[0016] Furthermore, the cylinder drives the connecting plate to move upward, and the connecting plate drives the connecting frame on the fixed frame to slide on the inner wall of the mounting plate, so that the disc at one end of the slider moves upward and pulls the hook inside the disc upward, thereby buffering the cable during hoisting and preventing the cable from breaking due to prolonged tension.

[0017] Furthermore, by having the weight contact the buffer plate, the buffer plate compresses the second spring, and the second spring deforms and rebounds back onto the buffer plate, reducing the swing amplitude of the weight when the worktable stops, thus stabilizing the movement of the weight and improving equipment safety.

[0018] This invention achieves secure fixing of the hook during hoisting, preventing swaying that could cause insufficient tension on the cable. This ensures even transport and cushions the cables during transit to prevent breakage, guaranteeing a smooth and safe transport of the goods. The overall coefficient is high.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 like Figure 1-2 As shown, the present invention proposes a metal railing hoisting device, which includes a main body 1, an mounting plate 5 fixedly installed at the bottom of the main body 1, an operating platform 2 slidably installed on the main body 1 for controlling the hoisting process, a cable 7 rotatably installed inside the operating platform 2, and a hook 6 rotatably installed at one end of the cable 7 for hoisting and transporting objects. The stabilizing mechanism is located at the bottom of the main body 1 to fix the hook 6 during horizontal sliding, so as to prevent the hook from shaking during transportation and causing the cable 7 to break, thus improving safety. In addition, the auxiliary mechanism is set at the bottom of the operating platform 2 to prevent the cable 7 from being in a taut state during the hoisting process, so that the cable 7 can have time to buffer during the hoisting operation and avoid the cable 7 from bursting due to being in a taut state for a long time. It is worth noting that the buffer mechanism is set on the support leg 3 to buffer the object lifted by the hook 6 after it stops moving horizontally, thus preventing it from swaying and improving the safety of the lifting operation.

[0023] like Figure 2-4As shown, this embodiment also includes a stabilizing mechanism, which includes mounting plates 5 fixedly installed on both sides of the bottom of the operating table 2. A connecting frame 28 is slidably installed between the two mounting plates 5. Slider blocks 22 are slidably installed at both ends of the connecting frame 28. A motor 34 is slidably installed at the bottom of the main body 1 to increase power. A threaded rod 20 is fixedly installed on the output shaft of the motor 34. A positioning plate 19 is rotatably installed on the threaded rod 20. When the threaded rod 20 rotates, the positioning plate 19 can move on the threaded rod 20. A connecting rod 21 is hinged to the slider 22 and is hinged to the positioning plate 19. A disc 9 is fixedly installed on the side of the slider 22 near the hook 6. The top of the disc 9 is hollow and has a notch so that the cable 7 will not obstruct the disc 9 from contacting the hook 6. An internally fixed spring 26 is installed, and a pressing plate 8 is fixedly installed at one end of the spring 26. The pressing plate 8 is slidably connected to the inner wall of the disc 9. The connection point of the pressing plate 8 and the hook 6 is at the same horizontal height, which facilitates the fixing of the hook. When the motor 34 rotates, the output shaft of the motor 34 drives the threaded rod 20 to rotate. Since the positioning plate 19 is hinged to the connecting rod 21, and the slider 22 hinged to the connecting rod 21 is horizontally slidably connected to the connecting frame 28, the threaded rod 20 can drive the sliders 22 on both sides of the connecting frame 28 to move closer to each other when it rotates. The disc 9 at one end of the slider 22 moves closer together with the slider 22. The pressing plate 8 on the disc 9 contacts the hook 6 and presses it, so that the two sides of the hook 6 enter the disc 9 to fix the hook 6 and prevent the hook 6 from shaking.

[0024] Example 2 like Figure 5-6 As shown, this embodiment also includes an auxiliary mechanism, which includes a cylinder 16 fixedly installed at the bottom of the main body 1. A connecting plate 11 is fixedly installed on the piston rod of the cylinder 16. Fixed frames 23 are fixedly installed at both ends of the connecting frame 28. The fixed frames 23 are fixedly connected to the connecting plate 11. When the cylinder 16 is started, the piston rod of the cylinder 16 drives the connecting plate 11 to move upward. The connecting plate 11 drives the connecting frame 28 on the fixed frame 23 to slide on the mounting plate 5. The connecting frame 28 drives the disc 9 at one end of the slider 22 to move upward. Since the hook 6 is inside the disc 9, the connecting frame 28 can give the hook 6 an upward force when it moves upward, reducing the tension of the cable 7 hanging the object, so that the cable 7 is not in a taut state for a long time during the hanging process, and improving the service life of the cable 7.

