Technical field
The utility model relates to a kind of ship loader luffing mechanism, particularly a kind of ship loader luffing mechanism that uses the planetary gear type reductor.
Background technology
The ship loader luffing mechanism is the important mechanism that ship loader is realized operation, and by the pitching transmission, ship loader can be realized the lifting and the decline of cantilever, slide tube are finished cabin and ship-loading operation.
Usually the ship loader luffing mechanism of each harbour use adopts " exposed gear transmission " mode, and the ship loader luffing mechanism of this type of drive has following defective:
1, technical elements: because the ship loader cantilevered weights is big, transmission speed is fast, so pitching transmission claimed accuracy is quite high.Common ship loader luffing mechanism adopts the exposed gear type of belt drive, i.e. drive pinion engagement cable drum bull gear.Utilize the engagement force of big or small exposed gear that power is passed on the reel, thereby realize luffing.Facts have proved: the accuracy of mesh of big or small exposed gear out of reach pitching far away transmission claimed accuracy, thus in the pitching process, produce violent vibration, As time goes on, vibration constantly exerts an influence to transmission accuracy, and causing at last can't normal operation.
2, cost aspect: because transmission accuracy causes long high vibration inadequately, the exposed gear transmission is very serious to the drive pinion wearing and tearing, and it is too high to change frequency; Vibration simultaneously also can cause the electric elements in machine room, the electric panel room to damage, and has so both increased the spare part cost, has increased maintenance cost again.
3, efficient aspect: the long high vibration that the exposed gear transmission produces is constantly aggravating the influence of transmission accuracy, in actual job, can only limit luffing speed like this, luffing speed is reduced in the vibration small range, have a strong impact on the normal operation of ship loader like this, greatly reduced ship-loading operation efficient.Both increase energy consumption, brought indirect economic loss again.
In sum, be necessary to design a kind of ship loader luffing mechanism in fact, to overcome the defective of prior art.
The utility model content
The purpose of this utility model is to improve transmission accuracy, avoids because the violent pitch vibration that causes inadequately of transmission accuracy, thereby improves the stability and the efficient of equipment, to overcome the defective that exists in the ship loader luffing mechanism in the past.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of ship loader luffing mechanism, the reel that comprises the cantilever that carries out pitching action, links to each other with described cantilever by steel rope, this ship loader luffing mechanism also comprises driving arm, the shock bracket that links to each other with this driving arm, be arranged on the main motor on the described driving arm, first drg that links to each other with described main motor by first elastomeric coupling, and the planet-gear speed reducer that links to each other with this first drg, the semiaxis of described planet-gear speed reducer and the semiaxis of reel interconnect.
As preferred implementation, described ship loader luffing mechanism also comprises a cover stand-by system, this stand-by system comprises the emergency decelerating machine that links to each other with described planet-gear speed reducer by manual plunging joint, second drg that links to each other with this emergency decelerating device, and pass through the emergent motor that second elastomeric coupling links to each other with described second drg.
As preferred implementation, the semiaxis of described planet-gear speed reducer and the semiaxis of reel interconnect by gear coupling.
As preferred implementation, the semiaxis of described planet-gear speed reducer and the semiaxis of reel interconnect by spline.
Ship loader luffing mechanism of the present utility model has fundamentally been avoided the low problem of transmission accuracy, and the vibration that has produced when having reduced transmission has guaranteed stability of transmission, has improved the reliability that equipment uses, and has also saved spare part and maintenance cost in addition.
