Description

Technical Field

[0001] The invention belongs to the field of subway rescue, and in particular relates to a U-shaped beam rescue crossing board in an elevated section of a subway. Background Art

[0002] Shanghai Metro Line 16 is the first line in Shanghai to use the third rail for power supply. Unlike other subway trains, it is not equipped with a safety evacuation ladder at the front of the train due to the third rail for power supply. Therefore, the evacuation method of connecting trains on adjacent lines is currently adopted to evacuate passengers on the subway trains that are forced to stop in the section as soon as possible. When a rail transit train that uses the third rail for power supply stops between two platforms due to a fault, the process of evacuating passengers is as follows: the train dispatcher directs the adjacent line rescue train to run to a position parallel to the faulty train and stop. The driver will guide all passengers from the faulty train to the maintenance platform between the two car passenger compartment doors, and then transfer them to the rescue train. The rescue train runs back to the station to evacuate passengers.

[0003] Since passengers need to be transferred from the faulty train to the rescue train, there are the following risks in the process of transferring and evacuating passengers: (1) Since the maintenance platform is a U-beam structure, there is a gap between it and the train and the train floor plane is higher than the maintenance platform, there is a risk of passengers falling off the line when moving from the faulty train to the maintenance platform and from the maintenance platform to the rescue vehicle. (2) There is a gap in the middle of the maintenance platform, and there is a risk of passengers tripping and falling off the line when evacuating. (3) During the evacuation process, the two trains open the first door to transfer passengers, and there is a collector shoe (third rail) installed underneath. Passengers who fall off the line through the gap are at risk of electric shock. (4) There is a problem that it is difficult for the elderly, weak, sick, disabled, pregnant, and other passengers to be evacuated through the maintenance platform. Summary of the invention

[0004] In order to solve the risk problem existing in evacuating passengers, the present invention provides a U-beam rescue bridge for elevated sections of subways.

[0024] The present invention provides a U-shaped beam rescue crossing board in a subway elevated section, which is used to connect a rescue train and a faulty train, so that passengers in the faulty train can transfer to the rescue train through the U-shaped beam rescue crossing board. Figure 1 to Figure 4 As shown, the U-beam rescue ferry includes: two box components of the same shape, such as Figure 1 and Figure 3As shown, each of the box components includes: a box 1, which is welded by four patterned aluminum plate side panels and one patterned aluminum plate top panel, and has a hollow inner cavity; mounting holes 3, respectively opened at the four corners of the patterned aluminum plate top panel of the box 1; four support mechanisms, fixedly welded to the four corners of the inner cavity of the box 1; two armrest mechanisms, connected to the support mechanisms through the mounting holes 3; a flap 6, which is hingedly connected to the bottom end of one of the side panels of the box 1 through a plurality of second hinges 22, so that the flap 6 can be flipped around the second hinge 22 to form two states of the flap being opened (in use state, the flap 6 and the top panel of the box 1 are in the same plane) or folded (in storage state when not in use, the flap 6 covers the top panel of the box 1); a plurality of inner lining aluminum square tubes 7, which are respectively fixedly welded to the top panel and side panels of the box 1 in a grid shape, and are located in the inner cavity of the box 1, and are used to support the box to improve stability.

[0025] Furthermore, the two box assemblies are hingedly connected by a plurality of first hinges 21, so that any box assembly can be flipped around the first hinge 21, and then the two opened box assemblies (in use state) are closed to form a closed cavity (in storage state when not in use). Specifically, the top ends of the side panels of the two boxes 1 opposite to the side connected to the flap 6 are hingedly connected by a plurality of first hinges 21.

[0026] Among them, Figure 2As shown, each of the armrest mechanisms includes: a first armrest retaining tube 8, which is formed by welding three first hollow retaining tubes 801 that are parallel to each other and spaced apart and two first columns 802 that are perpendicular to the first hollow retaining tubes 801 (specifically, each first column 802 is respectively connected to the same end of the three first hollow retaining tubes 801 by welding), one end of the first hollow retaining tube 801 is provided with an opening, and the end of each of the first hollow retaining tubes 801 that is provided with an opening is penetrated and welded to the same first column 802, that is, the side wall of the first column 802 is provided with an opening that is connected to the first hollow retaining tube 801, and the lower end of the first column 802 is also provided with an opening for connecting with the supporting mechanism; an embedded spring pin 10 is arranged inside any first hollow retaining tube 801 of the first armrest retaining tube 8; a second armrest retaining tube 9, which is formed by welding two second hollow retaining tubes 901 that are parallel to each other and spaced apart and a second column 902 that is perpendicular to the second hollow retaining tube 901. (Specifically, the second column 902 is respectively connected to the same end of the two second hollow retaining tubes 901 by welding), and the diameter of the second hollow retaining tube 901 is smaller than the diameter of the first hollow retaining tube 801, so that the second hollow retaining tube 901 can be inserted into the corresponding first hollow retaining tube 801 from the opening of the first hollow retaining tube 801; at the same time, a card slot 903 is provided on the outer wall of the second hollow retaining tube 901, and the second hollow retaining tube 901 where the card slot 903 is located corresponds to the first hollow retaining tube 801 where the embedded spring pin 10 is located; when the second hollow retaining tube 901 is inserted into the first hollow retaining tube 801, the embedded spring pin 10 is contracted by the pressure of the second hollow retaining tube 901, and when the embedded spring pin 10 is aligned with the card slot 903, the embedded spring pin 10 automatically pops out and locks with the card slot 903, fixing the first handrail retaining tube 8 and the second handrail retaining tube 9, avoiding lateral displacement and falling off of the second handrail retaining tube 9, and at the same time extending the length of the handrail mechanism.

