Den foreliggende opfindelse angår et bomaggregat med en bom, der kan drejes omkring en lodret drejningsaksel og med en til automatisk åbning og lukning af bommen indrettet mekanisme med bærerulle hvilende på 10 en stationær kambane, der har et laveste punkt, som bestemmer bommens hvilestilling svarende til dens lukkede stilling, og som er opadstigende i det mindste fra den ene side af nævnte punkt, således at bommen ved svingning til den ene side fra lukkestillin-15 gen under indvirkning af sin vægt tilbageføres til den lukkede stilling ved, at bærerullen ruller ned ad kambanen, og et anslag, der er forskydelig mellem en stiling i bærerullens bane langs kambanen, i hvilken stilling det muliggør bærerullens bevægelse over an-20 slaget i retning bort fra hvilestillingen, men hindrer bærerullen i at vende tilbage til hvilestillingen, og en anden stilling, hvor anslaget i det væsentlige befinder sig uden for bærerullens bane for at muliggøre bærerullens bevægelse tilbage over kam-25 banen til hvilestillingen.BACKGROUND OF THE INVENTION The present invention relates to a boom assembly having a boom that can be rotated about a vertical pivot shaft and having a support roll mechanism for automatically opening and closing the boom resting on a stationary cam track having a lowest point which determines the boom resting position corresponding to its closed position, which rises at least from one side of said point, so that the boom, when pivoted to one side from the closing position, under its weight, is returned to the closed position by the carrier roller rolling down the cam, and a stop slidable between a post in the web of the carrier roll along the cam, in which position it allows the carrier roll to move over the impact away from the resting position, but prevents the carrier roll from returning to the resting position, and another position wherein the stop is substantially outside the path of the carrier roll to allow the carrier roll to move back over the cam 25 to the rest position.
I engelsk patent nr. 481.285 beskrives en bom af ovennævnte art, der kan svinges til den åbne stilling ved, at den skubbes til side af et køretøj, der pres-30 ser bommen og derefter automatisk svinger tilbage til lukkestillingen, når køretøjet har passeret gennem bomåbningen. Ved dette kendte bomaggregat har anslaget en drejelig kam. Under bommens åbningsbevægelse bevæger rullen sig på kammen fra den ene side af den- DK 152025 B! j i 2 ! i j nes drejningsakse, og så drejer kammen, når bommen tilnærmelsesvis er i en 45° stilling, for at tillade rullen at bevæge sig nedad over kammen på den anden i side af drejningsaksen, hvorved bommen bevæges til i 5 den åbne stilling. Derpå vender bommen tilbage til j den lukkede stilling ved, at anslaget fjernes fra : rullens bane.British Patent No. 481,285 discloses a boom of the above type that can be swung to the open position by being pushed aside by a vehicle pressing the boom and then automatically swung back to the closing position when the vehicle has passed through bomåbningen. At this known boom assembly, the stop has a swivel comb. During the opening movement of the boom, the roller moves on the cam from one side of it - DK 152025 B! j i 2! in the one axis of rotation, and then the cam rotates when the boom is approximately in a 45 ° position to allow the roller to move downwardly over the cam on the other side of the axis of rotation, thereby moving the boom into the open position. Then the boom returns to j the closed position by removing the stop from: the roll path.
iin
Det er en ulempe ved denne kendte bom, at den alt for ! 10 hurtigt går tilbage til lukkestillingen, således at der vil være risiko for, at det gennem bomåbningen passerende køretøj glider med siden mod bommen, så at j denne kan gribe fast i køretøjet eller beskadige dette.It is a disadvantage of this well-known boom that it too! 10 quickly returns to the closing position, so that there will be a risk of the vehicle passing through the boom opening sliding sideways against the boom so that it can grab or damage the vehicle.
