Specific implementation mode
Fig. 1 a are shown ... in a side view the storage configuration of cat ladder according to prior art and Fig. 1 b are shown ... in a side view it and take
Use state.Cat ladder main body 1 is usually made of crossbeam 2 and longeron 3 in a manner known in the art, and middle cross beam 2 makes cat ladder
With step is extended substantially in horizontal direction and played the role of under state, longeron 3 is generally substantially perpendicular to the extension of crossbeam 2
And it is more than crossbeam 2 at both ends.As shown in Figure 1 b, make it opposite due to this construction of cat ladder main body 1 when taking cat ladder
It is restricted in the inclination angle alpha of elevator shaft wall 4, because the section of 3 topmost of longeron can resist elevator shaft wall 4.In order to
Safety take cat ladder, it is often desirable that cat ladder main body 1 can wish that inclination angle alpha is as big as possible as possible close to hall door 5, then this
Need to increase cat ladder main body 1 in storage relative to well enclosure 4 can mobile distance, as indicated by the dashed line in fig 1A, and this
Cause the waste of parking space of the cat ladder in hoistway.
Fig. 2 a are shown ... in a side view storage configuration and Fig. 2 b according to the cat ladder of the utility model first embodiment with side
View shows that it takes state.Climbing ladder apparatus 6 according to the present utility model includes cat ladder main body 1 and rotating device 7.Cat ladder main body
1 can be common steel-pipe welding structure herein, it is preferred to use the grid beam structure of aluminium alloy, especially crossbeam 2 can use lightweight
Aluminium alloy manufactures.Rotating device 7 has suspension holdfast 8 and places holder 9.The setting of suspension holdfast 8 extends in 1 lengthwise of cat ladder main body
End.Holder 9 is placed to be fixedly mounted on elevator shaft wall 4.As shown in Figure 2 a, cat ladder main body 1 is pacified by suspension holdfast 8
It sets on placing holder 9.As shown in Figure 2 b, cat ladder main body 1 can be rotated to by means of rotating device 7 around a rotation axis L de-
In open position.The rotation can be that suspension holdfast is carried out around the rotation axis relative to holder is placed.In this case, it hangs
Holder can be fixedly connected with longeron.The rotation can also be that longeron is carried out relative to suspension holdfast.In this case, it hangs
Holder can be rotatably connected with longeron.By Fig. 2 b as it can be seen that rotation axis L is parallel to well enclosure 4 herein extends.It shows in figure 2b
Rotary course in, cat ladder main body 1 can substantially rotate 180 degree relative to elevator shaft wall 4.
Fig. 3 shows the stereogram of part of the climbing ladder apparatus 6 according to first embodiment in 7 region of rotating device.In Fig. 3
Shown in place holder 9 and have from the stop configurations 10 of its main body protrusion.The length of stop configurations 10 can be with placement holder
It is identical, it can also be different.The shape of stop configurations 10 can be selected arbitrarily, as long as its function can be realized.Stop configurations 10
Cat ladder main body 1 can be prevented undesirably to be slid in storage, and its rotation axis L when rotated of cat ladder main body 1 can be made
Recline well enclosure 4 as possible, the more stable safety so that staff operates.
Fig. 4 shows the schematic diagram of the cat ladder according to the utility model second embodiment.According to the climbing ladder apparatus 6 of the present embodiment
Additionally there is haulage gear 11, cat ladder main body 1 can be driven to rotate by haulage gear 11.Haulage gear 11 in Fig. 4 is real
It applies as steel chain.Steel chain can have smaller radial dimension, and one end can be easily laid out on 5 side of hall door, and another
End and cat ladder main body 1 connect.The haulage gear 11 can also be embodied as the device that connecting rod, rope etc. arbitrarily play draw.Traction
Mechanism 11 can also be the electronically controlled draft gear (not shown) for being integrated in and placing in holder 9, and thus, it is possible to automatically will
Cat ladder main body 1 is moved to hall door 5 and is nearby easy in the region picked and placeed.
Fig. 5 shows the schematic diagram of the cat ladder according to the utility model 3rd embodiment.With the difference of first embodiment
It is, cat ladder can be stored on the well enclosure of hall door side.According to the rotation axis L of the rotating device 7 of the present embodiment perpendicular to
Well enclosure 4 extends.Cat ladder main body 1 can be rotated close to well enclosure 4 around rotation axis L herein, shown in dotted line, thus be moved to
For taking in the region of hall door 5.It is of course also possible to which traction as shown in Figure 4 is arranged for the climbing ladder apparatus 6 in the present embodiment
Mechanism 11.
Fig. 6 shows schematic section of the rotating device 7 in the plane for being parallel to elevator shaft wall in 3rd embodiment.By
For Fig. 6 as it can be seen that the upside for placing holder 9 is the prominent curved surface of arch, suspension holdfast 8 has the profile with curved surface complementation on the downside of it, from
And cat ladder main body 1 can reliably be stored by suspension holdfast 8 coordinates with the shape for placing holder 9.Meanwhile this shape is matched
Conjunction is also beneficial to rotation of the cat ladder main body 1 when taking, because suspension holdfast is to a certain extent limitedly around shape cooperation
Pivotal area rotates, and places holder and do not slided when rotated along suspension holdfast is opposite.It is of course also possible to be cat ladder main body 1
A crossbeam 2 be shape-ordinatedly shelved on place holder 9 upside on, wherein it is preferred that 2 shape of crossbeam of cat ladder body top is matched
It is shelved on closing and places 9 on holder.The curved surface of other forms, such as concave surface can also be set.
Illustrate to being given for example only property of above example the utility model, but the utility model is not limited to the implementation
Example.On the basis of the embodiment, those skilled in the art can carry out the feature illustrated in this specification arbitrary
Modification is replaced or is combined without departing from the scope of protection of the utility model.
