Abstract
The invention belongs to an escalator safety strap system. The escalator safety strap system comprises staircases, an escalator handrail frame and escalator handrail straps; the outer side of each escalator handrail strap is equipped with a safety strap device with a winding case, and a safety strap transmission device; a plurality of winding cases are fixedly mounted on a chain of each safety strap transmission device, the distance between each two winding cases is equal to that between each two staircases, and one winding case is parallel between each two staircases; and the motion trajectory and the speed of each safety strap transmission device are synchronous with the staircases and the elevator handrail strap. A safety strap is arranged between the escalator handrail straps in the escalator safety strap system, a person can use one hand to contact the handrail strap of the escalator, and the other hand to grasp the safety strap, even if the escalator is suddenly failed during running or a person slips, the person cannot fall over even roll down from the escalator due to the protection of the safety strap; and the safety strap can prevent people from walking on the escalator so as to eliminate the potential safety hazard caused by the escalator.
Description
Technical field
The invention belongs to a kind of escalator belt system.
Background technology
With the world economic development, people's living standards improve and the accelerating pace of life, the escalator has been widely applied to a variety of places to go, such as supermarkets, cinemas, squares and subway stations, and the escalator itself is a machinery and equipment, the hidden danger is unpredictable side and completely avoided, such as the elevator suddenly stopped moving forward or backwards with such failure, while standing on a ladder lift people in the elevator malfunction at the moment will result in lost focus forward or backward seize down, resulting in loss of life, safety or property, will cause serious personal injury or death, and some few people standing escalator stairs in order to catch the middle or at some time walking around the stairs when the elevator , did not help lift the handrail, in such circumstances the event of the above various elevator malfunction or his own missteps occur when more serious consequences, such as being directly above the stairs from the elevator fell together with others also pushed down causing their own and other people's life is in danger and property damage.
Thereby and can cause everything serious consequence all to be because when elevator breaks down in exercising and at this moment people do not enhance your vigilance and carry out psychological preparation in advance or some people does not have handle to be placed on people are lost do not have thing to draw when center of gravity is fallen down and hold up or fail to hold the elevator handrail to cause the accident of above elevator, directly falling down at last.We can say that escalator is one one and is threatening people's life and property safety " time bomb " at any time.
Summary of the invention
The objective of the invention is in order to remedy the deficiency that above-mentioned prior art exists, when providing unexpected in the process of moving et out of order of a kind of escalator or people to lose center of gravity because of carelessness, the escalator belt system that can as far as possible play a protective role.
For realizing the foregoing invention purpose; The solution that the present invention taked is: this escalator belt system; Comprise ladder, elevator arm-rest frame and elevator handrail; The seat belt apparatus that has take-up case is installed in the said elevator handrail outside, and in the elevator arm-rest frame outside safety strap driving device is installed; Take-up case of fixed installation on the chain that has on the said safety strap driving device, the distance between each take-up case equates with distance between per two ladders, and is parallel between per two ladders; The operation of said safety strap driving device and ladder and elevator handrail are synchronous.
Said safety strap driving device is made up of sprocket wheel, chain, chain guide wheel, sprocket shaft and transmission structures frame; Said transmission structures frame is installed in the elevator armrest support outside; And captive joint with the elevator structure frame; On the transmission structures frame of position, escalator upper strata, assemble drive sprocket axle; Drive sprocket and quilt drive sprocket wheel and are installed on the drive sprocket axle successively; Master tape movable sprocket axle is connected with the elevator motor axle; The master tape movable sprocket is assemblied on the master tape movable sprocket axle, and is connected through second chain and quilt drive sprocket wheel; On the transmission structures frame of escalator lower floor position through the assembling of passive sprocket shaft by movable sprocket, drive sprocket with connected through first chain by movable sprocket, the chain guide wheel also is housed on the transmission structures frame; Fixedly mount a block length bar shaped chain section connecting panel on every pitch chain bar of said first chain, and captive joint with take-up case.
Said seat belt apparatus is made up of take-up case, take-up case guide wheel, take-up case guided wheel slot, buckle of safety belt guided wheel slot pillar stiffener, safety strap, buckle of safety belt, buckle of safety belt guide wheel and buckle of safety belt guided wheel slot; Take-up case guided wheel slot is in the form of a ring installed through the transmission structures frame in the elevator arm-rest frame outside on one side; On the elevator arm-rest frame of another side through buckle of safety belt guided wheel slot pillar stiffener install one with elevator lifting apart from equating the buckle of safety belt guided wheel slot of the equal opening in two; Said take-up case is rectangular box-like, the built-in safety strap that buckle of safety belt is housed, and the outer side of take-up case is provided with the take-up case guide wheel and cooperates with the take-up case guided wheel slot, is fixed on the chain section connecting panel; Said buckle of safety belt front end is provided with the safety strap guide wheel, and cooperates with the buckle of safety belt guided wheel slot; Said take-up case guided wheel slot and buckle of safety belt guided wheel slot are T slot.
Said take-up case inner bottom part is equipped with connected tension spring, and the axis of rolling that staggers up and down and arrange is housed in the take-up case, and safety strap twines on it, and following row's axis of rolling two ends are held by the other end of tension spring.
Said buckle of safety belt is made up of connecting panel, safety strap guide wheel, resilience lock box and spring, and an end of said connecting panel is connected with safety strap, and the other end is through a pair of safety strap guide wheel of axle mounting, and the resilience lock box is installed in the middle of the connecting panel, and spring respectively is equipped with on the both sides, the inside.
Escalator belt system of the present invention is safety strap of design between the elevator handrail, makes on people's lift stand ladder just as a horizontal personal safety of in face of us, protecting us of city wall is arranged.Hand saver of people the handrail of elevator; Another is held the elevator safety band in hand; Even elevator unexpected et out of order or people when exercising lose center of gravity because of carelessness, at this moment people have had the protection of horizontal safety strap in the presence of just can not fall down or even roll from elevator.Such as: elevator when taking place that backward is sailed fault backward; People are because thereby inertia also continues to lose forward center of gravity; And this moment, people just can catch horizontal safety strap in the presence of to make health can not fall down because losing center of gravity or roll and descend to ladder; Even if reacting, people do not fall down downwards; Also can be stopped across in the presence of safety strap; People can not rolled and descend; Guaranteed people's safety; Thereby make people's life and property obtain the actv. guarantee, eliminated the potential safety hazard that elevator brought greatly! Prevented that also people from walking about on elevator.
