In one embodiment, land lateral bracing strut is a pair, and a pair land lateral bracing strut is arranged in the inner side of described crossbeam.Sea lateral bracing strut is a pair, and a pair extra large lateral bracing strut is arranged in the inner side of described crossbeam.Centre link is a pair, and a pair centre link is arranged in the outside of described crossbeam.
In one embodiment, the interior coxostermum of land lateral bracing strut and extra large lateral bracing strut and crossbeam is to muscle.The outer coxostermum of centre link and crossbeam is to muscle.
In one embodiment, land lateral bracing strut is fixed on the position of distance land side end 1/3 on crossbeam.Centre link is fixed on the position of distance land side end 2/3 on crossbeam.Sea lateral bracing strut is fixed on the extra large side end on crossbeam.
In one embodiment, land lateral bracing strut, centre link and extra large lateral bracing strut all has eccentric bushing.
The crossbeam pull bar of the bank crane that the present invention proposes has three row's pull bars, arrange by increasing by row's pull bar, effectively can promote the rigidity of crossbeam when not increasing large beam section height, the super large-scale bank crane with super large castor, super large hoisting capacity has advantage.
Accompanying drawing explanation
The above and other feature of the present invention, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 discloses the construction profile of the crossbeam pull bar of the bank crane according to one embodiment of the invention.
Fig. 2 discloses the Facad structure figure of the crossbeam pull bar of the bank crane according to one embodiment of the invention.
Detailed description of the invention
Shown in figure 1 and Fig. 2, the present invention is intended to the crossbeam pull bar proposing a kind of bank crane, Fig. 1 discloses the construction profile of the crossbeam pull bar of the bank crane according to one embodiment of the invention, and Fig. 2 discloses the Facad structure figure of the crossbeam pull bar of bank crane.This crossbeam pull bar promotes the rigidity of crossbeam by the mode increasing by row's pull bar, but by not increasing the depth of section of crossbeam.
The crossbeam pull bar land lateral bracing strut 102 of this bank crane, centre link 104 and extra large lateral bracing strut 106.One end of land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 is fixed on the top of the ladder frame 202 of bank crane, and the other end is fixed on the crossbeam 204 of bank crane.From the direction of Ce Zhihai side, land on crossbeam, fix land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 successively.Land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 are a pair separately, are arranged in the both sides of crossbeam 204.Shown in figure 2, a pair land lateral bracing strut 102 is arranged in the inner side of crossbeam 204, with coxostermum in crossbeam to muscle.A pair extra large lateral bracing strut 106 is arranged in the inner side of crossbeam 204 equally, also with coxostermum in crossbeam to muscle.A pair centre link 104 is arranged in the outside of crossbeam, with the outer coxostermum of crossbeam to muscle.As shown in Figure 2, be arranged between land lateral bracing strut 102 inside crossbeam and extra large lateral bracing strut 106 and there is out a grade size A, be arranged between the centre link outside crossbeam and there is out a grade size B.Open a grade size B and be greater than out a grade size A, therefore on the direction along large beam width, land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 stagger mutually.Shown in figure 1, land lateral bracing strut 102 is fixed on the position of distance land side end 1/3 on crossbeam 204.Centre link 104 is fixed on the position of distance land side end 2/3 on crossbeam 204.Sea lateral bracing strut 106 is fixed on the extra large side end on crossbeam 204.Land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 are arranged at equal intervals along the length of crossbeam substantially.Composition graphs 1 and Fig. 2, no matter on the length direction or Width of crossbeam, land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 stagger all mutually, therefore in process steeved by crossbeam land lateral bracing strut, can not mutually interfere between centre link and extra large lateral bracing strut.
In one embodiment, land lateral bracing strut 102, centre link 104 and extra large lateral bracing strut 106 all has eccentric bushing.The effect of eccentric bushing is after pull bar assembling, can carry out a certain amount of adjustment as required to pull bar length.
Adopt the design of three row's pull bars, under acquisition and double pull bar design the prerequisite of equal crossbeam rigidity, the depth of section of crossbeam can be reduced to 2 meters, compared with the depth of section of 2.6 meters required by designing with double pull bar, the deadweight of crossbeam body can alleviate 15%, crossbeam wind area can reduce by 17% (deadweight of crossbeam body is not be directly proportional completely to the depth of section of crossbeam to crossbeam wind area, and therefore above-mentioned data obtain according to calculating and actual tests).
So the design of three row's pull bars solves the problem causing crossbeam rigidity to reduce because castor is long, solves because hoisting capacity increases the problem causing crossbeam rigidity to reduce, solves because large beam section increases the large problem of rear wind area.
