Description

Technical Field

[0001] This application relates to the field of subway technology, and more specifically to a control and debugging method for a full-width electric emergency safety device for A / B type subway vehicles. Background Technology

[0002] As a type of urban transportation, the subway is widely used in major cities because it can effectively alleviate urban traffic pressure. The types include Type A, Type B, and Type C, with the width and passenger capacity decreasing in that order. Major cities in my country generally use Type A or Type B subways with larger passenger capacity.

[0003] The front structure of existing Type A or Type B subway trains mostly features full-width doors, which provides good visibility while ensuring aesthetics. Furthermore, in the event of an emergency, opening the full-width doors can improve evacuation efficiency. Additionally, at the end of the train, near the driver's cab, there is a door-opening mechanism for activating the full-width doors and a retractable evacuation ramp. Once the full-width doors are open, the evacuation ramp extends, allowing passengers to move from the driver's cab to the outside. The full-width doors, door-opening mechanism, and evacuation ramp together constitute an emergency safety device. However, the folding evacuation ramp is located on one side of the driver's cab, and the electrical control cabinet is located on the other side. The existing electrical control cabinet occupies two-thirds of the width of the entire carriage. Therefore, when evacuating passengers, even though the evacuation ramp is unfolded, the number of passengers that can be effectively evacuated through the evacuation ramp per unit time is limited due to the obstruction of the electrical control cabinet. There is room for further improvement in the existing emergency safety device. In addition, considering that the emergency safety device can operate stably in an emergency, the actions of each component of the emergency safety device require corresponding locks and motion control structures. After the installation of each structure, the relevant locks and motion control structures need to be functionally debugged. However, the existing functional debugging method usually debugs a single lock and motion control structure individually, only requiring that the individual lock and motion control structure function normally, without considering the coordination problem during the functional debugging process, or the motion interference that may occur during actual use, affecting the safety of evacuation.

[0004] Therefore, there is a need for a control and debugging method for a full-width electric emergency safety device for A / B type subway cars with good coordination of its components. Summary of the Invention

[0095] Indicative control and debugging methods for full-width electric emergency safety devices on Type A / B subway cars.

[0096] refer to Figures 1 to 6 According to a preferred embodiment of the present invention, a control method for a full-width electric emergency safety device of a type A / B subway vehicle is applicable to electric emergency safety devices of rail trains, wherein each end of the rail train is provided with one of the electric emergency safety devices. Figure 1 As shown, each of the electric emergency safety devices includes a fully open door 10, a door opening mechanism 20, and a first evacuation ramp 30.

[0097] The fully open door 10 is hinged and rotatably mounted on the body of the railcar, located at one end of the railcar. The door opening mechanism 20 includes a first electric push rod 201, a lifting member 202, and a frame. The frame is fixedly connected to the railcar body via a threaded connection. The lifting member 202 is rotatably mounted on the frame. Both ends of the first electric push rod 201 are rotatably connected to the lifting member 202 and the frame, respectively. When the first electric push rod 201 is activated, the lifting member 202 rotates a predetermined angle, causing the fully open door 10 to flip upwards by a predetermined angle. Subsequently, the fully open door 10 is further lifted upwards under the action of multiple gas springs. The first electric push rod 201 is used to open or close the fully open door 10 at a predetermined angle and at a safe height. In addition, the first evacuation ramp 30 is foldably installed on the body of the railcar. The first evacuation ramp 30 is normally locked. In addition, the first evacuation ramp 30 is equipped with a gas spring. When the first evacuation ramp 30 is unlocked, the first evacuation ramp 30 automatically unfolds under the action of the gas spring. Since the evacuation ramp technology is mature and widely used in the market, the specific structure of the evacuation ramp will not be described in detail here. The first evacuation ramp 30 includes, but is not limited to, the evacuation ramp with gas spring disclosed in the patent document (CN201030862Y).

[0098] It should also be noted that in the driver's cab of existing Type A or Type B rail trains, such as Figure 2 As shown, the first evacuation ramp 30 is arranged adjacent to the electrical control cabinet 50. The width of the electrical control cabinet 50 occupies two-thirds of the entire carriage. Therefore, in the event of an emergency, passengers are blocked by the electrical control cabinet 50 and can only evacuate through the narrower first evacuation ramp 30, resulting in low evacuation efficiency per unit time.

[0099] In view of this, the present invention discloses an electric emergency safety device that can evacuate more passengers per unit time. Specifically, the electric emergency safety device further includes a widening evacuation device 40, which is installed on the electrical control cabinet 50 of the railcar. The electrical control cabinet 50 is located on one side of the first evacuation ramp 30.

