The invention discloses a portable embedded direct-current electric hoist. The portable embedded direct-current electric hoist comprises a permanent magnet brushless direct-current motor, a controller, a left end plate, a right end plate, a rope roll, a first speed reduction device and a second differential transmission device, wherein the rope roll is rotationally arranged on the left end plate and the right end plate; a built-in motor base fixed to the right end plate is arranged in the rope roll; the permanent magnet brushless direct-current motor and the first speed reduction device are fixed to the built-in motor base in a butt joint manner, and the permanent magnet brushless direct-current motor and the first speed reduction device are embedded in the rope roll; the second differential transmission device is fixed to the left end plate and connected with the first speed reduction device through a transmission shaft; and during work, the permanent magnet brushless direct-current motor drives the second differential transmission device to rotate through the first speed reduction device and the transmission shaft, and the second differential transmission device drives the rope roll to rotate and work. After the above structure is adopted, the beneficial effects that the structure is simple and reasonable, hoisting is flexible and light, the size is small, the transmission efficiency is high, the braking effect is good, and usage is safe and reliable are achieved.

    本发明创造公开了一种便携内嵌式直流电动葫芦,包括永磁无刷直流电机、控制器、左右端板、绳筒、第一减速装置、第二差速传动装置,绳筒可转动地设置在左右端板上,所述的绳筒内设有与右端板固定的内置电机座,永磁无刷直流电机和第一减速装置对接固定在内置电机座上,使永磁无刷直流电机和第一减速装置内嵌在绳筒内,第二差速传动装置固定在左端板上并通过传动轴与第一减速装置连接;工作时永磁无刷直流电机通过第一减速装置、传动轴带动第二差速传动装置转动,第二差速传动装置带动绳筒旋转工作。采用上述结构后,具有结构简单合理、吊装灵活轻便、体积小、传动效率高、制动效果好、使用安全可靠等优点。