1515
Med det formål at undgå denne ulempe og frembringe en bom med forsinket tilbagegang, således at bommen vil j forblive i sin åbne stilling i det tidsinterval, der i i kræves for køretøjet at passere bomåbningen, går den i 20 foreliggende opfindelse ud på at angive et bomaggre- j gat af ovennævnte art udformet som angivet i den ken- j detegnende del af krav 1. j iIn order to avoid this disadvantage and to produce a retarded boom, so that the boom will remain in its open position during the time interval required by the vehicle to pass the boom opening, the present invention is to provide a boom carrier. - j gat of the aforementioned kind configured as specified in the characterizing part of claim 1. ji
Opfindelsen forklares nærmere i det følgende under j 25 henvisning til tegningen, hvor fig. 1 viser set fra siden et bomaggregat ifølge opfindelsen og 30 fig. 2 i større målestok og i perspektiv anordningen ifølge opfindelsen.The invention is explained in more detail below with reference to the drawing, in which fig. 1 is a side view of a boom assembly according to the invention and FIG. 2 on a larger scale and in perspective the device according to the invention.
Den i fig. 1 viste bom udgøres af en rørkonstruktion 10, der ved hjælp af et lodret rør 11 er lejret på en 3The FIG. 1 is constituted by a pipe structure 10, which is mounted on a 3 by means of a vertical pipe 11
DK 152025BDK 152025B
bomstolpe 12. Bommen har endvidere lodrette rør 13 med passende indbyrdes afstand, således at et køretøj, der kører frem mod bommen, med sine kofangere kan ramme disse rør på bommen og føre denne bort fra 5 lukkestillingen, når køretøjet kører gennem bomåbningen.boom post 12. The boom further has vertical tubes 13 at a suitable distance from one another, so that a vehicle traveling towards the boom can with its bumpers hit these tubes on the boom and move it away from the closing position as the vehicle travels through the boom opening.
Som vist i fig. 2 er bomrøret 11 lejret på den rørformede bomstolpe 12 ved hjælp af lejebøsninger 14 10 anbragt ved den øvre og nedre ende i røret 11 og eventuelt også et eller flere steder herimellem.As shown in FIG. 2, the boom pipe 11 is mounted on the tubular boom post 12 by means of bearing bushings 14 10 arranged at the upper and lower ends of the pipe 11 and optionally also one or more places therebetween.
Bomrøret 11 er ikke alene drejeligt, men også lodret forskydeligt på bomstolpen 12, og en eller flere smø-renipler 15 er anbragt for smøring af lejerne mellem 15 bomrør og bomstolpe, således at røret løber nemt på bomstolpen. Bomrøret 11 er foroven aflukket med et dæksel 16, der kan være fastgjort med et låseorgan 17 eller lignende.The boom pipe 11 is not only rotatable, but also vertically displaceable on the boom post 12, and one or more butterfly nipples 15 are arranged for lubricating the bearings between the boom boom and boom post, so that the tube runs easily on the boom post. The boom pipe 11 is closed at the top with a cover 16 which may be secured with a locking means 17 or the like.
20 På indersiden af bomrøret 11 er drejeligt lejret en bærerulle 18 i form af en kuglelejering med akseltap 19, som ved en skrueforbindelse 20 er fastgjort til bomrøret. Skrueforbindelsen dækkes udvendigt af en pladekappe 21. Bærerullen 18 er anbragt i en åbning 25 22 i bomstolpen 12, og denne åbnings nedre kant dan ner en kambane 23, som er opadstigende fra den stilling, hvori bærerullen 18 er vist til højre i fig. 2 i retning af pilen 24. Den nævnte stilling af bærerullen 18 svarer til den lukkede stilling af bommen 30 10.20 On the inside of the boom pipe 11 is pivotally mounted a support roller 18 in the form of a ball bearing with shaft pin 19, which is secured to the boom pipe by a screw connection 20. The screw connection is covered externally by a plate sheath 21. The carrier roller 18 is arranged in an opening 25 22 in the boom post 12, and the lower edge of this opening forms a cam track 23 which rises upward from the position in which the carrier roller 18 is shown to the right in FIG. 2 in the direction of arrow 24. Said position of the carrier roll 18 corresponds to the closed position of the boom 30 10.
