A lower end of a first widthwise end of the door leaf 140 is pivotally connected to the bottom adjustment device 120. Thus, the door leaf 140 can be rotated to flip between the door-open position and the door-closed position. As shown in fig. 1 to 3, when the door 140 is located at the closed position, the width direction of the door 140 is parallel to the length direction of the door frame 110 (i.e., the length direction of the top beam 111), and the door 140 closes the doorway of the door frame 110. The emergency door is in a closed state at the moment.

When the door 140 is in the open position, the width direction of the door 140 is perpendicular to the length direction of the door frame 110, and the door 140 opens the doorway. The doorway can now communicate between the landing side and the track side. The emergency door is in an open state.

Preferably, referring back to fig. 4, a sealing groove is formed at an end of the door frame in a width direction of the door 140. The emergency door also includes a seal 190. Seal 190 snaps into a seal slot. With the sash 140 in the closed door position, the sealing member 190 of the sash 140 is pressed against the door frame 110 to seal the space between the sash 140 and the door frame 110.

As shown in fig. 1 to 3, the door leaves 140 are two. The two door leaves 140 are sequentially disposed along the longitudinal direction of the door frame 110. The ends of the two leaves 140 remote from each other are pivotally connected to the door frame 110. Thus, the emergency door is a side-by-side door. At this time, the end of the first door leaf 140 close to the second door leaf 140 is provided with a sealing member 190.

In this embodiment, the position of the reset device 130 relative to the top beam 111 can be adjusted along the length direction of the door frame 110, and the position of the bottom adjustment device 120 relative to the top beam 111 can be adjusted along the length direction of the door frame 110, so that when the emergency door is installed, the position of the door leaf 140 can be adjusted by adjusting the positions of the reset device 130 and the bottom adjustment device 120, so that the length direction of the door leaf 140 located at the door closing position is parallel to the length direction of the upright column 112, and further the width dimension of the gap between the door leaf 140 and the door frame is within the preset range, so as to secure the door leaf 140, and avoid the interference between the door leaf 140 and the door frame 110, thereby facilitating the installation of the emergency door.

Preferably, the return means 130 is a day spring. The top spring is a hydraulic door closer. The top spring is pressed tightly by the turbine. For the floor spring, the floor spring is installed below the doorsill, and the roof spring is installed above the door body and hidden in a base of a structure for installing the door leaf. Thereby, the model selection of the reset device 130 is facilitated.

As shown in fig. 7, the body 131 of the resetting device 130 is provided with a regulating valve. The top beam 111 has an adjustment hole 113 corresponding to the adjustment valve. The staff at the platform can operate the adjusting valve through the adjusting hole 113 to adjust the rotating speed and driving force of the square shaft 133, and thus the speed and force at which the reset device 130 drives the door leaf 140 to rotate.

Preferably, referring to fig. 12 and 16, the bottom adjustment device 120 includes a ground shaft 121, a ground shaft support 122 and a ground shaft adjustment member 123. The ground shaft 121 includes a first shaft section, a second shaft section, and a connecting portion. The first shaft section and the second shaft section are both cylindrical structures. The diameter of the first shaft section is greater than the diameter of the second shaft section. The first shaft section and the second shaft section are coaxially arranged. The connecting portion is connected to an end face of the second shaft section remote from the first shaft section. The connecting part is provided with two ground shaft connecting surfaces which are parallel to each other.

The lower surface of the door frame has a door bottom coupling hole 142. The door bottom attachment hole 142 includes a door bottom attachment surface. The connecting portion is inserted through the door bottom connecting hole 142. The ground shaft connecting surface and the door bottom connecting surface are parallel at this time, so that the ground shaft 121 can rotate together with the door frame.

The ground shaft adjusting part 123 and the ground shaft supporting part 122 are both sheet metal parts. The ground shaft support 122 has a ground shaft support hole. The inner diameter size of the earth shaft supporting hole is smaller than the diameter size of the first shaft section. The second shaft section is rotatably arranged in the ground shaft supporting hole in a penetrating way. Thus, the connecting portion protrudes out of the ground shaft support 122. The ground shaft support 122 blocks the first shaft segment.

