Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit safety and relates to a turnover platform plate mechanism of a longitudinal evacuation platform. Background Art

[0002] In order to facilitate the evacuation of personnel in the station switch area after the end of the tunnel or viaduct, an evacuation platform needs to be set up at the station switch area. Since the switch area needs to install a track switch, the concrete surface of the track bed must be disconnected here. Therefore, the existing evacuation platform will be equipped with a flip plate at the disconnection point of the track bed, so that the flip plate can be opened for maintenance and repair of the switch at the disconnection point.

[0003] For example, a Chinese patent discloses a longitudinal avoidance evacuation platform in a rail transit system [application number: 202110097149.6]. In this solution, since the flip platform plate needs to be flipped, a large gap needs to be left between it and the adjacent fixed platform plate to avoid interference, which requires an additional cover plate to be set at the gap to block the gap. This results in the need to open the cover plate before flipping the flip platform plate, which is time-consuming. In addition, since a large number of pipelines are arranged on the concrete surface of the roadbed, the bottom support frame at the bottom end of the steel bracket will interfere with the pipeline when fixed, making the steel bracket difficult to fix and causing installation difficulties.

[0022] In the above-mentioned flip platform plate mechanism of the longitudinal evacuation platform, a limiting structure is provided between the sliding block and the sliding groove to prevent the sliding block from shifting when the locking block cooperates with the locking hole.

Therefore, the flip platform board 3 and the adjacent fixed platform board 5 can be spliced ​​adjacent to each other. The gap between the flip platform board 3 and the adjacent fixed platform board 5 is very small, and there is no need to set up an additional cover plate to block the gap, making the evacuation platform structure more compact and more convenient to use.

[0039] The flip connecting frame 1 and the flip locking frame 2 are fixed on the roadbed concrete surface through the positioning structures 7 located on both sides of the bottom. They are firmly fixed and the pipeline avoidance area 8 formed between the two positioning structures 7 plays a role in giving way to the pipelines on the roadbed concrete surface, which can prevent interference between the pipelines and the positioning structures 7.

The pipeline avoidance area 8 formed between the support plates 10 on both sides plays a giving way role for the pipelines on the roadbed concrete surface, which can prevent interference with the pipelines. The support plate 10 is fixed to the roadbed concrete surface by applying fixing glue on the bottom end. It is firmly fixed and there is no need to drill fixing holes on the roadbed concrete surface.

[0043] Specifically, combined Figure 1-Figure 3As shown, the articulated structure 6 includes a plurality of articulated shaft brackets 14 arranged at the upper end of the flip connecting frame 1, a hinged connecting shaft 15 is provided at the top end of the articulated shaft bracket 14, and a plurality of articulated bracket assemblies 16 are provided on one end of the flip platform plate 3 close to the flip connecting frame 1, and an articulated sleeve 17 that cooperates with the articulated connecting shaft 15 is provided at the top end of the outer side of the articulated bracket assembly 16, and one side of the articulated bracket assembly 16 close to the flip connecting frame 1 is against the side of the flip platform plate 3.

[0044] The bottom end of the fixed platform plate 5 is provided with a clearance groove 36 adapted to the hinge shaft bracket 14.

[0045] The hinged bracket assembly 16 on the flipping platform plate 3 plays a role in positioning and fixing the flipping platform plate 3. The hinged sleeve 17 at the top of the hinged bracket assembly 16 is hingedly matched with the hinged connecting shaft 15 at the top of the hinged shaft bracket 14, so that the flipping platform plate 3 can be flipped around the hinged connecting shaft 15 at the top of the hinged shaft bracket 14. The hinge is set at the top position of the side of the flipping platform plate 3, which can avoid interference with the adjacent fixed platform plate 5 when the flipping platform plate 3 is flipped around the hinge. The gap between the flipping platform plate 3 and the adjacent fixed platform plate 5 is very small and can be spliced ​​adjacent to each other without the need for an additional cover plate to block the gap.

[0046] The side of the hinged bracket assembly 16 close to the flip connecting frame 1 abuts against the side edge of the flip platform plate 3 to support the flip platform plate 3 .

[0047] Specifically, combined Figure 1 and Figure 4 As shown, the articulated bracket assembly 16 includes an upper positioning plate 18 and a lower positioning plate 19 respectively arranged at the upper and lower ends of the flip platform plate 3, and the upper positioning plate 18 and the lower positioning plate 19 are connected by a plurality of first bolt members 20. The upper positioning plate 18 has an extension section 21 extending toward the outer end of the flip platform plate 3, and the articulated sleeve 17 is arranged on the side of the extension section 21 near the flip connecting frame 1. A limit plate 22 is provided between the upper positioning plate 18 and the lower positioning plate 19, and the lower end of the limit plate 22 is fixedly connected to the lower positioning plate 19. The outer side of the lower end of the limit plate 22 abuts against the side of the flip connecting frame 1, and the inner side of the limit plate 22 abuts against the side of the flip platform plate 3. The upper end of the limit plate 22 is connected to the upper positioning plate 18 through an adjustable member 23.

