Helicopter tower positioning device

Abstract

The utility model discloses a helicopter vertical tower positioning device which comprises a main disc and a sub-disc, wherein the main disc and the sub-disc are both used for being fixed with a steelpipe, and the main disc and the sub-disc are provided with through holes, the main disc is provided with a positioning protrusion structure, the sub-disc is provided with a positioning hole, and thepositioning hole is used for being matched with the positioning protrusion structure. When the positioning protrusion structure is clamped in the positioning hole, the through holes in the sub-disc and the through holes in the main disc are stacked in a one-to-one correspondence mode to form a plurality of linear columnar spaces. The helicopter vertical tower positioning device has the advantagesthat in the installation process, after the positioning hole in the sub-disc of an upper module is aligned with the positioning protrusion structure on the main disc of a lower module, the main disc and the sub-disc can be clamped in place only by reducing the height of a helicopter, without front-rear and left-right adjustment of the hovering position, thereby greatly reducing the hovering time of the helicopter.

Description

technical field [0001] The invention relates to the field of iron tower equipment, in particular to a helicopter tower positioning device. Background technique [0002] At present, large and medium-sized iron towers (generally used for erecting transmission lines with a height of more than 60 meters) are mainly composed of steel pipes. Now the method of assembling the iron towers is as follows: the steel pipes are formed on the ground into several independent modules (often weighing several tons or even tens of tons), and then fix these independent modules one by one until all the modules are docked and fixed from bottom to top. [0003] There is a problem with this assembly method, because the iron tower is fixed and built from the bottom up by several independent modules. When the iron tower is built to a certain height, the uninstalled modules (referred to as upper modules in the industry) must be suspended by helicopters. Fix it to the installed module (referred to as t...

Problems solved by technology

[0003] There is a problem with this assembly method, because the iron tower is fixed and built from the bottom up by several independent modules. When the iron tower is built to a certain height, the uninstalled modules (referred to as upper modules in the industry) must be suspended by helicopters. Fix it to the installed module (referred to as the lower module in the industry), because the flange of the upper module and the flange of the lower module must be aligned one by one during the fixing process, only the flange of the upper module is aligned with the lower module. Only when the flanges on the module are aligned one by one, the bolt assembly can fix the upper module and the lower module together; therefore, the helicopter needs to continuously adjust the hovering position from front to back, left, and right during the process of suspending the upper module, and the entire suspension process is very time-consuming. To suspend and fix a module in calm weather, the helicopter must hover in the air for at least half an hour
