Abstract
The utility model discloses a travelling mechanism of a crane trolley. The travelling mechanism comprises a frame (1), a compensating shaft (2), wheels arranged on the frame (1) and a three-in-one decelerating motor (3), wherein the three-in-one decelerating motor (3) is connected with the frame (1) through a decelerator support (4); one end of a main shaft of the three-in-one decelerating motor (3) is connected with the left wheel (5), and the other end of the main shaft is connected with one end of the compensating shaft (2) through a spline housing coupling A (6); and the other end of the compensating shaft (2) is connected with the right wheel (8) through a spline housing coupling B (7). The travelling mechanism has the advantages of simple structure and convenience in maintenance; by adopting the travelling mechanism, the spatial size is greatly reduced, so that the structure is compact; and because parts are reduced, the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of operating mechanism of crane trolley.
Background technology
Existing operating mechanism of crane trolley (like Fig. 1) mainly comprises drg 9, motor 10, retarder 11, wheel and compensating shaft 2; The two ends of motor 10 are connected with retarder 11 with drg 9 respectively; Retarder 11 is connected with an end of compensating shaft 2 through gear coupling 12, and the other end of compensating shaft 2 is connected with wheel; Because drg, motor and retarder are respectively independently parts, in the time of on being installed in vehicle frame, have caused bulk bigger, simultaneously,, make radial dimension bigger because compensating shaft has adopted gear coupling with being connected of wheel.In order to solve the bigger problem of bulk; Many producers adopt three-in-one reducing motor to substitute drg, motor and retarder; But owing to adopted gear coupling, cause interfering between three-in-one reducing motor and the gear coupling, make three-in-one reducing motor to install.
The utility model content
The purpose of the utility model just provides a kind of compact conformation, operating mechanism of crane trolley easy to maintenance.
The purpose of the utility model is to realize through such technical scheme; A kind of operating mechanism of crane trolley; Comprise vehicle frame, compensating shaft and be arranged on the wheel on the vehicle frame; It also comprises three-in-one reducing motor, and said three-in-one reducing motor connects to ground through reducer stent, and main shaft one end of said three-in-one reducing motor is connected with left wheel; The other end is connected with an end of compensating shaft through spline housing coupler A, and the other end of said compensating shaft is connected with right wheel through spline housing coupler B.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to maintenance, adopt it to dwindle bulk greatly, make and simultaneously,, reduced manufacturing cost by compact conformation owing to reduced the part number.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is original operating mechanism of crane trolley structural representation;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 2; A kind of operating mechanism of crane trolley comprises vehicle frame 1, compensating shaft 2 and is arranged on the wheel on the vehicle frame 1 that it also comprises three-in-one reducing motor 3; Said three-in-one reducing motor 3 is connected with vehicle frame 1 through reducer stent 4; Main shaft one end of said three-in-one reducing motor 3 is connected with left wheel 5, and the other end is connected with an end of compensating shaft 2 through spline housing coupler A6, and the other end of said compensating shaft 2 is connected with right wheel 8 through spline housing coupler B7.
In the utility model,, original drg, motor and retarder have been reduced owing to adopted three-in-one reducing motor; Dwindled oad greatly; Simultaneously, adopt the spline housing coupler, solved the phenomenon that original gear coupling and three-in-one reducing motor interfere when mounted.
Claims (1)
1. operating mechanism of crane trolley; Comprise vehicle frame (1), compensating shaft (2) and be arranged on the wheel on the vehicle frame (1); It is characterized in that: further comprising three-in-one reducing motor (3); Said three-in-one reducing motor (3) is connected with vehicle frame (1) through reducer stent (4); Main shaft one end of said three-in-one reducing motor (3) is connected with left wheel (5), and the other end is connected with an end of compensating shaft (2) through spline housing coupler A (6), and the other end of said compensating shaft (2) is connected with right wheel (8) through spline housing coupler B (7).
