Abstract
The utility model discloses a miniature DC (Direct Current) hoisting machine which comprises a housing, wherein a motor, a load self-braking device, a speed reducer and a winding drum are arranged in the housing; the speed reducer is in transmission connected with a winding drum shaft in the winding drum; the motor is a DC motor; the load self-breaking device is connected with the output shaft of the motor and comprises a driving disc, a two-way cam, a friction disc, a friction plate, a braking seat and a clutch reed; the driving disc is in transmission connected with the output shaft; the two-way cam is in transmission connected with a transmission shaft; the friction disc is connected with the friction plate into a whole; the transmission shaft is sleeved with the friction plate and the clutch reed; and the friction disc and the friction plate are separated from the braking seat through the clutch reed. Through the adoption of the DC motor, the application range of the hoisting machine is enlarged, for example, the hoisting machine can be used on a truck which only has a DC supply. Therefore, the hoisting machine has a wide market prospect in nowadays society with increasing labor cost.
Description
Technical field
The utility model relates to a kind of lifting weight-lifting equipment, particularly a kind of minisize dc gig.
Background technology
Gig is a kind of general lifting weight-lifting equipment that uses, and occurs on market and the data and the gig report mainly is the usefulness alternating current as propulsion source, is divided into industrial and two kinds of family expenses; Industrial is the three-phase gig, and mostly its structural shape is to adopt phase asynchronous taper braking motor, reel, the coaxial in turn connection of retarder; Family expenses be single-phase gig, mostly its structural shape is to adopt single-phase asynchronous side magnetic braking motor, retarder, the coaxial in turn connection of reel.Because existing gig can only be satisfied with the occasion that source of AC is arranged, and just powerless for the occasion of having only direct supply.
Summary of the invention
The utility model has overcome the deficiency that prior art exists, and provides a kind of simple in structure, safe in utilization, is suitable for the minisize dc gig of direct supply occasion.
For achieving the above object, the utility model adopts following technical scheme: a kind of minisize dc gig, include housing, be provided with motor in the housing, retarder and reel, drum shaft in described retarder and the reel is in transmission connection, described motor is a DC machine, the output shaft of described motor is connected with load self-control device, described load self-control device is in transmission connection by transmission shaft and retarder, described load self-control device includes dial, bidirectional cam, friction disc, friction lining, Brake Block, the clutch reed, described dial and output shaft are in transmission connection, described bidirectional cam and transmission shaft are in transmission connection, described friction disc is connected with the friction lining one, and described friction disc and clutch reed are actively socketed on the cylindrical of transmission shaft, and described clutch reed breaks away from Brake Block with friction disc and friction lining.
The utility model can be directly be input to the corresponding both positive and negative polarity of DC machine with the both positive and negative polarity of direct supply, and DC machine produces power, through load self-control device and retarder, at last transmission of power is given reel and weight is promoted.Described load self-control device has only when motor is static, the weight that is suspended on the reel descends, the drive drum shaft is rotated, pass through retarder, power is passed to transmission shaft, bidirectional cam is rotated, thereby promote friction disc and friction lining, friction lining is compressed and Brake Block, hindered the rotation of bidirectional cam, cause transmission shaft, retarder, drum shaft also to remain static, reel can't rotate, weight also just stops to have descended, thereby plays the effect of braking, has improved the safety of operation coefficient of machine greatly.
The beneficial effects of the utility model are, owing to selected DC machine for use, have enlarged the use occasion of gig, and such as using having only on the goods carrying vehicle of direct supply, the current society in that labor cost increases day by day has vast market prospect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is the structural representation of the utility model embodiment;
1. housings among the figure, 2. motor, 21. output shafts, 3. retarder, 4. reel, 41. drum shaft, 5. load self-control device, 51. dials, 52. bidirectional cams, 53. friction discs, 54. friction linings, 55. Brake Blocks, 56. clutch reed, 6. transmission shafts.
The specific embodiment
With reference to accompanying drawing, a kind of minisize dc gig, include housing 1, be provided with motor 2 in the housing 1, retarder 3 and reel 4, drum shaft 41 in described retarder 3 and the reel 4 is in transmission connection, described motor 2 is a DC machine, the output shaft 21 of described motor 2 is connected with load self-control device 5, described load self-control device 5 is in transmission connection by transmission shaft 6 and retarder 3, described load self-control device 5 includes dial 51, bidirectional cam 52, friction disc 53, friction lining 54, Brake Block 55, clutch reed 56, described dial 51 is in transmission connection with output shaft 21, described bidirectional cam 52 is in transmission connection with transmission shaft 6, described friction disc 53 is connected with friction lining 54 one, described friction disc 53 and clutch reed 56 are actively socketed on the cylindrical of transmission shaft 6, and described clutch reed 56 breaks away from Brake Block 55 with friction disc 53 and friction lining 54.
Concrete principle of work of the present utility model is: the both positive and negative polarity of direct supply is input to motor 2 corresponding both positive and negative polarities, this moment motor 2 output shaft 21 high speed rotating, the dial 51 that is in transmission connection with output shaft 21 also rotates synchronously, drive bidirectional cam 52 and friction disc 53 rotations simultaneously, and with transmission of power transmission shaft 6, slow down through retarder 3, drum shaft 41 is slowly run, drive reel 4 and rotate, thereby weight is promoted; If the both positive and negative polarity transposing of direct supply is input to motor 2 corresponding both positive and negative polarities, this moment motor 2 output shaft 21 reverse high speed rotating, the dial 51 that is in transmission connection with output shaft 21 also synchronous backward rotates, drive bidirectional cam 52 and friction disc 53 backward rotation simultaneously, and with transmission of power transmission shaft 6, slow down through retarder 3, drum shaft 41 low-speed reverse are rotated, drive reel 4 backward rotation, thereby weight is transferred; When motor 2 stops, the weight that is suspended on the reel 4 descends, driving drum shaft 41 rotates, by retarder 3, power is passed to transmission shaft 6, bidirectional cam 52 is rotated, thereby promote friction disc 53 and friction lining 54, friction lining 54 is compressed and Brake Block 55, hindered the rotation of bidirectional cam 52, cause transmission shaft 6, retarder 3, drum shaft 41 also to remain static, reel 4 can't rotate, weight also just stops to have descended, thereby plays the effect of braking, has improved the safety of operation coefficient of machine greatly.
