Abstract
The utility model provides a kind of fractionation crane span structure, comprises girder and end carriage, and end carriage is vertically set on the two ends of girder, and described end carriage is segmentation structure, between each section, by detouchable connecting device, connects, and the interlude of end carriage is fixed on the two ends of girder; Described connecting device is butt flange or connecting board structure; Described end carriage can be connected on the interlude at girder two ends after splitting.The utility model can reduce the width of girder by the fractionation of girder and end carriage, realizes a plurality of girder one car transportations, saves traffic cost, can meet large-tonnage, the situation of low complete machine height simultaneously; In addition, because girder is continuous in whole span, be conducive to orbital arrangement, easily realize the limit size that suspension hook is less.
Description
Technical field
The utility model relates to a kind of novel fractionation crane span structure, belongs to hoisting crane technical field.
Background technology
Compared with the girder of large-tonnage crane in bridge type and end carriage, adopt integral solder (its structure as shown in Figure 1), because width is larger, impact transportation, has increased traffic cost more.Conventional splits girder and end carriage at girder across end, although solution transportation problem, but when running into tonnage compared with large and situation that complete machine limiting altitude is lower, due to large across end shear, stressed complexity, belong to plane of weakness, thereby the poor safety performance after splitting, so this kind of fractionation mode realizes difficulty, because easily causing cart, end carriage deflection gnaws rail simultaneously, so require connection between girder and carriage to have very high positioning precision, also increased fractionation difficulty.
Summary of the invention
Technical problem to be solved in the utility model is the defect existing for prior art, and a kind of fractionation crane span structure of being convenient to make, conveniently transport, meet simultaneously big elevating capacity, low complete machine limiting altitude is provided.
For solving this technical matters, the utility model provides a kind of fractionation crane span structure, comprises girder and end carriage, end carriage is vertically set on the two ends of girder, described end carriage is segmentation structure, between each section, by detouchable connecting device, connects, and the interlude of end carriage is fixed on the two ends of girder.
Described connecting device is butt flange or connecting board structure.
Described end carriage can be connected on the interlude at girder two ends after splitting.
Beneficial effect: the utility model can reduce the width of girder by the fractionation of girder and end carriage, realizes a plurality of girder one car transportations, saves traffic cost, can meet large-tonnage, the situation of low complete machine height simultaneously; In addition, because girder is continuous in whole span, be conducive to orbital arrangement, easily realize the limit size that suspension hook is less.
Accompanying drawing explanation
Fig. 1 is the structural representation of girder and end carriage integral solder;
Fig. 2 is structural representation front view of the present utility model;
Fig. 3 is structural representation birds-eye view of the present utility model;
Fig. 4 is structural representation left view of the present utility model;
Fig. 5 is the structural representation after the utility model splits.
In figure: 1 girder, 2 end carriages, 3 connecting devices.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 2 shows that structural representation front view of the present utility model.
Figure 3 shows that structural representation birds-eye view of the present utility model.
Figure 4 shows that structural representation left view of the present utility model.
The utility model comprises girder 1 and end carriage 2, and end carriage 2 is vertically set on the two ends of girder 1.
Described end carriage 2 is segmentation structure, between each section, by detouchable connecting device 3, connects.
The interlude of end carriage 2 is fixed on the two ends of girder 1.
Described connecting device 3 is butt flange or connecting board structure.
Figure 5 shows that the structural representation after the utility model splits.
After splitting, described end carriage 2 can be connected on the interlude at girder 1 two ends.
The utility model can reduce the width of girder by the fractionation of girder and end carriage, realizes a plurality of girder one car transportations, saves traffic cost, can meet large-tonnage, the situation of low complete machine height simultaneously; In addition, because girder is continuous in whole span, be conducive to orbital arrangement, easily realize the limit size that suspension hook is less.
The above-mentioned embodiment of the utility model, just casehistory, is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
