Rag bolt protector

Technical Field

The utility model relates to a protection technology field especially relates to a rag bolt protector

Background

With the rapid development of the communication, power, broadcast television and other industries, the demand for iron towers serving as supports for antenna equipment is increasing. Most of the iron towers are connected with a foundation by adopting foundation bolts, and the foundation bolts are exposed outside and are easy to rust or artificially damaged. The existing common protection method is to use concrete for encapsulation, and the method has the defects that the encapsulation quality is difficult to control, for example, the encapsulation is not compact or has cracks, rainwater can infiltrate, and anchor bolts are easy to rust. Once the condition occurs, the detection is difficult, and the accident potential is easy to cause. If the regular detection is carried out, the original encapsulation needs to be destroyed, which is time-consuming, labor-consuming and high in cost.

For another example, patent application No. CN201220096487.4 discloses a protective cover, and more particularly, to a protective cover for an anchor bolt. The anti-corrosion screw cap comprises a cap body, anti-corrosion grease, a nut protection body and a screw protection body, wherein the cap body is composed of the nut protection body and the screw protection body, the nut protection body and the screw protection body are integrally formed, the cap body is filled with the anti-corrosion grease, the nut protection body and the screw protection body are of a hollow structure, the screw protection body is arranged above the nut protection body, and threads are arranged on the inner wall of the screw protection body. The foundation bolt protective cover is simple, compact and reasonable in structure, convenient and fast to assemble and reliable in connection, can ensure that the foundation bolt is used for a long time in a severe environment, prolongs the service life of the foundation bolt, reduces the maintenance cost of the foundation bolt, and is easy to use and popularize.

But neither of the two shields can intuitively reflect whether the foundation bolt is loosened or not.

Drawings

Fig. 1 is a schematic structural diagram of the device of the present invention.

Fig. 2 is a cross-sectional view of the device a-a of the present invention.

The drawing marks comprise 100 parts of a cover body, 110 parts of a large pipe, 120 parts of a small pipe, 130 parts of transition sections, 111 parts of annular concave-convex grooves, 112 parts of round holes, 113 parts of bending parts, 200 parts of transverse partition plates, 210 parts of threaded holes, 300 parts of a base, 400 parts of nuts and 500 parts of foundation bolts.

Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

The device comprises a cover body 100 and a transverse clapboard 200, wherein the cover body 100 is arranged on a base 300, the transverse clapboard 200 is arranged in the cover body 100 and is connected with the cover body 100, the cover body 100 consists of a large pipe 110, a small pipe 120 and a transition section 130, the upper end of the small pipe 120 is a hemispheroid, the lower end of the small pipe is an open cylinder, the large pipe 110 is connected with the small pipe 110 through the transition section 130, the transition section 130 is in a circular truncated cone shape, the junction of the large pipe 110, the small pipe 120 and the transition section 130 is in circular arc transition, the transition section 130 is used for positioning the transverse clapboard 200, the lower end of the large pipe 110 is provided with a circumferential concave-convex groove 111 for detecting whether an anchor bolt 500 is loosened or not, a circular hole 112 is arranged on the pipe wall of the large pipe 110 and is used for fixing the transverse clapboard 200, the bottom end of the large pipe 110 is provided with a bending part 113 which can enable the, for fixing the anchor bolt 500.

During installation, the device is screwed on an anchor bolt 500 needing protection through a threaded hole 210 in the diaphragm plate 200 until the bottom of the cover body 100 is attached to the base 300, a gap exists between the lower surface of the diaphragm plate 200 and the upper surface of the nut 400 at the moment, and a gap also exists between the top surface of the cover body 100 and the top surface of the anchor bolt 500.

Under the normal fixed condition of nut 400, the pressure that is applyed by base 300 is born by nut 400 completely, protector is in the normal condition of not atress, when nut 400 is not hard up, upwards displacement will be produced through base 300 of rag bolt 500 fastening, because protector and diaphragm 200's rigidity, cover body 100 lower part will receive pressure this moment to the annular tongue and groove 111 department of cover body 100 lower extreme will take place to warp, consequently through the deformation condition of the annular tongue and groove 111 of cover body 100 lower part, can reflect whether nut 400 is not hard up promptly, thereby play the monitoring effect, simultaneously the inside enclosure space that forms of protector can make rag bolt 500 and nut 400 have rust-resistant and anti-destruction effect.

Further, the large tube 110, the transition section 130, and the small tube 120 are any polygonal body.

Further, the top of the small tube 120 is any polygonal body.

Further, the cross section of the bulkhead 200 is an arbitrary polygon.

Further, the number of the nuts 400 is 2 or more than 2, so that the anchor bolts 500 can be more firmly fixed.

Further, the circular hole 112 and the diaphragm 200 are fixed by welding.

The above is not a limitation to the technical solution of the present invention, and any obvious substitution is within the protection scope of the present invention without departing from the inventive concept of the present invention.
