Description
Technical field
The present invention relates to a kind of moving staircase apron plate anti-clip device that is applicable to.
Background technology
Escalator has been widely used in large-scale public places such as market, subway, airport because of it has the characteristics that high efficiency transports the major pedestrian movement, and therefore, its safety is even more important.Stipulated the step of escalator and the gap between the apron plate in the national standard, and requirement should reduce between step and the apron plate possibility of the resistance that stagnates, also can add anti-pinch device and solve.The existing both at home and abroad hairbrush anti-pinch device that adopts, it is to adopt in English, the U.S. the earliest, pedestal and hairbrush that the hairbrush anti-pinch device is made by aluminum alloy are formed, be installed on the apron plate on escalator both sides, cover the gap between running and step and the apron plate, so that stair step both sides folder people accident is zero.But this installation cost height, the fabrication and installation complexity.Also there are indivedual countries to adopt economical and practical adhesive tape anti-pinch device, are about to rubber strip and are pressed into D type cross section, fix with the apron plate then.Because the friction coefficient of elastomeric material is big, is pulled sensation in case the passenger runs into to have, when rubber strip breaks away from the apron plate, can bring certain danger to the passenger.The innovation and creation of this aspect do not appear in domestic and international by retrieval patent.
Summary of the invention
The purpose of this invention is to provide a kind of economical and practical apron clamp preventer, it has following characteristics: 1, the anti-biting bar of anti-pinch device adopts the disposable extrusion moulding of engineering plastics, end cap adopts the engineering plastics once injection moulding, compare the hairbrush anti-pinch device, has the advantage that making is simple, cost is low, save social resources and the neat and artistic environmental protection again of product, engineering plastics can recycle and reuse again, and have avoided the drawback of the difficult cleaning of hairbrush dust stratification dirt of prior art.2, the software partial sum end cap of anti-biting bar all adopts escalator general-duty safety yellow, and runs through the visible part of step, has tangible safety instruction mark, is easily aroused attention by the passenger-in-elevator, reaches safe using escalator purpose.3, by adopting the T connector bolt to be placed on space, T type hole on the anti-biting bar, thereby realized fixing with the apron plate simply, had easy for installation firm again.4, assign to link to each other admittedly with the apron plate with the rigid portion of anti-biting bar, it is firm to have more installation, avoids anti-biting bar to come off.In a word, this device have design science rationally, make simple, installation and maintenance are convenient, safe and reliable, cost is low, have more good looking appearance characteristics such as economy and durability and recyclable utilization again, are the desirable substitutes of prior art.
Introduce concrete technology contents of the present invention below.
A kind of escalator apron clamp preventer, it comprise anti-biting bar (4), T connector bolt (6) and the belt washer nut (5) supporting with it, and end cap (9) constitute; Anti-biting bar interfixes with apron plate (1) through supporting T connector bolt (6) and belt washer nut (5); Wherein: anti-biting bar (4) is an integral body by hard, soft pvc engineering plastics one property time extrusion moulding, has to manufacture easy, the low advantage of cost; Anti-biting bar hardware that the hard PVC engineering plastics make part (2) is positioned at the inboard/rear portion of anti-biting bar (4), and intensity is good because the hard PVC engineering plastics have, it joins with the apron plate and guaranteed firm and anticreep; The anti-biting bar software part (3) that the soft pvc engineering plastics make is positioned at the outside/front portion of anti-biting bar (4), utilizes the flexibility of flexible plastic, has avoided personnel to damage effectively; On anti-biting bar hardware part (2), there is a space, T type hole (7) closed or open type to supply to place T connector bolt (6); Anti-biting bar (4) passes the Kong Zaiyu belt washer nut (5) that is preset on the apron plate (1) thereby screws through T connector bolt (6) realizes mutual fixing; The profile of end cap (9) is the tilting arcuation; One termination of end cap (9) is provided with 3～4 wedge heads (8), is used for inserting the hole/cavity of the anti-biting bar (4) that is installed in the staircase termination, plays fixation, is designed to the end cap of arcuation, makes overall appearance that safety be arranged.Above-mentioned apron clamp preventer can be established a through hole (10) on end cap (9), penetrated fixedly end cap effect for a screw.In addition, the hardware of anti-biting bar (4) part (2) and software part (3) can be double-colored, and wherein software part (3) is a safety yellow; End cap (9) also is a safety yellow; Software part (3) and end cap (9) adopt safety yellow, have the passenger's of expressing effect, make it have more safety.
