Description

The invention relates to the field of fire equipment and is intended for carrying pressure hoses with a conditional pass from 25 to 65 mm and laying long hose lines consisting of several interconnected hoses.

It is known that the laying of hose lines for supplying extinguishing agents to a fire with the aim of localizing and extinguishing it is one of the main priority operational and tactical tasks of fire and rescue units. Often, due to the remoteness of the water supply sources or the inability to bring them closer to the burning area, it is necessary to lay rather long hose lines consisting of several pressure head fire hoses 20 m long each. Pressure head fire hoses are stored and transported in fire engines rolled up into slopes. When extinguishing fires, several slopes must be manually transferred over considerable distances. In this case, the following difficulties arise:

a sleeve rolled up into a roll is inconvenient to carry in a hand in terms of ergonomics;

the slide may weigh more than 12 kg depending on the diameter of the sleeve, which significantly affects the fireman’s performance when laying long hose lines;

in hands no more than two slides can be transferred at a time, hands are busy, which does not allow carrying other necessary fire equipment, for example a fire barrel;

when carrying sleeves in your hands to unwind the roll and lay the hose line, you have to roll the roll forward with a special movement, which is not always possible, for example, when laying hose lines up or over rough terrain.

In this regard, there is a practical need to facilitate the process of carrying fire hoses in a fire and laying hose lines with the ability to free the fireman’s hands and automatically deploy a hose fixed at one end to hydraulic equipment (pump, motor pump, hose branching) as it moves to the fire site.

There are various technical devices for carrying fire hoses of pressure head, made in the form of bags, into which a sleeve is folded or folded into an accordion (Japanese Patent 2004090807 of March 26, 2004, class 8A 62C 33/00; patent Sweden 7303320-1 from 09/06/1976, CL A62C 33/04; German patent 2312249 from 02/06/75, CL A62 C 33-04; French patent No. 532.733, publication date 02/10/1922, or in the roll (US patent 4,425,000 from 01/10/1984, class B65D 63/18, class US 294/165; 294/151; Swedish patent 469682 dated 08/23/1993 g, class A62C 33/04, B65H 75 / 34).

These devices have the following disadvantages:

1. They provide the convenience of carrying sleeves, but do not free the firefighter's hands.

2. Their design does not allow to unwind (unfold) the sleeve automatically when the fireman moves.

Known devices for tying the sleeves in a slope (Japan patent 2004180165 dated 06/17/2004, Japan patent 20033396231 dated November 26, 2003, class 7A 62C 33/00, class Japan 3713269 B2, UK patent 226.906 dated 8.01.1925 g .). These devices facilitate the carrying and transportation of sleeves in fire engines, preventing them from rolling out spontaneously, including under the influence of transport shaking. However, these devices also do not free the firefighter’s hands, and, in addition, devices patented in Japan are designed for hoses of only a certain diameter.

Special coils on wheels are known for which sleeves are wound. The coils are manually moved to the place of the fire, while the hose line, one end of which is attached to the pump of the fire truck, automatically unfolds (Pigolev S.V. “Fire Hoses”, ed. Of the Ministry of Agriculture of the RSFSR, 1952, 61 sec., Lyashuk R.G. . "Operation and repair of fire hoses", M., 1964, p.47).

The use of the described coils has the following disadvantages:

1. For their delivery to the place of fire requires a specially equipped car.

2. Coils have a relatively large mass and overall dimensions; when moving, the firefighter’s hands remain occupied.

3. The use of a coil is impossible, for example, for laying hose lines in the entrances of houses, various rooms of buildings and structures.

A device with two handles for carrying a hose roll is known, equipped with a rotating handle for winding and unwinding the roll with a hand (US patent 4,288,047 of September 8, 1981, class B65H 75/38, class US 242/86). There are rollers on the transverse axes for easier winding and winding of the sleeve. The device also does not free the firefighter’s hands during operations involving the laying of hose lines, and, in addition, the overall dimensions of the device are designed for hoses of a certain diameter. Manual rotation of the handle allows only one sleeve to be used by one person.

The closest analogue adopted for the prototype is a device for carrying and storing a fire hose (Canadian patent 2,733,024 from 01/31/1956). The device consists of two oblong frames articulated in one direction, made of a metal bar. On the end sides of the frames are freely rotating sleeves. A rope is attached to one of the frames.

A sleeve is wound on the sleeve of one of the frames. The second frame can either serve as a handle for carrying the sleeve, or lie on a roll so that the sleeve is evenly unwound and does not fall off the device. With the help of a rope, it is possible to hang two devices on the shoulders, freeing the firefighter's hands to carry other firefighting equipment, or additional rolling arms.

A sleeve connected at one end to hydraulic equipment when the fireman moves due to the free rotation of the sleeve automatically starts to unwind into a hose line.

The design of the prototype has the following disadvantages. When transferring the device on the shoulder, the roll in the radial direction becomes perpendicular to the human body, making it difficult for him to move, especially in a limited space and interfering with the freedom of hands (the diameter of the roll can reach 40 cm). The overall dimensions of the frames allow you to carry a sleeve of only one diameter.

The purpose of the present invention is to increase the efficiency and ease of operation when carrying pressure fire hoses and laying hose lines.

The present invention is directed to a device for carrying pressure fire hoses and laying hose lines, which would overcome the disadvantages of the prior art.

Figure 1 shows a device for carrying pressure fire hoses and laying hose lines, figure 2 is a section along aa.

The device (figure 1) consists of a mounting ring 1 with axles 2 located in the curly grooves of the handle 3 (figure 2), a removable portable belt 4, clamp 5. The mounting ring is made in the form of a short pipe having a groove 6.

The adjusting ring serves to accommodate the connecting head of the fire hose. The handle is used to carry the roll, as well as to fix the axes of the installation ring. The use of the device allows one fireman to transfer several skating rinks at the same time. The clamp protects against uncontrolled (random) rolling of the fire hose when laying the hose line.

The device works as follows:

a) Winding the sleeve.

The connecting head of the fire hose through the groove 6 (figure 1) is inserted into the installation ring 1 (figure 2). Next is the winding of the sleeve on the installation ring 1 (figure 1). Set the clamp 5 so that it grabs the last two turns of the sleeve and would be an emphasis on the edge of the handle (figure 2) with arbitrary rotation of the roll under the action of the mass of the connecting head (figure 1).

The winding of the sleeve can be done both with the handle removed and with it on. To remove the handle, it is necessary to simultaneously apply compression forces to the springy ends of the handle 3 and disengage the axis 2 of the adjusting ring 1 from it.

b) Unwinding.

Remove clamp 5 from the roll. Take the device by the handle or hang it on the belt and lay the hose line.

This goal of convenience in work when carrying pressure fire hoses is achieved by the fact that the device for carrying pressure fire hoses and laying hose lines (Fig. 1) contains a shoulder strap 4 connected to the frame 3 in the central part of its upper crossbar by a carabiner 7 that allows free rotation frame 3 around a vertical axis while wearing a shoulder strap. This design allows you to arrange the roll (the thickness of the roll depending on the diameter of the sleeve is not more than 10 cm) to the human body is more convenient and ergonomic. The sides of the frame are moved apart on the upper crossbar, which allows one frame to be used for carrying sleeves of various diameters.

Thus, when applying the invention, it is possible to release two hands of a firefighter, which allows assembly of a hose line when climbing a vertical ladder, which will eliminate injuries and increase safety measures in a fire.

At the same time overcoming blockages and laying the line, the supply time of fire extinguishing compounds is significantly reduced, which leads to an increase in the efficiency of the work of the gunmen.
