[0002] A vertical lift cabinet is an automated transportation device. It usually consists of a main cabinet and two supporting plates on both sides. Pallets and goods are inserted from one side and transported into the lifting mechanism inside the cabinet by rollers. After it is raised to a certain height, it can be pushed out and the goods can be removed from the supporting plates on the other side.
[0003] Currently, most vertical lifting cabinets require workers to pre-weigh the goods to be transported. If the goods are overweight, they cannot withstand the load, causing the panels to collapse and the rollers to stop transporting due to insufficient load. Manual weighing is time-consuming and physically demanding, making it difficult to improve the conveying efficiency of the equipment.
[0004] Now, a novel vertical lifting cabinet with an overload warning mechanism is proposed to solve the above problems. Utility Model Content

Gears are movably connected between the front and rear ends inside the slots. Tracks are longitudinally welded to the front and rear ends of the two sides inside the cabinet body, and gear racks are longitudinally fixed on the sides of the tracks. Worms are movably connected to the front and rear ends of the lifting plate. Worm wheels are movably connected to the two sides of the front and rear ends of the lifting plate. Motor II is fixed to the front and rear ends of the left side of the lifting plate. Conveyor rollers are movably connected to the four corners inside the lifting plate. Motor III is fixed to the two sides of the front and rear ends of the lifting plate. Casters are fixed to the four corners of the lower part of the cabinet body.

[0030] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, based on the length of the goods, motor 21 rotates the screw 23 in the horizontal groove 22 of the lifting plate 2. When moving the threaded block 25, the position of the sleeve block 24 and the baffle 15 is adjusted. Then, motor 26 is turned on and the toothed disc 28 connected to its output end is rotated. The baffle 15 with toothed groove 27 is raised and lowered vertically to adjust the position of this object to block the goods and prevent the object from shaking during vertical movement. After the lifting plate 2 moves to a suitable height, the baffle 15 is lowered to allow the goods to continue moving.
[0031] Support plates 6 are fixed on both sides of the outside of the cabinet 1, and a gravity sensor 9 is fixed at the center of the inside of the support plate 6. Rollers 8 are movably connected to the four corners of the inside of the support plate 6. Motor 7 is fixed at the front and rear ends of the outside of the support plate 6. Angle steel 29 is fixed between the support plate 6 and the cabinet 1. Screw holes 13 are longitudinally arranged on the surface of the track 12. Vertical grooves 11 are longitudinally arranged inside both sides of the cabinet 1, and sliding frames 10 are movably connected in the vertical grooves 11. Two sets of positioning plates 30 are fixed on the sides of the front and rear ends of the sliding frame 10, and screws 31 are threaded between the positioning plates 30 and the screw holes 13.

[0032] Specifically, such as Figure 1 and Figure 5 As shown, the support plate 6 is fixed at different heights on both sides of the cabinet 1 using angle steel 29, bolts, etc. Then, the sliding frame 10 is moved along the vertical groove 11 inside both sides of the cabinet 1, and after aligning the positioning piece 30 with the screw hole 13, the screw 31 is screwed in for reinforcement. The position of the sliding frame 10 is adjusted according to the installation height of the support plate 6 to limit the transport of goods on the lifting plate 2 inside the cabinet 1.
[0033] Working Principle: In use, the support plate 6 is first fixed to different heights on both sides of the cabinet 1 using angle steel 29, bolts, etc. Then, the sliding frame 10 is moved along the vertical grooves 11 inside both sides of the cabinet 1. After aligning the positioning piece 30 with the screw hole 13, screws 31 are screwed in for reinforcement. The position of the sliding frame 10 is adjusted according to the installation height of the support plate 6 to limit the transport of goods onto the lifting plate 2 inside the cabinet 1. Once the goods are on the lifting plate 2, the motor 14 is started and the worm gear 4 is rotated to turn the worm wheels 5 on both sides. The worm wheels 5 rotate their respective connected gears 16, causing the lifting plate 2 and other items to move along the toothed rack 17 of the track 12 in the slot 18. The self-locking structure prevents the lifting plate 2 from falling, ensuring safety. To ensure the stability of the goods during movement, gravity sensors 9 connected to the controller are installed in the support plates 6 on both sides. When the motor 7 controls the roller 8 to push the goods, the weight of the goods can be detected in real time. According to the length of the goods, the screw 23 in the horizontal groove 22 of the lifting plate 2 is rotated by the motor 4 21. When the threaded block 25 is moved, the position of the sleeve block 24 and the baffle 15 is adjusted. Then the motor 5 26 is turned on and the toothed disc 28 connected to its output end is rotated to vertically raise and lower the baffle 15 with toothed groove 27. The position of this object blocking the goods is adjusted to prevent the object from shaking during vertical movement. After the lifting plate 2 moves to a suitable height, the baffle 15 is lowered, and the conveyor roller 20 controlled by the motor 3 19 transfers the goods to the other side.
