Abstract
The invention relates to an anti-loosening wind power bus connecting component which comprises two tubular conductors to be connected, a connector and a flexible coupling. The bottom of the anti-loosening wind power bus connecting component is provided with a connection plane which is welded with the connector to form a whole. The flexible coupling is fixedly connected with the connector through a bolt. The bolt is connected with a locknut. The anti-loosening wind power bus connecting component is firmer in locking, capable of effectively preventing the bolt from loosening, safer, and capable of greatly improving work efficiency.
Description
Technical field
The present invention relates to a kind of tubular wind power bus connecting elements for wind power plant.
Background technology
In wind power plant, in order to improve the current capacity of bus, can adopt tubular conductor as wind power bus, but the wind power bus of tubular conductor is due to its circular cross section, make the connection of two sections of buses more difficult, existing tubular bus joint exists complex structure, the defects such as inconvenience is installed, and the vibrations that the wind power bus after installing produces owing to using, due to its junction use is common bolt and packing ring, easily loosening, even come off, thereby the potential safety hazard of causing affects operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of anti-loose wind power bus connecting elements for above drawback, and its locking is more firm, can effectively stop bolt looseness, safer, has greatly improved operating efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of anti-loose wind power bus connecting elements, comprise two sections of tubular conductors to be connected, joint and being flexible coupling, and its bottom has one to connect plane, described connection plane is welded into an integral body by welding and joint, described being flexible coupling is fixedly connected with joint by bolt, wherein, described bolt is connected with stop nut, described stop nut inner surface is provided with internal thread, described internal thread is provided with the first tooth and the second tooth, the cross sectional shape of the first described tooth is isosceles trapezoid, the cross sectional shape of the second tooth is isosceles triangle, the drift angle γ of the isosceles triangle that described the second tooth is is 120 °, base angle δ is 30 °, the externally threaded cusp of described bolt withstands on the second tooth of stop nut.
Above-mentioned a kind of anti-loose wind power bus connecting elements, wherein, between described bolt and joint, be provided with lock washer, described lock washer is comprised of a pair of pad, described pad is hollow circle structure, the occlusal surface of described pad and noncontact face are provided with the sawtooth of divergent shape, sawtooth quantity on described noncontact face is greater than the sawtooth quantity on described occlusal surface, serration depth on described noncontact face is less than the serration depth on described occlusal surface, and described two pads are by integral body of the intermeshing formation of the sawtooth on occlusal surface.
Above-mentioned a kind of anti-loose wind power bus connecting elements, wherein, the angle [alpha] of the occlusal surface sawtooth of the pad of described lock washer is greater than the lead angle β of described bolt
Beneficial effect of the present invention is:
1. stop nut inner surface is provided with internal thread, described internal thread is provided with the first tooth and the second tooth, the isosceles triangle that the second tooth is, when bolt and stop nut are tightened mutually, the cusp of bolt has just withstood on the second tooth of stop nut tightly, make to be applied to the normal force that screw thread Contact produces and become 60 ° of angles with bolt axis, and unlike plain bolt, become 30 ° of angles, make its normal pressure be far longer than fastening pressure, therefore, the locking frictional force producing also increases greatly, therefore greatly increased the coupling mechanism force of bolts and nuts, even can not get loose voluntarily in violent vibrations yet, greatly improved security performance.Meanwhile, when bolt external screw thread and nut inner thread interlock, load is evenly distributed on contact-making surface, has extended useful life.
2. between bolt and joint, be provided with lock washer, lock washer is by the intermeshing composition of sawtooth of a pair of pad, the angle [alpha] of the occlusal surface sawtooth of pad is greater than the lead angle β of described bolt, guaranteed that bolt can be good at being locked on joint, can keep very high chucking power, greatly improve locking effect, can effectively stop bolt looseness, and by using the instrument of standard just can efficiently mount and dismount easily, and do not affect secondary assembling, do not use.
3. two of pad surfaces are equipped with sawtooth, and its load-carrying ability is increased greatly.
