[0002] Traditional factory handling generally relies on manual handling or the assistance of trailers to carry goods, which is inefficient and costly. In order to improve handling efficiency and reduce handling costs, human-driven forklifts have emerged. Handling robots integrate cargo handling and transportation through trucks and robotic arms. At the same time, by adding item storage warehouses to trucks, the amount of cargo that can be carried at a time by cargo handling robots is increased, thereby improving handling efficiency and further reducing handling costs.

[0003] A Chinese patent with publication number CN219585770U is searched and discloses a cargo handling robot, including a transport vehicle, on which a lifting frame is fixedly installed, a sliding groove is provided on the inner wall of the lifting frame, and a handling mechanism is installed on the lifting frame; the handling mechanism includes a load-bearing frame.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] When an existing cargo handling robot pushes an object for loading, it is necessary to loosen the clamping plate in advance, which causes the object to easily shift when being pushed, and thus the object cannot be loaded neatly, thereby reducing the loading effect of the object. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a cargo handling robot, in which the second servo motor drives the bidirectional threaded shaft to rotate, and the bidirectional threaded shaft drives two fixed plates and a rotating column to move. The rotating column is rotating, so that the material can be loaded and the rotating column can limit the material, so that the material can be loaded neatly.

[0007] The technical solution to achieve the purpose of the utility model is: a cargo handling robot, including a transport vehicle, the top of the transport vehicle is fixedly connected to a fixed frame, the fixed frame is slidably connected to two sliders, one side of the two sliders is commonly fixedly connected to a placement frame, and also includes;

[0008] A clamping mechanism, wherein the clamping mechanism is located on the placement rack;

[0010] In some embodiments, the two fixed plates are fixedly connected to a U-shaped plate on the sides away from each other, and the two U-shaped plates are fixedly connected to a fixed column on the sides close to each other. A movable groove is provided at one end of the two fixed columns, and a movable column is slidably connected in the two movable grooves. A pressure plate is fixedly connected to one end of the two movable columns, and an extrusion spring is sleeved on the two fixed columns, and the two ends of the extrusion spring are respectively fixedly connected to the U-shaped plate and the pressure plate.

[0011] In some embodiments, two fixing blocks are rotatably sleeved on the bidirectional threaded shaft, and one end of the two fixing blocks is fixedly connected to one side of the placement rack.

[0012] In some embodiments, the two pressing plates are made of stainless steel, and the sides of the two pressing plates close to each other are configured as a smooth surface.

[0013] In some embodiments, a telescopic hydraulic cylinder is fixedly connected to one side of the placement rack, and a push plate is fixedly connected to the output end of the telescopic hydraulic cylinder.

[0027] like Figure 3 As shown, in one embodiment, in order to ensure the stability of the fixed column 26, the fixed column 26 is fixed to the U-shaped plate 25 by welding, the two sides of the fixed plates 23 that are away from each other are fixedly connected with the U-shaped plate 25, and the sides of the two U-shaped plates 25 that are close to each other are fixedly connected with the fixed column 26, one end of the two fixed columns 26 is provided with a movable groove, and the two movable grooves are slidably connected with a movable column 27, one end of the two movable columns 27 is fixedly connected with a pressing plate 28, and the two fixed columns 26 are sleeved with an extrusion spring 29, and the two ends of the extrusion spring 29 are fixedly connected to the U-shaped plate 25 and the pressing plate 28 respectively; through the setting of the pressing plate 28, the pressing plate 28 cooperates with the fixed column 26, the movable column 27 and the extrusion spring 29 to achieve the fixation of the material.

[0028] like Figure 2 As shown, in one embodiment, two fixing blocks 22 are rotatably sleeved on the bidirectional threaded shaft 21, and one end of the two fixing blocks 22 is fixedly connected to one side of the placement frame 16; through the provision of the fixing blocks 22, the stability of the bidirectional threaded shaft 21 is improved.
