Technical Field

The invention belongs to the technology of locking a cab of a railway vehicle, and particularly relates to a locking system of a partition wall door.

Background

The traditional partition wall door is locked by a mechanical lock pressed by a handle in a rotating way, so that passengers are prevented from entering the cab, a crew member can open the partition wall door of the cab from the inside of the cab to enter the cab, and a special key is required to be used when the crew member enters the cab from the cab.

However, since the subway vehicles are generally used by a single driver, if the vehicles are forced to stop in the operation area due to special situations and need to be emergently evacuated through escape doors at two ends, the drivers are required to walk from one end of the train to the other end to open the partition wall door, operate the escape doors and evacuate passengers to escape. If the train consists of a long train or has more passengers, it takes a long time for the crew members to get to the other end of the train, and if a serious fire accident occurs in the train at this time, the life safety of the passengers is seriously threatened.

Therefore, the traditional cab bay door adopting the mechanical lock mode is not suitable for the emergency evacuation of the train.

Disclosure of Invention

The invention aims to provide a locking system for a cab partition door, which can be opened by a vehicle operator in various forms, so that the situation that the vehicle operator is trapped in the cab and cannot escape under the condition that a single partition door locking system mechanism fails in an unexpected situation is avoided.

In order to achieve the above object, the present invention provides a locking system for a cab bay door of a railway passenger car, characterized in that: the magnetic lock comprises a voltage stabilizer, a control box, a button switch, a key switch, a magnetic lock, a door magnetic induction switch and a driver station control switch, wherein the voltage stabilizer is connected with the control box and fixed on a straight dividing wall; the button switch and the key switch are respectively fixed on two sides of the straight partition wall and are connected with the control box; the magnetic lock is fixed on the straight partition wall and is attracted with a metal plate arranged on the partition wall door when being electrified; the door magnetic induction switch is fixed on the partition wall door and connected with the control box; the driver station control switch is arranged on the driver station and is connected with the control box.

The door magnetic induction switch is provided with a half of conducting wires and is arranged on the door frame, the other half of the conducting wires are arranged on the door panel in parallel, the position change of the door panel in opening and closing is detected, information is fed back to the main control panel, and power supply locking is carried out on the magnetic lock.

The button switch and the key switch are respectively wired in the framework type cavity in the straight partition wall.

The gate magnetic induction switch is wired in the framework type cavity inside the straight partition wall.

The magnetic lock is electrified to generate strong suction to suck the metal plate fixed on the partition wall door, thereby achieving the locking effect. The system needs to be powered by a DC24V power supply, and the vertical tension of the magnetic lock reaches 3000N. The unlocking mode can be realized by remotely sending an unlocking signal (switching value signal) through a vehicle control center, and can also be unlocked in a cab through a button switch and can also be unlocked in a passenger room through a key switch. When the vehicle operator unlocks in any mode, the magnetic lock (power failure) loses the adsorption force, the door can be opened, and the unlocking delay time can be set to be 5-20 seconds. If the door is not opened after the set time limit is exceeded after unlocking, the system can automatically lock. When the door is in an open state, the magnetic lock is not electrified, power consumption is saved, and the door magnetic induction structure can feed back the position state of the door. According to the invention, under the condition that an accident occurs to the vehicle, the escape probability of the vehicle personnel for opening the partition wall door is greatly improved, and the safety of the vehicle is improved.

Detailed Description

As shown in fig. 1-6, the cab partition door locking system is composed of a voltage stabilizer 1, a control box 2, a button switch 3, a key switch 4, a magnetic lock 5, a door magnetic induction switch 6, and a cab console control switch 7. The voltage stabilizer 1 and the control box 2 are fixed on the straight partition wall 8 through screws, and the voltage stabilizer 1 and the control box 2 are connected through electric wires; the button switch 3 is fixed on the inner side of the straight partition wall 8 and can be directly used by vehicle operators, the key switch 4 is fixed on the outer side of the straight partition wall, and the vehicle operators need to be matched with keys for use; the button switch 3 and the key switch 4 are respectively wired in a framework type cavity inside the straight partition wall 8 and are connected with the control box 2 by using power lines. The magnetic lock 5 is fixed on the straight partition wall 8 through a screw, wires are arranged in a framework type cavity in the straight partition wall 8, and the magnetic lock is connected with the control box 2 through a power line. The door magnetic induction switch 6 is fixed on the partition wall door 9 through a screw, is wired in a framework type cavity inside the straight partition wall 8, and is connected with the control box 2 through a power line. The driver station control switch 7 is arranged on the driver station, and is connected with the control box 2 through an external wiring and a power line. Half of the door magnetism inductive switch with the wire is installed on the door frame, and the other half is installed on the door plant in parallel, and the main function is to detect the position change (detection distance <30mm) that the door plant opened and closed, feeds back information to the main control board. When the door is switched from the opening position to the closing position, the door magnetic induction switch sends a signal to the main control board after detecting the position change, and the magnetic lock is powered and locked. Two binding posts of the switch can be conducted by pressing a button or rotating a key, and unlocking is triggered.

The working process is as follows: the vehicle power supply outputs DC24V +/-15% voltage to the voltage stabilizer 1, the voltage stabilizer outputs DC24V +/-0.25V constant voltage to the input end of the control box 2 through the primary stabilized voltage of the voltage stabilizer, the output end of the control box 2 outputs current to the magnetic lock 5, the magnetic lock 5 is electrified to generate vertical tension reaching 3000N, and the door is locked.

When the door is locked, the door magnetic induction switch 6 gives feedback signals to the output terminal of the control box 2, the control box 2 decomposes the feedback signals into door state feedback and lock state feedback from the input terminal (c), and the door state feedback and the lock state feedback respectively present locked visual state display information on the partition wall door and the driver station.

When a vehicle operator needs to open a cab bay door, there are three ways:

the first method is as follows: the driver control switch 7 can be used on a driver table, the driver table control switch 7 gives a feedback of cutting off a power supply to an output terminal of the control box 2, an input terminal of the control box 2 cuts off 24V direct current input by the voltage stabilizer 1, an output terminal of the control box 2 outputs a feedback signal which cannot provide current to the magnetic lock 5, electromagnetic induction of the magnetic lock disappears, the door can be opened, the door magnetic induction switch 6 gives a feedback signal to the output terminal of the control box in the process of opening the door, the feedback signal is decomposed into door state feedback and lock state feedback by the input terminal by the control box, and visual door opening state display information is respectively presented on the dividing wall door and the driver table.
