The invention discloses a lifting device for expressway indicating road sign mounting. The lifting device comprises two supporting seats. Universal wheels are mounted at both ends of the front ends ofthe bottom surfaces of the two supporting seats. The supporting seats are internally hollow. The supporting seats are internally provided with first hydraulic cylinders. The opposite sides of the twosupporting seats are slidably connected with clamping rods. The clamping rods and the output ends of the first hydraulic cylinders are connected by bolts. A connecting rod is arranged between the topends of the two supporting seats. The lifting device solves problems caused by the common method that lifting by working personnel is adopted and labor-consuming, so that the expressway indicating road sign mounting efficiency is too low. By means of improving and optimizing the structure of the lifting device, an indicating road sign and a transverse rod can be conveniently lifted by the liftingdevice, are decoupled from the ground and are matched with a vertical rod, so that the indicating road sign and the transverse rod are conveniently connected, and connection of the transverse rod andthe vertical rod is facilitated as well.

    本发明公开了一种高速公路指示路牌安装用起吊装置,包括支撑座,所述支撑座设有两个,两个所述支撑座底面前端两端均安装有万向轮,所述支撑座内部中空,且支撑座内部设有第一液压缸,两个所述支撑座相对的一面滑动连接有卡杆,所述卡杆和第一液压缸的输出端通过螺栓连接,两个所述支撑座顶端之间设有连接杆,本发明解决常用的方法是由工作人员抬起,这种方法过于耗费人力,从而导致高速公路指示牌安装效率太低的问题,通过对起吊装置的结构进行改良和优化,使得起吊装置方便对指示路牌和横杆进行吊起,使得指示路牌和横杆离开地面并和立杆配合,从而方便指示路牌和横杆连接在一起,同时也便于横杆和立杆连接。
