Rail vehicle evacuation device and rail vehicle

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application with application number 2023115617179 filed with the Chinese Patent Office on November 22, 2023, entitled “A Rail Vehicle Evacuation Device and Rail Vehicle,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of rail transportation technology, and in particular to a rail vehicle evacuation device and a rail vehicle. Background Art

[0004] In order to ensure the safety of passengers when a rail vehicle encounters an accident and cannot continue to operate, rail transit vehicles are equipped with evacuation ladders that can be manually or automatically retracted and folded for safe and efficient evacuation of passengers in an emergency.

[0005] Existing emergency evacuation ladders, when deployed, extend perpendicularly to the vehicle, along the direction of the vehicle door. The extended ladder is extremely wide, taking up a lot of space. Furthermore, the ladder's structure is complex, and automatic extension and retraction requires the activation of several cylinders, making extension time-consuming. For example, one existing rail vehicle has an evacuation ladder installed at the escape door. The skirt panels on both sides of the vehicle are typically fixed. For side evacuations, the skirt panels must be opened before the ladder can be deployed, making it inconvenient and time-consuming, delaying evacuation.

[0006] In addition, the terrain conditions in which trains are in emergency situations are different, and the height of the train floor from the ground is different, so the height of the required evacuation ladder is uncertain. For example, some heights are high and five steps need to be unfolded, while some heights are low and only four steps need to be unfolded. The existing emergency evacuation ladders have poor adaptability to different heights.

[0007] For example, a prior art side evacuation ladder for rail transit vehicles and its control method, in which the ladder can be retracted and stored in a storage box on the side of the vehicle, can be opened and retracted step by step according to the platform's needs. While the patent allows for adjustment of the number of steps the ladder can extend according to the installation height, the height of each step is fixed, making fine-tuning to achieve the optimal height difficult. Furthermore, the direction in which the steps extend and retract is perpendicular to the vehicle, requiring a high floor space requirement in the direction of extension. Furthermore, the number of steps required for folding and storage is large, taking up a large amount of space.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Example 1

[0047] The embodiment of the present application provides a rail vehicle evacuation device 100, and the rail vehicle evacuation device 100 is deployed on the side of the car as shown in Figure 1. The rail vehicle evacuation device 100 is shown in Figure 2 and includes: a fixed bracket 110, a telescopic drive mechanism 120, and a ramp body 130, wherein the fixed bracket 110 includes a fixed beam 111 and a storage box 112, wherein the fixed beam is fixed to the bottom surface of the car floor 200 below the car door, and the storage box 112 is fixed to the fixed beam 111, and a storage cavity 1120 is provided in the storage box 112, and the storage cavity 1120 is provided with an entrance and exit on the side facing the car door, and the side facing the car door refers to the direction perpendicular to the vehicle and the direction for passengers to get off the car. The ramp body 130 and the telescopic drive mechanism 120 are provided in the storage cavity 1120, and the entrance and exit are used for the ramp body 130 to be extended and retracted. The ramp body 130 includes a sliding base plate 131, a lifting mechanism 132, a pedal 133, a flip cylinder 134 and a telescopic ramp plate 136. The telescopic drive mechanism 120 is connected to the sliding base plate 131 of the ramp body 130, so that the ramp body 130 can be pushed out of the storage chamber 1120 and retracted into the storage chamber 1120. The lifting mechanism 132 lifts the pedal 133, and the flip cylinder 134 flips the telescopic ramp plate 136 to form an evacuation channel.

[0048] In this embodiment, the ramp body 130 is flipped parallel to the vehicle and then deployed. The width of the deployed rail vehicle evacuation device is the same as the width of the pedal 133, resulting in a narrow evacuation passage and minimal space. The folded lifting arm is stored in the lifting slot between the pedal 133 and the sliding base 131, significantly reducing the space occupied by the evacuation device. Furthermore, the lifting mechanism 132 provides greater stability and a stronger lifting force for the evacuation device.