[0027] Among them, Figure 4 As shown, each support mechanism includes: a support plate 12, which is fixedly connected to the inner lining aluminum square tube 7 at the four corners of the inner cavity of the box body 1 through a welding process; a cylindrical support 11, whose top end is a conical guide, and the bottom end is welded and fixed to the top surface of the support plate 12; the two first columns 802 of the first handrail retaining tube 8 can accurately cover the two cylindrical supports 11 at the corners of the two ends of the side plate adjacent to the side connected to the flap 6 through the mounting hole 3 and the conical guide, so that the handrail mechanism and the support mechanism are connected (such as Figure 1 shown).

[0028] Among them, Figure 1 As shown, each of the box components further includes: two moving rollers 4, which are fixedly arranged at both ends of one side plate of the box 1 (in this embodiment, as shown in FIG. Figure 1As shown, a side panel with two movable rollers 4 is arranged opposite to a side panel with a handrail mechanism installed); a handle 5 is fixedly arranged on a side panel of the box body 1 opposite to the side panel with the movable rollers 4; through the arrangement of the movable rollers 4 and the handle 5, it is convenient to transport the U-beam rescue ferry to the rescue site.

[0029] Among them, Figure 4 As shown, a lock 13 is provided between the side panels of the two box assemblies that are not connected by the first hinge 21, and a lock 13 is also provided between the flap 6 and the side panel of the box 1, which plays a fixing role when the two boxes 1 are closed (for transporting the box 1) and when the flap 6 is in a folded state.

[0030] Among them, Figure 2 As shown, when the flap 6 is in the open state, its top end is a slope structure with a certain angle slope, so that when the flap 6 is in the open state, the step difference at the connection between the flap 6 and the carriages of the rescue train and the faulty train is reduced, making it difficult for the elderly and children to trip and easier for wheelchairs and trolley cases to pass smoothly.

[0031] The first hinge 21 and the second hinge 22 are fixedly connected to the box body 1 and the flap 6 respectively by using rivets.

[0032] Among them, the first handrail stop tube 8 and the second handrail stop tube 9 are fixedly stored in the inner cavity of the box 1 when not in use; at the same time, ropes and cloth-based tapes are also configured in the inner cavity of the box 1, and the ropes include 2 nylon ropes, which are used to bind the handrails of the rescue train, the handrail mechanism of the rescue ferry and the handrail of the faulty train to prevent the movement of the U-beam rescue ferry; the cloth-based tape is used to fix the rope on the second handrail stop tube 9 to prevent the rope from sliding up and down on the second column 902.

[0033] It should be noted that when the U-beam rescue ferry is not in use, the U-beam rescue ferry is first in an upright state, at which time the flap 6 is in a folded state, the two box assemblies are in a closed state, and the lock 13 is in a locked state for fixation; when it is needed, first keep the U-beam rescue ferry in the current upright state, and move the U-beam rescue ferry to the rescue site through the handle 5 and the moving roller 4. Then open the lock 13, and then flip the box assembly to open it, take out the handrail mechanism stored in the inner cavity of the box 1, and connect the first handrail retaining tube 8 and the second handrail retaining tube 9 in the handrail mechanism through the embedded spring pin 10; further, as Figure 5As shown, the box assembly in the open state is placed flat on the maintenance platform D (U-beam structure), and the two flaps 6 are further flipped to open, and connected to the rescue train A and the faulty train B respectively, so that the two trains are connected through the box assembly, and then the handrail mechanism is inserted into the mounting hole 3 and connected to the support mechanism. Finally, the rescue board C is fixed with ropes and cloth-based tape, so that the passengers are transferred to the rescue train in turn to complete the safe evacuation.

[0034] In summary, compared with the existing subway rescue devices, the subway elevated section U-beam rescue board device provided by the present invention has the advantages of easy use, fast passenger evacuation, and high stability.