[0100] like Figure 3 and Figure 4As shown, the widened evacuation device 40 includes a second electric push rod 401, a swing member 402, a sliding member 403, a support member 404, several sequentially hinged stair surfaces 405, a ground lock 406, an end lock 407, a stair surface lock 408, and a second evacuation ramp 409 (see reference). Figure 5 One end of the swing member 402 is rotatably mounted on the electrical control cabinet 50 via a hinge. The two ends of the second electric push rod 401 are rotatably connected to the electrical control cabinet 50 and the swing member 402, respectively. The swing member 402 has a groove 4021, and each side wall of the groove 4021 has a sliding groove 4022. The sliding member 403 is slidably disposed within the groove 4021 of the swing member 402, and one end of the sliding member 403 has a pulley that contacts the body of the railcar. Additionally, a trapezoidal surface 405 at one end is rotatably connected to the swing member 402, and another trapezoidal surface 405 at the other end is locked or unlocked by a trapezoidal surface lock 408. Both ends of the trapezoidal surface 405 are slidably disposed within the sliding grooves 4022, and the trapezoidal surface 405 is located above the sliding member 403. An extension end is present on both sides of the junction of the two trapezoidal surfaces 405. Additionally, the support member 404 is located on both sides of the swing member 402 and is slidably disposed on the swing member 402. The movement direction of the support member 404 is perpendicular to the sliding direction of the ladder surface 405. When the support member 404 slides, the support member 404 contacts the extended end of the ladder surface 405 and lifts the ladder surface 405 or the support member 404 separates from the ladder surface 405. In addition, the ground lock 406 is slidably disposed on the body of the railcar. The end lock 407 and the ladder surface lock 408 are both slidably disposed on the swing member 402. When the second electric push rod 401 slides a predetermined distance, one end of the sliding member 403 locks or separates from the ground lock 406, and the other end of the sliding member 403 contacts or separates from the end lock 407. The second evacuation ramp 409 is connected to the top surface of the electrical control cabinet 50 in a folded manner.

[0101] It should be noted that after the push rod of the second electric push rod 401 extends to a predetermined length, the swing member 402 swings away from the electrical control cabinet 50 by a predetermined angle, and the sliding member 403 slides out of the groove 4021 by a predetermined distance under its own weight. When the swing member 402 is arranged at 45°, the sliding member 403 is directly opposite the floor lock 406. Then the floor lock 406 moves upward a predetermined distance and locks one end of the sliding member 403, and the end lock 407 locks the other end of the sliding member 403 placed in the groove 4021. The position of the sliding member 403 is fixed. Subsequently, the ramp lock is unlocked, and the originally folded ladder surface 405 automatically slides down in a flat manner under its own weight. To make the ladder surface 405 step-like, the... The support member 404 slides upward at a predetermined angle and lifts the extension end on the corresponding step surface 405, causing the sequentially hinged step surfaces 405 to form a stepped shape. Passengers can then move to the top surface of the electrical control cabinet 50 via the stepped step surface 405 and evacuate via the unfolded second evacuation ramp 409 by unlocking it. Since the width of the electrical control cabinet 50 is greater than the width of the first evacuation ramp 30, the specifications of the second evacuation ramp 409 placed on the electrical control cabinet 50 can also be selected to be a wider evacuation ramp, allowing for the evacuation of a larger number of people per unit time. When the first evacuation ramp 30 cannot be unfolded due to an accident, passengers can escape the rail train via the third evacuation ramp, achieving the advantage of evacuating a larger number of passengers per unit time.

[0105] S3. The first electric push rod of the door opening mechanism moves, causing the fully opened door leaf to flip upward to a predetermined angle, and further flip upward to a safe height under the action of the gas spring; determine whether the first electric push rod has extended to the correct position. If yes, that is, the first electric push rod has extended to the correct position, and execute step S4; if no, that is, the first electric push rod has not extended to the correct position, the fault light will alarm, and step S6 will be executed.

[0107] S5. The second electric push rod extends to a predetermined length, and the swinging part rotates to a predetermined angle away from the electrical control cabinet. At the same time, the sliding part automatically extends to a predetermined length. It is determined whether the second electric push rod has extended to the correct position. If yes, that is, the second electric push rod has extended to the correct position, then step S7 is executed. If no, that is, the second electric push rod has not extended to the correct position, then the fault light alarm is triggered.

[0108] S6. The second electric push rod retracts to its initial position and the swinging and sliding components are retracted.

[0112] S10. Unlock the left and right second ramp electronic locks and determine whether both the left and right second ramp electronic locks are unlocked. If yes, that is, both the left and right second ramp electronic locks are unlocked, then the second evacuation ramp will be deployed.
