  • the document EP 2727876 A1 proposes a monitoring device for the supporting loads of the support legs of a mobile crane, in which the sum of all supporting loads is to correspond to the total weight of the mobile crane at the end of the supporting process. Furthermore, it is proposed to determine the supporting forces and to balance against each other. For the compensation of the supporting forces a corresponding support force sensor is provided on the support legs.
  • This object is achieved by a mobile large manipulator according to claim 1. Furthermore, this object is achieved by a method for supporting a mobile large manipulator according to claim 13.
  • a mobile large manipulator comprises a chassis, arranged on the chassis, about a vertical axis rotatably arranged ausfalt- and / or extendable work jib, support jib, which are each arranged on the chassis and from a driving position wholly or partially horizontally extendable to a support position and vertically extendable support legs disposed on the outer ends of the support beams and supporting the large manipulator to form a support force.
  • the invention is distinguished, in particular, by a program-controlled support aid, which is set up to determine desired support forces for the individual support legs, taking into account the support position of the support brackets where the chassis of the large manipulator is unsupported in the supported state.
  • the invention is based on the finding that the optimum support forces acting on the individual support legs are heavily dependent on the support position of the support arms, that is, how far the support arms are extended or folded away from the chassis. With only slightly or not extended / folded support arms support forces of the support legs should be much higher in the rule, to avoid distortion of the chassis at the end of the erection process, whereby the supporting forces are optimally distributed to the support legs even when extended boom.
  • the program-controlled support aid is adapted to take into account the center of gravity of the large manipulator for the determination of the support forces. By considering the center of gravity of the large manipulator, the program-controlled support can determine the optimal support forces for the individual support legs particularly accurate.
  • the center of gravity can be fixed, but the support aid is advantageously set up to calculate the position of the center of gravity because, for example, different support positions of the support arms or different loads of the large manipulator shift the center of gravity. Taking into account the actual center of gravity, the desired supporting forces can be determined even more accurately.
  • the Abst Reifen Anlagen is set up for the calculation of the center of gravity of the large manipulator levels of tanks (eg water tank, diesel tank, etc.) to take into account, which again results in an improvement of the determination of the center of gravity, because the levels of the tanks can significantly affect the position of the Have center of gravity of the large manipulator and thus influence the support forces of the individual support legs.
  • the large-scale mobile manipulator comprises sensors for determining the position of the extended support arms in order to take the support configuration into consideration as accurately as possible for the determination of the support forces.
  • the support aid is advantageously set up to use a numerical simulation for determining the support forces, for example a model based on a physical description of the large manipulator, with which the support forces to be set can be simulated.
  • a numerical simulation for determining the support forces for example a model based on a physical description of the large manipulator, with which the support forces to be set can be simulated.
  • a bar model of the large manipulator can be used, on the basis of which the supporting forces are determined with a FEM simulation.
  • a special advantage is provided by an analytical calculation method for determining the supporting forces, because the required computing power, for example, is considerably lower than the numerical simulation mentioned above.
  • the program-controlled support aid is configured to control the vertical extension operation of the support legs and to adjust the support forces for the individual support legs in accordance with the determined support forces.
  • a support force sensor is assigned to each support leg.
  • the large manipulator has a sensor system for detecting the inclination of the chassis and the support aid is adapted to adjust the inclination of the chassis while maintaining the already set support forces at the end of the Abstützvorganges.
  • the AbstNeill generate during the Abstützvorganges, while adjusting the support forces to minimize the inclination of the chassis, ie level the chassis.
  • the support legs are first extended by an operator to the ground before the support aid adjusts the determined support forces by the automatic extension of the support legs.
  • this measure provides a defined starting point for the automatic support and the operator can ensure that the support feet are lowered correctly on a sufficiently firm surface before the large manipulator is supported.
  • the program-controlled support aid is set up to display the ascertained support forces on a display device.
  • the operator of the large manipulator even before the extension of the support legs recognize how the support forces should each distribute to the individual supports and ensure that the surface is sufficient for the respective support force to ensure the stability of the large manipulator during operation.
  • the support legs are extended manually controlled and measured by the support force sensors supporting forces are adjusted by the manual vertical retraction or extension of the support legs so that the adjusted support forces correspond to the support forces determined by the support.

  • the method according to the invention also comprises an automatic extension operation of the support legs, a continuous measurement of the support forces, a comparison of the currently measured support forces with the support forces to be set and readjustment of the support legs until the measured support forces match the determined support forces.

Abstract

L'invention concerne un manipulateur de grande taille mobile (10), en particulier une pompe automotrice, comportant un châssis (12), un bras de travail (13) dépliable et/ou déployable agencé sur le châssis (12) de manière à pouvoir tourner autour d'un axe vertical, des bras d'appui (14, 15, 16, 17) qui sont chacun agencés sur le châssis (12) et peuvent être déplacés horizontalement en totalité ou en partie d'une position de déplacement à une position d'appui, des jambes d'appui (18, 19, 20, 21) déployables verticalement agencées aux extrémités extérieures des bras d'appui (14, 15, 16, 17) et servant d'appui au manipulateur de grande taille mobile (10) en créant respectivement une force d'appui des jambes d'appui (18, 19, 20, 21). Le manipulateur comporte une assistance à l'appui (µ C) à commande par programme qui est conçue pour déterminer des forces d'appui théoriques (Fe1, Fe2, Fe3, Fe4) pour chacune des jambes d'appui (18, 19, 20, 21) en prenant en compte la position d'appui des bras d'appui (14, 15, 16, 17), le châssis (12) du manipulateur de grande taille (10) n'étant pas contraint lorsqu'il est en appui. L'invention concerne par ailleurs un procédé d'assistance à commande par programme d'un processus d'appui d'un manipulateur de grande taille mobile (10).
