Detailed implementation manners

[0029] The following will introduce the present utility model in detail with reference to the drawings:

[0030] Embodiment: As shown in the attached Figures 1 - 9 figures, this mobile battery installation trolley includes a frame 1, a hydraulic device 2, a rolling bearing 3, a limit stop 4, a wheel 5, a tray 6, an enclosure 7, a telescopic bracket 8, a handrail 9, a hydraulic trigger 10, a bearing bracket 11, a pin shaft 12, a stop block body 13, a screw 14, an adjusting nut 15, a welding point 16 and a power battery assembly 17.

[0031] Referring to the attached Figure 1 , 2 , wheels 5 are correspondingly arranged at the four corners of the bottom of the frame 1, and a handrail 9 is arranged on one side of the frame 1. The hydraulic device 2 is arranged on one side of the frame 1 close to the handrail 9, and the hydraulic device 2 is controlled by a hydraulic trigger 10. As shown in Figure 1 , 3 , the hydraulic trigger 10 is fixedly installed on the handrail 9. When the hydraulic trigger 10 is pressed, the hydraulic device 2 drives the telescopic bracket 8 on the frame 1 to move up and down, and synchronously drives the tray 6 placed on the top of the telescopic bracket 8 to move up and down.

[0032] As shown in Figure 1 , 4 , three groups of bearing brackets 11 (three groups in this embodiment, and it can also be other quantities) are arranged at intervals on the tray 6, and seven rolling bearings 3 (seven in this embodiment, and it can also be other quantities) are rotatably connected in each group of bearing brackets 11, so that the power battery assembly 17 is placed on the rolling bearings 3 in the transverse or longitudinal direction. The rolling bearings 3 play a role in reducing the friction at the bottom of the power battery assembly 17 and reducing the pushing friction of the battery box. Preferably, the rolling bearings 3 are installed on the bearing brackets 11 through pin shafts 12. The two sides of the tray 6 are bent upwards by 90° to form an enclosure 7, which can prevent the power battery assembly 17 from falling during installation and solve the efficiency and safety problems during installation. The tray 6 is made of Q235 steel plate with a plate thickness of 1.0 mm, the thickness of the electrophoretic paint on the outer surface is 30 μm, and the thickness of the surface paint is 50 μm.

[0033] Furthermore, referring to the attached Figure 1 , 4, 5. A limit stop 4 is provided on the tray 6 between each group of bearing brackets 11. The limit stop 4 includes a stop body 13 and a screw 14. The two ends of the screw 14 are welded and fixed on the surface of the tray 6 through welding points 16. Corresponding holes are provided on the stop body 13 for the screw 14 to pass through, so that the stop body 13 can rotate relative to the screw 14. At the same time, adjusting nuts 15 are provided on both sides of the stop body 13, and the adjusting nuts 15 can lock the rotation angle of the stop body 13. Preferably, as Figure 5 shown, the width of the stop body 13 is less than or equal to the height of the bearing bracket 11, so that when the stop body 13 is placed horizontally, its height is flush with or lower than that of the bearing bracket 11, and it will not hinder the installation of the power battery assembly 17; at the same time, the length of the stop body 13 is greater than the height of the bearing bracket 11, so that after the stop body 13 rotates, its height is higher than that of the bearing bracket 11, forming a block for the power battery assembly 17 to prevent the power battery assembly 17 from slipping off.

[0034] The working process of the present utility model: The power battery assembly 17 is hoisted onto the rolling bearing 3 of the mobile battery installation trolley. The limit stop 4 (stop body 13) rotates upward and is higher than the bearing bracket 11 to prevent the power battery assembly 17 from sliding. The trolley is moved to the vehicle installation position, and the left and right positions are adjusted by moving the wheels 5. The height is adjusted to the appropriate installation position through the hydraulic device 2. The limit stop 4 is opened (that is, the stop body 13 is rotated so that the stop body 13 is flush with the bearing bracket 11), and the power battery assembly 17 is slid into the battery box by using the rolling bearing 3. The height of the trolley is lowered, the trolley is removed, and it is fastened with bolts; the same also applies to the disassembly, installation and maintenance of the power battery assembly.

[0035] As Figure 6 , 7 shown, the power battery assembly 17 is placed horizontally (that is, the length direction of the power battery assembly 17 is parallel to the axial direction of the rolling bearing 3), spanning three bearing brackets 11; as Figure 8 , 9 shown, the power battery assembly 17 is placed longitudinally (that is, the length direction of the power battery assembly 17 is perpendicular to the axial direction of the rolling bearing 3), and the power battery assembly 17 is supported on the middle bearing bracket 11, with stronger versatility.

[0036] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and the inventive concept of the present utility model should fall within the protection scope of the appended claims of the present utility model.
