Abstract
The utility model relates to a spiral load disk brake traction device which belongs to a portable traction device for lifting. The utility model is principally characterized in that a friction wheel 9 is installed on a reversal back stop mechanism; trapezoidal threads are arranged between the friction wheel 9 and a shaft 11, and enable the reversal back stop mechanism to engage and disengage when the reversal back stop mechanism stresses; the reversal back stop mechanism is fixedly connected with a spool, and is driven by a gear. The utility model is braked by internal force generated in the mechanism by a heavy. When a rotary handle 1 rotates in the clockwise direction, the rotary handle 1 is engaged with a friction plate 6 by the spiral motion of the friction wheel 5 to generate large friction force; when the handle 1 does counterclockwise reversal, pressing force between the friction gear 5 and the friction plate 6, a ratchet wheel 7 and the friction plate 8 is reduced, and is balanced to the pressing force generated by the dead loads of the heavy to evenly loosen and move away. Thus, an automatic on-off reversal back stop mechanism is formed. The utility model has the advantages of handiness, labor saving, reliability, large traction force, smooth motion, convenient carrying and no electric power.
Description
The utility model belongs to portable lifting or draw gear.
Weight promotes or the present device that adopts of traction is comparatively heavy or need electric power.People are seeking always to be applicable to that field or family use portable weight to promote draw gear.
The purpose of this utility model be reliable design, dexterity, laborsaving, tractive force big, the use that is easy to carry, can be without the weight draw gear of electric power.
The technical solution of the utility model principal character is on the axle 11 of counter-rotating back-stop mechanism friction wheel 9 to be installed, can clutch when friction wheel 9 and axle have between 11 Acme thread to make the counter-rotating back-stop mechanism stressed, counter-rotating back-stop mechanism and spool fixed connection and by gear transmission.Also have such feature counter-rotating back-stop mechanism to constitute by the friction lining 4, ratchet 5, friction lining 6 and the ratchet 9 relative that are installed in successively on the axle 11 with ratchet 5 positions; The both sides symmetry of counter-rotating back-stop mechanism is installed friction wheel 4 and 9; By miniature gears 4 and big gear wheel 3 rolling touch formative gear transmissions; Between the big gear wheel 3 of screw motion on the axle 11, friction lining 4, ratchet 5, friction lining 6, friction wheel 4 and 9, connect with 0.0-0.2 millimeter free-running fit.
The utility model mainly is the interior dynamic braking that produces in mechanism by weight.When jiggle bar 1 right-hand revolution, miniature gears 4 rotations also drive big gear wheel 3 rotations, and big gear wheel 3 drives friction wheel 5 again and rotates; Friction wheel 5 meshes, compresses by screw motion and friction lining 6, produces powerful friction force, drives ratchet 7, and drives another friction wheels 9 and the rotation of steel rope (also can restrict with other) spool by another friction lining 8, thereby steadily promotes or hold up and draw weight.When handle 1 conter clockwise reverses, miniature gears 4 drives big gear wheel 3 counter-rotatings, the counter-rotating of friction wheel 5 spirals, thrust reduces between friction wheel 5 and friction lining 6, ratchet 7, the friction lining 8, and the thrust balance that produces with weight deadweight, evenly loosening leaving, make to produce between friction wheel 9, friction lining 8, the ratchet 7 and slide, thereby weight is steadily descended under the effect of gravity, when handle 1 stops operating, the interior compaction forces braking that the weight deadweight produces.
The utility model compact conformation, motion is steady, and machinery cooperates ingenious, has extensive use, contains commercial value.
Fig. 1 is a scheme drawing of the present utility model.
Embodiment:
Jiggle bar 1 is by imput shaft 2 and miniature gears 4 fixed connections; Miniature gears 4 rolls with axle 11 big gear wheels 3 and connects; Friction wheel 5 is installed from left to right successively again, friction lining 6, ratchet 7, friction lining 8, friction wheel 9 on the axle 11; Can clutch when friction wheel 9 and axle have between 11 Acme thread to make the counter-rotating back-stop mechanism stressed; Ratchet 5 is relative with ratchet 9 positions; Axle 11 and spool fixed connection, spool is provided with steel rope (also can restrict with other); The big gear wheel 3 of screw motion, friction lining 6 and 8, ratchet 5, friction wheel 4 and 9 connect with 0.1 millimeter free-running fit on axle 11; Axle 11 and the imput shaft 2 of doing gyroscopic movement connect the back by bracket supports with bearing fixing.
