The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, Fig. 4, Fig. 7, shown in Figure 10, a kind of crane bridge, be connected in sequence by some minutes crane span structures, constitute and divide a chord member 10 ends of crane span structure to be provided with cavity 70, the opening part of cavity 70 is positioned at the end of chord member 10, another adjacent chord member 20 ends of Pei Heing are provided with cavity 70 and constitute the roofbolt 80 that sleeve cooperates with it, cavity 70 is provided with the overlapping part of roofbolt 80 and limits the registration device that both separate, shown in Figure 13 c, described registration device comprises adapter shaft 100, and adapter shaft 100 connects the connecting bore 12,81 on chord member 10 and the roofbolt 80 simultaneously.
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, chord member 10,20 is welded as a whole by the mode parallel connection that its web 33 is arranged in parallel by two identical I-beam sections 30 in cross section, the upper and lower wing plate 31,32 and the web 33 of two I-beam sections 30 surround cavity 70, the cross section of cavity 70 is an oblong, as Fig. 4, Fig. 5, shown in Figure 6, one section of roofbolt 80 is positioned at adjacent chord member 20 and captive joint, overhangs in the cavity 70 of chord member 20 exterior another section insertion chord members 10 ends.The recess that web 33 outsides of two I-beam sections 30 and upper and lower wing plate 31,32 form is provided with brace panel 50 along the bar length direction of chord member 10,20, and brace panel 50 is provided with U-shaped opening 51 at the place, the end of matching away from chord member 10,20.It is the effect of playing a reinforced rib for the overlapping part at cavity 70 and roofbolt 80 that brace panel 50 is set, and is provided with the U-shaped opening in addition on brace panel 50, is in order to increase the weld length of brace panel 50 and chord member 10, to make the more firm of both combinations.Be provided with the dividing plate 11 perpendicular to the bar length direction in the cavity 70 of chord member 10, dividing plate 11 to the distance of chord member 10 end faces matches in chord member 20 exterior roofbolt 80 length with overhanging.Because two I-beam sections 30 are arranged in parallel, spacing between the upper and lower wing plate 31,32 of the width of roofbolt 80 and I-beam section 30 matches, so the gap must be left in the junction at the upper and lower wing plate 31,32 of two I-beam sections 30, it is to play a sealing process that dividing plate 11 is set, and can stop the rainwater that fallen by the gap or dust etc.
Embodiment two:
As Fig. 7, Fig. 8, shown in Figure 9, chord member 10,20 is welded as a whole by the relative mode parallel connection of its opening by two identical channel-section steels 40 in cross section, the upper and lower wing plate 41,42 and the web 43 of two channel-section steels 40 surround cavity 70, the cross section of cavity 70 is an oblong, as Figure 10, Figure 11, shown in Figure 12, one section of roofbolt 80 is positioned at adjacent chord member 20 and captive joint, overhangs in the cavity 70 of chord member 20 exterior another section insertion chord members 10 ends.Web 43 inboards of two channel-section steels 40 are provided with brace panel 60 along the bar length direction of chord member 10,20, and web 43 is provided with waist shaped hole 431 at itself and brace panel 60 overlapping positions.Because brace panel 60 is provided in a side of the inboard of the web 43 of channel-section steel 40, so be chosen in and offer waist shaped hole 431 on the web 43, its effect also is in order to increase both weld lengths, owing to channel-section steel 40 is that opening is provided with relatively, the width of roofbolt 80 is less than the spacing between the upper and lower wing plate 41,42 of channel-section steel 40 in addition, so very close to each other between the upper and lower wing plate 41,42, just do not need to be provided with as dividing plate mentioned among the embodiment one 11 these parts yet.
As preferred version of the present utility model, the tonnage that will be provided with according to crane bridge, selection is welded as a whole by two identical I-beam sections 30 in cross section the top boom of chord member 10,20 by the mode parallel connection that its web 33 is arranged in parallel, it is the structure of embodiment one, the lower boom of chord member 10,20 is welded as a whole by the relative mode parallel connection of its opening by two identical channel-section steels 40 in cross section, i.e. the structure of embodiment two.The connecting bore 81 that is provided with on connecting bore 12 that is provided with on while adapter shaft 100 perforation chord members 10 and the brace panel 50 and the roofbolt 80, described adapter shaft 100 is a bearing pin, the number of bearing pin is two, adopts two bearing pins to guarantee to connect by failure-free, and it also is feasible being provided with one or more.As shown in figure 13,10, according to the described crane bridge of arbitrary claim among the claim 1-9, it is characterized in that: the head of adapter shaft 100 is provided with groove in its edge, and the block 90 that matches with groove is fixed on the web 43 of brace panel 50 or channel-section steel 40.Be to offer a groove at the head edge place of bearing pin 100 specifically, the bottom land part of groove leans with the edge of block 90, has limited the rotation of bearing pin 100.
In actual production, or the parameter difference that require different according to the tonnage of hoisting crane can be divided hoisting crane the top boom of chord member of crane span structure or the structure that embodiment one or embodiment two are arranged in the lower boom unification.
In sum, the utility model is no matter be the technology that adopts two I-beam sections, 30 welding in parallel of embodiment one, still adopt the technology of two channel-section steels, 40 welding in parallel of embodiment two, what all adopt is the sleeve cooperation of cavity 70 and roofbolt 80, adopt the connection locate mode of male and female pins shaft type to limit both separation then, this mode is all more simple than existing high strength bolt ways of connecting when assembling or dismounting, practicality, and also cost is low.
