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

Embodiment Construction
[0012] As shown in the figure, the specific implementation is as follows:
[0013] A crawler excavator includes an excavating device, an operating room 3, a crawler walking device 4, and a transmission system. The transmission system drives the excavator to work and the crawler walking device 4 to run. The excavating device includes one end installed in the operating room 3 One side of the cantilever 2 controlled by the hydraulic system and the bucket 1 installed on the other end of the cantilever 2, the crawler walking device 4 includes a tension buffer mechanism, a crawler 401, a crawler frame, a guide wheel 409, and a plurality of supporting weights The wheel 402 and the sprocket 403, the supporting wheel 402 is located between the guide wheel 409 and the sprocket 403. The supporting wheel 402, the guide wheel 409 and the sprocket 403 are all installed on the crawler frame. The crawler 401 surrounds the guide wheel 409 and the supporting weight The wheel 402 and the sprocket 4...

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 common construction machinery, which is widely used in various earthwork places. Hydraulic excavators are the main mechanical equipment for soil and rock development. They are widely used in industrial and civil construction. According to the technical status of domestic and foreign hydraulic excavators, and according to different walking devices, they are divided into crawler type, tire type and walking type. The excavator is walking It is easy to cause the crawler overhang amount to exceed the range of 10-20mm. When the overhang amount is too large, the track vibrates and aggravates the wear of the chain track section, the guide wheel, and the tooth surface of the sprocket, which may cause chain drop. The driving power will increase sharply, and because of the many obstacles on the underground road surface, it is easy for debris to ge...
