Abstract
The utility model discloses a lower part device on low -angle staircase installs on the staircase truss, including guide rail and curb plate, the guide rail is connected fixedly with the curb plate, the curvature radius of the guide rail on staircase truss upper portion is 2700mm, the curvature radius of the guide rail of staircase truss lower part is 2000mm, the guide rail and the horizontal plane at staircase truss middle part become 23.2 angle of inclination setting. This kind of lower part device on low -angle staircase adopts little inclination guide rail and curb plate, makes big lifting height automatic escalator in use safer, experiences more steadily comfortablely, has still adopted big curvature radius guide rail in addition, has reduced the pressure that step wheel, guide rail bore, makes the automatic escalator changeover portion milder simultaneously, moves more stably.

Description
technical field:
the utility model relates to a kind of device of low-angle staircase top and the bottom.
background technology:
Current escalator angle of inclination mostly is 30 and 35 degree, and guide rail radius of curvature is at below 2000mm, when the hoisting depth of staircase is higher, escalator due to the gradient too steep, people can be made to produce dizzy sensation, and thus may cause the generation of Peril Incident, inclination angle is larger in addition, the mistake of escalator from tilting section to horizontal segment gets over urgency, also can affect the traveling comfort that escalator is taken.
summary of the invention:
The technical problems to be solved in the utility model be to provide a kind of staircase hoisting depth larger time also can ensure the low-angle staircase top and the bottom device of travelling comfort and safety.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of low-angle staircase top and the bottom device, be installed on staircase and girder, comprise guide rail and side plate, described guide rail and side plate are connected and fixed, the radius of curvature of the guide rail on described staircase and girder top is 2700mm, the radius of curvature of the guide rail of described staircase and girder bottom is 2000mm, and the guide rail in the middle part of described staircase and girder becomes the leaning angle of 23.2 ° to arrange with horizontal surface.
As preferably, for making guide rail firmly be installed on staircase and girder, described side plate arranges multiple tapped bore, and described guide rail is connected by tapped bore bolted with between side plate.
As preferably, for making staircase also can ensure good intensity and toughness when large hoisting depth, the thickness of described guide rail steel plate is set to 5-8mm.
Compared with prior art, usefulness of the present utility model is: this low-angle staircase top and the bottom device, adopt little angle of inclination guide rail and side plate, make large hoisting depth escalator in use safer, experience more steadily comfortable, additionally use larger radius of curvature guide rail in addition, reduce step wheels, pressure that guide rail bears, make escalator transition phase more mild simultaneously, run more stable.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated:

Fig. 2 is topside schematic diagram of the present utility model
Fig. 3 is the partial enlargement structural representation on the utility model top
In figure: 1, staircase and girder 2, guide rail 3, side plate 4, tapped bore
detailed description of the invention:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of low-angle staircase top and the bottom of the utility model device, as shown in Figure 1 to Figure 3, be installed on staircase and girder 1, comprise guide rail 2 and side plate 3, described guide rail 2 is connected and fixed with side plate 3, the radius of curvature of the guide rail 2 on described staircase and girder 1 top is 2700mm, the radius of curvature of the guide rail 2 of described staircase and girder 1 bottom is 2000mm, guide rail 2 in the middle part of described staircase and girder 1 becomes the leaning angle of 23.2 ° to arrange with horizontal surface, because the angle of inclination of guide rail 2 diminishes, thus make staircase in use more mild and safety, the experience of passenger is more steadily comfortable, in addition, owing to increasing the radius of curvature of guide rail 2, thus step wheels is reduced when real-world operation, the pressure that guide rail bears, make staircase milder to horizontal transition section from tilting section, overall operation is more stable, preferably, can firmly be installed on staircase and girder 1 for making guide rail 2, described side plate 3 arranges multiple tapped bore 4, described guide rail 2 is connected by tapped bore 4 bolted with between side plate 3, in addition for making staircase also can ensure good intensity and toughness when large hoisting depth, the thickness of described guide rail 2 steel plate is set to 5-8mm, thus make staircase operationally, guide rail 2 can bear larger pressure, strengthen safety and the durability of staircase.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
