[0025] The embodiment of the present utility model provides an automatic lifting and transporting device for waste power batteries, including a conveyor belt 1 and a gantry 2. For example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the gantry 2 is located at one end of the conveyor belt 1, and a lifting platform 3 is installed inside the gantry 2.

A mounting plate 6 is provided at the bottom of the lifting platform 3, and both sides of the mounting plate 6 are fixedly connected to the sliding block 5. A driving motor 7 is installed on the top of the mounting plate 6, and a transmission wheel 8 is installed at one end of the driving motor 7. A transmission belt 9 used in conjunction with the rotating shaft is installed on the surface of the transmission wheel 8. A groove 20 used in conjunction with the transmission belt 9 is provided on one side of the lifting platform 3. An auxiliary wheel 10 is provided at the bottom of the lifting platform 3, and both sides of the auxiliary wheel 10 are rotating The lifting platform 3 is dynamically connected with a convex plate 21, the top of the convex plate 21 is fixedly connected to the bottom of the lifting platform 3, the auxiliary wheel 10 is used in conjunction with the transmission belt 9, the top of the lifting platform 3 is fixedly connected with a limit sensor 11, the number of the limit sensors 11 is two, and the limit sensor 11 is used in conjunction with the drive motor 7. Both sides of the sliding block 5 are fixedly connected with a slider 12, and the interior of the stroke groove 14 is provided with a slide groove 13 used in conjunction with the slider 12. A contact sensor 17 is installed on the top of the conveyor belt 1 near one end of the gantry 2, and a contact block 16 used in conjunction with the contact sensor 17 is installed on the top of the lifting platform 3, and the contact block 16 is L-shaped. The bottom of the gantry 2 is fixedly connected with a base plate 18, the number of the base plates 18 is two, and the base plate 18 is arranged in a rectangular structure. Both ends of the top of the base plate 18 are fixedly connected with a support column 19, and the other end of the support column 19 is fixedly connected to the gantry 2.

[0026] Working principle: When the power battery is transported to the surface of the belt 4 through the conveyor belt 1 and is detected by the limit sensor 11, the signal transmitted by the limit sensor 11 stops the drive motor 7 from running, and at the same time stops the conveyor belt 1 from conveying the power battery, and transmits a signal to the telescopic cylinder 15, so that the telescopic cylinder 15 drives the sliding block 5 to lift. When the lifting platform 3 is lifted to a suitable height through the cooperation of the sliding block 5 and the telescopic cylinder 15, the signal is transmitted to the drive motor 7 to make the drive motor 7 run, thereby driving the internal shaft of the lifting platform 3 to rotate through the transmission belt 9, so that the belt 4 drives the power battery to move, so that the power battery is moved to the subsequent program through the operation of the belt 4, and then stretched. The retracting cylinder 15 drives the sliding block 5 to lower the lifting platform 3. When the contact block 16 on the top of the lifting platform 3 contacts the contact sensor 17, the contact sensor 17 transmits a signal to the drive motor 7, the telescopic cylinder 15 and the conveyor belt 1, so that the telescopic cylinder 15 stops running, and at the same time the drive motor 7 and the conveyor belt 1 are operated to transport the power battery. When the front end of the power battery is detected by the limit sensor 11 again, the above-mentioned lifting process is repeated, and the sliding connection between the slider 12 and the slide groove 13 can ensure the stability of the sliding block 5 when it is lifted and lowered inside the travel groove 14. The setting of the bottom plate 18 and the support column 19 can better support the gantry 2 and effectively prevent the gantry 2 from tipping over.

[0027] When the power battery reaches the specified position, the limit sensor 11 detects its presence and a signal is sent to the control system, causing the conveyor belt 1 to stop and preventing new power batteries from entering the lifting area; the control system starts the telescopic cylinder 15 to lift the platform carrying the power battery to the required height. When the power battery reaches the correct position, the control system starts the drive motor 7 so that the power battery can be moved through the cooperation of the drive motor 7 and the belt 4. After the operation is completed, the control system restarts the conveyor belt 1 and prepares to receive the next power battery. No human participation is required throughout the process, which can effectively improve efficiency and avoid safety hazards caused by power battery explosions.

[0028] In order to ensure the safety and stability of the entire system during operation, the design includes multiple support points and detection points to prevent accidents during operation of the equipment. The sliding connection design not only ensures the smoothness of the lifting process, but also allows the lifting mechanism to move up and down within the fixed track, increasing the reliability of the system. The specific support structure base plate 18 and support column 19 are used to strengthen the stability of the entire frame to prevent the risk of tilting or collapse of the main frame gantry 2. When the sensor contact sensor 17 detects that the platform returns to the initial position, the equipment status can be adjusted in time to ensure that all components are in safe working conditions.