[0025] like Figure 2-8As shown, this embodiment also includes a buffer mechanism, which includes a buffer groove 33 fixedly opened on the support leg 3. A support plate 17 is slidably installed in the buffer groove 33. A second spring 32 is fixedly installed at one end of the support plate 17. A buffer plate 4 is fixedly installed between the two support plates 17. When the operating table 2 drives the weight on the hook 6 to move, it reaches the designated position and finally contacts the buffer plate 4. The buffer plate 4 presses the second spring 32, and the second spring 32 deforms and rebounds, reducing the impact force of the weight and reducing the swing amplitude of the weight.

[0026] Example 3 like Figure 6-7 As shown, guide grooves 35 are provided on both sides of the connecting frame 28, guide blocks 27 are fixedly installed on both sides of the slider 22, the guide blocks 27 are located in the guide grooves 35, the inner wall of the mounting plate 5 is provided with a sliding groove 14, the two ends of the connecting frame 28 are fixedly installed with protrusions 24, the protrusions 24 are slidably connected with the sliding grooves 14, the disc 9 is slidably installed with guide posts 25, the first spring 26 is sleeved on the guide posts 25, one end of the operating table 2 is fixedly connected to the extrusion plate 8, and a fixing rod 29 is fixedly installed on the fixing frame 23, the fixing rod 29 is fixedly connected to the connecting plate 11.

[0027] like Figure 4 , Figure 6 and Figure 10 As shown, a connecting rod 18 is fixedly installed on the top of the connecting plate 11, and a stop block 15 is fixedly installed on one end of the connecting rod 18. The stop block 15 contacts one end of the hook 6. A pressure sensor 36 is installed on the stop block 15. A controller is installed inside the operating table 2. The output end of the pressure sensor 36 is connected to the input end of the controller. The output end of the controller is electrically connected to the start end of the operating table. When the pressure sensor 36 detects that the hook 6 is in contact with it, it transmits a signal to the controller. The controller controls the operating table 2 to stop lifting the hook 16, so that the hook 6 can stop at the same horizontal height as the disc 9, which facilitates the fixing of the hook 6 by the disc 9.

[0028] like Figure 3-9 As shown, a slide rod 31 is fixedly installed on the main body 1, and the operating table 2 is slidably connected to the slide rod 31. An installation groove 30 is opened on the inner wall of the operating table 2. A rotating shaft 13 is rotatably installed at both ends of the operating table 2, and a rotating wheel 12 is rotatably installed at one end of the rotating shaft 13. The rotating wheel 12 is located in the installation groove 30. When the rotating wheel 12 is started, it can drive the operating table 2 to slide on the slide rod 31 to realize the lifting and transportation of heavy objects. A fixed frame 10 is fixedly installed at the bottom of the connecting plate 11, and the fixed frame 10 is fixedly connected to the motor 34.

[0029] Working principle: Start the operating table 2, which releases cable 7, allowing hook 6 to fall. A heavy object is hung on hook 6. Then, tighten cable 7, allowing hook 7 to lift the object upwards. When hook 7 reaches stop 15, start motor 34. The output shaft of motor 34 drives threaded rod 20 to rotate. Because the positioning plate 19 is hinged to connecting rod 21, and the slider 22 hinged to connecting rod 21 is horizontally slidably connected to connecting frame 28, the threaded rod 20, when rotating, drives the sliders 22 on both sides of connecting frame 28 to move closer together. The disc 9 at one end of slider 22 moves closer with slider 22, and the pressing plate 8 on disc 9 contacts and presses against hook 6, causing both sides of hook 6 to enter the disc 9, fixing hook 6 and preventing it from shaking. Start cylinder 16; the piston rod of cylinder 16 drives connecting plate 11 upwards. Connecting plate 11 drives connecting frame 2 on fixed frame 23. 8. Slide on mounting plate 5. Connecting frame 28 drives disk 9 at one end of slider 22 to move upward. Since hook 6 is inside disk 9, connecting frame 28 can give hook 6 an upward force when moving upward, reducing the tension of cable 7 suspending the object. At this time, the rotating wheel 12 on operating platform 2 starts. The rotating wheel 12 drives operating platform 2 to move on sliding rod 31. After transporting the heavy object to the designated position, the heavy object contacts buffer plate 4. Buffer plate 4 compresses the second spring 32. The second spring 32 deforms and rebounds, reducing the impact force of the heavy object and reducing the swing amplitude of the heavy object. After the heavy object is stable, the piston rod of cylinder 16 extends, motor 34 reverses, cancels the fixation of hook 7, and operating platform 2 releases cable 7 to transport the heavy object to the ground. This realizes the fixation of hook during hoisting, avoids uneven force on cable caused by shaking, and buffers the cable during transportation to prevent cable breakage. The transport of objects is stable and has a high safety factor.
