According to the principle of like poles repelling each other, a force is applied by the device during the whole falling process of the elevator, so that no huge impact force is generated when the elevator falls, the harm is reduced as much as possible, and the safety of the elevator is increased by simply reforming the present elevator.
Description
Technical field
The utility model relates to the elevator technology field, more particularly, relates to a kind of device that prevents that elevator from falling suddenly.
Background technology
The basic structure of elevator is, in the vertical elevator hoistways, places a car moving up and down, and lift shaft enclosure is equipped with guide rail, with moving of guide rail restriction car on the car, and the support of car and move and be generally traction-type.Traction elevator generally is made up of hoistway and machine room, running part, up-down part, control part and safety device five parts.Hoistway surrounds a finite space that holds lift car and counterweight by leg, top board and pit; Have entry and exit at each stop; Machine room is arranged on the top of hoistway; Be used for installing towing machine, automatically controlled screen, velocity limiter etc., pit generally gos deep into ground, is used to install energy disperser, velocity limiter, steel wire rope stretching device; Running part is a towing machine, mainly is made up of electrical motor and steel rope, generally is installed in the top of machine room, and it is through rope traction car and counterweight; The lifting unit branch comprises car, counterweight and guide rail; Safety device is made up of velocity limiter and energy disperser, and velocity limiter is the equipment of control car speed, when car reaches capacity speed; The car velocity limiter begins action, and acts on and force it to clamp guide rail on the safety tongs, checks car; Energy disperser is the last safety guard-safeguard of elevator, and it is installed in the elevator hoistways pit, be positioned at car and counterweight under; In elevator moves up or down; When making car surmount the terminal stop owing to wire cable rupture, brake sticking brake power are not enough or control system is malfunctioning, energy disperser then plays buffer action, avoids elevator to hit the end or rushes to summit.
The working process of elevator is to drag steel rope through the motor drives towing machine car of elevator is moved along the guide rail on the lift shaft enclosure is upper and lower; The frame mid portion of car top is equipped with pulley base and pulley; Because steel rope is walked around this pulley and is stood flexural deformation for a long time; If steel rope ruptures when bending, will cause used during elevator falling and cause major accident.The elevator hoistways pit generally all is provided with buffer protection device for this reason; The fender guard that uses at present mainly is at fixing several groups of springs of elevator hoistways pit or hydraulic ram; When used during elevator falling; Antagonistic force through spring or hydraulic ram plays buffer action, sort buffer power weak effect, and occur resonance effect easily and cause more serious consequence.The fender guard that also has is a brake equipment, when used during elevator falling, suddenly to the elevator application of force, though can stop elevator to descend, suddenly stressedly also can damage personnel in the elevator.
Summary of the invention
The utility model technical matters to be solved is that a kind of device that prevents used during elevator falling is provided.
In order to address the above problem, the utility model provides a kind of device that prevents used during elevator falling, comprises car and hoistway; In the car bottom corresponding pole plate down is set, an iron prop is set in hoistway, bottom crown, SCM system, velocity measuring device and electric charge feeding mechanism are set at well pit; Said velocity measuring device is connected with SCM system; Said SCM system is connected with electric charge feeding mechanism input port, and said electric charge feeding mechanism delivery port is connected with iron prop and bottom crown, and said iron prop is connected through movable annulus with following corresponding pole plate; Bottom crown is with down corresponding pole plate size is identical, and the position is vertically opposite and have a like charges.
The effect of iron prop is equivalent to lead, and iron prop is with corresponding pole plate is through movable annulus series connection down, and when car moved up and down, annulus moved up and down on iron prop thereupon.Electric charge feeding mechanism delivery port is connected with following utmost point respective panels with bottom crown, and bottom crown has like charges with following utmost point respective panels when making work.
Bottom crown is identical with the area of the following corresponding pole plate of lift car lower surface, S=3.6
.Fill electricity time with when two pole plates, can regard a uniform electric field as between two pole plates, and two pole plates are band like charges, then have repulsion between them.Bottom crown is fixed on the ground of well pit, transfixion.And lower surface and elevator that following corresponding pole plate is installed in lift car move together.When elevator moves downward, will receive a power that makes progress, along with the minimizing of distance, it is big that the Coulomb force can continue to become.Between corresponding pole plate and the elevator lower surface block size suitable insulation plastics can be set down, prevent to damage when the electric leakage situation from taking place.
As a preferred version, said SCM system is the MCS-51 micro controller system.The radical function of micro controller system is to accept the data that sensor transmits, and analyzes, and starts the electric charge feeding mechanism then, gives bottom crown and down corresponding pole plate charging.
As another preferred version, said velocity measuring device is infrared speed measuring device.Adopt infrared multimetering speed; Can confirm measure dot number voluntarily according to the height of elevator; When elevator descended above qualification speed, data measured was passed to micro controller system through sensor, and micro controller system is through analyzing; Judge the load carrying ability of elevator, the charge volume of confirming two pole plates is to guarantee the landing of elevator safety actv..
The electric charge feeding mechanism is that the power supply of this device is a storage battery to bottom crown and the following electrically-charged device of corresponding pole plate.The main cause that elevator accident takes place is that the elevator supply system cuts off the power supply suddenly, influenced by this in order to prevent the electric charge feeding mechanism, and we adopt independently storage battery power supply.Under normal circumstances be that household electrical charges a battery, between storage battery and pole plate, also have voltage transformer, the electricity that storage battery is sent carries out high-voltage transforming, makes the quantity of electric charge of pole plate band more.
The advantage of the utility model is, the principle that polarity of the same race is repelled is mutually used in (1), and whole process application of force all can not produce enormous impact power when making used during elevator falling during to used during elevator falling, reduces injury as far as possible.(2) adopt infrared multimetering speed; When elevator descended above qualification speed, data measured was passed to micro controller system through sensor, and micro controller system is through analyzing; Judge the load carrying ability of elevator, the charge volume of confirming two pole plates is to guarantee the landing of elevator safety actv..(3) need simply transformed existing elevator and can improve its safety performance.
