[0001] The utility model relates to the technical field of power-assisted mechanical arms, in particular to a lifting power-assisted mechanical arm device of special equipment. Background Art

[0002] Power-assisted manipulators are also called power-assisted manipulators or labor-saving manipulators. They are power-assisted devices used for labor-saving operations during material handling and assembly. Power-assisted manipulators apply the principle of force balance, allowing operators to push and pull the transported objects or operating handles with a relatively small force, so that objects can be balanced and moved in space. When heavy objects are lifted or lowered, they form a floating state, and the heavy objects can be placed in a specified position in the space. When pushing and pulling heavy objects or operating handles, the operator does not need to overcome the gravity of the heavy objects to do work, which is more labor-saving.

[0003] Compared with the prior art, there are problems: the existing power-assisted robotic arms have poor flexibility when used, and cannot be customized to the weight of the transported equipment. The lifting height of the equipment and the starting force of the lifting operation cannot be adjusted, resulting in poor flexibility in the lifting operation of the equipment, and lifting is laborious. It is inconvenient to use and control the power-assisted robotic arms, and the practicability of the device is poor.
