Description

The utility model relates to equipment for rescuers of the Ministry of Emergencies and can be used to organize lifeguard insurance on the sloping icy roof of buildings and structures.

Known safety (sleeve) delay containing a metal hook and attached to it a flexible power element in the form of a closed loop (http://www.prof-shop.ru/antipozhar/index.php?cat=219) (figure 1). The known device is used when working on fires and is included in the mandatory list of fire-technical weapons (PTV). The device is intended for fastening in case of fire fire hoses and vertical water supply hose lines to the building structure or to the steps of high-altitude staircases.

The disadvantages of the known safety delay is that its design solves the problem of securing the hose line, but does not provide for the need to insure the partner against the possibility of falling and falling from a height.

Based on the specific task of retaining the static weight of the water column, the hose delay is calculated and checked once a year with a load of 200 kgf for 5 minutes.

The technical result, the achievement of which the present utility model is aimed, is to increase the safety of the lifeguard when working on the sloping icy roof of buildings during fires and emergencies by quickly organizing insurance in the right place and at the right time while maintaining the possibility of fixing the hose line.

The specified technical result is achieved due to the fact that in the safety delay of the rescuer of the Ministry of Emergencies for organizing lifeguard insurance on the sloping icy roof of buildings and structures containing a metal hook and a flexible power element attached in the form of a closed loop, according to a utility model, the neck of the hook has a flat shock a surface located at an angle of 20-30 degrees to the horizontal plane drawn through the top of the neck of the hook, and the inner surface of the hook profile is made with a diameter of 35-36 mm, p and this hook profile, the location and angle of inclination of the playing surface are configured to provide penetration of the roof of the building during the impact on the flat surface of the hook.

In addition, the specified technical result is achieved due to the fact that the hook can be made of hardened steel, and the loop is made by weaving from

heat-resistant aramid fibers of the Kevlar, Armos type.

A safety delay can be placed in the case.

The inner profile of the hook can be made with a diameter of 35-36 mm.

The design of the safety delay is illustrated by drawings, where:

figure 1 shows a typical well-known sleeve delay, in which a rope is tied with a loop;

figure 2 shows the profile of the hook indicating the impact surface;

figure 3 shows the hook assembly with a heat-resistant high-strength loop;

figure 4 shows a hook 1 with a loop 2, hammered into the roof 3 with a safety carabiner fastened to the loop and a safety rope 4 fastened into the carabiner;

figure 5 shows a variant of use as a sleeve delay;

figure 6 shows the placement of the cover with a safety delay on the belt of the fireman.

The safety delay of the rescuer of the Ministry of Emergencies for the organization of lifeguard insurance on the sloping icy roof of buildings and structures contains a metal hook 1 and a flexible power element 2 attached to it in the form of a closed loop. The back of the hook 1 has a flat impact surface A, while the profile of the hook 1, the location and the angle of inclination of the impact surface A are configured to penetrate the roof 3 of the building upon impact on the flat surface A of hook 1. The optimal angle of inclination of the impact surface of a horizontal plane drawn through the top of the nape of the hook is 20-30 degrees.

To ensure the strength and heat resistance necessary for safe insurance, hook 1 is made of hardened steel, and the loop is braided from heat-resistant aramid fibers of the Kevlar, Armos type.

For ease of use, a safety delay is placed in a belt cover.

The implementation of the internal profile of the hook 1 with a diameter of 35-36 mm makes it possible to use the product as a sleeve delay.

Using the proposed safety delay allows you to quickly organize the necessary lifeguard insurance in case of a threat to life when working on the sloping icy roof of buildings during fires and emergencies in the right place at the right time. As a basis for calculating the strength, we take the data that the permissible dynamic load on the lifeguard during disruption and free fall is 300 kgf when working with a firefighter’s belt and up to 600 kgf when working in a system with loops and shoulder straps.

Hook safety delay (figure 2) is calculated on a load of at least 1500 kgf

made of 6 mm high-strength hardened steel sheet with a hardness of 32-38 H Rc, the neck of the hook has a flat striking surface A, along which is driven. A high-strength heat-resistant aramid fiber loop, also designed for a load of at least 1,500 kgf, is tied into the hole of the hook ear (figure 3).

The rescue delay works as follows:

The tip of the hook 1 is placed perpendicular to the roof 3. On a flat surface A located on the back of the head, the hook 1 is hit, for example, with the ax of a firefighter rescuer.

The shape of the hook, the location of the hook tip and its geometry allow punching the sheet metal of the roof and the wooden crate anywhere (Fig. 4), after which the lifeguard fastens the climbing carabiner into the high-strength loop and, if life threatens, provides a partner's insurance against falling from a height using a safety 4 ropes and techniques from the arsenal of climbing equipment.

A climbing carabiner fastened into a loop, having a normative guaranteed strength of at least 2200 kgf, allows you to organize dynamic partner insurance using a safety rope and techniques from the arsenal of climbing equipment.

The inner surface of the hook profile is made with a diameter of 35-36 mm, which allows it to be hung on the step of the ladder and used as a sleeve delay (figure 5).

For ease of use, a safety delay with a loop is placed in a case for carrying on a belt (Fig.6).

Thus, the use of the proposed safety delay allows for the efficient organization of the necessary lifeguard insurance in case of a threat to life when working on the sloping icy roof of buildings during fires and emergencies in the right place and at the right time.
