Description

Technical Field

[0001] The invention relates to the technical field of protection of high-altitude suspended assembly precision control tooling, in particular to a protection component used for high-altitude suspended assembly precision control tooling. Background Art

[0002] The high-altitude suspension method is a cantilever construction method. It uses a mobile suspension crane to lift the prefabricated beam segment to the bridge position, and then uses epoxy resin glue and prestressed steel wire bundles to connect them into a whole. It is assembled segment by segment. After one segment is tensioned and anchored, the next segment is assembled. The segmentation of the cantilever assembly is mainly determined by the lifting capacity of the suspension crane. If the segment is too long, it is heavy and requires a suspension crane with a large lifting capacity. If the segment is too short, there will be many assembly joints and the construction period will be extended.

[0003] The existing high-altitude suspended splicing method requires the use of splicing precision control tooling to control the splicing precision during the suspended splicing. The splicing precision control tooling usually uses a level. The level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the leveling measurement principle.

[0004] The lens of the current level has no protective structure, which causes the lens of the level to be damaged when the level is used for high-altitude suspension precision control or when the level is taken away, thereby rendering the level unusable. Summary of the invention

[0005] The purpose of the present invention is to provide a protective component for high-altitude suspended precision control tooling to solve the problem that the leveling instrument lens is easily damaged.

Then, through the cooperation of the protective guiding rod and the protective guiding groove, the protective cover plate is pulled outwards. When the protective cover plate contacts the rotating holding block, the rotating holding block is pressed into the rotating holding groove through the inclined surface of the rotating holding block until the rotating holding spring holds the rotating holding block into the protective limiting groove, thereby limiting the rotation of the protective cover plate. Then, the protective cover plate is turned downwards, and the protective cover plate covers the lens end, thereby protecting the lens and effectively preventing the lens from being damaged during the taking process.
