[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0039] like Figure 1-3 As shown, an air conditioning connector withdrawal system includes: an umbilical tower 100, an air conditioning hose 200, an air conditioning connector 300, a telescopic limiting mechanism 400 and a pulling wire rope 500.

[0040] The air conditioning hose 200 includes a main body portion and a free end portion which are interconnected, wherein the main body portion is fixedly connected to the umbilical tower 100. The air conditioning connector 300 is fixedly arranged at the end of the free end portion. The air conditioning hose 200 is fixedly connected to the fairing 10 through the air conditioning connector 300 in a pluggable manner.

[0041] The telescopic limiting mechanism 400 is fixedly mounted on the umbilical tower 100 ; the telescopic limiting mechanism 400 includes a telescopic limiting body 410 and a limiting ring 420 as the swing center of the air conditioning connector 300 after plugging and unplugging. The limiting ring 420 is fixedly connected to the limiting body 410 .

[0042] The pulling wire rope 500 is inserted into the limiting ring 420. One end of the pulling wire rope 500 is fixedly connected to the air conditioner connector 300, and the other end is fixedly arranged on the pulling winch.

[0043] The telescopic limit mechanism 400 is configured to control the swing center of the air conditioner connector 300 to move to a preset position through its telescopic movement. The pulling winch is configured to shorten the swing distance between the air conditioner connector 300 and its swing center after the plugging and unplugging through the winding action.

[0044] It should be noted that the preset position of the swing center of the air-conditioning connector 300 after unplugging means that when the air-conditioning connector 300 is under the action of gravity and the tension of the pulling wire rope 500, the air-conditioning connector 300 makes a pendulum motion with the swing center, and when in the preset position, the air-conditioning connector 300 will not touch the fairing 10, nor will it touch the umbilical tower 100.

[0045] Preferably, the limiting ring 420 is fixedly disposed below the limiting body 410, so that the limiting ring 420 can limit the pulling wire rope 500, thereby enabling the limiting ring 420 to serve as the swing center of the air-conditioning connector 300 after plugging and unplugging.

[0046] In the embodiment of the present invention, the position limiting body 410 includes a fixing seat 411, a first body 412, a second body 413 and a telescopic driving device 414. The first body 412 is fixedly connected to the fixing seat 411, the first body 412 is slidably connected to the second body 413 along a straight line, and the telescopic driving device 414 is configured to drive the second body 413 to slide along a straight line relative to the first body 412.

[0047] The first main body portion 412 and the second main body portion 413 are both disposed at an acute angle to the horizontal line or the first main body portion 412 and the second main body portion 413 are both disposed horizontally.

[0048] The first main body portion 412 and the second main body portion 413 are arranged in a colinear manner at their connection; the first main body portion 412 is sleeved on the outside of the second main body portion 413 at the connection with the second main body portion 413 .

[0049] It should be noted that the fixing seat 411 is a "7"-shaped structure, which is convenient for fixing it to the umbilical tower 100, and can also facilitate the first main body 412 and the second main body 413 to be arranged horizontally or at an acute angle to the horizontal line.

[0050] In addition, the fixing seat 411 can also be a "1-shaped structure, and the first main body 412 is connected to the fixing seat 411 vertically, so as to ensure the fixation of the limiting main body 410 and the umbilical tower 100, and at the same time, it is conducive to the horizontal arrangement of the first main body 412 and the second main body 413 or the arrangement at an acute angle to the horizontal line.

[0051] Preferably, the telescopic drive device 414 is one of a cylinder, a hydraulic cylinder or an electric push rod. In the length direction of the first main body 412 and the second main body 413, one end of the telescopic drive device 414 is fixedly connected to the first main body 412, and the other end is fixedly connected to the second main body 413. Under the drive of the telescopic drive device 414, the relative movement of the first main body 412 and the second main body 413 can be achieved, thereby achieving the telescopic movement of the limit main body 410 in the horizontal direction.

[0052] As another embodiment of the present invention, the umbilical tower 100 also includes a lifting mechanism 600 for adjusting the height of the telescopic limit mechanism 400. The fixed seat 411 is fixedly connected to the moving part of the lifting mechanism 600 in the vertical direction. Relying on the lifting and lowering action of the lifting mechanism 600, the telescopic limit mechanism 400 can be adjusted in height in the vertical direction, which is particularly convenient for controlling the height of the limit ring 420, so that the air-conditioning connector 300 can be in a better swing center for pendulum motion after being unplugged. At the same time, relying on the adjustment action of the lifting mechanism 600, the air-conditioning connector withdrawal system can withdraw the air-conditioning connector 300 installed on the fairing 10 at different heights, and has a wider range of adaptability.

[0053] Preferably, the lifting mechanism 600 is a screw lift.

[0054] As another embodiment of the present invention, the fixed seat 411 and the moving part of the lifting mechanism 600 are rotationally connected in the horizontal direction through a bearing 700. Relying on the rotation action, the limiting main body 410 can rotate in the horizontal direction, which is convenient for adjusting the horizontal angle relative to the air-conditioning connector 300, and thus can be in a more retracted position.

[0055] As another embodiment of the present invention, the umbilical tower 100 is a telescopic structure including multiple tower sections, and adjacent tower sections are slidably connected, so that the umbilical tower 100 can be telescoped vertically. When the air conditioning connector 300 is plugged into the fairing 10, the umbilical tower 100 is in an extended state, and can support the air conditioning hose 200, thereby ensuring that the air conditioning hose 200 provides constant temperature clean air to the fairing 10.

[0056] After the air-conditioning connector 300 is detached from the fairing 10 , the umbilical tower 100 is shortened, so that the air-conditioning connector 300 can be brought to a lower height, thereby facilitating the air-conditioning connector 300 to fall to the ground.

[0057] A method for withdrawing an air conditioner connector, using the above-mentioned air conditioner connector withdrawal system for withdrawal, comprising:

[0058] The pulling winch pulls the pulling wire rope 500 to move, so that the air conditioner connector is unplugged, and the air conditioner connector 300 falls down under the action of gravity and the limiting action of the pulling wire rope 500;

[0059] The telescopic limiting mechanism 400 performs telescopic movement in a direction perpendicular to the rocket axis, so that the swing center of the air conditioning connector 300 moves to a preset position;

[0060] The pulling winch is continuously wound up, and under the winding action, the distance between the air-conditioning connector 300 after being unplugged and the swing center is shortened;

[0061] The pulling winch continues to reel in until the air conditioning connector 300 is hung at a preset position.

[0062] As another embodiment of the present invention, after the pulling winch continues to wind up until the air conditioner connector 300 is hung at a preset position, it further includes:

[0063] A guide rope is provided on the air conditioning connector 300 and can be pulled underneath the air conditioning connector 300;

[0064] The air conditioning connector 300 is lowered by pulling the winch, and during the lowering process of the air conditioning connector 300, the guide rope is pulled to guide the air conditioning connector 300 to prevent the air conditioning connector 300 from touching the rocket body or the umbilical tower 100; until the air conditioning connector 300 is lowered to the ground.
