Under, cause unblock difficult, personnel are once trapped between shield door and car door, it is impossible to emergency escape, the thing for causing casualties
Therefore, while mechanical transmission mechanism also has that maintenance is difficult, is easily damaged.
The content of the invention
The purpose of this utility model is to provide a kind of improved locking and unlocking mechanism for half high shield door, and it can
Overcome unblock inconvenience, some shortcomings being easily damaged in prior art.
To achieve these goals, the technical solution of the utility model is：A kind of locking for half high shield door is conciliate
Latch mechanism, the sliding door that it is mainly included fixed door and is coordinated with fixed door, it is characterised in that：The upper and lower side of sliding door point
Movable guiding rail is not provided with, described movable guiding rail is arranged at the side of fixed door；The side of sliding door is connected with an AC servo
Motor, AC servomotor are connected with sliding door by a drive mechanism；The top of fixed door is provided with emergency stop switch, described
Emergency stop switch be connected with AC servomotor.
Preferably, described drive mechanism is gear and tooth bar, is provided with gear on the output shaft of AC servomotor,
The side of sliding door is provided with the tooth bar being engaged with gear.
Optionally, the side of sliding door is provided with an electric machine support, and described AC servomotor is arranged at electric machine support
On.
During use, in emergency situations, when needing to open sliding door, mechanical release need not be carried out, as long as pressing red anxious
Stop button, opening door operation can be completed with sliding door is pulled out, it is time saving and energy saving, it is that emergency escape wins valuable time.It is sliding
Dynamic door is locked and unlocking mechanism due to mechanical so that the structure of mechanical transmission mechanism is simpler, and service life is longer.
Description of the drawings
Structural representations of the Fig. 1 for one embodiment of this utility model.
Fig. 2 be Fig. 1 in A-A to structural representation.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Label in each accompanying drawing is expressed as follows：
1st, sliding door；2nd, fixed door；3rd, emergency stop switch；4th, gear；5th, tooth bar；6th, the AC servo of strap brake braking is electronic
Machine.
A kind of locking and unlocking mechanism for half high shield door described in the utility model, it mainly include fixed door and
The sliding door coordinated with fixed door, its difference with the prior art is：The upper and lower side of sliding door is respectively equipped with activity and leads
Rail, described movable guiding rail are arranged at the side of fixed door；The side of sliding door is connected with an AC servomotor, and exchange is watched
Take motor to be connected with sliding door by a drive mechanism；The top of fixed door is provided with emergency stop switch, described emergency stop switch with
AC servomotor is connected.
Preferably, described drive mechanism is gear and tooth bar, is provided with gear on the output shaft of AC servomotor,
The side of sliding door is provided with the tooth bar being engaged with gear, and under the cooperation of wheel and rack, sliding door can be along guide rail certainly
By sliding.
Optionally, the side of sliding door is provided with an electric machine support, and described AC servomotor is arranged at electric machine support
On, the height of electric machine support is 25-35cm.
Further, a difference in height is respectively present between the upper and lower side of the upper and lower side of sliding door and fixed door, it is high
The value of degree difference is 4-11cm；There is an installation gap between AC servomotor and sliding door, the size for installing gap is
3-7cm。
Optionally, described AC servomotor is the AC servomotor of strap brake braking.Using strap brake system
Dynamic AC servomotor, after sliding door closes the door closure, the skidding function of AC servomotor works, and slides
Door is locked motionless.When the state of emergency needs to open sliding door, red scram button is pressed, cut off AC servomotor
Power supply, the skidding function of AC servomotor do not work, and sliding door is in free state, now can be with handss
Shielding sliding door is easily pulled open, opening door operation is completed, escape purpose is reached.
In enforcement, on the basis of fixed door 2 is anchored at platform side, the upper-lower position of sliding door 1 be provided with movable guiding rail with
Fixed door 2 is linked together, and sliding door 1 can be moved back and forth on fixed door 2 under external force.The exchange of strap brake braking is watched
Take motor 6 to be fixed on electric machine support, gear 4, tooth bar 5 are housed on 6 output shaft of AC servomotor of strap brake braking
It is connected with sliding door 1, emergency stop switch 3 is fixed on the top of fixed door 2.
The AC servomotor 6 of strap brake braking passes through gear 4 and tooth bar 5 transfers power to sliding door 1, drives and slides
Dynamic door 1 is opened the door and is closed an action.When sliding door open the door and close action reach setting position when, the friendship of strap brake braking
Stream 6 stop motion of servomotor, the skidding function of the AC servomotor 6 of strap brake braking are worked, sliding door 1
It is locked stiff.
Under the state of emergency, when track train side needs to open sliding door, scram button 3 is pressed, scram button 3 is immediately
The power supply of the AC servomotor 6 of cut-out strap brake braking, the brake system of the AC servomotor 6 of strap brake braking
Dynamic function does not work, and sliding door 1 is in free state, now can easily pull open sliding door 1 with handss, complete opening door operation,
Reach escape purpose.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Assert that this utility model is embodied as being confined to above-mentioned these explanations.For the common skill of this utility model art
For art personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should
It is considered as belonging to protection domain of the present utility model.
