lifting unit 100. The direction is moved in a manner; and at least two or more cords 200 are mounted in the horizontal direction so as to be connected to each other.

2 and FIG. 3, wherein the lifting unit 100 forms a main body along a vertical direction, a support portion 110 is formed in a vertical direction inside the main body, and a rail 111 is fixed in a vertical direction on one side of the supporting portion 110. A roller 121 that rotates in a state of being in contact with the rail 111 in a state of being in contact with the rail 111 is formed on one side of the moving body 120; the moving body 120 is moved in the vertical direction along the support portion 110.

Referring to FIG. 4, the existing manner causes the roller 121 to rotate in the front-rear direction due to the external force formed when the passenger holds the rope 200 for pushing or pulling, thereby forming severe friction with the rail 111 and thus Problems that cause wear and damage. That is, although when When the roller 121 moves in the up and down direction along the rail 111, the rolling motion is performed, but when the rotation occurs in the front-rear direction, friction and resistance are caused by the surface contact state with the rail 111, thereby causing the rail 111 and the roller. Wear or damage to the shaft 121. In particular, when the rail 111 and the roller 121 are worn or damaged by friction, problems such as strong vibration, friction noise, and sway are caused during the movement of the moving body 120 and the rope 200 in the up and down direction.

Further, there is a possibility that the rail 111 is bent due to thermal expansion caused by friction with the roller 121, or the connecting member such as the bolt 111a for fixing the rail 111 is broken due to thermal expansion and further causes the rail 111. Separation problem. At the same time, since the rope 200 cannot smoothly move in the up and down direction, it is not possible to effectively restrict the entry and exit of passengers.

The trolley platform safety device to which the present invention is applied includes: a plurality of lifting units 100 mounted at selected positions between the entrance and the exit of the trolley into the platform; and moving the main body 120 to be able to move up and down within the lifting unit 100 Mounting in a directionally moving manner; and at least two or more cords 200 are mounted in a horizontal direction in such a manner as to interconnect the moving bodies 120; wherein the lifting unit 100 forms a body in a vertical direction, on the inner side of the body Forming the support portion 110 in a vertical direction; forming a vertical direction on one side of the support portion 110, When the rope 200 is subjected to an external force and is swayed in the front-rear direction, it rotates in the horizontal direction together with the roller 121, thereby preventing the rail 111 from rubbing against the roller 121; forming a side along the side of the moving body 120 The track 111 is moved by the roller 121 in the vertical direction.

The elevating unit 100 in the present invention is a means for guiding the moving body 120 and the rope 200 so as to be able to smoothly move in the vertical direction, and the rope 200 is a means for restricting entry and exit of passengers. Detailed descriptions of the working principle and the specific structure of the technology generally used in the related art will be omitted herein.

In particular, when the rail 111 is firmly fixed to one side of the support portion 110 by the bolt 111a in the conventional manner, no problem is caused in the process of moving the roller 121 in the up and down direction, but When the rope 200 is shaken in the front-rear direction due to a passenger or an obstacle, the roller 121 will rotate in the horizontal direction in a state of being in contact with the surface of the rail 111, resulting in strong friction and noise.

Therefore, in order to solve the conventional problem as described above, the rail 111 of the present invention is caused to be swayed with the roller 121 when the rope 200 is shaken in the front-rear direction due to an external force when it collides with a passenger or an obstacle. Rotating together in the horizontal direction prevents friction and noise with the roller 121.

The upper and lower portions of the body include support members 112 for assembling the upper and lower ends of the rails 111 to enable the rails to rotate in the horizontal direction. The inner side of the support member 112 includes a bearing 112a for contacting the upper or lower end of the rail 111 to enable the rail to rotate in the horizontal direction. A margin space 112b that allows the rail to move in the up and down direction when the rail 111 thermally expands is formed inside the support member 112, thereby preventing the rail 111 from being bent or deformed due to thermal expansion.

The upper end and the lower end of the rail 111 include the elastic member 111b, which can not only minimize the vibration transmitted to the rail 111 during the movement of the roller 121, but also the rail 111 moving in the up and down direction due to thermal expansion. When the support member 112 collides, it acts as a buffer. The elastic member 111b can be made of various forms and materials such as a spring or a cushion.

An insertion groove for inserting the rail 111 in the vertical direction is formed at one side of the support portion 110. The insertion groove provides sufficient supporting force for the circular rail 111 to be inserted into the inside thereof to avoid detachment from the left and right direction upon rotation.

The inner side of the insertion groove includes a sliding member 113 for contacting the rail 111 to enable the rail to slide. The sliding member 113 can smoothly rotate by guiding the guide rail 111 in a state of being in contact with the rail 111 by a member such as a sleeve.

Referring to Fig. 7, by the present invention, when the rope 200 is shaken in the front-rear direction, the moving body 200, the rail 111, and the roller 121 can be simultaneously rotated in the horizontal direction, thereby preventing the rail 111 and the roller 121. Wear and damage between them.