The threshold 150 has a ground shaft mounting hole. The inner diameter of the earth shaft mounting hole is larger than the diameter of the first shaft section. Ground axis support 122 is attached to the surface of rocker 150 near top beam 111. Ground axis adjuster 123 is attached to the surface of threshold 150 remote from top beam 111. Thus, the first shaft section is located within the ground shaft mounting hole and between the ground shaft support 122 and the ground shaft adjustment member 123. A space is provided between the outer peripheral surface of the first shaft section and the inner surface of the ground shaft mounting hole.

The ground shaft support 122 has a through hole. The ground shaft adjusters 123 each have a threaded hole. The fastening member is screwed to the screw hole of the ground shaft adjusting member 123 after passing through the through hole of the ground shaft supporting member 122 and the bottom long hole 151 in sequence. So that the ground shaft 121 is connected to the rocker 150. When the emergency door is installed, the position of the ground shaft 121 in the longitudinal direction of the door frame 110 may be adjusted by the bottom long hole 151. Therefore, the emergency door is simple in structure. Further, the operation of adjusting the position of the ground shaft 121 in the length direction of the door frame 110 is simple.

Preferably, as shown in fig. 4, 7-10, 13-15, and 17-19, the emergency door further includes a lock and a latch assembly. The lock assembly can be a lock assembly of the prior art, and the working principle of the lock assembly is not repeated here. The latch fitting is fixedly arranged. The lock assembly includes a first operating portion 181 and a locking portion. The locking portion is located at a second end of the door 140 in the width direction of the door 140. The first operation portion 181 is a push rod. The length direction of the push rod is parallel to the width direction of the door leaf 140. The first operating portion 181 is movably connected to the door 140 in a height direction of the door 140. One end of the first operating portion 181 is connected to the locking portion.

The locking portion is movably connected to the door leaf 140. The locking portion has a locked position and an unlocked position. With the locking portion in the locking position, a portion of the locking portion protrudes out of the doorframe of the door leaf 140 to be locked to the locking member. With the locking portion in the disengaged position, the locking portion is positioned within the doorframe of the door leaf 140 to disengage the locking member. At this time, the door 140 can be unlocked.

One end of the first operating part 181 is connected to the locking part to interlock the first operating part 181 and the locking part. The first operation portion 181 is moved in the height direction of the door 140 to move the locking portion between the locking position and the separated position. Thus, the platform operator can operate the first operating portion 181 to move the locking portion between the locking position and the leaving position. This allows the door 140 to be manually locked or unlocked.

Preferably, as shown in fig. 2 and 3, the first operating part 181 is located at a track side of the door leaf 140 close to the track. This can prevent the passenger from operating the first operation unit 181 by mistake.

Preferably, the lock assembly also includes a second operating portion 186 and an operating tool (e.g., a key). The operating tool is used to operate the second operating portion 186. The platform side surface of the door leaf 140 facing away from the track has a lock hole 185. The second operating portion 186 is located at the locking hole 185. The second operating portion 186 is connected to the locking portion. The second operation portion 186 is operable to move the locking portion between the locking position and the release position. The second operation portion 186 can be operated through the lock hole 185. Thus, the platform operator operates the second operating portion 186 by the operating tool at the platform side away from the rail to move the locking portion between the locking position and the departing position. Thus, the operation of the second operation portion 186 is safe.

As shown in fig. 7, 8, 14 and 15, the position of the locking member with respect to the top rail 111 can be adjusted in the width direction of the door frame 110. Therefore, when the emergency door is installed, the locking degree of the door leaf 140 is conveniently adjusted.

Preferably, the locking element has a lock slot 184. The long axis of the lock slot 184 is parallel to the width direction of the doorframe 110. The locking member is connected and fixed to the locking slot 184 by a fastener. Therefore, the locking piece has a simple structure. In addition, it is convenient to adjust the position of the locking member with respect to the doorsill 150 in the width direction of the door frame 110.