Inden i bomstolpen er aksial forskydeligt lejret et rørformet element 25, der styres ikke-drejeligt ved hjælp af en aksialt forløbende fast anbragt skinneInside the boom post is axially displaceable a tubular member 25 which is non-pivotally guided by an axially extending fixed position rail

i i i 4 i i 26. Elementet 25 er ved hjælp af en konsol 27, der på ; sin ydre ende har en bøsning 28, forbundet med en stempelstang 29 til en hydraulisk cylinder 30 ved hjælp af en skrueforbindelse 31, og cylinderen 30 er 5 ved sin øvre ende fastgjort til en ring eller plade 32, der igen er fastholdt i bomstolpen 12 ved hjælp j af en skrueforbindelse 33. Hydraulikcylinderen 30 er j af den art (støddæmper), som har en fjeder, der på- j i virker hydraulikcylinderens stempel i den ene retning j 10 - i det foreliggende tilfælde svarende til stempel- ! stangens 29 forskydning opad. Endvidere har hydrau- j likcylinderens 30 stempel en ventilreguleret forbindelse mellem de på begge sider af stemplet med hydraulikvæske fyldte cylinderrum og således udformet, 15 at væsken let kan passere mellem stemplets to sider, når dette forskydes opad under indvirkning af fjede- j ren, medens væskestrømmen drøvles, når stemplet mod fjederens indvirkning forskydes nedad i cylinderen.The element 25 is by means of a bracket 27 which on; its outer end has a bushing 28 connected to a piston rod 29 to a hydraulic cylinder 30 by means of a screw connection 31, and the cylinder 30 is attached at its upper end to a ring or plate 32 which is again retained in the boom post 12 by aid j of a screw connection 33. The hydraulic cylinder 30 is j of the type (shock absorber) having a spring which also acts on the piston of the hydraulic cylinder in one direction j 10 - in the present case corresponding to the piston! bar 29 displacement upward. Furthermore, the piston of the hydraulic cylinder 30 has a valve-regulated connection between the cylinder compartments filled on both sides of the piston with hydraulic fluid 15, so that the liquid can easily pass between the two sides of the piston when it is displaced upwards under the action of the spring, while the fluid flow is swirled as the plunger against the action of the spring is displaced downward in the cylinder.
i 20 Elementet 25 danner en kam 34 med en jævnt skrånende kamflade 35 og en stejlere kamflade 36 og ved påvirkning af fjederen i hydraulikcylinderen 30 befinder denne kam sig i bærerullens 18 bevægelsesbane langs kambanen 23, som vist i fig. 2, idet kammen 34 skyder 25 op fra kambanen 23 som en næse. Kammen holdes i denne stilling af fjederen, og den kan kun langsomt trykkes nedad fra denne stilling imod fjederens indvirkning, i da den drøvlede strømning af hydraulikvæsken mellem j stemplets modsatte sider hæmmer denne nedtrykning.In the element 25, a cam 34 forms an evenly sloping cam surface 35 and a steeper cam surface 36, and when actuated by the spring in the hydraulic cylinder 30, this cam is in the path of movement of the carrier roll 18 along the cam web 23, as shown in FIG. 2, with the cam 34 projecting 25 from the cam 23 as a nose. The cam is held in this position by the spring and it can only be slowly pushed downward from this position against the action of the spring, as the swirled flow of the hydraulic fluid between the opposite sides of the piston inhibits this depression.
30 Stemplet har tilstrækkelig stor slaglængde til at kammen vil kunne trykkes tilstrækkeligt langt ned til at befinde sig i højde med kambanen 23 eller i det mindste til en stilling, hvor den kun rager ubetydeligt op over denne kambane. Når trykket mod kammen 34 5The piston has a sufficiently long stroke to allow the cam to be pushed far enough to be at the height of the cam 23 or at least to a position where it only extends slightly above that cam. When pressed against the cam 34 5

ophører, vil den hurtigt gå tilbage til den viste stilling under indvirkning af fjederen i hydraulikcylinderen 30, da væsken i dette tilfælde hurtigt kan passere fra den ene side af stemplet til den anden 5 side.cease, it will quickly return to the position shown under the action of the spring in the hydraulic cylinder 30, since in this case the liquid can pass rapidly from one side of the piston to the other 5 side.
