The transmission system drives the work of the bulldozer and the operation of the crawler running device. The cantilever controlled by the hydraulic system and the bucket installed on the other end of the cantilever, the crawler belt traveling device is provided with a tension buffer mechanism. The present invention can realize the function of adjusting the tension by using very few components such as a slide plate, a positioning plate and an electric push rod, and the electric push rod can be operated by remote control, which is very convenient to operate. It can limit the free sliding of the skateboard, and at the same time, when the electric push rod is not working, it can double cooperate to prevent the sliding of the skateboard, so as to prevent the track from loosening.
Description
Technical field
The present invention relates to a kind of bulldozer, especially relate to a kind of crawler doer.
Background technology
Bulldozer is a kind of common construction machinery and equipment, is widely used in the place of various earthworks.Hydraulic bulldozer is native stone exploitation main mechanical, be widely used in industry and civil construction, according to the state of the art of domestic and international hydraulic bulldozer, according to the difference of running gear, be divided into crawler type, rubber-tyred and walking etc., bulldozer easily causes crawler belt overhang to exceed the scope of 10-20mm when walking, when overhang is excessive, crawler belt runout and aggravation chain rail joint and guide wheel, sprocket faces wearing and tearing, thereby easily fall chain phenomenon, when overhang is too small, walking driving power will sharply increase, and because down-hole road obstacle is many, be easy to occur that foreign material snap in the phenomenons such as crawler belt and occur.
Therefore regulate the tensioning degree of crawler doer very important, existing apparatus setting have loosening device or a tightening device, all more complicated troublesome poerations, cost is also higher.
Summary of the invention
The object of the invention is to bulldoze into track takeup complex structure for existing, the problem of inconvenient operation, a kind of crawler doer is provided, the present invention is by adopting few parts such as slide plate, locating plate and electric pushrod just can realize the function that regulates tensioning, and electric pushrod can be by remote manipulation, easy to operate, be provided with dowel bolt simultaneously and can limit being free to slide of slide plate by being fixed on locating plate, simultaneously in the time that electric pushrod is not worked, can dual cooperation prevent slide plate slides, thereby play the object that prevents that crawler belt is loosening.
The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of crawler doer, comprises bulldozing device, operator's compartment, track unit and driving system, described transmission system drives bulldozer work and the operation of track unit, bulldozing device comprises that an one end is arranged on the cantilever by HYDRAULIC CONTROL SYSTEM of operator's compartment one side and is arranged on the scraper bowl on the cantilever other end, and described track unit comprises tensioning buffer gear, crawler belt, track frame, guide wheel, a plurality of caterpillar wheels and sprocket wheel, caterpillar wheel between guide wheel and sprocket wheel, caterpillar wheel, guide wheel and sprocket wheel are installed on track frame, and crawler belt is around guide wheel, caterpillar wheel and sprocket wheel setting, and guide wheel, caterpillar wheel and sprocket wheel form wheeled mechanism, and tensioning buffer gear comprises slide plate, locating plate, dowel bolt and electric pushrod, locating plate and electric pushrod are all fixed on track frame, the external part of electric pushrod drives guide wheel horizontal slip together by promoting slide plate, reach the object of tensioned tracks by guide wheel horizontal slip, dowel bolt is fixed on being free to slide with restriction slide plate in the positioning groove on locating plate through slide plate by slide plate.
Described sprocket wheel is connected with the dynamical axis of driving system.
The invention has the beneficial effects as follows: the present invention is by adopting few parts such as slide plate, locating plate and electric pushrod just can realize the function that regulates tensioning, and electric pushrod can be by remote manipulation, easy to operate, be provided with dowel bolt simultaneously and can limit being free to slide of slide plate by being fixed on locating plate, simultaneously in the time that electric pushrod is not worked, can dual cooperation prevent slide plate slides, thereby play the object that prevents that crawler belt is loosening.
