Problems solved by technology

The above-mentioned traditional feeding cranes have a common feature, that is, the two sets of lifting driving mechanisms of the feeding crane are not connected with each other. Once one of the driving mechanisms or its electric control system breaks down, the operation can only be stopped and waited for repair; both Affect the completion of the production plan, and cause huge economic losses to the production unit

Abstract

The invention belongs to the hoisting mechanism used for a charging crane and an operation method thereof, particularly relating to a planetary transmission hoisting mechanism used for the charging crane and an operation method thereof. The method is characterized in that a planetary reduction gear contained a 2K-H-shaped planetary gearing of NGW is adopted, the combination of a motor, a brake and a winding drum group is connected on the planetary reduction gear to form the planetary transmission hoisting mechanism, wherein the planetary reduction gear consists of a case body, a Z16 gear, a first output shaft, a Z15 gear, a Z14 gear, a first input shaft, a Z13 gear, a Z11 gear, a Z12 gear, a second input shaft, a Z21 gear, a Z22 gear, a planetary gearing, a random shaft, a Z32 gear, a Z31 gear, a Z23 gear, a Z24 gear, a Z25 gear, a second output shaft and a Z26 gear. The mechanism has scientific design and compact structure, thus not only being applicable to different working conditions and operated flexibly, but also being capable of finishing the charging work under fault condition so as to guarantee that the production plan is finished; in addition, the mechanism has the advantages of safe and reliable operation, energy-saving, convenient usage and the like.

Description

technical field [0001] The invention belongs to the hoisting mechanism of a crane for feeding in material handling lifting equipment, in particular, it relates to a set of driving mechanisms in the hoisting mechanism of a feeding crane or its electric control system. When a failure occurs, the remaining set of driving mechanisms A planetary transmission hoisting mechanism for a charging crane still capable of working normally and an operation method thereof. Background technique [0002] At present, in the case of bulk material handling, the crane for feeding is the main special handling equipment, such as the crane for feeding in steelmaking and iron making in steel mills. According to the requirements of feeding, its lifting mechanism must have two sets of lifting and driving mechanisms. , and each set of driving mechanisms lifts a set of spreaders separately; these two sets of spreaders jointly lift a trough or tank; these two sets of lifting drive mechanisms can drive th...