Specifically, as shown in fig. 4, 13-15, the lock includes a lower lock 172. The lower locking member 172 has the aforementioned locking slot 184. Lower latch 172 is connected to threshold 150 by a fastener and latch slot 184. The lower lock 172 has a locking hole 185. The locking portion includes a lower locking portion 183. With the locking portion in the locked position, the lower locking portion 183 extends out of the lower end of the doorframe to extend into the locking hole 185. Thus, the lower locker 172 has a simple structure.

As shown in fig. 4, 7-10, and 17-19, the lock includes a detent 171. The lock pin 171 has a pin hole. A locking pin 171 is attached to the top rail 111.

The locking portion includes an upper locking portion 182 and a locking member 250 (e.g., a locking tongue). The upper and lower locking portions 182 and 183 move together. When the upper locking portion 182 is in the locking position, the lower locking portion 183 is also in the locking position. When the upper locking portion 182 is located at the spaced position, the lower locking portion 183 is also located at the spaced position. When the locking portion is in the locking position, the upper locking portion 182 extends out of the upper end of the door 140 to enter the pin hole.

The locking member 250 is rotatably disposed between a hooked position and an unlocked position. With the locker 250 in the hooking position, the locker 250 can be hooked to the locking pin 171 to lock the upper end of the door leaf 140 to the header 111. With the lock 250 in the unlocked position, the lock 250 is moved away from the detent 171 to release the catch of the detent 171. The locker 250 and the upper locker 182 are interlocked such that the locker 250 rotates between the hooking position and the unlocking position during the movement of the upper locker 182. When the upper locking portion 182 is located at the locking position, the upper locking portion 182 can drive the locking member 250 to rotate to the hooking position. Thereby, the upper end of the door leaf 140 can be more firmly locked to the top beam 111.

The lock pin 171 has the aforementioned lock slot 184. The locking pin 171 is connected to the top rail 111 by a fastener and a locking slot 184. Thus, the position of the locking pin 171 with respect to the top beam 111 can be adjusted in the width direction of the doorframe 110.

Preferably, referring to fig. 2 and 8, the panic door further comprises a damping assembly 200. The damping assembly 200 is connected to the top rail 111. The cushion assembly 200 has a support portion 201 and an elastic portion 202. The support 201 is a metal member. The elastic portion 202 is a non-metal member (e.g., a rubber member). The support 201 includes a horizontal arm and a vertical arm. The plane of the horizontal arm is perpendicular to the plane of the vertical arm. The horizontal arm is attached to the lower surface of the top beam 111. The horizontal arm is connected to the top beam 111 by fasteners. The vertical arm is located below the top beam 111. The plane of the vertical wall is perpendicular to the width direction of the door frame 110. The vertical wall is attached to the elastic portion 202. The resilient portion 202 is located on the side of the vertical arm remote from the track. Thus, the elastic portion 202 is located below the top beam 111, and when the door 140 moves to the closed door position, the vertical wall can block the door 140, so that the door 140 stops at the closed door position. Further, the elastic portion 202 can prevent the door 140 from hitting the vertical wall, and can protect the door 140.

Due to the arrangement of the buffer assembly 200, under the condition that the passenger presses the door leaf 140, the door leaf 140 can be protected, the door leaf 140 is prevented from bending and deforming towards the rail, and the reset device 130 is prevented from being damaged.

Preferably, as shown in fig. 1, in the width direction of the door leaf 140, a platform side surface of the second end of the door leaf 140 far from the track is recessed toward a track side surface close to the track to form a catcher groove 141. Thus, the door 140 can be operated through the catching groove 141.

Preferably, as shown in fig. 2 and 3, the rail-side surface of the door leaf 140 adjacent to the rail has an access hole. The locking portion of the lock assembly can be accessed through the access hole. The emergency door also includes an access panel 240. The service cover 240 is connected to the rail-side surface of the door leaf 140 by a fastener to cover the service hole. From this, conveniently overhaul the locking portion of tool to lock subassembly.

