Described front gear 11 equates with backgear 19 rotational angular.
The principle of work of friction-type jack up unit of the present utility model is:
Electrical control cubicles 5 is used to provide power supply and carries out electrical control, the Poewr transmission mechanism that motor 1, drg 2, retarder 3 are formed, after the rotating shaft of motor 1 is rotated, slow down through retarder 3, link to each other by the gear wheel shaft of coupler 4 with backgear 19, driving gear 20 and backgear 19 coaxial rotation, driving driven gear 8 and intermediate gear 9 are done and are relatively rotated, because backgear 19, intermediate gear 9, front gear 11 mesh successively, intermediate gear 9 drives front gear 11 and rotates, and direction is identical with backgear 19 with driving gear 20.Forerunner's rope sheave 12 and rear-guard rope sheave 11 are driven to do in the same way by gear wheel shaft and rotate simultaneously.Owing to pass in the hollow shaft 21 of center shaft 22 by driven gear 8, forerunner's rope sheave 12 and rear-guard rope sheave 17 all are close to center shaft 22, so under the effect of the friction force that the forerunner's rope sheave 12 that rotates in the same way and rear-guard rope sheave 17 provide, center shaft 22 takes place to rotate in the same way, drives storage rope reel 13 and rotates.Be wrapped in the steel rope 16 on forerunner's rope sheave 12 and the rear-guard rope sheave 17, by being wrapped in behind the fixed pulley 18 on the storage rope reel 13, when steel rope leads into or promote, the rope speed that can guarantee storage rope ground floor with drive the consistent of rope, increase along with the storage rope number of plies in the storage rope reel 13, rope speed is more and more faster, can adjust by wet friction clutch 14 consistent with the linear speed that drives rope, fast can skidding; When steel rope when involving or descend, along with the minimizing of the storage rope number of plies in the storage rope reel 13, rope speed can be more and more slower, drags storage rope reel 13 by steel rope 16 and rotate, and adjusts to reach consistent with the speed of driving rope by wet friction clutch 14.The moving into of 15 pairs of ropes of mono-directional overrun clutch lays out or alternating action is played in lifting, through driving the rope frictional transmission, the storage rope tension is very little, and default normal pressure thrust guarantees that the pulling force of steel rope 16 can turn round winch safely and reliably in the rated load scope on wet friction clutch 14.In case overloaded, steel rope 16 pulling force are greater than setting pulling force, and wet friction clutch 14 can skid, thereby has played the safety guard-safeguard effect.
Two groups of mono-directional overrun clutchs 6 and 15 are used for unidirectional delivery motion or moment of torsion.
Front gear 11 equates with backgear 19 rotational angular, thereby has guaranteed that forerunner's rope sheave 12 is identical with the rotating speed of rear-guard rope sheave 17, slow-roll stabilization.
