Description

The invention relates to devices for testing rescue equipment (rescue ropes up to 30 and 50 meters, hose delays) and equipment (fire belts and carbines).

A device for testing rescue equipment and equipment is known. (Yu.F. Yakovenko, A.I. Zaitsev, L.M. Kuznetsov et al. Handbook “Operation of fire fighting equipment.” - M.: Stroyizdat, 1991, p. 392, Fig. 63).

Taken as a prototype. The prototype, like the claimed device, is intended for testing rescue equipment and firefighters equipment. The prototype, in contrast to the presented solution, has a more complex technical solution. The design of the prototype is more complex and metal-consuming. The design uses an electric drive. The disadvantages of the prototype are the large size and weight, the need to connect to electricity. Great cost of the product.

The author was faced with the task of creating an inexpensive, easy to manufacture and reliable in operation device for testing rescue equipment and firefighter equipment:

1. rescue ropes up to 30 meters;

2. rescue ropes up to 50 meters;

3. sleeve delays;

4. fire zones;

5. fire rifles.

To solve this problem, the design of the test device was applied using a certified and proven dynamometer and a certified manual winch. The device for testing rescue equipment (life ropes up to 30 and 50 meters, hose delays) and firefighters equipment (fire belts and carbines) consists of a main device in the form of a pipe with a diameter of at least 300 millimeters with removable fastenings to the surface of FIG. 1 (item 1, sheet 1) and FIG. 6 (item 1, sheet 4) and two separate mounts for engaging a hand winch and a dynamometer, one of which is designed to test life ropes 30 and 50 meters long, and the second - to test fire belts, carbines and hose delays - FIG. 1 (item 2, sheet 1) and FIG. 6 (item 19, sheet 4).

Using this device, 2 workplaces are used for testing:

1. Testing of life ropes 30 and 50 meters long;

2. Test firefighter belt, fireman’s carbine and hose delay.

On sheet 1 (Fig. 1) shows a test circuit using a manual winch and a dynamometer rescue rope with a length of 30 and 50 meters.

On sheet 4 (Fig. 6) shows a diagram of the test belt of the fireman, fireman’s carbine and hose delay.

From the diagrams it is seen that 2 work directions are used and, accordingly, 2 workplaces from the main device for testing:

1. Parallel to the mounting of the main device - for testing life-saving ropes 30 and 50 meters long (Fig. 1, sheet 1);

2. Perpendicular to the mounting of the main device - for testing fire belts and carbines, hose delays (Fig. 6, sheet 4).

In both working directions, a certified manual winch, a certified and verified dynamometer, 2 separate fasteners (one for each working direction - to engage the rescue rope, manual winch or dynamometer) are used - FIG. 1 (item 2, sheet 1); FIG. 6 (item 19, sheet 4).

The main device for testing (Fig. 1, pos. 1, sheet 1) is shown on sheet 2 (Fig. 2, view A and Fig. 3, view B).

The main device consists of a metal pipe with a diameter of at least 300 mm (pos. 3, Fig. 2, 3), 2 vertical scarves (pos. 4, Fig. 2, 3), 2 horizontal scarves (pos. 5, Fig. 2, 3), fastening a pipe with a metal sheet by means of welds (pos. 6, Fig. 2, 3) for fastening to the wall using chemical anchors (pos. 7, Fig. 2, 3). Inside the pipe are fastened 2 U-shaped channels (pos. 8, Figs. 2, 3), which are connected using a metal rod (pos. 9, Figs. 2, 3), with a roller located in the middle (pos. 10, Fig. 2, 3). On one of the channels there is an eyelet for hooking the rescue rope (pos. 11, Figs. 2, 3).

A separate mount for testing the life-saving ropes (FIG. 1, item 2, sheet 1) is shown on sheet 3 (FIG. 4, view B and FIG. 5, view D).

FIG. 4 (view B, sheet 3) and FIG. 5 (view D, sheet 3) - a separate fastening for testing life-saving ropes 30 and 50 meters long, consisting of a base plate (pos. 12, Fig. 4, 5), a small base plate (pos. 13, Fig. 4, 5 ), a square metal rod (pos. 14, Fig. 4, 5) made of 2 corners using welds, 2 fastenings - Eyelet (pos. 15, Fig. 4, 5), fixed to a metal rod through the holes using a nut connection, a scarf (pos. 16, Figs. 4, 5), designed to reinforce stiffness at the point of attachment of a square metal rod to a small base plate. The base plate is attached to the wall (floor) using chemical anchors (pos. 17, Figs. 4, 5). The base plate and the small base plate are connected using 4 studs and a nut connection (pos. 18, Figs. 4, 5). A small base plate, a square metal rod and a scarf are connected by welds.

A separate mount for testing fire belts, carbines and hose delays (FIG. 6, item 19) is shown on sheet 4 (FIG. 7, view D and FIG. 8, view E).

