The invention discloses a grabbing and lifting mechanism for a railway cantilever mounting robot. The grabbing and lifting mechanism comprises a lifting arm base fixed on a rail travelling crane, a first arm rod with the rear end hinged with the top of the lifting arm base, a second arm rod with the rear end hinged with the front end of the first arm rod, a cantilever grabbing mechanism hinged with the front end of the second arm rod, a first lifting hydraulic cylinder with the end parts connected with the lifting arm bases and the first arm rod in a one-to-one correspondence mode and which drives the first arm rod to rotate with the hinged position of the first arm rod and the lifting arm bases as a fulcrum; and a second lifting hydraulic cylinder with the end parts connected with the first arm rod and the second arm rod in a one-to-one correspondence mode and which drives the second arm rod to rotate with the hinged position of the second arm rod and the first arm rod as the fulcrum.By means of the scheme of the grabbing and lifting mechanism for the railway cantilever mounting robot, the technical blank that no special railway cantilever mounting equipment exists in the prior art is filled up, and the grabbing and lifting mechanism has the advantages of being simple in structure, efficient and reliable in hoisting, high in mounting efficiency and the like and has high practical value and popularization value in the technical field of cantilever mounting.

    本发明公开了一种用于铁路腕臂安装机器人的抓举机构,包括固定在轨道行车上的升降臂底座,后端与升降臂底座的顶部铰接的第一臂杆,后端与第一臂杆的前端铰接的第二臂杆,与第二臂杆的前端铰接的腕臂抓取机构,端部一一对应与升降臂底座和第一臂杆连接、并驱动第一臂杆以与升降臂底座的铰接处为支点旋转的第一升降液压缸,以及端部一一对应与第一臂杆和第二臂杆连接、并驱动第二臂杆以与第一臂杆的铰接处为支点旋转的第二升降液压缸。通过上述方案,本发明填补了现有技术无专用铁路腕臂安装设备的技术空白,并且其具有结构简单、吊装高效可靠、安装效率高等等优点,在腕臂安装技术领域具有很高的实用价值和推广价值。