[0049] As shown in Figure 3, the vehicle comprises a fixed bracket 110, which is fixed to the bottom surface of the vehicle floor. The fixed bracket 110 includes a fixing beam 111 and a storage box 112. The fixing beam 111 is bolted into a fixing groove on the bottom surface of the vehicle floor, firmly securing the storage box 112 to the bottom surface of the vehicle floor. The storage box 112 is provided with a storage cavity 1120, within which a ramp body 130 and a telescopic drive mechanism 120 are located. The telescopic drive mechanism 120 is capable of pushing the ramp body 130 out of the storage cavity 1120 and retracting it back into the storage cavity 1120.

[0050] As shown in Figures 4-5, the telescopic drive mechanism 120 includes a housing 121, within which a drive motor 122, such as a synchronous motor, is fixedly mounted. The output shaft of the drive motor 122 is connected to a reducer 123. The reducer 123 includes a first transmission gear at the motor output end and a second transmission gear meshing with the first transmission gear. The second transmission gear is fixed to a first rotating shaft 124 in a non-rotatable manner. Drive rollers 127 are fixedly mounted at both ends of the first rotating shaft 124. The first rotating shaft 124 and the second rotating shaft 125 are fixed to the housing 121. Drive rollers 127 are fixedly mounted at both ends of the second rotating shaft 125. A conveyor belt 126 is connected between the drive rollers 127 of the first rotating shaft 124 and the second rotating shaft 125. The driving motor 122 drives the first rotating shaft 124 through the reducer, the first rotating shaft 124 drives the transmission roller 127, 127 drives the conveyor belt 126, thereby driving the transmission rollers 127 at both ends of the second rotating shaft 125, so that the conveyor belt 126 rotates between the first rotating shaft 124 and the second rotating shaft 125.

[0051] A conveyor belt clamp 128 is fixed to the conveyor belt 126, and the top end of the conveyor belt clamp 128 is fixed to the bottom surface of the sliding base 131. As the conveyor belt 126 rotates with the first rotating shaft 124 and the second rotating shaft 125, it drives the conveyor belt clamp 128 to extend and retract, thereby driving the sliding base 131 to retract and retract relative to the storage box 112, allowing the ramp body 130 to retract and retract within the storage box 112. When the drive motor 122 rotates forward, the telescopic drive mechanism 120 drives the ramp body 130 to extend out of the storage box. When the drive motor 122 rotates reversely, the telescopic drive mechanism 120 drives the ramp body 130 to retract into the storage box.

[0052] In some embodiments, the conveyor belt 126 may also be a belt, a chain or a rack. When the conveyor belt is a chain or a rack, a gear ring that engages with the chain or the rack may be provided on the outside of the transmission roller 127 .

[0053] In some embodiments, a slide 1121 and a guide rail 1122 are symmetrically arranged in the storage box 112 of the fixed bracket 110, and the guide rail 1122 is arranged inside the slide 1121. A mounting block 1123 is also arranged inside the guide rail 1122 for fixing to the housing 121 of the telescopic drive mechanism 120, and the fixing method includes but is not limited to screw sleeve and bolt fixing.

[0054] As shown in Figure 6, the ramp body 130 includes a sliding base 131, a lifting mechanism 132, a tilting cylinder 134, a pedal 133, a retractable ramp plate 136, and a retracting mechanism 137. The skirt plate is fixed to the front end of the sliding base 131 of the ramp body 130. When the ramp body 130 is extended from the storage box 112 of the fixed bracket 110, the skirt plate extends along with the ramp body 130.

[0055] In this embodiment, the skirt panel 300 is fixedly connected to the sliding bottom plate 131. When the rail vehicle evacuation device is used, the skirt panel 300 and the sliding bottom plate 131 can move synchronously. There is no need to open the skirt panel first and then form an evacuation channel, nor is there a need to set up an additional skirt panel storage structure, which improves operational efficiency and simplifies the device structure.

[0056] Two rows of sliding rollers 1311 are provided on both sides of the sliding base 131. The sliding rollers 1311 cooperate with the slideway 1121 and slide on the slideway 1121. A sliding limiter 1312 is provided on the bottom surface of the sliding base 131. The sliding limiter 1312 cooperates with the guide rail 1122 and slides on the guide rail 1122. A first lifting groove 1313 is provided on the upper surface of the sliding base 131. The lifting mechanism 132 is disposed within the first lifting groove 1313. A first sliding groove 1314 is provided on the inner sidewall of the first lifting groove 1313, as shown in FIG8 .

