Abstract
Description
Oppfinnelsen angår krankjøretøy, spesielt bergepanser med et krananlegg. På slike kjøretøy, som løfter og flytter tung last på krankroken, og som også arbeider på ujevnt eller mykt underlag, er det nødvendig med overvåkning av standstabiliteten. The invention relates to crane vehicles, in particular recovery vehicles with a crane system. On such vehicles, which lift and move heavy loads on the crane hook, and which also work on uneven or soft ground, it is necessary to monitor the stability of the stand.
Bakgrunn Background
Generelt må det unngås, at kjøretøykranen velter ved stor last og langt utsvingt kranutligger. Til derte formålet benyttes en kjent lastmomentbegrenser, som avgir varselmeldinger avhengig av last og utsvingning, eller i noen tilfeller sogar kopler ut kranen. In general, it must be avoided that the vehicle crane overturns in the event of a large load and a far-swinging crane jib. For that purpose, a known load torque limiter is used, which emits warning messages depending on the load and fluctuation, or in some cases even disconnects the crane.
Ved løfteanordninger, så som krananlegg, er det også påbudt å installere beskyttelsesinnretninger som forhindrer fare for personer og material. Disse innretningene begrenser for det første en mulig overbelastning og for det andre blir en såkalt "konturbegrensning" overholdt, for ikke å sette redskapen og operatøren i fare. In the case of lifting devices, such as crane systems, it is also mandatory to install protective devices that prevent danger to people and material. These devices, firstly, limit a possible overload and, secondly, a so-called "contour limitation" is observed, so as not to put the implement and the operator at risk.
Spesielt krananlegg på mobile understell, som avhengig av anvendelsessted har forskjellig standundertag, er helt avhengige av disse lastmomentbegrenseme (LMB), for ikke å sette standstabiliteten i fare. LMB overvåker de fysiske betingelsene (hydrauliske trykk, mekaniske avstander og spenninger m.m.) til et krananlegg under bruk. In particular, crane systems on mobile chassis, which depending on the place of use have different stand underroofs, are completely dependent on these load moment limiters (LMB), so as not to endanger stand stability. LMB monitors the physical conditions (hydraulic pressures, mechanical distances and tensions etc.) of a crane system during use.
I teknikken finnes det mange forskjellige forslag for oppførelser og bruk av tippeovervåknings-innretninger. 1 tysk patentskrift 199 18 597 er det for eksempel foreslått en fremgangsmåte som skal redusere veltefaren for kjørende veikjøretøy. In the technique, there are many different proposals for the construction and use of tipping monitoring devices. 1 German patent document 199 18 597, for example, a method is proposed which should reduce the risk of overturning for running road vehicles.
I tysk patentskrift 34 34 689 blir et veltevarslingsinstrument beskrevet, som ved hjelp av et lite rør fyllt med kvikksølv, gir et sjaltesignal for en varselmelding ved en helning av kjøretøyet tilsvarende en veltevinkel. In German patent document 34 34 689, a rollover warning instrument is described, which by means of a small tube filled with mercury, gives a switching signal for a warning message when the vehicle leans corresponding to a rollover angle.
Fra tysk patentskrift 42 36 328 er det kjent en kombinert akselerasjons- og helningssensor, som ved helning eller akselerasjon gir ut et størrelsésavhengig sjaltesignal ved hjelp av et antall kontaktpunkter. From German patent document 42 36 328, a combined acceleration and inclination sensor is known, which in case of inclination or acceleration outputs a size-dependent switching signal by means of a number of contact points.
I tysk patentskrift 42 17 247 er det beskrevet en helningssensor etter prinsippet til en dempet pendel, for overvåkning av et fartøys helning. German patent document 42 17 247 describes an inclination sensor based on the principle of a damped pendulum, for monitoring the inclination of a vessel.
Formål Purpose
Oppfinnelsens oppgave er å forbedre en kjent lastmomentbegrenser på en slik måte at den imøtekommer økte sikkerhetskrav, der The task of the invention is to improve a known load torque limiter in such a way that it meets increased safety requirements, where
- et feiltilfelle eller utfall av den eksisterende LMB-en ikke fører til velt av kranen, - a failure or failure of the existing LMB does not lead to the overturning of the crane,
- begynnelsen av en velt blir tidsnok observert og - the beginning of a rollover is observed in time and
• det skal nås en sikkerhet i samsvar med kategori 3 i DIN 9S4-1. • safety must be achieved in accordance with category 3 of DIN 9S4-1.
