Problems solved by technology
[0004] The purpose of the present invention is to provide a crawler excavator for the problems of complex structure and inconvenient operation of the existing digging crawler tensioning device. The present invention can 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 excavator which comprises an excavating device, an operating room, a crawler walking device and a transmission system. The transmission system drives the excavator to work and drives the crawler walking device to operate. The excavating 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 excavator, 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 an excavator, in particular to a crawler excavator. Background technique [0002] Excavator is a kind of common construction machinery, which is widely used in various earthwork operations. Hydraulic excavator is the main mechanical equipment for soil and rock development, widely used in industrial and civil buildings, according to the technical status of hydraulic excavators at home and abroad, according to the different walking devices, it is divided into crawler type, tire type and walking type, etc. The excavator is walking 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 walking The driving power will increase sharply, and because there are many obstacles on the underground road surface, it is easy for sundries to get stuck in the track and so on. [0003]...
