Embodiment
The utility model can be further well understood by specific embodiment of the utility model given below, but
They are not to restriction of the present utility model.The part for not having to describe in detail in specific embodiment is using prior art, known
What technological means and professional standard obtained.
Including cat ladder, linkwork and the supporting mechanism being fixed on the well enclosure of elevator hoistways, the cat ladder includes more
Individual treadle, one end of the linkwork are rotatably connected on the well enclosure, and the other end of the linkwork can turn
It is connected to dynamicly on the cat ladder, it is characterised in that：The supporting mechanism includes being used for the supporting section for supporting the cat ladder；It is described
Pit ladder device also includes the safety device that control elevator resumes operation after being used to be triggered, and the cat ladder has reception position
And expanded position,
As shown in Figures 1 to 6, the utility model provides a kind of pit ladder device, including cat ladder 4, linkwork 3 and solid
The supporting mechanism 2 being scheduled on the well enclosure 5 of elevator hoistways, cat ladder 4 include two vertical rods 42 and between two vertical rods 42
Multiple treadles 41 parallel to each other, one end of each linkwork 3 is by length direction parallel to flat where the well enclosure
The feathering axis 31 in face is rotatably connected on well enclosure 5, and each cat ladder 4 is provided with length direction parallel to vertical rod 42
The chute 43 of length direction, the other end of linkwork 3 are provided with rotating shaft 32, and rotating shaft 32 is slided around itself axial rotation and along chute 43
It is located in dynamicly in chute 43；Supporting mechanism 2 include be fixedly connected with well enclosure 5 canned paragraph 23, the branch for supporting cat ladder 4
Section 22 and the stop section 21 positioned at the outside of supporting section 22 are supportted, the plane where supporting section 22 is hung down with the plane where well enclosure 5
Directly, height of the height higher than the upper surface of supporting section 22 of the upper surface of section 21 is stopped.
The pit ladder device is also including access elevator safety loop for controlling what elevator resumed operation after being triggered
Safety device 1, the safety device 1 are fixed on the canned paragraph 23 of supporting mechanism 2 and in supporting sections 22, the safety device 1
For the trigger switch for the trigger unit 11 being arranged on projection on supporting section 22.
Climbing ladder apparatus in the utility model at least has reception position and expanded position, and in reception position, cat ladder 4 leans on
Nearly well enclosure 5, and a treadle 41 of cat ladder 4 is located on supporting section 22 and triggers safety device 1；In expanded position, cat ladder 4
Away from the well enclosure 5, and treadle 41 departs from supporting section 22 and separated with safety device 1, and safety device 1 is not triggered, described
Elevator is out of service.
Each two is located at one group of the composition of chute 43 of the sustained height position in two vertical rods 42, every group of chute 43 respectively
In two chutes 43 relative to cross treadle 41 midpoint vertical line it is symmetrical, length direction of three groups of chutes 43 along cat ladder 4
Interval is equally spaced.Correspondingly, linkwork 3 also amounts to six including three groups, and chute 43 is waist round hole.
The bending part that supporting mechanism 2 is formed in one, place plane canned paragraph 23 parallel to each other and stop section 21 are by propping up
