Description
Technical field
The utility model relates to manual lifting gear field, but mainly is a kind of self-locking type crab winch.
Background technology
Common crab winch mainly is made up of handle, turning cylinder, coil of wire, extension spring and ratchet.Handle rotates, make turning cylinder and on turning cylinder fixing miniature gears rotate together, the big gear wheel engagement on miniature gears and the coil of wire drives coil of wire and rotates, thereby steel rope is wrapped on the reel of coil of wire, makes the weight lifting.When release handle, the gravity of weight just makes big gear wheel on the coil of wire as driving wheel, drives the counter-rotating of miniature gears and handle, freely falls until weight.Therebetween, though ratchet under the pulling force of extension spring, makes the velocity of rotation of gear slow down as far as possible, this safety hazard exists, and has hindered this low speed, the use of manual control device.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, but a kind of self-locking type crab winch is provided, and by the engagement action of ratchet and ratchet, realizes the self-locking of crab winch.
The utility model solves the technical scheme that its technical matters adopts: but this self-locking type crab winch, mainly comprise winch base assembly, center shaft, ratchet, ratchet, turning handle assembly, transmission gear and coil of wire assembly, the turning handle assembly is captiveed joint with center shaft, the coil of wire assembly is contained on the winch base assembly, the ratchet and first gear are installed on the described center shaft, wherein first gear is installed on the multiple-screw thread of center shaft, the profile of tooth of ratchet cooperates with the profile of tooth of ratchet, and torsion spring and ratchet are installed on the pawl installation axle in the winch base assembly; Be fixedly connected with second gear that is engagement fit with first gear on the coil of wire assembly.When crab winch promoted weight, clockwise direction promoted weight, and after unclamping turning handle, weight stops at by the locking phenomenon of the deadweight generation of object in the air.
Be fixedly connected with the gear protective cover by two second bolts, bullet pad, second nut and two the 3rd bolts, bullet pads on the described winch base assembly.
Described ratchet dust boot assembly is positioned on first hole of winch base assembly by ratchet dust boot hole, ratchet dust boot hole is positioned on second hole of winch base assembly, loads onto dust boot packing ring, third axle circlip, turning handle assembly, the 3rd plain cushion and the 3rd nut on the center shaft more successively.
The effect that the utility model is useful is: hoist, dropping process is steady, and is safe and reliable; The total compactness, from heavy and light, volume is little, and convenient disassembly can be vertical, laterally uses, and range of use is wide; The taper knob that is made by rubber makes total lighter and be convenient to install; Adopt built-inly, make crab winch can adapt to worse working environment from lock technology; Gear is through heat treatment process, longer service life; The gear protective cover makes gear and extraneous area of contact little, prevents steel rope and foreign object and gear generation interlock, influences the winch normal operation.Ratchet dust boot protection ratchet device contacts with extraneous, prevents that artificial maloperation from making failure mechanisms.

Principle of work:
Fig. 2-Fig. 4 is the structural representation of crab winch;
Fig. 5-Fig. 6 is the scheme drawing that turning handle assembly 28 rotates along clockwise direction, and when crab winch promoted weight, turning handle cover 29 moved turning handle assembly 28 in the direction of the clock.Transmission Handleset 28 drives center shaft 22 and rotates synchronously, first gear 17 moves along the multiple-screw thread 22-1 on the center shaft 22, and with first gear 17, thickening pad 18 and bakelite friction lining 19 all are pressed on the ratchet 20, friction force makes center shaft 22, first gear 17 and ratchet 20 firmly form the same direction of one and rotates synchronously, then first gear 17 on the center shaft 22 is as driving gear, and drive is the center anticlockwise motion with its ingear second gear 1-1 with drum shaft 1-3.Driving coil of wire assembly 1 simultaneously rotates, steel rope is wrapped on the rotating drum shaft 1-3, tractive force promotes weight, this moment, ratchet 20 rotated synchronously with center shaft 22, first gear, 17 clockwise directions, ratchet 20 is under the effect of external force, and the profile of tooth that contacts with ratchet 15 breaks away from ratchet 15, and ratchet 15 is under the torsion of torsion spring 14, though remaining the contact to ratchet 20 profiles of tooth, this moment, ratchet 15 did not play self-locking action;
Fig. 7 and Fig. 8 are the scheme drawings of crab winch self-locking, after unclamping turning handle assembly 28, coil of wire assembly 1 is subjected to the object deadweight and prolongs clockwise direction and rotate, this moment, the second gear 1-1 was as driving gear, drive with its ingear first gear 17 and rotate counterclockwise, first gear 17 moves along the multiple-screw thread 22-1 on the center shaft 22, and with first gear 17, thickening pad 18 and bakelite friction lining 19 all are pressed on the ratchet 20, friction force makes center shaft 22, first gear 17 and ratchet 20 firmly form the same direction of one and rotate synchronously, this moment, first gear 17 and ratchet 20 rotated counterclockwise synchronously, ratchet 15 is under the effect of torsion spring 14, the profile of tooth with ratchet 20 tightly is meshed, and self-locking takes place, and weight is parked in the air;
Fig. 9 and Figure 10 are the scheme drawings that turning handle assembly 28 rotates in the counterclockwise direction, when turning handle assembly 28 rotates in the counterclockwise direction, first gear 17 moves along the multiple-screw thread 22-1 on the center shaft 22 is reverse, the friction force of thickening this moment between pad 18, bakelite friction lining 19 and the ratchet 20 is eliminated, ratchet 20 is being not one with center shaft 22, ratchet 20 and ratchet 15 engagements, does not rotate the position.And first gear 17 is pieced together tightly on first plain cushion 5, make the center shaft 22 and first gear 17 and turning handle assembly 28 keep anticlockwise motion synchronously, first gear 17 and second gear 1-1 engagement, drive the second gear 1-1 and coil of wire assembly 1 and rotate, the weight pulsation-free is fallen along drum shaft 1-3 clockwise direction.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
