The invention discloses a secondary-beam-free engineering jacking device for an engineering dumper. The engineering jacking device comprises a frame assembly, a lifting system and a carriage, the frame assembly comprises a left longitudinal beam groove box and a right longitudinal beam groove box, the middles of the two longitudinal beam groove boxes are connected through a middle cross beam, an oil cylinder base of a hydraulic oil cylinder in the lifting system is arranged between the head and the middle cross beam and is close to the middle cross beam, and the power output end of the lifting system is arranged between the oil cylinder base of the hydraulic oil cylinder and the head. The power output end of the lifting system is hinged to the bottom of the carriage, and the bottom of one side of the carriage is hinged to the tail end of the frame assembly. According to the design, the compartment can be lifted through the lifting device of the horizontal top structure, the arrangement space of the hydraulic oil cylinder is large, the lifting height of the compartment is effectively increased, the strength of the frame assembly can be enhanced through the connecting plate, and the service life of the frame assembly is effectively prolonged.

    一种工程自卸车用无副梁工程顶装置,工程顶装置包括:车架总成、举升系统和车厢;车架总成包括左、右两根纵梁槽盒,两根纵梁槽盒的中部通过中部横梁相连接,举升系统中液压油缸的油缸座设置于车头与中部横梁之间,液压油缸的油缸座近中部横梁设置,举升系统的动力输出端设置于液压油缸的油缸座与车头之间,举升系统的动力输出端与车厢的底部铰接,车厢一侧的底部与车架总成的车尾端铰接。本设计不仅可以通过卧式顶结构的举升装置对车厢进行举升,液压油缸的布置空间较大,有效增加车厢举升高度,而且可以通过连接板增强车架总成强度,有效延长车架总成使用寿命。
