Technical field
The utility model relates to a kind of hoisting crane, relates in particular to a kind of crane span structure of crane in bridge type.
Background technology
As everyone knows, crane in bridge type generally comprises: electric apparatus, crane span structure, dolly, traveling mechanism of the larger traveller etc.Wherein, the keystone configuration of crane span structure is girder and end carriage.
Join shown in Figure 1ly, in the prior art, the set of wheels 30 of the crane span structure 100 of crane in bridge type is arranged near the end at end carriage 10 two ends, and vertically is installed on the longitudinal extension direction of end carriage, is installed in like arrow direction among Fig. 1 in the accepting groove 20 of end carriage 10.Bearing seat (not shown) uses bolt that bearing seat is fixed in the screw 401 through the flange 40 on accepting groove 20 limits, thus fixing set of wheels 30.
So when the set of wheels of assembling crane span structure, need crane span structure be lifted.Because the weight of whole crane in bridge type is huge, reaches tens tons usually.So in manufacturing process, particularly in the maintenance process after installation, needing to use the jack crane in bridge type that weight is huge to lift could the change of wheels group.So just exist set of wheels to change the problem of difficulty.Simultaneously, the step of change of wheels group is also comparatively loaded down with trivial details, and human cost is bigger, also has certain danger.
Set of wheels is mainly through being bolted to the end, two ends of end carriage.Because the total weight of crane in bridge type is very big, generally all tens tons.Shown in only rely on the bolted set of wheels may cause crane in bridge type after long-time the use because bolt aging or get rusty, thereby cause set of wheels to remove original fixed position, thereby produce dangerous.
Simultaneously because the end carriage of general crane span structure all be a hollow structure, so its shear resistance ability a little less than, thereby cause the integral rigidity deficiency of end carriage, may have certain potential safety hazard.
In view of this, be necessary the crane span structure of crane in bridge type is improved, to address the above problem.
The utility model content
The purpose of the utility model is to provide a kind of crane span structure of crane in bridge type; It can easy Overhead Crane Bridge the set of wheels of end, end carriage two ends change; Reduce the human cost of change of wheels group; Danger when reducing maintainer's change of wheels group has to fix set of wheels effectively simultaneously, the integral rigidity of the end carriage of the crane span structure of raising crane in bridge type and the safety of crane in bridge type.
For realizing above-mentioned utility model purpose, the utility model provides a kind of crane span structure of crane in bridge type, and it comprises
Some set of wheels, and
End carriage, end, said end carriage two ends respectively is provided with an accepting groove, in order to set of wheels to be installed;
The installation direction of said set of wheels and accepting groove is identical with the longitudinal extension direction of said end carriage, and end, said end carriage two ends also is provided with some locating pieces.
As the further improvement of the utility model, the opening direction of said accepting groove is identical with the longitudinal extension direction of said end carriage.
As the further improvement of the utility model, said accepting groove is arranged at the end, two ends of end carriage.
As the further improvement of the utility model, said locating piece is arranged on the web of end, said end carriage two ends.
As the further improvement of the utility model, said locating piece is periphery and is arranged at the edge of said accepting groove.
As the further improvement of the utility model, any end end of said end carriage is provided with two locating pieces at least.
Compared with prior art; The beneficial effect of the utility model is: the installation direction through set of wheels and accepting groove is identical with the longitudinal extension direction of said end carriage; And the such structure of locating piece is set in the end, end carriage two ends of crane span structure; The set of wheels of end, end carriage two ends that can easy Overhead Crane Bridge is changed, and reduces the human cost of change of wheels group, the danger when reducing maintainer's change of wheels group; Simultaneously can prevent that also the set of wheels in the accepting groove from skidding off, and improve the integral rigidity of end carriage and the safety of crane in bridge type.
