[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-6, A gantry crane safety device with AI analysis function, including two support plates 3. At the top of each of the two support plates 3, a support frame 2 is welded. At the top of the two support frames 2, a top plate 1 is welded. A groove 24 is formed inside the support frame 2, and a plurality of card slots 23 are evenly arranged inside the support frame 2. A sliding frame 4 is slidably connected inside the groove 24. At the top of the sliding frame 4, two symmetrically arranged shells 27 are slidably connected. Inside each shell 27, a wedge-shaped block 25 that is clamped with the card slot 23 is slidably connected. A elastic force component is arranged between the wedge-shaped block 25 and one inner wall of the shell 27. The elastic force component includes two springs 31 arranged between the wedge-shaped block 25 and one inner wall of the shell 27. One end of the spring 31 is fixed to the wedge-shaped block 25, and the other end is fixed to one inner wall of the shell 27. Inside each of the two springs 31, a telescopic rod 30 is arranged. One end of the telescopic rod 30 is fixed to the wedge-shaped block 25, and the other end is fixed to one inner wall of the shell 27. Through the elastic force of the two springs 31, the wedge-shaped block 25 is clamped into the card slot 23, and through the telescopic rod 30, the sliding of the wedge-shaped block 25 is made more stable. On both sides of the sliding frame 4, a driving component for driving the shell 27 to move is provided. The driving component includes two symmetrically arranged fixing plates 26 fixed to both sides of the sliding frame 4 by bolts. At the top of each of the two shells 27, a connecting plate 28 is welded. One side of the connecting plate 28 is rotatably connected by a bearing to a lead screw 29 that is threadedly connected to the fixing plate 26, and one end of the lead screw 29 passes through the connecting plate 28. By rotating the lead screw 29, the lead screw 29 drives the connecting plate 28 and the shell 27 to move backward, and the shell 27 drives the wedge-shaped block 25 to disengage from the card slot 23, so that the sliding frame 4 can move downward. The operation is simple and easy to use. At the top of the top plate 1, a lifting component for pulling the sliding frame 4 to move up and down is provided. The lifting component includes two fixing blocks 9 fixed to the top of the top plate 1 by bolts. Inside the two fixing blocks 9, a connecting shaft is rotatably connected by a bearing. At both ends of the connecting shaft, winding rollers 8 are key-connected. A pull rope 7 whose one end is fixed to the winding roller 8 is wound around the circumferential outer side of the winding roller 8, and the other end of the pull rope 7 passes through the top plate 1 and is fixed to the sliding frame 4. Start the power component, the power component drives the connecting shaft to rotate, the connecting shaft drives the two winding rollers 8 to rotate simultaneously, and the two winding rollers 8 respectively wind or unwind the two pull ropes 7, so that the sliding frame 4 moves up and down. Start the lifting component, the lifting mechanism drives the sliding frame 4 to move upward, the sliding frame 4 drives the two wedge-shaped blocks 25 to move upward, and at the same time, the inclined surface of the card slot 23 squeezes the inclined surface of the wedge-shaped block 25, so that the wedge-shaped block 25 moves backward and disengages from the card slot 23. Continuing to move upward, the wedge-shaped block 25 will be clamped into another card slot 23 due to the elastic force of the elastic force component, and so on. When the pull rope 7 breaks, the flat surface at the bottom of the wedge-shaped block 25 will block the sliding frame 4, so that the sliding frame 4 stops moving downward, thereby preventing the workpiece on the gantry crane safety device from falling, causing certain economic losses, and avoiding the risk of injury to the operator and surrounding staff.

[0024] In the present invention, a power assembly for driving the connecting shaft to rotate is provided at the top of the top plate 1. The power assembly includes a mounting bracket 5 fixed to the top of the top plate 1 by bolts. A worm 6 is rotatably connected between the inner walls on both sides of the mounting bracket 5 through bearings. A worm gear 10 meshing with the worm 6 is connected to the outer circumference of the connecting shaft by a key. A servo motor for driving the worm 6 to rotate axially is fixed to one side of the mounting bracket 5 by bolts. When the servo motor is started, the output shaft of the servo motor drives the worm 6 to rotate, the worm 6 drives the worm gear 10 to rotate, and the worm gear 10 drives the connecting shaft to rotate, thereby realizing the winding or unwinding of the pulling rope 7 by the winding roller 8. Moreover, through the worm 6 and the worm gear 10, self-locking is realized, so that the connecting shaft will not rotate due to external force.

