Abstract
The utility model discloses a light loader comprising a frame, a power transmission system and an operating device. Power of an engine (1) arranged at the rear portion of the frame is transmitted to a gearbox (14) under the frame through a torque converter (2), then is transmitted to a transmission bridge (10) by the gearbox through a front transmission shaft (13) and a rear transmission shaft (16) to drive wheels to rotate to form a power transmitting system; the operating device comprises a movable arm (6), a swing arm (7) a bucket (9), and a movable arm hydraulic cylinder (12). One end of the movable arm (6) is connected to the frame, and the other end of the movable arm (6) is provided with a bucket; one end of the swing arm (7) is connected to a swing arm hydraulic cylinder (5), and the other end of the swing arm (7) is connected to a link (8); the front end of the link (8) is provided with the bucket (9), and the movable arm hydraulic cylinder (12) drives the movable arm (6) to lift.
Description
Technical field
The utility model relates to the loader technical field.
Background technology
Low loader is mainly used to load and unload bulk cargo in heaps, also can carry out slight spading work.Be applicable to each department of the national economy such as building, railway, highway due to it, so its kind and output all developing comparatively fast, is a main machine in engineering machinery.
Loader is according to different instructions for uses, and development has formed different structure typess.Usually, by the difference of use occasion, be divided into outdoor with loader and down-hole loader; By running gear structure difference, be divided into wheel loader and crawler-type loader; Press the discharge way difference, be divided into front dump formula (front end type), rear-unloading type and slewing loader.
Summary of the invention
The wheel loader that provides a kind of open-air work to use is provided the purpose of this utility model.
The invention for achieving the above object, by the following technical solutions:
The low loader of the invention, comprise vehicle frame, the PWTN equipment of unifying; The power that is arranged on the motor at vehicle frame rear portion is passed to the gearbox of vehicle frame below through torque-converters, then by gearbox, power is passed to respectively to Transmission Bridge through front propeller shaft and inter-axle shaft, drives vehicle wheel rotation to form power drive system; Equipment is by the swing arm that an end is hinged on vehicle frame, the other end is installed scraper bowl, and an end and the rocking arm that the rocking arm hydraulic cylinder is connected, the other end is connected with connecting rod, be connected to the scraper bowl of connecting rod front end, the swing arm hydraulic cylinder composition of drive swing arm lifting.
Further, described vehicle frame is comprised of front and back two parts, and front and back two parts connect by hinge pin.
Further, described motor also drives to the hydraulic pump works of rocking arm hydraulic cylinder and swing arm hydraulic cylinder confession hydraulic oil.
Owing to having adopted technique scheme, the invention has following beneficial effect:
The rotation direction of rocking arm and scraper bowl direction of rotation, on linkage arrangement, form the reversion linkage; When the spading position, drive line angle is large, and the rocking arm hydraulic cylinder is again the effect of large chamber, therefore can produce larger spading power, and is easy to realize that scraper bowl sets level automatically, increases work efficiency.
The accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part.Schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.Give in accompanying drawing:
The front view that Fig. 1 is the invention preferred embodiment;
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
In conjunction with Fig. 1, the low loader of the present embodiment, comprise vehicle frame, the PWTN equipment of unifying; Wherein, vehicle frame 11 is comprised of front and back two parts, and front and back two parts connect by hinge pin 4, relies on hydraulic steering cylinder 15 can make front/rear frame relatively rotate around hinge pin, with realization, turns to.The power that is arranged on the motor 1 at vehicle frame rear portion is passed to the gearbox 14 of vehicle frame below through torque-converters 2, then by gearbox, power is passed to respectively to Transmission Bridge 10 through front propeller shaft 13 and inter-axle shaft 16, drives vehicle wheel rotation to form power drive system; Equipment, by the rocking arm 7 that swing arm 6, one ends are connected with rocking arm hydraulic cylinder 5, the other end is connected with connecting rod 8 that an end is hinged on vehicle frame, the other end is installed scraper bowl, is connected to the scraper bowl 9 of connecting rod 8 front ends, swing arm hydraulic cylinder 12 compositions of drive swing arm 6 liftings.Motor 1 also drives to rocking arm hydraulic cylinder 5 and swing arm hydraulic cylinder 12 and works for the hydraulic pump 3 of hydraulic oil.The upset of scraper bowl is driven and is realized by rocking arm and connecting rod by rocking arm hydraulic cylinder 5.
During work, swing arm is transferred to lower position, scraper bowl horizontal positioned ground, and the bucket point contacts to earth, start loader, scraper bowl inserts stockpile by tractive force, after the scraper bowl level is inserted the enough degree of depth of stockpile, and the loader stop motion, 12 actions of swing arm hydraulic cylinder promote swing arm 6, to fill material, complete the spading operating mode.Afterwards, rotate scraper bowl, shovel is got material, and bucket is received in 5 realizations of operation rocking arm hydraulic cylinder, then rocking arm hydraulic cylinder 5 lockings, and the lifting swing arm, lift the high suitable transporting position that arrives by scraper bowl, then drives loader, and emptying point is driven towards in load-carrying, completes the transportation operating mode.Keep rocking arm hydraulic cylinder 5 length constant, operation swing arm hydraulic cylinder 12, rise to upper limit position by swing arm, completes the extreme higher position operating mode.Operation rocking arm hydraulic cylinder 5 reversible buckets, to haulage vehicle or fixedly feed bin discharging, after discharging finishes, operation swing arm hydraulic cylinder 12 is transferred swing arm, realizes that scraper bowl sets level automatically, again enters shovel dress operating mode, carries out next working cycle process.
Should illustrate, those skilled in the art, on the basis of above preferred embodiment, within not breaking away from spirit of the present utility model and principle, any modification of doing, are equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
