Description

Portable deposit ground support equipment Technical Field The present utility model relates to a portable deposit ground support apparatus, and more particularly, to a portable deposit ground support apparatus capable of opening a deposit valve of an auxiliary fuel tank in a cargo compartment of an aircraft and performing deposit maintenance work on the auxiliary fuel tank. Background The auxiliary fuel system is an important component of the aircraft, generally as an additional fuel system provided for increasing the flight path, and therefore an auxiliary fuel tank is provided in the auxiliary fuel system. As shown in fig. 8, the auxiliary fuel tank 2 is an additional fuel tank to the primary fuel tank of the original aircraft, and is generally disposed in the cargo hold so as to store additional fuel which is not directly supplied to the engine but is transferred to the primary fuel tank through the auxiliary fuel system, thereby enabling an increase in the range of the aircraft. The auxiliary fuel tank 2 is required to perform maintenance operations on the floor of the deposit, usually by opening a deposit valve 3 at the bottom of the auxiliary fuel tank 2 through a floor support device (GSE: ground Support Equipment), as shown in fig. 9, the deposit valve 3 being in communication with the cowling 4 of the aircraft through a liquid line PT, so that the deposits and aqueous solution at the bottom in the tank are discharged to the outside of the fuselage through the deposit line. However, since the auxiliary fuel tank 2 of the civil aircraft is usually located in the cargo compartment of the aircraft, and the purge line needs to be directly connected to the outside of the aircraft body, the operator cannot directly contact the purge valve 3 of the auxiliary fuel tank 2, and only the purge valve 3 needs to be opened by GSE dedicated equipment, and the open/close state of the purge valve 3 of the auxiliary fuel tank 2 cannot be visually confirmed because the purge valve 3 cannot be contacted, and the purge valve 3 needs to be kept in the open state all the time during operation. Furthermore, a deposit valve 3 is located at the bottom of the auxiliary fuel tank 2, and a deposit port FK is located at the surface of the main body, which is normally sealed by a plug, but in a maintenance state, the plug is removed and inserted into GSE equipment to perform a deposit operation. As shown in fig. 9, according to feedback from an operator in the field, when performing a deposit maintenance operation on the auxiliary fuel tank 2 by the conventional deposit Ground Support Equipment (GSE) 1', the operator needs to squat all the way under the abdomen of the aircraft and jack up the GSE equipment with his hand, the operation position is low, the posture of the operator is inconvenient, the shoulder burden is heavy, the ergonomics are not good, and the operator feels tired and uncomfortable during the operation, and therefore, the deposit operation needs to be further optimized. In the past, designers have also attempted to make a series of improvements to this operational problem. For example, in patent CN211001873U, a convenient type of sedimentation membrane-releasing conduit for an aircraft fuel tank is disclosed, which is composed of a sedimentation valve-releasing ejector pin, a conical oil collecting cavity, an annular viscous membrane, a membrane conduit, a discharge horn mouth, and a fixing adhesive tape. When the convenient film conduit is used for carrying out the sedimentation maintenance operation of the aircraft fuel tank, the annular adhesive film can be adhered to the surface of the aircraft skin through the protective film on the surface of the annular adhesive film, so that long-time handheld operation is avoided. However, the aircraft can vibrate in the flight process, in order to keep the valve tightly closed, the spring pressing force of the sedimentation valve of the auxiliary oil tank is large, and the possibility of falling off due to the fact that the adhesion of the annular adhesive film is not very strong and the adhesion cannot be effectively ensured, and an operator still needs to hold the aircraft in the maintenance process. In view of the foregoing deficiencies in the prior art, it would be desirable to provide a portable precipitation floor support device that is capable of suspending the floor support device without requiring a hand-held operation. Disclosure of utility model The present disclosure has been made to solve the above-mentioned problems, and an object thereof is to provide a portable deposit floor support apparatus by which a floor operator can complete deposit maintenance operation of an auxiliary fuel tank without long-term hand-held operation. In order to achieve the object of the present disclosure, there is provided a portable deposit floor support apparatus adapted to perform deposit maintenance operation on an auxiliary fuel tank of an aircraft, including a roof bar fo