[0025] In the present invention, a lifting assembly is provided at the bottom of the sliding carriage 4. The lifting assembly includes a plurality of fixing brackets 16 welded to both sides of the sliding carriage 4. A guiding bracket 18 is slidably connected between the inner walls of two adjacent fixing brackets 16. Two sliders 17 are slidably connected to the outside of the guiding bracket 18. The bottom of the slider 17 is rotatably connected to a connecting bracket 22 through a bearing. A hook 20 is rotatably connected between the inner walls on both sides of the connecting bracket 22 through bearings. Pressure sensors 15 are fixed to the bottoms of the plurality of fixing brackets 16 by bolts. The model of the pressure sensor 15 is the CH-PTSHT spoke-type sensor. The pressure sensor 15 is connected to the AI terminal via Bluetooth, so that the data of the pressure sensor 15 is transmitted to the AI terminal. Through the data analysis of the AI terminal, it is possible to accurately evaluate whether the overhead crane safety device can bear the weight of a specified workpiece, realizing the precise discrimination of the safety performance of the overhead crane safety device, thereby greatly improving the safety of the overhead crane safety device. By sliding the plurality of sliders 17, the sliders 17 are slid to appropriate positions, so that it is convenient for the hook 20 to lift workpieces of different sizes, greatly improving the usage range of the overhead crane safety device.

[0026] In the present invention, a baffle 21 is rotatably connected between the two sides of the plurality of hooks 20. A torsion spring 19 is clamped to one side of each of the plurality of hooks 20, and the other end of the torsion spring 19 is fixed to the baffle 21. Through the cooperation of the baffle 21 and the torsion spring 19, one end of the baffle 21 contacts the end of the hook 20, thereby preventing the workpiece hooked by the hook 20 from shaking and disengaging from the hook 20, causing the workpiece to fall.

[0027] In the present invention, a moving assembly is provided at the bottom of the two support plates 3. The moving assembly includes sliding grooves 11 respectively formed at the bottoms of the two support plates 3. A sliding plate 14 is slidably connected in the sliding grooves 11. A plurality of universal wheels 12 are uniformly fixed to the bottom of the sliding plate 14 by bolts. A self-locking cylinder 13 is fixed to the top of the support plate 3 by bolts, and the piston end of the self-locking cylinder 13 passes through the support plate 3 and is fixed to the sliding plate 14. By simultaneously starting the two self-locking cylinders 13, the two self-locking cylinders 13 simultaneously drive the universal wheels 12 to contact the ground, and at the same time the support plate 3 is separated from the ground contact, thus facilitating the movement of the overhead crane safety device and facilitating the overhead lifting of workpieces beyond the working range of the overhead crane safety device, greatly saving labor.

[0028] The working principle of this embodiment: During use, slide a plurality of sliders 17 to make the sliders 17 slide to appropriate positions, then hang the workpiece on a plurality of hooks 20, and then start the servo motor. The output shaft of the servo motor drives the worm 6 to rotate, the worm 6 drives the worm gear 10 to rotate, the worm gear 10 drives the connecting shaft to rotate, and the connecting shaft drives the two winding rollers 8 to rotate simultaneously. The two winding rollers 8 respectively wind the two pulling ropes 7, so that the carriage 4 moves upward. The carriage 4 drives the workpiece on the hook 20 to move upward. At the same time, the carriage 4 drives the two wedge-shaped blocks 25 to move upward. At the same time, the inclined surface of the card slot 23 will squeeze the inclined surface of the wedge-shaped block 25, causing the wedge-shaped block 25 to move backward and thus fall off the clamping connection in the card slot 23. Continuing to move upward, the wedge-shaped block 25 will be snapped into another card slot 23 due to the elastic force of the spring 31, and so on, thereby lifting the workpiece and facilitating workpiece processing.
