Description
Drive Apparatus for Crane and Crane
Cross-reference to Related Application
The present disclosure claims priority of Chinese Patent Application with the filing number 201810084128.9, filed on January 29, 2018 with the Chinese Patent Office and entitled "Drive Apparatus for Crane and Crane", the contents of which are incorporated herein by reference in their entirety.
Technical Field
The present disclosure relates to the technical field of mechanical transmission, in particular to a drive apparatus for crane and a crane.
Background Art
The mobile crane requires a drive apparatus in traveling and hoisting operations, the traveling drive portion is located in the carrier, and the hoisting operation drive portion is located in the superstructure. At present, drive apparatuses for mobile cranes can be divided into two categories:
1. twin-engine drive apparatus, which is currently mainly used for medium and large tonnage cranes, wherein the hoisting operation is driven by a superstructure engine device, by directly connecting the superstructure engine with a hydraulic oil pump, after the engine is started, the drive apparatus drives the hydraulic oil pump to operate in cooperation. With the twin-engine drive configuration, two independent sets of engine devices, such as radiator and muffler, are required, thus a large space is occupied, the arrangement is difficult, the weight is relatively large, and the cost is relatively high.
For the twin-engine drive apparatus, the superstructure engine usually is of a emission standard lower than that of the carrier engine, and for the crane, generally the superstructure engine runs for longer time, and is relatively more pollutant to the environment, moreover, after emission requirements of the superstructure engine are also stipulated in future emission regulations, it may be difficult to arrange a post-treatment device.
2. Single-engine-driven hydraulic transmission apparatus: the superstructure and the carrier share one drive apparatus, to perform traveling and hoisting operations; during travelling of the carrier, the carrier engine is connected with the clutch, and when the superstructure is running, a power takeoff of a carrier transfer gearbox is activated, the carrier engine is connected with a clutch, and torque is transmitted via a transmission mechanism. This drive apparatus can simplify the superstructure power system, optimizes space arrangement of the superstructure, and reduces the weight.
The single-engine drive apparatus mainly involves the following problems:
A hydraulic transmission mode determines that the carrier needs to be provided with a hydraulic oil tank and a main pump, and the arrangement space of the carrier needs to be compressed. As a swivel has a complex structure, in which a plurality of oil pipes are arranged, hydraulic failure easily occurs, which affects operation reliability. Meanwhile, the hydraulic oil reaches a superstructure execution unit via a relatively long pipe from the carrier hydraulic oil tank and then returns to a carrier hydraulic oil tank, or the hydraulic oil reaches the oil pump via a relatively long pipe from the superstructure hydraulic oil tank, then reaches a superstructure execution unit through a relatively long pipe and then returns to the superstructure hydraulic oil tank, which causes great loss of energy, and meanwhile affects the efficiency of crane operation.
Furthermore, as the superstructure and carrier share one engine, relatively high power and torque are demanded during traveling for the whole vehicle, thus engines with a relatively high-power output are usually selected, which has a power output much higher than the power required during the superstructure operation, then causing waste. Therefore, at present, large cranes usually adopt the twin-engine drive apparatus, including a large carrier engine and a small superstructure engine.
In crane designs, people are committed to optimizing weight distribution over years so as to improve the carrying capacity of the cranes. Therefore, how to cancel the superstructure engine and reduce the weight of the whole vehicle through innovation is always a topic studied by crane manufacturers.
To sum up, the energy consumption of the single-engine system of prior art cranes is relatively high.
