Description
One, technical field:
The utility model relates to a kind of crane lifting mechanism, particularly a kind of lifting winch with moment limiting protecting function.
Two, background technology:
The engineering winch or the winch that have moment limiting protecting function at present; the structure of moment limiting device and transmission of power and performance element (drop-gear box, reel etc.) is separately independently; the connection unit (such as coupler etc.) that needs transition each other, in this case the complex structure of winch, machine volume is big, weight is big and efficient is also low.Under some specific working environments, as deck crane, the lifting lifting of open ocean and elevator operation, traditional winch or winch are just inapplicable.
Three, summary of the invention:
Goal of the invention of the present utility model provides that a kind of rational in infrastructure volume is little and in light weight and very compact, and live load is big, efficient is high, operate steadily the moment limiting protecting winch that can work under complicated rugged environment.
Moment limiting protecting winch of the present utility model, comprise: support, connecting rod, motor, planetary reduction box, two ends by reel, the moment limiting protector of bracket supports, connect reel the end cap flange, connect the spool spindle of end cap flange, it is characterized in that it also is included in small oil tank outside reel and the end cap flange, regulates bolt, jam nut; Motor is installed in the input end of planetary reduction box, and the input end of planetary reduction box, moment limiting protector are located at the inner chamber of reel.
Moment limiting protecting winch of the present utility model has following advantage:
1. winch can be driven through epicyclic gear box by HM Hydraulic Motor or motor, and the torque power that the epicyclic gear box volume is little, in light weight, efficient is high, transmit is big, and self has brake equipment, steady during the work operation, safety, reliable.
2. winch is equipped with the moment limiting protector; has moment limiting protecting function; the moment limiting protector combines with planetary reduction box and is designed to integral body; the built-in inner chamber that is installed on capstan drum; simple and reasonable and very compact; reduced the oad of complete machine greatly, made, install, use, safeguarded easily simple.
3. the moment limiting device of winch is by the dry type partial metallurgy friction lining transfer torque of compression spring loading; the moment limiting protector is adjusted the size that the pressure of compression spring is adjusted its carry-over moment by regulating bolt; be applicable to the limiting protecting under the different loads grade, make it have wider range of use.
Four, description of drawings:
Fig. 1 is the structure cutaway view of the utility model moment limiting protecting winch.
Fig. 2 is the structure cutaway view Amplified image of this advantageous torque of this practicality limiting protecting winch moment limiting protector.
Five, the specific embodiment:
Structure below in conjunction with description of drawings the utility model moment limiting protecting winch:
The keystone configuration of the utility model moment limiting protecting winch comprises support 1, connecting rod 2, motor 3 (also can adopt HM Hydraulic Motor or), planetary reduction box 4, reel 5, moment limiting protector 6, end cap flange 7, spool spindle 8, small oil tank 9, regulates bolt 10, jam nut 11.Wherein motor 3 is installed in the input end of planetary reduction box 4, and the input end of planetary reduction box 4, moment limiting protector 6 are installed in the inner chamber of reel 5; End cap flange 7 connects reel and spool spindle 8, and reel 5 two ends are by support 1 supporting; Small oil tank 9, adjusting bolt 10, jam nut 11 are outside reel 5 and end cap flange 7.
The moment limiting protector 6 of this winch is made up of base plate 12, gear ring 13, internal friction sheet 14, outside friction disc 15, clamping piston 16, compression spring 17, pressing plate 18; wherein compression spring 17 produces thrust between clamping piston 16 and pressing plate 18; clamping piston 16 compresses internal friction sheet 14 and outside friction disc 15 transfer torques; pressing plate 18 holds out against by regulating bolt 10, regulates bolt 10 and end cap flange 07 by being connected and fixed by jam nut 11.
The gear ring 13 of this winch and reel 5 are connected by dowel fixes, HM Hydraulic Motor or motor 3 imput powers drive planetary reduction box 4 housings and rotate, planetary reduction box 4 housings are examined sheet 14,15 drive gear rings 13, reel 5 rotations by inside and outside rubbing, and reel 5 Wound steel ropes realize promoting operation to target; Moment limiting protector 6 inside and outside rub examine sheet 14,15 respectively with the housing of planetary reduction box 4, gear ring 13 with splined, clamping piston 16 relies on spring forces to compress inside and outside rubbing and examines sheet 14,15, makes it by the friction force transfer torque; Thereby the spinning in and out of regulating bolt 10 can change the size that the usable length of compression spring 17 changes spring force, thereby change the size of moment limiting protector 6 transfer torques.
