Zavihtljiva streha za železniški tovorni vagon, ki je s strani čelne stene podprta na nosilnih rokahSwivel roof for freight wagon supported by load-bearing arms on the front wall

Izum se nanaša na zavihtljivo streho za železniški tovorni vagon, ki je s strani čelne stene podprta na nosilnih rokah, pri čemer nakladalni prostor vagona sestoji iz vsaj dveh lijakastih komor in pri čemer je zavihtljiva streha iz zaprtega položaja s pomočjo sprožilnega organa zavihtljiva proti sili vzmeti k vzdolžni strani vozila.The invention relates to a swinging roof for a freight wagon supported by the front wall on the supporting arms, the loading space of the wagon being at least two funnel chambers and the swinging roof being closed from the closed position by means of a triggering body which is swinging against the force of the spring to the longitudinal side of the vehicle.

Izvedbe zavihtljivih streh za železniške tovorne vagone se da v osnovi razdeliti v dve vrsti. Pri prvi vrsti se zavihtljivo streho pred zavihtitvijo in s tem posledično pred odprtjem nakladalnega prostora dvigne preko njenih nosilnih rok, ki so podprte s čelne strani, in zatem zavihti k vzdolžni strani vagona. Te dvigljive in zavihtljive strehe so uporabljene le za posebna tovorna vozila in za posebne tovore, kajti sprožilni mehanizem streh je zapleten in drag.The designs of swinging roofs for freight wagons can be basically divided into two types. In the first instance, the swinging roof is raised before turning and, consequently, before opening the loading compartment, it rises over its supporting arms, which are supported from the front, and then swung to the longitudinal side of the wagon. These lifting and swiveling roofs are used only for special trucks and special loads, because the trigger mechanism of the roofs is complicated and expensive.

Pri drugi vrsti zavihtljivih streh za železniške tovorne vagone se le-te brez poprejšnjega dvižnega gibanja strehe zavihti neposredno k vzdolžni strani vagona. Takšna zavihtljiva streha je npr. znana iz DE-AS 16 05 043. Pri tej zavihtljivi strehi, ki je s strani čelne stene podprta na nosilnih rokah, se s pomočjo sprožilnega organa leto iz zaprtega položaja zavihti k poljubni vzdolžni strani vozila, pri čemer se pri tej zavihtitvi sproščajočo potencialno energijo vodi k akumulatorski razporeditvi, ki je povezana z obema čelnima stranema zavihtljive strehe, katera to energijo shrani in jo pri zavihtitvi nazaj v zaprt položaj ponovno odda zavihtljivi strehi. Sprožilni organ (ročični pogon) je pri tem s pomočjo vrvi ali verig, vodenih preko obračalnih kolutov, razporejenih na eni čelni strani v bližini zgornje pasnice, povezan s strešno lupino zavihtljive strehe, pri čemer so vrvi ali verige z vključitvijo dolžinskega izravnalnega elementa povezane med seboj oz. s strešno lupino. Pri tej izvedbi se je kot pomanjkljivost pokazala potrebna izravnava gibanja in energije za obe nosilni roki zavihtljive strehe, kar naj bi preprečilo zvijanje zavihtljive strehe pri zavihtitvi le-te, s čimer se izognemo stisnitvi in neenakomerni zavihtitvi vzdolžnih koncev strehe. Te izravnalne naprave so zapletene in negospodarne ter vsebujejo občutljive gradbene dele.In the second type of swivel roofs for freight wagons, they swing directly to the longitudinal side of the wagon without prior movement of the roof. Such a swinging roof, for example. known from DE-AS 16 05 043. With this swinging roof, supported by the front wall on the supporting arms, with the help of the actuator, the year from the closed position is rotated to any longitudinal side of the vehicle, thus releasing the potential energy leads to an accumulator arrangement that is connected to both front faces of the swivel roof, which stores this energy and, when swung back to the closed position, re-transmits the swivel roof. The actuator (crank actuator) is connected to the roof shell of the swivel roof by means of ropes or chains guided through rotating discs arranged on one front near the upper lane, the ropes or chains being connected by a length compensating element themselves or. with a roof shell. In this embodiment, the required balance of movement and energy for both bearing arms of the swivel roof was shown to be a disadvantage, which was to prevent the swivel of the swivel from twisting when it was swung, thereby avoiding compression and uneven swirling of the longitudinal ends of the roof. These leveling devices are complex and uneconomical and contain delicate construction parts.

