Manned platform suitable for installation of fan foundation anchor bolt assembly

Abstract

The invention discloses a manned platform suitable for installation of a fan foundation anchor bolt assembly, comprising a platform mechanism which is located at the center of the inner diameter of an upper anchor plate when in use; the bracket mechanisms are uniformly distributed and fixed on the platform mechanism at intervals; and the rigid safety guardrail mechanism is mounted on the platform mechanism. After the anchor bolts for positioning are installed on the lower anchor plate, the manned platform and the upper anchor plate are installed through the bracket mechanism, a crane lifts the manned platform and the upper anchor plate to the position over the lower anchor plate, the upper anchor plate and the anchor bolts for positioning are installed, and when other anchor bolts are installed, an operator is on the platform mechanism and under the protection of the rigid safety guardrail mechanism, and therefore the safety of the operator is guaranteed. Anchor bolts are installed at the same time from any face of the upper anchor plate at the straight or cross-shaped diagonal positions.

Description

technical field [0001] The invention relates to a manned platform suitable for installation of wind turbine foundation anchor bolt assemblies, and belongs to the technical field of wind turbine foundation installation. Background technique [0002] For the anchor bolt assembly that constitutes one of the foundations of wind power generators (referred to as wind turbines), it is necessary to install multiple anchor bolts on the upper and lower anchor plates that are vertically spaced, such as figure 1 shown. During installation, install the positioning anchor bolts on the lower anchor plate, lift the upper anchor plate to a certain height with a crane, and slowly move it to the top of the lower anchor plate, and the installer standing on the upper anchor plate will distribute the upper ends of the anchor bolts symmetrically Penetrate into the anchor hole of the upper anchor plate and screw on the temporary steel nut. After the positioning anchor bolts are installed and adju...

AI Technical Summary

Problems solved by technology

[0003] 1. During hoisting, the construction workers sat on the upper anchor plate, which violated the safety regulations of "no one is allowed on the hoisted object";

[0004] 2. During the whole process of construction work, construction workers can only sit on the upper anchor plate, which is completely empty inside, and the upper anchor plate is empty. The hanging point of the safety belt is more than 2m away from the plumb line of the hook, which is prone to falling and swinging Collision secondary injury;

[0005] 3. The construction workers sit on the upper anchor plate and place more than one hundred anchor bolts one by one, and adjust the level of the upper anchor plate, the concentricity of the upper and lower anchor plates, and the length value of the exposed anchor bolts. Exposure to high altitude for a long time On the edge, the security risk is extremely high;

[0006] 4. The installation area of ​​the anchor bolt assembly is densely populated and must be operated at the same time. There are cross operations between the two ends of the anchor bolt in the vertical space of the upper anchor plate and the lower anchor plate. security incident

[0007] In the Chinese patent publication number CN209277509U, the mobile scaffold used for fan prestressed anchor bolt installation, the staff can install the anchor bolt on the scaffold located on one side of the anchor bolt plate, which solves the above-mentioned problems of potential safety hazards, but, During the anchor bolt installation process, in order to prevent the overturning caused by the shift of the overall center of gravity, it must be installed at the same time in a straight or cross diagonal position. There is a problem that the scaffold needs to be moved frequently, and the surveyors will measure and adjust the upper anchor plate and the anchor plate in the later stage. When the concentricity of the lower anchor plate, the levelness of the upper anchor plate, and the length of the upper anchor plate are exposed from the upper end of the anchor bolt, there is also the problem that the scaffold needs to be moved frequently
