Problems solved by technology
[0003] Due to the large difference in the length and door size of different models passing through the high-speed rail station, when setting the platform safety door, the opening position of the platform door needs to be adjusted according to the vehicle type. That is to say, the high-speed rail platform safety door adopts a mobile side box or In this way, the automatic lock installed on the side box or the machine head for locking the two doors that can slide relatively should also be mobile. However, the traditional automatic locks for sliding doors (usually electromagnetic locks) are It is installed in the top box or side box of a fixed structure. When the traditional sliding door electromagnetic lock is installed on the high-speed rail platform door, the electromagnetic lock needs to ensure that the two adjacent surfaces of the two halves of the lock fit together so that the two halves of the lock can be absorbed firmly. , the movement of the opening and closing position of the sliding door makes it more difficult to lock the electromagnetic lock; when the circuit in the top box or side box fails or the power is cut off, the electromagnetic lock will automatically open and the sliding door cannot be locked; in addition , the structure of the traditional electromagnetic lock for sliding doors is complex, and there is a problem that it is impossible to judge whether the two suction surfaces of the electromagnetic lock are aligned, and when it should be energized and locked, which increases the difficulty of electromagnetic lock control

The invention relates to the technical field of high-speed rail station doors, and discloses a double-machine-head movable safety door automatic lock for a high-speed rail station, which is reliable in structure, cannot be automatically disconnected and failed after being locked, is easy to lock and is low in control difficulty, and comprises a first lock head and a second lock head which are mounted on two doors which slide relatively, the first lock head and the second lock head respectively comprise electromagnets, connecting rod mechanisms, semi-cylindrical lock cylinders and sliding bearing sleeves, wherein each reset spring is arranged on the corresponding electromagnet, and each semi-cylindrical lock cylinder is rotatably arranged in the corresponding sliding bearing sleeve and is provided with a locking plane. According to the automatic lock, through door body inertia, the sliding bearing sleeves on the two lock heads are close and attached; after the two semi-cylindrical lock cylinders get close to the two locking planes to be attached, the connecting rod mechanisms are driven to be folded through elastic force of the reset springs, so that the two semi-cylindrical lock cylinders rotate in the sliding bearing sleeves, an included angle is formed between the attaching part of the two locking planes and the horizontal plane to lock the lock heads, and when the electromagnets are powered on, the reset springs are compressed, the connecting rod mechanisms are unfolded, and the two semi-cylindrical lock cylinders rotate to open the lock heads.
Description
technical field [0001] The invention relates to the technical field of high-speed rail platform doors, in particular to an automatic lock for a double-head mobile safety door used on a high-speed rail platform. Background technique [0002] The high-speed rail platform is a section of platform set in the railway station and located on the edge of the track of the passing high-speed rail train, which is parallel to the train door steps and provides passages for passengers to get on and off the train. At present, there are no screen doors or safety doors installed on the high-speed rail platform, and it is easy for passengers to jump over the track area, luggage and sundries to be sucked into the track by non-stop trains, or passengers to be pushed into the track area, which will lead to safety accidents. [0003] Due to the large difference in the length and door size of different models passing through the high-speed rail station, when setting the platform safety door, the o...