Naloga predloženega izuma sestoji v tem, da se za zavihtljive strehe uvodoma omenjene vrste najde sprožilno napravo, ki z enostavnimi sredstvi zagotavlja zavihtitev zavihtljive strehe brez zvijanja in gospodarno ter neobčutljivo konstrukcijo.It is an object of the present invention to provide a trigger device for swinging roofs of the aforementioned type which, by simple means, provides for a swinging of the swinging roof without twisting and economical and insensitive construction.

To nalogo se po izumu reši s tem, da sprožilni organ sestoji iz približno v vzdolži sredi na zavihtljivi strehi pritrjenega vzvoda, kije s svojim drugim koncem zgibno uležajen na ogrodju železniškega tovornega vagona in za zavihtitev zavihtljive strehe fluidno obremenljiv s pogonom. Pri tem je vzvod zasnovan kot kotni vzvod in približno kot črka Z, pri čemer je v ogrodju železniškega tovornega vagona uležajen v prečni sredi le-tega. Pogon prednostno sestoji iz hidravličnega valja, ki je s svojim prvim koncem zgibno uležajen na vzvodu, s svojim drugim koncem pa prav tako zgibno na ogrodju vagona. Po drugem izvedbenem primeru izuma sestoji pogon iz mehanskega gonila. Prednostno je nadalje na vzvodu zgibno pritrjena vlečna vzmet, ki je približno nasproti pogonu delujoče prav tako zgibno uležajena na ogrodju vagona. Ležaji nosilnih rok zavihtljive strehe in ležaj vzvoda v ogrodju vagona so poravnano razporejeni v eni ravnini.This task is solved according to the invention by the fact that the actuating body consists of approximately in the middle in the middle of the pivoting roof of the fixed lever, which with its other end is articulated on the frame of the railway freight wagon and for the rotation of the swinging roof fluidly loadable by the actuator. In this case, the lever is designed as an angular lever and approximately as the letter Z, with the bearing in the frame of the rail freight wagon resting in the transverse middle of it. The actuator preferably consists of a hydraulic cylinder which, with its first end, is articulated on the lever and its second end also articulately on the frame of the wagon. According to another embodiment of the invention, the drive consists of a mechanical gearbox. Preferably, a drawbar spring is attached to the lever, which is also pivotally mounted on the wagon frame approximately opposite to the drive. The bearings of the load arms of the swivel roof and the lever bearing in the wagon frame are aligned in a single plane.

Z izumom se na prednosten način najde pogon za zavihtljivo streho za železniške tovorne vagone, ki se odlikuje po majhnem številu gradbenih elementov, ki je neobčutljiv in pred poškodbami varovano razporejen v ogrodju vagona, in ki z razporeditvijo sprožilnega organa po izumu na zavihtljivi strehi zagotavlja enakomerno zavihtitev brez zvijanja zavihtljive strehe. Zapleteni gradbeni elementi za enakomeren tek vzdolžnih koncev zavihtljive strehe niso potrebni.The invention preferably provides a swinging roof drive for railway freight wagons, characterized by a small number of building elements, insensitive and securely arranged in the wagon frame, and which ensures a uniform distribution of the actuator according to the invention on the swinging roof. swivel without twisting the swivel roof. Intricate construction elements are not required for a smooth running of the long ends of the swinging roof.

Detajli izuma so pobliže pojasnjeni s pomočjo izvedbenega primera v načrtu, kjer kaže sl. 1 železniški tovorni vagon z zavihtljivo streho po izumu v stranskem pogledu, sl. 2 železniški tovorni vagon s sl. 1 v pogledu s čela, sl. 3 prerez po črti ΙΠ-III s sl. 1, z zavihtljivo streho v zaprtem položaju, sl. 4 prerez po sl. 3, z zavihtljivo streho v odprtem položaju.The details of the invention are explained in greater detail by way of an exemplary embodiment in the outline where FIG. 1 is a side view rail freight wagon with a swivel roof, FIG. 2 is a railway freight wagon of FIG. 1 in forehead view, FIG. 3 is a cross-section along line ΙΠ-III of FIG. 1, with a swinging roof in the closed position; 4 is a sectional view according to FIG. 3, with swinging roof in open position.

