The invention discloses a hoisting device for mechanical parts. The hoisting device comprises a machine body, a rope and a base, a movable pulley and a fixed pulley are installed on the machine body, the movable pulley and the fixed pulley are wound around the middle position of the rope, one end of the rope is connected to a hook of the movable pulley, the base is installed at the bottom end of the machine body, a fixing assembly is connected to the other end of the rope, clamping grooves are formed in the inner walls of the left end and the right end of the machine body correspondingly, wheels are connected to the bottom end of the base through springs, and switches are arranged at the left end and the right end of the base correspondingly. Threaded rods are rotated by rotating the switches, the threaded rods are separated from threaded grooves under the action of threads, at the moment, sliding blocks are not limited any more, then the wheels are stored in the machine body under the gravity of the machine body, the stability of the hoisting device during use is guaranteed, and the wheels are ejected out under the elastic action of the springs when the hoisting device needs to be used, the practicability of the device is improved, and the labor cost of manual carrying is reduced.

本发明公开了一种机械配件的吊装装置，包括机身、绳索和底座，所述机身上安装有动滑轮和定滑轮，所述绳索中间位置缠绕有动滑轮和定滑轮，所述绳索的一端连接有动滑轮的挂钩上，且机身底端安装有底座，所述绳索的另一端连接有固定组件，所述机身左右两端内壁上皆开设有卡槽，且底座底端通过弹簧连接有轮子，所述底座左右两端皆设置有开关。本发明通过转动开关使螺纹杆转动，在螺纹的作用下使螺纹杆脱离螺纹槽，此时滑动块不再受到限位，随后在机身自身的重力下使轮子收纳到机身内部，保证使用时装置的稳定性，当需要使用时在弹簧的弹性作用下将轮子弹出即可，提升了装置的实用性，减少了人工搬运的劳动成本。
