Description

inflatable ropeway

technical field

The invention relates to the technical field of cableway marine lifesaving equipment, in particular to an inflatable cableway on water.

Background technique

At present, the life-saving equipment that is often used in the rescue of a shipwreck by passing ships includes a life buoy, a life jacket or a lifeboat. In the rescue process, the rescued personnel are required to equip themselves with the aforementioned equipment and then go down into the water and then swim or paddle to a safe boat. However, general shipwrecks often occur due to strong winds and waves brought by bad weather. It is very dangerous for the crew of a shipwrecked ship to jump into the sea when the wind is strong and the waves are strong. Many weak people lost their precious lives because they could not fight the wind and waves. Among the waves.

Therefore, it is particularly urgent to develop a kind of life-saving equipment that can make the rescued personnel not jump into the sea and can easily reach the rescue ship to be rescued when rescue.

Contents of the invention

The technical problem to be solved by the present invention is to propose a life-saving equipment that can prevent the crew from entering the water and easily reach the rescue ship when rescuing the distressed crew.

The technical solution proposed by the present invention to solve the above-mentioned technical problems is: an inflatable cableway, including a strip-shaped inflatable cushion, a cable and a sling. The cables include a pair of upper cables and a pair of lower cables located on and below the strip-shaped inflatable cushion and arranged symmetrically along the length direction of the strip-shaped inflatable cushion. The first connection is formed, and the two ends of the sling are respectively connected with a pair of upper cables to form a second connection. The sling is U-shaped and the bottom of the U-shape is tightly hooped on the bottom surface of the strip-shaped inflatable cushion. The lower cable The upper cable and the upper cable can move along the length direction of the strip-shaped inflatable cushion at the first connection point and the second connection point respectively.

The beneficial effects of the present invention are:

Through the present invention, a cableway can be built between the rescue ship and the wrecked ship, and the rescued personnel can quickly and safely pass through the cableway in the present invention without entering into the water for swimming, which improves the survival rate of the weak. When there is a height difference in the cableway between the two ships, the rescued personnel can also glide on the cableway.

The perfection and improvement of the above-mentioned technical solutions include:

In order to prevent the cables and slings from wearing each other, the inflatable cableway in the present invention includes a cylindrical sliding sleeve, the cylindrical sliding sleeve has an axial hole and a radial groove, the lower cable is passed through the axial hole, the The junction of the sling and the lower cable is wound in the radial groove.

In order to improve the buoyancy of the cableway in the water in the present invention: the strip-shaped inflatable cushion is composed of three left, middle and right airbags connected side by side, and connecting straps are provided at the two connections of the airbags, and the through holes are opened in Attach the belt.

In order to improve the safety of personnel when passing the cableway in the present invention, a safety net is provided between the upper cable and the strip-shaped inflatable cushion. In order to prevent the sling from pulling the through hole on the strip-shaped inflatable cushion, the edge of the through hole is provided with a grommet.

Detailed ways

Example

The inflatable cableway in the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, comprises a pair of upper cables 1, a pair of lower cables 2, an elongated air cushion, a sling 3 and a columnar sliding sleeve 5.

Among them, the two ends of a pair of upper cables 1 and a pair of lower cables 2 are tensioned and then anchored. The length direction of the inflatable cushion is arranged symmetrically. The strip-shaped inflatable cushion is placed on the tight lower cable 2, the lateral sides of the strip-shaped inflatable cushion are provided with through holes for the sling 3 to pass through, and the edges of the through-hole are provided with buttonholes. The strip-shaped inflatable cushion is composed of three left airbags 4.1, middle airbag 4.2 and right airbag 4.3 connected side by side. The joints between the left airbag 4.1 and the middle airbag 4.2, the middle airbag 4.2 and the right airbag 4.3 are respectively provided with connecting belts, through holes It is set on the connection belt.

As shown in FIG. 4 , the cylindrical sliding sleeve 5 has an axial hole and a radial groove, and the lower cable 2 is passed through the axial hole. The sling 3 passes through the through hole to respectively form a first connection with a pair of lower cables 2 , and the rope body at the joint between the sling 3 and the lower cables 2 is wound in the radial groove.

The two ends of the sling 3 are respectively provided with a ferrule 2.1 made of cable body flower arrangement, the ferrule 2.1 is set on the upper cable 1, and the two ends of the sling 3 respectively form a second connection with a pair of upper cables 1, and the sling is U-shaped and its U-shaped bottom is tightly hooped on the bottom surface of the strip-shaped inflatable cushion.

The lower cable 2 and the upper cable 1 can move along the length direction of the elongated inflatable cushion at the first connection point and the second connection point respectively.

A safety net is provided between the upper cable 1 and the strip-shaped inflatable cushion.

When assembling, the two ends of the upper cable 1 and the lower cable 2 are anchored to the rescue ship and the ship in distress respectively, and are tensioned by tensioning equipment (such as hydraulic winches), and a certain amount of tension is left after tensioning. safety margin. Then, after the cables are tensioned, the strip-shaped inflatable cushion is inflated to finally form the inflatable cableway that can be used for water rescue in the present invention.

The present invention is not limited to the above-mentioned embodiments, and all technical solutions formed by equivalent replacement, such as: three or more lower cables 2, four and two strands of upper cables 1, etc., all fall within the scope of protection required by the present invention.
