The invention relates to the technical field of engineering machinery, and discloses a rubber crawler chassis for engineering machinery. The rubber crawler chassis comprises an output roller, a crawleris movably connected to the outer side of the output roller, a connecting frame is movably connected to the inner side of the crawler and close to the back surface of the output roller, and a connecting roller is movably connected to the front surface of the connecting frame. The inner wall of the connecting roller is movably connected with a judging mechanism, the front face of the connecting frame is movably connected with a roller shaft, and the back face of the output roller is movably connected with a driving shaft. In the working process of the rubber crawler chassis for the engineering machinery, through the arranged connecting mechanism and the arranged judging mechanism in a matched mode, the judging mechanism responds to crawler breakage in the using process, the connecting mechanism is changed, and the output roller is separated from the driving shaft, so that the driving shaft is prevented from driving the rubber crawler to continuously rotate while the rubber crawler is broken, expansion of breakage of the rubber crawler is prevented, scrapping of the rubber crawler is avoided, economic losses are reduced, and the service life of the rubber crawler chassis is prolonged.

    本发明涉及工程机械技术领域,且公开了—种工程机械用橡胶履带底盘,包括输出辊,所述输出辊的外侧活动连接有履带,所述履带的内侧且靠近所述输出辊的背面活动连接有连接架,所述连接架的正面活动连接有连接辊,所述连接辊的内壁活动连接有判断机构,所述连接架的正面活动连接有辊轴,所述输出辊的背面活动连接有驱动轴。该工程机械用橡胶履带底盘在工作中,通过设置的连接机构,以及配合设置判断机构,使用时判断机构对履带断裂做出反应,使得连接机构发生变化,使得输出辊与驱动轴分离,实现了避免橡胶履带断裂的同时驱动轴会带动橡胶履带继续转动,防止橡胶履带断裂扩大,避免橡胶履带的报废,降低了经济损失,提高了橡胶履带底盘的使用寿命。
