Description
Technical field
The utility model relates to experimental provision field, in particular to a kind of used during elevator falling braking apparatus for demonstrating.
Background technology
At present, used during elevator falling accident is normally caused by electric power system fault, and when there is accident, because electric power system is destroyed, protection facility cannot normally use, and just causes the generation of tragedy.Frequent Accidents also makes to avoid used during elevator falling accident more and more to receive the concern of people how better.No matter be in Corporation R & D or the teaching in school; the experimental provision providing a kind of simulant elevator to fall can show that the drop event of elevator can help people to understand whole process well visually; thus the key issue be familiar with better in used during elevator falling, provide convenient for improving to the level of understanding of relevant issues, the protection facility of reliable design.
Utility model content
Technical problem to be solved in the utility model is, providing a kind of can fall and the experimental provision of braking procedure by simulant elevator.
Therefore, the technical solution of the utility model is as follows:
Used during elevator falling braking apparatus for demonstrating comprises base, vertical rod, lifting table and is arranged on pressure switch, weight, electromagnet, magnet, the control circuit on described lifting table, wherein:
Described vertical rod is vertically installed on described base, described lifting table to be set in described vertical rod and can to slide along described vertical rod, described weight is placed in described pressure switch, and described magnet to be arranged on described lifting table by a shell fragment and between described electromagnet and described vertical rod;
Described control circuit comprises battery, relay and pilot lamp, the coil KM of described pilot lamp, described relay and the series connection of described pressure switch, and described electromagnet is connected with the normally opened contact K of described relay, and described battery is used for powering for whole circuit;
Limit described lifting table by the friction force between itself and described vertical rod when described magnet adsorption is in described vertical rod to glide, when described lifting table is weightless, described pressure switch closes, and makes described electromagnet produce the magnetic force repelling described magnet.
In this technical scheme, at ordinary times by magnet adsorption in vertical rod, lifting table is fixed, now because weight is pressed in pressure switch, so pressure switch stays open, circuit disconnect; When needing demonstration, magnet is pulled up from vertical rod and is adsorbed on the iron core of electromagnet, now lifting table is along vertical rod free-falling after loosing one's grip, and weight weightlessness causes pressure switch to close, power on circuitry, the coil KM of relay obtains electric, normally opened contact K closes, and magnet flicks and makes magnet adsorption in vertical rod by electromagnet energising generation repulsion, and the friction force between magnet and vertical rod forces lifting table to stop falling, weight again compressive pressure switch makes pressure switch disconnect, thus lifting table can keep static.This apparatus for demonstrating can the falling and braking procedure of simulant elevator well, helps people to improve understanding to relevant issues, also can put for research and development the technology enlightenment that arrest systems provides certain more reliably.
Described used during elevator falling braking apparatus for demonstrating also comprises lifting rope, is connected to the top of described lifting table and described vertical rod.Lifting table is fixed further at ordinary times, more reliably with lifting rope.
Accompanying drawing explanation
Fig. 1 is the structural representation of the used during elevator falling braking apparatus for demonstrating according to the utility model embodiment;
Fig. 2 is the control principle drawing of the used during elevator falling braking apparatus for demonstrating according to the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, the used during elevator falling braking apparatus for demonstrating according to embodiment of the present utility model comprises base 1, vertical rod 2, lifting table 3 and is arranged on pressure switch 4, weight 5, electromagnet 6, magnet 7, the control circuit 8 on described lifting table 3, wherein:
Described vertical rod 2 is vertically installed on described base 1, described lifting table 3 to be set in described vertical rod 2 and can to slide along described vertical rod 2, described weight 5 is placed in described pressure switch 4, and described magnet 7 to be arranged on described lifting table 3 by a shell fragment 9 and between described electromagnet 6 and described vertical rod 2;
Described control circuit 8 comprises battery 10, relay and pilot lamp 12, coil KM and the described pressure switch 4 of described pilot lamp 12, described relay are connected, described electromagnet 6 is connected with the normally opened contact K1 of described relay, and described battery 10 is for powering for whole circuit;
Limit described lifting table 3 by the friction force between itself and described vertical rod 2 when described magnet 7 is adsorbed in described vertical rod 2 to glide, when described lifting table 3 is weightless, described pressure switch 4 closes, and makes described electromagnet 6 produce the magnetic force repelling described magnet 7.
In this technical scheme, be adsorbed in vertical rod 2 at ordinary times, be fixed magnet 7 lifting table 3, now because weight 5 is pressed in pressure switch 4, so pressure switch 4 stays open, circuit disconnects; When needing demonstration, magnet 7 is pulled up from vertical rod 2 and is adsorbed on the iron core of electromagnet 6, now lifting table 3 after loosing one's grip along vertical rod 2 free-falling, weight 5 weightlessness causes pressure switch 4 to close, power on circuitry, the coil KM of relay obtains electric, normally opened contact K1 closes, magnet 7 flicks and makes magnet 7 be adsorbed in vertical rod 2 by electromagnet 6 energising generation repulsion, friction force between magnet 7 and vertical rod 2 forces lifting table 3 to stop falling, weight 5 again compressive pressure switch 4 makes pressure switch 4 disconnect, thus lifting table 3 can keep static.This apparatus for demonstrating can the falling and braking procedure of simulant elevator well; help the understanding of people's raising to relevant issues; also can put arrest systems more reliably for research and development provides certain technology to enlighten; and whole system not power consumption at ordinary times; can economize energy well; elevator can guarantee there are enough power start safeguard measures when accident occurs according to such design, improves the reliability of whole system.
Described used during elevator falling braking apparatus for demonstrating also comprises lifting rope 11, is connected to the top of described lifting table 3 and described vertical rod 2.At ordinary times with lifting rope 11 fixing lifting table 3 further, more reliably.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is all included within scope of the present utility model.
