Description

Technical Field

[0001] The present invention relates to the technical field of replacement of platform screen door bodies of subway stations, and particularly relates to a safety protection device for replacing platform screen door bodies of subway stations. Background Art

[0002] In the prior art, the replacement of platform screen door bodies of subway stations mainly relies on manual operation, and a suction cup tool is used to lift and install the door body. Especially during the installation and adjustment process, the operator needs to hold the door body for a long time to keep it in a lifted state until the door body is completely installed and firmly fixed before relaxation. Due to the large area and heavy weight of the door body (especially the fixed doors at the car body connection and the standard fixed doors), the operator needs to consume a large amount of physical strength for handling and installation.

[0003] Secondly, when replacing the platform screen door body, the operation area is limited, and the operator can only operate on the platform side, and there are no effective protection measures on the track side. There is a risk that the door body will fall or tilt towards the track area during handling and installation. The existing suction cup tool can only operate on the platform side and cannot provide support on the track side, resulting in the inability to effectively control the safety risks during the replacement of the door body. Summary of the Invention

[0004] The purpose of the present invention is to provide a safety protection device for replacing platform screen door bodies of subway stations to solve the above problems existing in the prior art.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A safety protection device for replacing platform screen door bodies of subway stations includes a fixing plate, a connecting plate, and two L-shaped support plates. The upper part of the fixing plate is movably connected to the door head and door machine beam, the lower part of the fixing plate is horizontally movably connected to the connecting plate, and both ends of the connecting plate are movably connected to the L-shaped support plates for holding the door frame of the door body; the lower part of the fixing plate points to the track area so that the L-shaped support plates can hold the door frame of the door body in the track area.

[0007] The beneficial effects of the present invention are: by setting the fixing plate, the connecting plate, and the L-shaped support plates to fix the door body on the door head and door machine beam, during the installation and debugging process, the staff does not need to hold the door body for a long time, saving the physical strength of the operator; the fixing plate pointing to the track area enables the connecting plate and the L-shaped support plates to extend into the track area to provide support inside the track area, which can prevent the door body from falling or tilting into the track area during handling and installation.

[0008] On the basis of the above technical solution, the present invention can be further improved as follows.

[0009] Further, there are two fixing plates, and each fixing plate is multi-segmented. The upper part is connected to the door head and door machine beam by bolts, and the lower part is connected to the connecting plate by bolts.

[0010] The fixing plate is a multi - segment bow - shaped structure, and the lower part points to the track area.

[0011] The beneficial effects of the above are as follows: The multi - segment structure has high strength; the bolt connection is stable; when the middle part of the bow - shaped structure bears the force between the fixing plate and the connecting plate, it is not easy to deform.

[0012] Furthermore, two vertical adjustment grooves are spaced apart in the middle of the connecting plate, and horizontal adjustment grooves are respectively provided at both ends of the connecting plate. The connecting plate is bolt - connected to the fixing plate through the vertical adjustment grooves, and the two ends of the connecting plate are bolt - connected to the L - shaped support plate through the horizontal adjustment grooves.

[0013] The beneficial effects of the above are as follows: The connecting plate enables the L - shaped support plate to be finely adjusted in both the horizontal and vertical directions to ensure the precise matching of the position of the L - shaped support plate with the door body. By adjusting the bolts, the operator can quickly adjust the position of the L - shaped support plate to adapt to different models of platform doors. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0023] Embodiment 1

[0024] As Figures 1 to 2 shown, a safety protection device for replacing the door body of a subway platform door includes a fixing plate 1, a connecting plate 2, and two L-shaped support plates 3. The upper part of the fixing plate 1 is movably connected to the door head and door machine beam 6, the lower part of the fixing plate 1 is horizontally movably connected to the connecting plate 2, and both ends of the connecting plate 2 are movably connected to the L-shaped support plates 3 for supporting the door frame of the door body 7; the lower part of the fixing plate 1 points to the track area so that the L-shaped support plates 3 can support the door frame of the door body 7 in the track running area.

[0025] By setting the fixing plate 1, the connecting plate 2, and the L-shaped support plates 3, the door body 7 is fixed to the door head and door machine beam 6. During the installation and debugging process, the staff does not need to hold the door body 7 for a long time, saving the physical strength of the operators; the fixing plate 1 pointing to the track area enables the L-shaped support plates 3 to extend into the track area and provide support inside the track area, which can prevent the door body 7 from tipping or falling into the track area during handling and installation.

