Abstract
The utility model discloses a kind of gantry crane girder adopting U-shaped muscle, comprise the top panel for installation carriage track, top panel parallel beneath is provided with lower shoe, top panel is connected with the web of lower shoe by both sides, some cross walls are provided with in the girder beam body that top panel, lower shoe and web enclose, the inside face of top panel and lower shoe is provided with U-shaped muscle, and the inside face of web is provided with U-shaped muscle and/or L shape flanging gusset.The utility model adopts top panel and web upper inside surface to arrange U-shaped muscle, the local stability of reinforcement plate, U-shaped muscle on lower shoe can balance the position of form center of girder section, show through girder Strength co-mputation, said structure can increase the moment of inertia of girder, reduce the maximum stress of girder, promote the load-carrying capacity of girder.
Description
Technical field
The utility model relates to elevator machinery technical field, is specifically related to a kind of gantry crane girder adopting U-shaped muscle.
Background technology
Gantry crane is as the goliath in shipbuilding yard, and work such as being mainly used in segmental hoisting, standing up, close up is the key equipment building large ship.Along with the development of shipbuilding industry, also more and more higher to the demand of big elevating capacity gantry crane.The girder of gantry crane is the key structure part of hoisting crane, and the quality of its design directly determines performance and the cost of hoisting crane complete machine.
Gantry crane girder will ensure trouble free service, and must arrange longitudinal gusset to guarantee the local stability of plate on upper and lower panel and web, longitudinal gusset generally adopts angle steel or T-steel.Along with the increase of hoisting capacity, girder height is also progressively improving, and hoister in large tonnage girder is generally more than ten meters of height.In order to ensure that gusset has enough rigidity, the specification of gusset is also increasing.Large gusset can cause cross wall perforate excessive, reduces load-carrying capacity, and installation quantity is many, and difficulty of construction increases thereupon.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides one both to meet load bearing requirements, again the gantry crane girder of the employing U-shaped muscle of constructability.
For achieving the above object, the technical solution of the utility model is a kind of gantry crane girder adopting U-shaped muscle, it is characterized in that, comprise the top panel for installation carriage track, described top panel parallel beneath is provided with lower shoe, described top panel is connected with the web of lower shoe by both sides, some cross walls are provided with in the girder beam body that described top panel, lower shoe and web enclose, the inside face of described top panel and lower shoe is provided with U-shaped muscle, and the inside face of described web is provided with U-shaped muscle and/or L shape flanging gusset.
In order to the technique effect of the position of form center of further Optimization Balancing girder section, preferred technical scheme is, the top of described web inside face is provided with U-shaped muscle, and the middle part of described web inside face and bottom are provided with L shape flanging gusset.
Easy to process in order to ensure U-shaped muscle, preferred technical scheme can also be, the cross-sectional plane of described U-shaped muscle is the arc earth overvoltage of open-bottom.
Preferred technical scheme can be, spaced set between described adjacent L shape flanging gusset.
Advantage of the present utility model and beneficial effect are:
The utility model adopts top panel and web upper inside surface to arrange U-shaped muscle, the local stability of reinforcement plate, U-shaped muscle on lower shoe can balance the position of form center of girder section, show through girder Strength co-mputation, said structure can increase the moment of inertia of girder, reduce the maximum stress of girder, promote the load-carrying capacity of girder.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gantry crane girder;
Fig. 2 is the cutaway view along A-A in Fig. 1.
In figure: 1, girder beam body; 2, top panel; 3, lower shoe; 4, web; 5, cross wall; 6, U-shaped muscle; 7, L shape flanging gusset.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, the gantry crane girder of embodiment, comprise the top panel for installation carriage track, top panel 2 parallel beneath is provided with lower shoe 3, top panel 2 is connected with the web of lower shoe 3 by both sides, some cross walls 5 are provided with in the girder beam body 1 that top panel 2, lower shoe 3 and web 4 enclose, the inside face of top panel 2 and lower shoe 3 is provided with U-shaped muscle 6, the top of web 4 inside face is provided with U-shaped muscle 6, and the middle part of web 4 inside face and bottom are provided with L shape flanging gusset 7; The cross-sectional plane of U-shaped muscle 6 is the arc earth overvoltage of open-bottom; Spaced set between adjacent L shape flanging gusset 7.
The two ends of girder beam body are provided with end plates, and the end face of U-shaped muscle and L shape flanging gusset is fixedly connected on end plates or cross wall.
Adopt above-mentioned main beam structure, the excessive technological deficiency causing the corresponding increase of cross wall perforate of gusset because of hoister in large tonnage girder can be avoided.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
