Description
Technical Field
The utility model relates to an elevator travel switch field specifically is an elevator magnetic induction safety touch panel switch.
Background
The safety touch panel is a near-door safety protection device for an elevator, and is an electromechanical integrated door-closing anti-clamping safety device. The safety contact plate belongs to a soft door on an elevator car door, and when the elevator car senses an object in the door closing process, a limit switch connected to the near door can give a door opening signal to the control cabinet. The elevator is opened, thereby achieving the effect of not hurting people and not hurting objects.
At present, partial passenger elevators, a plurality of freight elevators, sundry elevators and old elevators in China still use safety contact plates to match with travel switches to form an anti-pinch device when the elevators are closed.
As shown in fig. 1, the conventional process switch is of a mechanical type, and has the following problems:
1. the safe touch plate 1 is not deep enough to trigger the travel switch, can trigger the travel switch within 30-60mm, and has slow response;
2. the safety contact plate 1 is pressed into a door, and the micro travel switch pressure lever 2 is easy to deform and possibly cause travel switch scrap due to too much pressing of the safety contact plate 1;
3. the long-term use of multiple extrusion easily causes fatigue deformation of the compression bar 2 of the travel switch, and the time-out safety triggering is insensitive and often needs to be maintained;
4. the installation process is not easy to debug;
5. the maintenance difficulty is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an elevator magnetic induction safety touch panel switch.
The utility model provides a technical scheme as follows that above-mentioned technical problem took:
the utility model provides an elevator magnetic induction safety touch panel switch, includes limit switch, magnet 4 and installing support 3, be equipped with tongue tube 5 in the limit switch, limit switch fixes in the elevator door, magnet 4 passes through installing support 3 to be fixed on safety touch panel 1, the mounting height of magnet 4 is corresponding with limit switch's mounting height, be equipped with a plurality of through-holes on installing support 3, the through-hole is used for adjusting magnet 4 and limit switch's installation distance.
Preferably, the reed switch 5 can be replaced by a hall switch.
The utility model relates to an elevator magnetic induction safety touch panel switch adopts the magnetic induction trigger mechanism of non-contact, triggers sensitive swift, and long service life is not fragile, and safe and reliable has reduced the maintenance number of times of elevator, very big reduction the maintenance cost of elevator.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
Drawings
The present invention will be described in detail with reference to the accompanying drawings so that the above advantages of the present invention can be more clearly understood.
Fig. 1 is a schematic diagram of a prior art elevator limit switch;
fig. 2 is the utility model relates to an elevator magnetic induction safety touch panel switch's schematic diagram.
Detailed Description
The present invention will be described in detail with reference to the following specific embodiments.
As shown in fig. 2, an elevator magnetic induction safety touch panel switch comprises a limit switch, a magnet 4 and a mounting bracket 3, wherein a reed switch 5 is arranged in the limit switch, the limit switch is fixed in an elevator door, the magnet 4 is fixed on a safety touch panel 1 through the mounting bracket 3, the mounting height of the magnet 4 corresponds to that of the limit switch, a plurality of through holes are formed in the mounting bracket 3, and the through holes are used for adjusting the mounting distance between the magnet 4 and the limit switch. When the elevator is used and the elevator door is closed, the safety contact plate 1 is contacted with the barrier and moves backwards, so that the magnet 4 is close to the reed pipe 5 in the limit switch, and the metal contact in the reed pipe 5 is triggered to give a door opening signal to the control cabinet. The elevator is opened, thereby achieving the effect of not hurting people and not hurting objects. The installation distance between the magnet 4 and the reed pipe 5 is adjusted through the installation support 3, and the trigger stroke is adjusted.
The reed switch 5 is typically made of two soft magnetic materials with metal reed contacts that open when not magnetically. These reed contacts are enclosed in a glass tube filled with inert gas (e.g., neon, helium, etc.) or vacuum, and the ends of the parallel enclosed reed contacts in the glass tube are overlapped and spaced apart or in contact with each other to form normally open or normally closed contacts of the switch. The reed switch 5 has simple structure, small volume, high speed and long service life compared with a common mechanical switch; compared with an electronic switch, the electronic switch has the characteristics of strong load impact resistance and the like, and has high working reliability.
Preferably, the reed switch 5 can be replaced by a hall switch.
The reed switches 5 have the advantage of being small and lightweight, which makes them easy to install and unobtrusive. Because the operation switch is small in size, a complex cam or a crank is not needed, the metal fatigue phenomenon cannot occur, and the almost infinite service life is guaranteed. And can be installed in a limited space.
The reed switch and suitable magnet 4 are inexpensive and readily available. The reed switch 5 is mainly a non-contact sealed switch. The switch component of the magnetic reed switch is sealed in inert gas and is not in contact with the external environment, so that the oxidation and carbonization of the contact caused by contact sparks in the opening and closing processes of the contact are greatly reduced. And prevents the erosion of foreign matters such as external steam and dust to the contact points. The service life is long.
The reed is thin and short, has higher natural frequency, improves the on-off speed of the contact, and has 5-10 times faster switching speed than a common electromagnetic relay.
The utility model relates to an elevator magnetic induction safety touch panel switch adopts the magnetic induction trigger mechanism of non-contact, triggers sensitive swift, and long service life is not fragile, and safe and reliable has reduced the maintenance number of times of elevator, very big reduction the maintenance cost of elevator.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
