Description
Technical Field
The utility model relates to the technical field of anchor bolt hoisting, in particular to a wind power anchor bolt hoisting device.
Background
Wind power generation is an important clean energy supply mode, and the installation of the wind power generator needs a foundation with excellent mechanical properties, and one of the better choices at present is an anchor bolt foundation. The anchor bolt foundation adopts bolts to connect a plurality of anchor bolt rods with the upper anchor plate and the lower anchor plate into a whole, and has better shearing resistance and bending resistance because the whole stress is consistent. In order to improve the anti-corrosion performance of the anchor bolt foundation in the use process, so as to prolong the service life of the anchor bolt foundation, the current anchor bolt generally adopts dacromet coating to be oiled and greased, then a PVC sleeve or a PE sleeve is sleeved for corrosion prevention, and the sleeve is positioned in the middle of the anchor bolt.
In the splicing and installing process of the anchor bolt foundation, a plurality of anchor bolts need to be lifted one by one to be connected at the installation holes of the lower anchor plate by adopting lifting equipment, and as the whole anchor bolts are in a round rod shape, the lifting hook of the lifting equipment is difficult to directly lift the anchor bolts, so that the lifting mode adopted at present is as follows: the lifting hook and the anchor bolt are connected by using the lifting rope, specifically, one end of the lifting rope is hung on the lifting hook of the lifting device, and the other end of the lifting rope is wound and fixed on the outer surface of the anchor bolt, so that the fixed connection between the anchor bolt and the lifting hook of the lifting device is realized.
However, the prior art of the above-mentioned hoisting anchors has the following problems:
1. the sleeve is easily displaced: if the hoisting rope is wound and fixed at the end part of the anchor rod so as to realize the integral vertical hoisting of the anchor rod, the sleeve sleeved on the anchor rod easily slides downwards relative to the anchor rod under the action of self gravity, so that the sleeve deviates from the expected position; if twine the hoist and mount rope and fix on the sleeve pipe to realize holistic horizontal hoisting of crab-bolt, because hoist and mount rope is difficult to ligature at holistic focus position of crab-bolt, consequently the crab-bolt wholly takes place the slope easily in hoist and mount in-process, leads to the sleeve pipe still to slide for the stock easily, thereby deviates from the anticipated position.
2. The sleeve may be deformed or damaged: when the hoisting rope is directly bound and fixed on the sleeve, the hoisting rope can extrude the outer wall of the sleeve due to the gravity action of the whole anchor bolt in the hoisting process, so that the sleeve is deformed or even damaged, the expected use effect of protecting and corrosion preventing the anchor bolt by the sleeve is difficult to achieve, a new anchor bolt needs to be replaced, and the control of the construction cost is not facilitated.
3. Anchor bolt hoisting and lifting efficiency is low: the anchor bolts are fixed through on-site binding of the hoisting ropes to hoist and promote, binding is needed before hoisting, unbinding is needed after hoisting, and the hoisting promotion efficiency of the anchor bolts is low, so that the overall installation efficiency is low.