Nakladalni prostor na načrtu predstavljenega železniškega tovornega vagona sestoji iz dveh medsebojno ločeno razporejenih, lijakastih komor 1, ki se jih da raztovoriti preko stranskih razkladalnih loput 2. V vzdolžni sredi vagona je v železniškem tovornem vagonu razporejeno prečno sedlo 3. Nakladalna odprtina 4 v zgornjem temenu železniškega tovornega vagona je pokrita z zavihtljivo streho 5, ki je na svojih vzdolžnih koncih preko nosilnih rok 6 zavihtljivo uležajena na čelnih stenah 7 železniškega tovornega vagona. Nosilni roki 6 sta pri tem zgibno uležajeni v ležajih 8 na čelnih stenah 7 in sta togo povezani z vzdolžnima koncema zavihtljive strehe 5. V vzdolžni sredi zavihtljive strehe 5 je na prvi vzdolžni strani le-te togo razporejen vzvod 9, ki kot črka Z kolenasto pregiban štrli v prečno sedlo 3 železniškega tovornega vagona in je v njegovi prečni sredi zgibno uležajen v ležaju 10. Na vzvod 9 prijemlje zgibno v ležaju 11 uležajen, iz hidravličnega valja sestoječ pogon 12, ki je s svojim drugim koncem prav tako zgibo uležajen v ležaju 13 železniškega tovornega vagona. Približno nasproti pogonu 12 delujoče je preko ležaja 14 na vzvodu 9 zgibno pritrjena vlečna vzmet 15, kije s svojim drugim koncem pritrjena na prečnem sedlu 3 železniškega tovornega vagona.The loading space on the layout of the presented freight wagon consists of two separately arranged, funnel chambers 1, which can be unloaded via lateral unloading flaps 2. In the longitudinal center of the wagon, a transverse saddle 3 is arranged in the freight wagon. the freight wagon is covered by a swivel roof 5 which, at its longitudinal ends, is pivotally mounted on the front walls 7 of the freight wagon through its supporting arms 6. The supporting arms 6 are thus articulated in the bearings 8 on the front walls 7 and are rigidly connected to the longitudinal ends of the swivel roof 5. In the longitudinal middle of the swivel roof 5, there is a rigidly arranged lever 9, which, with the letter Z, is elongated. it folds into the transverse fifth wheel of the rail freight wagon and is articulated in its transverse center in the bearing 10. The drive 9, which is articulated in the hydraulic cylinder 12, is mounted on the lever 9, which, with its other end, is also articulated in the bearing 13 rail freight wagon. Approximately opposite to the actuator 12, a traction spring 15 is pivotally actuated via a bearing 14 at the lever 9, which is secured to its transverse saddle 3 by a railway freight wagon with its other end.

Za zavihtitev zavihtljive strehe 5 se fluidno obremeni hidravlični valj (pogon 12), ki zavihti zavihtljivo streho 5 k vzdolžni strani vagona. Pri tej zavihtitvi se napne vzmet 15, ki je dimenzionirana tako, da se pri izpadu hidravlike zavihtljivo streho 5 s silo vzmeti 15 zavihti nazaj v zaprti položaj.To swivel the swivel roof 5, a hydraulic cylinder (actuator 12) is fluidly loaded, which swings the swivel roof 5 towards the side of the wagon. In this turn, the spring 15 is tensioned, which is dimensioned so that, in the event of a failure of the hydraulic system, the swivel roof 5 is forced back into the closed position by force of the spring 15.

Zavihtljiva streha 5 je nasproti nakladalni odprtini 4 železniškega tovornega vagona tako zatesnjena s tesnili, ki niso bistvo izuma, da se prepreči vdiranje vlage in letečega snega.The swinging roof 5 is sealed against the loading opening 4 of the freight wagon with seals that are not the essence of the invention to prevent moisture and flying snow from entering.

S središčnim prijemom vzvoda 9 na zavihtljivi strehi 5 se lahko odpovemo dodatnim napravam za enakomerni tek na nosilnih rokah 6 zavihtljive strehe 5.By centrally gripping the lever 9 on the swinging roof 5, additional devices for even running on the supporting arms 6 of the swinging roof 5 can be released.
