Description

Device for saving people and lowering cargo.

The device relates to rescue equipment and can be used in extreme evacuation of people and various objects from high-rise buildings during fires and natural disasters, as well as in everyday life in tourism, in construction and for launching cargo from a helicopter.

Known rescue sleeve for emergency descent (according to ed. St. J ol248607, IPC A 62 B 1/20 dated 11/20/1985 published on 07/07/1986 BI consisting of two elastic canvases, interconnected in the longitudinal direction by seams, along the entire length of which strips of inextensible material with color indication are inserted.

However, this rescue device has a limited range of use, since a rescue device made of elastic material is designed for vertical descent, which is most used in fires. This design is difficult to manufacture, since it is necessary to sew not only two elastic sleeves between each other, but also to sew strips of inextensible transparent material with color indication through equal promeshki. This device for descent provides for stationary mounting of the sleeve at the appropriate level; its floor of the building, and therefore has a weight limit. With a large weight of the evacuated body due to folds, there is no effective damping of speed. The cost of the rescue sleeve is quite high.

Closest to this device is a device for slowing down the fall of bodies (according to aBT.cB..hfe 980730 IPC A 62 B1 / 20 from 04/30/1981 published on 12/15/1982 BH.hfo46), containing two coaxially located and open from both ends of the sleeve, one of which is made of elastic material placed inside the rztsava of

inextensible material in a generous on Efavlesh, and both sleeves are interconnected by transverse seams.

The disadvantage of this device is that it is necessary to permanently fix each of the sleeves to the elements of a high-rise object, which is not always possible due to the design peculiarity of some objects. The inner folds of a sleeve that is inextensible in longitudinal section at the junction with the outer sleeve with a large mass of the evacuated body will create folds that can cause inconvenience when lowering a person, and when lowering a load, a jam can occur and create an inability to lower the voob e. An elastic sleeve provides only the correct position body during descent, i.e. there is a dependence of the descent speed on the shape of the descent body and its mass. All this limits the range of use of this device.

The basis of the proposed device is the task of creating a simple device for rescue; lift and lower cargo with a wide range of USES 1NII.

The stated task is corrected in that the device for saving people and lowering cargoes contains a sleeve with 3aiq) enameled top end from both ends, using three frames made of metal of rectangular cross section, connected by flexible connections, and the third frame is attached to one of the frames with the outer side of the opening with a hinge. In the longitudinal direction of the web, ropes are sewn that have a greater length than the sleeve located at an angle of inclination to the horizontal of descent at an angle of 35 degrees or less.

Use) Hose with ropes, the length of which is longer than the length of the sleeve allows you to manipulate and secure the sleeve in the lower part in the right and convenient place. Tension ropes can form

different cross-section, depending on their number, in the form of a rectangle when there are four, if more, then in the form of a polygon, which allows you to optimally adapt to the size and shape of the laden load. The sleeve, having an end from both ends of the end, provides free access of air, which is especially important when lowering people in fires. The safe angle of inclination of the sleeve relative to the horizontal of the descent is 35 degrees or less, defining a safe speed for lowering people and cargo. The design of the device includes the regulation of the speed of descent due to changes in the angle of inclination of the sleeve, there is no stationary fastening in the opening of buildings, which leads to an expansion of the range of use of the device during operation.

The upper end of the sleeve is secured with the help of three frames, two of which are mounted in the opening of the building, and the third is hinged at the bottom of the frame to set the angle of the sleeve and change its direction, depending on the need and place of application. Dte; frames connected by a flexible connection allow you to manipulate and set the desired degree of freedom when attaching to a building or other necessary place. The implementation of aluminum frames or another metal determines the strength of the fixing of the upper part of the sleeve in the opening. The device has a simple and technological design, which allows it to be used in various branches of smartphones, i.e. during the descent of cargo from helicopters, u) and the construction of various facilities, tourism and in the event of emergency situations, such as fires and natural disasters. At the same time, it is versatile, allowing it to be used for launching loads and people of various configurations and weights, while setting the speed of descent by the angle of the sleeve to the horizontal of descent. The design does not require stationary 1 heating, which allows you to quickly act in emergency situations, it is easy to assemble and fold. The design is technological, has a low cost, has not large dimensions and weight, does not require special conditions qpaHemw. All this allows you to use this device both individually and for widespread use for various needs.

In FigL shows a device for saving people and lowering cargoes, a general view; figure 2 - 1feping frames in the opening of the building.

The device comprises a sleeve 1, open at both ends, one of which is fixed in the joint of building 2 using frames 3,4,5, interconnected by flexible connections 6. The frames of the tf-corner section are fixed in the opening of building 2, one of which 1 is fixed to the other of frames on the outside of the opening 1 with the help of the scarf 7. In the longitudinal direction of the canvas, ropes 8 are sewn, having a longer length than sleeve 1, which is located at an angle to the horizontal of descent of 35 degrees or less.

The device operates as follows.

If it is necessary to evacuate people or cargo from any height in the service area of the device, one end of the sleeve 1 is thrown out and the other secured by the help of the frames in the opening of the building 2. The ropes 8, sewn in the longitudinal direction of the sleeve 1, are stretched by people standing below ( or with POMOPTS.Yu car) so that the angle of inclination with the horizontal is 35 degrees or less. The swivel connection 7 of one of the frames also sets the angle of the sleeve, which does not give distortions and provides the shape of the sleeve in the form of a tunnel of a certain shape. The cross-sectional shape is determined by the configuration of the frames and the number of ropes sewn into the web in the longitudinal direction. The optimal shape of the formed tunnel for rinsing is provided by the size of the frames in the form of a rectangle with sides of 1 m and 0.8 m and four ropes sewn into the sleeve in the longitudinal direction. Order

the descent of goods and people is uniform, at regular intervals. Depending on the size of the laden load and its shape, other sleeve sizes can be applied, i.e. the number of stitched ropes can change, which, when tensioned, form the desired shape. The angle of the sleeve, you can adjust the speed of descent depending on the mass of the laden load. The fabric for the sleeve should be light, durable and fireproof, for example, with a PVC coating.

The device for saving people and cargo with a simple design ensures reliability of the descent in any extreme situations, allows you to use for different needs of the national economy, i.e. during fires, in aviation, in construction and tourism. The device has a wide scope, has manufacturability and has a low cost.
