The specific embodiment
Be described in further detail the utility model proposes a kind of mixer elevating mechanism below in conjunction with the drawings and specific embodiments.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that accompanying drawing all adopts very the form of simplifying and all uses non-accurately ratio, only in order to convenient, the purpose of aid illustration the utility model embodiment lucidly.
Please refer to Fig. 1, it is the front view of a kind of mixer elevating mechanism of the utility model embodiment.As shown in Figure 1, described mixer elevating mechanism comprises:
Line slideway 1, bottom support frame 3, footstock 5, crane 6, lifting nut 9, worm type of reduction gearing 10 and screw rod 13;
One end of described line slideway 1 is connected with bottom support frame 3, and the other end is connected with footstock 5;
Described crane 6 is arranged between bottom support frame 3 and the footstock 5, and crane 6 can be along line slideway 1 oscilaltion;
Described lifting nut 9 is fixed on the crane 6;
Described worm type of reduction gearing 10 is installed on the footstock 5;
One end of described screw rod 13 links to each other with the output shaft of worm type of reduction gearing 10, and the other end links to each other with lifting nut 9 on the crane 6.
Concrete, an end of line slideway 1 is connected with bottom support frame 3 by the first flange 2, and the other end is connected with footstock 5 by the second flange 4.For strengthening the structural stability of described mixer elevating mechanism, be provided with bottom bar 7 at bottom support frame 3.Crane 6 is arranged between bottom support frame 3 and the footstock 5, and crane 6 can move up and down along line slideway 1, and rabbling mechanism (comprise and drive motor, transmission mechanism and the agitator that agitator rotates) is installed on the crane 6 by screw.For guaranteeing crane 6 easy motions, between crane 6 and line slideway 1, linear bearing 8 is set.Worm type of reduction gearing 10 is installed on the footstock 5 by worm type of reduction gearing mount pad 12, worm type of reduction gearing mount pad 12 is so that worm type of reduction gearing 10 is installed more firmly, and in worm type of reduction gearing 10 installation and operation processes, play protective action, avoid the parts of worm type of reduction gearing 10 to be subject to the external force damage.One end of screw rod 13 links to each other with the output shaft of worm type of reduction gearing 10 by the shaft coupling (not shown in figure 1), and the other end links to each other with lifting nut 9 by screw thread.Lifting nut 9 is fixed by screws on the crane 6.
Concrete, please also refer to Fig. 3, it is the enlarged diagram of regional B among Fig. 2.As shown in Figure 3, by the fixing lifting nut 9 of screw, an end of screw rod 13 and lifting nut 9 mesh between the internal thread of the external screw thread of screw rod 13 and lifting nut 9 by thread connection on crane 6.
Worm type of reduction gearing 10 is with motor 11 in the present embodiment.Worm type of reduction gearing 10 is translator 11 not also, and its principle is constant, has just changed position and the connected mode of motor.Concrete, in the situation of translator, motor 11 can not be installed on the footstock 5 by mount pad worm type of reduction gearing 10 self, and the output shaft of motor 11 connects by the power shaft of shaft coupling with worm type of reduction gearing 10.
During work, starter motor 11, then the output shaft of worm type of reduction gearing 10 drives screw rod 13 rotations, mesh between the internal thread of the external screw thread of screw rod 13 and lifting nut 9, in the present embodiment, because lifting nut 9 is fixed on the crane 6, can not rotate, therefore lifting nut 9 drive cranes 6 move up and down along line slideway 1, and the rabbling mechanism that is installed on the crane 6 produces elevating movement thereupon.
For fear of the rabbling mechanism and the footstock 5 that in lifting process, are installed on the crane 6, perhaps bump between agitator and the stirring tank body, described mixer elevating mechanism is provided with position-limit mechanism.Please refer to Fig. 2, it is the left view of a kind of mixer elevating mechanism of the utility model embodiment.As shown in Figure 2, described position-limit mechanism comprises travel switch mounting frame 14, upper stroke switch 15, lower stroke switch 16, the upper end of travel switch mounting frame 14 is fixed on the footstock 5 of elevating mechanism (can be corresponding to figure 1), and the lower end is fixed on (can be corresponding to figure 1) on the bottom support frame 3.Upper stroke switch 15 and lower stroke switch 16 are bolted on respectively the up and down two ends of travel switch mounting frame 14, their determining positions the scope that moves up and down of mixer elevating mechanism, the mixer elevating mechanism was out of service when crane 6 rose to the position that upper stroke switch 15 sets, the mixer elevating mechanism was out of service when crane 6 dropped to the position that lower stroke switch 16 sets, the moving range of crane 6 is just between upper stroke switch 15 and lower stroke switch 16, in lifting process, guarantee rabbling mechanism and footstock 5 on the crane 6, perhaps can not bump between agitator and the stirring tank body.
As fully visible, the utility model mixer elevating mechanism drives the rabbling mechanism that is installed on the crane and moves up and down by Mechanical Driven, thereby realizes the elevating function of rabbling mechanism.Described mixer elevating mechanism need not to dispose Hydraulic Station and hydraulic control system, greatly reduced manufacturing cost and the rate of breakdown of equipment, and simple in structure, be easy to install and maintenance, described mixer elevating mechanism also is provided with position-limit mechanism, has further improved the reliability of equipment.
Foregoing description only is the description to the utility model preferred embodiment; it is not any restriction to the utility model scope; any change, modification that the those of ordinary skill in the utility model field is done according to above-mentioned disclosure all belong to the protection domain of claims.