Når kammen svinges imod den åbne stilling som angivet med pilen i fig. 1 ved, at et køretøj kører imod bommen og forskyder denne, medfører det, at bærerullen 10 18 ruller i den med pilen 24 angivne retning og her ved løftes op fra kambanen 23 ved at rulle op på banen 36 på kammen 34, for derpå langs banen 25 atter at rulle ned på kamfladen 23. Under denne bevægelse vil bommen således ved lodret forskydning af bomrøret 15 11 på bomstolpen 12 løftes, og da olien i hydraulik cylinderen 30 på grund af drøvling i den ventilregulerede åbning i stemplet hæmmer kammens 34 nedadbevæ-gelse, vil denne ikke blive nedtrykket under bærerullens 18 bevægelse hen over denne. En mindre nedtryk-20 ning vil naturligvis forekomme ved rullens passage, men denne vil være uden betydning. Bærerullen 18 vil derfor fastholdes af kammen 34 på den side, hvor kamfladen 35 er anbragt og indtage den med stiplede linier viste stilling 18 , hvor bommen er helt åben 25 og således dreje i det væsentlige 90° eller fortrinsvis mere end 90° bort fra den i fig. 1 viste stilling. Efter at bærerullen 18 har passeret toppen af kammen 34, vil den under påvirkning af bommens vægt rulle ned ad kamfladen 35, således at bommen, uden at 30 køretøjet nødvendigvis påvirker denne, automatisk svinges til den helt åbne stilling. Denne automatiske udsvingning kan påbegyndes, efter at bommen er drejet 45-60°. Hvilende mod kambanen 23 og kamfladen 35 vil bærerullen 18 i stillingen 18 udøve et af bommensWhen the cam is pivoted toward the open position as indicated by the arrow in FIG. 1 in that a vehicle drives against the boom and displaces it, causing the carrier roller 10 18 to roll in the direction indicated by the arrow 24 and hereby being lifted up from the cam track 23 by rolling up the track 36 on the cam 34, then along The web 25 again rolls down on the cam surface 23. During this movement, the boom will thus be lifted by vertical displacement of the boom pipe 11 11 on the boom post 12, and as the oil in the hydraulic cylinder 30 due to throttling in the valve-regulated opening in the piston inhibits the downward movement of the cam 34. This will not be depressed during the movement of the carrier roll 18 over it. Of course, a minor depression will occur at the passage of the roll, but this will be of no significance. The support roller 18 will therefore be held by the cam 34 on the side where the cam surface 35 is positioned and take the dotted line position 18, where the boom is fully open 25 and thus rotate substantially 90 ° or preferably more than 90 ° away from the cam. in FIG. 1. After the carrier roll 18 has passed the top of the cam 34, it will, under the weight of the boom, roll down the cam surface 35, so that the boom, without necessarily affecting the vehicle, automatically swings to the fully open position. This automatic oscillation can be started after the boom is turned 45-60 °. Resting against the cam track 23 and the cam surface 35, the carrier roll 18 in position 18 will exert one of the boom

6 vægt betinget tryk mod kammen 34, hvorved denne i det omfang, som betinges af hydraulikvæskens strømning mellem stemplets to sider gennem den neddrøvlede åbning i stemplet, langsomt bevæger sig nedad mod virk-5 ningen af den i cylinderen 30 anbragte fjeder, hvorved kammen 34 efterhånden når til en stilling, hvor bærerullen 18 kan rulle langs kambanen 23 tilbage til den med fuldt optrukne linier i fig. 2 viste stilling. Ved en hensigtsmæssig tilpasning af drøvlingen 10 i stemplet samt hældningsvinklerne på kambanen 23 og kamfladen 35 i forhold til bommens vægt kan man på ønsket måde indstille den tid, som det tager for bommen at nedtrykke kammen 34, når bommen befinder sig i den åbne stilling, så at bommen herefter kan svinge 15 tilbage i lukkestillingen. Såsnart bærerullen 18 har passeret forbi den nedtrykkede kam 34 under bommens vej fra den åbne til den lukkede stilling, vil fjede- : j ren i hydraulikcylinderen 30 hurtigt kunne trykke j i kammen 34 op til den i figuren viste stilling, da en 20 sådan bevægelse ikke i nævneværdig grad bremses af væsken i hydraulikcylinderen. Bommen er herefter klar til påny at åbnes på den ovenfor beskrevne måde.6 weight conditional pressure on the cam 34, to the extent dictated by the flow of the hydraulic fluid between the two sides of the piston through the drooped opening in the piston, slowly moves downwardly against the action of the spring arranged in the cylinder 30, whereby the cam 34 gradually reaching a position where the carrier roll 18 can roll along the cam track 23 back to the fully drawn lines of FIG. 2. By appropriately adjusting the throttle 10 in the piston as well as the angles of inclination of the cam web 23 and cam surface 35 relative to the weight of the boom, it is desirable to adjust the time taken for the boom to depress the cam 34 when the boom is in the open position. so that the boom can then swing 15 back into the closing position. As soon as the carrier roller 18 has passed past the depressed cam 34 during the boom path from the open to the closed position, the spring in the hydraulic cylinder 30 will be able to quickly push the cam 34 up to the position shown in the figure, since such a movement does not to a considerable extent, the fluid in the hydraulic cylinder is braked. The boom is then ready to be opened again in the manner described above.
