Technical Field

[0001] The invention relates to the technical field of turnout area evacuation platforms, in particular to a continuous transition device for a turnout area evacuation platform of a guide rail type rubber wheel system. Background Art

[0002] The rail-type rubber-tyred system is a form of low-capacity rail transit, and is also a standard that has been promoted in recent years. The rail-type rubber-tyred system adopts an integrated design of steel beams and tracks, and is arranged in the form of viaducts. The track beam also functions as an evacuation channel. When the equipment fails and the train stops in the section, passengers can evacuate through the evacuation platform inside the track beam to reach the nearby station.

[0003] The inventors found that due to the existence of the switch mechanism in the switch area, the evacuation platform is discontinuous. When the equipment fails and the railway stops in the switch area, passengers need to cross the track beams and evacuate from the outside of the switch. This method has the problem of chaotic evacuation paths in the switch area. Since the track beams are laid on an elevated structure and the switch is generally 10-15m from the ground, there are high safety risks when passengers pass from the outside.

[0030] like Figure 3 As shown, the track beam includes a first track beam 20 and a second track beam 21. A switch area is provided between the first track beam 20 and the second track beam 21. The switch area is provided with a switch platform 11. The switch platform 11 is provided with a switch mechanism. The track beams are connected to each other through the switch mechanism. It can be understood that, as Figure 1 As shown, a side track beam is also provided on the side of the second track beam 21. This embodiment takes into account the two operating conditions of the turnout, the turnout straight opening and the turnout lateral opening, and the evacuation platform continuous transition device can meet the use requirements. Among them, the turnout straight opening is A→B, and the turnout lateral opening is A→C.

[0031] It should be noted that Figure 1 Taking the viewing direction as an example, the left side of the figure is the head end of the turnout, and the right side is the tail end of the turnout.

[0032] The bottom of the track beam is provided with an evacuation platform, which is a prior art, wherein, Figure 1 As shown in Figure 3, a head end evacuation platform 1 is provided at the bottom of the first track beam 20, a vertical evacuation platform 10 is provided at the bottom of the second track beam, and a lateral evacuation platform 9 is provided at the bottom of the side track beam. The evacuation platforms are all located at the end positions of the track beams close to the switch area.

[0033] A turnout platform 11 is provided in the turnout area, and both ends of the turnout platform 11 are connected between the bridge pedestal 15 on the left and the bridge pedestal 16 on the right, and the top surface of the turnout platform 11 is flush with the top surface of the bridge pedestal. The end of the track beam is supported on the bridge pedestal. The turnout area includes the bridge pedestals 15, 16 and the turnout platform 11, and a guardrail 19 is provided around the entire turnout area to meet safety requirements; of course, the bridge pedestals 15, 16 and the turnout platform 11 can be used together as a turnout platform, that is, the bridge pedestal in the turnout area is also a part of the turnout platform, and the turnout platform 11 also serves as a maintenance platform.

[0034] The switch mechanism 18 includes a transmission link 12 and a transmission link 13 provided above the middle position of the switch platform. The transmission link 12 and the transmission link 13 have the same height and are arranged in a vertical direction. The transmission link 12 and the transmission link 13 have a set spacing. The transmission link 12 and the transmission link 13 can realize the track changing of the switch movable rail in the switch area. The transmission link 12 can play a supporting role during the sliding process of the switch movable rail. The switch mechanism is a prior art.

[0035] like Figure 2 As described, a turnout head end downward staircase 2 is provided on the bridge pedestal 15 at the head end of the turnout area, and a turnout tail end straight upward staircase 6 and a turnout tail end side upward staircase 8 are provided on the bridge pedestal 16 at the tail end of the turnout area.

[0036] Specifically, the downward step 2 at the head end of the turnout is fixedly docked at the head end evacuation platform 1 of the first track beam 20. Its top end is flush with the head end evacuation platform 1, does not exceed the driving limit, and does not affect driving. Its bottom end is fixedly connected to the bridge pedestal 15 (top surface of the turnout platform) by fixing bolts 17.

[0037] An emergency evacuation door is provided at the head of the vehicle. Under special conditions, passengers can reach the evacuation platform from the emergency evacuation door. Through the downward stairs 2 at the head end of the turnout, the passengers can move from the head end evacuation platform 1 to the bridge pier 15 via the downward stairs 2 at the head end of the turnout, thereby achieving the purpose of initial movement to the turnout platform 11.

[0038] The straight upward step ladder 6 at the tail end of the turnout is fixedly docked at the straight evacuation platform 10 of the second track beam 21. Its top end is flush with the straight evacuation platform 10, does not exceed the driving limit, and does not affect driving. Its bottom end is fixedly connected to the bridge pedestal 16 by fixing bolts 17.

[0039] The upward step 8 at the tail end of the turnout is fixedly docked at the lateral evacuation platform 9 of the lateral track beam at the tail end. Its top end is flush with the lateral evacuation platform 9, does not exceed the driving limit, and does not affect driving. Its bottom end is fixedly connected to the bridge pedestal 16 by fixing bolts 17.

