[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 2 As shown, the counterweight battery installation auxiliary arm of the present invention includes a mobile mechanism 1, a main mechanical arm 2, a rotary joint 3, a manipulator 4, an operating handle 5, a hook 6, a suction cup 7, an air source pipeline 8 and a safety protection valve 9. The main mechanical arm 2 can be adjusted in multiple directions and is arranged on the mobile mechanism 1. The manipulator 4 is rotatably arranged on the main mechanical arm 2 through the rotary joint 3. The operating handle 5 is arranged on the manipulator 4. The hook 6 is arranged at the bottom front end of the manipulator 4 for lifting the battery. The suction cup 7 is arranged at the bottom of the manipulator 4 for adsorbing the counterweight block. The air source pipeline 8 is connected to the suction cup 7 for providing suction to the suction cup 7. The safety protection valve 9 is arranged on the air source pipeline 8 to prevent the counterweight adsorbed on the suction cup 7 from falling after the air is cut off.

[0029] The moving mechanism 1 includes two longitudinal mechanisms 12 and a transverse mechanism 13 . The two longitudinal mechanisms 12 are symmetrically arranged, and the transverse mechanism 13 is movably arranged between the two longitudinal mechanisms 12 .

[0030] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, a first track 121 is provided on the longitudinal mechanism 12, and lifting wheels 131 are provided at both ends of the transverse mechanism 13. The lifting wheels 131 are matched with the first track 121. The lifting wheels 131 are provided in the first track 121 and roll along the first track 121, thereby effectively moving the main robotic arm 2 forward and backward.

[0031] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, a second track 132 is provided on the transverse mechanism 13, and covered wheels 21 are symmetrically provided on both sides of the upper end of the main robotic arm 2. The covered wheels 21 match the second track 132. The covered wheels 21 are provided in the second track 132 and roll along the second track 132, thereby effectively enabling the main robotic arm 2 to move left and right.

[0032] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, the main robotic arm 2 can use an electric cylinder, an oil cylinder or a pneumatic cylinder, so that the counterweight and battery can be driven to move up and down when installing them, so that they reach the installation position height.

[0033] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, the output end of the main robotic arm 2 is fixedly connected to one end of the rotary joint 3.

[0034] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, the manipulator 4 is L-shaped, and the upper end of the manipulator 4 is fixedly connected to the other end of the rotary joint 3, thereby effectively ensuring that the manipulator 4 can rotate 360 degrees, and can install batteries and counterweights at different angles. A groove 41 is provided at the front end of the bottom of the manipulator 4, and the hook 6 is fixed in the groove 41, so that the hook 6 is hidden in the groove 41. When the counterweight is adsorbed and moved, it does not interfere with the hook 6, and there is no need to remove the hook 6, which effectively improves the efficiency of the conversion between the counterweight and the battery.

[0035] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, there are no less than four suction cups 7, and the suction cups 7 surround the bottom of the manipulator 4. The center point of the suction cups 7 corresponds to the counterweight installation hole, which effectively ensures the stability of the counterweight after adsorption and improves safety.

[0036] Furthermore, in the counterweight and battery installation auxiliary arm of the present invention, an operating button is provided on the operating handle 5, and the output end of the operating handle 5 is electrically connected to the mobile mechanism 1, the main robotic arm 2, the rotary joint 3 and the air source pipeline 8 respectively, so that the mobile mechanism 1 is controlled to move forward, backward, left and right through the operating handle 5, the main robotic arm 2 is controlled to extend and retract, the rotary joint 3 is controlled to rotate, and the air source pipeline 8 is controlled to open to allow compressed air to enter so that the suction cup 7 generates suction.

[0037] Specifically, when installing the counterweight, control the operating handle 5 to allow compressed air to enter the air source pipe 8 to generate suction on the suction cup 7. At this time, the operating handle 5 is used to control the lifting wheel 131 to move along the first track 121 and the covering wheel 21 to move along the second track 132, so that the suction cup 7 corresponds to the counterweight. At this time, the operating handle 5 is used to control the main robot arm 2 to extend and drive the robot arm 4 to descend, so that the suction cup 7 is completely fitted with the counterweight. At this time, it should be confirmed that the suction cup 7 surrounds the mounting hole on the counterweight so that the suction cup 7 avoids the mounting hole. Yes, at this time, the suction cup 7 and the counterweight are completely adsorbed, the main robot arm 2 is controlled to rise to the installation height, the counterweight is moved to the specified installation position by the moving mechanism 1, and the slewing joint 3 is adjusted to adjust the installation angle of the counterweight, and the main robot arm 2 is operated to descend. At this time, the air supply of the air source pipeline 8 is cut off to separate the suction cup 7 from the counterweight, and the installation is completed. If the air supply pipeline 8 is accidentally cut off during the installation of the counterweight, the safety protection valve 9 is immediately activated, so that the air supply pipeline 8 to the suction cup 7 is in a vacuum state, which effectively prevents the counterweight from falling;

[0038] When installing the battery, the operating handle 5 controls the lifting wheel 131 to move along the first track 121 and the covering wheel 21 to move along the second track 132, so that the hook 6 is above the battery to be installed. At this time, the operating handle 5 controls the main robotic arm 2 to extend and drive the manipulator 4 to descend, and the hook 6 is connected to the battery sling to control the main robotic arm 2 to rise to the installation height. The battery is moved to the designated installation position through the moving mechanism 1, and the rotary joint 3 is adjusted to adjust the battery installation angle. The main robotic arm 2 is operated to descend, and the sling is removed after the battery is installed.

[0039] To sum up, compared with the existing technology, the counterweight and battery installation auxiliary arm of the present invention has the following advantages and beneficial effects: the overall structure of the present invention is simple, and multi-directional movement is achieved through the cooperation of the moving mechanism and the rotary joint, which effectively ensures that the counterweight and battery can be accurately moved to the designated installation position, effectively reduces manpower, and improves assembly efficiency. The setting of the safety protection valve effectively avoids the risk of the counterweight falling during movement, thereby improving transportation safety.
