The embodiment of the invention provides a thrust type hydraulic length adjusting device, and relates to the technical field of hydraulic cylinders. A thrust type hydraulic length adjusting device comprises a back plate, a top frame is fixedly connected to the top of the back face of the back plate, and piston cylinders are fixedly connected to the two sides of the top frame; the front face of the back plate is fixedly connected with an outer barrel section, an inner cavity of the outer barrel section is slidably connected with an inner barrel section, the top of the inner barrel section is fixedly connected with an upper lifting lug, and the bottom of the outer barrel section is fixedly connected with a lower lifting lug. The rear side of the back plate is provided with an acting assembly used for supplying a pressurization air source and a supply assembly used for adjusting the length of the inner shell ring. The self-adaptive adjustment effect of the thrust length is achieved through the acting assembly and the supply assembly in a pneumatic and hydraulic combined mode, auxiliary supporting treatment is carried out between the lower lifting lug and the cargo connecting piece through the adjusting assembly and the supporting assembly, and rotation work of the cargo connecting piece on an inner connecting pin shaft and an outer connecting pin shaft of the lower lifting lug is not affected.
