Wind-resisting and overturning-preventing device for quay cranes and quay crane unit

Abstract

The invention discloses a wind-resisting and overturning-preventing device for quay cranes and a quay crane unit. The wind-resisting and overturning-preventing device comprises a concave component anda convex component, the concave component and the convex component are clamped, the concave component is arranged at the end of a cross beam of a first quay crane, and the convex component is arranged at the end of a cross beam of a second quay crane, so that the first quay crane is in butt joint with the second quay crane; the concave component / convex component is of a box body structure formedby adopting and welding a plurality of steel plates; two or more quay cranes in the quay crane unit are provided with the wind-resisting and overturning-preventing device for the quay cranes and are connected through the wind-resisting and overturning-preventing device for the quay cranes. The wind-resisting and overturning-preventing device for the quay cranes and the quay crane unit can replaceor partially replace a wind-resisting inhaul cable and a balance weight, the storm wind-resisting overturn-preventing capacity of the quay cranes is improved, the practicability of equipment is improved, and the new construction or transformation cost of a wharf is reduced.

Description

technical field [0001] The invention relates to the field of quay cranes, in particular to a wind-resistant and overturning device for quay cranes and a quay crane unit, which are mainly used for wharves without anti-overturning embedded parts or with insufficient embedded parts. Background technique [0002] In the design of the quay bridge, the general wind resistance and anti-overturning device is more important; in the prior art, the factory protects the quay bridge by means of windproof cables and adding counterweights; when using the windproof cable method, manual assembly is required every time it is used And disassembly, which affects the improvement of the automation rate; when the method of increasing the counterweight is adopted, although the stability requirement can be met without modifying the wharf, the efficiency is low, and it is often necessary to increase hundreds of tons or even hundreds of tons to realize the quay bridge. Anti-overturning, and secondly, ...

[0002] In the design of the quay bridge, the general wind resistance and anti-overturning device is more important; in the prior art, the factory protects the quay bridge by means of windproof cables and adding counterweights; when using the windproof cable method, manual assembly is required every time it is used And disassembly, which affects the improvement of the automation rate; when the method of increasing the counterweight is adopted, although the stability requirement can be met without modifying the wharf, the efficiency is low, and it is often necessary to increase hundreds of tons or even hundreds of tons to realize the quay bridge. Anti-overturning, and secondly, the counterweight itself is a big test for the carrying capacity of the quay bridge itself and the wharf; these measures for wind resistance and overturning will eventually be docked and transferred to the wharf and have a greater impact on it

[0003] With the large-scale quay crane and the increasing wind force in the natural environment, the increase in the uplift force brought about by the increase in wind force and the increase in the weight of the equipment itself put forward more stringent requirements for the original wharf bearing capacity and wind-resistant embedded parts. , In addition, the matching windproof embedded parts of the old wharf and the reconstruction equipment, and the windproof cable capacity of the newly added equipment do not match. The design of the
