Description

Technical Field

[0001] The utility model relates to the technical field of aircraft refueling vehicles, in particular to an auxiliary support arm of a refueling platform of an aircraft refueling vehicle. Background Art

[0002] At airports, aircraft refueling is usually completed by special aircraft refueling vehicles. In the current aviation fuel refueling process, the removal and installation of aircraft refueling connectors is an important and complicated step.

[0003] However, traditional manual operation is inefficient. The platform refueling connector and hose weigh approximately 17 kg, and the refueler must lift the refueling connector and hose 2 meters to connect the aircraft refueling connector to the aircraft refueling port during refueling. In addition, with the continuous upgrading of aircraft models and the increasing functionality, the weight of the refueling connector is also increasing, placing higher demands on the operator's labor intensity.

[0004] Therefore, we propose an auxiliary support arm for the refueling platform of an aircraft refueling vehicle. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as the heavy weight of the refueling joint, high labor intensity and low efficiency of manual operation, and to propose an auxiliary support arm for the refueling platform of an aircraft refueling vehicle.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An auxiliary support arm for a refueling platform of an aircraft refueling vehicle, comprising:

[0008] The base comprises a first support arm rotatably connected to the top of the base, a second support arm rotatably connected to the top of the first support arm, a movable seat rotatably connected to the top of the second support arm, an upper shell, a lower shell, an upper gas support and a lower gas support rotatably connected to one side of the movable seat, the upper shell and the lower shell are slidably connected, and the other ends of the upper shell and the lower shell are rotatably connected to the same connecting seat, a universal joint is fixedly provided at the other end of the universal joint, and a tapered groove kit is fixedly provided at the other end of the upper gas support, the other end of the upper gas support is rotatably connected to the surface of the upper shell, and the other end of the lower gas support is rotatably connected to a mounting block, and the mounting block is fixedly provided on the top inner wall of the upper shell;

[0009] The oil pipe is also included. The top end of the oil pipe is rotatably connected to a refueling joint. The outer wall of the oil pipe is fixed with a tapered hook. The tapered hook and the tapered groove kit are used in conjunction with each other.

[0010] The limiting mechanism is arranged on one side of the upper shell and is used to limit the upper shell and the lower shell.

[0011] In one possible design, the limiting mechanism includes a height pin, which is threaded through the surface of the upper shell, and a clearance hole is opened on the surface of the mounting block. The bottom end of the height pin passes through the clearance hole and conflicts with the bottom inner wall of the lower shell.

[0012] In one possible design, the limiting mechanism also includes a self-locking pin and a locking tube, wherein the self-locking pin thread passes through the outer wall of one side of the upper shell, and the locking tube is fixed between the inner walls of both sides of the lower shell, and one end of the self-locking pin passes through the upper shell and is located on the inner side of the locking tube.

[0013] In a possible design, a clearance opening is opened on one side of the bottom of the upper shell and the lower shell, and the lower gas strut passes through the clearance opening.

[0014] In one possible design, the tapered groove kit includes a mounting tube, the inner wall of the mounting tube is slidably connected to a tapered bucket, a tension spring is fixed between the tapered bucket and the mounting tube, the tension spring is sleeved on the outer wall of the tapered bucket, the outer wall of the mounting tube is provided with a sliding groove, an L-shaped stopper is slidably connected in the sliding groove, a spring is fixed between the stopper and the mounting tube, a through hole is provided on the surface of the stopper, and the through hole and the bottom end of the tapered bucket are staggered.

[0015] In a possible design, a limiting block is fixedly provided at one end of the stop block, and the limiting block contacts the outer wall of the mounting tube.

[0016] In this application, when used:

[0017] 1. Initial state: The platform auxiliary support arm is at a horizontal angle, the upper and lower shells are horizontal as a whole, and the refueling joint is hung on the platform fence using a tapered hook;

[0018] 2. The operator climbs onto the platform and the operating platform rises to an appropriate height;

[0019] 3. Remove the oil pipe and taper hook from the platform fence, and connect the taper hook and taper bucket;

[0020] 4. Use the first and second arms to adjust the refueling connector to the appropriate position. Then rotate the self-locking pin to disengage the locking tube, releasing the limit on the lower housing. Then rotate the height pin to disengage the lower housing, releasing the limit on the lower housing again. Since the upper gas strut applies tension to the upper housing, and the lower gas strut applies thrust to the upper housing, it helps the staff to easily complete the lifting of the refueling connector, causing the upper and lower housings to rotate, thereby driving the connecting seat, taper groove kit, and refueling connector to rise near the aircraft fuel tank. Then rotate the height pin so that the bottom end of the height pin contacts the bottom inner wall of the lower housing. Then align the refueling connector with the refueling port, rotate the refueling connector, and tighten it.

[0021] 5. Push the block, which drives the through hole to move, so that the through hole and the tapered bucket are aligned. Under the action of the tension spring, the tapered bucket extends into the mounting tube and disengages from the tapered hook, preventing the tapered bucket from interfering with the tapered hook.

[0022] 6. Press the upper shell to rotate and return the upper and lower shells to their initial state. Then rotate the self-locking pin into the locking tube to complete the position limit of the upper and lower shells and wait for the next use.

[0023] 7. Lower the operating platform to zero position and then leave the platform and start refueling;

[0024] 8. After refueling is completed, the operator climbs onto the platform, raises the operating platform to an appropriate height, screws the refueling connector to disengage it from the refueling port, and then hangs the refueling connector back to its fixed position;

[0025] 9. The operating platform descends to zero position, completing the entire refueling process.

[0026] Beneficial effects: In the utility model, the auxiliary support arm of the refueling platform of the aircraft refueling vehicle can provide additional assistance by using the upper gas support, the lower gas support and the upper shell, so that the staff can easily adjust and connect the refueling joint position, reduce the labor intensity of the staff and improve work efficiency;

[0027] In the utility model, the auxiliary support arm of the refueling platform of the aircraft refueling truck is provided with a tapered groove kit, so that the tapered bucket can be disengaged along the direction of the tapered hook, thereby avoiding interference between the tapered hook and the refueling connector and avoiding displacement of the refueling connector under force;

[0028] In the utility model, the upper and lower gas supports can be used to provide additional assistance, so that the staff can easily complete the adjustment and docking of the refueling joint position, reducing the labor intensity of the staff and improving work efficiency, so that the tapered bucket can be disengaged along the direction of the tapered hook, avoiding interference with the tapered hook and the refueling joint, and avoiding the refueling joint from being offset by force.
