Background technique
Traction machine is a kind of dynamic power machine, is generally used for elevator, and the brake apparatus of traction machine is to guarantee elevator safety operation
Basic device, compared with the traction machine of stereo garage, the brake of the dedicated traction machine of escalator requires higher, and structure also compares
More complex, such cost is relatively high, safeguards relatively difficult.It is generally used for the friction disc wear instruction of detection brake wear situation
Stick is only applicable to manually check, and can not accomplish to detect automatically, since traction machine brake is mounted on inside traction machine, maintenance personnel
It safeguards that observation interval is longer, is unfavorable for observing due to there is unusual service condition and wearing than faster brake, may cause
Brake wear is not found to the limit, so that brake disc surface be caused to wear, therefore a kind of intelligent dynamic staircase is dedicated drags
Drawing brake friction plate sensor is highly desirable.
Summary of the invention
For prior art defect, the invention patent provides a kind of dedicated traction machine brake of intelligent escalator, packet
Include when providing the friction disc wear of brake a kind of to the limit can automatic alarm and friction plate sensing safe and convenient, practical
Device.

The groove inner wall for filling the main body of seat is equipped with and brakes the consistent annular via of disk shape, and scheme makes motor exist using the above structure
The pinching action of brake arm realizes braking of the brake(-holder) block to brake disc under power blackout situation.
The invention patent is further arranged to: the support member of microswitch, support member and system are equipped with inside brake disc
Moving plate is detachably connected.
The invention patent is further arranged to: when the friction plate does not arrive limiting condition, the stroke quilt of microswitch
Compression, switch are in close state, and provide normally closed signal.When friction disc wear is to the limit, moves to and pass outside friction plate pedestal
Sensor clamping piece is detached from, and so that microswitch is triggered, is provided switch opening signal, which can also start brake by force,
Brake wear accident is avoided to occur.
Detailed description of the invention
Fig. 1 is the brake arm component diagram of the invention patent embodiment.
Fig. 2 is the friction plate assembly schematic diagram of the invention patent embodiment.
Wherein appended drawing reference includes:
1 left 24 elastic cylindrical pin of right 3 friction plate assembly of brake arm of brake arm, 5 disk spring
6 microswitch, 7 brake disc, 8 split pin 9 fluting 10 hole cylinder pin of tapered end positioning screw
11 friction plate pedestal, 12 friction plate, 13 friction plate sensor, 14 sensor clamping piece
Specific embodiment
It is attached below in conjunction with what is provided to be more clear the invention patent technical problem to be solved and technical solution
Figure and embodiment, are further explained the invention patent and illustrate, the patent for explaining only the invention of specific descriptions herein,
But the scope of protection of the patent of the present invention is not limited to this.
As shown in Figure 1, a kind of dedicated traction machine brake of intelligent escalator, including left brake arm 1, right brake arm 2,
Friction plate assembly 3 and brake disc 7.The friction plate assembly 3 is mounted on described two brake arms 3 by elastic cylindrical pin 4 respectively
On 4, brake(-holder) block is all separately installed on described two brake arms 1 and 2, the upper end of described two brake arms 1 and 2 is equipped with dish
Shape spring 5 is cased with a connecting rod between the disk spring and couples brake arm both ends, under motor power blackout situation, brake
Effect is so that the pinching action of brake arm realizes brake(-holder) block to system.
Microswitch 6 is set to 7 hull outside of brake disc, and conducting wire is electrically connected with microswitch 6 and from 7 Sales body of brake disc
One end is pierced by.
Motor mount is fixed with split pin 8 after the other end of described two brake arms 1 and 2 is set with gasket
On.
5 portion of being limited of disk spring is blocked, therefore 5 normal condition of disk spring is compressive state, when friction plate 12 is worn
When to a certain extent, brake arm 1 or 2 is separated with brake disc 7, and disk spring just restores normal condition.
When friction plate does not arrive limiting condition, sensor clamping piece 14 is pressed on friction plate pedestal 11, microswitch 6
Stroke compressed, switch is in close state, and output voltage 0 provides normally closed signal.When friction disc wear is to the limit,
It moves to outside friction plate pedestal 11 and is detached from sensor clamping piece 14, microswitch 6 is made to be triggered, at this moment output voltage is high electricity
It is flat, warning circuit is connected in abnormal signal input electronic control unit, provides switch opening signal, this signal accesses traction machine control
System PLC is used to that the friction plate 12 is reminded to arrived ultimate life, replaceable.The signal can also start brake disc 7 by force,
7 abrasion accident of brake is avoided to occur.
