Description

TECHNICAL FIELD

[0001] The present application relates to the field of train technology, in particular, to a train through passage folding shed device. BACKGROUND

[0002] The through passage is a flexible connecting component between the carriages of a subway train, which has the functions of waterproofing, windproofing, dustproofing and sound insulation, and provides a safe passage for passengers and adapts to train turning and slope changes.

[0003] Generally, the through passage is composed of a folding shed, a top plate, a guard plate and a step plate. The folding shed includes two installation frames arranged at intervals, and a shed cloth assembly is further arranged between the two installation frames. The shed cloth assembly specifically includes a plurality of clamping cloth frames arranged at intervals, and the shed cloth is clamped between two adjacent clamping cloth frames in a bent posture. When the train turns, the shed cloth will correspondingly stretch and contract to adapt and maintain the stability of the passage.

[0004] Although the bottom of the folding shed will be partially in contact with the coupler wear plate, thereby providing the folding shed with a vertical support force, the remaining area of the folding shed will still have insufficient support, resulting in reduced reliability of the through passage. SUMMARY

[0005] The present application aims to overcome the shortcomings of the prior art and provide a train through passage folding shed device.

[0013] Preferably, the sealing member is adapted to drive the cloth to be concave downward at the drainage hole by gravity.

[0014] Preferably, the sealing member comprises a sliding shaft, the bottom of the sliding shaft is provided with a sealing piece, the top of the sliding shaft is provided with a pressing plate, the size of the sealing piece is greater than that of the drainage hole, the size of the pressing plate in at least one direction is greater than that of the drainage hole, and the size of the pressing plate in at least one direction is smaller than that of the drainage hole.

[0015] Preferably, the sealing member comprises a mounting seat adapted to the drainage hole, and a pressing block attached to the driving rope, the mounting seat is provided with a water outlet, and a sealing shaft is elastically arranged in the water outlet in the vertical direction; only when the two connecting ropes are in the relaxed state at the same time, the pressing block presses downward in the vertical direction and pushes the sealing shaft to open the water outlet.

[0016] The beneficial effects of the present application are: 1. The connecting rope is tied between the two mounting frames, and the connecting rope passes through the connecting hole on each cloth clamping frame, so that the relative position of the cloth clamping frame in the vertical direction can be limited by the connecting rope.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, a train passageway folding canopy device includes two mounting frames 1 located at both ends. The folding canopy is connected between two car bodies by fastening the two mounting frames 1 to the two car bodies. A canopy assembly 2 is specifically disposed between the two mounting frames 1, and the canopy assembly 2 includes several spaced-apart fabric clamping frames 3. Similar to existing technology, a canopy 4 is clamped between adjacent fabric clamping frames 3. The canopy 4 is typically made of a flexible material, such as silicone or rubber. When the train turns, one side of the canopy 4 is compressed while the other side is stretched, thereby maintaining the stability of the passageway.

[0022] To improve the vertical support reliability of the folding canopy, each fabric clamping frame 3 is fitted with a connecting hole 5, and a connecting channel 6 is formed between the corresponding connecting holes 5. A connecting rope 7 passing through the connecting channel 6 is tied between the two mounting frames 1. Since the mounting frames 1 are fastened to the vehicle body, the connecting rope 7 is equivalent to being tied between the two vehicle bodies, which keeps the connecting rope 7 in a relatively stable vertical position. With the connection of the connecting rope 7 and the connecting hole 5, the connecting rope 7 can resist the possible downward tendency of the fabric clamping frame 3, so that the folding canopy can receive auxiliary support in the vertical direction, and the stability of the through channel between adjacent vehicle bodies is also improved accordingly.

[0023] In some embodiments, the fabric clamping frame 3 preferably includes a main body 8 and clamping plates 9 disposed on both sides of the main body 8, in which case the fabric clamping frame 3 can clamp the drape 4 on both the inner and outer sides. According to the radial arrangement, the two drapes 4 can be defined as the inner drape 4 and the outer drape 4. A relatively sealed cavity will be formed between the inner drape 4 and the outer drape 4, which improves the sound insulation and heat insulation performance of the folding awning.

