Description
Technical field
The present invention relates to the elimination mechanism in gap between the scalable anti-rail transit cars of stepping on hollow plate of a kind of bilayer or multilayer and the platform, belong to the invention of rail traffic station affiliated facility.
Background technology
In the track traffic, the edge of the platform must meet the requirement of vehicle near gauge to the distance of track centerline, station platform at segment of curve also must be widened this gauge, add the construction error in the civil engineering, so people's total energy finds after vehicle comes to a complete stop a no small gap is arranged between compartment and platform in the actual operation; If this station platform just in time is in the segment of curve of circuit and its radius of curvature when smaller again, because the length in every joint compartment all reaches about 20 meters usually in the track traffic, thus people, particularly be positioned at car length two ends (when car door face be the camber line outside time) or the people of the centre of car length (what face when car door is that camber line is when inboard) can find that especially a very large gap is arranged unexpectedly between compartment and platform after vehicle comes to a complete stop.Often cause the injury accident to the passenger in the rail transportation operation practice because of the excessive clearance between compartment and the platform, the accident that has remains serious, to such an extent as to passenger and rail transportation operation department face a charge in court.Just because of this, the passenger all can remind with broadcasting in rail transportation operation department all over the world when vehicle arrives at a station: " Please takes care the Inter crack between the row Trucks With platform ".At the problem of this relevant operation security, it is a kind of with the anti-sky rubber strip of stepping on of dredging tooth to imitate Hong Kong subway to use at present on the part subway line of Shanghai.Yet, although used the rubber strip of multiple different size for the gap that adapts to different sizes, but, because the rubber strip outreach fixes, the train of the multiple different size that both can't simultaneous adaptation on the same line road, uses, can't stretch out too much near gauge because of invading vehicle again, therefore, in fact people still find, even if the anti-platform of stepping on the sky rubber strip has been installed, its gap is troublingly still big, and passenger's injury accident still takes place frequently.Also the someone proposes will prevent stepping on " dead bolt " scheme that hollow plate pushes by action edge before the vehicle, " dead bolt " keeps the ejection state at ordinary times, its overhang is a bit larger tham the width in gap between compartment and the platform, relies on the external force that the incoming train compartment produces this mechanism and makes " dead bolt " indentation and be close to the compartment outer wall.This scheme can't adapt to the train of the multiple different size that uses equally because its " dead bolt " overhang is a fixed value on the same line road; And, since this mechanism rely on vehicle before action edge will prevent that stepping on hollow plate pushes, so mechanism not only is subjected to the collision of action edge before the vehicle, and because of the rectangular state of conversion of sense of motion, so its wearing and tearing and fault rate certainly will be very big; In addition, adopt this mechanism to transform, be difficult for adopting existing opening in the circuit to platform floor.Also having a kind of scheme that has patented is to be provided with by frame, the lash adjusting device that is two pedals of hinge-like bonded assembly, is made up of slide mechanism of Driven by Hydraulic Cylinder etc. by rail side at platform, its structure is very numerous and diverse, and is only applicable to state's iron and is not suitable for subway.
Summary of the invention
Perplexing the compartment of rail transportation operation department and the clearance issues between the platform all over the world for thoroughly solving this always, the invention provides a kind of elimination mechanism with gap between the scalable anti-compartment of stepping on hollow plate of bilayer or multilayer and the platform.This mechanism is installed in the side of platform, and its uppermost plane is equal with platform floor, and all anti-width of stepping on after the hollow plate indentation of mechanism are very little, are enough to remain on vehicle near within the gauge scope.
By the present invention, after train arrival came to a complete stop, control part sent signal, and at this moment, the execution unit of mechanism is released the anti-hollow plate of stepping on of bilayer or multilayer forward until touching the compartment shell and stopped by movable parts; Perhaps, if it is big to locate the gap all too, the bilayer at this place or multilayer prevent that stepping on hollow plate will all be shifted onto the end so.Next, train opens the door, on-board and off-board, closes the door.After train door closed, control part sent signal again, and at this moment, execution unit is all regained all anti-hollow plates of stepping on that stretch out by movable parts again.Then, train is dispatched a car and is sailed out of platform.
From above as can be seen: 1. the present invention does not have any contact with railway car in train sails the process of platform into; 2. the present invention is just contact with it after train comes to a complete stop, and does not therefore exist any power to collide; 3. no matter the gap between compartment and the platform is much, and the present invention all can be with its whole coverings; 4. even some local gap is excessive really, the present invention also can farthest reduce this gap, thereby makes it no longer include the anxiety of hidden danger; 5. the present invention does not also have any contact with railway car in train sails out of the process of platform; 6. the present invention can adapt to the train of any specification.
The technical solution adopted in the present invention is: the side of the platform anti-hollow plate of stepping on that bilayer or the mutual intussusception of multilayer is housed and can moves mutually AT STATION wherein has one deck to prevent stepping on the side that hollow plate is fixed on platform.After train arrival came to a complete stop, control part sent the anti-signal that hollow plate is released forward of stepping on.At this moment, the execution unit of mechanism (can be motor, electromagnet, electric pushrod etc.) is promptly stepped on the anti-hollow plate of stepping on of that piece that can push away farthest in the hollow plate by movable parts (can be chute slide block, rolling wheel guide rails, bolt and nut, lever, planar linkage, spring etc.) with mutual intussusception anti-and is released until the shell that touches the compartment forward abreast or release on earth, in this process, the anti-hollow plate of stepping on of that piece prevents movably that with other stepping on hollow plate takes out of forward together by being located at the anti-stops of stepping on the hollow plate of each piece.。After treating that train door closes, control part sends signal once more.At this moment, execution unit is regained the anti-hollow plate of stepping on that piece can push away farthest backward abreast by movable parts again, and in this process, the anti-hollow plate of stepping on of that piece prevents movably that with other stepping on hollow plate takes back together backward by being located at the anti-stops of stepping on the hollow plate of each piece.
The invention has the beneficial effects as follows: simple in structure, with low cost, safeguard easily long service life.It both had been applicable to rail line newly-built or that do not build, also was applicable to the rail line of having built or having come into operation; Both be applicable to subway line, also be applicable to state iron wire road.The most important thing is that it can thoroughly stop the injury accident to the passenger that causes because of the gap between compartment and the platform.
