The invention relates to the technical field of railway paving machines and discloses a grabbing mechanism of a crane for paving a railway. The grabbing mechanism comprises a housing. A driving shaftis movably connected in the top of the housing, a rotating rod is movably connected in the housing, and a connecting rod I is movably connected to the front surface of the rotating rod. According to the grabbing mechanism of the crane for paving the railway, the driving shaft is rotated, so that a left supporting rod and a right supporting rod move relatively and therefore, a left claw and a rightclaw are close to each other. As the left claw and the right claw are located in a same horizontal plane, the left claw and the right claw can grab a rail to achieve an effect of preventing the railfrom falling in a hoisting process. A rotating disc I and a rotating disc II are rotated, so that a telescopic rod I and a telescopic rod II are changed in length in the left supporting rod and the right supporting rod, so that the distances from the left claw to the left supporting rod and from the right claw to the right supporting rod are further changed, and therefore, an effect that equipmentwith different widths can be hoisted is achieved.

    本发明涉及铁道铺设机器技术领域,且公开了一种用于铁路铺设的吊车抓取机构,包括外壳,所述外壳顶部的内部活动连接有主动轴,所述外壳的内部活动连接有转动杆,所述转动杆的正面活动连接有连接杆一。该用于铁路铺设的吊车抓取机构,转动主动轴,使得左支撑杆和右支撑杆相对运动,进一步使得左爪与右爪相互靠近,因为左爪与右爪在同一水平面,所以此时左爪和右爪可以完成铁轨的抓取,从而达到了防止吊装过程中铁轨掉落的效果。转动转动盘一和转动盘二,可以使得伸缩杆一和伸缩杆二在左支撑杆和右支撑杆内部的长度发生改变,进一步改变了左爪到左支撑杆和右爪到右支撑杆的距离,从而达到了可以吊装不同宽度设备的效果。
