Mechanical and hydraulic composite recovery and regeneration integrated winch driving system

Abstract

The invention discloses a mechanical and hydraulic composite recovery and regeneration integrated winch driving system which comprises a winch driving system, an energy recovery system, a rotary hydraulic system, a power transmission control system and the like. According to the winch rotation system, the winch driving system and the rotation hydraulic system both adopt closed loops, switching consumption of energy on a multi-way valve and loss of energy on a balance valve are reduced, the energy-saving and environment-friendly requirements are met, meanwhile, the characteristic of repeatability of the winch rotation working condition is integrated, the hydraulic energy accumulator and the pump motor are adopted to achieve the integrated energy recovery mode of the winch system and the rotation system, the transmission characteristic of the transfer case is fully utilized, one set of energy system acts on operation under different working conditions, the load rate of an engine is reduced, the output power of the engine is reduced, and the space utilization rate of whole machine installation is greatly improved, and the whole machine cost is reduced.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a winch drive system integrated with mechanical and hydraulic composite recovery and regeneration. Background technique [0002] In the 21st century when resources are scarce, energy conservation and emission reduction has become an important goal in the field of construction machinery at home and abroad. Among them, the hoisting system and the slewing system have important applications in major construction machinery such as cranes and rotary drilling rigs. The hoisting system can realize vertical lifting, horizontal or oblique pulling of heavy objects, and will continue to reciprocate in actual work. And lowering, the slewing system can make the mechanical slewing part realize slewing motion around its center line, so reducing the energy consumption of the hoisting system and slewing system is of great significance to the energy saving of the whole machine. ...

AI Technical Summary

Problems solved by technology

[0003]At present, in construction machinery, especially in cranes, rotary drilling rigs and other models, whether it is in the process of hoisting and lowering, or in the rotation brake There is a lot of energy loss in the process, but in actual operation, the machine needs to be able to realize repeated lifting and turning operations. It is not a single repetitive lifting operation or a single repetitive rotation operation, and the existing energy-saving modes focus more on where a single case is analyzed

Considering the reasonable installation space of the model, when the hoisting system and the slewing system adopt different energy recovery methods and require different hydraulic accumulators, it will cause difficulties in installation and lead to redundancy of the entire system
