Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment one
Refer to Fig. 1 to Fig. 6, a kind of elevator pit cat ladder, comprise the two cat ladder side bars vertically be arranged in parallel, two cat ladder side bars wherein one be movable side bar 1, another root is fixing side bar 8, and this elevator pit cat ladder also comprises draw-in groove 2, cat ladder cross bar 3, bearing pin 4, switch 5, jam plate 6 and tapered end 7.Movable side bar 1 and fixing side bar 8 vertically be arranged in parallel, and many cat ladder cross bar 3 two ends be parallel to each other are rotatably connected between movable side bar 1 and fixing side bar 8 respectively by bearing pin 4.Fixing side bar 8 is fixed on well enclosure, and movable side bar 1 launches away from fixing side bar 8 by cat ladder cross bar 3 or closes up near fixing side bar 8.
Movable side bar 1, fixing side bar 8 and many cat ladder cross bars 3 constitute the parallelogram sturcutre of Foldable and deformable, therefore, it is possible to the folding and retraction of pit ladder.
This elevator pit cat ladder has deployed condition and close up state, and movable side bar 1 is supported on draw-in groove 2 away from fixing side bar 8 in the deployed state, upwards rotates and merges with fixing side bar 8 and draw close closing up under state movable side bar 1 along cat ladder cross bar 3.
Draw-in groove 2 is fixedly installed on well enclosure with movable support side bar 1.The quantity of draw-in groove 2 is multiple, and multiple draw-in groove 2 is vertically disposed on well enclosure, and movable side bar 1 has and multiple draw-in groove 2 feet 11 one to one, in the present embodiment, draw-in groove 2 and feet 11 are respectively by 3.
One of them draw-in groove 2 is provided with and makes elevator out of service after being triggered and the switch 5 entering inspecting state, elevator pit cat ladder is when deployed condition, and the feet 11 that switch 5 is corresponding with movable side bar 1 offsets and is triggered.In the present embodiment, switch is arranged on the draw-in groove 2 of vertically bottom.
The elevator pit cat ladder of the present embodiment locks the locking mechanism being connected and fixed side bar 8 and movable side bar 1 under being also included in and closing up state.Described locking mechanism comprises and is rotatably connected on the jam plate 6 on movable side bar 1, the tapered end 7 be fixed on fixing side bar 8 by bearing pin, described jam plate 6 has the locked groove coordinated with tapered end 7.As illustrated in Figures 5 and 6, after movable side bar 1 and fixing side bar 8 merging are drawn close, rotate jam plate 6, make its locked groove coordinate fastening with tapered end 7, movable side bar 1 Automatic-expanding when non-artificial operation can be avoided.
When maintainer needs to enter pit overhaul, open jam plate 6, expansion activity side bar 1, every root cat ladder cross bar 3 all rotates around the bearing pin 4 being connected and fixed side bar 8, until movable side bar 1 is away from fixing side bar 8 and by feet 11 feet draw-in groove 2, now the feet 11 of movable side bar 1 gets to switch 5, and elevator enters inspecting state, and maintainer can enter pit overhaul along cat ladder.After maintenance terminates, maintainer climbs out of pit, movable side bar 1 is mentioned and makes it draw close to fixing side bar merging, switch 5 resets, every root cat ladder cross bar 3 all rotates around the bearing pin 4 being connected and fixed side bar 8, until movable side bar 1 and fixing side bar 8 and tight together with, then rotated by jam plate 6 and fasten tapered end 7, maintenance terminates.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
