Abstract
The invention relates to a space controllable mechanism-type loader with a one-dimensional rotational moving arm and a three-dimensional rotational bucket, which comprises a loader body, the moving arm, the bucket, four drive bars, four connecting bars and four servo motors. The moving arm is capable of rotating one-dimensionally and independently, the bucket is capable of rotating three-dimensionally and independently, and the whole loader is capable of generating movement in space with four degrees of movement. The space controllable mechanism-type loader effectively overcomes the shortages that hydraulic elements of a hydraulic loader are high in processing precision requirement, high in maintenance cost, difficult in reliability guarantee, easy to leak oil and the like, and also solves the problems of insufficient movement flexibility, limited work space, low work efficiency and the like due to the fact that a plane loader only generates paths in a plane.
Description
Technical field
The present invention relates to the loader field, particularly a kind of one dimension rotates swing arm Three dimensional rotation scraper bowl space controllable mechanism formula loader.
Background technology
Loader is a kind of cubic metre of earth and stone construction machinery that is widely used in construction projects such as highway, railway, building, water power, harbour, mine; Be mainly used in bulk materials such as shovel dress soil, sandstone, lime, coal, also can dig operation the slight shovel of works such as ore, pan soil.Mostly traditional loader is hydraulic driven; Exist hydraulic system component process and assemble and require not length, leakage of oil, the long-term unsolved problem of maintaining cost higher engineering mechanical field of high, life-span; And mostly the loading executing agency of existing loader is plane mechanism; Driving through the swing arm hydraulic cylinder realizes the lifting and the decline of swing arm, and the driving of rocking arm hydraulic cylinder realizes the upset of scraper bowl.Because its structural limitations, the swing arm of this type hydraulic loader and scraper bowl all can only realize the motion output of single mobility in the plane, so also must cooperate running gear could accomplish loading tasks such as shovel dress, lifting, unloading.Also there is such problem in the controllable mechanism formula loader on plane.Problems such as output action underaction, working space are limited so construction site abominable at environment, that the space is narrow and small and the burst accident rescue site that needs shovel fortune fast, removes obstacles, traditional plane loader exist, inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of one dimension to rotate swing arm Three dimensional rotation scraper bowl space controllable mechanism formula loader; Drive by controllable motor; The connecting rod transmission; Each component process and assemble requires low; Shortcomings such as hydraulic loader Hydraulic Elements requirement on machining accuracy is high, the maintenance cost is high, reliability cannot say for sure to demonstrate,prove, easy leakage of oil can be effectively overcome, can also the track output in the plane, problems such as action underaction, the working space that causes is limited, inefficiency can only be realized by fine solution plane loader.
The present invention achieves the above object through following technical scheme:
One dimension rotates swing arm Three dimensional rotation scraper bowl space controllable mechanism formula loader; Comprise car body, swing arm, scraper bowl, first driving lever, second driving lever, the 3rd driving lever, the 4th driving lever, first connecting rod, second connecting rod, third connecting rod, the 4th connecting rod, first servomotor, second servomotor, the 3rd servomotor and the 4th servomotor, its structure and connected mode are:
Swing arm one end is connected with car body through first revolute pair; The swing arm other end is connected with scraper bowl through first spherical pair; First driving lever, one end is connected with first servomotor on being fixed in car body through second revolute pair; The first driving lever other end is connected with first connecting rod one end through the 3rd revolute pair, and the first connecting rod other end passes through the 4th revolute pair and is connected with swing arm, and second driving lever, one end is connected with second servomotor on being cemented in car body through the 5th revolute pair; The second driving lever other end is connected with second connecting rod one end through second spherical pair; The second connecting rod other end is connected with scraper bowl through the 3rd spherical pair, and the 3rd driving lever one end is connected with the 3rd servomotor on being cemented in car body through the 6th revolute pair, and the 3rd driving lever other end passes through the 4th spherical pair and is connected with third connecting rod one end; The third connecting rod other end is connected with scraper bowl through the 5th spherical pair; The 4th driving lever one end is connected with the 4th servomotor on being cemented in car body through the 7th revolute pair, and the 4th driving lever other end is connected with the 4th connecting rod one end through the 6th spherical pair, and the 4th connecting rod other end passes through the 7th spherical pair and is connected with scraper bowl.
Outstanding advantage of the present invention is:
1, drive by controllable motor, the connecting rod transmission, each component process and assemble requirement is low, can effectively overcome hydraulic loader Hydraulic Elements requirement on machining accuracy height, maintain shortcomings such as cost is high, reliability cannot say for sure card, easy leakage of oil.
2, swing arm can realize that independently one dimension rotates; Scraper bowl can be realized independently Three dimensional rotation; The motion of whole loading function implementation space four mobilities; Mechanism's output trajectory is flexible, working space is big, high efficiency, can be abominable at environment, construction site that the space is narrow and small and need load fast, remove obstacles, smooth burst accident rescue site can bring into play better acting on.
