Description

Technical Field

[0001] This utility model relates to the field of subway platform screen door technology, specifically a subway platform screen door that is easy to maintain. Background Technology

[0002] Subway platform screen doors typically have sufficiently wide maintenance access points at their installation locations to facilitate inspection, repair, and maintenance work by maintenance personnel. For example, openable inspection doors may be installed on the platform side or track side, or a certain width of space may be left between the screen door and the platform edge to allow for personnel operation.

[0003] The existing subway platform screen doors, which are easy to maintain, still have the following problems when in use: In terms of safety protection, people and objects can get caught in the gap between the platform screen doors and the train doors. In order to ensure the safety of train operation, a certain gap is left between the platform screen doors and the train doors. When the flow of people is large, passengers, especially children or people with small stature, are easily caught between the two platform screen doors. Moreover, the existing detection devices may not be able to effectively detect long and flat objects being caught. Utility Model Content

[0004] (a) Technical problems to be solved.

[0005] To address the shortcomings of existing technologies, this utility model provides a subway platform screen door that is easy to maintain, thus solving the problems mentioned in the background art.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a subway platform screen door that is easy to maintain, comprising a door frame mechanism, a laser detection security mechanism disposed at the upper center of the front end of the door frame mechanism, a door panel mechanism assembled inside the door frame mechanism, the door frame mechanism comprising an upper door frame standard module and a lower door frame standard module, a door body standard module fixedly connected between the opposite side walls at both ends of the upper and lower door frame standard modules, an electric guide rail disposed at the center of the opposite end of the upper and lower door frame standard modules, and the door panel mechanism comprising two door panel standard modules symmetrically and slidably assembled between the upper and lower electric guide rails.

[0008] As a further embodiment of this utility model: the laser detection security mechanism includes a central controller fixedly installed in the middle of the front end of the standard module of the upper door frame. Laser detection mechanisms are provided at the front end and on both sides of the central controller. The central controller is electrically connected to two electric guide rails. The laser detection mechanism includes multiple first laser detection sensors arranged horizontally and at equal intervals at the front end of the central controller. The laser detection mechanism also includes a connecting frame fixedly installed at both ends of the central controller. An electric steering seat is fixedly installed at the front end of the connecting frame. A second laser detection sensor is rotatably installed inside the electric steering seat.

[0009] As a further improvement of this utility model: a guide platform is fixedly connected to the front middle of the lower door frame standard module, and multiple anti-slip grooves are opened at the front end of the guide platform. Matching grooves for matching door panel standard modules are opened at the middle of the two door body standard modules facing each other.

[0010] As a further embodiment of this utility model: a first through groove is provided at the front and rear ends of the door standard module, and a first tempered glass plate is fixedly installed in the first through groove; a second through groove is provided between the front and rear side walls of the door panel standard module, and a second tempered glass plate is fixedly installed in the second through groove; guide rail matching assembly grooves are provided at the upper and lower ends of the door panel standard module; and a buffer rubber strip is fixedly connected to one end of each of the two door panel standard modules facing each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by installing a laser detection security mechanism, laser detection sensors are installed on the upper end and both sides of the shielding door, expanding the detection area and effectively detecting long and flat objects. When an object is sandwiched between the two shielding doors, the receiving end cannot receive the detection signal, and an alarm signal can be sent to the driver's cab and the main control room via the central controller. The central controller then controls the electric guide rail to drive the standard module of the door panel to move and open a certain distance, and closes after a delay. If the problem persists after repeated attempts, all doors will be opened.

[0013] 2. In this utility model, by adopting a standardized and modular component interface design, the shielded door system is divided into multiple independent modules, namely the door body standard module, the door frame standard module, and the door panel standard module. Each module can be installed, disassembled, and replaced independently. When a module fails, it can be quickly located and replaced, reducing maintenance time and costs. Attached Figure Description

An electric guide rail 13 is provided at the center of the opposite end of the upper door frame standard module 11 and the lower door frame standard module 12. The door panel mechanism 3 includes two door panel standard modules 31 that are symmetrically slidably assembled between the upper and lower electric guide rails 13. The whole adopts a standardized and modular component interface design, dividing the platform screen door system into multiple independent modules, namely the door body standard module 15, the door frame standard module, and the door panel standard module 31. Each module can be installed, disassembled, and replaced independently. When a module fails, it can be quickly located and replaced, reducing maintenance time and costs.

[0023] The laser detection security mechanism 2 includes a central controller 21 fixedly installed at the front center of the standard module 11 on the upper door frame. Laser detection mechanisms are installed at the front and sides of the central controller 21. The central controller 21 is electrically connected to two electric guide rails 13. Each laser detection mechanism includes multiple first laser detection sensors 22 arranged horizontally and at equal intervals at the front of the central controller 21.

A buffer rubber strip 33 is fixedly connected to each of the two door panel standard modules 31 facing each other, which can buffer when the two door panel standard modules 31 close towards each other.

[0026] The working principle of this utility model is as follows: the electric guide rail 13 can drive the door panel standard module 31 to move, realizing the opening and closing of the shielded door. The whole adopts a standardized and modular component interface design, dividing the shielded door system into multiple independent modules, namely the door body standard module 15, the door frame standard module, and the door panel standard module 31. Each module can be installed, disassembled, and replaced independently. When a module fails, it can be quickly located and replaced, reducing maintenance time and costs. In addition, the whole is equipped with a laser detection security mechanism 2. Laser detection sensors are installed on the upper end and both sides of the shielded door, i.e., the door panel standard module 31, which expands the detection area and can effectively detect flat and long objects. When there is an object between the two shielded doors, the receiver does not receive a detection signal, and an alarm signal can be sent to the driver's cab and the main control room through the central controller 21. The central controller 21 controls the electric guide rail 13 to drive the door panel standard module 31 to move and open a certain distance, and then close after a delay.