As shown in fig. 1 to 8, the panic door further comprises a first controller 220, a second controller (not shown), and a sensor 210. A first controller 220 and sensor 210 are connected to the top beam 111. The sensor 210 is electrically connected to the first controller 220. The sensor 210 is electrically connected to the second controller. The sensor 210 is used to sense a sensing signal indicating that the door leaf 140 is located at the closed door position or the open door position. The sensor 210 transmits a sensing signal sensed by the sensor to the first controller 220 and the second controller. The first controller 220 and the second controller register the sensing signal of the sensor 210.

The emergency door further includes a status indicator light (not shown) electrically connected to the first controller 220. The status indicator lamp is connected to the door frame 110. The first controller 220 transmits a signal to the status indicator lamp according to the sensing signal to control the operation of the status indicator lamp. Specifically, when the door 140 is opened (the door 140 is located at the door-open position), the first controller 220 controls the status indicator lamp to operate in a manner indicating that the door 140 is opened (for example, the status indicator lamp is turned on). When the door 140 is closed (the door 140 is located at the closed door position), the first controller 220 controls the status indicator lamp to operate in a manner indicating that the door 140 is closed (e.g., the status indicator lamp is not turned on).

Preferably, the sensor 210 has a knock pin. When the door 140 is in the closed position, the upper locking portion 182 extends out of the door frame to push the top pin to move upward, thereby triggering the sensing signal of the sensor 210. The sensing signal of the sensor 210 is a closing signal indicating that the door 140 is in the closed position.

When the door 140 is moved away from the closed position, the upper lock portion 182 is moved away from the knock pin. At this time, the knock pin moves downward by gravity and by the elastic force of the switch of the sensor 210, thereby triggering the sensing signal of the sensor 210. The sensing signal of the sensor 210 is an open signal indicating that the door 140 is located at the door-open position.

The emergency door also has a normal state and a fault state.

For a certain emergency door, if the emergency door is in a normal state, it indicates that the sensor 210 of the emergency door is working normally. At this time, the sensing signal received by the second controller with respect to the emergency door indicates the same position of the door leaf 140 as the actual position of the door leaf 140. If the panic door is in the fault state, it indicates that the panic door sensor 210 is faulty. At this time, the sensing signal received by the second controller with respect to the emergency door indicates that the position of the door leaf 140 is different from the actual position of the door leaf 140.

It should be noted that the actual position of the door leaf 140 can be obtained by other devices (e.g., video monitors) electrically connected to the second sensor.

The second controller determines the operation state of the emergency door by sensing the signal and the actual position of the door leaf 140. And if any one emergency door in the station is in a fault state, the second controller prohibits the vehicle from entering the station. If all the emergency doors in the station are in the normal state, the second controller permits the vehicle to enter the station.

Preferably, the emergency door further includes a controller lock head 230, a tool (e.g., a key) corresponding to the controller lock head 230, and a malfunction alarm (e.g., a malfunction signal lamp). The controller latch 230 is connected to the top rail 111. The operator may operate the controller latch 230 via a tool corresponding to the controller latch 230 to rotate the controller latch 230 between the first position and the second position. The malfunction alarm is connected to the door frame 110. The fault alarm is electrically connected to the second controller.

If the second controller determines that a certain emergency door of the station is in a normal state, the controller lock 230 may be located at the first position. At this time, the second controller normally acquires the sensing signal of the emergency door.

If the second controller judges that a certain emergency door is in a fault state, the second controller controls the fault alarm to work. When the staff at the station sees that the fault alarm works, the controller lock head 230 of the emergency door can be located at the second position. At this time, the controller latch 230 short-circuits the sensor 210 from the circuit of the second controller, so that the signal of the sensor 210 cannot be transmitted to the second controller, so that the second controller no longer determines the state of the emergency door, and the station can normally operate.
