Abstract

The invention relates to a large-diameter cylinder body outer wall climbing device, in particular to a lifting device. The device solves the problems of the existing large-diameter cylinder body outer wall climbing device using a steel wire rope reel mechanism: a steel wire rope is easily polluted, a cylinder body is damaged, the steel wire rope is hard to fix, and a platform is unstable when being lifted. The device comprises a motor installed on the platform, a speed reducer and roller wheels installed on the platform closely to the outer wall of the cylinder body, wherein the two roller wheels are symmetrically arranged on the platform by movable brackets; a support oil cylinder is installed between the two movable brackets; the motor drives the speed reducer to lead the roller wheels to roll up and down along the cylinder wall by chains; a brake skid shoe is arranged under the platform by a skid shoe bracket, and a brake oil cylinder is positioned between the skid shoe bracket and the platform; and the platform is also provided with a hydraulic station, an electrical system, an electrical cabinet and a cable drum device. The device is applicable to overhauling, maintaining, washing and the like of a large-diameter cylinder body outer wall.

Description

technical field [0001] The invention relates to a lifting device, in particular to a climbing device capable of lifting and lowering outside the tower of a wind power generating set or the outer wall of a similar cylinder, which is used for users to repair, maintain and clean the outer wall of a large-diameter cylinder. Background technique [0002] In the prior art, when repairing, maintaining, and cleaning the outer wall of a large-diameter cylinder (such as the outer wall of a wind turbine tower), most of them fix one or two wire ropes on the top of the tower, and fix the lower end of the wire rope on the drum of the lifting platform. , using the motor and reducer to drive the reel, thereby driving the platform to lift. [0003] In the prior art, the climbing device that moves up and down along the large-diameter cylinder is as follows: figure 1 , 2 As shown, it is mainly composed of a roller 1, a reel 2, a reducer 3, a motor 4, a platform 5, and a wire rope 6. The rol...
