Abstract
The utility model relates to a mechanism for coarsely adjusting the span of a gantry crane. The mechanism comprises a main beam connection plate and a supporting leg connection plate, wherein corresponding bolt holes are formed on the main beam connection plate and the supporting leg connection plate; and the main beam connection plate and the supporting leg connection plate are fixedly connected with each other through bolts. The span of the gantry crane is coarsely adjusted by changing the positions of connection holes, so that the gantry crane can meet requirements of different work environments.
Description
Technical field
The utility model relates to freight container lifting appliance technical field, especially a kind of gauntry crane span coarse adjustment mechanism.
Background technology
Along with the fast development of world economy, the loading and unloading capacity of harbour container constantly increases, thereby more and more higher to the requirement of freight container lifting appliance, require its more flexibly, practical more, efficient more.Though track type container gauntry crane before can have been finished most of lifting task, because situation is changeable, requires the span of gauntry crane to adjust at any time, thereby adapt to various working environments better at present.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that existing gauntry crane exists in the above-mentioned background technology, provide a kind of gauntry crane span coarse adjustment mechanism.
The technical scheme that its technical matters that solves the utility model adopts is: comprise girder connecting panel and supporting leg connecting panel, offer mutual cooresponding bolt hole on described girder connecting panel and the supporting leg connecting panel, the girder connecting panel is captiveed joint by bolt passing through bolt hole with the supporting leg connecting panel.
Further, the fixed span value of the bolt hole on girder connecting panel described in the utility model and the supporting leg connecting panel is 100mm, changes the connecting bore position and realizes change interval, reaches the demand that adapts to different basic spans.
The beneficial effects of the utility model are, the utility model offers the bolt hole of fixed span value on girder connecting panel and supporting leg connecting panel, carry out span coarse adjustment to gauntry crane by changing the connecting bore position, can adapt to the demand of different working environments to it.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
