Antitheft foundation bolt for iron tower and application method of antitheft foundation bolt

Abstract

The invention discloses an antitheft foundation bolt for an iron tower and an application method of the antitheft foundation bolt, and relates to the technical field of iron tower protection equipment. The antitheft foundation bolt comprises a pre-buried portion, a screw fixedly connected to the pre-buried portion and a fastening nut in threaded connection to the screw. A radial hole formed on theperipheral face of the screw is arranged on the side, away from the pre-buried portion, of the fastening nut. A conic pin with one end extending out of the radial hole is inserted in the radial hole.The end, extending out of the radial hole, of the conic pin can prevent a foundation nut from being screwed out. A limiting hole is arranged at the end, inserted in the radial hole, of the conic pin.An axial hole capable of communicating with the limiting hole is formed at the outer end of the screw. An axial pin is contained in the axial hole, wherein when the axial pin is inserted into the limiting hole, the tail end of the axial pin is flushed with the tail end of the screw. The problems that in the prior art, an antitheft foundation bolt is low in antitheft effect, complex in structure and inconvenient to machine are solved; and the antitheft foundation bolt has the advantages that antitheft is achieved, the structure is simple, the foundation nut can be fastened many times on the basis of achieving antitheft, quantization checking and accepting are achieved, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of iron tower protection equipment, in particular to an anti-theft anchor bolt for an iron tower and a method for using the same. Background technique [0002] Anti-theft bolts are anti-disassembly bolts. The existing anti-theft bolts generally bury the screw rods of the anchor bolts on the ground, tighten the fastening nuts, and then smash the upper end of the screw rods with a hammer or other equipment, thereby destroying the upper thread of the screw rods. , so that the fastening nut cannot be disassembled, but the use of this anti-theft bolt has poor standardization in the anti-theft process, cannot be quantified for inspection and acceptance, and the operation is extensive, and it causes artificial damage to the top of the anchor bolt. [0003] Existing can refer to the Chinese utility model patent that authorized announcement number is CN2282088Y, and it discloses a kind of anti-theft bolt. It include...

AI Technical Summary

Problems solved by technology

[0008] The above-mentioned anti-theft bolts used in the iron tower equipped with anti-theft bolts can not only solve the problem of nut loosening but also achieve the effect of preventing nut disassembly, but the internal structure of the above-mentioned screw is relatively complicated, and the overall size of the screw is generally small, so In actual production and processing, there is a problem that it is not easy to complete the processing and manufacturing of the above-mentioned screws.
