Description
Technical field
The present invention relates to a kind of power grid iron tower nut anti-thefts to tear composite structure and Anti-theft-dismounting method open, belong to power grid iron tower and its
Constructing technology field.
Background technique
Illegal obtain is stolen by criminal based on power grid iron tower and framework and other Important building facilities, metal building object
Benefit causes very big security risk to power grid iron tower and framework and other Important building facilities, and then influences power grid security and again
Want building facility stable operation.Existing anti-theft nut is clamped and can be screwed down from side with pipe wrench or spanner, cannot be fine
Play antitheft effect in ground.
Summary of the invention
Composite structure and Anti-theft-dismounting method are torn open it is an object of the present invention to provide a kind of power grid iron tower nut anti-theft, structure is simple,
It is at low cost, it is effectively prevented pipe wrench or spanner loose nut, guarantees power grid security and Important building facility stable operation, solves
The problem of background technique.
The technical scheme is that
A kind of power grid iron tower nut anti-theft tears composite structure open, includes nut, spanner and cylindrical cover, and cylindrical cover includes barrel and cylinder
Bottom, barrel are connected with cylinder bottom, and cylinder bottom is equipped with circular hole；Nut is cylindrical body, and centre is equipped with round bolt hole one, upper surface edge
Circumferencial direction is equipped with multiple sawtooth one, and sawtooth one is arranged from high to low along clockwise direction；The height of barrel is greater than the height of nut
Degree, nut are arranged in cylindrical cover；
Spanner includes driving end and spanner handle, and driving end is connected with spanner handle, and driving end is cylindrical body, and centre is equipped with round spiral shell
Bolt throughhole two, lower surface are along the circumferential direction equipped with sawtooth two, and sawtooth two matches with sawtooth one；The outer diameter of nut is greater than driving end
Outer diameter, less than the internal diameter of cylindrical cover；Round bolt hole two, round bolt hole one are connected with circular hole, and bolt is successively worn
Round bolt hole two, round bolt hole one and circular hole, bolts and nuts are crossed to be threadedly coupled.
The spanner handle quantity is two, is symmetricly set on the side surface of driving end.
The diameter of the circle bolt hole one is less than the diameter of round bolt hole two, the diameter of round bolt hole two
It is equal with the diameter of circular hole.
The sawtooth one and sawtooth two are right angled triangle sawtooth.
The cylindrical cover is columnar structured.
Present invention is mainly used for power grid iron tower and frameworks.Multiple sawtooth one are along the circumferential direction equipped in nut upper surface, are sawed
Tooth one is arranged from high to low along clockwise direction.Driving end lower surface is along the circumferential direction equipped with sawtooth two, sawtooth two and sawtooth one
Match, is engaged single direction rotation principle, fastening nut using sawtooth；If counter-rotating spanner, sawtooth two can only be made to skid off and stung
The sawtooth one of conjunction, cuts little ice to nut；Nut is placed in cylindrical cover, because barrel height is greater than the height of nut,
It cannot be reinforced with pipe wrench in nut, cylindrical cover can only be rotated, cylindrical cover original place, which is turn-taked, is unable to loose nut；It can be just inside cylindrical cover
The fastening dynamics of nut is not often influenced plus spring pad；The nut is removed, can only be removed using modes destructivenesses such as gas cuttings；Spanner
Handle quantity is two, can with the hands fastening nut, it is more labor-saving using more convenient；The diameter of round bolt hole two is slightly larger than
The outer diameter of the diameter of round bolt hole one, driving end is slightly less than the outer diameter of nut, and spanner is made not conflict with cylindrical cover generation.
A kind of power grid iron tower nut anti-theft tears the Anti-theft-dismounting method of composite structure open, using above-mentioned Anti-theft-dismounting composite structure, tool
Body comprises the following steps:
Cylindrical cover and nut are successively penetrated into bolt, the driving end of spanner is buckled on nut, and rotary spanner handle is engaged using sawtooth
Single direction rotation principle, nut is fastened in cylindrical cover；If when counter-rotating spanner, sawtooth two cannot be engaged sawtooth one, nothing
Method rotating nuts；Since the height of barrel is greater than the height of nut, nut outer diameter is less than cylindrical cover internal diameter, and nut is wrapped in cylinder
In shape cover, if rotated outside cylindrical cover with pipe wrench, cylindrical cover can only be rotated, loose nut is unable to.
Outdoor is arranged in power grid iron tower and framework for a long time, does not need replacement disassembly, is also less likely to be damaged, just carries out when discarding
Destructiveness is removed, and how to prevent robber from tearing open is urgent problem, and the present invention efficiently solves the problems, such as to tear open.
The beneficial effects of the present invention are: nut is arranged in cylindrical cover, can only be fastened with spanner；If counter-rotating
When spanner, cylindrical cover can only be rotated and cause empty rotation；Structure is simple, easy to use, at low cost, is effectively prevented spanner or pipe
Loose nut is clamped, guarantees power grid security and Important building facility stable operation.
