Abstract
A nine-bar two-degree-of-freedom novel mechanism loading mechanism is composed of a frame, a movable-arm controlled branched chain and a bucket controlled branched chain. The movable-arm controlled branched chain is controlled through a first driving bar and performs movable-arm ascending and descending operations, the bucket controlled branched chain is controlled through a second driving bar to complete overturn of a bucket, and the movable-arm controlled branched chain and the bucket controlled branched chain cooperate with each other to complete loading and unloading operations of the mechanical loading mechanism. Member bars of the mechanical loading mechanism are all connected through revolute pairs, so that the shortcomings that a traditional full-hydraulic loading mechanism using sliding pairs is high in price, poor in reliability, high in maintenance cost and the like are overcome; compared to other mechanical-controllable loading mechanisms, the nine-bar two-degree-of-freedom mechanical loading mechanism which is compact in structure and high in rigidity is a brand new mechanism more superior in performance by adopting principles of kinematics and dynamics, and thereby being better in reliability and dynamic stability.
Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of nine bar two-freedom mechanical loader mechanisms.
Background technology
Loader is a kind of restoration in earth-rock construction machinery that is widely used in the construction projects such as road, harbour, mine, railway, and it is mainly used in the loose unpacked materials such as shovel dress soil, sandstone, also can dig operation to the slight shovel of the works such as ore, pan soil.Change that kind of different auxiliary working apparatus also can be bulldozed, the handling operation of lifting and unclassified stores.Loader is the engineering machinery being most widely used, and along with socioeconomic development, loader is more and more in the application of the occasions such as Municipal engineering, garbage-cleaning, construction work.Existing loader is mainly comprised of swing arm lifting mechanism and scraper bowl switching mechanism two parts, by boom cylinder and bucket cylinder, control the action that fulfils assignment respectively, although hydraulic system structure compactness, but hydraulic system is subject to oil overheating impact, mechanical efficiency is low, transmission stability is poor, and Hydraulic System Reliability is poor, maintenance, maintenance complexity and cost are higher.
Along with the development of theory of mechanisms and electromechanical integration, drive loader mechanism operation to become possibility with mechanical drive mode.Machinery driving efficiency is high, and existing electromechanical integration technology can overcome machine driving and easily transships the shortcomings such as destruction.But existing multiple degrees of freedom controllable type loader mechanism, mostly just existing hydraulic loader structure is carried out to simple modifications, utilize two linkages to replace the hydraulic system in hydraulic loader structure, the consideration of shortage to rod member transmission and hydraulic cylinder transmission dynamic property difference, causes mechanism's poor rigidity, and anti-overload ability is little, the shortcomings such as kinematics and dynamic performance are poor, be difficult to meet actual job needs, although solved the some shortcomings that hydraulic system exists, be difficult to be applicable to loader design and produce.
Summary of the invention
The problem that the object of the invention is to prior art existence provides a kind of nine bar two-freedom mechanical loader mechanisms, guaranteeing to meet under traditional loader job requirements and linkage prerequisite simple in structure, not only avoid existing fluid pressure type loader poor reliability, the shortcomings such as transmission efficiency is low, and guarantee that this mechanical type loader mechanism has kinematics, dynamic performance is good, the advantages such as the rigidity of structure is large, and anti-overload ability is strong.
The present invention achieves the above object by technical scheme once:
A kind of nine bar two-freedom mechanical loader mechanisms, are comprised of frame, swing arm control side chain, scraper bowl control side chain.
