Abstract
The utility model discloses a lifting device of a fume hood, and the lifting device comprises a motor, a reduction gear, a clutch, a double-groove driving pulley, a driven pulley and steel wire ropes; a rotating shaft of the motor is connected with the input shaft of the reduction gear; one end of the clutch is connected with the output shaft of the reduction gear, the other end of the clutch is connected with the rotating shaft of the double-groove driving pulley; the steel wire ropes are arranged on the double-groove driving pulley and driven pulley. When in electric operation, the clutch is always at the closed state and transmits torque; the motor drives the double-groove driving pulley through the reduction gear and the clutch; the double-groove driving pulley drives the steel wire ropes to move, so as to lift a fume hood door; when in manual operation, the clutch is always at the separating state and does not transmit torque. Therefore, the torque of the reduction gear does not need to be overcome when the fume hood door is lifted manually, so that the manual operation is convenient.
Description
Technical field
The utility model relates to vent cabinet technical field, relates in particular to a kind of lifting gear of vent cabinet, and the vent cabinet of applying this lifting gear.
Background technology
At present, the lifting gear of vent cabinet is comprised of the motor with reductor, double flute driving pulley, follow-up pulley and wire rope, in the course of the work, motor energising drives double flute driving pulley to rotate, double flute driving pulley by and wire rope between frictional force drive wire rope to move, thereby realize moving up and down of vent cabinet door.But, because the motor with reductor is directly connected with double flute driving pulley, when the lifting of vent cabinet door is manually carried out in power-off, need to overcome the moment of torsion that reductor reversion produces, manual operation is very inconvenient.
Utility model content
The problem existing for prior art, the purpose of this utility model is to have proposed a kind of vent cabinet and lifting gear, and when the lifting of vent cabinet door is manually carried out in power-off, without the moment of torsion that overcomes reductor generation, manual operation is very convenient.
For reaching this object, the utility model by the following technical solutions:
A kind of lifting gear of vent cabinet, comprise motor, reductor, clutch, double flute driving pulley, follow-up pulley and wire rope, the rotating shaft of motor is connected with the power shaft of reductor, one end of clutch is connected with the output shaft of reductor, the other end of clutch is connected with the rotating shaft of double flute driving pulley, and wire rope is located on double flute active slip and follow-up pulley.
A vent cabinet, comprises vent cabinet door, also comprises the lifting gear of above-mentioned vent cabinet, and wherein wire rope is connected with vent cabinet door.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
In the utility model, one end of clutch is connected with the output shaft of reductor, and the other end of clutch is connected with the rotating shaft of double flute driving pulley; When electric operating, clutch is all the time in closure state, clutch transmission torque, and motor is by reductor and further by clutch, drive double flute driving pulley to rotate, double flute driving pulley drives wire rope motion, thereby realize the elevating movement of vent cabinet door, when manual operation, clutch is all the time in released state, clutch is transmitting torque not, therefore, while manually carrying out the lifting of vent cabinet door, without the moment of torsion that overcomes reductor, facilitate manual operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lifting gear of a kind of vent cabinet of proposing of the utility model embodiment.
The specific embodiment
The structural representation of the lifting gear of a kind of vent cabinet proposing for the utility model embodiment as shown in Figure 1.
With reference to Fig. 1, the lifting gear of a kind of vent cabinet that the utility model embodiment proposes, comprise motor 1, reductor 2, clutch 3, double flute driving pulley 4, follow-up pulley and wire rope, the rotating shaft of motor 1 is connected with the power shaft of reductor 2, one end of clutch 3 is connected with the output shaft of reductor 2, the other end of clutch 3 is connected with the rotating shaft of double flute driving pulley 4, and wire rope is located on double flute active slip 4 and follow-up pulley.
In above-described embodiment, one end of clutch is connected with the output shaft of reductor, and the other end of clutch is connected with the rotating shaft of double flute driving pulley, and its operating principle is as follows:
When electric operating, clutch is all the time in closure state, clutch transmission torque, and motor is by reductor and further by clutch, drive double flute driving pulley to rotate, double flute driving pulley drives wire rope motion, thereby realizes the elevating movement of vent cabinet door;
When manual operation, clutch is all the time in released state, and clutch is transmitting torque not, therefore, while manually carrying out the lifting of vent cabinet door, without the moment of torsion that overcomes reductor, facilitates manual operation.
The utility model has also proposed a kind of vent cabinet, comprises vent cabinet door, also comprises the lifting gear of above-mentioned vent cabinet, and wherein wire rope is connected with vent cabinet door, by motion the moving up and down with drive vent cabinet door of wire rope in lifting gear.
The beneficial effect of the lifting gear based on above-mentioned vent cabinet, the vent cabinet of applying this lifting gear also has above-mentioned beneficial effect.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
