Abstract

A multi-section telescopic boom device is disclosed, which comprises a rope lay connecting part and a pin connecting part. The rope lay connecting part comprises at least two section telescopic booms which are located in the inner side and connected by turning wheels and cables. The pin connecting part comprises at least one section telescopic booms and a basic boom (211) both located in the outer side and connected by boom pins and cylinder pins. A cylinder barrel (281) of a telescopic oil cylinder (28) is connected with the outermost section of the telescopic booms of the rope lay connecting part. Therefore, in the extending/retracting process of the telescopic booms, each section of telescopic booms of the rope lay connecting part extends/retracts synchronously, thus increasing the extending/retracting speed of the telescopic boom device to improve the working efficiency. At the same time, the rope lay connecting part is connected with the pin connecting part by boom pins, so that the axial force between the telescopic booms is transferred by the boom pin to improve the stress condition of the telescopic oil cylinder, thus reducing suitably the design dimension of telescopic oil cylinder to reduce the cost. An automobile crane with the above-mentioned multi-section telescopic boom device is also disclosed.
