Description

Prevent rope interference's anti-falling foot nail

Technical Field

The utility model relates to a prevent that rope interferes prevents weighing down foot nail.

Background

In the electric power operation maintenance industry, maintenance personnel often need to carry out tower climbing maintenance operation, various types of safety protection measures are often equipped on a power transmission tower in order to protect the safety of the tower climbing maintenance operation personnel, and anti-falling foot nails are one of the measures. The existing anti-falling foot nail generally consists of a mounting and fixing structure part, a foot pedal structure part and a spiral bending structure part, and the prior anti-falling foot nail is shown in figure 1. When in use, the anti-falling foot nails are arranged on the main material of the power transmission tower and are matched with the common foot nails left and right on the main material of the tower, so that the operating personnel can conveniently grab and step on the tower by hands and feet when climbing the tower, see figure 2. In the use process, the safety rope is connected with the safety belt on the body of an operator, the operator winds the safety rope into the rotary center of the spiral structure of the anti-falling foot nail through the spiral bending part of the anti-falling foot nail in the tower climbing process, and when the operator falls accidentally, the spiral part of the anti-falling foot nail can provide a safe anti-falling hanging point for the operator, so that the aim of preventing falling accidents is fulfilled.

However, in the actual application process on site, the anti-falling foot nail spiral structure part is far away from the main material of the iron tower, the feet, the legs and the body of a worker climbing the tower are positioned between the safety rope and the main material of the iron tower, and the legs and the body of the worker can continuously touch the safety rope in the tower climbing process, so that the rope swings. The swinging of the rope not only aggravates the friction between the rope and the anti-falling pin, but also easily causes the rope to accidentally fall off from the spiral structure of the anti-falling pin due to the swinging, thereby causing the serious consequence of failure of the anti-falling safety protection. In addition, when falling occurs, the stress point of the anti-falling foot nail is arranged on the spiral structure part, the stress working condition of the anti-falling foot nail is a cantilever structure, the moment is large, and the foot nail is easy to deform and damage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent that rope interferes prevents weighing down foot nail can effectively avoid the touching of people's health position to the rope to the reinforcing prevents weighing down the shock resistance of foot nail.

The utility model provides a prevent that rope interferes prevents weighing down foot nail comprises a ordinary foot nail and a weighing down foot nail, its characterized in that: prevent weighing down the foot nail including the installation dead lever, the one end of this installation dead lever is passed through fastener demountable installation on steel pylons, and the other end of this installation dead lever links into an integrated entity through helix type pole and step pole, and this helix type pole middle section is the helix shape, is equipped with the clearance that supplies the rope to pass through along the vertical direction in this helix type pole middle section.

Wherein the surface of the foot bar is rough or an anti-skid layer is covered on the foot bar.

The common foot nail consists of an installation fixing rod and a foot rest rod which are connected into a whole, and one end of the installation fixing rod is detachably installed on the power transmission iron tower through a fastener.

The utility model discloses an improve the current structural design who prevents weighing down the foot nail, solved and stepped on the tower operation in-process rope and prevent weighing down the foot nail friction or from preventing weighing down the problem that the foot nail deviates from, solve simultaneously and prevent weighing down the too big problem of moment of foot nail stress point. The method also has the following advantages: 1) the rope can be effectively prevented from being touched by the body part of a person, so that the swinging of the rope is reduced, and the rope is prevented from falling off the anti-falling foot nails due to the swinging; 2) the utility model discloses it is closer to iron tower principal material to prevent weighing down the helical structure part of foot nail, and the arm of force of stress point is littleer, has effectively strengthened the shock resistance who prevents weighing down the foot nail.

Detailed Description

As shown in fig. 3 and 4, the utility model provides a prevent rope interference prevent weighing down foot nail comprises a ordinary foot nail and a prevent weighing down foot nail, prevent weighing down the foot nail including installation dead lever 1, fastener demountable installation is passed through on power transmission tower to the one end of this installation dead lever 1, and the other end of this installation dead lever 1 links into an integrated entity through helix type pole 2 and

step pole

3, and 2 middle sections of this helix type pole are the helix shape, are equipped with the clearance that supplies the rope to pass through along the vertical direction in 2 middle sections of this helix type pole.

Wherein the surface of the pedal rod 3 is rough or the pedal rod 3 is covered with an anti-skid layer, wherein the common foot nail consists of an installation fixing rod 1 and the pedal rod 3 which are connected into a whole, one end of the installation fixing rod 1 is detachably arranged on the power transmission iron tower through a fastener, and the fixing rod and the pedal rod 3 are the same as the anti-falling foot nail.

The utility model discloses a use method and theory of operation are:

compared with a comparison file, the utility model discloses well prevent weighing down the helical structure part of foot nail and be closer apart from iron tower owner material. When the operating personnel climbs the tower, the safety rope is located between two hands and two legs of the operating personnel, the rope passes from the chest of the operating personnel, and then the utility model discloses thereby prevent weighing down the helical structure center of foot nail and pass the back by left and right spacing basically can't drop respectively. The operating personnel is at the tower-climbing in-process, and positions such as hand, foot, leg, health generally all can move to the outside, places the rope in the intermediate position, can effectively avoid the touching of people's health position to the rope to reduce the swing of rope and the spacing of helical structure center has further reduced the probability of droing. And simultaneously, because the utility model discloses in prevent weighing down the helical structure part of foot nail more closely apart from iron tower main material, consequently the arm of force of stress point is littleer, has effectively strengthened preventing weighing down the shock resistance of foot nail when accidentally falling, has reduced the deformation and the damage of foot nail, has reduced and has prevented weighing down the cracked probability of foot nail.
