Abstract
The utility model discloses an automatic staircase handrail area overspeed device tensioner, including tension support (1), extend along upper and lower direction and fix screw rod (5) on tension support (1) and install from top to bottom with sliding tensioning assembly (6) on screw rod (5), the below of tensioning assembly (6) is equipped with elastic component (2) that provide the tensile force, it is right that screw rod (5) last threaded connection has the lower extreme of elastic component (2) carries out spacing nut (4). Compared with the prior art, the utility model discloses structural design is ingenious, and convenience, safe and reliable are adjusted moreover to automatic tensioning handrail area to a certain extent.
Description
Technical field
The utility model relates to escalator hand rail tension device.
Background technology
At present, tilting handrail escalator is widely applied to each occasion, and the usage safety performance of escalator also constantly receives more concern.Handrail is the movable parts on escalator, and passenger can hold handrail when boarding, avoids falling.In order to ensure the synchronism of handrail and step speed, preventing the passenger's wrestling accident caused because handrail skids, needing after usual handrail installs to carry out tensioning to it.Escalator is in the market carry out tensioning handrail by knuckle place quadrant on movable escalator mostly, also needs to readjust quadrant position, prevent handrail sideslip after each tensioning is complete, comparatively complicated.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of easy to adjust, safe and reliable escalator hand rail tension device.
For achieving the above object, the utility model provides a kind of escalator hand rail tension device, it is characterized in that: comprise tensioning support, extend the screw rod be fixed on described tensioning support along the vertical direction and slide up and down to be arranged on the tension assembly on described screw rod, the below of described tension assembly is provided with the elastic component providing tensile force, described screw rod is threaded carry out spacing nut to the lower end of described elastic component.
Preferably, described tension assembly is provided with pinch roller and carrying roller, and the handrail of escalator passes from described pinch roller and described carrying roller.
Wherein, described elastic component is spring, and it is socketed on described screw rod, and the lower end of described elastic component is provided with spring perch, and described nut support is in the below of described spring perch.
In a particular embodiment, the quantity of described screw rod is two, and two described screw rods are separately positioned on the both sides of described tension assembly.
After the escalator hand rail tension device that the utility model provides has been assembled, supported on angle steel by tensioning support installing horizontal segment on truss, the position of described nut corresponding upper horizontal segment detachable in retaining wall place.When needs tensioning handrail, only need dismantle upper horizontal segment place detachable in retaining wall, by tightening the nut be positioned at below elastic component, compress elastic component, the elastic-restoring force effect after elastic component compression plays the upwardly effect of tensioning handrail to tension assembly.
Due to the elastic component below tension assembly of the present utility model spacing by nut after be in compressive state always, the effect of auto-tensioning can be played to a certain extent, avoid handrail to occur the phenomenon of skidding because tensioning is not enough.Compared to prior art, the utility model smart structural design, easy to adjust, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is that the utility model is arranged on the using state schematic diagram after on moving staircase girders.
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.
Refer to Fig. 1 and 2, a kind of escalator hand rail tension device, comprise tensioning support 1, elastic component 2, spring perch 3, nut 4, screw rod 5 and tension assembly 6.Tension assembly 6 is provided with pinch roller 61 and 4 carrying rollers 62.
Tensioning support 1 is made up of with the crossbeam be connected along two heel posts the column of both sides, also has connecting panel 11 bottom two root posts.The quantity of screw rod 5 is two, connects root screw rod 5 and extends along the vertical direction respectively and be fixed on tensioning support 1, and two screw rods 5 are positioned at the both sides of tension assembly 6.The upper and lower side of every root screw rod 5 is fixed on tensioning support 1 respectively by nut.Tension assembly 6 can slide up and down to be arranged on a pair screw rod 5, and elastic component 2 is arranged on below tension assembly 6 to provide tensile force.Elastic component 2 in the present embodiment is spring.Every root screw rod 5 is all arranged with this elastic component 2, and the below of elastic component 2 is provided with carries out spacing nut 4 to the lower end of elastic component 2.In order to install elastic component 2 better, being also provided with spring perch 3 pairs of elastic components 2 between the lower end of elastic component 2 and nut 4 and supporting.
After the escalator hand rail tension device of the present embodiment has been assembled, the lower end connecting panel 11 of tensioning support 1 and the support angle steel 100 of horizontal segment on moving staircase girders are fixed, the position of fixing back nut correspond to upper horizontal segment detachable in retaining wall place.Now, handrail 7 passes between pinch roller 61 and carrying roller 62.Under the elastic-restoring force effect of elastic component 2, tension assembly 6 all the time upwardly and by handrail 7 tensioning, thus avoids handrail 7 to occur skidding.When needs tension adjusting, as long as taken apart by detachable interior retaining wall, the position of the nut 4 on every root screw rod 5 is regulated to realize, very convenient.Upwards compressible elastomeric part 2 during setting nut 4, thus increase tensile force; Elastic component 2 can be loosened during downward setting nut 4, thus reduce tensile force.
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.