[0057] As shown in Figure 9, the lifting mechanism 132 includes a first lifting arm 1321 and a second lifting arm 1322, which are hinged in the middle of a cross on one side, and a third lifting arm 1323 and a fourth lifting arm 1324, which are hinged in the middle of a cross on the other side. The hinge axis 1325 on both sides is the same. A connecting rod 1329 is also provided between the first lifting arm 1321 and the third lifting arm 1323, and between the second lifting arm 1322 and the fourth lifting arm 1324. These connecting rods 1329 are parallel to the hinge axis 1325 and are used to fix the distance between the hinged lifting arms on both sides, thereby improving the stability of the lifting mechanism.

[0058] The first and third lifting arms 1321 and 1323 are each fixed at one end to a second lifting slot 1331 on the bottom surface of the pedal 133, and a first pulley 1326 is fixed at the other end. The first pulley 1326 is movable within the first sliding slot 1314 of the sliding base 131. The second and fourth lifting arms 1322 and 1324 are each fixed at one end to the first lifting slot 1313, and a second end is fixedly connected to a second pulley 1327. The second pulley 1327 is movable within a second sliding slot 1332 defined or fixedly disposed on the inner sidewall of the second lifting slot 1331 on the bottom surface of the pedal 133. Two lifting cylinders 1328 are fixedly disposed within the first lifting slot 1313, located near the first pulley 1326. The other ends of the two lifting cylinders 1328 are fixedly connected to the hinge shaft 1325. The two lifting cylinders 1328 can give thrust to the articulated shaft 1325 to raise the lifting mechanism 132, and can give pulling force to the articulated shaft 1325 to lower the lifting mechanism 132.

[0059] When the lifting cylinder 1328 is pushed out, it pushes the hinge shaft 1325 to drive each lifting arm, causing the first pulley 1326 to slide from the first sliding groove 1314 to the fixed end near the second lifting arm 1322 and the fourth lifting arm 1324, and the second pulley 1327 to slide from the second sliding groove 1332 to the fixed end near the first lifting arm 1321 and the third lifting arm 1323, thereby raising the lifting mechanism 132. When the lifting cylinder 1328 is pulled back, it drives the hinge shaft 1325, causing the first pulley 1326 to slide from the first sliding groove 1314 to the fixed end away from the second lifting arm 1322 and the fourth lifting arm 1324, and the second pulley 1327 to slide from the second sliding groove 1332 to the fixed end away from the first lifting arm 1321 and the third lifting arm 1323, thereby raising the lifting mechanism 132.

[0060] The lifting height of the lifting mechanism 132 can also be adjusted according to the ground height, and has good terrain adaptability. After the height of the lifting mechanism is set, it can directly reach the predetermined height, thereby improving operational efficiency.

[0061] In some embodiments, the driving mechanism of the lifting mechanism 132 can also be driven by a winch 1340, a third pulley 1341, and a third steel wire rope 1342. As shown in FIG10 , the winch 1340 and the third pulley 1341 are disposed at opposite ends of the second lifting slot 1331 on the bottom surface of the pedal 133. One end of the third steel wire rope 1342 is led out from the winch 1340, and the other end passes through the third pulley 1341 and is fixed to a fixing post 1343 in the first lifting slot 1313. The third pulley 1341 is fixed to the side of the second lifting slot 1331 near the second chute 1332, and the fixing post 1343 is disposed in the first lifting slot 1313 near the first chute 1314. The winch 1340 drives the third steel wire rope 1342 to move the lifting mechanism up and down.

[0062] The pedal 133 and the telescopic ramp 136 are connected by a pivot shaft 1333. The telescopic ramp 136 can be folded over the pedal 133 before being deployed. A second accommodating groove 1335 and a third accommodating groove 1336 are provided on either side of the pedal 133. The second accommodating groove 1335 is located on the side of the pedal closer to the rail vehicle door, and the third accommodating groove 1336 is located on the side of the pedal farther from the rail vehicle door. A tilting cylinder 134 is fixedly mounted in each of the second and third accommodating grooves 1335 and 1336. One end of the tilting cylinder 134 is fixed to a cylinder seat 1337 within the second and third accommodating grooves 1335 and 1336, and the other end of the tilting cylinder 134 is movably connected to one end of a tilting link 135. The other end of the tilting link 135 is movably connected to the side of the telescopic ramp 136. The retractable ramp plate 136 is pushed by the turning cylinder 134 to rotate around the pivot shaft 1333 from being stacked on the pedal 133, so that the retractable ramp plate 136 contacts the ground, as shown in FIG. 7 .

