Abstract
The present invention relates to a kind of additional brake of escalator methods of inspection, it is normal to start escalator, brake is kept to be in open configuration, directly disconnect host tachogenerator detection signal in switch board, so that anti-hypervelocity circuit supervision is abnormal to host tachometer signal, if additional brake generates effective action at this time, upcheck.The present invention quickly and effectively can effectively examine additional brake.
Description
Technical field
The present invention relates to escalator inspection technology field, more particularly to a kind of additional brake of escalator inspection party
Method.
Background technology
Additional brake is the important safety component of public traffic type escalator, especially in crowded public place
In be even more to play crucial protective effect.But there is no the tools for providing additional brake in standard GB/T 16899-1997
Body way of realization.Cause the additional brake working method of manufacturer's design varied the understanding difference of standard simultaneously.
Escalator has overspeed protection, i.e., its speed is more than 1.2 times of normal speed automatic stopping before, while is cut off certainly
Dynamic staircase power supply；And additional brake is acted before 1.4 times of normal speed.After overspeed protection must being shielded during inspection
It is able to verify that additional brake acts.In addition, escalator is also all provided with reverse protection, additional brake is exactly that one of which is inverse
To protective device.General escalator makes escalator stop fortune in antikinesis, by foundation brakes braking driving system
Row；And the escalator equipped with additional brake may be then foundation brakes and additional brake while act that staircase is protected to stop
Only run.
The existing method of inspection to additional brake is tested usually using counterweight as load, and whole process is very numerous
It is trivial, and there are certain danger.Therefore there is an urgent need for a kind of methods effectively examined to additional brake.
Invention content
The technical problems to be solved by the invention are to provide a kind of additional brake of escalator method of inspection, can quickly have
Effect effectively examines additional brake.
The technical solution adopted by the present invention to solve the technical problems is：A kind of additional brake of escalator is provided to examine
Method normally starts escalator, and brake is kept to be in open configuration, directly disconnects host tachogenerator inspection in switch board
Survey signal so that anti-hypervelocity circuit supervision, if additional brake generates effective action at this time, is examined to host tachometer signal exception
It tests and passes through.
It is further included during inspection and shields other reverse protection devices, removed motor power line, make output invalid, started automatic
Staircase is run up, and foundation brakes are opened, and jiggering runs to simulate the antikinesis during running up downwards, if this
When additional brake generate effective action, then upcheck.
Advantageous effect
As a result of above-mentioned technical solution, compared with prior art, the present invention having the following advantages that and actively imitating
Fruit：It does not need to increase load, and signal is detected using host tachogenerator in switch board is disconnected in whole process of the present invention
Simulate the situation of hypervelocity, using removing motor power line, by foundation brakes open downward jiggering operation mode simulate it is inverse
To the entire very convenient safety of checking procedure.
Specific embodiment
With reference to specific embodiment, the present invention is further explained.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
It was found by the inventors of the present invention that during antikinesis is usually escalator heavy duty uplink, due to weight
Power acts on, and leads to the downward car slipping of escalator.In view of actual conditions, escalator heavy duty, it is normal run up when, due to
The opposing torque of motor itself exceeds the speed limit to possibility very littles more than 1.2 times of normal speeds；And during heavy duty downlink, drive chain breaks
More than 2 times normal speeds are just likely to during the downward car slipping of chain.Downward car slipping when antikinesis is usually heavily loaded uplink.Therefore,
As long as additional brake acts in the case of ensureing two kinds, speed is less than volume when escalator being made effectively to stop, and being acted
1.4 times of constant speed degree, this additional brake stopping power are qualification.
No-load simulation test can be used in inspection, after normally starting escalator, staff keeps of brake
Open state detects signal by directly disconnecting host tachogenerator in switch board, and hypervelocity circuit supervision anti-in this way is surveyed to host
Whether fast abnormal signal, observing additional brake at this time can be with effective action, if can be passed through with effective action, additional brake
It examines.Whether the analogy method can test additional brake can be with effective action, whole process in the case where exceeding the speed limit
It is very convenient quick, and without worrying the problem of counterweight is fallen, there is no security risks.
When carrying out reverse protection inspection, analogy method is can also use, does not need to load.It is reverse that other are shielded first
Protective device removes motor power line, makes output invalid.Start escalator and run up that (practical escalator step is simultaneously
Not running), artificially foundation brakes are opened, to simulate the antikinesis during running up, observation is attached for downward jiggering operation
Add brake action whether effective action, if can be with effective action, additional brake passes through inspection.It is not difficult to find that examining
During reverse protection, practical escalator step and not running, therefore it is fool proof, and whole process is also very convenient.
Claims (2)
1. a kind of additional brake of escalator method of inspection, which is characterized in that normally start escalator, keep at brake
In open configuration, host tachogenerator detection signal in switch board is directly disconnected so that anti-hypervelocity circuit supervision is surveyed to host
Fast abnormal signal if additional brake generates effective action at this time, is upchecked.
2. the additional brake of escalator method of inspection according to claim 1, which is characterized in that screen is further included during inspection
Other reverse protection devices are covered, motor power line is removed, makes output invalid, starts escalator and runs up, by main brake
Device is opened, and jiggering runs to simulate the antikinesis during running up downwards, if additional brake generates effectively at this time
Action, then upcheck.
