Description
Technical field
The utility model relates to a kind of mono beam overhead crane large vehicle walking device.
Background technology
The box end carriage of existing mono beam overhead crane large vehicle walking device adopts the U-lag beam usually and places the flange plate of end opening to be welded, hoisting crane for different size, because the size in different U-shaped cross sections is difficult to unified, often need to adopt different moulds to form by the steel plate compacting, thereby caused complex manufacturing, the drawback that tooling cost is higher.
And for the electric single-beam weight-lifting equipment, its large vehicle walking Design of device is very important, therefore is necessary the structure of existing large vehicle walking device is improved, and uses needs thereby satisfy.
The utility model content
In view of this, the utility model provides a kind of mono beam overhead crane large vehicle walking device, helps production and processing and cost-cutting, and the while can guarantee working well of equipment and use safely.
The purpose of this utility model provides a kind of mono beam overhead crane large vehicle walking device, comprise the box girder, the two ends of described box girder are connected with the box end carriage respectively, the both ends of described box end carriage are symmetrically arranged with adhesion wheel and driven wheel, also be provided with the driver train that is connected with adhesion wheel on the described box end carriage, described driver train comprises drive motor and retarder, described box end carriage comprise a pair of web and on, lower cover, described web is channel steel shape, on described, the cross-sectional plane of lower cover is " worker " font, on the described web, following two ends are embedded respectively and are arranged on, between " worker " font fluting of lower cover.
Further, described web adopts the mode of assembly welding firmly to be connected with cover plate;
Further, described box girder is horizontally installed on the top of box end carriage and has the initiative between wheel and the driven wheel;
Further, described box girder is near the adhesion wheel setting;
Further, described retarder is fixedly installed on the inboard of box end carriage, and the output shaft of described retarder is connected with adhesion wheel by coupler;
Further, described retarder is a rotation axis train retarder;
Further, the position that is connected with adhesion wheel, driven wheel, the inboard of described web is provided with the axle hole stiffening plate.
The beneficial effects of the utility model are:
1. the utility model has improved the structure of box end carriage, web and cross section that employing is channel steel shape are " worker " the upper and lower cover plate of font forms, by web being embedded between the I-groove of cover plate up and down, can improve the bulk strength of end carriage, the forming process of web is simple simultaneously, productive costs reduces, and the inertia of end carriage is apart from also being improved significantly;
2. in the utility model, the box girder is horizontally installed on the top of box end carriage and has the initiative between wheel and the driven wheel, bears vertical pressure by end carriage, helps increasing the strength and stiffness of end carriage;
3. adopt the mode of the main body of box girder near the adhesion wheel setting, the wheel load that makes adhesion wheel is greater than driven wheel, thereby solved the wheel wheel face not on same plane or track unsettled problem of contingent driving wheel when being uneven, guaranteed the safe operation of hoisting crane;
4. adopt reinforcement to handle, can reduce the extrusion stress of wheel shaft opposite end web, improve the moment of inertia of end carriage.
Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification sheets and claims.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
