A bidirectional lifting mechanism of a large electric wheel dumper comprises a lifting mechanism body connected with a dumper hopper and a dumper frame, the lifting mechanism body comprises a first lifting cylinder, a second lifting cylinder, a third lifting cylinder and a fourth lifting cylinder, and the four lifting cylinders are evenly distributed at the four corners of the dumper hopper and the four corners of the dumper frame in a rectangular shape; each lifting cylinder is connected with the vehicle hopper and the vehicle frame through an upper pin shaft, an upper supporting seat, a lower pin shaft and a lower supporting seat, the vehicle frame and the vehicle hopper are connected through a hopper pin and a hopper supporting seat, and the number of the upper pin shafts, the number of the upper supporting seats, the number of the lower pin shafts, the number of the lower supporting seats, the number of the hopper pins and the number of the hopper supporting seats are in one-to-one correspondence with the number of the lifting cylinders; the lower supporting seat is fixed on the frame, the lower pin shaft simultaneously penetrates through the lower supporting seat to be connected with one end of the lifting cylinder, the upper supporting seat and the bucket support are fixed on the bucket, and the upper pin shaft simultaneously penetrates through the upper supporting seat to be connected with the other end of the lifting cylinder. By using the invention, the operation space of the dumper can be greatly reduced, and the dumper can meet the operation requirements of most of mine operation sites such as narrow and special operation sites.

    一种大型电动轮自卸车双向举升机构,包括与车斗和车架连接的举升机构,举升机构包括第一举升缸、第二举升缸、第三举升缸、第四举升缸,四个举升缸呈矩形均匀分布在车斗和车架的四个角落;各个举升缸与车斗和车架通过上销轴、上支承座、下销轴、下支承座进行连接,车架和车斗通过斗销、斗支座进行连接,上销轴、上支承座、下销轴、下支承座、斗销、斗支座的数量与举升缸的数量一一对应;下支承座固定在车架上,下销轴同时穿过下支承座和举升缸的一端实现连接,上支承座和斗支座固定在车斗上,上销轴同时穿过上支承座和举升缸的另一端实现连接。利用本发明,自卸车可大大缩小作业空间,可适应狭小特殊作业场地等绝大多数矿山作业场地的作业要求。
