The invention discloses a composite floor assembling type lifting tool. The composite floor assembling type lifting tool comprises a bottom plate and a hook, wherein the hook is fixedly connected to the top of the bottom plate, a hydraulic cylinder is fixedly connected to the lower part of the interior of a shell, the output end of the hydraulic cylinder is fixedly connected with a long rod, the outer wall of the long rod is rotationally connected with two first connecting rods through pin shafts, one of the ends of the two first connecting rods is rotationally connected with a second connecting rod through a pin shaft, and one of the ends of the two second connecting rods is rotationally connected with a sector gear through a pin shaft. According to the composite floor assembling type lifting tool, through the cooperation of the shell, the hydraulic cylinder, the long rod, the first connecting rods, the second connecting rods, the sector gears, rack clamping blocks, a screw rod, a nut and a handle, the long rod enables the second connecting rods to rotate through the first connecting rods, the second connecting rods drive the sector gears to rotate, the sector gears enable the two rack clamping blocks to move towards the middle, so that the vertical direction is fixed, and the problem that the fixing of the composite floor assembling type lifting tool on a floor is relatively loose is solved.

    本发明公开了一种叠合楼板组拼式起吊工具,包括底板和挂钩,所述底板的顶部固接有挂钩,所述外壳的内部下方固接有液压缸,所述液压缸的输出端与长杆相固接,所述长杆的外壁通过销轴转动连接有两个第一连杆,两个所述第一连杆的一端通过销轴均与第二连杆转动连接,两个所述第二连杆的一端通过销轴均转动连接有扇形齿轮。该叠合楼板组拼式起吊工具,通过外壳、液压缸、长杆、第一连杆、第二连杆、扇形齿轮、齿条夹块、螺杆、螺母和把手之间的配合,长杆通过第一连杆使第二连杆转动,第二连杆带动扇形齿轮转动,扇形齿轮使两个齿条夹块向中间移动,使得上下的方向得到固定,解决了叠合楼板组拼式起吊工具对楼板的固定比较松懈的问题。
