Connecting rods of the escape ramp are hinged with ramp surfaces; the connecting rods are mutually hinged; the ramp surfaces are mutually hinged; and a first section connection rod is hinged with a fixed seat. The connecting rod emergency escape ramp device has small occupation space, simple release, steady movement, short spreading time, convenient recycle, high efficiency and reliable locking by adopting a multi-stage locking device. Besides, ramp multiple stages can spread automatically and simultaneously to release all-traveling damping under the function of the power source after unlocking.
Description
Technical field
The utility model is a kind of link-type emergency escape ramp equipment, belongs to mechanical drive machinery field.
Background technology
Underground railway track train majority has designed emergency front and emergency escape ladder or emergency escape ramp now.But be used for escape ramp and Men Weimen machine integrative-structure that emergency escape is used at present, be positioned on the permanent seat,, influenced driver's the visual field because it is big to take the driver's cab space as its egress door recovering mechanism of utility model patent ZL200620018889.7; Its removal process is to reclaim inefficiency by the handle head motion.
Summary of the invention
The utility model proposes a kind of link-type emergency escape ramp equipment, it is little that its purpose is that the escape ramp recovering mechanism takes up room, the organic efficiency height.
Technical solution of the present utility model: it is characterized in that escape ramp is connected with an end of carrying band, the other end of carrying band connects recovered overhead mechanism, and propulsion source connects escape ramp, and recovered overhead mechanism is installed in the car body top; Described recovered overhead mechanism comprises the automatic recycling device and the buffer release device of carrying band, two fixed supports are arranged, between two fixed supports transmission shaft is arranged, the two ends of transmission shaft are arranged with the drawstring dish, and the bilateral symmetry of transmission shaft is provided with wind spring mechanism, two braking mechanisms be symmetricly set on the drawstring dish and wind spring inter-agency, connecting rod and ramp surface in the escape ramp are hinged, hinged between connecting rod and the connecting rod, hinged between ramp surface and the ramp surface, first segment connecting rod and permanent seat are hinged.
Advantage of the present utility model: it is little to take up room, low to the vehicle body space requirement, does not influence driver's the visual field; Discharge simple: after the release, under the effect of propulsion source, the ramp is multistage launches automatically simultaneously, discharges omnidistance damping, and motion is steady, and duration of run is short; It is convenient to reclaim, and the efficient height: only need promote the afterbody ramp surface during recovery, the ramp will fold into locked position simultaneously.Locking is reliable: adopt multistage locking device, locking is reliable.
Description of drawings
Accompanying drawing 2 is recovery structure graphs of link-type emergency escape ramp equipment.
1 is recovered overhead mechanism among the figure, the 2nd, and carrying band, the 3rd, propulsion source, the 4th, escape ramp.
The specific embodiment
Contrast accompanying drawing, its structure are that escape ramp 4 is connected with an end that carries with 2, and the other end of carrying band connects recovered overhead mechanism 1, and propulsion source 3 connects escape ramp, and recovered overhead mechanism is installed in the car body top; Described recovered overhead mechanism comprises the automatic recycling device and the buffer release device of carrying band, two fixed supports are arranged, between two fixed supports transmission shaft is arranged, the two ends of transmission shaft are arranged with the drawstring dish, and the bilateral symmetry of transmission shaft is provided with wind spring mechanism, two braking mechanisms be symmetricly set on the drawstring dish and wind spring inter-agency, connecting rod and ramp surface in the escape ramp are hinged, hinged between connecting rod and the connecting rod, hinged between ramp surface and the ramp surface, first segment connecting rod and permanent seat are hinged.Escape ramp 4 launches under propulsion source 3 effects, reclaims and installation of buffer release device and car body top.
The ramp is after the external force release during use, escape ramp is under the effect of spring force or gravity, multistage expansion simultaneously, during expansion because the shock damping action of recovered overhead mechanism 1, whole ramp launches steadily not have to impact, and during recovery, promotes the afterbody ramp surface, escape ramp 4 is with multistage folding simultaneously, up to locked position.Locking device is installed between permanent seat and the ramp surface or between ramp surface and the ramp surface.
Described locking device, its structure are that synchronizing bar connects left and right sides lock body, and left and right sides lock body adopts the multipole locking form of pusher dog, lock hook, and locking device is installed on the pedestal, is provided with the release dial in the locking device.The locking device release can be manual unlocking or operate with the emergency front interlock.
Described recovered overhead mechanism 1, the buffering damping when being provided at the ramp and discharging, discharging damping can reconcile, and the recovery power that reclaims band is provided when reclaiming.
One end of described wind spring mechanism is connected with braking mechanism by transmission shaft, and the other end of wind spring mechanism is fixed.
Brake in the described braking mechanism connects brake disc, and control apparatus and brake band join, and free-wheel clutch and wind spring mechanism join.
Described escape ramp 4, its structure is that a connecting rod and permanent seat are hinged, a connecting rod and b rod hinge connection, b connecting rod and c rod hinge connection, c connecting rod and d rod hinge connection, b connecting rod and a ramp surface are hinged, c connecting rod and b ramp surface are hinged, d connecting rod and c ramp surface are hinged, and be hinged between the ramp surface, hinged between a ramp surface and the permanent seat.The ramp is deployed in external force or the self gravitation effect promotes the action of a ramp surface down, and whole ramp is multistage launches automatically simultaneously; Only need promote the afterbody ramp surface during recovery, the ramp will fold into locked position simultaneously.Ramp surface is a two-stage or more than the two-stage.
The propulsion source 3 that provides escape ramp 4 to launch is can be gravity, spring force, hydraulic coupling, electric power, aerodynamic force, closed-center system, rope pull etc., and the expansion that is mainly the ramp provides power.
Carrying when described carrying mainly provides the ramp expansion with 2.Drawstring dish and wind spring mechanism adopt prior art.
