Abstract
The utility model discloses a kind of elevator that safety guard is housed, comprise lift car, elevator hoistways and fall induction installation, the wall of described elevator hoistways is provided with pore area, described pore area forms by multiple Kong Yi straight lines on wall arrange, the bottom in described hole is fixed with spring, spring connects steel bar, hole is outside equipped with can the closing appliance of switch, when closing appliance cuts out, closing appliance is blocked hole thus is plugged in hole by steel bar, when closing appliance is opened, closing appliance is removed from hole, thus steel bar is stretched out by the effect of spring, the unlatching of described closing appliance controls by falling induction installation, when falling induction installation and sensing that lift car falls, closing appliance is opened.When lift car falls, closing appliance can be opened by speed sensor, and steel bar can be stretched out by spring, is cut off by steel bar by cutting knife, thus reduces the speed of tenesmus.
Description
Technical field
The utility model relates to elevators field, more specifically, relates to a kind of elevator that safety guard is housed.
Background technology
Along with the raising day by day of people's living standard and the quickening of rhythm of life, modern more and more adds attention to quality of life.For this reason, skyscraper is equipped with one or more elevator bar none.Elevator is widely used in modern society's life already.
Elevator is absolutely necessary as a kind of vertical transportation instrument.And the safety of elevator more and more causes the concern of people, the accident of generation threatens the life security of people.Form elevator unsafe factor a lot, but wherein endanger maximum to be the falling accident of hoistway, directly to cause the injures and deaths of personnel.
How preventing the elevator that can control timely when elevator falls to fall, is one of problem anxious to be resolved at present.
Utility model content
The purpose of this utility model is, when lift car meet accident fall time, control to fall speed or prevention are fallen.
First the utility model provides a kind of elevator that safety guard is housed, comprise lift car, elevator hoistways and fall induction installation, the wall of described elevator hoistways is provided with pore area, described pore area forms by multiple Kong Yi straight lines on wall arrange, the bottom in described hole is fixed with spring, spring connects steel bar, hole is outside equipped with can the closing appliance of switch, when closing appliance cuts out, closing appliance is blocked hole thus is plugged in hole by steel bar, when closing appliance is opened, closing appliance is removed from hole, thus steel bar is stretched out by the effect of spring, the unlatching of described closing appliance controls by falling induction installation, when falling induction installation and sensing that lift car falls, closing appliance is opened.
The position of the bottom corresponding aperture of described lift car arranges cutting knife, for cutting described steel bar.Because the existence of tangent plane can be cut off rapidly, the sensation that blunt clashes into can not be produced, thus make the reduction of speed milder.
Described safety guard is provided with 3 ~ 10 pore areas.
Described pore area arranges along the direction of elevator or arranges a circle round elevator.
Described pore area is arranged at least three walls of elevator hoistways.
The described induction installation that falls is speed sensor, is installed on lift car.
In the device preventing from falling, important is not how to allow lift car stop, but how to allow elevator can stop within tolerance range people, and the potential energy that lift car is fallen by cut-out steel bar by the utility model is discharged in steel bar.Thus by the fastest mode and safest mode, the speed fallen by lift car reduces, thus ensure the safety of people in elevator.Described falling refers to that lift car exceeds command speed.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is the schematic diagram of the steel bar in hole when being cut.
Wherein, 1 is lift car, and 2 is wall, and 3 is pore area, and 4 is speed sensor, and 5 is elevator hoistways, and 6 is cutting knife, and 7 is hole, and 8 is steel bar, and 9 is spring, and 10 is closing appliance.
Detailed description of the invention
The utility model is further described below in conjunction with the drawings and specific embodiments.Unless stated otherwise, the utility model adopts reagent, equipment and method are conventional commercial reagent, equipment and the conventional method used of the art.
Embodiment 1
A kind of elevator that safety guard is housed is provided, comprise lift car 1, elevator hoistways 5 and fall induction installation, the wall 2 of described elevator hoistways 5 is provided with pore area 3, described pore area 3 is arranged by the multiple holes 7 on wall 2 and forms on a straight line, the bottom in described hole 7 is fixed with spring 9, spring 9 connects steel bar 8, hole 7 is outside equipped with can the closing appliance 10 of switch, when closing appliance 10 cuts out, closing appliance 10 is blocked hole 7 thus is plugged in hole 7 by steel bar 8, when closing appliance 10 is opened, closing appliance 10 is removed from hole 7, thus steel bar 8 is stretched out by the effect of spring 9, the unlatching of described closing appliance 10 controls by falling induction installation, when falling induction installation and sensing that lift car 1 falls, closing appliance 10 is opened, the position of the bottom corresponding aperture 7 of lift car 1 arranges cutting knife 6, for cutting described steel bar 8, safety guard is provided with 3 pore areas 3, pore area 3 is arranged along the direction of elevator, 3 pore areas 3 are arranged on three walls 2 of elevator hoistways 5, falling induction installation is speed sensor 4, is installed on lift car 1, when speed exceedes threshold values, falls induction installation and sends the automatic opening enclosed device 10 of signal.
As shown in figures 1 and 3, when falling, closing appliance 10 can be opened in downward landing, and then steel bar 8 is stretched out by spring 9, when lift car 1 is by steel bar 8, cuts off steel bar 8 by cutting knife 6, thus the potential energy release that will fall, underspeeding of effective and safe.
Embodiment 2
A kind of elevator that safety guard is housed is provided, comprise lift car 1, elevator hoistways 5 and fall induction installation, the wall 2 of described elevator hoistways 5 is provided with pore area 3, described pore area 3 is arranged by the multiple holes 7 on wall 2 and forms on a straight line, the bottom in described hole 7 is fixed with spring 9, spring 9 connects steel bar 8, hole 7 is outside equipped with can the closing appliance 10 of switch, when closing appliance 10 cuts out, closing appliance is blocked hole 7 thus is plugged in hole 7 by steel bar 8, when closing appliance 10 is opened, closing appliance 10 is removed from hole 7, thus steel bar 8 is stretched out by the effect of spring 9, the unlatching of described closing appliance 10 controls by falling induction installation, when falling induction installation and sensing that lift car 1 falls, closing appliance 10 is opened, the position of the bottom corresponding aperture 7 of lift car 1 arranges cutting knife 6, for cutting described steel bar 8, safety guard is provided with 3 pore areas 3, pore area 3 is arranged along the direction of elevator, 3 pore areas 3 are arranged on three walls 2 of elevator hoistways 5, falling induction installation is speed sensor 4, is installed on lift car 1.
