Large and medium sized tower column outer wall mobile climbing frame

Abstract

The invention provides a large and medium sized tower column outer wall mobile climbing frame and belongs to the technical field of carrying. The large and medium sized tower column outer wall mobile climbing frame is characterized by comprising an upper frame (1), an upper left clamp (21), an upper right clamp (18), a lower frame (7), a lower left clamp (12) and a lower right clamp (15), wherein the upper left clamp (21) and the upper right clamp (18) are connected with the upper frame (1), the lower left clamp (12) and the lower right clamp (15) are connected with the lower frame (7), and the upper frame (1) and the lower frame (7) are connected through a connecting rod (4) to form a whole. Three electric motors (5, 22 and 11) can respectively drive three screws (4, 20 and 14) to rotate at the right moment, control the upper frame (1), the lower frame (7) and all the clamps and enable the frame to perform extensible movement like an inchworm a little and hold a tower column (23) to climb or descend, and left-hand threads and right-hand threads are respectively arranged at two ends of each screw. The upper layer and the lower layer of the frame clamp the large tower column so as to achieve vertical climbing, is very stable, does not shake and is high in working efficiency and low in cost, and especially the safety is remarkably improved.

Description

technical field [0001] The invention relates to a mechanical device capable of transporting workers and objects to high-altitude operations next to large and medium-sized tower columns, and belongs to the field of transport technology. Background technique [0002] In order to maintain and repair the blades of large-scale wind turbines, the main method currently adopted is to use a large crane or lower a steel rope from the top of the wind turbine tower to hoist a basket containing people and objects to the side of the blades. This method has the following disadvantages: Lanzi lift is complex and unstable at high altitude, it is very easy to shake, the operation is not smooth, the work efficiency is low, the cost is high, especially the safety is poor, and it is daunting. In order to protect the environment, the global clean energy industry, especially the emerging wind power industry, has entered a stage of rapid development since the beginning of this century. In 2013, the...
