Abstract
The invention relates to a main girder of a gantry crane. The main girder is formed by two girders with cross sections being of triangular structures jointly. The main girder of the gantry crane comprises a rail, H-shaped steel, inclined web plates, an inner partition plate, a reinforcing angle steel and hot-rolled common channel steel, wherein two waist edges of the girders with cross sections being of triangular structures consist of the inclined web plates, the H-shaped steel with a wide flange is arranged at the position of an upper apex angle, and a triangular chord member architecture formed by the hot-rolled common channel steel is arranged on the lower horizontal plane. The stable girders with cross sections being of triangular structures are novel structures which are neither solid-web type box structures, nor truss type structures, so that the main girder is low in production cost, good in rigidity, high in strength, light in dead weight, and low in power consumption, and the whole machine is good in wind resistance stability.
Description
Technical field
The present invention relates to the shape and structure of main beam of gantry crane, be specifically related to the main beam of gantry crane that a kind of beam that is triangular structure by two cross-sectional planes is formed jointly, also relate to manufacture and the technique of crane girder simultaneously.
Background technology
Hoisting crane is requisite accessory appliances in modern production process, and Ye Shi rationalization produces indispensable production facilities.From the intensity of complete machine, rigidity, stability and safety, bridge girder part is again the topmost key component of hoisting crane.
Be master at the crane girder of international and domestic use mainly with steel flanged beam box-structure and truss structure.Steel flanged beam box-structure simplicity of design, manufacturing process are good, easy to assembly, highly versatile, be beneficial to automatic welding, torsion stiffness is good, but it is from great, and horizontal rigidity is poor, and the inner welding condition of box-shaped is poor, and wind area is large; Truss structure wind area is little, and deadweight is comparatively light, but complex process, when taking a lot of work, be difficult to ensure that the centre of form of each component as prescribed requires assembling, welding deformation is large.Both merits and faultss often can not be accepted or rejected jointly, cause a lot of safety hazard of hoisting crane.
Summary of the invention
Object of the present invention:
For the merits and faults of above-mentioned background technology crane main beam structure, dynamic simulation analysis and Optimal Structure Designing are carried out to existing tonnage box beam and truss girder major part, develop a kind of main beam of gantry crane new structure, to improve the in-use performance of hoisting crane and to reduce safety hazard.
The technical scheme that the present invention is adopted for achieving the above object is:
Design girder is triangular structure by two cross-sectional planes beam is formed, and wherein each cross-sectional plane is that the beam of triangular structure comprises track, H profile steel, skew web plate, reinforcement angle steel, internal partition, the common channel-section steel of hot rolling.Be in the structure of triangular structure beam at cross-sectional plane, on track laying H profile steel, H profile steel bottom is welded with the skew web plate of inclination certain angle, and angle steel is strengthened in two skew web plate medial surface welding, in two skew web plate, cross-sectional plane welds internal partition at a certain distance.Lower horizontal plane is welded to each other by the common channel-section steel of hot rolling, constitutes lower horizontal plane triangle chord member system.Two skew web plate lower edges weld with the common channel-section steel of hot rolling of horizontal surface triangle chord member system and form the beam that cross-sectional plane is triangular structure, and two identical cross-sectional planes are that the beam of triangular structure together constitutes main beam of gantry crane.
Advantage of the present invention:
Cross-sectional plane is that the main beam of gantry crane advantage of triangular structure is obvious: good rigidity, and intensity is high, and from heavy and light, complete machine gross horsepower is little, energy-conservation, and cost is low, and complete machine wind resisting stability is high, safety.

Fig. 1 is the front view of main beam of gantry crane;
Fig. 2 is front view A-A cross-sectional right side cross section projection view;
Fig. 3 is lateral section projection view under front view N-N cross section;
In figure, 1 be track, 2 being H profile steel, 3 being skew web plate for strengthening angle steel, 4,5 be internal partition, 6 be the common channel-section steel of hot rolling, 7 be the common channel-section steel of hot rolling, 8 be the common channel-section steel of hot rolling, 9 be rail pressing plate, 10 for junction steel plate.
Detailed description of the invention
Two identical beams that main beam of gantry crane is triangular structure by cross-sectional plane are formed jointly, see Fig. 1, Fig. 2, cross-sectional plane is that two skew web plate 4 medial surfaces of triangular structure beam strengthen angle steel 3 according to designed distance longitudinal measure, the angle that two skew web plate 4 tilt certain forms triangle inner chamber, the cross-sectional plane of inner chamber is placed internal partition 5, two waist limits of internal partition 5 is contacted with two skew web plate 4 medial surfaces and firmly welds.On two skew web plate 4, drift angle welds with H profile steel 2 bottom surface, plane welded rails pressing plate 9 on request in H profile steel 2, and track 1 is laid plane in H profile steel 2 and fastened track 1 with rail pressing plate 9.
See Fig. 2, Fig. 3, cross-sectional plane is leg-of-mutton lower horizontal plane is triangle chord member architecture, the common channel-section steel 6 of the hot rolling that two open slots are relative connects and welds as cross-sectional plane is the rod member of rectangular configuration with the middle junction steel plate 10 placed, the upper plane of the two rectangular configuration rod members be welded is welded with two skew web plate 4 lower edge levels respectively, triangle chord member architecture is jointly formed by the common channel-section steel of vertical bar hot rolling 7 and the common channel-section steel 8 of brace hot rolling in the middle of two rectangular configuration rod members, the main beam of gantry crane that the beam that to define by two cross-sectional planes be triangular structure is formed jointly.
