The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1, from the figure as can be seen, light rail high-altitude escape device of the present invention, it comprises decelerating casing 1, rope 2 and decelerating casing lid, be provided with the groove 5 of placing rope on decelerating casing 1 surface, 5 liang of openends of groove are in use towards the below, and rope 2 is placed in the decelerating casing groove 5.Be provided with pressure slider 3 between at least one section of rope 2 and decelerating casing 1, the faying face between pressure slider 3 and the decelerating casing 1 is inclined-plane 6, and pressure slider 3 down can be along the inclined-plane 6 slides so that the rope in the groove 2 is produced extruding stressed.Pressure slider is equivalent to cut away one and the movable part that forms in the reeded decelerating casing in processing, and the wall of this movable part other sides formation grooves except the inclined-plane.Decelerating casing lid is installed on the decelerating casing from placing rope place face (front), gets loose to prevent rope and pressure slider, and stretch out from the decelerating casing lid after by the slot opening end at rope 2 two ends.In order to reflect internal structure, Fig. 1 does not give expression to the decelerating casing lid.
Described pressure slider 3 surfaces are lower than decelerating casing 1 surface, all leave the gap between decelerating casing lid and the rope and between decelerating casing lid and the pressure slider, be that the decelerating casing lid does not all contact with pressure slider with rope, with prevent between decelerating casing lid and the rope and decelerating casing lid and pressure slider between interfere, clamping stagnation, make not stretchy of pressure slider and/or rope, its result might make when escape rope can not fall or falling speed too fast.
See Fig. 1, described groove 5 is the center symmetry, and groove is made of four sections parallel straight grooves and three sections semi-circular recesses, and semi-circular recesses is used for connecting smoothly adjacent two sections straight grooves.Described pressure slider 3 is two of symmetry, lays respectively between the two sections straight grooves in the left side and between the two sections straight grooves in the right.
This light rail high-altitude escape device also comprises openable box body 4, and described decelerating casing 1, decelerating casing lid, rope 2 and pressure slider 3 constitute reducing gear, and reducing gear is fixedly mounted in the box body 4, thereby has avoided exposing outside, and commodity is better.
This product can be installed a plurality of in every joint compartment, usually be installed in light rail emergency exits top or other spacious relatively place, because when escape, situation was often relatively more chaotic, crowd's evacuation or survivor help each other when being more convenient for escaping like this, are unlikely to hinder because of the place is narrow the escape process.
Operation principle of the present invention: box body 4 is closed when flat, and is exposed outside to avoid internal structure, can indicate using method and schematic diagram at box surface.During escape, at first open box body 4, rope 2 two ends are in lax, the hang of nature, and the survivor catches an end rope 2 to fall.In the dropping process, the human body body weight by rope change into pressure to pressure slider 3 (be downward on the figure, if pressure slider be arranged on the figure in the middle of between two sections straight grooves, so pressure upwards, all the other principles are the same).Because pressure slider 3 and decelerating casing 1 contact-making surface are inclined-plane 6, therefore pressure slider 3 will be to the diagram third side to downslide, it is many more to glide, extruding tight more (rope itself just can push) to the pressure slider 3 inboard ropes that contact 2, though the rope pressure of opposite side reduces, total frictional force can be increasing; Because human body weight is certain, the acceleration that old friend's body falls is more and more littler, and when human body gravity and frictional force balance, pressure slider no longer glides, and this brief acceleration is zero, and it is stable that the human body falling speed keeps, thereby reach the automatic speed regulation purpose.Although the pressure that the people of different weight is added on the pressure slider is different, principle is the same, and difference is that the last speed that at the uniform velocity falls of the people of heavyweight vehicle will be hurry up, but can both realize at the uniform velocity falling.Certainly under equal conditions can change the size of frictional force by the quantity of increase and decrease pressure slider, thus the size of control falling speed.
When first survivor arrived ground, the rope other end then rose to the emergency exits position, and second survivor just can catch rope to continue to have escaped, so repeatedly.Therefore the rope other end can not enter in the decelerating casing lid after the length of rope wanted the guarantor to fall to putting in place at least, more can not pull from this escape apparatus, and it is necessary suitably staying some surpluses more.Rope is long more, and the escape altitude that can realize is high more.When not using, rope and pressure slider are with self-return.
The actual rope of selecting for use of escape apparatus of the present invention is a high-wearing feature rock-climbing rope, and the top layer chemical composition is a polyamide.Adopting climbs rocks restricts, and mainly considers the high-wearing feature of rock-climbing rope, and high tensile strength can be born bigger weight, convenient inspection when reaching friction effect, replacing rope.