The mount consists of a metal sheet (pos. 20, Fig. 7, 8), 1 mount in the form of an eye (pos. 21, Fig. 7, 8), 1 corner (pos. 22, Fig. 7, 8). The metal sheet is attached to the wall using a chemical anchor (key 23, FIG. 7, 8). The corner is attached to the sheet with a weld. The ear is fixed to the corner with a weld.

Advantages of the above construction.

Easy to manufacture and operate. It does not require a 220 or 380 volt electrical network, as a prototype. Small in size and weight. It can be used both indoors and outdoors. Easily removed from the installation site. It can be used both in a vertical position (main wall, partition, etc.) and in a horizontal position (floor, asphalt concrete pavement, etc.).

Serve (install, dismantle) and perform tests can 1 employee. All welds can be replaced with bolted joints. All dimensions indicated in the above construction are not fundamental and may vary, with the exception of the size of the pipe diameter - at least 300 mm (Order of the Ministry of Emergencies No. 630 of 12/31/2002). In addition, it is possible to test life-saving ropes and more than 50 meters provided that a separate fastening is placed to test life-saving ropes to the distance necessary from the main device.

Disclosure and implementation of the invention.

The first essential feature sufficient to achieve the above technical result is the versatility of this design. With the help of one design, at least 5 items of fire-rescue equipment and fire-fighting equipment can be tested.

The second significant feature is the presence of 4 independent locations (including mount and roller) on the main device for testing in 2 directions. All places are independent of each other and do not interfere even with simultaneous testing.

The third essential feature is mobility, that is, the movement of all elements of the invention when the test site is changed (transportation from one unit to another for testing).

The fourth essential sign may be the complete or partial collapsibility of the structure during dismantling. This condition can be observed when replacing welds with a bolted joint of structural components. This feature is necessary for quick dismantling, transportation and installation at a new test site.

The fifth essential sign can be fixing both in a vertical position (main wall, partition, etc.) and in a horizontal position (floor, asphalt concrete pavement, etc.).

The device operates as follows.

Test the rescue rope L = 30 m (Fig. 1, sheet 1). By the eye of the main structure of FIG. 1 (pos. 1, sheet 1) with the help of a fire carbine, the end of the rescue rope (through the thimble) is fixed.

The rope is full length. The other end is attached to the winch. The winch is attached to a dynamometer, which is attached to the eyelet of a separate mounting of FIG. 1 (pos. 2, sheet 1) (there is no fundamental difference in the location of the dynamometer in front of or after the winch). By means of a manual winch, the tension required for the test is achieved. According to the regulatory document, in this case - the Order of the Ministry of Emergency Situations No. 630 dated December 31, 2012 of Appendix No. 3 - 350 kg. The load is held for 5 minutes. After unloading, there should be no damage to the rescue rope; the residual elongation should not exceed 5%.

Test the rescue rope L = 50 m (Fig. 1, sheet 1).

By the eyelet of the separate fastening of FIG. 1 (pos. 2, sheet 1) with the help of a fire carbine, the end of the rescue rope is fixed through the thimble. The rope dissolves to its full length through the roller of the main structure of FIG. 1 (item 1, sheet 1). The other end is attached to the winch. The winch is attached to the dynamometer, which is attached to the second eyelet of a separate mounting of FIG. 1 (pos. 2, sheet 1) (there is no fundamental difference in the location of the dynamometer in front of or after the winch). By means of a manual winch, the tension required for the test is achieved. According to the regulatory document, in this case - the Order of the Ministry of Emergency Situations No. 630 dated December 31, 2012 of Appendix No. 3 - 350 kg. The load is held for 5 minutes. After unloading, there should be no damage to the rescue rope; the residual elongation should not exceed 5%.

For testing, the belt is worn on a metal pipe of the basic structure of FIG. 6 (item 1, sheet 4) with a diameter of at least 300 mm and fastens with a buckle. A hand winch is attached to the carabiner mounted on the half ring of the belt, to which a dynamometer is attached. The dynamometer is fixed to the eyelet of the separate fastening of FIG. 6 (item 19, sheet 4). By means of a manual winch, the tension required for the test is achieved. According to the regulatory document, in this case - the Order of the Ministry of Emergency Situations No. 630 dated December 31, 2012 of Appendix No. 3 - 350 kg. The load is held for 5 minutes. After removing the load, the belt should not have any breaks or other damage to the belt tape, buckles, rivets, etc. The carbine should not have a changed shape and integrity of the material. The carabiner bolt should open freely and close tightly.

Test sleeve delay (Fig. 6, sheet 4).

For testing, the delay is hooked to the inner surface of the metal pipe of the main structure on the opposite side of the roller of FIG. 6 and on the buttoned loop of the fire carbine to the hand winch to which the dynamometer is attached. The dynamometer is fixed to the eyelet of the separate fastening of FIG. 6 (item 19, sheet 4). By means of a manual winch, the tension required for the test is achieved. According to the regulatory document, in this case - the Order of the Ministry of Emergency Situations No. 630 dated December 31, 2012 of Appendix No. 3 - 200 kg. The load is held for 5 minutes. After removing the load, the sleeve delay hook should not be deformed, and the braid should not have breaks or other damage.
