The invention discloses a counterweight battery installation auxiliary arm which comprises a moving mechanism, a main mechanical arm, a rotary joint, a mechanical arm, an operating
handle, a lifting hook, a suction cup, an air source pipeline and a safety protection valve, the main mechanical arm is arranged on the moving mechanism in a multidirectional adjustment mode, and the mechanical arm is rotatably arranged on the main mechanical arm through the rotary joint; the operating
handle is arranged on the
manipulator, the lifting hook is arranged at the front end of the bottom of the
manipulator and used for lifting a battery, the suction cup is arranged at the bottom of the
manipulator and used for adsorbing a balancing weight, the air source pipeline is connected with the suction cup and used for providing
suction force for the suction cup, and the safety protection valve is arranged on the air source pipeline and used for preventing the balancing weight adsorbed on the suction cup from falling off after air is
cut off. The overall structure is simple, multidirectional movement can be achieved, it is effectively ensured that the balance weight and the battery can be accurately moved to the designated installation position, manpower is effectively reduced, the assembling efficiency is improved, the
falling risk of the balance weight in the moving process is effectively avoided, and the
transportation safety is improved.
