Abstract
The utility model discloses a kind of elevator governor, comprise base, described base is provided with velocity limiter main body, the top of described base be provided with can relatively its vertically move, the upper beam that is connected with elevator wire rope; The side of described base is provided with the first switch, and can trigger described first switch in the process that moves down of described upper beam, described velocity limiter main body is also provided with the second switch triggered that re-packs by described velocity limiter main body; Described first switch and second switch are all electrically connected with the safety return circuit of elevator, and described first switch and second switch are flame-proof switch.The safe operation of elevator can not only be ensured in the process of or wire cable rupture descending at elevator overspeed by velocity limiter, simultaneously by design two pieces of adapter plates, flame-proof switch is placed on the relevant position of velocity limiter, velocity limiter is applicable in the environment of full explosive substance.
Description
Technical field
The utility model relate to a kind of elevator governor, belongs to elevator safety technical field.
Background technology
as elevator safety parts, velocity limiter has indispensable effect.Velocity limiter, as the term suggests be the parts of restriction elevator speed, when elevator downstream rate exceedes velocity limiter setting terminal speed, step switch is action cut off first, and then the position official post safety tongs link gear action to cause because of velocity contrast, thus make safety tongs and the action of each several part step switch thereof, force car to slow down until stop, so the quality of velocity limiter directly affects the safety that elevator runs.Because of the difference in elevator work bad border, the requirement of velocity limiter is also not quite similar, for example (,) full explosive substance bad border, just need to carry out explosion-proof process to each action position of elevator, produce to prevent any type of spark.And the technological processing for explosion protection feature also imperfection of current velocity limiter, once elevator overspeed or speed limiter wire rope fracture, the grazing between any metal parts just likely bursts out Mars, thus increases the possibility of blasting.
Utility model content
technical problem to be solved in the utility model is to provide a kind of elevator governor, the safe operation of elevator can not only be ensured in the process of or wire cable rupture descending at elevator overspeed by velocity limiter, simultaneously by design two pieces of adapter plates, flame-proof switch is placed on the relevant position of velocity limiter, velocity limiter is applicable in the environment of full explosive substance.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of elevator governor, comprises base, described base is provided with velocity limiter main body, the top of described base be provided with can relatively its vertically move, the upper beam that is connected with elevator wire rope; The side of described base is provided with the first switch, and can trigger described first switch in the process that moves down of described upper beam, described velocity limiter main body is also provided with the second switch triggered that re-packs by described velocity limiter main body; Described first switch and second switch are all electrically connected with the safety return circuit of elevator, and described first switch and second switch are flame-proof switch.
Aforesaid a kind of elevator governor, is characterized in that: described base is provided with two guide rods, and described upper beam can move up and down along described guide rod respect thereto.
Aforesaid a kind of elevator governor, is characterized in that: described first switch is fixed on the side of described base by the first switch installation board.
Aforesaid a kind of elevator governor, is characterized in that: described second switch is fixed in described velocity limiter main body by second switch adapter plate.
Aforesaid a kind of elevator governor, is characterized in that: described upper beam is also fixed with pouring weight.
The beneficial effects of the utility model are: by installing two switches be electrically connected with the safety return circuit of elevator, exceed the speed limit in descending process at lift car, the triggering second switch that re-packs of velocity limiter main body, cut off safety return circuit, and the velocity contrast of car and velocity limiter inspires safety tongs action, car is forced to slow down until stop, when elevator wire rope ruptures, upper beam loses pulling force and falls, the first switch is triggered in the process fallen, and then force car to slow down until stop by the safety return circuit of elevator, and by adopting flame-proof switch, velocity limiter is enable to be applicable in the environment of full explosive substance, improve the safety of use.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of elevator governor of the utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of elevator governor, comprises base 1, and described base 1 is provided with velocity limiter main body 2, the top of described base 1 be provided with can relatively its vertically move, the upper beam 3 that is connected with elevator wire rope; The side of described base 1 is provided with the first switch 5, and can trigger described first switch 5 in the process that moves down of described upper beam 3, described velocity limiter main body 2 is also provided with the second switch 6 of 7 triggerings that re-pack by described velocity limiter main body 2; Described first switch 5 and second switch 6 are all electrically connected with the safety tongs of elevator,
By installing two switches be electrically connected with elevator safety loop, exceed the speed limit in descending process at lift car, the 7 triggering second switches 6 that re-pack of velocity limiter main body 2, by cutting off the safety return circuit of elevator, and the velocity contrast of car and velocity limiter inspires safety tongs action, car is forced to slow down until stop, when elevator wire rope ruptures, upper beam 3 loses pulling force and falls, in the process fallen, trigger the first switch 5, by the safety return circuit cutting off elevator, all electric elements of elevator cannot be worked, cause elevator to run.In the present embodiment, first switch 5 is fixed on the side of described base 1 by the first switch installation board 8, second switch 6 is fixed in described velocity limiter main body 2 by second switch adapter plate 9, and described first switch 5 and second switch 6 are flame-proof switch, by adopting flame-proof switch, velocity limiter is enable to be applicable to, in the environment of full explosive substance, improve the safety of use.
Described base 1 is provided with two guide rods 4, described upper beam 3 can move up and down along described guide rod 4 respect thereto 1.
Described upper beam 3 is also fixed with pouring weight 10, avoids occurring because of the friction force between upper beam and guide rod 4 when wire cable rupture and cannot be descending, cause triggering elevator safety loop and causing safety misadventure.
In sum, a kind of elevator governor that the utility model provides, the safe operation of elevator can not only be ensured in the process of or wire cable rupture descending at elevator overspeed by velocity limiter, simultaneously by design two pieces of adapter plates, flame-proof switch is placed on the relevant position of velocity limiter, velocity limiter is applicable in the environment of full explosive substance.
More than show and describe groundwork of the present utility model, principal character and advantage.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
