The invention provides a pipe gallery lifting appliance and a hydraulic system. The pipe gallery lifting appliance comprises a main beam body, hydraulic oil cylinders and lifting rods, wherein one ends of the hydraulic oil cylinders are evenly arranged on the main beam body, the other ends of the hydraulic oil cylinders are connected with the lifting rods, the lifting rods are used for being connected with a pipe gallery body, the hydraulic oil cylinders are divided into at least three groups to be connected in parallel, the groups of hydraulic oil cylinders are connected in parallel, and the hydraulic oil cylinders in each group are adjacent to one another and are connected in series. According to the pipe gallery lifting appliance, the hydraulic oil cylinders are evenly arranged on the main beam body and are divided into at least three groups, the at least three groups of hydraulic oil cylinders can determine the levelness of the main beam body, and the hydraulic oil cylinders in each group are connected in series, so that the stresses of the hydraulic oil cylinders are the same, then the pipe gallery lifting appliance with a self-balancing function is realized, and damage to the pipe gallery during lifting can be reduced to the greatest extent in a balance state.

    本发明提供一种管廊吊具及液压系统,其中,管廊吊具包括:主梁体、液压油缸和吊杆,所述液压油缸的一端均匀设置在所述主梁体上,所述液压油缸的另一端与所述吊杆连接,所述吊杆用于连接管廊体,所述液压油缸分成至少三组进行并联,每组所述液压油缸并联,每组中的所述液压油缸彼此相邻且串联。本发明提供的管廊吊具,通过在主梁体上均匀的设置液压油缸,并且将液压油缸分成至少三组,至少三组的液压油缸可以确定主梁体的水平,每组内的液压油缸彼此串联,从而实现每个液压油缸的受力相同,进而实现具有自平衡功能的管廊吊具,平衡状态下可以最大化的降低管廊吊装时的损伤。
