[0022] Specifically, the ice cubes are placed on the upper end of the support plate 21, and the servo motor 27 is started to drive the bidirectional threaded screw 26 to rotate, cooperate with the limit block 28 and the limit rod 29, and then drive the front and rear limit plates 23 to approach each other through the driving block 25, so as to clamp the lower end of the ice cube. At the same time, the anti-slip bumps 24 are evenly distributed on one side to prevent the ice cubes from sliding on the upper end of the support plate 21 during the loading and unloading process. By arranging the limit mechanism 2 at the upper end of the lifting bracket 3, the ice cubes will not easily slide on the upper end of the limit mechanism 2 during the loading and unloading process of the ice cubes, thereby avoiding the situation where the ice cubes slide and are damaged, and at the same time reducing the probability of safety accidents caused by the loading and unloading process of the ice cubes.

[0023] In this embodiment, the lifting mechanism 1 includes a base 11, the upper end of the base 11 is fixedly connected to the gantry 12, the front and rear sides of the middle of the upper end of the base 11 are fixedly connected to the limited sliding rod 13, the front upper end of the gantry 12 is fixedly connected to the reduction motor 14, the rear end driving end of the reduction motor 14 is fixedly connected to the drive shaft 15, the outer periphery of the drive shaft 15 is evenly distributed with sprockets 16, the outer periphery of the sprockets 16 are meshed with drive chains 17, and one end of the drive chain 17 is fixed.

[0026] First, place the ice cube on the upper end of the support plate 21, start the servo motor 27, drive the bidirectional threaded screw 26 to rotate, cooperate with the limit block 28 and the limit rod 29, and then drive the front and rear limit plates 23 to approach each other through the driving block 25, clamping the lower end of the ice cube, and at the same time, the anti-slip convex points 24 are evenly distributed on one side to prevent the ice cube from sliding on the upper end of the support plate 21 during the loading and unloading process. By arranging the limit mechanism 2 at the upper end of the lifting bracket 3, the ice cube is not prevented from sliding on the upper end of the support plate 21 during the loading and unloading process. It will easily slide on the upper end of the limiting mechanism 2, preventing the ice from sliding and causing damage to the ice, and at the same time reducing the probability of safety accidents during the loading and unloading of ice. When the ice moves to the upper end of the support plate 21, the reduction motor 14 is started, and the sprocket 16 is driven to rotate through the drive shaft 15, and then the ice at the upper end of the limiting mechanism 2 is moved up to the rear of the transport vehicle through the cooperation of the drive chain 17, the counterweight block 18 and the drive seat 19, and the servo motor 27 is started to release the clamping of the ice, push the ice into the interior of the transport vehicle, and complete the loading.
