The invention provides an adjustable lifting device for rapidly grabbing and fishing a reinforcement cage in a mud hole. The adjustable lifting device comprises a lifting rod, supporting rods and guide rods; the upper end of the lifting rod is used for being connected with lifting equipment; two connecting plates are oppositely arranged on the side wall of the lower end of the lifting rod; the middle of the lifting rod is sleeved with a guide sliding sleeve; two guide lug plates are oppositely arranged on the outer side wall of the guide sliding sleeve; the connecting plates and the guide lug plates are located in the same vertical plane; the two supporting rods are arranged; the lower ends of the two supporting rods are hinged to the connecting plates correspondingly; the upper ends of the two supporting rods are hinged to the lower ends of the guide rods correspondingly; and the upper ends of the two guide rods are hinged to the guide lug plates correspondingly. By the adoption of the device, the reinforcement cage in the mud hole can be conveniently and rapidly grabbed and fished, meanwhile, the reinforcement cage is not damaged, the original mud hole is not damaged, and normal construction production can be rapidly recovered.
Description
Technical field [0001] The present invention relates to the field of steel cage salvage, and in particular, there is a lifting device for adjustable rapid fucking mud holes. Background technique [0002] In recent years, with the rapid development of socio-economic, infrastructure is also increasing, and the drilling and perfusion pile schievement is more common. During the construction of the drilling pile, the steel cage is also refined into the mud hole due to various reasons during installation. Due to the limited conditions, the operation is difficult, it takes a long time to get it. The usual approach is to make a hook constantly explore in the well, and it takes a long time to hook the steel cage. Even if the hook hangs the steel cage, because the steel cage is single-sided force, the cage is also severely deformed even by the forced drape, and cannot be used. At the same time, due to the inclusion of the steel cage, the destruction caused by the mud hole wall is also very...
