Fixing device of airplane gravity oil gun

Abstract

The invention discloses a fixing device of an airplane gravity oil gun. The device comprises a gravity oil gun placing seat and a round mouth spray pipe placing seat, the gravity oil gun placing seatcomprises an oil gun seat bottom plate and an oil gun pipe fixing plate, two sides of the oil gun seat bottom plate are bent upwards in a U shape and are fixedly connected with the oil gun pipe fixingplate, a fixed cabin is formed between the oil gun seat bottom plate and the oil gun pipe fixing plate, springs are fixed to the two sides of the inner side of the oil gun seat bottom plate, each spring is connected with an oil gun baffle, and a first round hole is formed in the front portion of the oil gun seat bottom plate and used for installing a sensor matched with an aircraft refueling vehicle, the round mouth spray pipe placing seat comprises a round mouth spray pipe barrel seat and an end cover matched with the round mouth spray pipe barrel seat, and a fixing support is fixed to bottom of the round mouth spray pipe barrel seat. The device is small in weight and easy, convenient and rapid to operate and is provided with the round mouth spray pipe placement seat; the device is installed in a matched mode according to a sensor used on an aircraft refueling vehicle, so that the implementation of the electrical interlocking function of the aircraft refueling vehicle is achieved.

Description

technical field [0001] The invention relates to the field of aircraft refueling equipment on the airport ground, in particular to a fixing device for an aircraft gravity refueling gun. Background technique [0002] Aircraft refueling vehicles are generally equipped with a gravity refueling reel nozzle and a gravity refueling gun for gravity refueling of the aircraft. The gravity refueling gun must be fixed with an interlocking brake sensor while requiring easy access. When the refueling gun is taken out, the vehicle will Brake, and the refueling gun returns to release the brake. In addition, aircraft fuel generally has two types of aviation kerosene and aviation gasoline. Due to the different characteristics of the two types of fuel, the nozzles used for filling are different, and mixed use is not allowed to avoid danger. At present, in the aircraft refueling safety standards and related regulations at home and abroad, the nozzles used for the two types of fuel are distingu...

AI Technical Summary

Problems solved by technology

At present, in the aircraft refueling safety standards and related regulations at home and abroad, the nozzles used for the two types of fuel are distinguished by flat heads and round heads, but users of refueling vehicles still have mixed use of nozzles when repairing and replacing parts, which violates safety regulations. question

[0003] At present, the gravity refueling gun of refueling trucks is generally placed in a box. When the road surface is bumpy during driving, the refueling gun often leaves the position and causes braking, which has a great impact on driving safety; it does not refuel both aviation kerosene and aviation gasoline. Differentiated use and fixed design of guns will cause danger; at the same time, the current fixing devices are high in cost and heavy in weight, making it difficult to install and inconvenient to operate
