The invention relates to the technical field of transport vehicles, in particular to a double-cylinder composite lifting mechanism which comprises a concrete tank bottom beam, a crawler caisson beam and two lifting mechanisms. The crawler caisson beam is hinged to the concrete tank bottom beam. The two lifting mechanisms are arranged at the two ends of the crawler caisson beam respectively. Each lifting mechanism comprises a lifting oil cylinder, and the lifting oil cylinders are hinged to the concrete tank bottom beam and the crawler caisson beam respectively. According to the scheme, the included angle between the concrete tank bottom beam and the crawler caisson beam can be adjusted through the lifting mechanisms, the front end and the rear end of a concrete tank can be adjusted through the two lifting mechanisms, and the adjusting effect is better. The problems that a concrete tank truck slips, and concrete inclines and overflows during climbing can be prevented. The double-cylinder composite lifting mechanism has the advantages of being convenient to use, simple in structure and the like.

    本发明涉及运输车辆技术领域,具体涉及一种双缸复合举升机构,包括:混凝土罐底梁,履带车井字梁和两个举升机构;所述履带车井字梁与所述混凝土罐底梁铰接;两个所述举升机构分别设置于所述履带车井字梁的两端,所述举升机构包括举升油缸,所述举升油缸分别与所述混凝土罐底梁和所述履带车井字梁铰接。本方案中,通过举升机构能够调整混凝土罐底梁和所述履带车井字梁之间的夹角角度,设置两个举升机构,能够对混凝土罐的前端和后端均进行调节,使调节效果更好,能够防止爬坡时出现混凝土罐车打滑、溜车、混凝土倾斜溢出等问题,具有使用方便和结构简单等优点。
