Generally, the distance between two upright posts 1 is at least 9 m, and at least one door opening position of each train is included between the two upright posts, of course, the length of the train is very long, more upright posts 1 and more groups of pull ropes 3 are arranged for safety shielding of the whole platform, and the shielding door adopting the pull rope 3 structure is suitable for opening doors of different trains, and the shielding door of the whole platform is lighter and more energy-saving in opening and closing.
When the pull rope 3 is lifted, the lifting column 2 is arranged on the upright 1, a balance weight 13 is arranged on the upright 1, a driving machine 11 and a driving chain 12 connected with the driving machine 11 are arranged at the top end of the upright 1, one end of the driving chain 12 is connected with the lifting column 2, and one end of the driving chain 12 away from the lifting column 2 is connected with the balance weight 13; thus, the driving machine 11 works to drive the driving chain 12 to transmit and drive the lifting column 2 to lift, when the driving machine 11 rotates positively, the lifting column 2 rises, the balance weight 13 descends, otherwise, when the driving machine 11 rotates reversely, the lifting column 2 falls, the balance weight 13 ascends, the lifting column 2 and the balance weight 13 are respectively arranged on two sides of the driving machine 11 to balance the lifting force of the lifting column 2, and then the lifting of the lifting column 2 can be completed by smaller power of the driving machine 11.
And the driving machine 11 is provided with a driving chain wheel 111, and the driving chain 12 is in meshed connection with the driving chain wheel 111, so that the lifting of the pulling rope can be matched with the rotation of a motor shaft of the driving machine better.
Therefore, the lifting of the pull rope 3 is provided with the balance weight 13 to balance the gravity, so that the lifting of the pull rope on the fault side is easier, and one person can easily lift the pull rope.
The main point of the present utility model is that the driving machine 11 is connected with a lifting control part, the lifting control part comprises a controller, a signal intercommunication device and an absolute value encoder connected with the rotating shaft of the driving machine 11, the absolute value encoder and the signal intercommunication device are both electrically connected with the controller, the absolute value encoder continuously works, the rotating quantity of the rotating shaft of the driving machine is continuously obtained, and the signal intercommunication device can be used only when one side motor fails.
The method comprises the following steps:
s1: judging whether the driving machine works normally or not, if so, not executing operation; otherwise, executing the step S2;
under normal conditions, the driving machine drives the pull rope to lift under driving control, and the pull rope is not required to be pushed by manpower to lift; once the one-side driving machine fails, the upright posts on both sides of the pull rope are required to cooperate, so that the pull rope is lifted under the control of manpower, that is, step S2 is performed.
In the present utility model, when step S1 is executed, the judgment criteria for abnormal operation of the drive machine are: after the drive signal is sent to the drive machine, the drive machine does not respond beyond a preset time.
Also, as an embodiment of the present utility model, when the drive machine is not operating normally while step S1 is performed, an alarm is issued, and step S2 is performed; of course, the alarm mode includes an audible alarm and a flashing alarm, and because the driving control has sent a driving signal to the driving machine, that is, the emergency gate needs to be lifted and moved, but the driving machine does not correspond to the driving machine, an alarm needs to be sent to remind the staff to lift and move the emergency gate manually.
For example, in the closed state of the emergency gate, that is, when the pull rope is positioned at the bottom, the pull rope separates a platform from a train at the moment, if the train enters the station, the driving control sends a door opening signal to the driving machine, but the driving machine does not correspond, an alarm is sent at the moment, and a worker manually lifts the pull rope to open the emergency gate, so that the train can get on or off conveniently.
S2: the lifting control part at the abnormal driving machine is marked as a first control part, and the lifting control part at the driving machine at the other end of the pull rope is marked as a second control part; the controller of the first control part acquires the reading of the absolute value encoder in real time;
the side of the driving machine which does not respond is actually an abnormal side, the other end of the pulling rope is a normal side, the driving machine on the abnormal side is marked as a first driving machine, and the lifting control part on the abnormal side is marked as a first control part; the normal side drive machine is denoted as a second drive machine, and the normal side lift control portion is denoted as a second control portion.
At the moment, the lifting control of the safety door stay cord is required to be manually carried out, at the moment, the system automatically starts the controllers of the first control part and the second control part and the signal intercommunication device, and then the controller of the first control part acquires the readings of the absolute value encoder in real time.
S3: judging whether the absolute value encoder reading of the first control part changes or not; if yes, executing step S4; otherwise, not executing the operation;
here, the change in the absolute value encoder reading of the first control section means: and in the step S2, the controller of the first control part acquires the absolute value encoder reading as an initial reading, and in the step S3, the absolute value encoder reading of the first control part is changed compared with the initial reading.
At this time, the platform staff reaches the position of the abnormality of the driving machine, and according to the information of the train entering and exiting, the lifting control is manually performed on the pull rope of the safety door, and the door opening of the safety door is taken as an example, namely the pull rope needs to be lifted.
The station staff lifts the pull rope at the abnormal side, the lifting of the pull rope can be transmitted to the rotating shaft of the driving machine through the driving chain to rotate (the driving machine fails, but the rotating shaft of the driving machine can still rotate), and then the reading of the absolute value encoder can also be changed; otherwise, if the absolute value encoder reading of the first control part changes, then personnel are required to perform lifting control on the pull rope, and at the moment, the next step S4 is required to be continuously executed, so that the synchronous lifting of the two ends of the safety door pull rope is completed.
