Abstract
The utility model discloses a kind of disposable wind turbine fastening bolts and the torque identification means of nut.It includes bolts and nuts, and by being arranged on the outside of bolt, one end is open and open end inner side edge along the first sheath of regular hexagon for being equipped with chamfer bevel and is set on the outside of nut and the blind end center of open end is corresponded on first sheath and set and be combined realization with the second sheath of the corresponding axially extending bore composition of covered nut.Due to taking the combination of sheath and wind power generating set fastening bolt and nut, and positioning mark is done in setting-out on sheath, every time during calibration, re-replace sheath, permanent identification line is drawn again, it just solves the problems, such as that clutter easily occurs in duplicate marking on bolt and nut in this way, fundamentally ensure that the accuracy of wind turbine fastening bolt and nut moment mark.Have many advantages, such as simultaneously simple and practical in structure, cost ineffective can it is high, easy for operation, suitable for popularization and application.
Description
Technical field
The utility model is related to a kind of torque identification means, more particularly, to be avoided that wind power generating set fastening bolt with
There are the torque identification means judged by accident in nut moment mark.
Background technology
To be related to the component of a variety of fastenings on wind-driven generator, in order to ensure the working performance of fastening effect and generator,
By the technological requirement of wind turbine, generally specific Tightening moment requirement, scene can be proposed with nut to the fastening bolt of different location
After operating personnel safeguard every time, positioning mark can be done with mark stroke lines in satisfactory fastening bolt and nut surface.
In order to ensure that fastening bolt meets the requirements with nut moment, provided in the service procedure of wind turbine, be in certain time interval, profit
With dedicated torque spanner to thering is the fastening bolt of Tightening moment requirement and nut to carry out torque calibration, when generation moment variations
When, the position of fastening bolt and nut is readjusted, and stamp mark again.
After multiple mark, fastening bolt the situation for having multigroup mark simultaneously, operating personnel will occur with nut surface
During customary inspection, by the mark on fastening bolt and nut surface, when going to determine whether to loosen, it is possible that
The situation of two kinds of erroneous judgements, when one kind is the practical torque deviation without generation, the result for occurring judging by accident is exactly to do a power again again
Square is calibrated, but actually this is a unnecessary transition torque calibration behavior；Another kind is that torque deviation actually occur, but
It is mistaken for torque to still conform to require, thus will appear torque and do not meet standard technology requirement, there are potential quality safety is hidden
Suffer from.It may lead to irregular operating or the major accident of wind-driven generator when serious.
Invention content
The utility model lies in that providing a kind of disposable wind turbine fastening bolt and the torque identification means of nut, mainly it is
After solution multiple mark in the prior art, fastening bolt will appear multigroup mark with nut surface, easily judge by accident
Situation, so that wasting time and resource or there are problems that potential security-hidden trouble.So that it is guaranteed that fastening bolt and nut
The accuracy of torque mark.
The technical solution of the utility model is as described below：It includes bolts and nuts, mainly by bolt outer sheath
If one end is open and open end inner side edge along the first sheath of regular hexagon for being equipped with chamfer bevel and is set on the outside of nut simultaneously
The blind end center that open end is corresponded on first sheath sets second formed with covering the corresponding axially extending bore of nut
Sheath is combined realization.
Structure of the utility model due to taking first sheath of regular hexagon, the second sheath, and by itself and wind-force
Generating set fastening bolt is organically combined with nut, i.e., a hexagon sheath is added on fastening bolt, nut, and in sheath
Positioning mark is done in upper setting-out, every time during calibration, is re-replaced sheath, then draw permanent identification line, can thus be solved in spiral shell
The problem of clutter that bolt easily occurs with duplicate marking on nut, fundamentally ensures the accuracy of wind turbine Tightening moment mark
And reliably realize goal of the invention.There is simple and practical in structure, cost ineffective high, easy for operation, suitable can promote simultaneously should
The advantages that using.

Specific embodiment
The disposable wind turbine fastening bolt of the utility model and the torque identification means of nut, are explored in production practices
The novel product structure of invention.It was not only simple in structure but also economical and practical.And set is devised according to the fastening means of bolts and nuts
The first sheath of regular hexagon being located on the outside of bolt（Such as Fig. 1-Fig. 3）2 and nut on the outside of the second sheath of regular hexagon（As Fig. 4-
Fig. 6）4.First sheath 2, the second sheath 4 one end be open, and in open end inner side edge along setting chamfer bevel 1.Institute
It states the second sheath 4 and 2 shape of the first sheath is essentially identical, except that being set at the center with the corresponding blind end in open end
There is an axially extending bore 3.The axially extending bore 3 is corresponding with covered nut.Polyethylene can be used in first sheath 2, the second sheath 4
Or polypropylene material makes.For ease of use, in design, along suitable chamfering is selected, described first protects inner side edge sheath
Cover 4 open end inner side edge of the 2, second sheath along chamfer bevel 1 for 45-60 ° in order to install and replace, present embodiment selection
45°.Occur coming off and being conveniently replaceable in use in order to prevent simultaneously, first sheath 2, the second sheath 4 and bolt,
Nut bound fraction selects light Interference size cooperation.
The use of the utility model：It is with special torque spanner, by wind turbine technique parameter request to different location first
Fastening bolt, nut carry out Tightening moment calibration, after reaching standard torque requirement, stop；Then bolt or nut fastening side are pressed
Formula, the first sheath 2 for selecting no through-hole respectively or the second sheath 4 for having through-hole are sleeved on the corresponding bolt or nut for having calibrated torque
On；A fixed position is selected in Fan Equipment, carrying out corresponding positioning datum with marking pen identifies, then in the first sheath 2 or
Positioning datum point is directed on second sheath 4 and draws positioning mark two-wire（As shown in Figure 7）；It was found that after offset, mark has been removed
The first sheath 2 or the second sheath 4 known repeat aforesaid operations.After calibrating every time, new sheath is all taken, is done again
Positioning mark, can thus solve the problems, such as that the operating personnel caused by repeatedly identifying coincidence or confusion can not accurately identify.
Take that the utility model carries out disposable wind turbine fastening bolt and the torque of nut identifies, easy to operate, cost is minimum, have compared with
Good operability and economy.It is suitble to promote and apply.
