Description

Technical Field

[0001] The invention relates to the technical field of anti-swaying of crane ropes, and in particular to a protective device for preventing the hoisting ropes of a crane from swaying. Background Art

[0002] A crane is a device used for lifting and transporting cargo. For example, a gantry crane uses a gantry frame, moving parts, and a winch to control the ropes for lifting and transporting. During the actual lifting process, the ropes are driven by the moving parts to move the cargo.

[0003] For example, the patent with application number: CN202410171697.2 discloses a crane hoist rope anti-sway protection device, which relates to the field of crane technology, including a crane electric hoist housing, a lifting shaft and a servo motor. A pair of movable pulleys are provided on the hook frame, and the pull rope passes through the fixed pulley. The two ends of the pull rope pass through a pair of movable pulleys in opposite directions respectively. The bottom end of the crane electric hoist housing is provided with a fixed rod with a buffering and blocking function, and an oil tank is installed on the fixed rod. The present invention provides a crane hoist rope anti-sway protection device, and the lifting shaft reels the pull rope, and the pull rope is reeled in from both ends of a pair of movable pulleys to prevent the hook frame from swinging toward the reeling end when one end reels the pull rope, thereby preventing shaking.

[0004] Based on the above, the inventors found that the current crane lifting rope anti-sway protection device is not convenient for realizing automatic compensation and correction when lifting goods. In an environment where the rope is long or the wind is strong, its anti-sway effect is not good, and it is not convenient to detect the offset of the rope during the movement and lifting of the goods. The inertia force of the goods when being towed is large, posing a safety hazard. At the same time, it is not convenient to press down and stabilize the hook. The stability of the goods when suspended statically is poor. At the same time, the rope's anti-breaking protection effect is not good, and there is a risk of goods falling. Summary of the Invention

The use of the counterweight lifting part 2 can have stronger stability in environments such as bad weather. When the wind is strong, the downward pressure cylinder 203 can be used to control the downward pressure to stabilize the goods in time.

This structure can be mechanically controlled automatically, and the detection is stable and durable. It can automatically control the lock when the structure loses traction pressure, and automatically control the principle that the rope connecting shaft 601 and the lifting adapter rod 201 lose the downward pressure of their own weight after the rope body 602 breaks. At the same time, the lifting control rod 604 used in this structure is provided with a slide groove on the inside of the slide groove, which does not affect the normal traction and movement of the rope connecting shaft 601 inside it.

[0044] The working principle of this embodiment is as follows: first, a hook is installed on the hook connecting plate 303, and the two lifting guide rods 101 and the pressurized stabilizing rod 102 are respectively installed on the crane gantry, and the rope body 602 is connected to the winch on the crane. The cargo is hoisted on the hook on the hook connecting plate 303. When the cargo is hung manually, the worker rotates and presses the screw rod 305 to drive the pressing plate 307 on the adapter ball head 306 to press down to fit the cargo. When the rope body 602 is wound by the winch on the crane, the cargo is pulled. At this time, the lifting adapter The supporting rod 201 is lifted together, and the downward force is generated by its own weight and the counterweight of the counterweight block 202, which helps to improve the stability of the moving block 301 and makes the rope body 602 less likely to tilt. At the same time, when emergency transportation needs to be stopped in an environment with strong winds, the downward pressure cylinder 203 can be used to drive the propelling ball head column 204 to move and insert it into the inclined groove on the pressurized stabilizing rod 102. By utilizing the characteristics of the inclined groove, when the propelling ball head column 204 presses against the inclined surface of the inclined groove on the pressurized stabilizing rod 102, it will be squeezed by the inclined groove, driving the lifting adapter rod 201 to produce The downward pressure is generated, and the stable moving block 301 is pressed down again. Under the action of wind, or when the goods are moved by the crane moving component, it is easy to cause the rope body 602 to tilt and deflect. At this time, the touch column 505 on one side is squeezed, and the squeezing control micro switch 504 is energized, so that the drive motor 401 on the same side drives the drive compensation wheel 402 set to drive the moving block 301 to move, resisting the shaking and displacement of the rope body 602 caused by wind or the movement of the crane moving component, and achieving compensation. Its driving direction is driven by the drive motor 401. The movable block 301 moves in the opposite direction of the wind direction; after the rope main body 602 breaks, the lifting adapter rod 201 and the stable moving block 301 will lose traction at the same time and fall freely. At this time, under the squeezing of the compression spring 603, the rope connecting shaft 601 will drive the lifting control rod 604 and the inclined plane control block 6041 to move downward, releasing the limit of the inclined plane control block 6041 on the limit head 702. At this time, under the pull of the return spring 704, the limit head 702 can be inserted and positioned in the limit inclined block 1011 for locking, thereby realizing the protective locking work.
