Description

A kind of hitch hook neck locking antihunting device of rolling stock

[technical field]

The utility model relates to a kind of rescue auxiliary device, especially relates to a kind of hitch hook neck locking antihunting device of rolling stock.

[background technology]

Known, along with popularizing of railway electrification, rescue brings great difficulty to vehicle, and traditional lifting must be evaded the contact system of electrified railway, so that guarantee personal safety; And need work the car vehicle of answering a pager's call with the shortest time, repair circuit, guarantee the open-minded rapidly of railway main track, station throat track switch, make railway transportation unimpeded, the minimizing accident is reduced to bottom line to the interference and the influence of whole railway transportation with causality loss.

Owing in accident rescue, at first should in time organize locomotive to save oneself, or it be multiple to organize breakdown gang to utilize rescue re-railing equipment to rise, and causality loss and influence are minimized; The existing instrument of saving oneself mainly contains rerailer, broken equipment, track crane and the large-scale breakdown train cut of hydraulic pressure; Track crane places an end of breakdown train.Track crane is to be the lifting appliance of power with the diesel engine, and the lifting tonnage does not wait from 60～160t, and concrete effect is the locomotive, the vehicle that derail, overturn to be sling reset.Make accident take off 0 rail vehicle under the tractive of equipment such as traction machine by rerailer then, wheel is rolled along the rerailer slope by ground and is increased to rail top rerail.But accident is not to be subjected to manpower control, various situations all may occur, especially vehicle casing and vehicle casing break away from, there are not enough spaces that lower vehicle is bundled, penetrates hoisting wirerope, so force the rescue time of some vehicle long, this mainly is because vehicle does not have suitable fulcrum to insert hydraulic jack.

I am at Chinese patent (the hitch antihunting latching device of name of patent application, a kind of rolling stock of first to file; Application number, 201020156124.6; The applying date, on April 13rd, 2010) in use find because the difference of vehicle, so the hook tail both sides and the coupling for land vehicle spacing of hitch are also not of uniform size, lack practicality, above-mentioned patent only is fit to the electric locomotive of Shaoshan type series and the hook tail both sides and the less vehicle of coupling for land vehicle spacing of part hitch, hook tail both sides and the bigger but not really practicality of vehicle of coupling for land vehicle spacing with respect to hitch, and also have the gap at the hook tail top and the coupling for land vehicle of hitch, make the hitch stability of jack-up can not get guaranteeing.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model discloses a kind of hitch hook neck locking antihunting device of rolling stock, the hitch hook neck locking antihunting device of described rolling stock utilizes the cooperation of plate, side plate and high strength bolt, high-strength nut to realize the antihunting of hitch, overcome the fixing drawback of the hitch that can not adapt to the other parts vehicle of prior art, actv. has overcome the vehicle hitch technological deficiency that patent formerly can not be locked some vehicles.

For achieving the above object, the utility model adopts following technical scheme:

A kind of hitch hook neck locking antihunting device of rolling stock, comprise plate, swash plate, hinge, side plate, high-strength nut and high strength bolt, described plate is square, high swash plate outside in the top of square plate is provided with, hanging down, rear side is provided with the inclined-plane in the bottom of plate, the bottom, both sides of plate connects the upper inner of biside plate respectively by hinge, front end medial surface bottom at two side plates is fixedly connected with high-strength nut respectively, and the high-strength nut of two side plate bottoms of two high strength bolt difference wire connections forms the hitch hook neck locking antihunting device of rolling stock.

The hitch hook neck locking antihunting device of described rolling stock, square plate and swash plate are set to one.

The hitch hook neck locking antihunting device of described rolling stock, both sides, plate bottom bonded assembly biside plate is at least one hinge of every side.

The hitch hook neck locking antihunting device of described rolling stock, described hinge is connected with side plate with plate by welding.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The hitch hook neck locking antihunting device of rolling stock described in the utility model, by plate being inserted hook tail top and coupling for land vehicle, swash plate by plate top withstands on the coupling for land vehicle, the bottom surfaces of plate withstands on hook tail top and forms tight grafting form, side plate with plate two side lower parts withstands on the inside face of coupling for land vehicle both sides then, makes the front end of high strength bolt withstand on the antihunting that hitch is realized in hook tail both sides by high strength bolt and high-strength nut after fastening; The utility model is for formerly applying for a patent (the hitch antihunting latching device of name of patent application, a kind of rolling stock; Application number, 201020156124.6; The applying date, on April 13rd, 2010) technological improvement, the hitch that can adapt to the other parts vehicle is fixed, actv. has overcome the drawback that patent (201020156124.6) formerly can not be locked some vehicle vehicle hitches, for the application of railway breakdown hitch jacking system is laid a good foundation; For with the shortest time, work the car vehicle of answering a pager's call, repair circuit, guarantee the open-minded rapidly of railway main track, station throat track switch, make railway transportation unimpeded, the minimizing accident is reduced to bottom line with causality loss and has got the time the interference and the influence of whole railway transportation.
