Description
Technical field
The utility model relates to a kind of crane carriage, is mainly adapted to the hoisting crane of bridge-type, gate-type or other similar type.
Background technology
Traditional bridge, gantry crane trolley, comprise the lightweight bridge of imitative import at present, gate-type crane carriage, its hoisting system all needs to adopt gear case speed-changing mechanism, the high speed low torque moment formal transformation of input end is become the low speed and large torque moment form of low speed end, and then drive reel just can complete the work that hoists of hoisting crane, but some defects that gear case has itself intrinsic, there is transmission waste of power large, leakage of oil, noise danger that is large and off-axis broken teeth may, when being used on crane carriage, also cause crane carriage oad larger, dolly deadweight increases, lifting gear case particularly on crane carriage, because it is much bigger more than operation drive torque to promote moment, so the lifting gear case on crane carriage is more much bigger than the negative effect of operation gear case to crane carriage to the negative effect of crane carriage, and promote gear case once breakage, be directly related to safety problem, therefore, remove elevator system gear case on lifting trolley, design a kind of gearless and promote crane carriage to bridge, transfer crane seems particularly important, crane carriage just can be made to avoid above-described harmful effect to greatest extent.
Utility model content
In order to overcome the above-mentioned defect of prior art, the utility model provides a kind of crane carriage, and this crane carriage structure is simple, and easy to use, fault is few, good reliability.
The technical scheme that the utility model adopts: a kind of crane carriage, comprise by a left side, right-hand member beam and two ends respectively with a described left side, the trolley frame that the equalizing bar that right-hand member beam connects is formed, also comprise lifting motor and steel rope winding mechanism, a described left side, right-hand member beam is separately installed with corresponding adhesion wheel/adhesion wheel group and by motor car wheel/by motor car wheel group, described adhesion wheel/adhesion wheel assembly has wheel drive motors, described lifting motor adopts outer rotor permanent magnet motor, described lifting motor is by left, the rigid mount at right two ends is arranged on a described left side, on right-hand member beam, the rigid mount of the rigid mount that described rigid mount adopts polygon to coordinate or rounded engagement, it is polygonal axle mounting hole that the rigid mount that described polygon coordinates is provided with cross-sectional plane, described lifting motor the installation shaft of respective end adopt corresponding polygonized structure and grafting and be fixed on described polygon coordinate rigid mount axle mounting hole in, it is circular axle mounting hole that the rigid mount of described rounded engagement is provided with cross-sectional plane, described lifting motor adopts cylindrical structural in the installation shaft of respective end and is plugged in the axle mounting hole of the rigid mount of described rounded engagement, be fixedly connected with between installation shaft with rigid mount, the outer rotor of described electrical motor is used for lay winding wire ropes, form the reel of described steel rope winding mechanism, described steel rope winding mechanism also comprises the assembly pulley supporting with described steel rope, described assembly pulley is made up of movable pulley and fixed pulley, the quantity of described fixed pulley and the quantity of described movable pulley are respectively one or more, described fixed pulley is arranged on described equalizing bar.
The beneficial effects of the utility model are: due to adopt outer rotor permanent magnet motor particularly low-speed big outer rotor permanent magnet motor as lifting motor, and outer rotor is directly used as the reel of hoisting crane, without the need to arranging gear case, greatly simplifie the structure of crane carriage thus, reduce oad, alleviate the weight of crane carriage, there is not prior art lower tooth roller box broken teeth, the possibility of off-axis, gearbox leakage under the prior art is not deposited yet, reduce noise, avoid the unnecessary energy consumption because gearbox drive and additional weight bring, improve overall safety and reliability.
Due to the cross-sectional plane of axle mounting hole is arranged to polygon, for installing shape, the polygonal main shaft installation portion (axle journal) that size adapts, contact surface between main shaft and main shaft erection support changes polygon cylinder into by the original face of cylinder, therefore main shaft will rotate relative to main shaft erection support and must have the moment being enough to destroy corresponding polygonized structure, this moment is obviously greater than existing circular shaft mounting hole lower friction force moment that need overcome, thus main shaft is enlarged markedly relative to the circumferential resistance to displacement of main shaft erection support, therefore main bearing is made to significantly improve by the ability of moment of torsion or torsional impact.
