Description

Technical Field

[0001] The utility model relates to a telescopic bracket, in particular to a telescopic bracket for an aviation refueling hose. Background Art

[0002] At present, many aircraft positions at many airports are refueled by tanker trucks, that is, the tanker truck drives to the vicinity of the outer side of the aircraft wing, and then the refueler pulls out the refueling hose in the large reel on the refueler truck by manpower, drags the hose to the bottom of the aircraft wing at least 10 meters away, and then connects it to the refueling port on the underside of the wing through the refueling connector on the refueling hose to refuel the aircraft. In the process of dragging the refueling hose, the hose is always attached to the ground, the resistance is huge, it is very laborious, and it will cause serious wear and tear to the hose over time. Although it is not very laborious to pull it back by the mechanical refueler truck in the process of retrieving the hose, the wear and tear caused to the hose is also inevitable. Therefore, it is necessary to design an aviation refueling hose telescopic bracket to facilitate the refueler to pull out and retract the refueling hose over a long distance. Summary of the invention

[0003] The utility model adopts an aviation refueling hose telescopic bracket, comprising a telescopic bracket (3), a loudspeaker drum (1), a supporting foot (5) and a roller (6). The telescopic bracket is used to drive the loudspeaker drum to move and support the refueling hose to move in the horizontal direction. The loudspeaker drum can reduce the friction resistance with the hose by rolling by itself, and the characteristics of being low in the middle and high on both sides prevent the hose from deviating to the left and right. The supporting foot is at the end of the telescopic bracket and a roller that can be locked by stepping on the bottom is provided.

[0004] Preferably, the telescopic bracket is shaped like a household telescopic ladder, consisting of many circular telescopic rods with successively smaller diameters and an intermediate connecting rod connected in a straight line, but the difference is that the retraction of each section of the household telescopic ladder requires manual unlocking of the locking pin, while each section of the telescopic rod of the aviation refueling hose telescopic bracket can be freely extended and retracted.

[0005] Preferably, the telescopic bracket is provided with a plurality of horn rollers, which can be brought to a distant place by the extension of the telescopic bracket, so that the oil filling hose can slide straightly above the horn rollers, thereby reducing friction resistance and not deviating left and right.

[0006] Preferably, the support leg can swing 90° around the support leg rotation joint (7), and after being stretched out to form a right angle with the telescopic bracket, it is fixed with a pin, so as to support the telescopic bracket to move in a horizontal direction. After the telescopic bracket is retracted and erected, it can be retracted and placed in a direction parallel to the telescopic bracket.

[0007] Preferably, the front end of the telescopic bracket is provided with a swivel joint (4), which is installed under the refueling hose reel on the refueling truck to allow the telescopic bracket to be lowered horizontally or folded upright.

[0008] Preferably, the bottom of the support feet is equipped with rollers with a locking function, which can support the horizontal movement of the support feet. When the telescopic bracket is extended to a certain length, step on the locking rollers to restrict the movement of the telescopic bracket.

[0009] Furthermore, the telescopic bracket provided by the present utility model is very labor-saving when pulled and pushed back by a person. When the refueling hose of the refueling vehicle is mechanically retracted, the bracket can also be pulled back by means of the refueling connector at the end of the refueling hose.

[0010] Furthermore, after the telescopic bracket with a length of about 8 meters is retracted, it is only about 2 meters, occupying a small space. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0016] Step 1, when it is necessary to pull out the refueling hose, rotate the telescopic bracket around the rotating joint and lower it to the horizontal position, open the support feet to form a right angle with the telescopic bracket, and fix the angle with a pin.

[0017] Step 2, pull out a section of the refueling hose and place it on the horn roller. At the same time, pull the refueling hose and the telescopic bracket away from the refueling vehicle. After pulling to a certain distance, step on the locking mechanism of the roller to fix the position of the telescopic bracket. If additional length is required, the refueling hose can be pulled further.

[0018] Step 3, when it is necessary to retract the refueling hose, one person operates the mechanical retraction of the refueling vehicle. After the refueling hose drives the refueling connector at the end back to the end of the telescopic bracket, while retracting the refueling hose, another person holds the hose and pushes back the telescopic bracket at the same time.

[0019] Step 4, when the refueling hose is retracted in place, rotate the telescopic bracket around the rotating joint to stand it up, pull out the pin of the support foot, lower the support foot, and tie it down for fixation.

[0020] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of protection of the present utility model.
