Abstract
The invention relates to a foot nail for preventing rope interference from falling. The anti-falling foot nail is composed of a common foot nail and an anti-falling foot nail, and is characterized in that: prevent weighing down the foot nail including installation dead lever (1), the one end of this installation dead lever (1) is passed through fastener demountable installation on power transmission tower, 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 this helix type pole (2) 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 (2) middle section. The invention solves the problem that a rope and the anti-falling pin rub or fall off from the anti-falling pin in the tower climbing operation process by improving the structural design of the existing anti-falling pin, and simultaneously solves the problem that the moment of a stress point of the anti-falling pin is overlarge.
Description
Technical Field
The invention relates to a foot nail for preventing rope interference from falling.
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.
Disclosure of Invention
The invention aims to provide a rope interference preventing falling pin which can effectively avoid the contact of human body parts on a rope and enhance the shock resistance of the falling pin.
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 invention solves the problem that a rope and the anti-falling pin rub or fall off from the anti-falling pin in the tower climbing operation process by improving the structural design of the existing anti-falling pin, and simultaneously solves the problem that the moment of a stress point of the anti-falling pin is overlarge. 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 spiral structure part of the anti-falling foot nail is closer to the main material of the iron tower, the force arm of a stress point is smaller, and the impact resistance of the anti-falling foot nail is effectively enhanced.

Detailed Description
As shown in fig. 3 and 4, the invention provides a rope interference preventing falling nail, which consists of a common nail and a falling nail, wherein the falling nail comprises an installation fixing rod 1, one end of the installation fixing rod 1 is detachably installed on a power transmission iron tower through a fastener, the other end of the installation fixing rod 1 is connected with a pedal rod 3 into a whole through a spiral line-shaped rod 2, the middle section of the spiral line-shaped rod 2 is in a spiral line shape, and a gap for a rope to pass through is arranged in the middle section of the spiral line-shaped rod 2 along the vertical direction.
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 using method and the working principle of the invention are as follows:
compared with the comparison document, the spiral structure part of the anti-falling foot nail is closer to the main material of the iron tower. When an operator climbs the tower, the safety rope is positioned between two hands and two legs of the operator, the rope passes through the chest of the operator, and the rope passes through the center of the spiral structure of the anti-falling foot nail and is limited by the left side and the right side respectively so as to be basically incapable of falling. 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. Meanwhile, the spiral structure part of the anti-falling foot nail is closer to the main material of the iron tower, so that the force arm of a stress point is smaller, the impact resistance of the anti-falling foot nail is effectively enhanced when the anti-falling foot nail accidentally falls, the deformation and damage of the foot nail are reduced, and the probability of breakage of the anti-falling foot nail is reduced.
