Description
Technical Field
The invention relates to subway platform corollary equipment, in particular to a subway train stop closed safety device which can shield or utilize tunnel negative pressure ventilation in a time-sharing manner, save energy and simultaneously ensure the riding safety of passengers on and off.
Background
At present, the urban rail transit platform screen door facility is widely applied to various subway stations and generally divided into a fully-closed screen door and a semi-closed screen door (safety door). At present, a safety door system is generally adopted in underground stations in severe cold areas, and a fully-closed shielding door system is generally adopted in newly-built underground stations in other areas except the severe cold areas. No matter which system is adopted, in order to ensure the safety and reliability of the train in operation, when the train stops, a safety gap of about 15cm exists between the train and the platform, and the shielding door is generally arranged on the inner side of the platform which is 15cm-20cm away from the edge line of the platform, so that a gap of 30cm-35cm exists between the train and the shielding door when the train stops.
For the existing totally-enclosed shield door, from the perspective of energy consumption of ventilation and air conditioning, in summer when the temperature of outdoor air is high, the shield door of a train stops and is opened, and due to the existence of the heat-exhausting fan in the tunnel, cold air in the station flows into the tunnel and hot air in the outdoor air flows into the station, so that the load and the energy consumption of air conditioning equipment are objectively increased. But it is advantageous to reduce the load and power consumption of the air conditioner in the ventilating season where the outdoor air temperature is low. At the same time, a gap of several tens of centimeters also presents a significant safety risk for most people, especially children.

Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Referring to fig. 1, the subway train stop closed energy-saving and safety device comprises a shielding door 2 and a shielding door frame 1, wherein a semi-surrounding structure 3 is fixedly arranged on the outer side wall of the shielding door frame 1, the inner end of an outer corridor 4 is fixedly connected with the semi-surrounding structure 3, an inner corridor 5 is nested in the outer corridor 4, a hard rubber frame 6 is fixedly arranged on the outer port of the inner corridor 5, and the shape of the outer port of the hard rubber frame 6 is matched with the side surface of a train. And a driving device acting on the inner gallery 5 is arranged on the semi-surrounding structure 3 and used for driving the inner gallery 5 to move outwards until the outer port of the hard rubber frame 6 is contacted with the surface of the train and move inwards to return. Referring to fig. 3, the driving device is controlled by a controller 19, and the controller 19 receives an outdoor temperature value and a barrier gate switching signal collected by a temperature sensor 20, and determines whether the driving device is linked with the barrier gate switching signal according to the outdoor temperature value.
Referring to fig. 3, the controller 19 sets an upper limit operating temperature and a lower limit operating temperature. When the outdoor temperature value is higher than the upper limit action temperature, the driving device is linked with the shielding door switch signal. And when the outdoor temperature value is lower than the lower limit action temperature, the driving device stops acting. In addition, the driving device is controlled by the safety button 21, and when special conditions such as maintenance or power failure occur, the driving device can be reset through the safety button 21, so that the normal operation of the train is prevented from being interfered.
The controller 10 is a programmable Controller (CPU) and is installed in an electric control box, and a distributor for supplying power to the electric control box is further provided in the electric control box. Referring to fig. 3, typically, the upper limit operating temperature may be set to 28 ℃ and the lower limit operating temperature may be set to 26 ℃. The control strategy of the controller 19 is that when the outdoor temperature value collected by the temperature sensor 20 is higher than 28 ℃, the driving device is linked with the shielding door switch signal; when the outdoor temperature value collected by the temperature sensor 20 is lower than 26 ℃, the driving device does not act. The temperature sensor 20 may be typically provided at the station-out entrance.
Referring to fig. 2 and 4, the driving device is disposed on two lateral sides of the semi-surrounding structure 3 and includes a hydraulic push rod 10, a connecting rod 16, a sliding block 14 and a concave sliding rail groove 13, the concave sliding rail groove 13 is disposed on the outer end of two lateral sides of the inner gallery 5, the inner ends of the hydraulic push rod 10 and the connecting rod 16 are hinged to the semi-surrounding structure 3, the outer end of the hydraulic push rod 10 is hinged to the middle of the connecting rod 16, and the outer end of the connecting rod 16 is hinged to the sliding block 14 in the concave sliding rail groove 13. The hydraulic push rod 10 is driven by the gear pump 9 and the oil cylinder 8, and the controller 19 controls the gear pump 9 to operate. The cross section of concave sliding rail groove 13 is spindle-shaped, and sliding block 14 is retrained in the inslot, and the lower extreme of concave sliding rail groove 13 is fixed and is set up rail groove separation blade 15 to avoid under extreme conditions sliding block 14 to deviate from concave sliding rail groove 13 lower extreme. Referring to fig. 4, rolling bearings 12 are arranged on the inner walls of the two longitudinal sides of the outer gallery 4 between the outer gallery 4 and the inner gallery 5, and anti-disengaging hooks 17 corresponding to the rolling bearings 12 are arranged on the outer walls of the two longitudinal sides of the rear end of the inner gallery 5.
Referring to fig. 1, the outer corridor 4 is fixedly disposed outside the screen door 2 to form a platform outside the screen door, and the width L1 of the platform outside the screen door is generally 20cm to 25 cm. Even if the inner gallery 5 does not extend outward, the parking gap L2 is only 10-15 cm, which is enough to ensure the safety of passengers getting on and off the vehicle.
Referring to fig. 2 and 3, the working process of the closed energy-saving and safety device for the stop of the subway train is as follows:
1. gradual reduction of outdoor temperature
When the temperature of the air at the inlet and the outlet of the station is reduced and the temperature sensor 20 detects that the temperature value of the outdoor air is lower than 26 ℃, the controller 19 controls the gear pump 9 not to be started, and under the condition that the train runs and the station is stopped and is static, the gear pump 9 does not drive the hydraulic push rod 10 to act, and a gap (a stopping gap L2) between the train and the platform exists all the time. This typically occurs during the transition season during which the outdoor air temperature is reduced.
2. Gradual rise of outdoor temperature
When the temperature of the air at the inlet and the outlet of the station rises and the temperature sensor 20 detects that the temperature value of the outdoor air is higher than 28 ℃, the controller 19 controls the gear pump 9 to be in signal communication with the shielding door, and then the hydraulic push rod 10 is driven to act. After the train stops at a standstill, the operation is extended for a certain time (such as 0.5s) before the shielding door 2 is opened, so that the inner gallery 5 moves outwards until the outer port of the hard rubber frame 6 is contacted with the surface of the train, and the stopping gap L2 is eliminated. Before the train is ready to be out of the station, the gear pump 9 drives the hydraulic push rod 10 to act and contract for a certain time (such as 0.5s) before the shielding door is closed, so that the inner gallery 5 moves inwards to return, and a sufficient safety gap is reserved for the train to run. This situation typically occurs during the summer when the outdoor air temperature increases.
When special conditions such as maintenance or outage occur, the staff can make a judgment according to professional knowledge of the staff, and regulate and control the action of the driving device and the position of the inner corridor 5 through the safety button 21, so that a sufficient gap is reserved for the safe operation of the train.
The foregoing is illustrative of the principles of the present invention for a closed energy saving and safety device for a subway train stop, and is not intended to limit the invention to the exact construction and operation shown and described, and accordingly, all modifications and equivalents that may be resorted to are intended to fall within the scope of the invention.