Det vil forstås, at der ved anordningen ifølge den 25 foreliggende opfindelse opnås dels en automatisk drejning af bommen til åben stilling, efter at drejningen er påbegyndt ved, at et køretøj kører mod bommen og drejer denne, dels en sikker tilbageholdelse af bommen i den åbne stilling, før den med en forsin- j 30 kelse vil gå tilbage til lukkestillingen. Det er end- .It will be appreciated that the device according to the present invention achieves in part an automatic rotation of the boom to the open position after the rotation is started by a vehicle moving towards the boom and turning it, and in part a secure retention of the boom in the open position. position before it will return to the closing position with a delay. It is end-.

Den ovenfor beskrevne anordning tillader kun, at bommen svinges til den ene side, men det vil forstås, at man ved at forsyne elementet 25 med to diametralt modsatte kamme 34 og gøre åbningen 22 i bomstolpen 5 tilstrækkelig stor til, at bommen kan svinges til den ene eller den anden side fra hvilestillingen, hvori den er lukket, og kunne fastholdes med forsinket tilbagegang, uanset til hvilken side bommen svinges. Det samme element 25 og samme hydrauliske cylinder 30 kan 10 styre forsinkelsen til begge sider.The device described above only allows the boom to be pivoted to one side, but it will be understood that by providing the element 25 with two diametrically opposed ridges 34 and making the opening 22 of the boom post 5 large enough for the boom to be pivoted to it. one or the other side from the resting position in which it is closed and could be retained with delayed decline, regardless of which side the boom is swung. The same element 25 and the same hydraulic cylinder 30 can control the delay on both sides.
Det vil forstås, at opfindelsen ikke er begrænset til den ovenfor beskrevne udførelsesform, men at forskellige ændringer vil være mulig inden for opfindelsens 15 rammer. Dette gælder eksempelvis anbringelse af hydraulikcylinderen 30, der ved den beskrevne udførelsesform er ophængt, men også kan anbringes stående inden i bomstolpen 12. Man vil også kunne lade cylinderen 30 forskydes sammen med elementet 25, medens 20 stempelstangen 29 er fast anbragt i bomstolpen 12.It will be understood that the invention is not limited to the embodiment described above, but that various changes will be possible within the scope of the invention. This applies, for example, to the placement of the hydraulic cylinder 30, which in the described embodiment is suspended, but can also be placed standing inside the boom post 12. It is also possible to allow the cylinder 30 to be displaced together with the element 25, while the piston rod 29 is fixedly mounted in the boom post 12.
Elementet 25 kan også udformes på forskellig måde, men den beskrevne rørformede udførelsesform er at foretrække under hensyn til, at styringen af elementet herved kan udformes på forholdsvis enkel måde. Fjede-25 ren kan være anbragt uden for cylinderen i stedet for at være placeret inden i denne som i den ovenfor beskrevne udførelsesform.The element 25 can also be designed in different ways, but the described tubular embodiment is preferred, in that the control of the element can thereby be designed in a relatively simple manner. The spring may be disposed outside the cylinder instead of being located within it as in the embodiment described above.
