Problems solved by technology
[0004] The purpose of the present invention is to provide a crawler bulldozer for the problems of complex structure and inconvenient operation of the existing bulldozing crawler tensioning device. Realize the function of adjusting the tension, and the electric push rod can be operated by remote control, which is very convenient to operate. At the same time, there are positioning bolts fixed on the positioning plate to limit the free sliding of the slide plate. At the same time, when the electric push rod is not working, it can be double-coordinated. Prevent the sliding of the skateboard, so as to prevent the track from loosening

The invention discloses a crawler dozer which comprises a dozing device, an operating room, a crawler walking device and a transmission system. The transmission system drives the dozer to work and drives the crawler walking device to operate. The dozing device comprises a cantilever and a bucket, wherein the cantilever is controlled by a hydraulic system, one end of the cantilever is installed on one side of the operating room, and the bucket is installed at the other end of the cantilever. A tensioning buffering mechanism is arranged in the crawler walking device. According to the crawler dozer, few parts such as a sliding plate, a positioning plate and an electric drive pusher can be used for achieving the function of adjusting and tensioning. In addition, the electric drive pusher can be operated through a remote control, and operation is quite convenient. Meanwhile, a positioning bolt can be arranged to limit free sliding of the sliding plate by being fixed to the positioning plate, when the electric drive pusher does not work, dual matching can be achieved to prevent the sliding plate from sliding, and therefore the purpose of preventing a crawler from loosening is achieved.
Description
technical field [0001] The invention relates to a bulldozer, in particular to a crawler bulldozer. Background technique [0002] Bulldozer is a kind of common engineering machinery, which is widely used in various earthwork operations. Hydraulic bulldozers are the main mechanical equipment for earth and rock development, widely used in industrial and civil buildings. According to the technical status of hydraulic bulldozers at home and abroad, according to the different walking devices, they are divided into crawler type, tire type and walking type, etc. Bulldozers are easy to cause damage when walking. The overhang of the track exceeds the range of 10-20mm. When the overhang is too large, the track will vibrate and aggravate the wear of the chain rail joints, guide wheels, and sprocket tooth surfaces, which will easily cause chain drop. If the overhang is too small, the driving power will decrease. It increases sharply, and because there are many obstacles on the undergrou...
