Description
Technical Field
The invention relates to a fan foundation anchor bolt fast-assembling system, and belongs to the technical field of fan installation construction.
Background
When the anchor bolt of the wind driven generator anchor bolt assembly is installed on land, the existing general method is to use a crane to lift the upper anchor plate, so that the gravity of the upper anchor plate is completely borne by the lifting hook, 1-2 workers go up to the upper anchor plate with the height of about 4m from the ground, the anchor bolt with the length of about 4m is erected by manpower by 2-3 workers on the ground, the anchor bolt penetrates through the anchor bolt hole on the side of the upper anchor plate firstly, then penetrates through the anchor bolt hole on the lower anchor plate, and finally the nuts at the upper anchor plate and the lower anchor plate are locked. Taking a certain project of golden wind 3.0MW wind generating set as an example, the total number of foundation anchor bolts is 176, which means that in the installation of the anchor bolts, the process of more than 176 times needs to be repeated, and the problems of large labor consumption and low efficiency exist. When workers of the upper anchor plate and the lower anchor plate work, the workers of the upper anchor plate can only sit on the upper anchor plate, the inner part of the upper anchor plate is totally empty, the width of the anchor plate is only 0.5m, and although a safety belt can be hung on a crane hook, the distance between a safety belt hanging point and a hook plumb line is more than 2m, once the safety belt falls, swinging collision can occur, larger secondary damage is caused, and the problem of large potential safety hazard exists; when workers work, the workers who go up the anchor plates and go down the anchor plates still have the safety risk of vertical crossing operation, and safety accidents such as people injury due to falling objects, falling from high places, mechanical striking and the like are very easy to happen.
In chinese patent publication No. CN209277509U, although the worker can install anchor bolts on the lower anchor plate and the lower anchor plate through the scaffold, the problem of potential safety hazard in the operation of the worker on the upper anchor plate is solved, however, the worker can occupy one working face of the anchor bolt assembly in the installation, and cannot simultaneously operate around the periphery, when the installation of the adjustment and replacement working face is performed, the scaffold needs to be moved by self-locking rollers many times, and the construction efficiency is reduced.
