The shore bridge is a special crane for containers widely applied to ports and wharfs. On the one hand, owing to shipping industry's rapid development, bank bridge's reach and load-lifting are all bigger and bigger, and then lead to bank bridge's front and back girder cross-section bigger and bigger, and front and back girder is heavier and heavier, leads to the dolly on the bank bridge to stretch out from the position during operation in front and back, and is bigger and bigger to the wheel pressure of pier, and on the other hand, because pier design is according to the target design of seting up defences in a century, pier side investment is huge, and in case the design construction of pier basis is accomplished, the bearing capacity of pier just has been confirmed, can't change the pier basis easily. The wheeling pressure on the shore bridge arranged on the foundation of the quay is therefore very demanding on the quay side, whereby the overall weight needs to be reduced. The conventional shore bridge web uses a flat web, the weight of the web accounts for 60% of the cross section of the beam, the weight is often required to be reduced by reducing the thickness of the web, and the flat web has poor rigidity in the thickness direction, so that the thickness of the web is reduced and angle steel for strengthening rigidity is required to be arranged on the web to limit the width-thickness ratio of the web in the angle steel partition. Although the plate thickness of the web plate can be reduced through the design, the angle steel is increased, and the weight reduction effect of the web plate is not obvious.
A shore container crane according to the utility model will first be described in detail with reference to the accompanying drawings.

Therefore, the bending strength of the specific part of the shore bridge can be improved by using the corrugated web, the bending strength of the corrugated web is better than that of a straight web in the plate thickness direction, under the same buckling resistance condition, a large number of angle steels need to be arranged to limit the width-thickness ratio when the straight web is used, and the width-thickness ratio of the corrugated web can be 2.4 times that of the straight web. Therefore, the weight can be effectively reduced, the strong bending strength can be kept, meanwhile, the beam height can be increased so as to increase the bending rigidity of the beam section, at the moment, the plate thickness of the flange plate can be correspondingly reduced, the stress division of the flange plate and the web plate is clear, the respective performances of the flange plate and the corrugated web plate are exerted to the greatest extent, the weight is effectively reduced, the working hour for installing the angle steel is saved, and the manufacturing efficiency is effectively improved.

Wherein the two second flange plates 410 are symmetrically arranged; two ends of the second corrugated web 420 are fixedly connected to the two second flange plates 410, respectively. In particular, the i-shaped corrugated web can save 20% of steel compared to a straight web at the same strength. Meanwhile, the I-shaped corrugated web structure is light and firm, so that large-span application can be realized, and the I-shaped corrugated web structure can be effectively adapted to platform parts such as the transfer platform 160 and the cabin cover plate platform 170. Thereby further reducing the pressure of the shore bridge on the quay.
As shown in fig. 7, in one embodiment of the present invention, front longerons 210 include: a first truss beam 212, a second truss beam 213, a third corrugated web 215, and a first stiffener 216. The second truss girder 213 and the first truss girder 212 are arranged in parallel, the length of the second truss girder 213 is greater than that of the first truss girder 212, one end of the second truss girder 213 and one end of the first truss girder 212 are in the same horizontal plane, and one end of the second truss girder 213 departing from the same horizontal plane and one end of the first truss girder 212 departing from the same horizontal plane are fixedly connected through a first connecting plate 214; two ends of the third corrugated web 215 are respectively and fixedly connected with one ends of the first truss girder 212 and the second truss girder 213 which are positioned on the same horizontal plane, and the third corrugated web 215 is perpendicular to the first truss girder 212 and the second truss girder 213; the first reinforcing plate 216 is formed in a triangular shape and is fixedly coupled to the first coupling plate 214. Specifically, when it is required to lift a container of 50 tons or less and the girder reach is less than 50 meters, the right trapezoid-shaped front girder 210 may be used. One side of the front girder 210 is formed into a third corrugated web plate 215, when the shore bridge trolley works at the front and rear extension distance positions, the wheel pressure generated to the wharf is large, and the third corrugated web plate 215 has a shear-resistant full section, so that the shear force generated by the trolley wheel pressure can be effectively resisted, and the pressure on the wharf is reduced. Therefore, the pressure on the wharf is effectively reduced while the structural strength is ensured.
As shown in fig. 1 and 8, in one embodiment of the present invention, the front girder 210 includes: a third truss girder 231, a fourth truss girder 232, a fourth corrugated web 233 and a second stiffener plate 236.

Specifically, when a container with a weight of more than 50 tons needs to be lifted and the front extension distance of the girder is more than 50 meters, the bending plates used by the front girder 210 and the rear girder 220 can effectively disperse the wheel pressure generated by the trolley, so that the wheel pressure generated by the trolley is uniformly dispersed on the girder and the door frame. In addition, the fourth corrugated web 233 has a shear-resistant full cross section, and can effectively resist shear force generated by small wheel pressure while maintaining strength, so that pressure on the wharf is reduced. Therefore, the quay crane can lift the container with larger weight, and can effectively reduce the pressure of the trolley wheel pressure on the wharf.
In one embodiment of the utility model, as shown in FIG. 8, a bending plate comprises: a second connecting plate 234 and a third connecting plate 235.

Therefore, the pressure of the small trolley wheel pressure on the wharf is effectively reduced.
In one embodiment of the present invention, the corrugations formed by the surfaces of the first corrugated web 320, the second corrugated web 420, the third corrugated web 215 and the fourth corrugated web 233 are sine-wave shaped or cosine-wave shaped. Particularly, the corrugated web plate with sine waveform or cosine waveform has high stability and strong shearing resistance, and can effectively resist the larger wheel pressure of the trolley, thereby reducing the pressure of the trolley wheel pressure on the wharf while maintaining the strength.
In one embodiment of the present invention, the width to thickness ratio of first corrugated web 320, second corrugated web 420, third corrugated web 215, and fourth corrugated web 233 is less than
Where fy represents the yield strength of the steel structure.