[0063] The retractable ramp 136 includes a base plate 1361 and a sub-plate 1362. The sub-plate 1362 can be retracted within the base plate 1361 and extended from the base plate 1361 to contact the ground. The length of the sub-plate extending from the base plate can be adjusted according to the required height of the evacuation passage, thereby adjusting the slope of the evacuation passage.

[0064] In some embodiments, multiple levels of sub-plates may be provided, and the slope of the evacuation passage may be adjusted by the number of levels of the sub-plates extended.

[0065] The retraction mechanism 137 is located at the end of the pedal away from the telescopic ramp, as shown in Figure 11. It includes a first rotary motor 1371, a second rotary motor 1372, a first rope winding shaft 1373, a second rope winding shaft 1374, a first steel wire rope 1375, a second steel wire rope 1376, a first telescopic support rod 1377, a second telescopic support rod 1378, a first folding cylinder 1379, a second folding cylinder 1380, a first folding link 1381, and a second folding link 1382.

One end of the second steel wire rope 1376 is fixed to a side of the telescopic ramp 136 corresponding to the first telescopic support rod 1377, and the other end passes through a steel wire rope through hole and is fixed to the second rope winding shaft 1374. By rotating the motor, the rope shaft can be driven to rotate, thereby tightening the wire rope and folding the telescopic ramp 136 back onto the pedal 133. In addition, the wire rope on the side of the telescopic ramp also plays a role of a certain guardrail, preventing people from falling off the evacuation device in a panic.

[0066] In some embodiments, a first telescopic support rod 1377 is located on the side of the pedal 133 away from the rail vehicle door exit, and a second telescopic support rod 1378 is located on the side of the pedal 133 closer to the rail vehicle door exit. A rope threading post 1338 is also provided within the second receiving slot 1335 of the pedal 133, behind the cylinder seat 1337. Rope threading post 1338 has a through-hole. A rope threading hole 1339 is provided on the side panel of the second receiving slot 1335 near the pivot axis 1333. The first steel wire rope 1375 passes through the top of the second telescopic support rod 1378, then through the rope threading post 1338 and rope threading hole 1339 within the second receiving slot 1335, and is secured to the side of the telescopic ramp 136 near the vehicle door. Therefore, a first steel cable 1375 forms an inclined guardrail at the end of the pedal 133 away from the retractable ramp 136. This guardrail is located within the second receiving slot 1335 at the rail vehicle exit, preventing pedestrians from walking. Furthermore, when the first steel cable 1375 is tightened, it smoothly drives the retractable ramp 136 to fold.

The fourth folding link 1384 is fixed to the second telescopic support rod 1378. The folding cylinder drives the folding connecting rod, so that the first telescopic support rod 1377 and the second telescopic support rod 1378 can be folded into the first receiving groove 1334. In some embodiments, the telescopic support rod can be a cylinder or the like.

[0068] A rail vehicle in the present application can deploy the rail vehicle evacuation device at the bottom of the car in an emergency to form an evacuation passage. First, the telescopic drive mechanism 120 can extend the ramp body 130 together with the skirt 300 from under the car floor, and then the retraction mechanism 137 is deployed, the lifting mechanism 132 lifts the pedal 133, and the flip cylinder 134 flips the telescopic ramp plate 136. At the same time, the sub-plate 1362 abuts the ground, and passengers can go down the ramp to the installation position. In some embodiments, the slope width of the ramp body 130 can be 0.6m, and the length of the pedal 133 and the telescopic ramp plate 136 is 1.4m. The width refers to the side length perpendicular to the vehicle's forward direction, and the length is the side length parallel to the vehicle's forward direction. This setting can make the slope of the evacuation passage reach 30 degrees, forming a more comfortable walking slope.
