The invention discloses a single-cantilever gantry crane, belongs to the technical field of cranes, and aims to solve the problems of high manpower consumption and low working efficiency during volute hoisting. The single-cantilever gantry crane comprises a crane body, a hoisting mechanism is slidably connected to the lower part of a horizontal section of the crane body, a rope is connected to the interior of the hoisting mechanism, and a lifting hook is fixed to the bottom end of the rope; the sleeve shell is arranged below the lifting hook, and four side openings distributed circumferentially are formed in the outer side wall of the sleeve shell; the four supporting rods make contact with the inner wall of the top face opening of the volute, when the sleeve barrel moves downwards, a first limiting stopper can move upwards through cooperation of a first rack, a second rack and a gear, then the four supporting rods can be folded, the sleeve shell is conveniently placed in the volute, and the sleeve barrel is moved upwards, so that the sleeve barrel is convenient to use. And the four supporting rods can be unfolded outwards to stably fix the volute, so that a large amount of manpower consumption can be saved, the working efficiency and the stability of volute positioning are improved, and the situation that the volute shakes when moving is avoided.
本发明公开了一种单悬臂龙门起重机,属于起重机技术领域,针对了起重蜗壳时人力消耗大,工作效率低的问题,包括起重机本体,起重机本体水平段下部滑动连接有起吊机构,起吊机构内部连接有绳索,绳索底端固定有吊钩;套壳,设置于吊钩下方,套壳外侧壁开设有四个呈圆周分布的侧口;本发明使得四个支撑杆与蜗壳顶面口内壁接触,套桶下移时,能够通过第一齿条、第二齿条和齿轮之间的配合,使得第一限位器上移,进而使得四个支撑杆能够收拢,方便将套壳放置于蜗壳内部,通过上移套桶,使得四个支撑杆能够向外撑开将蜗壳稳定固定住,从而能够节省大量人力消耗,提高了工作效率和蜗壳定位的稳定性,避免了蜗壳移动时发生晃动的情况。
