Abstract
The utility model discloses an anti-loosing identification device for wind power generator set bolts. The utility model comprises a hollow column, a hollow regular hexagon-shaped column and a disc. The hollow column, the hollow regular hexagon-shaped column and the disc are wholly cast and molded at one time. The hollow column is arranged over the hollow regular hexagon-shaped column and the disc is disposed under the regular hexagon-shaped column. The utility model is characterized in that an identification hole having a certain width is disposed at one side of the hollow regular hexagon-shaped column, and the upper part and the lower part of the identification hole respectively extends to the hollow column and the disc. The device of the utility model enables on-site working personnel to rapidly and effectively finish anti-loosing identification operation on the bolts such that anti-loosing identification is uniform in shape, consistent in direction and standard in appearance.
Description
Technical field:
The utility model relates to and is used for wind power generating set screw retention identity device, relates in particular to a kind of locking identity device that is used for the wind power generating set high-strength bolt.
Background technique:
Continual renovation along with the wind power generation field technology, the type of wind power generating set is by 600kW, capacity such as 750kW develop into the above big capacity of MW class, the wind power generating set electric motor power also is being explosive growth, unit tower tube connects, being connected between tower tube and the engine room foundation, being connected between engine room foundation and the wheel hub, being connected or the like between wheel hub and the blade, all be to adopt the high-strength bolt Placement, every unit on average all has four or five hundred high-strength bolts to guarantee the operation that unit safety is stable, in addition, also has yaw motor, gear-box, the connecting bolt that generator etc. are located.
Numerous connecting bolt like this on the wind power generating set, when every half a year, annual maintenance, all to inspect by random samples, even full inspection, whenever, checked a bolt, and all will do a locking mark of maintenance, purpose has two, the one, write down the bolt of having checked, the 2nd, can judge easily by this mark whether bolt is loosening.At present, the site operation personnel adopt marking pen, draw locking mark by hand on bolt and nut, there are a lot of defectives in this mode, as identify unclear, connect incomplete, crooked, not enough standard etc., not only influence the attractive in appearance of blower fan, and it is lack of standardization to construct, and is difficult to identification, causes the potential safety hazard of wind-powered electricity generation unit operation, so this screw retention identification means is carried out technological improvement, be very necessary and significant.
This device can also be applied in all mechanical devices or mechanical system that use high-strength bolt except being applicable to wind power generating set screw retention sign, and Applicable scope is very extensive.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of wind power generating set screw retention identity device, comprise hollow circuit cylinder, hollow regular hexagon post and disk, hollow circuit cylinder, hollow regular hexagon post and disk are that one piece is injection molded, hollow circuit cylinder is positioned at the top of hollow regular hexagon post, disk is positioned at the bottom of hollow regular hexagon post, it is characterized in that, open a sign hole 4 with certain width on one side along hollow regular hexagon post, sign hole 4 extends to hollow circuit cylinder and disk up and down.
In the said apparatus, sign hole 4 can be bar shaped, triangle, geometrical shape such as trapezoidal.
In the said apparatus, sign hole 4 is along the median vertical line opening of hollow regular hexagon post.
In the said apparatus, the hole pitch in sign hole 4 is between 1mm to 5mm.
In the said apparatus, can adopt discontinuous hatch frame between three parts in upper, middle and lower in sign hole 4.
In the said apparatus, add a circle circular baffle plate at the outward edge of disk.
In the said apparatus, at hollow circuit cylinder top mounting knob.
The utility model device can guarantee that field personnel's screw retention of finishing rapidly and efficiently identifies, and accomplishes that locking sign shape is unified, direction is consistent, standard attractive in appearance.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing 1 is the stereogram of the utility model wind-driven generator screw retention identity device;
Accompanying drawing 2 is plan views of the utility model wind-driven generator screw retention identity device;
Accompanying drawing 3 is plan views of the utility model wind-driven generator screw retention identity device.
Embodiment:
With reference to Fig. 1, Fig. 2, the utility model wind-powered electricity generation unit screw retention identity device comprises hollow circuit cylinder 1, hollow regular hexagon post 2, disk 3, hollow circuit cylinder 1 is used to entangle bolt column, and hollow regular hexagon post 2 is used to entangle nut, and disk 3 is used to be close to flanged surface.
Along the sign hole 4 that the median vertical line on hollow regular hexagon post 2 arbitrary limits is opened an about 2mm of width, and extend to hollow circuit cylinder, lower disk respectively up and down, promptly three parts in upper, middle and lower are all opened a sign hole 4 in same vertical plane.
By the utility model device, when constructing at the scene,, aim at above-mentioned seam with spray paint can and spray once as long as this device is enclosed within on the tagged bolt of needs, can stay straight locking clearly sign on bolt, nut and the flange.
The width in sign hole 4 is determined according to the clearness of bolt specification and sign in the utility model device, can be according to actual conditions, and the A/F in designated identification hole 4, the opening of different in width will produce the locking sign of different clearness.
In order to increase the mechanical strength of this device, can adopt discontinuous hatch frame between the sign hole 4 of three parts in upper, middle and lower.
The utility model device also has another mode of execution, except having hollow circuit cylinder, hollow regular hexagon post, disk, can add a circle circular baffle plate, the flange of making dirty when avoiding spraying paint at the outward edge of disk.
The utility model device also has another mode of execution, installs handle additional at the hollow circuit cylinder top, and handle is positioned at the hollow circuit cylinder top, makes things convenient for the user to take.
The utility model device size, size and shape can be according to the standard respective production of screw bolt and nut, to adapt to the bolt of different size.
