Track support for building machinery

Abstract

The invention provides a crawler frame, which is formed by a center frame and left and right track frames extending forward and backward on the left and right sides of the center frame, and is made of cast steel castings to connect the center frame part of the center frame and the track frame. Outriggers, the structure of the outriggers connecting the center frame of the track frame makes the soil rarely adhere to and accumulate, so it is easy to clean and simple to manufacture.

Description

technical field [0001] The present invention relates to a crawler frame of a construction machine, in particular to a crawler frame of a construction machine suitable for the lower cart part of a hydraulic excavator or the like. Background technique [0002] Conventionally, in rotary manipulators such as hydraulic excavators, crawler-type moving devices having endless track-type crawlers rotatably left and right are used. [0003] The crawler frame of this type of rotary manipulator generally has the following structure. It is provided with a rotary frame that can freely rotate and support an excavating device (excavator), an operating room, a motor, a machine cover, etc., and has a ring gear attached to the central part. The center frame of the rotary bearing, and a pair of left and right track frames connected to the left and right ends of the center frame and extending forward and backward. The front and rear ends of the track frame are respectively provided with idler wh...

AI Technical Summary

Problems solved by technology

[0014] These adhered and accumulated soil will soon invade the rotary bearing with the ring gear located in the upper center of the center frame, and cause damage to the rotary bearing

[0015] In addition, the mud attached and accumulated on the feet will move and accumulate on the upper surface of the track frame soon, and this accumulated mud will prevent the rotation of the upper runner or cause partial wear of the upper runner.

[0016] Although the accumulated soil can be removed by washing, a large amount of washing water and many cleaning man-hours are required to remove it, and the cleaning cost increases

[0017] In addition, people who rent out construction machines such as hydraulic excavators leave a large amount of soil at the cleaning place after cleaning the construction machines, and the disposal of such soil can also cause problems.
