Abstract
The invention discloses a multipurpose electromagnetic safety brake for a vertical elevator. The multipurpose electromagnetic safety brake is a safety protection device for the vertical elevator. A mechanical mode of an existing elevator overspeed preventing and falling preventing safety device is upgraded into an electromechanical mode, and the characteristics that sensitivity is high, the reaction speed is high, the protection purposes are wide, and the protection process is soft are achieved. The multipurpose electromagnetic safety brake is a multipurpose safety protection device, electromagnetic force generated by an electromagnet serves as braking power, under control of a control circuit with the corresponding control function, the protection functions such as the multiple purposes of an elevator car, soft decelerating, speed limiting and braking locking are achieved through the changes of the braking effect of a guide rail, and the multipurpose electromagnetic safety brake is suitable for elevator running preventing, mistaken starting preventing, mistaken door opening preventing, overspeed preventing, falling preventing, offside preventing and the like.
Description
Technical field
The present invention relates to a kind of safety guard of vertical lift elevator.
Background technology
At present; in the safety guard of existing vertical lift elevator; the velocity limiter of anti-hypervelocity, falling-proof safety device, safety tongs are mechanical type; also exist that sensitivity is low, speed of response is slow, the stiff shortcoming such as too quickly of brake; in concrete protection process; can leave the consequence that spirit is frightened and bodily injury is harmful to people, and protection content is single, other protection purposes can not be expanded to.
Summary of the invention
In order to the deficiency overcoming the anti-hypervelocity of existing elevator, falling-proof safety device exists; the invention provides a kind of vertical lift elevator high-mobility, multipurpose, wheeled vehicle Electromgnetic seat lock; this Electromgnetic seat lock is electromechanical; there is the features such as highly sensitive, speed of response fast, protection purposes is wide, protection process is soft; it, under the control circuit with respective control function controls, can realize deceleration to car multiple use and soft, speed limit and defencive functions such as stopping locking of stopping.
The technical solution adopted for the present invention to solve the technical problems is: the present invention adopts the electromagnetic force of electromagnet generation as braking effort; under the control circuit with respective control function controls; by changing the braking action of guide rail; realize slowing down to the deceleration of car various ways and gradual variable, speed limit and constant speed, stop and stop locking and gradual variable and to stop defencive functions such as stopping locking, thus reach multi-purpose safety guard-safeguard and the soft object of protection process.
The invention has the beneficial effects as follows: upgrade to electromechanical safety device of the present invention by the mechanical safety device of the anti-hypervelocity of existing elevator, fall arrest; it has the features such as highly sensitive, speed of response fast, protection purposes is wide, protection process is soft, is applicable to multi-purpose safety protection apparatus for elevator.

Detailed description of the invention
Safety brake is arranged on respectively the appropriate location, the left and right sides of car cab, matches with two, left and right guide rail.As shown in Figure 1 and Figure 2.
In the embodiment shown in fig. 1, when after magnet coil (1) energising, at electromagnetic force (P
1) effect under, electromagnetic core magnetic pole (2) adhesive, simultaneously by electromagnetic force (P
1) be applied on the electromagnetic driven arm of force (3), by lever principle, electromagnetic force (P
1) through arm of force fulcrum shaft (5), skid resistance arm (6) becomes brake weight (P
2), at brake weight (P
2) effect under, friction lining (7) and guide rail (9) produce huge drag friction power, are clamped firmly by guide rail (9), thus reach decelerations, speed limit, stop and stop the object of locking car; Magnet coil (1) is under the control circuit with variable output function controls; produce the electromagnetic force (P) of variable; friction lining (6) and guide rail (8) is made to produce the drag friction power of variable; achieve the brake of gradual variable, thus reach brake and namely protect the object that process is soft.When after magnet coil (1) power-off, under the effect of retracing spring (4), each parts set back.Lock frame (8) is the fixed support of safety brake.
In the embodiment depicted in figure 2, when after magnet coil (1) energising, under the effect of electromagnetic force (P), electromagnetic core magnetic pole (2) and friction lining (6) activity through swing arm axle (5), with guide rail (8) adhesive, in electromagnetic core swing arm (3), under electromagnetic force (P) effect of electromagnetic core magnetic pole (2) and friction lining (6) and guide rail (8) formation closed magnetic circuit, friction lining (6) and guide rail (8) is made to produce huge drag friction power, guide rail (8) is clamped firmly, thus reach deceleration, speed limit, stop and stop locking the object of car, magnet coil (1) is under the control circuit with variable output function controls, produce the electromagnetic force (P) of variable, friction lining (6) and guide rail (8) is made to produce the drag friction power of variable, achieve the brake of gradual variable, thus reach brake and namely protect the object that process is soft.When after magnet coil (1) power-off, under the effect of retracing spring (4), each parts set back.Lock frame (7) is the fixed support of safety brake.Friction lining (6), can adopt the material that magnetic property is high, magnetic resistance is little to make.
