Ladder lands and contacts in a flash with ground, the impulsive force of human body is reached maximum, causes casualties；Current most of elevator is adopted
Using mechanical fall protection equipment, not only excessively rapid in the process of stopping of stopping, in easily causing car, there is collision sedan-chair in passenger
Railway carriage or compartment wall damages, and existing mechanical protecting device many employings hydraulic spring grease cup buffer, liquid after increasing with the working time
Pressing spring buffer there will be oil leakage phenomenon, affects the normal work of hydraulic spring grease cup buffer, and oil spill also can give place
Bring the impact in terms of hygienic environment-protecting, and need the most frequently to overhaul, bring trouble to use, as maintenance occurs
Not in time, the inefficacy of fall protection equipment can be caused, not reach the effect of protection.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides one maintenance convenient, improves the elevator peace of safety
Total system.
This utility model solves its technical problem and be the technical scheme is that
A kind of elevator safety system, including car, lift well, hawser, controller, described car floor is provided with buffering
Layer, described cushion both sides have groove, are provided with telescopic hydraulic bar in described groove, and described telescopic hydraulic bar external part connects
Having brake shoes, be provided with the first electric magnet bottom described cushion, the side of described first electric magnet is provided with acceleration of gravity
Monitoring device；Described lift well borehole wall both sides are provided with frictional layer, and shaft bottom is provided with the second electromagnet, described first electric magnet,
Second electromagnet, hydraulically extensible bar are connected with controller, and described acceleration of gravity monitoring device access controller, motor loses
When fracture occur in power or hawser, car starts tenesmus, and described acceleration of gravity monitoring device monitors acceleration of gravity and exceeds
Normal value, makes hydraulically extensible bar work by controller, and brake shoes pushes to the lift well borehole wall, simultaneously the first electric magnet, second
Electric magnet is energized, and produces mutual expelling force, slows down decrease speed.
As a preference, described cushion is provided with electro-magnetic screen layer, it is to avoid to the electronic devices and components in car
Produce electromagnetic interference.
As a preference, being provided with interlayer in described car, described interlayer is built with spring pad, when tenesmus occurs
Time, reduce the collision injury in car.
As a preference, described first electric magnet and the second electric magnet are circle and have hole in centre, institute
Stating the first electric magnet and the second electric magnet is arranged on and is set with on spring steel column, steel column may pass through hole, when the first electric magnet and
When the second mutually exclusive power of electric magnet is excessive, weaken repulsive force by spring, it is to avoid directly to steel column effect, cause steel column to damage
Bad.
As a preference, described lift well borehole wall lower end is provided with curved plate, strengthens the friction of the borehole wall further
Power.
The beneficial effects of the utility model are: in this elevator safety system, acceleration of gravity monitoring device monitors gravity and adds
Speed, by controller make telescopic hydraulic bar promote brake shoes to the lift well borehole wall move, by with wall friction layer effect, subtract
Slow lapse rate, the first electric magnet and the second electric magnet are energized by controller simultaneously, produce the magnetic pole repulsive force of identical polar again
Once slowing down cage descending speed, this elevator safety system provides two kinds of deceleration measures, makes moderating process more steady, reduces
The cost of overhaul, adds the reliability of elevator safety system, and the spring pad interlayer being installed in car avoids passenger
Be collided injury, makes the security performance of elevator be improved.
