The utility model relates to a rear axle housing trailer structure for a mining dump truck, which includes a trailer hanger fixed on the rear axle housing of a dump truck. The trailer hanger ear consists of the main ear and a number of hoist reinforcement, the main crane is standing on the rear axle housing, the hanger reinforcement is distributed on both sides of the main hanger, the hanger is connected with the main ear and the other end is connected to the main ear, and the other end is connected to the main ear. The other end is connected to the other end. The arc transition plate is arranged at both ends of the main lifting lug, and the arc transition plate adopts a large circular arc to realize the smooth transition of the height of the axle housing after the main lifting lug is protruding. The utility model adds Trailer lifting lugs on the rear axle housing of the tail part of the mining dump truck to realize dragging and fixing points for the accident vehicle. The structure of large circular arc transition and rear axle housing is adopted to avoid the damage to the rear axle housing when the trailer is trailer, which reduces the accident caused by the drag and drop accident car in the mining dump truck and ensures the service life of the whole vehicle.
【技术实现步骤摘要】
一种矿用自卸车后桥壳拖车结构
本专利技术涉及一种拖车结构,尤其涉及一种矿用自卸车后桥壳拖车结构。
技术介绍
矿用卡车是露天矿山开采和大规模土方建设中的关键设备,是用于矿石或土方运输的专业设备,具有载重大、工作效率高等特点,所处的工作环境恶劣,工况复杂。目前矿用卡车有朝超大型化、巨型化方向发展的趋势,当矿用卡车出现故障时,将矿用自卸车拖到安全位置成为一个问题。大型矿用自卸车自重大,一般设备很难将其拖动。矿区一般采用相同型号的矿用自卸车将出现故障的矿用自卸车拖走。但是由于矿用自卸车尾部没有设计有拖车机构,无法固定拖车绳。加之矿用自卸车需要的拖车力较大,易造成对拖车的损坏。
技术实现思路
本技术为了解决自卸车拖车时,拖动力大,易造成前车后壳损坏的问题,提供了一种新型的矿用自卸车后桥壳拖车结构。为了解决上述问题,本专利技术所采取的技术方案为:一种矿用自卸车后桥壳拖车结构,包括固定在自卸车后桥壳上的拖车吊耳,所述拖车吊耳包括主吊耳和若干吊耳加强筋,所述主吊耳立于所述后桥壳上,所述吊耳加强筋分布在主吊耳两侧,所述吊耳加强筋一端连接主吊耳,另一端逐渐过渡至后桥壳面;所述主吊耳两端设有弧形过渡板,所述弧形过渡板采用大圆弧实现主吊耳凸出后桥壳高度的平稳过渡。进一步的,所述主吊耳和所述弧形过渡板处于同一平面上,所述吊耳加强筋与所述主吊耳形成“艹”形结构。进一步的,所述吊耳加强筋对称分布在主吊耳上下两侧。进一步的,所述吊耳加强筋连接主吊耳一端凸出后桥壳的高度与主吊耳耳孔与后桥壳的相对距离相同。进一步的,所述弧形过渡板厚度小于所述主吊耳的厚度。进一步的,所述弧形过渡板的切线与连接处后桥壳 ...
