Abstract

The invention relates to a single-engine power driving device and method and a crane. The single-engine power driving device comprises an lower crane engine, a speed changing box and a lower crane transfer case, and further comprises a central rotation transfer case, an upper crane transfer case and an upper crane hydraulic pump, the central rotation transfer case is connected with the lower crane engine or the speed changing box or the lower crane transfer case through a first transmission shaft, the central rotation transfer case is connected with the upper crane transfer case through a second transmission shaft, the power provided by the lower crane engine is changed in direction by the central rotation transfer case to penetrate through a vehicle rotation seat ring, and then is changed in direction again to be transmitted to the upper crane transfer case, and the upper crane transfer case is in driving connection with the upper crane hydraulic pump. According to the single-engine power driving device, the power transmission mode is a pure mechanical mode, the power is transmitted through the transmission shafts and the central rotation transfer case from a lower crane engine power system, working efficiency is high, energy losses are low, and the operation of upper crane hoisting in various working conditions can be ensured.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a single-engine power drive device, method and crane. Background technique [0002] Such as figure 1 As shown, in the field of construction machinery, a mobile crane is usually divided into a boarding part and a disembarking part through a vehicle frame 3, and the boarding part is connected to the disembarking part through a slewing bearing 6. The getting off part generally comprises getting off the cab 1, the getting off engine and accessories 2, the drive shaft 4, and the effect of the getting off part is to play the function of the load-carrying vehicle in the running process. The boarding part generally comprises the boarding operation room 5, the boarding engine and annex 7, and the effect of the boarding part is to implement lifting operations, and when the boarding part is working, it is necessary to perform a 360-degree turn on the getting off part. [0003] At pres...
