Crane upper structure driving device

Abstract

The invention discloses a crane upper structure driving device. The crane upper structure driving device is provided with a main motor and a secondary motor. When the main motor is damaged, the secondary motor can supplement power in time. An arranged lifting driving device enables the main motor and the secondary motor to be separated rapidly and added to the crane upper structure driving device.Under the condition of insufficient power, the power of the crane upper structure driving device is improved by adding the secondary motor to the driving device. Through a second lifting cable roll driving device, a third lifting cable roll driving device and a first lifting cable roll driving device, independent forward and reverse rotation and stopping operations of three different lifting cable devices can be completed through one motor, no more motors need to be added, and energy consumption is greatly reduced. Meanwhile, the number of the motors is reduced, so that the production cost isgreatly lowered. The crane upper structure driving device has the beneficial effects that multiple lifting deices and one motor are arranged, the consumption is low, the power is high, and the secondary motor can be rapidly added into the driving device for power output when the main motor is damaged.

Description

technical field [0001] The invention belongs to the technical field of cranes; in particular, it relates to a driving device for the superstructure of a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range.

[0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The working characteristics of a crane are intermittent movements, that is, the corresponding mechanisms for retrieving, moving, and unloading in a working cycle are Alternately working, cranes are being developed and used more and more widely in the market, and as the core of the crane, the development of the crane superstructure driving device is becoming more and more important. The traditional crane superstructure driving device uses one motor corresponding to one crane. rope rollers, and thus make the existing multi-sling cranes more and more expensive to manufacture, and the volume is also increasing. The traditional multi-sling cranes have no backup motor or the backup motor is mostly separated from the main motor. When the main motor is damaged, Need to stop immediately, and then unwind the sling on the spare motor, which will cause the project to stop, which will greatly affect the progress of the project, thereby greatly increasing the project cost. At the same time, the traditional crane has no secondary load motor, so the lifting power cannot be changed. When lifting heavy objects that are heavier than the power of the motor, it cannot be lifted. Therefore, a crane superstructure with a single motor and multiple lifting devices, low consumption, high power, and damage to the main motor and auxiliary motors can be quickly incorporated into the drive device for power output. The imminent emergence of the driving device
