In the power system, in order to mount the transmission tower or pole tower, usually when constructing the iron tower or pole tower, foot nails are installed to facilitate the operator to get up and down. In the prior art, the foot nails are mostly designed from the perspectives of anti-skid, anti-freeze, and safety handles.

The Chinese patent "anti-deformation high-strength foot nail" with the authorization announcement number CN203948020U includes a foot nail body, an anti-fall cap, a pair of fixing nuts and a number of anti-skid ribs. The cross section of the foot nail body is circular, and one end is provided with an external thread. The other end is bent obliquely upward, the anti-fall cap is arranged on the obliquely upwardly bent end of the foot nail body, the anti-slip rib is arranged on the upper surface of the foot nail body, and the foot is fixed by the pair of fixing nuts. The nail body is arranged on the iron tower, a rectangular positioning groove is arranged under the foot nail body, and a reinforcing plate is also included. The reinforcing plate is composed of a fixing plate and a supporting plate, and the fixing plate is arranged on the fixing nut and the iron tower between, the support plate is arranged on the fixing plate, the fixing plate is further provided with perforations, the support plate is triangular in shape, and has a space for the slot, and the upper surface of the support plate is in the shape of a wedge and One end away from the fixing plate is a high place. Although this patent adds a reinforcing plate, it also has the following defects: as we all know, the cross-sectional diameter of the foot nail body is relatively small, and a positioning groove is arranged under the foot nail body, and the support strength of the foot nail body at the positioning groove is undoubtedly significantly reduced. Moreover, the connection between the positioning groove and the support plate should also make the position of the positioning groove and the support plate relatively fixed, otherwise, the installation cannot be performed smoothly.

Therefore, how to solve the above problems has become the focus of research by those in the field.

Please refer to FIG. 1 to FIG. 4 . As shown, this embodiment provides an improved support structure for an anti-falling foot nail, which includes a foot nail body 1 , a reinforcing member 2 , a first nut 3 , and a second nut 4 , a first gasket 5 and a second gasket 6, the reinforcement 2 includes a support part 201 and a fixed part 202, the support part 201 and the fixed part 202 are connected by connecting ribs 203 and integrally formed into a regular quadrangular pyramid structure , the support part 201 and the fixed part 202 are square table bodies, the center of the support part 201 and the fixed part 202 is processed with a coaxial support hole 204, one end of the foot nail body 1 is provided with an external thread section 101, and the other One end is provided with an upwardly curved arc-shaped section 102, and the external thread section 101 sequentially passes through the support hole 204 on the support part 201, the first nut 3, the first gasket 5, the support hole 204 of the fixed part 202, and the transmission tower. Or the pole tower 7, the second washer 6 and the second nut 5, by adjusting the first nut 3 and the second nut 4, the foot nail body 1 and the support member 2 are fixed on the transmission tower or the pole tower 7, in order to increase the support member 2. For the support strength, the fixing part 2 can be further fixed to the transmission tower or the pole tower 7 by using screws, and the end of the arc-shaped section 102 is welded with the anti-skid cap 8 .

It can be seen from the above structure that the foot nail body 1 can greatly enhance the supporting strength of the foot nail body 1 under the action of the support member 2, and when the foot nail body 1 and the support member 2 are installed together, only the foot nail body 1 needs to be penetrated. After the supporting hole 204 on the supporting member 2 is formed, it can be fixed on the transmission tower or the pole tower 7 by nuts, and the installation is convenient and simple.

In order to strengthen the double tack, commonly known as the pig's trotter buckle, when it is fixed on the foot nail body, it is more difficult to slip, the anti-skid cap 8 is welded with barbs 9, and a number of anti-skid ribs 10 are integrally formed on the surface of the arc section.

It has been found in multiple impact tests that if the inner hole of the first nut 3 is a fully threaded structure, when the first nut 3 is threaded to the joint of the external thread section 101 and the arc section 102, it is easy to cause the joint to bend. deformation. Therefore, in the present invention, half of the inner hole of the first nut 3 is provided with internal threads, and the other half is unthreaded. The threaded end does not pass the junction of the external thread segment 101 and the arcuate segment 102, and experiments have proved that the junction can be effectively prevented from bending deformation.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
