Description
Technical field
The present invention relates to a kind of climbing ladder apparatus, especially a kind of automatic climbing ladder apparatus for passing in and out elevator pit.
Background technology
The pit of elevator hoistways is provided with the parts such as energy disperser, safety tongs, swelling device, for the ease of to the installation of these parts and Inspection and maintenance in the future, do not having other passage easy access personal security to enter in the elevator of elevator pit, must arrange and easy access personnel can pass in and out the climbing ladder apparatus of pit.Pit ladder device is the requisite component part of whole elevator device.
In elevator industry now, it is the large attraction of one that elevator hoistways takes up room, it is less that the elevator of identical car area takies building area, and its cost performance is just relative higher, and common pit ladder device is fixed in hoistway wall by a cat ladder by expansion bolt, it takes up room larger, and common pit ladder device, distant from doorway, the Room, maintainer is more difficult gets at climbing ladder apparatus, be not easy to maintainer and enter pit, and danger of easily falling.
Summary of the invention
Main purpose of the present invention is to provide a kind of automatic climbing ladder apparatus for passing in and out elevator pit, it automatically can be opened, close, be hidden in when not using below lading door dill, more save space than traditional climbing ladder apparatus, the present invention is arranged on Ting Men entrance, base station and is more suitable for maintainer to enter pit.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of automatic climbing ladder apparatus for passing in and out elevator pit, it has opening and closing state relative to sedan-chair wall, comprises cat ladder body, for being rotationally connected the bindiny mechanism of cat ladder and well enclosure, the latching device for being locked by the cat ladder of closed condition; Also comprise and the pull bar of cat ladder sliding block joint and spring A, B of being in extended state, wherein, the pull bar other end is rotatably connected on well enclosure, and spring A two ends are separately fixed on cat ladder and well enclosure; Spring B two ends are separately fixed on pull bar and well enclosure.
Preferably, the pulling force of spring B is greater than the pulling force of spring A.
Preferably, load slide block in the guide rail of cat ladder, slide block and pull bar one end are rotationally connected.
Preferably, slide block is rotationally connected by bolt and pull bar one end.
Latching device is equipped with preferably, slide block, for being locked by the cat ladder of closed condition.
Preferably, also comprise mount pad be fixed on lading door dill under well enclosure on.
Preferably, mount pad is fixed by expansion bolt.
Preferably, cat ladder is connected on mount pad by hinge means.
Preferably, detector switch is equipped with at cat ladder two ends, is connected with the control mechanism of elevator.
The invention has the beneficial effects as follows: climbing ladder apparatus is arranged on below the lading door dill of base station in conjunction with the applying working condition of pit ladder and the integral layout of elevator by the present invention, and cat ladder, when off working state, can be packed up, and be close to well enclosure, save space; And when cat ladder is in open mode, can be firm be fixed in hoistway.In addition, whether the present invention is opened completely by two detector switch determination cat ladders controls elevator with closing, and ensure that elevator safety operation, stopping, simple to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention climbing ladder apparatus open mode structural representation.
Description of symbols in Fig. 1 is as follows: 1-cat ladder, 2-slide block, 3-hinge, 4-mount pad, 5-lading door dill, 6-pull bar, 7-spring A, 8-spring B, 9-hoistway, and 10-opens detector switch, and 11-closes detector switch.
Fig. 2 is embodiment of the present invention climbing ladder apparatus closed condition structural representation.
Detailed description of the invention
The realization of the object of the invention, functional characteristics and beneficial effect, be described further below in conjunction with specific embodiment and accompanying drawing.
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
The embodiment of the present invention is for passing in and out the automatic climbing ladder apparatus of elevator pit, it has opening and closing state relative to sedan-chair wall, comprises cat ladder body, for being rotationally connected the bindiny mechanism of cat ladder and well enclosure, the latching device for being locked by the cat ladder of closed condition; Also comprise and the pull bar of cat ladder sliding block joint and spring A, B of being in extended state, wherein, the pull bar other end is rotatably connected on well enclosure, and spring A two ends are separately fixed on cat ladder and well enclosure; Spring B two ends are separately fixed on pull bar and well enclosure.Detector switch is equipped with at cat ladder two ends, is connected with the control mechanism of elevator.Whether opened completely and closedown by two detector switch determination cat ladders.Ensure elevator safety operation, stopping.
Concrete structure is as follows:
Fig. 1 is embodiment of the present invention climbing ladder apparatus open mode structural representation.Fig. 2 is embodiment of the present invention climbing ladder apparatus closed condition structural representation.As depicted in figs. 1 and 2,
Mount pad 4 is fixed on the well enclosure under lading door dill 5 by expansion bolt, then cat ladder 1 is connected on mount pad 4 by hinge means 2.Slide block 2 is loaded in the guide rail of cat ladder 1, then with bolt, it is connected with pull bar 6, guarantee that pull bar 6 can pass through screws.Slide block 2 is moved on to cat ladder 1 the most inboard after, then by solid for the opposite side of pull bar 6 on well enclosure, pull bar 6 serves spacing effect.After slide block 2 moves on to the outermost of cat ladder 1, (as shown in Figure 1) cat ladder 1 just belongs to mode of operation, spring A7 two is separately fixed on pull bar 6, well enclosure and makes it be in extended state, spring B 8 two is separately fixed on cat ladder 1, well enclosure and makes it be in the state of being stretched equally, but the pulling force of spring B 8 is greater than the pulling force of spring A7.When elevator normally runs, cat ladder 1 is in shown in off working state (as shown in Figure 2).When maintainer will enter elevator hoistways, only the latching device of slide block 2 need be unclamped, cat ladder 1 can be opened automatically, until slide block 2 touches and opens detector switch 10 and make its action.Elevator can not normally run, and maintainer enters elevator hoistways pit, can not have an accident because of elevator misoperation.When maintainer from pit out time, cat ladder 1 must be resetted, until slide block 2 touch close detector switch 11 make its action.Elevator could normal work, avoids forgetting and cat ladder being resetted because maintainer exits pit and have an accident.
