Preferably, the angle between bonded assembly two supports on each described otic placode is 60 °.
Preferably, each described otic placode be arranged on the described respective side edge of crossing bridging beam the middle position directly over.
Preferably, the above-mentioned bridging beam of crossing is spliced by two straight beam b and two halves shaped as frame beam a.
In addition, the utility model also provides a kind of tower crane, it comprises the undersetting assembly of said structure, wherein, the bridging beam of crossing of described undersetting assembly has and four jointings of standard knot bonded assembly and four jointings linking to each other with the frame that climbs, the undersetting of described undersetting assembly links to each other with upper bracket by pivoting support, forms rotating assembly.
Preferably, the cross section of the standard knot of above-mentioned tower crane is more than or equal to 5.0m * 5.0m and be less than or equal to 6.0m * 6.0m.
More preferably, the cross section of the standard knot of above-mentioned tower crane is 5.5m * 5.5m.
Undersetting unit construction of the present utility model is simple, and is stressed clear and definite, weight saving, and manufacturing cost has been saved in convenient processing.Undersetting assembly of the present utility model is particluarly suitable for using on the ultra-large type tower crane.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.With reference to figure, the utility model is described in further detail below.
Description of drawings
Constitute this specification sheets a part, be used for further understanding accompanying drawing of the present utility model and show preferred embodiment of the present utility model, and be used for illustrating principle of the present utility model with specification sheets.Among the figure:
Fig. 1 shows the scheme drawing that is installed on tower crane according to undersetting assembly of the present utility model;
Fig. 2 shows the structural representation according to the undersetting assembly of the utility model preferred embodiment; And
Fig. 3 shows the birds-eye view of undersetting assembly shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 1 shows the scheme drawing that is installed on tower crane according to undersetting assembly of the present utility model, and Fig. 2 shows the structural representation according to the undersetting assembly of the utility model preferred embodiment, and Fig. 3 shows the birds-eye view of undersetting assembly shown in Figure 1.In conjunction with referring to figs. 1 through Fig. 3, the undersetting 151 of undersetting assembly 150 links to each other with upper bracket 110 by pivoting support 130, form rotating assembly, the bridging beam 155 of crossing of undersetting assembly 150 has eight jointings 156,157, wherein inner four jointings 157 link to each other with standard knot 190, and outside four jointings 156 link to each other with the frame 170 that climbs.
In this preferred embodiment, undersetting assembly 150 comprises undersetting 151, crosses bridging beam 155 and strut 153.
Wherein, as shown in Figure 3, cross bridging beam 155 and be square substantially, undersetting 151 assumes diamond in shape substantially.
Four edges and corners of undersetting 151 are welded with otic placode 152, and otic placode 152 was positioned at the middle position of each side of bridging beam 155, and are parallel to this side.
Be connected with two struts 153 on each otic placode 152, the other end of each strut 153 was connected to two bights of bridging beam 155, and the angle between two struts 153 is about 60 °.
During work, the head load of whole tower machine (mainly being vertical power, moment of torsion and moment of flexure) passes to eight struts 153 by the otic placode 152 of undersetting assembly 150, passes to bridging beam 155 downwards, arrives standard knot 190 again, and is stressed clear and definite.