[0026] Embodiment 2

[0027] As Figures 1 to 2 shown, this embodiment is a further improvement on Embodiment 1, specifically as follows:

[0028] There are two fixing plates 1, and each fixing plate 1 is of a multi-section type. The upper part is connected to the door head and door machine beam 6 by bolts, and the lower part is connected to the connecting plate 2 by bolts. The multi-section structure has high strength; the bolt connection is stable.

[0029] The fixing plate 1 is of a multi-section bow-shaped structure, and the lower part points to the track area. When the middle part of the bow-shaped structure has high strength to bear the force between the fixing plate 1 and the connecting plate 2, it is not easy to deform; and the upper part is hooked on the door head and door machine beam 6 to achieve a stable connection with the door head and door machine beam 6.

[0030] Embodiment 3

[0031] As Figure 3 shown, this embodiment is a further improvement on any one of Embodiments 1 to 2, specifically as follows:

[0032] Two vertical adjustment slots 21 are spaced apart in the middle of the connecting plate 2, horizontal adjustment slots 22 are respectively opened at both ends of the connecting plate 2, the connecting plate 2 is bolted to the fixing plate 1 through the vertical adjustment slots 21, and both ends of the connecting plate 2 are bolted to the L-shaped support plates 3 through the horizontal adjustment slots 22.

[0033] The connecting plate 2 enables fine-tuning of the L-shaped support plate 3 in the horizontal and vertical directions to ensure precise matching of the position of the L-shaped support plate 3 with the door body 7. By adjusting the bolts, the operator can quickly adjust the position of the L-shaped support plate 3 to adapt to different models of platform doors.

[0034] Embodiment 4

[0035] As Figures 1 to 2 shown, this embodiment is a further improvement based on any one of Embodiments 1 to 3, specifically as follows:

[0036] After the L-shaped support plate 3 passes through the gap between the portal lintel 8 and the brush 10 from below in the track area and then is fixedly connected to the connecting plate 2. It lifts the door frame of the door body 7 and adapts to the structure of the door body 7 at the same time, with better support.

[0037] It further includes a rubber sleeve 4, and a rubber sleeve 4 is movably sleeved outside the L-shaped support plate 3. It avoids direct contact between the door body 7 and the device and prevents secondary damage to the door body 7.

[0038] Embodiment 5

[0039] As Figures 1 to 2 shown, this embodiment is a further improvement based on any one of Embodiments 1 to 4, specifically as follows:

[0040] It further includes an H-shaped limit insertion block 5, and the distance between the lower two legs of the H-shaped limit insertion block 5 matches the distance from the outside of the threshold 9 to the limit slot in the middle of the threshold 9. Before installing the door body 7, insert the lower legs of the H-shaped limit insertion block 5 into the limit slot in the middle of the threshold 9. When installing the door body 7, the upper legs of the H-shaped limit insertion block 5 limit the door body 7 to achieve rapid alignment of the limit slot of the door body 7 and the threshold 9.

[0041] The steps of installing the door body using this device are as follows:

[0042] On-site measure the vertical distance from the door head door machine beam 6 to the edge of the door frame of the door body 7 to ensure that the L-shaped support plate 3 can provide support for the door frame during the replacement of the door body 7 when it extends into the track area; fix the upper part of the fixing plate 1 on the door head door machine beam 6 through bolts, and pass the L-shaped support plate 3 through the gap between the portal lintel 8 and the brush 10 from below in the track area; preliminarily adjust and tighten the connecting plate 2, and then put on the rubber sleeve 4 outside the L-shaped support plate 3; install the H-shaped limit insertion block 5 on the threshold 9; use a suction cup tool to lift the door body 7 to the installation position, make the door frame below the door body 7 preliminarily correspond to the H-shaped limit insertion block 5, and perform fine-tuning of the connecting plate 2 in the horizontal and vertical directions to accurately position the door body 7 and the threshold 9, complete the bolt tightening, and fix the upper and lower parts of the door body 7 to the portal lintel 8 and the threshold 9 respectively through bolts.
