Abstract
The invention discloses a general aircraft engine dismounting trolley, which is characterized in that a mounting trolley is additionally arranged on the original aircraft engine dismounting trolley, the mounting trolley consists of a support lug, a floating support mechanism, a support plate, an arc plate, a support plate, a transition base and a pull rod, and has dismounting functions of two engines of threo-27, threo-30, fighter-11B and fighter-10 types. The invention improves the integration degree of airplane engine maintenance, slows down the pressure of maintenance, maintenance and transportation of the airplane with multiple types of aircrafts in the army, improves the maneuvering guarantee capability, meets the requirement of the army on multi-airplane maintenance, and has great popularization value.
Description
Technical Field
The invention belongs to the technical field of military aircraft support, and relates to a large-scale disassembly and assembly machine for an aircraft engine, which is suitable for disassembling and assembling two engines (an al-31 phi N engine and a turbofan 10 engine) of four types of engines, namely a Su-27 aircraft, a Su-30 aircraft, a Jian-11B aircraft and a Jian-10 aircraft.
Background
Present army's current engine dismouting unwheeling is according to the difference of different aircraft model engine mounting means, has been equipped with two kinds of special engines respectively and has dismantled and assemble unwheeling: one type is used for meeting the dismounting requirements of engines of Su-27 airplanes, Su-30 airplanes and Jian-11B airplanes, the other type is used for meeting the dismounting requirements of engines of Jian-10 airplanes, the universality is poor, and great pressure is brought to maintenance, maintenance and transportation guarantee of aircrafts of troops, so that a general aircraft engine dismounting trolley needs to be designed to meet the requirements of the aircrafts of the troops.
Disclosure of Invention
The invention relates to a general aircraft engine dismounting trolley, which is characterized in that a mounting trolley is additionally arranged on the original aircraft engine dismounting trolley, the mounting trolley consists of a support lug, a floating support mechanism, a support plate, an arc plate, a support plate, a transition base and a pull rod, and has dismounting functions of two engines of Su-27 type, Su-30 type, Jian-11B type and Jian-10 type.
The engine mounting and dismounting frame trolley and the mounting frame small workshop are connected together through a roller and a positioning guide rail mechanism, the support plate is welded with the transition base, and the rest parts are connected through bolts; the support lugs are separately arranged at two ends of the supporting plate and used for supporting the front support of the engine, a floating support mechanism is adopted, and the support lugs at the two ends are attached to the maximum stress surface of the front support of the engine; the supporting plate is connected with the arc-shaped plate through a high-strength bolt, and the arc-shaped plate is of an arc-shaped structure and can enter the airplane body along an annular gap between the airplane body and the engine.
The pull rod assembly is composed of two groups of movable connecting rods, the distance between the two groups of movable connecting rods is 50mm, left and right threaded connecting seats are arranged at two ends of each group of movable connecting rods, the position of the connecting point of the rear frame of the engine can be adjusted, and the adjusting distance can reach 80 mm. The front connecting rod of the support lug and the pull rod assembly is used for realizing the connection of an original-31 phi N type engine, and the rear connecting rod of the support lug and the pull rod assembly is used for connecting a turbofan-10 type engine.
The invention realizes the purpose of meeting the requirements of a Su-27 airplane, a Su-30 airplane and a Jian-11B airplane engine (an L-31 phi N and a turbofan 10 engine). The engine disassembly and assembly trolley of 3 types of engines and 2 types of engines (an-31 phi N and a turbofan 10 engine) and the engine disassembly and assembly functions of 2 types of trolleys which meet the disassembly and assembly of the special engine of the Jian-10 airplane are integrated on one engine disassembly and assembly trolley, so that the integration degree is greatly improved, the manufacturing and maintenance cost is saved, and the maneuvering guarantee capability of the new army of our army for united maneuvering transition training and fighting is enhanced.

Detailed Description
The invention relates to a universal aircraft engine dismounting trolley which comprises two parts, namely an original engine dismounting trolley and a mounting trolley additionally designed. The mounting frame trolley (shown in figure 2) is composed of two support lugs 1, two floating support mechanisms 2, a supporting plate 3, an arc-shaped plate 4, a supporting plate 5, a transition base 6 and two pull rods 7, and parts are shown in figures 3-8. .
The support plate 5 and the transition base 6 of the mounting frame trolley are connected in a welding mode, and the rest are connected through bolts. The original engine dismounting frame trolley is connected with the mounting frame trolley through the roller and the positioning guide rail mechanism.
When the airplane body support lug is used, the support lugs are respectively arranged at two ends of the support plate and used for supporting the front support of the engine, the support plate is connected with the arc-shaped plate through 8 countersunk head high-strength bolts, the arc-shaped structure is adopted, the arc-shaped structure can enter the airplane body of the airplane of. The pull rod assembly is composed of 2 groups of movable connecting rods, the distance between the two groups of movable connecting rods is 50mm, left and right thread connecting seats are arranged at two ends of each group of movable connecting rods and can be adjusted according to the position of a connecting point of a rear frame of the engine, the adjusting distance can reach 80mm, the support lug and the front connecting rod of the pull rod assembly are used for realizing the connection of an A-31 phi N type engine, and the support lug and the rear connecting rod of the pull rod assembly are used for connecting a turbofan-10 type engine.
