Description

Technical Field

[0001] This utility model relates to the field of subway equipment technology, and in particular to an anti-falling clip for an evacuation platform plate. Background Technology

[0002] Evacuation platforms are installed on the tunnel sidewalls, fulfilling the functions of safe evacuation and rail transit maintenance. To ensure personnel safety, baffles need to be installed at the platform edges to restrict movement and increase the safety and reliability of the evacuation platform. Traditional installation methods involve directly welding the baffles to the platform panels, which is inefficient and requires operations such as limiting the evacuation platform, on-site drilling, and welding. The installation process is cumbersome, inefficient, and requires highly skilled construction personnel. Furthermore, subsequent maintenance, replacement, and adjustments are inconvenient, and long-term use can lead to problems such as loosening and deformation of weld points, requiring frequent maintenance and increasing maintenance costs. Utility Model Content

[0003] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0004] An anti-fall clip for an evacuation platform includes a fixing frame and a platform, the platform being disposed on the upper end face of the fixing frame. It also includes a baffle body, the upper part of which has a limiting upper ear plate abutting against the left or right end face of the platform. The upper end face of the baffle body abuts against the front end face of the platform. The lower part of the baffle body has a connecting lower ear plate, which is fixedly connected to the fixing frame.

[0005] Furthermore, both the connecting lower ear plate and the fixing frame are provided with through holes. When the connecting lower ear plate abuts against the side of the fixing frame, the two through holes are coaxial, and bolts are installed in the through holes.

[0006] Furthermore, the lower end face of the platform plate is provided with a connecting column, which is detachably connected to the fixing frame via a hook.

[0007] Furthermore, one end of the hook is a hook portion that is adapted to engage with the connecting column, and the other end of the hook is provided with an external thread and is connected to a pressure plate via a nut.

[0008] Furthermore, the upper end face of the pressure plate abuts against the lower end face of the fixing frame.

[0009] The beneficial effects of this utility model are:

[0010] 1. Setting the upper limiting ear plate in the gap between the two platform plates can effectively prevent the platform plates from moving longitudinally; the end face of the baffle body abuts against the front face of the platform plate, and the baffle body is fixedly connected to the fixed frame by connecting the lower ear plate can effectively prevent the platform plates from moving laterally; both can improve the safety and reliability of the structure.

[0011] 2. Using baffles of different sizes, i.e., baffles of different heights, angles, or positions, can adapt to different platform structures and resolve installation errors.

[0012] 3. No on-site drilling or welding is required; assembly can be performed directly, resulting in fast installation.

[0013] 4. The structure is not easily damaged, allowing for modular installation. In case of partial damage, individual parts can be quickly replaced, reducing maintenance costs. Attached Figure Description

[0025] refer to Figures 1-5 As shown, one embodiment of this utility model is as follows:

[0026] An anti-fall clip for evacuation platform panels includes a fixing frame 4 and a platform panel 5. The platform panel 5 is disposed on the upper end face of the fixing frame 4. In this invention, one end of the fixing frame 4 is fixed to the tunnel wall by anchor bolts, and the other end extends outward to place the platform panel 5. In actual use, several fixing frames 4 are evenly installed along the length of the tunnel, and the left and right ends of each platform panel 5 are placed on adjacent fixing frames 4 respectively. That is, the left end of the platform panel 5 is placed on the fixing frame 4 to its left, and the right end of the platform panel 5 is placed on the fixing frame 4 to its right. In other words, several platform panels 5 are placed sequentially on several fixing frames 4, and each fixing frame 4 holds one end of two platform panels 5, with a gap between the two platform panels 5 on the same fixing frame 4.

[0027] Specifically, it also includes a baffle body 1, which is a rectangular plate. The upper end face of the baffle body 1 abuts against the front end face of the platform plate 5 to limit the platform plate 5 and prevent it from moving back and forth. The upper part of the baffle body 1 is provided with a limiting upper ear plate 2, which is perpendicular to the end face of the baffle body 1 and extends into the gap between the two platform plates 5. The limiting upper ear plate 2 abuts against the left or right end face of the platform plate 5, thereby limiting the longitudinal movement of the platform plate 5. The lower part of the baffle body 1 is provided with a connecting lower ear plate 3, which is perpendicular to the end face of the baffle body 1 and abuts against the side of the fixing frame 4. The connecting lower ear plate 3 is fixedly connected to the fixing frame 4 and is used to fix the baffle body 1 to the fixing frame 4.

[0028] In this utility model, the lower connecting ear plate 3 is fixedly connected to the fixing frame 4 by bolt connection. Specifically, both the lower connecting ear plate 3 and the fixing frame 4 are provided with through holes. When connecting the lower connecting ear plate 3 and the fixing frame 4, the through holes on the lower connecting ear plate 3 and the through holes on the fixing frame 4 are made coaxial. That is, when the sides of the lower connecting ear plate 3 and the fixing frame 4 abut against each other, the two through holes are coaxial. After the two through holes are coaxial, bolts 6 are set in the through holes and fixed by bolt connection.

[0029] In this utility model, in order to fix the platform plate 5 to the fixing frame 4, the lower end face of the platform plate 5 is provided with a connecting post 7. The connecting post 7 can be fixedly connected to the lower end face of the platform plate 5 by welding or threaded connection. The connecting post 7 is detachably connected to the fixing frame 4 by a hook 8. Specifically, one end of the hook 8 is a hook part, which is adapted to engage with the connecting post 7 and hangs on the connecting post 7. The other end of the hook 8 is provided with an external thread, and this end passes through the pressure plate 10 and is threaded to a nut 9. The nut 9 applies a pre-tightening force to the pressure plate 10, so that the upper end face of the pressure plate 10 can tightly abut against the lower end face of the fixing frame 4, and the hook 8 pulls the platform plate 5 down to fix the platform plate 5.

[0030] The following points need to be explained:
