The invention relates to the technical field of underground hydraulic hoisting, in particular to a variable underground hydraulic hoisting device. The invention provides a variable underground hydraulic hoisting device which can enable an underground instrument to be more stable in hoisting, transporting and advancing and improve the hoisting safety and stability. A variable underground hydraulic lifting device comprises walking bases, hydraulic pumps, hydraulic supporting legs, a cross beam and the like, the two walking bases are arranged in a bilateral symmetry mode, the hydraulic pumps are connected to the sides, away from each other, of the rear portions of the walking bases, the hydraulic supporting legs are connected to the upper sides of the front portions and the rear portions of the walking bases, and the cross beam is connected between the tops of the hydraulic supporting legs. The first hydraulic cylinder upwards jacks the first rotating plate to drive the supporting plate to move upwards to make contact with the bottom of the underground instrument, stable supporting operation is conducted on the bottom of the underground instrument, the underground instrument can be more stable during hoisting and transportation, and hoisting safety and stability are improved.
本发明涉及井下液压起吊技术领域,尤其涉及一种可变式井下液压起吊装置。本发明提供一种能够使得井下器械在起吊运输行进更为稳定,增加起吊安全性和稳定性的可变式井下液压起吊装置。一种可变式井下液压起吊装置,包括有行走底座、液压泵、液压支脚和横梁等,行走底座共有两个且呈左右对称设置,行走底座后部相互远离的一侧上均连接有液压泵,行走底座前后两部上侧均连接有液压支脚,液压支脚顶部之间连接有横梁。本发明通过第一液压缸向上顶升第一转动板带动托载板向上移动,与井下器械底部接触,对井下器械底部进行托载稳定的操作,能够使得井下器械在起吊运输行进更为稳定,增加起吊安全性和稳定性。
