Description

The utility model relates to the field of ensuring safety of work at heights in the communications industry, energy, and specifically, to the device of a nozzle for the upper part of the ladder to prevent the upper part of the ladder from shifting during its use with the anchor point to ensure the safety of work at heights, which mainly It can be used with a ladder for climbing wooden, metal and reinforced concrete supports of overhead communication lines and power lines.

There is a known principle of securing a flexible anchor point to the supports, proposed on the Russian market by a number of companies offering safety systems for work at heights. In particular, this device is offered by SAFE-TEK (http://www.safe-tec.ru/products/zakhvaty/ Flexible anchor lines).

The closest technical solution is the nozzle for supporting the KRAUSE pole / mast, made of a rectangular metal profile, along the edges of which there are adjustable clamps for attaching the nozzle to the ladder. Two grips under the support are fixed on a rectangular profile, which can be adjusted horizontally depending on the diameter (size) of the support. (see the KRAUSE online store of ladders in the section "Accessories, ferrules for supports and spare parts" at http://krause-shop.ru/product/nasadka-dlja-opory-na-stolbmachtu-krause-122452). The KRAUSE pole / mast nozzle is designed to securely attach stairs with rungs to columns with a diameter of 100–250 mm, and can be used on stairs with an internal width of 300–400 mm.

In accordance with applicable labor protection regulations, safety systems must be used when performing work at heights. The safety system consists of:

a) an anchor device;

b) harness (safety harness, for holding, for positioning, for sitting position);

c) a connecting-damping subsystem (slings, ropes, carabiners, a fall protection device of a slide type on a flexible or rigid anchor line).

 The upper part of the support of overhead communication lines and overhead power lines of VLE in the Russian Federation is not equipped with rigid anchor points for attaching safety systems. At present, fastening of safety systems is possible using flexible anchor points or special hooks. The principle of installing flexible anchor lines on the upper end of the support inherently has a subjective assessment of strength characteristics, which can affect the safety of work.

The objective of the proposed utility model is to increase safety at altitude.

The essence of the utility model lies in the fact that the nozzle on the ladder with an anchor point, including a base made of a rectangular metal profile, at the edges of which there are adjustable clamps for attaching the nozzle to the ladder, grips under the support are fixed on the rectangular profile, which are adjustable horizontally depending from the diameter of the support, in addition, two eyelets are installed on each grip for fixing the anchor loop passing through the eyelets of the grips and having plastic thimbles at both ends Flexible flexible anchor line.

The technical result in ensuring the safety of work at height when climbing and working on the stairs is achieved due to the fact that on each grip of the nozzle there are two eyes for fixing the anchor loop. An anchor loop passes through the eyelets of the grips, which creates an anchor point on the upper part of the ladder for attaching protection from falling from a height.

The utility model is illustrated in the drawing, where Fig. 1 shows a general view of a nozzle on a ladder with an anchor point.

The nozzle on the ladder with the anchor point consists of a metal rectangular profile 1, on the edges of which there are adjustable clamps for attaching the nozzle to the ladder, consisting of an arm 2 with a slot for adjusting the clamp, a G-shaped screw 3 and a wing nut 4. On a rectangular profile clamps 5 are fixed under the support, which can be adjusted horizontally depending on the diameter (size) of the support, which are fixed with a screw from the wing 6. On each capture 5 there are two eyes for fixing the anchor loop. An eye at the base of the grip 7 and an eye at the end of the grip 8. An anchor loop 9 passes through the eyes of the grips 7 and 8, which has plastic thimbles 10 at both ends for attaching a flexible anchor line with a slider type of protection (grip).

 The device operates as follows. The nozzle on the stairs with an anchor point is installed on the upper edge of the stairs. Using the L-shaped screw 3 and the wing nut 4, the nozzle is attached to the sides of the stairs. A ladder with a nozzle is brought to the support on which it is planned to climb. The nozzle rests on a support at the level of a person’s chest. Around the support, through the eyes, an anchor loop is worn. For thimbles 10 of anchor loop 9, a flexible anchor line and a means of protection (grip) of the slide type are fastened through the carabiner. A ladder with a nozzle and an anchor loop 9 rises to the required height. Set in a stable position. A flexible anchor line is manually pulled. Thus, the anchor loop 9 is fixed to the support and creates an anchor point on the top of the stairs. The nozzle is attracted to the support motionless, thereby further preventing the movement of the upper part of the ladder during its use. The lower end of the anchor line is tied to the lower step of the ladder. Before climbing the stairs, a man puts on a safety harness and fastens through a carabiner for a means of protection (capture) of a slide type. During lifting, the gripper moves along a flexible anchor line with a person who is connected to the anchor point on the nozzle. In the case of a person falling from a ladder, under the influence of his gravity, the anchor loop 9 through a flexible anchor line and a means of protection (gripping) of the slide type keeps him from falling from the ladder. Thus, during the ascent along the entire length of the stairs, a person is constantly insured against falling from a height at each unit of time. This ensures the safety of work at height when climbing and working on the stairs.
