Abstract
The utility model discloses a non-contact type speed-reduction signal sensing device of a translational-type astronomical dome, and the device consists of a magnet steel and a switching signal apparatus, wherein the magnet steel is fixed on a motion part of the moving astronomical dome, and the switching signal apparatus is fixed at a side of a rail of the moving astronomical dome and is closed through the magnetic force of the magnet steel. The switching signal apparatus at least consists of a wiring plate and three reed pipes, wherein the three reed pipes are respectively arranged on the wiring plate, are in parallel connection, and are respectively in a disconnection state. The input and output ends of each reed pipe are respectively provided with a lead wire. According to the utility model, the non-contact type device is designed through a magnet-steel absorption mode, has no motion part, does not generate mechanical touch and impact, and is long in service life. The reed pipes serve as the key parts, and the switching element of each reed pipe is sealed in an inert gas in an airtight mode, is separated from the outside, and is long in working life.
Description
Technical field
The utility model relates to the contactless signal to reduce the speed sensing device of a kind of parallel-moving type astronomical dome.
Background technology
At present, parallel-moving type astronomical dome signal to reduce the speed sensing device all uses the mechanical contact limit switch, spacing and stop signal after putting in place as the parallel-moving type astronomical dome, its shortcoming is: after 1, dome touches the mechanical type limit switch, still there is higher speed, can not stop immediately, thereby produce overshoot, easily cause mechanical shock and equipment impaired; 2, the mechanical contact limit switch is touched ability generation effect because needs are mechanical, so the life-span is low.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of parallel-moving type astronomical dome contactless signal to reduce the speed sensing device, has guaranteed that the parallel-moving type astronomical dome steadily stops, and has solved overshooting problem, has eliminated mechanical shock.
For achieving the above object, the contactless signal to reduce the speed sensing device of a kind of parallel-moving type astronomical dome described in the utility model, by being fixed on magnet steel on mobile astronomical dome motion parts and being fixed on mobile astronomical dome track one side and the switching signal device of magnetic force closure by magnet steel.
Preferably, described switching signal device is at least by wiring plate, and is arranged on be connected in parallel mode and three tongue tubes in off-state of employing on wiring plate and forms, and input and the output of described three tongue tubes all go between.
Preferably, also comprise a water-proof sealing box, described wiring plate and three tongue tubes are placed in described closed enclosure.
Preferably, described closed enclosure is plastic casing.
The beneficial effects of the utility model are:
1, the utility model designs a kind of contactless device by the magnet steel suction type, and movement-less part can not produce the machinery touching and impact, and the life-span is long; Tongue tube is as one of critical component, and its switch element is hermetically sealed within inert gas, be hedged off from the outer world, and long working life;
2, the relative position of magnet steel and plastic casing is suitable, neither can scratch owing to crossing near the generation, also not can due to cross long-range guided missile cause reed switch contact can't adhesive.
The accompanying drawing explanation
Fig. 1 is the layout schematic diagram of the described magnet steel of the utility model embodiment;
Fig. 2 is the end view of the described switching signal device of the utility model embodiment;
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1-Figure 3, the contactless signal to reduce the speed sensing device of the described a kind of parallel-moving type astronomical dome of the utility model embodiment, by being fixed on magnet steel on mobile astronomical dome motion parts 54 and being fixed on mobile astronomical dome track one side and the switching signal device of magnetic force closure by magnet steel.
Embodiment is further described: described switching signal device is at least by wiring plate 1, and be arranged on be connected in parallel mode and three tongue tubes in off-state 2 of employing on wiring plate and form, input and the output of described three tongue tubes all go between.Also comprise a waterproof plastic closed enclosure 3, use electric drill to punch on its base plate and side plate, quantity is respectively 2 and 1, is used separately as permanent wiring plate and lead-in wire use, use 3 tongue tube parallel connections to be welded on wiring plate, wiring plate is fixed by screws on the plastic casing base plate.
During use, plastic casing is fixed by screws in mobile dome track one side, with parallel track; At mobile astronomical dome motion parts, select a suitable position to fix magnet steel, the distance of magnet steel and plastic casing is adjusted to effectively adhesive tongue tube, till can not producing touching again simultaneously.When magnet steel process plastic casing top, under the effect of magnetic field force, three reeds in tongue tube are magnetized and attract each other, produce contact, the circuit turn-on that node is connected, thus export a switching value signal, guarantee that portable astronomical dome steadily stops, and has eliminated impact.
Above; it is only preferred embodiment of the present utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
