Abstract
The invention relates to a space controllable mechanism type loader with a movable arm capable of two-dimensionally rotating and a bucket capable of one-dimensionally rotating. The space controllable mechanism type loader comprises a loader body, the movable arm, the bucket, three driving rods, three connecting rods and three servo motors, the movable arm can two-dimensionally rotate independently, the bucket can one-dimensionally rotate independently, and the total loader can realize spatial movable output with three degrees of movement. The space controllable mechanism type loader can effectively overcome shortcomings that requirements on processing precision of hydraulic elements of a hydraulic loader are high, repair and maintenance costs are high, reliability is difficult to be guaranteed, oil leaks easily and the like. In addition, the space controllable mechanism type loader can resolve problems that a planar loader only can realize output along a trace in a plane, actions are not flexible, a working space is limited, work efficiency is low, and the like.
Description
Technical field
The present invention relates to the loader field, particularly a kind of two dimension is rotated the swing arm one dimension and is rotated 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 two dimension to rotate the swing arm one dimension and rotate 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:
A kind of two dimension is rotated the swing arm one dimension and is rotated scraper bowl space controllable mechanism formula loader; Comprise swing arm, scraper bowl, first driving lever, second driving lever, the 3rd driving lever, first connecting rod, second connecting rod, third connecting rod, first servomotor, second servomotor, the 3rd servomotor and car body, its structure and connected mode are:
Swing arm one end is connected with car body through first Hooke hinge; The swing arm other end is connected with scraper bowl through first revolute pair; First driving lever, one end is connected with first servomotor on being cemented in car body through second revolute pair, and the other end is connected with first connecting rod one end through second Hooke hinge, and the first connecting rod other end passes through first spherical pair and is connected with swing arm; Second driving lever, one end is connected with second servomotor on being cemented in car body through the 3rd revolute pair; The other end is connected with second connecting rod one end through the 3rd Hooke hinge, and the second connecting rod other end passes through second spherical pair and is connected with swing arm, and the 3rd driving lever one end is connected with the 3rd servomotor on being cemented in car body through the 4th revolute pair; The other end is connected with third connecting rod one end through four-stringed bowed instrument gram hinge, and the third connecting rod other end is connected with scraper bowl through the 3rd spherical pair.
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 two dimension is rotated; Scraper bowl can realize that independently one dimension rotates; The motion of whole loading function implementation space three 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.