Denne oppgaven løses i samsvar med oppfinnelsen ved de karakteristiske kjennetegnene i patentkrav 1. Videre kjennetegn angis i de uselvstendige kravene. This task is solved in accordance with the invention by the characteristic features in patent claim 1. Further features are specified in the non-independent claims.
Oppfinnelsen The invention
En ekstra standstabilitetsovervåkning med en ekstra giver og videre driftsti I stands- og styringselementer blir i samsvar med oppfinnelsen innsatt sammen med den kjente lastmomentbegrenseren og en styringsenhet og et test- og kontrollsystem. An additional position stability monitoring with an additional sensor and further operating path I position and control elements are, in accordance with the invention, inserted together with the known load torque limiter and a control unit and a test and control system.
Fordelene ved oppfinnelsen består i at sikkerheten ved det mobile krananlegget. og dermed vernet mot ulykker for operatør og utstyr, blir vesentlig forbedret. The advantages of the invention consist in the safety of the mobile crane system. and thus the protection against accidents for the operator and equipment, is significantly improved.
Eksempel Example
Et utførelseseksempel av oppfinnelsen er skjematisk fremstilt i tegningen og blir i det følgende nærmere beskrevet. Her viser: An embodiment of the invention is shown schematically in the drawing and is described in more detail below. Here shows:
Fig. 1: et prinsippbilde med ekstra overvåkning. Fig. 1: a principle view with additional monitoring.
Fig. i viser en kjent lastmomentbegrenser 1, som er koplet sammen med en ekstra standstabilitetsovervåkning 2, et test- og kontrollsystem 3 og en styringsenhet 4. Den ekstra overvåkningen 2 har en egen vaklevinkelgiver 7, som arbeider uavhengig av lastmomentbegrenserens givere 6, og en styringsutgang 8, som kan kople ut kranhydraulikken. En klarmelding 9 og en varselmelding 10 blir også styrt av overvåkningen 2. En uavhengig batteristrømforsyning 11 forsyner overvåkningen 2, og andre meldingsinnganger 12 blir innmatet for overvåkning. Fig. i shows a known load moment limiter 1, which is connected together with an additional stability monitoring 2, a test and control system 3 and a control unit 4. The additional monitoring 2 has its own wobble angle encoder 7, which works independently of the load torque limiter's encoders 6, and a control output 8, which can disconnect the crane hydraulics. A ready message 9 and a warning message 10 are also controlled by the monitoring 2. An independent battery power supply 11 supplies the monitoring 2, and other message inputs 12 are fed in for monitoring.
Etter innlcopting av kranfunksjonen følger overvåkningens 2 nullpunktsinnstilling med hensyn til vaklevinkelen til kjøretøyet og dermed dets skråstilling. Ved en skråstitling eller vakling på kjøretøyet større enn en fastsatt helnings-grenseverdi, utløses den ekstra overvåkningen, kranhydraulikken koples ut og sentral varsl ingen 10 blir satt på. Denne grenseverdien ligger utenfor den tillatte lastekurven og innenfor veltegrensen. After switching on the crane function, monitoring 2 follows the zero-point setting with regard to the vehicle's sway angle and thus its inclined position. If the vehicle tilts or wobbles greater than a set tilt limit value, the additional monitoring is triggered, the crane hydraulics are switched off and central warning no 10 is activated. This limit value lies outside the permitted load curve and within the tipping limit.
Etter utløsningen og utkoplingen av kranhydraulikken kan kranhydraulikken koples inn igjen for eksempel med en nødbryter og lasten beveges ut av fareområdet av operatøren. After the release and disconnection of the crane hydraulics, the crane hydraulics can be switched back on, for example with an emergency switch, and the load moved out of the danger area by the operator.
Overvåkningen er laget på en slik måte, at den kun utløses når forbudte høye kranlaster ikke oppdages av lastmomentbegrenseren 1. Dette kan skje ved for eksempel driftsutfall av LMB-ens elevasjons-, azimut- eller vaklevinkelgiver. Overvåkningen blir regelmessig kontrollert for feil, slik at det ikke kan oppstå uoppdagete feil. Dette skjer for eksempel ved en LMB-test før anvendelse av kranen. The monitoring is designed in such a way that it is only triggered when prohibited high crane loads are not detected by the load torque limiter 1. This can happen, for example, when the LMB's elevation, azimuth or wobble angle sensor fails. The monitoring is regularly checked for errors, so that no undetected errors can occur. This happens, for example, with a LMB test before using the crane.
