Description
Technical field
The present invention relates to the traction machine brake that a kind of elevator traction machine is used, particularly a kind of Intelligent self-checking surveys traction machine
Brake.
Background technology
Existing traction machine brake is nearly all to use brake scotch component to be interacted with braked wheel when using, to control
The rotation of traction machine.During brake scotch component and braked wheel obvolvent, the friction plate heating of brake scotch component is very fast, too late
If Shi Jiangwen, uninterrupted obvolvent, easily accelerates the damage of friction plate for a long time；And in traction machine environment mounted externally, ash
Dirt, impurity etc. are easily fallen on the braked wheel of traction machine, so as to influence the obvolvent between braked wheel and brake scotch component, obvolvent
During easily scratch braked wheel and Friction Disk Surface.And brake scotch component it is long-term incessantly with braked wheel obvolvent, separate,
So as to result in brake scotch component wear than more serious, the friction plate on brake scotch component is easy to damage, and its surface easily becomes
Smoother, braked wheel cohesive force is diminished so as to result in brake scotch component, it is difficult in time cause traction machine stalling, be this
Allow for detecting size of the brake scotch component to braked wheel cohesive force well.And existing friction plate structure is also closed not to the utmost
Reason, it is more complicated during installation, and brake scotch is inadequate to the active force of friction plate, it is difficult to connected well between guarantee.
In terms of comprehensive, the friction plate rate of decay of existing traction machine is fast, friction plate installs complicated, and the mill of friction plate
Damage situation is unable to timing monitoring.
The content of the invention
It is an object of the present invention to provide a kind of Intelligent self-checking surveys traction machine brake.The friction plate of the present invention damages speed
Degree is slow, friction plate installs simple, and the abrasion condition energy timing monitoring of friction plate.

Provided with substrate, substrate is provided with sensitive grid, and sensitive grid is connected with lead, and the lead other end is connected with controller, is set on sensitive grid
There is cover plate.
Beneficial effects of the present invention：Compared with prior art, the present invention is provided with air bag, when magnetic apparatus controls brake scotch group
When part is separated with braked wheel, brake arm applies pressure with block to air bag so that air bag compresses, and air is acted on from gas blow pipe head end
On braked wheel and I-shaped friction plate, cooling effect is carried out to friction plate and braked wheel, so as to reduce the abrasion speed of friction plate
Spend, and braked wheel and dust, impurity on I-shaped friction plate etc. can be will be attached to and blow away, it is to avoid it influences braked wheel and system
Obvolvent between dynamic watt component, it is to avoid dust, impurity etc. cause the damage of I-shaped friction plate, braked wheel；It is provided with brake scotch
The friction plate of I-shaped structure is caught in neck, neck, neck can fix I-shaped friction plate well, it is to avoid I-shaped friction
Moved after piece stress, while so that need not be fixed between brake scotch and I-shaped friction plate by screw so that rub
The installation of pad becomes fairly simple；It is provided with brake scotch surface and is put into pressure sensor in pit, pit and is caught in I-shaped
The projection of friction plate, one is more firm to connect between I-shaped friction plate and brake scotch, and the two I-shaped friction plate is to braking
The cohesive force of wheel can pass to pressure sensor by projection, and pressure sensor is again by the pressure transmission detected to control
Device, so that size of the brake scotch component to braked wheel cohesive force is detected well, so as to judge the abrasion feelings of I-shaped friction plate
Condition；Antifriction cleaning block is interval with braked wheel, the mutual frictional force between I-shaped friction plate and braked wheel is improved, when I-shaped rubs
When wherein 1 piece of pad or antifriction cleaning block is damaged, braked wheel can also be braked, improve the security performance of brake；
Flexible member in the pressure sensor of the present invention deforms after being pressurized, so as to cause strain effect, is formed by sensitive grid
Change-over circuit the change in resistance in strain effect is converted into voltage signal, and pass to controller, controller passes through voltage
Contrast, judges whether the cohesive force of I-shaped friction plate is in normal condition.The pressure sensor accuracy of detection is high, detection range
Extensively, and application condition is small.In the lead-out groove that the lead embedment brake scotch of pressure sensor is provided with, it is to avoid lead is by brake scotch
It is easily damaged with after the effect of I-shaped friction plate pressure.In summary, brake of the invention has that friction disc wear speed is slow, rub
Pad is easily installed, the features such as friction disc wear situation can be monitored in real time.
