Abstract
The utility model discloses a lower support saddle component used for an ultra-large type tower crane. A lower support saddle structure (2) is connected above a transition beam (3); the lower support saddle structure (2) adopts a transitional structure style that the cross section thereof is changed step by step; the lower part of the transition beam (3) is connected with a tower section (4); and the upper part of the lower support saddle structure (2) is connected with a pivoting support (1). The lower support saddle component is convenient in installation and disassembly, low in installation cost and reasonable in stress.
Description
Technical field
The utility model relates to a kind of ultra-large type tower machine, particularly relates to a kind of ultra-large type tower machine undersetting assembly.
Background technology
Original ultra-large type tower machine setting height(from bottom) height, transition portion (following general designation becomes the undersetting assembly) structure is numerous and diverse between tower machine upper structure and the body of the tower joint, the installing/dismounting trouble, erected cost is all higher; Original ultra-large type tower machine undersetting is formed stressed clear and definite inadequately, and the transition change abrupt change of cross-section of power is big, and is on theory of mechanics, unreasonable.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy installation and removal, and erected cost is lower, stressed rational ultra-large type tower machine undersetting assembly.
In order to solve the problems of the technologies described above, the ultra-large type tower machine undersetting assembly that the utility model provides, above the mistake bridging beam, be connected with the undersetting structure, described undersetting structure adopts the cross section progressively to change the transition structure form, the described bridging beam below of crossing is connected with the body of the tower joint, and described undersetting superstructure is connected with pivoting support.
Adopt the ultra-large type tower machine undersetting assembly of technique scheme, adopt the textural association form of undersetting structure+mistake bridging beam, form the undersetting assembly, reduced the undersetting component height, simplified structure, the undersetting structure adopts the cross section progressively to change the transition structure form, solves the transition change abrupt change of cross-section problem of power.Setting height(from bottom) significantly reduces (height that reduces at least 6 meters and the big more reduction of the hoisting moment of tower machine own is obvious more), designs simplification, and the installing/dismounting facility, actv. has been saved cost of installation; Stressed clear and definite, the transition change cross section of power adopts the cross section progressively to change transition, does not have the transition change abrupt change of cross-section problem of power, and is stressed reasonable.
In sum, the utility model is a kind of easy installation and removal, and erected cost is lower, stressed rational ultra-large type tower machine undersetting assembly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure birds-eye view;
Fig. 3 is the utility model running condition scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2 and Fig. 3, cross bridging beam 3 above be connected with undersetting structure 2, undersetting structure 2 adopts cross sections progressively to change the transition structure form, crosses bridging beam 3 belows and saves 4 with body of the tower and be connected, undersetting structure 2 tops are connected with pivoting support 1.
Referring to Fig. 1, Fig. 2 and Fig. 3, adopt undersetting structure 2+ to cross the textural association form of bridging beam 3, form the undersetting assembly, reduced the undersetting component height, simplified structure, undersetting structure adopt the cross section progressively to change the transition structure form, solve the transition change abrupt change of cross-section problem of power.Setting height(from bottom) significantly reduces (height that reduces at least 6 meters and the big more reduction of the hoisting moment of tower machine own is obvious more), designs simplification, and the installing/dismounting facility, actv. has been saved cost of installation; Stressed clear and definite, the transition change cross section of power adopts the cross section progressively to change transition, does not have the transition change abrupt change of cross-section problem of power, and is stressed reasonable, reduces the possibility that quality problems appear in framing member from designing.
Claims (1)
1, a kind of ultra-large type tower machine undersetting assembly, it is characterized in that: be connected with undersetting structure (2) in the top of crossing bridging beam (3), described undersetting structure (2) adopts the cross section progressively to change the transition structure form, described bridging beam (3) below of crossing is connected with body of the tower joint (4), and described undersetting structure (2) top is connected with pivoting support (1).
