Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1-4 This utility model provides a technical solution: a crane travel anti-sway device, including a boom body 1, a movable vehicle 2 that can move along a track is provided at the bottom of the boom body 1, a winch 3 is installed at the center of the bottom of the movable vehicle 2, the winch 3 is suspended by a hook 4 through a cable, and anti-sway components are symmetrically arranged on the front and rear sides of the winch 3. The anti-sway mechanism can restrict the cable, thereby reducing the amplitude of cable sway when lifting and transferring objects using the hook 4, and preventing the cable sway from causing the object to slide, tilt or fall.

[0029] Reference Figures 1-4 In a preferred embodiment, an anti-sway mechanism is provided, which includes a mounting frame 5, a limiting frame 6, and a constraint plate 7. A pair of parallel mounting frames 5 are fixed to the front and rear sides of the bottom of the winch 3, respectively. Multiple spaced limiting frames 6 have their first ends fixedly connected to the mounting frames 5. Each limiting frame 6 is arranged along the extension direction of the cable. The constraint plate 7 is located at the outer end of the limiting frame 6. The mounting frame 5 can install the limiting frame 6, and the constraint plate 7 can cooperate with the limiting frame 6 to restrict the cable after moving towards the limiting frame 6, thereby reducing the degree of cable sway.

[0030] Reference Figures 1-4In a preferred embodiment, the limiting frame 6 has mounting grooves 8 on both sides. A guide rod 9 is installed on the inner wall of the mounting groove 8. The outer end of the guide rod 9 is connected to the constraint plate 7. A spring 10 is installed on the inner wall of the mounting groove 8. The spring 10 is sleeved on the surface of the guide rod 9, and the other end of the spring 10 is connected to the constraint plate 7. After the constraint plate 7 is squeezed, the constraint plate 7 can move towards the limiting frame 6, so that the limiting frame 6 and the constraint plate 7 cooperate to restrict the cable. The guide rod 9 can guide the constraint plate 7 to prevent the constraint plate 7 from deviating.

[0031] Reference Figures 1-4 In a preferred embodiment, a first fitting pad 11 is installed on the inner side of the limiting frame 6, and a second fitting pad 12 is installed on the inner side of the constraint plate 7. When the constraint plate 7 and the limiting frame 6 restrict the cable, the first fitting pad 11 and the second fitting pad 12 can fit together and adhere to the surface of the cable, and the dust on the surface of the cable can be cleaned when the cable is wound up.

[0032] Reference Figures 1-3 In a preferred embodiment, a drive motor 13 is installed at the bottom of the inner wall of the mounting frame 5. A lead screw 14 is installed at the output end of the drive motor 13. A threaded sleeve 15 is installed on the surface of the lead screw 14. A connecting plate 16 is installed on the surface of the threaded sleeve 15. The connecting plate 16 is slidably engaged with the mounting frame 5. An extension plate 17 is installed on the inner side of the connecting plate 16. A pressing block 18 is installed on the top of the extension plate 17. The right side of the top of the pressing block 18 is inclined. This allows the drive motor 13 to drive the connecting plate 16 to move through the lead screw 14 and the threaded sleeve 15 after starting. This causes the connecting plate 16 to drive the pressing block 18 to move upward through the extension plate 17 and press the constraint plate 7. This allows the constraint plate 7 to fit against the limiting frame 6, thereby restricting the cable.

[0033] Reference Figures 1-3 In a preferred embodiment, a mounting plate 19 is installed on the top of the limiting frame 6, and a mounting pin 20 is provided on the inner side of the mounting plate 19. The mounting pin 20 passes through the mounting plate 19 and is threadedly connected to the mounting frame 5. The limiting frame 6 can be disassembled by removing the mounting pin 20, so that the first bonding pad 11 and the second bonding pad 12 can be disassembled and replaced after the limiting frame 6 is disassembled, thus avoiding the first bonding pad 11 and the second bonding pad 12 from being worn out due to long-term use and becoming unusable.

[0034] Specifically, the working process or principle of this crane's anti-sway device is as follows: During use, the winch 3 is started, and the cable and hook 4 are lowered, allowing the hook 4 to be used for lifting and transporting objects. Before lifting and transporting the object, the drive motor 13 is started, causing the drive motor 13 to rotate the lead screw 14. This, in turn, causes the lead screw 14 to move the connecting plate 16 upwards via the screw sleeve 15. The connecting plate 16, through the extension plate 17, causes the pressing block 18 to move upwards, so that the inclined surface of the pressing block 18 is approximately... The clamping plate 7 is squeezed, which causes the constraint plate 7 to press against the spring 10 and move towards the limiting frame 6. This allows the first contact pad 11 and the second contact pad 12 to cooperate and adhere to the surface of the cable. Thus, when the cable is wound up or the object is lifted, the first contact pad 11 and the second contact pad 12 cooperate to clean the dust on the surface of the cable. Moreover, when the object is transferred, the constraint plate 7 and the limiting frame 6 can restrict the cable, reduce the swaying amplitude during the transfer of the object, and prevent the object from shaking during lifting and transfer, which could cause the object to tilt or fall.

[0035] It should be noted that the mobile vehicle 2, the winch 3 and the drive motor 13 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