[0040] This embodiment realizes a continuous transition from the evacuation platform of the track beam to the turnout platform by providing a downward step 2 at the turnout head end, a straight upward step 6 at the turnout tail end, and a side upward step 8 at the turnout tail end. Two groups of upward steps at the turnout tail end are provided, one group meets the need for straight evacuation of the turnout through the straight upward step 6 at the turnout tail end, and one group meets the need for lateral evacuation of the turnout through the side upward step 8 at the turnout tail end.

[0041] The downward stairs at the turnout head end and the upward stairs at the turnout tail end of the present embodiment are both fixedly arranged.

[0042] like Figure 2As shown, since the turnout mechanism in the middle of the turnout platform includes a transmission link 12 and a transmission link 13, the transmission link 12 is located on the left side of the transmission link 13, and the two have a set height, the passengers need to cross the transmission link 12 and the transmission link 13 after reaching the turnout platform 11. Therefore, this embodiment sets a middle turnout step and a middle turnout transition platform to enable passengers to cross the transmission connection.

[0043] like Figure 1 and Figure 2 As shown, specifically, the middle step of the turnout includes an upward step 3 and a downward step 3 arranged on both sides of the transmission connecting rod, and a middle transition platform 4 of the turnout. The middle transition platform of the turnout is located between the transmission connecting rod 12 and the transmission connecting rod 13, and the height of the middle transition platform of the turnout is adapted to the height of the transmission connecting rod.

[0044] The middle transition platform 4 of the turnout is also located between the middle upward staircase 3 of the turnout and the middle downward staircase of the turnout, wherein the middle upward staircase 3 of the turnout is located on the left side of the transmission connecting rod 12, which is located in the straight track direction. The middle downward staircase of the turnout is located on the right side of the transmission connecting rod 13, and the height of the middle staircase of the turnout is adapted to the height of the transmission connecting rod.

[0045] The passenger can pass through the transmission connecting rod 12, the transition platform 4 and the transmission connecting rod 13 in sequence via the upward step 3 in the middle of the turnout, and then return to the turnout platform via the downward step in the middle of the turnout, so as to achieve the purpose of crossing the transmission connecting rod in sequence.

[0046] like Figure 1 As shown, the transmission connecting rod 13 has a set length, and two groups of the middle downward stairs of the turnout need to be provided, one group is the middle straight downward stairs 5 of the turnout, and the other group is the middle side downward stairs 7 of the turnout arranged on one side of the middle straight downward stairs 5 of the turnout. The top ends of the middle straight downward stairs 5 of the turnout and the middle side downward stairs 7 of the turnout are both connected to the transmission connecting rod 13. The middle stairs of the turnout are supported by the turnout platform 11.

[0047] The straight downward stairs 5 in the middle of the turnout are located in the vertical track direction, while the lateral downward stairs 7 in the middle of the turnout are located in the lateral track direction. The straight downward stairs 5 in the middle of the turnout meet the vertical evacuation needs of the turnout, and the lateral downward stairs 7 in the middle of the turnout meet the lateral evacuation needs of the turnout.

[0048] The upward staircase 3 in the middle of the turnout, the straight downward staircase 5 in the middle of the turnout, and the lateral downward staircase 7 in the middle of the turnout in this embodiment are not fixedly arranged but movable so as to make room for maintenance during maintenance.

[0049] During the evacuation process, passengers can walk forward along the interval evacuation platform without turning outward to the outside of the track beam in the turnout area, and there is no related risk. The added stairs do not intrude into the driving limit, which is safe and reliable. At the same time, it can compress the turnout platform space, shorten the area width, and reduce the project investment.

[0050] like Figure 1-Figure 3 As shown, the continuous transition device of the evacuation platform in the turnout area of ​​the rail-type rubber-tyred system is divided into two evacuation states. One state is that the turnout is opened in a straight direction (i.e., the AB direction is opened). During the evacuation process, the passengers reach the turnout area from the evacuation platform 1 at the head end of the section track beam, pass the descending stairs 2 at the head end of the turnout, reach the ascending stairs 3 in the middle of the turnout, then cross the transmission connecting rod 12 to reach the transition platform 4 in the middle of the turnout, then cross the transmission connection 13, return to the top surface of the turnout platform 11 through the descending stairs 5 in the middle of the turnout, and then go straight up the stairs 6 at the tail end of the turnout to reach the straight evacuation platform 10, and finally reach the nearby station to complete the evacuation.

[0051] Another state is that the turnout is opened laterally (i.e., the AB direction is opened). During the evacuation process, passengers reach the turnout area from the evacuation platform 1 at the head end of the section track beam, pass the downward stairs 2 at the head end of the turnout, reach the upward stairs 3 in the middle of the turnout, then cross the transmission connecting rod 12 to reach the transition platform 4 in the middle of the turnout, then cross the transmission connection 13, pass the downward stairs 7 at the middle side of the turnout, return to the top surface of the turnout platform 11, and then pass the upward stairs 8 at the tail end side of the turnout to reach the lateral evacuation platform 9, and finally reach the nearby station to complete the evacuation.

[0052] It is understandable that the above evacuation path can also be implemented in reverse.

[0053] By setting corresponding steps and transition platforms on the turnout platform, a continuous transition between the turnout platform and the evacuation platform can be achieved. Passengers do not need to flip out to the outside of the track beam during evacuation, reducing safety hazards.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
