Description

Technical Field

[0001] The utility model relates to an integral DCU assembly structure of a platform door, belonging to the technical field of traffic equipment. Background Art

[0002] The existing local control DCU of the platform door is to install the DCU box directly on the connecting bracket in the side box of the platform door. Due to the needs of technological development, the transformation of the existing old platform door DCU needs to add a CAN transfer module and upgrade the DCU. To replace the new platform door DCU and add the CAN transfer module, the operator directly replaces and installs it in the side box of the platform door, which requires re-drilling and installation. The replacement can only be carried out between 0:00 and 3:00 at night when the subway is closed. Therefore, the operator needs to operate and install quickly. Due to the difficulty of on-site operation and the short time, it is difficult to ensure the installation accuracy and quality, which brings challenges and difficulties to the installation work.

[0003] Therefore, a platform door integral DCU assembly structure that is convenient, quick to install and easy to ensure installation quality has become a goal pursued by technical personnel in this field. Summary of the invention

[0004] The utility model is to solve the problem that the replacement of the platform door DCU in the platform door side box and the addition of a CAN network transfer module cause difficulties in on-site installation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an integral DCU assembly structure for a platform door, comprising: a platform door DCU box body and a CAN network transfer module box body, and a platform door side box for installing the platform door DCU box body, characterized in that it also includes a mounting frame, wherein: the platform door DCU box body and the CAN network transfer module box body are fixedly mounted on the first mounting plate of the mounting frame by screws, and the platform door DCU box body and the CAN network transfer module box body are installed in the platform door side box through the mounting frame.

[0006] The overall DCU assembly structure of the platform door is a preferred solution, wherein: the first mounting plate of the mounting frame is a vertically arranged flat plate, and the installation also includes a second mounting plate, which is arranged vertically on the top of the first mounting plate and the first mounting plate, and the second mounting plate is provided with three mounting holes for connecting with the platform door side box, and the mounting holes correspond to the positions of the DCU fixing holes on the connecting bracket in the platform door side box.

[0007] The platform door integrated DCU assembly structure is a preferred solution, wherein: the first mounting plate and the second mounting plate are an integrated structure.

[0008] As a preferred solution, there is a space between the upper ends of the platform door DCU box body and the CAN network transfer module box body and the bottom of the second mounting plate. Preferably, the height of the space is greater than or equal to 18 mm. A certain space is left between the platform door DCU box body and the CAN network transfer module box body and the bottom of the second mounting plate to facilitate their connection with the connection bracket of the platform door side box.

[0009] The utility model adopts the above technical solution, by integrating the modified platform door DCU box body and the CAN network transfer module box body together, and by setting up a mounting frame, the platform door DCU box body and the CAN network transfer module box body can be first fixed on the mounting frame in the factory, and then the mounting frame can be fixed in the side box on site, so as to achieve the purpose of one-time installation of two parts, thereby greatly saving installation time and reducing installation difficulty.

[0010] In particular, by arranging a second mounting plate on the upper end of the first mounting plate of the mounting frame and opening mounting holes on the second mounting plate, the mounting holes correspond to the existing DCU mounting holes in the platform door side box, so that the replacement of the old and new DCUs and the installation of the CAN network transfer module box body can be realized without re-drilling. The installation difficulty and time are greatly reduced, and the DCU replacement and the CAN network transfer module box body can be directly installed at one time without on-site drilling.

[0011] Preferably, the first mounting plate and the second mounting plate are an integral structure, and the mounting frame is formed by bending, which can reduce costs.

[0012] In summary, the utility model has a simple structure and reasonable design, and can be processed and assembled in the factory to ensure assembly quality and precision. After processing and assembling in the factory, it is transported to the site and installed inside the side box of the half-height platform door. On site, it only needs to fix and wire the whole with the three original DCU mounting holes of the side box. It can improve the efficiency of on-site assembly, and when parts need to be repaired and replaced, it can reduce working time and improve the efficiency of emergency disposal.
