Abstract
The utility model relates to a trolley travelling mechanism for a small gate type crane, which comprises a motor, a speed reducer, a driving device, and a lower crossbeam. The utility model is characterized in that the motor and the speed reducer are installed in the lower crossbeam in the form of a straight arrangement, an output shaft of the speed reducer is sheathed with a bevel gear, teeth of the bevel gear are engaged with teeth of a bevel gear which is sheathed on a bridge piece shaft, and teeth of a straight gear which is sheathed on the other end of the bridge piece shaft is engaged with teeth of a straight gear which is sheathed on a driving trolley wheel. The utility model has the advantages of reasonable design; furthermore, the problems of collision, damage, etc. of the exposed motors and speed reducers of the existing trolley travelling mechanisms can be avoided to occur, and operation is safer.
Description
The utility model relates to a kind of transfer crane traveling mechanism of the larger traveller, especially a kind of small-sized transfer crane traveling mechanism of the larger traveller.
At present, in the goods yard, the transfer crane that transports goods that generally uses of dead weight cargo storehouse and places such as processing and manufacturing, operation assembling, unreasonable because of designing, the drive motor in its traveling mechanism of the larger traveller or the outer margin contour of reductor extend, are exposed to outside the cross sill, both taken site space, very easily directly be subjected to the collision of on-the-spot other transportation means again and be damaged, even may jeopardize the personal safety of field man.
The purpose of this utility model is to provide a kind of design more reasonable, uses the small-sized transfer crane traveling mechanism of the larger traveller of safety.
Technical solution of the present utility model is: motor and reductor array are installed in cross sill inside, suit finishing bevel gear cuter on the output shaft of reductor, the tooth of this finishing bevel gear cuter and the tooth engagement that is sleeved on the finishing bevel gear cuter on the axle of passing a bridge, the tooth of the straight gear of suit and the tooth engagement that is sleeved on the straight gear on the adhesion wheel on the axle other end of passing a bridge.
Compared with prior art, the utility model is owing to be installed in the motor and speed reducer array inside of cross sill, both reduced to take on-the-spot space, avoid and prevented the direct impact of on-the-spot other transportation means, improved the safety of using, again rainproof facility needn't be set again when simultaneously, being used for outdoor location.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Referring to Fig. 1, Fig. 2, drive motor 1 and reductor 2 arrays are installed in cross sill 11 inside, suit finishing bevel gear cuter 3 on the output shaft of reductor 2, the tooth of this finishing bevel gear cuter 3 meshes with the tooth that is sleeved on the straight gear 7 on the adhesion wheel 8 with the tooth engagement that is sleeved on the finishing bevel gear cuter 4 on the gap bridge axle 5, the tooth that is sleeved on the straight gear 6 on axle 5 other ends of passing a bridge again.Adhesion wheel axle 9 is fixed on the foot-supporting frame 10, and foot-supporting frame 10 is connected with cross sill 11.
Its working process is: after drive motor 1 energized, driving reductor 2 rotates, finishing bevel gear cuter 3 by suit on reductor 2 output shafts is given transmission of power the finishing bevel gear cuter 4 that is sleeved on the axle 5 of passing a bridge, finishing bevel gear cuter 4 transmissions gap bridge axle 5, gap bridge axle 5 transmission straight gears again 6, straight gear 6 is given the straight gear 7 that is sleeved on the adhesion wheel 8 with transmission of power again, straight gear 7 transmission adhesion wheels 8, thus realize the cart operation.
