Abstract
The utility model discloses an anti-clamping device at an angle position between an escalator and a floor, belongs to the technical field of escalator safety protection and aims at overcoming defects that existing devices can't timely and reliably prevent risks from further deteriorating once people are clamped at the angle position between the escalator and the floor. The anti-clamping device comprises the escalator, the floor, a button box and an anti-clamping rod, the button box is fixedly installed on the floor, a normally open button is installed in the button box, a contactor is arranged in an electric control system of the escalator, a coil of the contactor and the normally open button are in serial connection to be connected with a power supply, a normally closed main contact of the contactor is in serial connection to be connected with a power supply line of the escalator, the anti-clamping rod is installed at the edge of the floor, the edge of the floor faces towards the escalator, one end of the anti-clamping rod, which faces towards the inside, is hinged with a base which is installed on the floor, and the other end of the anti-clamping rod is pulled by a tension spring to extend into the button box to touch a button head of the normally open button. The anti-clamping device is applicable to places where angles are formed between escalators and floors.
Description
Technical field
The utility model relates to a kind of escalator safety protection technique, particularly relates to anti-pinch people's device of a kind of escalator and floor angle.
Background technology
Raising along with Chinese economic development and social civilization degree; In order to save people's physical demands; In current many places, the escalator that the confession people steps on building use downstairs all is housed like market, the waiting hall for airplanes of waiting, library, exhibition center, subway station even public places such as overpass or tunnel.To have two property characteristics the same with a lot of things; Escalator provide convenience to us, laborsaving, efficiently in the favourable one side; Also exist the possibility that safety misadventure takes place; If we are negligent of security control; Be not actively to get rid of hidden danger in time, can take place all at any time that the occupant falls down or in the escalator operation process occupant head and hand is damaged by the obstacle on next door or occupant's footwear, toe, heel, clothing, bag such as are clamped at Peril Incident, have in addition can cause personal injury therefrom.What especially attract people's attention is: in the occasion of many device escalators, an angle is arranged all between staircase and the floor, and also all suffer too tightly between the two; Angle as the formation scissors; Particularly children and old man are as stretching out beyond the staircase because of some former excuse or hand for the occupant, and unfortunate being clamped gently then crushed; Heavy then clamped like head, then can lead to dead tragedy.Though, in the upper, middle and lower of each escalator a danger button is arranged respectively all, in case when escalator generation dangerous situation, can press the button the very first time near the passenger of button, staircase will stop automatically.But, because the appearance of dangerous situation will will have a course of reaction from recognizing action through interpersonal information transmission; To go also seek to find that danger button etc. all needs the time; Often wait until that danger button has an effect, staircase stops automatically, and accident has caused disastrous effect.Therefore, clamped head or other positions of health by the angle between escalator and the floor, wanted to avoid dangerous situation to worsen and be difficult to realize by touching the button by other people if the occupant is unfortunate.
Summary of the invention
The purpose of the utility model provides anti-pinch people's device of a kind of escalator and floor angle, overcomes present escalator and floor angle, when in a single day folder people dangerous situation taking place, does not have in time reliably to stop the further deficiency of the device of deterioration of dangerous situation.
The utility model is achieved through following technical proposals.
The utility model comprises escalator and floor; Be provided with button box; Said button box fixedly is loaded on the said floor, is equipped with in it often to drive button, in the electric control system of said escalator, is provided with contactless switch; Power supply is inserted in the coil of said contactless switch and the said button series connection back of often opening, and the normally closed main contact series connection of said contactless switch inserts in the power supply line of said escalator; Be provided with anti-clamping bar, said anti-clamping bar be loaded on said floor towards the edge of said escalator, its inwardly one be loaded on that pedestal on the floor is hinged, its other end is held by extension spring and the termination stretched into touch in the said button box on the said button head of often driving button.The mentality of designing of the utility model is: the people is in case folded by above-mentioned angle; Will inevitably touch said anti-clamping bar, said anti-clamping bar can be pressed the said button of often holding immediately, because the said button making current of often opening; Make said contactless switch action; Said normally closed main contact is thrown off, and then said escalator power power failure is stopped immediately automatically.
For fear of by folder occupant's head when stretching to such an extent that go out, head is bigger again, and when head is clamped by said floor, said anti-clamping bar but is in the recessed gesture of neck place, can't in time play the anti-pinch effect; Therefore, said anti-clamping bar is provided with a plurality of abreast, and correspondingly, said button box also is provided with, and the said button of often opening a plurality of equally, in it is parallel connection on electric wiring.
Against existing technologies, the beneficial effect of the utility model is:
When the angle of said escalator and said floor, when folder people dangerous situation takes place, can stop timely and effectively leading to of casualty accident.
Description of drawings
Fig. 1 is the structural representation of the utility model (said anti-clamping bar is provided with three abreast), Fig. 2 be the A of Fig. 1 to view, Fig. 3 is the electric wiring scheme drawing.Among the figure: 1, escalator, 2, floor, 3, button box, 4, often drive button, 5, contactless switch, 6, normally closed main contact, 7, anti-clamping bar, 8, pedestal, 9, extension spring.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
The safety precaution of the relevant escalator 1 of the utility model in operational process; So anti-clamping bar 7 should be loaded on easy angle of clamping the people; Button box 3, pedestal 8 and extension spring 9 must be installed on floor 2 firmly, and the flexible movements of anti-clamping bar 7 are reliable, can be when one touches human body demand working often open button 4; All the other other parts should be carried out related specifications and install, and should include in simultaneously in the security control and periodical maintenance turnaround plan of escalator 1.After the utility model is implemented, when escalator 1 operation, pressed from both sides like in a single day head or other positions of health that the occupant is taken place; Touched anti-clamping bar 7 before this; An end of preventing coming bar 7 is pressed to the button head of often driving button 4, often opened button 4 conductings, the coil electricity of contactless switch 5; Normally closed main contact 6 is thrown off, and makes the power failure of escalator 1 and stops automatically immediately.In case dangerous situation is got rid of, an end of anti-clamping bar 7 unclamps from often opening button head, behind the service restoration of escalator 1, because the self-locking of the power-supplying circuit of escalator 1 is thrown off, must restart, and escalator 1 could recover normal operation.
