Abstract

In order to overcome the potential hazard and inconvenience in using due to unreasonable stress structures of crank shafts and nondisclosure of rope rewinding techniques in currently used airborne descent apparatus adopting crank shafts and speed-limiting pistons, the present invention provides an airborne descent apparatus, characterized in that: synchronizing rotating subassemblies are installed on both sides of the rope winding plate, and the crank shaft is installed between the rotating parts of the said synchronizing rotating subassemblies so as to resolve the problem of non-uniform stress. The unidirectional rotating elements are arranged for revolving the problem of rope rewinding. When the rope drives the rope winding plate to rotate toward one direction under the action of gravity and drives the crank shaft to rotate, the crank shaft drives a piston speed-limiting subassembly to operate. The piston speed-limiting subassembly is free of operating and the crank shaft is free of rotating when the rope winding plate rotates toward reverse direction.

Description

TECHNICAL FIELD

The present invention relates to a landing apparatus, and more particularly to a piston-type air speed landing apparatus.

TECHNICAL LEVEL

In everyday life or at work, people often face the risk of being at high altitude. There is no other way to get out of there, you will need an air landing apparatus. Various types of air landing apparatus are well known: based on friction speed limitation, manual breaker speed limitation, piston speed limitation. The first two have the disadvantage of low reliability, while the third has a relatively simple design and reliable operation. CN87216143 describes a descent apparatus which uses pistons and cams to limit its descent speed. However, the cam can only respond to pressure and not to stretching. Therefore, the speed limiting effect during landing is uneven. ZL20031 01127389 and ZL2003201232361 separately describe the principle of connecting the crankshaft to the piston speed controller, but due to the use of the chain ladder, the clearance height is limited. ZL2007202016917 describes a piston speed limiting air landing apparatus through which a rope passes through. First of all, the user must wear these life ropes correctly, which causes him / her inconvenience. Existing air deflectors using crankshafts and speed limiting pistons, which use only a passive component, have different forces on both ends of the crankshaft, which causes the problem of possible irrational tensioning, and does not provide any rope wrapping and there may be risks and inconvenience to the device.

THE SUBSTANCE OF THE INVENTION

To overcome the potential hazards and operational inconveniences of not presenting the crankshaft tensioning structure and rope wrapping techniques in current airborne landing gear using crankshafts and speed limit pistons, the present invention provides an airborne landing gear characterized in that the synchronizing rotary assemblies are mounted on both ropes on the sides of the plate, and the crankshaft is mounted between the rotating parts of said synchronizing rotary assemblies, thus solving the problem of uneven tension. Unidirectional pivoting elements are positioned to solve the rope winding problem. By rotating the rope winding plate in one direction under gravity and rotating the crankshaft, the crankshaft forces the piston speed limiter assembly into action. The piston speed limiter no longer works and the crankshaft no longer rotates when the rope winding plate rotates in the opposite direction.

The technical solution of the air deflector device provided with the present invention comprises the following main parts: main frame 1, rope winding plate assembly 2 and piston speed limiter assembly 3. The main parts of the main frame are support dock 1A and support dock 1B. The main parts of the rope winding unit assembly 2 are the winding plate 2.1 A, the winding plate 2.1 B, the central part 2.2, the rope 2.31, the end piece securing the rope 2.41 and the central axis 2.5. Rope 2.31 is wound on rope winding plates with a tie at the ends of the rope 2.41. The wrapping plate is mounted on support dock 1A and support dock 1B on the central axis passing through it 2.5. Main parts of piston speed limiter assembly 3 crankshaft 3.1, speed limiter piston 3.2, piston rod end connection 3.3, piston speed control part 3.6, piston propeller shaft 3.4A and piston propeller shaft 3.4B. Both the piston thrust shaft 3.4A and the piston thrust shaft 3.4B are secured in the thrust docks 1A and 1B. The crankshaft 3.1 is coupled to the rear piston rod joint 3.3 and is characterized in that the synchronizing rotary assemblies 4A and 4B are mounted on either side of the rope winding unit assembly 2 respectively. The rotary assembly 4A main parts are the rotary parts 4A11 and 4A12 as well as the rotary support shaft 4A4. . The rotating member 4A 11 is mounted on one side of the rope winding plate. Main parts of rotary assembly 4B rotary parts 4B11 and 4B12 as well as spindle support shaft 4B4. The rotating member 4B11 is mounted on the other side of the rope winding plate. The said crankshaft 3.1 is mounted between the rotating parts 4A12 and 4B12. The crankshaft supporting parts 4A6 and 4B6 are mounted on the rotating parts 4A12 and 4B12. The unidirectional rotary member 4A3 is mounted between the supporting crankshaft portion 4A6 and the rotary portion 4A12 and forms the first unidirectional composite member, and is mounted on the support dock 1A through the pivot support shaft 4A4. The unidirectional rotary member 4B3 is mounted between the anchors of the crankshaft 4B6 and the rotary part B12 to form the second unidirectional composite member, and is mounted on the support dock 1B through the rotary prop end shaft 4B4. The crankshaft 3.1 is mounted on the pivot shafts 4A6 and 4B6. Under gravity, rope 2.31 causes the plate assembly 2 to rotate, which causes the rotational assemblies 4A and 4B to rotate synchronously. The rotating pivot assemblies 4A and 4B force the fastening parts of the crankshafts 4A6 and 4B6 to rotate, which forces the crankshaft to rotate 3.1. The rotation of the crankshaft 3.1 acts on the piston speed limiter assembly 3, thereby providing resistance to the crankshaft 3.1 and limiting the rotation of the winding plate assembly 2. By adjusting the piston speed adjustment part 3.6, the rotation speed of the winding plate assembly can be varied. As the winding plate assembly 2 rotates in the opposite direction, the rotation assemblies 4A and 4B are forced to rotate. Because the unidirectional rotary members 4A3 and 4B3 are located between the rotating parts 4A12 and 4B12 and the crankshaft supporting parts 4A6 and 4B6, the supporting crankshaft parts 4A6 and 4B6 do not rotate, nor does the crank. The piston speed limiter assembly 3 does not work. So, the rope wrapping problem is solved.
