The invention provides a multipurpose crane based on an air cylinder type telescopic crane jib. The multipurpose crane comprises a base, a stand column, a telescopic adjusting supporting leg and a crane jib, the lower end of the stand column and the lower end of the adjusting supporting leg are fixed to the base, one end of the crane jib is hinged to the upper end of the stand column, the middle of the crane jib is hinged to the upper end of the adjusting supporting leg, and the crane jib comprises three telescopic air cylinders and three telescopic beams. The three telescopic cylinders are respectively a first transverse cylinder, a second transverse cylinder and a third transverse cylinder, the three telescopic cylinders are sequentially inserted end to end, an air delivery pipe is further arranged on the crane jib and sequentially connected with the three telescopic cylinders in series, the three telescopic beams are respectively a first telescopic beam, a second telescopic beam and a third telescopic beam which are sequentially inserted, the first transverse cylinder is fixedly connected with the first telescopic beam, and the second transverse cylinder is fixedly connected with the second telescopic beam. The third transverse cylinder is fixedly connected with the third telescopic beam. The multipurpose crane has the beneficial effects that the telescopic length of the crane jib is greatly prolonged, and each telescopic cylinder adopts a pneumatic mode, so that the multipurpose crane is simple to process and convenient to control and maintain in the later period.

    本发明提供一种基于气缸式伸缩吊臂的多用起重机,包括底座、立柱、伸缩式调节支腿和吊臂,立柱下端和调节支腿下端固定于底座上,吊臂一端铰接于立柱上端,中部铰接于调节支腿上端,吊臂包括三个伸缩气缸和三个伸缩梁,三个伸缩气缸分别为第一、二、三横向气缸,三伸缩气缸收尾依次插接,吊臂上还设有输气管,输气管依次串联三伸缩气缸,三个伸缩梁分别为依次插接的第一、二、三伸缩梁,第一横向气缸固定连接第一伸缩梁,第二横向气缸固定连接第二伸缩梁,第三横向气缸固定连接第三伸缩梁。本发明的有益效果:大大延长了吊臂伸缩长度,且采用每一伸缩气缸采用气动这种方式,加工简单,便于控制,及后期维护。
