Abstract
The utility model relates to a rail vehicle unhook protection device, include: the symmetry be fixed in end beam below two protection box, respectively insert these two protection box and elastic fixation safe chain pole, connect chain hook and chain link on two safe chain poles respectively, the back end rotation of safe chain pole has the nut, the front end of nut is provided with the dog of cover on safety chain pole, on the safe chain pole still the cover spring that supports protection box front side inner wall and this dog respectively in both ends is equipped with. The utility model discloses coupling protection device adorns respectively in the bottom of the both ends of vehicle end beam, hangs adjacent protection device's chain hook up with the chain linkage during vehicle operation, passes through the protection device towing vehicle of vehicle during the unhook occurence of failure.
Description
Technical field
The utility model relates to guideway vehicle unhook fender guard, belongs to chassis of rail vehicle design of terminations technical field.
Background technology
After entering 21st century, countries in the world continue to strengthen railway construction, bring unprecedented business opportunity to domestic passenger train outlet.But abroad some existing lines are long neglected and in disrepair, cause hitch in vehicle operating to beat frequently, some country cannot ensure that conventional maintenance maintains in addition, usually occurs unhook accident, just in case occur in dangerous zone, consequence is hardly imaginable.So it is very necessary to need to design a kind of unhook fender guard, this device can after generation unhook accident, and the station still near towing vehicle arrival or maintenance point, ensure the safe operation of train.
The structure of domestic consideration this respect designing requirement is just at the early-stage, and mostly is loose assembling, and complex structure, the severe crush installing space of other structures of end and equipment.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, provides a kind of guideway vehicle unhook fender guard, by traditional loose package assembly modularization, is easily installed in car bottom portion, abdicates installing space to other structures and equipment.
In order to solve above technical matters; the guideway vehicle unhook fender guard that the utility model provides; it is characterized in that comprising: be symmetrically fixed on two protection boxs below end carriage, insert these two protection boxs and resiliently mounted snubber chain bar, be connected to chain hook on two snubber chain bars and chain link respectively; the rear end of described snubber chain bar is rotary with nut; the front end of nut is provided with the stops be enclosed within snubber chain bar, snubber chain bar is also set with the spring that two ends prop up protection box front inner wall and this stops respectively.
The utility model also has following improvement:
1, the afterbody perforate of described snubber chain bar, is inserted with spring cotter in hole, to prevent nut loosening.
2, described end carriage leading flank is welded with two hooks, in not running at vehicle, tangle chain link and chain hook.
3, during vehicle operating, between the hook of Adjacent vehicles and chain link to extension connect, hitch once come off, by described hook and chain link transmitting tractive power.
The utility model hitch fender guard is contained in the bottom of the two ends end carriage of vehicle respectively, the chain hook of adjacent fender guard and chain link is connected and hang up, by the fender guard towing vehicle of vehicle when unhook accident occurs during car operation.This fender guard spring plays buffer action, can comparatively be transmitted by tractive force by pulsation-free; Protection box one is that draw beam is passed to underframe, and two is can be used for protecting spring, prevents the stuck spring of the foreign material under car; And by protection box by a series of accessory module, form a module, be arranged on easily bottom end carriage, release installing space to other structures and equipment on car; Snubber chain bar afterbody is provided with screw thread, by nut pretensioned spring, effectively prevents nut loosening, and is equipped with spring cotter and prevents nut from coming off, and ensures train operation safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is guideway vehicle unhook fender guard schematic diagram.
Fig. 2 is guideway vehicle unhook fender guard exploded view.
Number in the figure is schematically as follows:
1-protection box; 2-links up with; 3-snubber chain bar; 4-spring; 5-chain link; 6-chain hook; 7-nut; 8-stops; 9-spring cotter; 10-end carriage, 11-unhook fender guard.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment guideway vehicle unhook fender guard 1 is arranged at below end carriage 10, comprise: be symmetrically fixed on two protection boxs 1 below end carriage, insert these two protection boxs 1 and resiliently mounted snubber chain bar 3, be connected to chain hook 6 on two snubber chain bars 3 and chain link 5 respectively, the rear end of snubber chain bar 3 is rotary with nut 7, the front end of nut 7 is provided with the stops 8 be enclosed within snubber chain bar 3, snubber chain bar 3 is also set with the spring 4 that two ends prop up protection box 1 front inner wall and this stops 8 respectively; The afterbody perforate of snubber chain bar 3, is inserted with spring cotter 9 in hole, to prevent nut loosening.
As shown in the figure, end carriage 10 leading flank is welded with two hooks 2, in not running at vehicle, tangle chain link 5 and chain hook 6.During vehicle operating, between the hook of Adjacent vehicles and chain link to extension connect, hitch once come off, by hook 6 and chain link 5 transmitting tractive power.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
