Problems solved by technology
At present, the installation of blade bolts and nuts is mainly done manually, but the diameter of the bolt hole is larger than the diameter of the bolt. The nut can rotate in the nut hole, and the bolt can move in the chord direction in the bolt hole. There is no guarantee that the bolt verticality of each bolt meets the design requirements

Embodiment Construction
[0033] The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
[0034] A wind turbine blade root bolt verticality control tooling, please refer to Figure 1~Figure 5 , the bolt 1 is a stud bolt, and the bolt includes a smooth small diameter section 102 located in the middle and a large diameter threaded section located at both ends; The rubber sleeve 2, the two-half metal sleeve 4, and the two sleeve locking rings 3 threadedly connected to the outer surfaces of the two ends of the metal sleeve 4 respectively. The inner diameter of the rubber sleeve 2 is the same as that o...

The invention discloses a tool for controlling the verticality of a bolt at the root of a wind power blade and a method for installing the bolt. The tool includes, from the inside to the outside, a rubber sleeve with two halves arranged concentrically, a metal sleeve with two halves, and Two casing locking rings respectively screwed to the outer surfaces of the two ends of the metal casing; the inner diameter of the rubber casing matches the outer diameter of the smooth small diameter section in the bolt, and the outer diameter of the rubber casing matches the metal casing. The outer diameter of the metal casing is 0.5mm smaller than the inner diameter of the bolt hole at the root of the wind turbine blade, and the inner diameter of the casing locking ring is larger than the outer diameter of the large diameter section of the thread. By inserting the metal casing into the root of the wind turbine blade in parallel In order to ensure the verticality of the bolt passing through the rubber sleeve when it is connected to the bolt hole. The tooling can ensure that the bolts are perpendicular to the end face of the root of the wind turbine blade, thereby avoiding the problem of large vertical deviation of the bolts that may occur during the installation of the bolts at the root of the wind turbine blade.
Description
technical field [0001] The invention relates to the technical field of auxiliary tooling for assembling a wind power blade bolt system, in particular to a tool for controlling the verticality of a bolt at the root of a wind power blade and a bolt installation method. Background technique [0002] Fiberglass wind turbine blades are one of the key components of wind turbines, which are connected to the hub through a certain root connection. The most common blade root connection method is "T bolt connection". This design requires special drilling equipment to drill bolt holes and nut holes at the blade root after the blade is demolded, and then install the bolts and nuts into the bolt holes. Connect to the nut hole. In order to ensure that the blade bolts can be well connected to the pitch bearing of the wind turbine, it is necessary to ensure that the blade bolts are perpendicular to the end face of the blade, and the design tolerance is usually 0.2°. The bolts used on wind ...
