Abstract
A foldable slope mechanism at the terminal of subway carriage for emergency evacuation of passengers is composed of a slope way consisting of two vertical posts and at least three plates, supporting rods, several hinges for linking adjacent two plates and a supporting rod, the pull cables for each supporting rod and the tops of all supporting rods, and the pneumatic springs between plate and supporting rod.
Description
Technical field
The present invention relates to ramp installation at end head of railway vehicle for emergency evacuation.
Background technology
Subway train has adopted emergency exits in driver's cab the place ahead in the lifesaving escaping system, in case emergency situations such as fire occur, can't open as car door, the driver can start emergency facility immediately, open emergency exits, the passenger can in time be evacuated by the escape road of train.The escape road of early stage subway train is outwards overturn by emergency exits and promptly forms, and this escape road is because of being subjected to the restriction of its length, and is very steep, can only be stair, and current inconvenience influences evacuating personnel speed, and opens, draws in all inconvenient.China Patent No. is that 2006200188889.7 utility model discloses a kind of underground locomotive escape door device, the door body of emergency exits be the middle part hinged, open the back and become tabular, draw single folding formula door body that the back forms inside and outside layer in, the bottom of door volume surrounding is hinged on the car body, has long ramp after opening, so it is the ramp is comparatively mild, current convenient.Because what adopt is the drag-line jack, structure is complicated.
Summary of the invention
The objective of the invention is to propose a kind of multi-bended ramp installation at end head of railway vehicle for emergency evacuation simple in structure.
For achieving the above object, the present invention takes following technical scheme:
The present invention has two columns and is in the ramp that two column the place aheads are made up of at least three guidance tapes, hinge by the left and right sides between the adjacent guidance tape connects, and on the hinge of every hinge a hinged strut bar, be provided with gas spring between the middle side edge of the guidance tape homonymy at the bottom of each strut bar and its rear, be provided with drag-line between the side front portion of the guidance tape homonymy in the top of each strut bar and its place ahead, jointed shaft by the left and right sides between two columns and its place ahead guidance tape is connected, and is provided with drag-line between the side front portion of the top of every column and its place ahead guidance tape homonymy.
Described guidance tape is four.
Between described column top and its place ahead homonymy support bar top, be between the adjacent supports masthead portion of homonymy and all be connected with hand rope.
Drag-line between the guidance tape in described column and its place ahead is a chain.
The guidance tape in described two column the place aheads is a cambered plate.
The present invention has following good effect:
The present invention is multi-bended ramp, is connected by gas spring between its guidance tape, is connected by jointed shaft between column and the place ahead guidance tape, and is simple in structure; Owing to be multi-bended ramp, the ramp can be longer, and after opening, the ramp is mild, makes things convenient for personnel's evacuation, and it is lower to draw the needed collection space height in back in, not only can adapt to the height of locomotive, and the space on this device top can utilize also.
Description of drawings
For the easier quilt of content of the present invention is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the present invention is further detailed explanation, wherein
Fig. 1 is an open mode configuration diagram of the present invention;
Fig. 2 is a rounding state configuration diagram of the present invention;
Fig. 3 is that the A of Fig. 2 is to view.
The specific embodiment
See Fig. 1, the present invention has two columns 1 and is in the ramp that two columns, 1 the place ahead is made up of at least three guidance tapes 2, the ramp of present embodiment is made up of four guidance tapes 2, and wherein the guidance tape 2 in two columns, 1 the place ahead is a cambered plate, makes the eminence in ramp have a smooth place to be connected with vehicle body ground.Hinge 3 by and arranged on left and right sides between the adjacent guidance tape 2 connects, hinge 3 comprise be connected to before and after two flap 3-2 and the hinge axis 3-1 that is connected two flap 3-2 on the guidance tape, and on the hinge 3-1 of every hinge a hinged strut bar 4.
Be provided with gas spring 5 between the middle side edge of the middle and lower part of each strut bar 4 and the guidance tape at its rear 2 homonymies, promptly be provided with gas spring between the middle part, limit, Zuo Ce strut bar and rear portion guidance tape left side, be provided with gas spring between the middle part of the strut bar on right side and rear portion guidance tape right edge, left and right gas spring must be symmetrical arranged.Gas spring 5 with take on the middle and lower part of each strut bar 4, to be provided with support 4-1 being connected of rear portion guidance tape 2, the middle part of guidance tape 2 respective side at its rear is provided with support 2-1, and gas spring 5 is connected between the support 2-1 of the support 4-1 of cooresponding strut bar 4 and guidance tape 2 by bearing pin 4-11 and bearing pin 2-11.
Be provided with the rope formula drag-line 6 that can bear pulling force between the side front portion of the top of each strut bar 4 and the guidance tape in its place ahead 2 homonymies.Drag-line 6 with take to be provided with attaching parts 6-1 being connected of guidance tape 2 in guidance tape 2 respective side front portions, the lower end of drag-line 6 is fixed on the attaching parts 6-1.
Be connected by the short jointed shaft 1-1 in the left and right sides between two columns 1 and its place ahead guidance tape 2.Be provided with chain drag-line 7 between the side front portion of the top of every column 1 and its place ahead guidance tape 2 homonymies.Because flap is installed in the front portion of guidance tape 2, chain drag-line 7 connects with the front portion of corresponding guidance tape 2 to be taked to connect drag-line plate 7-1 on the flap of this guidance tape 2, and the lower end of chain drag-line 7 is connected on the drag-line plate 7-1.
Be connected with hand rope 8 between described column 1 top and its homonymy strut bar 4 tops, the place ahead, be between adjacent supports bar 4 tops of homonymy and all be connected with hand rope 8.
See Fig. 3, be in after the gathering with the approaching guidance tape 2 of car body on promptly on eminence second guidance tape 2 down, be provided with latch fitting 10, latch fitting 10 comprises lock knob 10-1, upper lock tongue, following dead bolt 10-2 and is arranged on the interior lock core of above-mentioned guidance tape, rotation lock knob 10-1, drive upper and lower dead bolt 10-2 action, upper and lower dead bolt stretches out in the cooresponding lockhole that inserts car body, and device is locked, and anti-locking apparatus is opened voluntarily.
The present invention is installed in the emergency exits inboard of locomotive, and under the normal circumstances, the present invention is in the rounding state of Fig. 2 and is locked on the car body.
When emergency situation took place, emergency exits were opened in release simultaneously, gave the thrust in ramp of drawing in, and the ramp is under the action of gravity of elastic force and ramp of gas spring own, and guidance tape 2 is steadily opened one by one.During gathering, need manually guidance tape to be collapsed one by one.
