The resistance is applied to the crank shaft (3.1) by the piston speed-limiting subassembly (3) so as to confine the rotation of the rope winding plate (2). The rotating speed of the rope winding plate (2) can be adjusted through regulating a piston speed regulation part (3.6).

Description

TECHNICAL FIELD

The present invention relates to an airborne landing device, more particularly to a piston speed limiting transportable landing device.

TECHNICAL LEVEL

In everyday life and at work, people often encounter dangerous situations at high altitudes, and if there is no other way to survive, they need to use a transportable landing device. Well-known types of airborne landing devices include anti-friction devices, speed limiting devices with handbrake, and speed limiting devices with hydraulic damping. The disadvantage of the first two types is their low reliability, while the latter type has reliable performance and relatively simple construction. Known patent CN87216143, which describes a descent device limiting descent velocity by pistons and cam. However, the cam can only withstand pressure, not stretching, which limits the speed during landing. Known patents ZL2003101127389 and ZL2003201232361 disclose the principle that the crankshaft is connected to a hydraulic speed controller, but the drop height is limited by the use of a chain staircase. Known patent ZL2007202016917 describes a piston speed limiting airborne landing device constructed using a rope moving through the device. In order to use this device, a person first has to be properly fastened with such life ropes, which can be quite difficult for some people. In existing airborne landing systems using crankshafts and speed-limiting pistons, the forces at both ends of the crankshaft are different, since the piston is only a passive component. As a result, the structure may be subjected to unnecessary stress and may present a danger to persons using the structure.

THE SUBSTANCE OF THE INVENTION

In order to overcome the drawbacks of current airborne landing devices with crankshafts and speed limiting pistons, the present invention proposes a new transportable landing device, based on the following principle: synchronously rotating drive components are provided and a crankshaft is provided between their rotating parts. As the wrapping plate rotates, the rotating parts and the crankshaft rotate together. The crankshaft rotation is triggered by the piston speed limiter block which causes resistance to the crankshaft, thereby limiting the rotation of the winding plate block. The rotation speed of the wrapping plate can be controlled by the piston speed regulator.

The technical solution of the airborne landing device of the present invention is the following: the main body 1, the cable winding plate block 2 and the piston speed limiting plate 3. The main parts of the cable winding plate block are the left winding plate 2.1 A, the right winding plate

2.1 B, center part 2.2, cable 2.31 and cable end lock 2.41 and center axle 2.5. Rope 2.31 is wound between the rope winding plates and a rope 2.41 is attached to the ends of the rope. The wrapping plate is arranged between the left support 1A and the right support 1B on the central axis 2.5. The main parts of the piston speed limiter are crankshaft 3.1, speed limiter piston 3.2, piston rod end connection 3.3, piston left bearing shaft 3.4A, piston right bearing shaft 3.4B, piston left lock 3.5A, piston right lock 3.5B, regulator 3.6; both the piston left propeller shaft 3.4A and the right piston propeller shaft 3.4B are fastened to the speed limiter piston 3.2 and connected to the piston left lock 3.5A and right piston lock 3.5B, respectively, and the piston left and right lock 3.5A and 3.5B in turn, are secured to the left and right supports 1A and 1B, respectively. The crankshaft 3.1 joins the piston rod end connection 3.3 and is characterized in that the left and right synchronous rotating washers 4A and 4B are respectively mounted in each of the cable winding plates. 2 on the sides. The main parts of the left synchronizing rotating pad 4A are the first left rotating part 4A11, the second left rotating part 4A12 and the left locking part 4A3. The first left rotating member 4A11 is mounted on one side of the cable winding plate, and the second left rotating member 4A12 is secured to the left latch 4A3 which in turn is secured to the left support 1A. In a similar way, the main parts of the right synchronizing rotating sleeve 4B are the first right rotating part

4B11, Second right rotary part 4B12, and Right lock 4B3. The first right rotary portion 4B11 is secured to the other side of the cable winding plate and the second right rotary portion 4B12 is secured to the right retainer 4B3 which in turn is secured to the right abutment 1B. The crankshaft 3.1 is provided between the second left-hand rotating part 4A 12 and the second right-hand rotating part 4B12. Under gravity, the cable

2.31 rotates the plate bearing 2, from which the left and right synchronizing rotating arms 4A and 4B are rotated, while the crankshaft 3.1. When the crankshaft 3.1 is rotated, the piston speed limiter 3 is actuated therefrom, causing resistance to the crankshaft 3.1 and limiting the movement of the winding plate follower 2. By adjusting the piston speed regulator 3.6 it is possible to change the speed of rotation of the wrapping plate flap 2.

The present invention also provides an additional solution: the main body 1 is provided with a main cable component 5 which may consist of at least two roller parts mounted in the main body 1 through the connecting plates at the top and bottom. The top and bottom rollers shall be installed with respect to the winding and tensioning directions of the wire rope. The upper and lower roller parts are arranged crosswise. As the wire rope 2.31 moves, it always presses and moves crosswise along the surfaces of the upper and lower rollers. Optimized Example: The main parts constituting component 5 of the main cable are the first roll part 5.1 A 1 and the second roll part 5.1 B1, the first axle 5.1A12 and the second axle 5.1 B12, and the first connecting plate 5.2A and the second connecting plate 5.2B.

The main parts of the second roller part 5.1B1 are the second roller element 5.1B11 with bearings and the second axle 5.1B12. The first roller element

5.1 A1 and the first axle 5.1A12 are mounted at the top, while the second roller element 5.1 B1 and the second axis 5.1 B12 are mounted at the bottom to form a #, and the hollow center of this # shape moves the cable 2.31. When the cable 2.31 intersects the surfaces of the first roller member 5.1A11 and the second roller member 5.1B11, the first roller part 5.1A1 and the second roller part 5.1B1 begin to rotate there. Rolling friction between rope 2.31 and the roller elements will reduce rope wear, but at the same time limit the rope

2.31 movement # in the hollow center to keep the landing gear stable.

The main body 1 is in the shape of a shell and is made up of overlapping left-hand support 1A and right-hand support 1B. Preferably, the left support 1A and the right support 1B are made by die-casting. The piston left latch 3.5A, left latch 4A3, and piston right latch 3.5B, right latch 4B3 are respectively mated to left support 1A and right support 1B by die-casting.

An optimized embodiment of the present invention: it also utilizes a fastening strap 6 attached to the main body 1.

Connectors 6.14 and 6.24 are connected to each other to form a strap and are used to tie the landing gear to the human waist. The cable end lock 2.41 must be mounted high and, under gravity, the lowered object (human body) will slowly lower. In this embodiment, the construction of the strap 6 is illustrated only in the diagram. The design and method of attachment of the strap 6 can be adjusted using known strap designs. There are known quick connectors that can be fitted to each harness connector 6 for convenience. Quick connectors are often used in backpacks and are therefore not marked on the drawings. In this embodiment, an elastic cushion can also be attached to the support 1A for greater safety and comfort by attaching a descent device to the back. The cushioning of the elastic cushion is also a known technology and is not shown in the drawings.
