As shown in figure 1, this elevator overspeed protecting device 2 includes guide rail 21, leads boots 22 and speed monitoring sensor.
Described guide rail 21 and the mating surface led the mutual concavo-convex engaging gap cooperation of boots 22 and worked in coordination use magnetic conduction
Material, leads boots 22 and is fixedly installed on along the direction of moving towards of elevator hoistways on elevator hoistways inwall, and the correspondence of guide rail 21 leads the position of boots 22
Put and be fixedly installed on the outer wall of car 4, lead boots 22 provided with flexible sliding part 23 and brake shoe 24, stretch sliding part 23
Telescopic direction of the inside provided with magnet coil and flexible sliding part 23 faces the fit inside of guide rail 21 perpendicular to boots 22 are led
Face, brake shoe 24 is arranged on the fit inside face of guide rail 21 by flexible sliding part 23.
Described speed monitoring sensor includes displacement transducer and velocity sensor, and displacement transducer is arranged on elevator
In road, velocity sensor is arranged on car 4.
This elevator overspeed protecting device is arranged on elevator in use, when elevator starts, speed monitoring sensor is real-time
The translational speed of car 4 is fed back to elevator central processing unit, when the translational speed of speed monitoring sensor feedback car 4 is in journey
When in the range of the safe speed higher limit of sequence setting, the magnet coil inside the flexible sliding part 23 of central processing unit control makes to lead
Magnetic pole identical magnetic field is produced between rail 21 and the mating surface for leading the mutual concavo-convex engaging of boots 22, identical charges repel each other due to magnetic pole, therefore
Repulsive interaction realization in magnetic field is produced between the mating surface that bumps engage mutually in the lifting process of car 4 and leads boots 22 to leading on car 4
Rail 21 provides balance thrust in a balanced way and then realizes that the suspension of car 4 is oriented to, while this repulsive interaction, which is promoted, leads stretching on boots 22
Sliding part 23 drives brake shoe 24 brake shoe 24 is abutted on the medial surface for leading boots 22 to the movement away from the direction of guide rail 21
In the state away from guide rail 21；
When the translational speed of speed monitoring sensor feedback car 4 is in safe speed higher limit and the danger of program setting
During scope between speed limit value, the magnet coil inside the flexible sliding part 23 of central processing unit control makes guide rail 21 and led
The opposite magnetic field of magnetic pole is produced between the mating surface that bumps engage mutually of boots 22, there is a natural attraction between the sexes due to magnetic pole, therefore car 4 is lifted
During producing magnetic attraction force between the mating surface of concavo-convex engaging realizes that lead boots 22 provides equilibrium to the guide rail 21 on car 4 mutually
Balance suction, while this balance suction promotes and leads flexible sliding part 23 on boots 22 and drive brake shoe 24 to close to guide rail 21
Direction movement brake shoe 24 is abutted in the mating surface of guide rail 21 in the on-position for holding guide rail 21 tightly.
In order to improve reaction speed, ensure the timely and effective control in the moving process of lift car 4, entering for the present invention is used as
One step improvement project, the speed monitoring sensor of described overspeed protective device 2 also includes acceleration transducer, acceleration sensing
Device is electrically connected with the central processing unit of described electric control gear, and central processing unit is built-in with safe acceleration and dangerous acceleration
Higher limit.Timely and effective control elevator can be ensured by being monitored simultaneously by the translational speed and acceleration to lift car 4
The movement of car 4.
In order to further improve the effect for suspending and being oriented to magnetic brake, an improvement project, institute are entered as the present invention
The guide rail 21 stated is magnet structure or connects magnet coil composition electromagnet structure by magnetic conductive material mating surface.
This elevator overspeed protecting device can be applied not only to the elevator of vertical lift, can also be applied to all carry
In such as mine cage Lifting Convey equipment of vertical hoistway, and it is equally applicable for the oblique elevator with counterweight.
This elevator overspeed protecting device guide rail 21 and is led due to including guide rail 21, leading boots 22 and speed monitoring sensor
The mating surface that concavo-convex engaging gap coordinates and worked in coordination mutually of boots 22 uses magnetic conductive material, leads boots 22 provided with flexible cunning
Part 23 and brake shoe 24 are moved, telescopic direction of the inside of sliding part 23 of stretching provided with magnet coil and flexible sliding part 23
Perpendicular to boots 22 are led in face of the fit inside face of guide rail 21, brake shoe 24 is arranged in guide rail 21 by flexible sliding part 23
In the mating surface of side, therefore when the translational speed of car 4 is in the range of safe speed higher limit, inside the sliding part 23 that stretches
Magnet coil make guide rail 21 and lead boots 22 producing magnetic pole identical magnetic field between the mating surface of concavo-convex engaging realizes car 4 mutually
Suspension be oriented to, while brake shoe 24 be in away from guide rail 21 state, when car 4 translational speed be in the safe speed upper limit
When outside value, the magnet coil inside flexible sliding part 23 makes guide rail 21 and leads boots 22 mutually between the concavo-convex mating surface engaged
The opposite magnetic field of magnetic pole is produced, simultaneous retractable sliding part 23 drives brake shoe 24 to make braking to the movement close to the direction of guide rail 21
