The battery swapping equipment is then used to replace the batteries of electric vehicles at the battery distribution stations.

[0003] Battery swap equipment mainly includes a lifting mechanism and a battery swap hoist. After the battery swap hoist grabs the battery, it is driven by the lifting mechanism to move the battery swap hoist into or out of the electric vehicle. However, existing battery swap hoists can only grab batteries of a single size and cannot meet the battery swap needs of multiple sizes.

[0004] In order to overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN202222140419.X, application date 2022-08-15) is a battery swap hanger and battery swap equipment, which can adjust the distance between the two hooks so that batteries of different sizes can be inserted between the two hooks, and then the two hooks are closed to complete the grabbing of batteries of different sizes;

[0005] The above-mentioned equipment cannot fix the spreader when it grabs the battery, causing the spreader to shake during operation, affecting the battery and reducing the battery life;

[0006] In response to the above problems, it is urgently necessary to carry out innovative design based on the original battery replacement hoist and battery replacement equipment. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0035] Example 1: By setting the connection between the support frame 4, the base 15 and the sling 19, the stability of the crane hoist is improved, such as Figure 1-Figure 2 As shown:

[0036] The support frame 4 comprises a support frame 4 and a base 15. The motor 1 is fixedly connected to the surface of the support frame 4, the fixed block 3 is fixedly connected to the surface of the support frame 4, and the inner side of the support frame 4 is fixedly connected to the limit column 11. At the same time, the inner side of the support frame 4 is movably connected to the second rotating shaft 10, and the inner side of the support frame 4 is movably connected to the third rotating shaft 23.

[0037] The upper surface of the base 15 is fixedly connected to the tightening wheel 14, and the base 15 is provided with a movable groove 16 inside. The surface of the movable groove 16 is slidably connected to the second movable block 17, and the lower surface of the second movable block 17 is movably connected to the sling 19.

[0038] Also includes:

[0039] The output end of the motor 1 is fixedly connected to the No. 1 rotating shaft 2, and the right side of the No. 1 rotating shaft 2 is connected to the inside of the fixed block 3. The surface of the No. 1 rotating shaft 2 is movably connected to the cable 13, and the other end of the cable 13 is movably connected to the inside of the tightening wheel 14. The upper surface of the base 15 is provided with a locking component to prevent movement. The upper surface of the support frame 4 is slidably provided with the No. 1 moving block 8, and the surface of the No. 1 moving block 8 is provided with a winding component for even winding.

[0040] When the motor 1 is working, it drives the No. 1 rotating shaft 2 to rotate, and at the same time, the cable 13 is wound on the surface of the No. 1 rotating shaft 2. The cable 13 passes through the inside of the tightening wheel 14, drives the base 15 to move upward, and the sling 19 drives the battery to move. In addition, the setting of the limit column 11 on the inner side of the support frame 4 limits the movement range of the cable 13, prevents the cable 13 from deviating from the normal track during operation, avoids safety accidents caused by the loss of control of the cable 13, and improves the stability of the device.

[0041] Embodiment 2. In this embodiment, different from the embodiment 1, the connection between the third rotating shaft 23, the pulley 5 and the cam 7 is set so that the first moving block 8 slides on the surface of the support frame 4, as shown in FIG. Figure 3-Figure 4 As shown:

[0042] The winding assembly includes a pulley 5 which is sleeved and connected to the surface of the No. 1 rotating shaft 2, and the other end of the pulley 5 is sleeved and connected to the No. 2 rotating shaft 10, the No. 3 rotating shaft 23 is rotatably arranged inside the support frame 4, and the surface of the No. 3 rotating shaft 23 is fixedly connected to the cam 7, and the upper surface of the No. 3 rotating shaft 23 and the end of the No. 2 rotating shaft 10 are fixedly connected to the bevel gear 6, the surface of the limiting column 11 is movably connected to the No. 1 moving block 8, and the left side of the No. 1 moving block 8 is fixedly connected to the spring 9, and the other end of the spring 9 is fixedly connected to the support frame 4, the rear side of the No. 1 moving block 8 is fixedly connected to the swing column 12, and the cable 13 runs through the interior of the swing column 12.

[0043] When the No. 1 rotating shaft 2 rotates, it drives the pulley 5 to rotate the bevel gear 6 at the end of the No. 2 rotating shaft 10, and a cam 7 is installed on the surface of the No. 3 rotating shaft 23. As the No. 3 rotating shaft 23 rotates, the cam 7 causes the No. 1 moving block 8 to slide on the surface of the support frame 4. Due to the action of the spring 9, when the cam 7 moves away from the No. 1 moving block 8, the spring 9 resets the No. 1 moving block 8. At the same time, as the No. 1 moving block 8 moves, the swing column 12 drives the cable 13 to swing or adjust its position to a certain extent, avoiding local accumulation or excessive tension of the cable 13, thereby achieving the function of uniform winding.

[0044] Embodiment 3. In this embodiment, the difference from embodiment 2 is that the second moving block 17, the rotating groove 20 and the rotating column 21 are connected so that the rotating rod 22 is engaged in the connecting groove 18. Figure 5-Figure 6 As shown:

[0045] The locking assembly includes a connecting groove 18 fixedly connected to the inside of the base 15, and the connecting grooves 18 are evenly spaced on the upper surface of the base 15. A rotating groove 20 is opened inside the No. 2 moving block 17, and a rotating column 21 is fixedly connected to the surface of the rotating groove 20, and the surface of the rotating column 21 is movably connected to the rotating rod 22.

[0046] The rotating groove 20 inside the No. 2 moving block 17 provides an installation space for the rotating column 21. The rotating column 21 is fixed on the surface of the rotating groove 20, so that the rotating column 21 can maintain a relatively stable position in the rotating groove 20. At the same time, the rotating rod 22 is movably connected to the surface of the rotating column 21. The rotating rod 22 can rotate around the rotating column 21, and the rotating rod 22 is engaged with the connecting groove 18, which improves the stability of the crane hoist and reduces the maintenance and adjustment costs caused by equipment instability, ensuring the smooth progress of the lifting work.

[0047] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