[0048] The upper positioning plate 18, the lower positioning plate 19 and the limit plate 22 are respectively arranged on the upper end, the lower end and the side of the flip platform plate 3 for positioning and fixing the flip platform plate 3. The upper positioning plate 18 has an extension section 21 extending toward the outward end. The hinge sleeve 17 at the top of the extension section 21 is hingedly matched with the hinge connection shaft 15. The hinge is arranged at the top position of the side of the flip platform plate 3, which can avoid interference with the adjacent fixed platform plate 5 when the flip platform plate 3 is flipped around the hinge connection shaft 15. The gap between the flip platform plate 3 and the adjacent fixed platform plate 5 is very small and can be spliced ​​adjacent to each other without the need for an additional cover plate to block the gap.

[0049] The outer side of the lower end of the limiting plate 22 abuts against the side of the flip connecting frame 1 to support the flip platform plate 3.

[0050] The upper end of the limiting plate 22 is connected to the upper positioning plate 18 through the adjustable part 23 so that the distance between the upper positioning plate 18 and the lower positioning plate 19 can be flexibly adjusted according to the thickness of the flip platform plate 3, and has strong applicability.

[0051] Specifically, combined Figure 1 and Figure 4 As shown, the adjustable member 23 includes an adjusting plate 24 provided at the bottom end of the extension section 21 . The adjusting plate 24 is fixedly connected to the upper end of the limiting plate 22 . The adjusting plate 24 and the extension section 21 are connected via a plurality of second bolts 25 .

[0052] The adjustment plate 24 is fixedly connected to the upper end of the limit plate 22 in an inverted L shape, and the adjustment plate 24 is connected to the extension section 21 by a second bolt 25. The distance between the adjustment plate 24 and the extension section 21 is adjustable so that the distance between the upper positioning plate 18 and the lower positioning plate 19 can be flexibly adjusted according to the thickness of the flip platform plate 3, and the applicability is strong.

[0053] Specifically, combined Figure 5 and Figure 6 As shown, the locking structure 4 includes a sliding groove 26 arranged on one end of the flip platform plate 3 near the flip locking frame 2, and a sliding block 27 is slidably connected in the sliding groove 26 along the length direction of the flip platform plate 3. The bottom end of the sliding groove 26 passes through the flip platform plate 3 and is provided with a guide groove 28 along the length direction of the flip platform plate 3. The bottom end of the sliding block 27 is provided with a synchronization rod 29 passing through the guide groove 28. A locking hole 30 is provided on the side of the flip locking frame 2 near the flip platform plate 3. A locking block 31 matching the locking hole 30 is provided on the side of the synchronization rod 29 near the flip locking frame 2, and a flip cover 32 is provided at the top of the sliding groove 26.

[0054] The flip cover 32 at the top of the sliding groove 26 is used to open and close the sliding groove 26. When the flip platform plate 3 needs to be locked on the flip locking frame 2, the sliding block 27 is slid toward the flip locking frame 2, and the synchronization rod 29 at the bottom end of the sliding block 27 slides synchronously in the guide sliding groove 28. After the locking block 31 on the synchronization rod 29 enters the locking hole 30 on the side of the flip platform plate 3, the opening and closing locking position of the flip platform plate 3 is fixed. When unlocking is required, the sliding block 27 is slid in the opposite direction to move the locking block 31 on the synchronization rod 29 out of the locking hole 30.

[0055] Specifically, combined Figure 5 and Figure 6 As shown, a limiting structure 33 is provided between the sliding block 27 and the sliding groove 26 to prevent the sliding block 27 from shifting when the locking block 31 cooperates with the locking hole 30. The limiting structure 33 includes a limiting rod 34 hinged at the junction of the side of the sliding block 27 away from the flip locking frame 2 and the top of the sliding block 27, and a limiting groove 35 that cooperates with the limiting rod 34 is provided on the inner side wall of the sliding groove 26.

[0056] When the locking block 31 on the synchronization rod 29 enters the locking hole 30 to realize the opening and closing locking and fixing of the flip platform plate 3, the flip limit rod 34 makes the limit rod 34 abut against the limit groove 35 of the sliding groove 26 to prevent the sliding block 27 from shifting, ensuring that the locking block 31 will not accidentally fall out of the locking hole 30, thereby ensuring the locking and fixing effect of the flip platform plate 3. When the limit rod 34 is not in use, it is flipped to abut against the upper end of the sliding block 27.

[0057] The working principle of the utility model is as follows: when it is necessary to maintain and repair the switch machine installed in the broken part of the roadbed concrete surface, the flip cover 32 is flipped up, and the sliding block 27 is first slid a short distance toward the flip locking frame 2 to disengage the limit rod 34 from the sliding groove 26, and then the sliding block 27 is slid toward the flip connecting frame 1 to disengage the locking block 31 from the locking hole 30 to complete the unlocking of the flip platform plate 3, and the flip platform plate 3 can be flipped up for maintenance and repair;

[0058] When the flipping platform plate 3 flips, it rotates around the hinged connection shaft 15 located at the top outer side of the flipping platform plate 3 to avoid interference with the adjacent fixed platform plate 5. The gap between the flipping platform plate 3 and the adjacent fixed platform plate 5 is very small, and there is no need to set up an additional cover plate to block the gap; after the support plates 10 on both sides of the bottom end of the flip connecting frame 1 and the flip locking frame 2 are fixedly installed, the pipeline avoidance area 8 between the two support plates 10 plays a role of giving way to the pipelines on the concrete surface of the roadbed, which can prevent interference with the pipelines and affect the installation.