S4: the controller of the first control part sends the absolute value encoder reading of the first control part to the controller of the second control part in real time through the signal intercommunication device;
here, when step S4 is performed, specifically:
s41: establishing intercommunication connection between the signal intercommunication device of the first control part and the signal intercommunication device of the second control part;
s42: the controller of the first control part sends the readings of the absolute value encoder of the first control part to the signal intercommunication device of the second control part through the signal intercommunication device every interval preset time value;
s43: the controller of the second control part reads the absolute value encoder reading of the first control part received by the signal intercommunication device of the second control part.
S5: the controller of the second control part drives the driving machine to work so that the absolute value encoder reading of the second control part is the same as the absolute value encoder reading of the first control part.
After the controller of the second control part receives the readings of the absolute value encoder of the first control part, the driving machine at the normal side is driven to work according to the readings of the absolute value encoder of the first control part, and the pull rope at the normal side is driven to lift, so that the heights of the two ends of the pull rope are kept the same, namely the two ends of the pull rope lift synchronously.
It should be noted that the height of the pull rope on the abnormal side is always changed, and when the step S42 is executed, the controller of the first control part sends the real-time reading of the absolute value encoder of the first control part to the signal intercommunication device of the second control part through the signal intercommunication device every predetermined time value; when step S5 is executed, the controller of the second control unit controls the driving machine to operate at predetermined intervals, so that the normal-side rope pulling height is maintained to be the same as the abnormal-side rope pulling height.
In a word, the utility model adopts the balance structure of the balance weight, so that the lifting of the pull rope is very easy, a worker with smaller force can easily lift the pull rope, and the pull rope on the other side also follows the lifting, thus the lifting control of the whole safety door pull rope can be easily completed by only one person.
Embodiment two: as shown in fig. 1 to 3, which are only one embodiment of the present utility model, in the first embodiment, in a safety door lifting control method of the present utility model,
when executing step S3, it is determined whether the absolute value encoder reading of the first control portion has changed and the change value is greater than a predetermined threshold, and if yes, step S4 is executed.
That is, the pull rope on the abnormal side needs to satisfy enough displacement distance, so that the pull rope is pushed to lift by a worker, the normal side responds to the synchronous lifting, the rope is prevented from being blown by wind force when the motor fails, and the normal side also responds to the phenomenon.
In step S5, specifically, the following steps are performed:
s51: the controller of the second control part judges whether the reading of the absolute value encoder of the first control part is larger than the reading of the absolute value encoder of the second control part, if yes, the step S52 is executed; otherwise, executing step S53;
s52: the controller of the second control part drives the driving machine to rotate forward, so that the reading of the absolute value encoder of the second control part is the same as that of the absolute value encoder of the first control part;
s53: the controller of the second control part drives the driving machine to reversely rotate, so that the absolute value encoder reading of the second control part is the same as the absolute value encoder reading of the first control part.
The encoder reads out and increases to indicate that the pull rope rises, and the driving machine rotates positively to drive the pull rope to rise; the controller of the second control part can judge whether the pull rope on the abnormal side ascends or descends according to the change of the reading of the absolute value encoder of the first control part, so that the driving machine on the normal side is controlled to rotate positively or reversely, and the height of the pull rope on the normal side is synchronous with the height of the pull rope on the abnormal side.
It should be noted that the lifting column 2 is provided with a rotating roller 22, the rotating roller 22 is provided with a driving belt 23, one end of the driving belt 23 is connected with the sliding block 21, and one end of the driving belt 23, which is far away from the sliding block 21, is connected with the upright column 1.
The sliding block 21 can slide along the lifting column 2, the rotating roller 22 is non-autonomous, the rotating power source of the rotating roller 22 is from lifting of the lifting column 2, when the driving machine 11 drives the lifting column 2 to lift, the upright column 1 descends relative to the lifting column 2, so that one end of the driving belt 23 connected with the upright column 1 moves downwards relative to the lifting column 2, and then the sliding block 21 naturally ascends relative to the lifting column 2 under the driving of the driving belt 23.
The slider 21 is connected to the end of the pulling rope 3, so that the pulling rope 3 has two stages of ascending when the driving machine 1 drives the ascending and descending column 2 to ascend.
In this way, the two-stage lifting structure is utilized to lift the pull rope 3 to finish the door opening and closing of the shielding door structure, and the lifting of the lifting column 2 is provided with the balance weight 13 to balance the weight, so that the driving machine 11 can drive the pull rope 3 to lift at a larger lifting height only by small power, and the energy-saving effect is good; the stay cord 3 rises and is convenient for the passenger to get on and off the train, and the stay cord descends and can effectively prevent personnel from falling off the platform, and the security is high.
Of course, an insulating shielding layer is arranged on the outer side of the pull rope 2; the safety of personnel is ensured when the pull rope is lifted manually at the fault side.
The safety door lifting control method has high feasibility, after the motor at one side fails, through signal intercommunication between the two upright posts, when the pull rope is manually lifted at one side of the failure, the motor at the other side correspondingly rotates, so that the safety door is synchronously lifted, and emergency lifting control can be easily carried out on the failure safety door by only one person, and the control efficiency is high.
The present utility model is not limited to the above-described specific embodiments, and various modifications and variations are possible.