[0024] For example, the inner and outer layers of the canopy 4 can be arranged in a wave-like manner, which makes the cavity appear capsule-shaped in cross-section, thus providing better sound insulation and heat insulation effects. The connecting hole 5 can preferably be opened on the main body 8, which will also help maintain the integrity of the canopy 4 without constructing an opening on the canopy 4 to accommodate the passage of the connecting rope 7.

[0025] like Figure 4 As shown, in some other embodiments, a drainage hole 10 may also be provided at the bottom of the canopy 4. When water accumulates inside the canopy 4, the water can be drained through the drainage hole 10. In one example, an arc-shaped groove (not shown) may be cut at the bottom of the canopy 4. In this case, a connecting ear that can be folded outward can be formed at the arc-shaped groove of the canopy 4, that is, the opening of the canopy 4 at the connecting ear constitutes the aforementioned drainage hole 10. Although the connecting ear can block external dust from entering the canopy 4 to a certain extent, the airtightness of the canopy 4 is compromised, resulting in a reduction in sound insulation and heat insulation performance.

[0026] Alternatively, a sealing element 11 can be fitted inside the drain hole 10, allowing the drain hole 10 to be selectively opened or closed. This allows the drain hole 10 to be covered by the sealing element 11 to maintain the airtightness of the capsule cavity when the canopy 4 does not require drainage; conversely, when water accumulates in the canopy 4, the drain hole 10 can be opened by the sealing element 11, allowing the water to drain out without causing corrosion to the canopy 4 or the fabric frame 3.

[0027] like Figure 3 As shown, in a preferred example, connecting holes 5 are provided on the connecting arms on both sides of the fabric clamping frame 3, that is, connecting channels 6 are constructed on both sides of the fabric clamping frame 3, and a connecting rope 7 is threaded through each connecting channel 6. A driving rope 12 is also connected between the two connecting ropes 7. The driving rope 12 is arranged along the direction of the capsule cavity, and from the cross-section, the driving rope 12 can be U-shaped or V-shaped. The sealing member 11 is preferably adapted and attached to the driving rope 12.

[0028] In addition, a winding device 13 is provided on the mounting frame 1. For example, the winding device 13 may include a motor and a winding roller on the output shaft of the motor, and the end of the corresponding connecting rope 7 is wound around the winding roller. It can be understood that as the motor rotates forward or reverse, the connecting rope 7 will switch between a tensioned state and a slack state. In the tensioned state, the sealing member 11 is lifted upward, and the drain hole 10 remains closed; while in the slack state, the sealing member 11 will move downward under the action of gravity, thereby opening the drain hole 10.

[0029] In a preferred embodiment, the sealing element 11 is also adapted to have a certain weight. Thus, when the connecting rope 7 is in a slack state, the sealing element 11 will press down on the canopy 4 under its own weight, causing the canopy 4 to indent at the drainage hole 10. At this time, the water accumulated inside the canopy 4 will more easily flow from high to low towards the drainage hole 10 and be discharged from the drainage hole 10, ultimately achieving the effect that water is less likely to remain inside the canopy 4. Furthermore, since the drive rope 12 is connected to the connecting rope 7, the weight of the sealing element 11 is actually borne by the connecting rope 7 and the mounting frame 1, and is less likely to cause additional stress on the folding canopy.

[0030] like Figure 4 , Figure 5 As shown, in some embodiments, the sealing member 11 may include a sliding shaft 14, with a pressure plate 16 at its top and a sealing piece 15 at its bottom. The pressure plate 16 has a dimension larger than the drain hole 10 in at least one direction, and a dimension smaller than the drain hole 10 in at least one direction; for example, the pressure plate 16 may be elongated. The sealing piece 15 is adapted to be larger than the drain hole 10. It is understood that when the connecting rope 7 is taut, the sliding shaft 14 is lifted upwards, and the sealing piece 15 covers the drain hole 10. When the connecting rope 7 is slack, the sliding shaft 14 moves downwards, and the pressure plate 16 presses down on the tarpaulin 4, causing it to indent. Since the pressure plate 16 is smaller than the drain hole 10, moisture inside the tarpaulin 4 will drain out through the gap between the pressure plate 16 and the drain hole 10.

