The utility model relates to an automatic-control friction clutching self-locking manual winch, which comprises a frame, a bottom support, a winding drum and a reduction transmission mechanism. The winding drum is driven by the reduction transmission mechanism to rotate. The automatic-control friction clutching self-locking manual winch is characterized in that a ratchet wheel mounted on the inner side of a transmission gear is arranged on a transmission spindle, a friction sheet is arranged on the inner side of the ratchet wheel, a shaft shoulder disk matched with the friction sheet on the lateral end surface of the ratchet wheel is arranged on the spindle, and the transmission gear on the spindle and the spindle are fittingly connected through threads to form a self-locking friction control mechanism. The winding drum can be controlled by a hand crank on the transmission spindle to realize traction, stopping, releasing and brake controlling without opening a converse pawl, and thereby the automatic-control friction clutching self-locking manual winch is convenient in operation, fine in using safety, high in operation efficiency and high in applicability.
Description
Technical field
The utility model relates to a kind of lifting, draw gear.
Background technology
In the prior art, especially for electric system electric pole is erect, the voltage transformer lifting, the lifting of using in the operations such as the wire erection of transmission line of electricity, traction strand mill apparatus is by support body, reel, the gear reduction transmission device, click is prevented reversing gearbox, band-type brake friction brake mechanism constitutes, this shaking lifting, the shortcoming deficiency of draw gear is, unclasp lifting at every turn, during drawing tension, all need to adopt earlier hand crank oppositely to control firmly the ratchet of the anti-reversing gearbox of manual unlocking click simultaneously, operate manual band-type brake friction brake mechanism controls unwrapping wire again, this device construction control operation is not only inconvenient, and danger is bigger, has carelessness to be easy to cause race line and hand crank counter-rotating to hurt sb.'s feelings slightly.
The utility model content
It is good that the purpose of this utility model provides a kind of performance, safe in utilization, and mill is manually twisted in easy to operate automatic control friction clutch self-locking
The utility model includes support body, underframe, reel, reduction gearing mechanism, reel drives by reduction gearing mechanism and rotates, it is characterized in that on transmission main shaft, being provided with self-locking friction control mechanism, by the transmission gear 51 that on transmission main shaft 5, is provided with, running-fit is equipped with ratchet 7 on transmission gear 51 inboard main shafts, on support body, be provided with the ratchet 70 that matches, have circular groove 71 at the ratchet inner side end, in this groove, be provided with friction lining 72, be provided with on the main shaft with the ratchet side end face on the shaft shoulder dish 52 of friction lining groove fit, transmission gear 51 on the main shaft is to be connected by screw thread fit with main shaft 5, is provided with positioning retainer ring 53 in transmission gear 51 outsides and forms.It is when by the hand crank rotating spindle, rotate with the transmission gear 51 relative main shafts 5 that spindle thread is connected, transmission gear 51 is produced to the inside move extruding ratchet 7 side end faces, friction lining 72 in the ratchet 7 is pressed with shaft shoulder dish 52 on the main shaft to be combined, main shaft 5, final gear 51 and ratchet 7 form fastening combination mutually, main shaft 5 drives reduction gearing mechanism by the transmission gear on it 51 and drives the reel rotation, under cooperating, the check of ratchet just changeing transmission work, and can not reverse, finish automatic one-way self-locking at work; When oppositely driving main shaft by hand crank, produce mobile laterally by screw thread fit bonded assembly transmission gear 51 with main shaft, transmission gear 51 reduces the squeese pressure with ratchet 7, friction force reduces, driving cog 51 is taken turns relative ratchet 7 and is produced slip, thereby make transmission gear 51 and reel realize backward rotation, loosen the reel traction; And cooperate with the extrusion friction of ratchet 7 by the forward and reverse drive main shaft of hand crank control transmission gear 51, reach friction clutch brake controllable function, so do not need at work to open under the situation of check ratchet, be that the may command reel is realized draw, stopping, loosening, brake and controlled every work by the hand crank on the main shaft.
The utility model is structural good, and volume is little, and is easy to operate, and safety in utilization is good, high efficiency, and applicability is strong.
