Description
Technical field
The utility model relates to the technical field of staircase protection, particularly staircase anti-biting bar.
Background technology
Elevator, staircase market competition are fierce day by day at present, and product is brought in constant renewal in.Each big elevator company simplifies approximately at the prerequisite next part of ensuring the quality of products, and the sealing band that elevator is used is constantly replaced improvement; Staircase anti-biting bar on its function, play nothing but anti-pinch, crashproof, hide ash, decoration function; Original anti-pinch device generally adopts aluminum alloy or rigid plastic to extrude part to add hairbrush and assemble, have the tooling cost height, and the Brush type structure has the shortcoming of the difficult cleaning of dust stratification, and its single-piece profile is not attractive in appearance yet.
Sketch both sides both domestic and external anti-pinch safety rate:
1, Britain delivered a large amount of articles to the safety problem of riding escalator over past ten years; the Britain HSH of labour protection mechanism health and safety actuating unit; participated in improving the safety apparatus work of escalator; proposed to install additional the requirement of hairbrush anti-pinch device; formulated design criteria PM34 simultaneously, PM34 and original same being suitable for of BS5656 " escalator and moving sidewalk manufacturing and installation safety standard ".
Though 2, not mentioned anti-pinch device in the A17.1 standard of the U.S. has the safety requirements of this respect in the state rules that have.Therefore, Americanized escalator is equipped with anti-pinch infill panel or brush unit on the apron plate of step both sides, to guarantee passenger's safety.
3, the EN115-1995 of European Union " escalator safety standard " abides by the basic security standard of EC machine design criterion, explicitly calls for escalator should add anti-pinch device.In the 6.1.5.6 bar of Singapore standard C P15:1990, stipulated the requirement that escalator must be installed anti-pinch device, show after the enforcement that its safety is more far better than originally only establishing yellow line on the step border.
4, in the 3.6.10.1 bar in revised Australian Standard AS1735.5, the safety guard-safeguard requirement of similar anti-pinch device is arranged, regulation step both sides need add yellow border simultaneously.1.1.5.5 bar regulation in the regional standard of Hong Kong: " between step left and right sides both end sides and apron plate, add anti-pinch device and can reduce accident risk ... ", and the leading dimensions and the position on the apron plate of having stipulated anti-pinch device.
5, the 5.1.5.6.3 bar of China in GB16899-1997 " escalator and moving sidewalk manufacturing and installation safety standard " clearly stipulated " adding suitable anti-pinch device between the step left and right sides and apron plate ", to guarantee passenger's safety.But this clause is constructive, is not Compulsory Feature.We then think, if stop the injury accident that step two side clearances cause, must add anti-pinch device.
The staircase anti-biting bar of staircase anti-biting bar device is made up of two parts, i.e. pedestal and staircase anti-biting bar.Pedestal must be good cell cube structure, does not allow to produce dangerous possibility, and can unload easily and do not hurt sb.'s feelings.Booty should not glued in its surface, does not have fire hazards, does not have sharp-pointed edge, and should firmly can not rupture.Anti-biting bar then should be soft, do not hinder clothing, and certain rigidity is arranged again, and anti-biting bar should be able to restore after passenger's shoes bump.The best position of anti-biting bar anti-pinch device is from staircase ladder road import and export fishback precontract 5mm beginning, be installed on the apron plate on both sides, cover the gap between running and step and the apron plate, its setting height(from bottom) should be above staircase import and export step about 50mm place.Hairbrush anti-pinch device by the common development of Britain Kleeneze Co., Ltd and Metro company, after being installed on 300 escalators of London Underground, in 14 years from 1981 to nineteen ninety-five, stair step two side clearances folder people accident is zero, and before this, 40 folder people accidents are arranged approximately every year.In the U.S. report that obtains same result of use is arranged also, the effect that as seen anti-pinch device is installed is tangible.
The patent No. is that the Chinese utility model patent " moving staircase apron plate anti-clip device " (notification number is CN2841603Y) of ZL200520014066.2 is exactly this type of design for another example; It by anti-biting bar, T connector bolt and the belt washer nut supporting with it, and end cap constitute; Anti-biting bar interfixes through supporting T connector bolt and belt washer nut and apron plate; Anti-biting bar is that hard and soft engineering plastics extrusion molding becomes an integral body by PVC; The end cap profile is the tilting arcuation; One end of end cap is provided with 3～4 wedge heads and inserts in the hole of the anti-biting bar that is installed in the staircase termination with hand, plays fixation.This structure and apron plate have adopted the connection mode of bolt and nut, and this connection mode easily causes the not straight of whole anti-biting bar and apron plate, and the part clamp bar is easily middle to arch upward, and forms the uneven phenomenon of whole piece; And this connection mode causes difficulty to current maintenance.