[0031] In this example, an angle sensor (not shown) can preferably be installed on the vehicle body or the canopy, and the angle sensor can be electrically connected to the motor. When the angle sensor detects that the train is turning, the direction of the train and the turning angle can be determined based on the detected angle. For example, this can be used to control the winding of the connecting rope 7 corresponding to the compression side of the canopy 4, so that the connecting rope 7 can always be kept taut and is not prone to becoming slack due to the turning of the train. As a result, the sealing member 11 is less likely to unintentionally open the drain hole 10.

[0032] like Figure 6 As shown, in other configurations, the sealing element 11 may include a mounting base 17 disposed within the drain hole 10, and a pressure block 18 attached to the drive rope 12. The mounting base 17 is specifically provided with a water outlet 19, and a sealing shaft 20 is vertically spring-loaded within the water outlet 19. In its natural state, the sealing shaft 20 can maintain a tight seal on the water outlet 19, thereby ensuring the airtightness of the canopy 4. When water accumulates inside the canopy 4, the two winding devices 13 can be controlled to simultaneously extend the two connecting ropes 7, that is, the two connecting ropes 7 will simultaneously enter a slack state. Subsequently, the pressure block 18 will press vertically downwards and push the sealing shaft 20 to open the water outlet 19, allowing the accumulated water to drain through the water outlet 19.

[0033] When the train turns, although the connecting rope 7 corresponding to the compression side of the canopy 4 will also briefly enter a slack state, the connecting rope 7 corresponding to the tension side of the canopy 4 will still remain taut. At this time, the downward movement of the pressure block 18 will tilt towards the compression side of the canopy 4, rather than pressing down vertically as described above. Finally, the pressure block 18 will be misaligned with the sealing shaft 20, and the sealing shaft 20 will still maintain a sealed state against the outlet 19.

[0034] In a preferred embodiment, the top of the mounting base 17 has a mating hole, and the sealing shaft 20 and the outlet 19 are constructed at the inner end face of the mating hole. If the pressure block 18 moves downward in an inclined position, it will be stopped at the top of the mounting base 17 and will not easily press down on the sealing shaft 20 because it cannot properly engage in the mating hole. Conversely, if the pressure block 18 is pressed vertically downward, it will smoothly engage in the mating hole and push the sealing shaft 20 downward.

[0035] For example, an air pump 21 can be provided at the inner end face of the joint hole. The specific structure of the air pump 21 can be set with reference to the air pump in the prior art. The air pump rod of the air pump 21 extends into the joint hole, and the length of the air pump rod of the air pump 21 is adapted to be greater than the length of the sealing shaft 20. In this way, as the pressure block 18 is pressed down, the pressure block 18 will press the air pump rod first, so that the air pump 21 pumps the external air into the tarpaulin 4.

[0036] The present invention may have the following exemplary operating process: The first type: No water accumulation appears on the tarpaulin 4. The winding device 13 can be controlled to loosen the connecting rope 7 with a small extension. At this time, the pressure block 18 will only press the air pump 21 and will not press down the sealing shaft 20. That is, the air pump 21 can pump air into the tarpaulin 4, thereby improving the heat insulation and sound insulation performance of the tarpaulin 4, while the sealing shaft 20 remains sealed to the water outlet 19. For example, the air pump 21 can be pumped into the tarpaulin 4 multiple times by controlling the winding device 13 to alternate between winding and unfolding, so as to maximize the amount of air in the tarpaulin 4.

[0037] The second type: When water accumulates inside the canopy 4, the winding device 13 can be controlled to rotate out a larger amount, causing the connecting rope 7 to enter a slack state. At this time, the pressure block 18 will first press the air inflator 21, and then press down the sealing shaft 20. For the cavity inside the canopy 4, the air pressure inside can be increased by the air inflator 21, and then the sealing shaft 20 will open the water outlet 19. Under the action of air pressure, the accumulated water can be discharged from the water outlet 19 more quickly.

[0038] The output end of the air inflator 21 can be connected to the internal cavity of the tarpaulin 4 through a pipe, so that when the air inflator 21 is pressed, external air can enter the tarpaulin 4 through the pipe.

[0039] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
