Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and specifically to a wind-proof gantry lifting device and a usage method thereof. Background Art

[0002] A gantry crane is a deformation of a bridge crane, also known as a gantry crane, mainly used for the loading and unloading operations of outdoor freight yards, material yards, and bulk goods. The gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability, and strong versatility. When a common gantry crane is used outdoors in a place with strong wind for a long time, the external wind will blow the main beam frame at the top of the crane for a long time. When driving the goods loading and unloading to move against the wind, the wind blowing towards the main beam frame will be greater, resulting in a large amount of kinetic energy consumption when the crane moves. And when the wind is strong, the overall center of gravity of the crane will shift. In some areas prone to wind disasters, when in the non-working state, it is very likely to move along the slide rail without anyone operating under the thrust of strong wind, which is not only prone to tipping over, but also has potential safety hazards of causing personal safety and economic losses.

[0003] The existing authorized publication number is: CN114890303B, which discloses a wind-proof gantry lifting device for large-span lifting. Through the cooperation of wind-proof cables with locking mechanisms and positioning mechanisms, it is convenient to effectively improve the wind resistance effect of the gantry lifting device on windy days, and at the same time improve the anti-slip effect of the gantry lifting device on windy days, and it is convenient to play a role of multiple limit locking for the gantry lifting device. Among them, the positioning mechanism includes that the inner bottom surface of the movable strip and the positioning box are equidistantly provided with a number of through holes in cooperation with the limit inserts; the top surface of the positioning strip is equidistantly provided with a number of positioning holes in cooperation with the limit inserts; it is convenient to play a role of limiting and fixing the moving seat, and at the same time extend the service life of the braking mechanism inside the moving seat. However, when the above lifting equipment is in use, since the limit inserts are arranged in an equidistant array, and the limit inserts move together with the lifting device, while the positioning holes do not move, it is necessary for the staff to continuously adjust the position of the lifting device during use so that the limit inserts are aligned with the positioning holes before it can be used. And because the positioning mechanism and the locking mechanism are set in a linkage state, when the limit inserts are not aligned with the positioning holes, the locking mechanism cannot be used either, making it inconvenient to quickly protect the lifting device in some emergency situations.

[0004] Based on this, a wind-proof gantry lifting device and a usage method thereof are now provided, which can eliminate the drawbacks of the existing device. Summary of the Invention

At the upper ends inside the installation frame 34, first racks 33 are fixedly arranged. On one side of each first rack 33, first gears 32 are symmetrically arranged in a matching manner. At the bottom ends of the lower crossbeams 13, fourth fixing boxes 55 are fixedly arranged. Inside the fourth fixing boxes 55, there are limiting mechanisms for pushing the first gears 32 to move and then assisting in fixing the main beam frame 11. On the upper ends of the lower crossbeams 13, installation side plates are fixedly arranged. On one side of each installation side plate, a fixing plate 40 is fixedly arranged. Inside the fixing plate 40, there are supporting mechanisms for supporting the main beam frame 11. Through the limiting mechanism, it is convenient to push the first gears 32 to move, so that the first gears 32 are engaged with the first racks 33, and then assist in fixing the main beam frame 11. The supporting mechanism is convenient for assisting in supporting the main beam frame 11;

[0037] On the upper end of the main beam frame 11, there is a traveling trolley. On the traveling trolley, there is a hoisting component. At the end of the hoisting component, there is a hook 15.

Second worms 51 are meshed with the second worm wheels 50. Fourth support plates are rotatably provided on the rotation shafts at both ends of the second worms 51. The fourth support plates are all fixedly provided inside the main beam frame 11. A second transmission shaft is fixedly provided between the two second worms 51. One end of one second worm 51 is fixedly connected to the output end of the motor 52. The motor 52 is fixedly provided inside the main beam frame 11. During use, when the hook 15 moves up and down, the motor 52 is started. The output end of the motor 52 drives the second worm 51 to rotate. The two second worms 51 are meshed with the second worm wheels 50, so that the two chain belts 48 rotate, and the rotation directions are opposite. The chain belt 48 drives the second anti-wind cable 46 to move through the limit slider 47. When the hook 15 lifts goods, under the action of the second anti-wind cable 46, the large-amplitude shaking of the hook 15 can be reduced.

[0045] The above embodiments disclose a windproof gantry crane. When the external wind force is large and affects the normal operation of the main beam frame 11, the first electric cylinder 24 is started. The output end of the first electric cylinder 24 drives the first sliding plate 23 to slide inside the first fixed box 20. Two first sliding plates 23 inside the first fixed box 20 drive four clamping blocks 21 to move through the first connecting rod 22, and the moving directions of the two symmetrically arranged clamping blocks 21 are opposite. When the two symmetrically arranged clamping blocks 21 are in close contact, the clamping blocks 21 clamp and fix the first windproof cable 16, thereby preliminarily fixing the main beam frame 11. At the same time, the first electric cylinder 24 drives the pushing frame 28 to move through the first rack 33. The pushing frame 28 drives the driving slide rod 29 to slide inside the fixed pipe. The driving slide rod 29 drives the second connecting rod 31 and the traction rope 44 to move. The second connecting rod 31 pushes the first rotating plate to move through the mounting plate. The first rotating plate drives the first gear 32 to move through the first internal spline shaft. At the same time, the first rotating plate slides inside the sliding groove at one end of the transmission connecting rod 39 through the first sliding column, so that the transmission connecting rod 39 drives the second sliding plate to slide. The second sliding plate drives the second gear 37 to move through the second internal spline shaft. When the output end of the first electric cylinder 24 stops moving, the first gear 32 meshes with the first rack 33, and the second gear 37 disengages from the second rack 38. Through the self-locking property between the first worm gear 35 and the first worm 36, the main beam frame 11 is finally fixed. The traction rope 44 pulls the sliding frame 41 to slide inside the fixed plate 40. When the driving slide rod 29 stops moving, the support plate 42 is in close contact with the ground, thereby providing auxiliary support for the main beam frame 11.

[0046] When the hook 15 moves up and down, the motor 52 is started. The output end of the motor 52 drives the second worm 51 to rotate. The two second worms 51 mesh with the second worm gears 50, so that the two chain belts 48 rotate, and the rotation directions are opposite. The chain belt 48 drives the second windproof cable 46 to move through the limit slider 47. When the hook 15 lifts the goods, under the action of the second windproof cable 46, the large-amplitude shaking of the hook 15 can be reduced.

[0047] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
