Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to windproof gantry crane equipment and a use method thereof. Background Art

[0002] Gantry crane is a variation of bridge crane, also called gantry crane, which is mainly used for loading and unloading operations of outdoor cargo yards, material yards and bulk cargo. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. When common gantry cranes are used for a long time in outdoor places with strong wind, the external wind will blow on the main beam frame at the top of the crane for a long time, and when driving the cargo loading and unloading to move against the wind, the wind blowing on the main beam frame will be stronger, causing the crane to consume a lot of kinetic energy when moving, and when the wind is strong, the overall center of gravity of the crane will shift. In some areas prone to wind damage, when not in 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 rollover, but also has safety hazards that cause personal safety and economic losses.

[0003] The existing authorization announcement number is: CN114890303B, which discloses a windproof door-type lifting device for large-span lifting. Through the cooperation of the windproof cable with the locking mechanism and the positioning mechanism, it is convenient to effectively improve the wind resistance of the door-type lifting device on windy days, and at the same time improve the anti-slip effect of the door-type lifting device on windy days, so as to facilitate the door-type lifting device to play a role of multiple limit locking. Among them, the positioning mechanism includes a movable strip, and the inner bottom surface of the positioning box is equidistantly provided with a plurality of through holes in cooperation with the limit plug block; the top surface of the positioning strip is equidistantly provided with a plurality of positioning holes in cooperation with the limit plug block; it is convenient to The lifting device has the function of limiting and fixing, and at the same time prolongs the service life of the braking mechanism inside the moving seat. However, when the above-mentioned lifting equipment is in use, since the limit plugs are arranged in an array with equal spacing, and the limit plugs move with the lifting device, while the positioning port does not move, the staff needs to constantly adjust the position of the lifting device during use so that the limit plug can be used only after it is aligned with the positioning port. Since the positioning mechanism and the locking mechanism are arranged in a linkage state, the locking mechanism cannot be used when the limit plug is not aligned with the positioning port, which makes it inconvenient to quickly protect the lifting device in some emergency situations.
