[0022] The connecting seat 6 is internally movably hinged with two hydraulic rods 7, and the telescopic end of each hydraulic rod 7 is movably hinged with a connecting plate 8. The back of each connecting plate 8 is fixedly connected to the outer surface of the rotating sleeve 3. The fixed frame 1 is internally rotatably connected with a bidirectional screw 9, and the left end of the bidirectional screw 9 is fixedly connected to a rotating disk 19, and the left side of the rotating disk 19 is fixedly connected to a handle 20. Manually holding the handle 20 and rotating the rotating disk 19 can drive the bidirectional screw 9 to rotate, thereby increasing the convenience of manual operation of the bidirectional screw 9.

[0023] The outer surface of the bidirectional screw 9 is threadedly connected to two sliding seats 10, each sliding seat 10 is slidably connected to the inside of the fixing frame 1, and the inside of the fixing frame 1 is fixedly inlaid with two auxiliary bearings 21. The inner wall of the inner ring of each auxiliary bearing 21 is fixedly connected to the outer surface of the bidirectional screw 9. The auxiliary bearings 21 can assist the bidirectional screw 9 to rotate, reduce the friction between the bidirectional screw 9 and the fixing frame 1, and increase the service life of the bidirectional screw 9.

[0024] The upper surface and bottom surface of each sliding seat 10 are fixedly connected with a telescopic cylinder 11, and the interior of each telescopic cylinder 11 is slidably connected with a telescopic plate 12. The outer surface of the bidirectional screw 9 is rotatably connected with a bearing seat 22, and the outer surface of the bearing seat 22 is fixedly connected to the inner wall of the fixed frame 1. The bearing seat 22 can increase the stability of the bidirectional screw 9, so that the bidirectional screw 9 is not prone to excessive swinging when rotating, thereby ensuring the stable operation of the bidirectional screw 9.

[0025] The front side of each telescopic plate 12 is provided with adjustment holes 13 arranged at equal distances, the outer surface of each sliding rod 2 is slidably connected to two sliding sleeves 14, the side of each group of sliding sleeves 14 close to each other is fixedly connected to the side of each group of telescopic plates 12 away from each other, and the interior of each telescopic cylinder 11 is clamped with a locating pin 23, and the end of each locating pin 23 close to the telescopic cylinder 11 passes through the telescopic cylinder 11 and one of the adjustment holes 13 in sequence and extends to the back side of the telescopic cylinder 11.

[0027] The working principle of the utility model is as follows: when in use, the hydraulic rod 7 is first connected to the power supply, and then the lifting steel cable is connected to the device through the lifting ring 25 and the fixed plate 24. When it is necessary to clamp and lift the lower box of the liquid-cooled energy storage PACK of different specifications, the power provided by the hydraulic rod 7 is used in conjunction with the movable hinge relationship with the connecting seat 6 to drive the connecting plate 8 movably hinged to the telescopic end of the hydraulic rod 7 for adjustment, and then the rotating sleeve 3 can be driven to rotate on the sliding rod 2, so that the two clamping rubber rods 5 can be driven to approach each other in conjunction with the connecting frame 4, so that the position of the lower box of the liquid-cooled energy storage PACK can be clamped and fixed from the upper and lower directions, and the clamping distance in the upper and lower directions can be fine-tuned by adjusting the extension amount of the hydraulic rod 7, thereby preliminarily increasing the clamping adaptability of the lower box clamp of the liquid-cooled energy storage PACK, and then the telescopic plate 12 is used to extend and retract inside the telescopic cylinder 11 and cooperate with the positioning of the adjusting hole 13 and the positioning pin 23 to adapt to the adjustment of the extension amount of the hydraulic rod 7, and then the bidirectional screw is manually rotated using the handle 20 and the rotating disk 19. 9 cooperates with the fixing frame 1, utilizes the characteristics of the bidirectional screw 9 and the threaded connection relationship between the bidirectional screw 9 and the sliding seat 10, can drive the sliding seat 10 to slide left and right inside the fixing frame 1, and because the rotating sleeve 3 can only rotate on the sliding rod 2, and cannot slide on the sliding rod 2, it can drive the telescopic cylinder 11 and the telescopic plate 12 to adjust to each other or move away from each other, and then can drive the two sets of sliding sleeves 14 to slide on the sliding rod 2 to move closer to or away from each other. At this time, with the adjustment and positioning of the adjustment plate 15 and the positioning through hole 16 and the positioning column 17, the positioning column 17 can be quickly inserted from both sides into the reserved hole inside the lower box to complete the lifting and fixing, and the liquid-cooled energy storage PACK lower box lifting device can quickly adapt to liquid-cooled energy storage PACK lower boxes of different widths, so that the liquid-cooled energy storage PACK lower box lifting device can quickly adapt to the clamping and lifting work of liquid-cooled energy storage PACK lower boxes of different specifications, effectively increasing the compatibility and use effect of the liquid-cooled energy storage PACK lower box lifting device.
