Problems solved by technology

[0003] Due to the limitations of the structure and control principle of the existing large-scale mining excavator tension wheel and crawler device, the copper sleeve wears faster and the service life is relatively short; the wear standard of the copper sleeve is not clear, so the replacement cycle cannot be controlled, and further possible The tension shaft and the tension wheel are directly contacted and worn, resulting in the wear and tear of the tension shaft and the scrapping of the tension shaft; when replacing the copper sleeve and the tension wheel device in the prior art, the replacement is more complicated and the cycle is longer, resulting in high maintenance costs

Abstract

The invention relates to the technical field of tracks, in particular to a track device and a tension wheel device. The tension wheel device is mounted on a track frame with a first extension portion and a second extension portion, and the first extension portion and the second extension portion are provided with tension shaft seats respectively. The tension wheel device comprises a tension wheel, a tension shaft and two bushings, wherein the tension wheel is arranged between the first extension portion and the second extension portion; the tension shaft and the tension wheel are fixed coaxially, and two sides of the tension shaft are rotationally fixed to the first extension portion and the second extension portion; the two bushings sleeve two sides of the tension shaft and are positioned between the tension shaft and the corresponding tension shaft seats and fixedly connected with the tension shaft seats. The track device and the tension wheel device have advantages that the service life of the device is prolonged, and a replacement period is shortened.

Description

technical field [0001] The present disclosure relates to the technical field of crawler belts, and in particular, to a tension wheel device of a mining machine and a crawler track device including the tension wheel device. Background technique [0002] The crawler device is an important part of the large mining excavator. The life and replacement cycle and time of the tension wheel in the crawler device directly affect the reliability and production efficiency of the equipment. [0003] Due to the limitation of the structure and the control principle of the large-scale mining excavator tension wheel and crawler track device in the prior art, the copper sleeve wears quickly and the service cycle is relatively short; the wear standard of the copper sleeve is not clear, so the replacement cycle cannot be controlled, and further possible This leads to direct contact and wear between the tensioning shaft and the tensioning wheel, resulting in wear and scrapping of the tensioning ...
