.Изобретение относитс к грузоподъемным машинам, в частности к трубоукладчикам .The invention relates to lifting machines, in particular pipelayers.

Известен кран-трубоукладчик со стрелой, складывающейс относительно шарнира, установленного с внешней стороны по отношению к базовой машине . Верхн секци стрелы при складывании вращаетс вокруг шарнира и занимает положение снаружи от нижней, прилега к ее наружной поверхкости . Применение складывающейс стрелы позвол ет обходитьс без демонтировани ее при перевозке трубоукладчика.A laying crane is known with a boom folding relative to a hinge mounted externally with respect to the base machine. The upper boom section, when folded, rotates around the hinge and occupies a position outside the lower one, adjacent to its outer surface. The use of the folding arm allows it to be dispensed with without dismantling it when transporting the pipe layer.

Недостатком крана вл ютс увеличенные транспортные габариты трубоукладчика по ширине за счет выступающэй верхней секции .The disadvantage of the crane is the increased transport dimensions of the pipe layer in width due to the protruding upper section.

Известен также кран-трубоукладчик, содежащий базовую машину с контргрузом и крановыми механизмами, на которой смонтирова ны продольные балки нижней секции стрелы, шарнирно соединенные с продольными балками верхней секции Also known is a pipe-laying crane, containing a base machine with counter-load and crane mechanisms, on which are mounted longitudinal beams of the lower boom section, pivotally connected with longitudinal beams of the upper section.

Такое решение вл етс наиболее близким к изобретению по технической сущности.Such a solution is closest to the invention in its technical nature.

Однако верхн секци такого крана укладываетс сверху кабины, увеличива транспортные габариты высоты базовой машины. В рабочем положении верхние секции стрелы присоедин ютс к нижним при помощи болтов, что увеличивает трудоемкость монтажно-демонтажных работ при переводе крана в транспортное положение и обратно.However, the upper section of such a crane is placed on top of the cabin, increasing the transport dimensions of the height of the base machine. In the working position, the upper sections of the boom are attached to the lower ones with the help of bolts, which increases the laboriousness of the assembly and dismantling operations when the crane is moved to the transport position and back.

Цель изобретени - уменьшение транспортных габаритов и трудоемкости монтажно-демонтажных работ.The purpose of the invention is to reduce the transport dimensions and the complexity of installation and dismantling.

Цель достигаетс тем, что оси продольных балок нижней секции стрелы смещены в плане в зоне шарнира относительно осей балок верхней секции, причем на продольных балках нижней секции смонтировано основание с проушинами, а на балках верхней секции -кронштейн скобы, взаимодействующие друг с другом при транспортировке крана-трубоукладчика .The goal is achieved by the fact that the axes of the longitudinal beams of the lower boom section are offset in the plan in the hinge zone relative to the axes of the beams of the upper section, and the longitudinal beams of the lower section have a base with eyelets, and on the beams of the upper section - a bracket that interacts with each other when transporting the crane - pipelayer.

Claims

The crane-paver makes the basic machine 1 with crane mechanisms. On the brackets fixed on the caterpillar car 2 of the base machine, by means of the hydraulic arm 3 on the axis 4, a folding arm with an arrow consisting of the upper 5 and lower G sections is installed. The lifting (lowering) of the load is carried out by a winch 7 and a rope-block system 8. The stability of the machine is ensured by the camera 9. The lower boom section is made of two longitudinal beams 10, on the surfaces of which, facing the tractor, there is a transverse beam I, rigidly connecting them basis. At the top of the beam 10 are rigidly connected by a transverse base 12 arranged in the same manner as the beam 11. On base 12, lugs 13 are made, to which a hydraulic cylinder 3 tilts the boom as well as lugs 15 is attached to the pallet 14. The beams 10 of the lower section 6 end with lugs 16. The boom section 5 is formed by longitudinal beams 17 that are rigidly connected to each other from above and terminated at the bottom with lugs 18. At the base of the upper section of the boom, the beams 17 are rigidly connected with a yoke 19 terminated with a bracket 20. Section 5 of the jib is connected with the lower lugs 18 entering between the lugs 16 and the fingers 21 connected to them, and is locked by turning with a finger 22, installed in the eyes 15 and the bracket 2O. The longitudinal beams of the upper and lower section 35 are made with steps 23 and 24, which act as stops when the boom sections rotate, one is relative to the other. The installation of the crane is carried out as follows.40. The crane-paver delivered to the platform is set to its original position, then a cargo cable is selected with a winch 7, with which the upper section 5 is turned, pivoting on the fingers 21. After the final position is reached, the section 5 is fixed with a finger 22, after the end layer is ready work. For trans | 1 sort of speck about 1 c and ii.i; worn down in reverse order. Take out the finger 22, then loosen the load hey kppat. Secchi 5 under the influence of the force of gravity descends and takes place inside section 6 between its beams (in Fig. 1 this position is shown in dotted lines). Zat.g section 5 is attached to the beam 11 and gi.arokilindrom 3 raise the folded boom to the extreme position. The crane is ready for transport. Such a construction of a crane-pipe-cube makes it possible to reduce the labor-consuming installation of the dismantling works and reduce the transport dimensions. At the same time, to transfer the pipelayer si, the transport position does not require additional lifting devices. Claims of a pipe-laying machine containing a base machine with counter-load and crane mechanisms on which longitudinal beams of the lower boom section are mounted, hingedly connected with longitudinal beams of the upper section, characterized in that, in order to reduce the transport dimensions and laboriousness of assembly and disassembly works, axes in the plan of the hinge relative to the axes of the beams of the upper section, with the base with eyelets mounted on the longitudinal beams of the lower section, and on the bulkhead The upper section ah - bracket bracket, interacting with each other, during transport of the crane.
