Description

TECHNICAL FIELD

[0001] The present application relates to a vehicle-mounted maintenance cabin and a maintenance vehicle, in particular to an aircraft conduit field maintenance cabin and a maintenance vehicle. BACKGROUND

[0002] Aircraft conduit maintenance has always been one of the most difficult work in aircraft maintenance. The conduit is distributed in the engine, fuel supply system, hydraulic system, lubrication system, cooling system, etc. of the aircraft, and the conduit in these systems may fail and need to be repaired. Due to the factors such as repeated disassembly and assembly difficulty, complex shape, multiple types, multiple processing procedures, and storage difficulty, the equipment tooling used for conduit maintenance is more, and the professional requirements for the operators are higher, so the maintenance work related to the conduit is generally carried out in the aircraft maintenance base.

[0003] For combat aircraft, field maintenance of the aircraft is a necessary condition to ensure the flight time of the aircraft, the number of available aircraft, and the safety of the aircraft and pilots. Therefore, improving the field maintenance capability of the combat aircraft has important significance for enhancing the air force power. The existing aircraft field conduit maintenance schemes include a container type maintenance cabin, a trailer type maintenance cabin, and a large heavy truck maintenance cabin.

[0004] The container type maintenance cabin: 1. It is only suitable for short distance dragging maintenance operation and cannot be applied to complex road conditions such as battlefield and urban road. 2. When moving for a short distance, an independent external wheel needs to be used for pushing. 3. When being transported for a long distance, it needs to be installed on a large truck, and the vehicle needs to bear a high load and a large loading space, and the requirement for the ground road condition is higher. 4. When being transported for a long distance, the independent external wheel needs to be put into the cabin, which occupies the space in the cabin.

[0005] The trailer type maintenance cabin: it can only be applied to a site with good road condition and open maintenance site, and cannot be applied to complex road conditions such as battlefield and urban road.

[0006] The large heavy truck maintenance cabin: 1. It cannot be applied to complex road conditions such as battlefield and urban road. 2. When being transported for a long distance, it needs to be installed on a large truck, and the vehicle needs to bear a high load and a large loading space, and the requirement for the ground road condition is higher.

[0007] The above three schemes have some common shortcomings: 1. The operation space is completed in the vehicle compartment, which is not suitable for complex duct processing in terms of space layout. 2. When the duct is repaired, the worker completely enters the repair cabin and operates indoors, which occupies a large space and is not conducive to the flexible configuration of the repair cabin and the vehicle. 3. The indoor space is relatively small and closed, which reduces the processing efficiency of the worker and affects the communication between the worker and the working site outside the vehicle compartment. 4. It is not conducive to equipment maintenance or other possible equipment docking. 5. Duct processing is prone to generate metal dust and debris, which will affect the quality of duct processing and is not conducive to keeping clean. 6. The crowded indoor space is not conducive to simultaneous operation of multiple stations.

One end of the torsion spring 3254 abuts against the lock seat 321, and the other end abuts against the lock catch 325. A clamping slot 3221 is arranged on the lock tongue 322. When the lock tongue 322 is moved out of the gap 320, the clamping portion 3252 enters the clamping slot 3221 under the action of the torsion spring 3254, thereby clamping the lock tongue 322. As shown in Figure 19 As shown in Figure 20 , 21 When the lock tongue 322 is retracted into the sliding slot 3210 by pulling the connecting rod 323, the clamping slot 3221 on the lock tongue 322 moves to a position opposite the clearance slot 3212, so that the clamping portion 3252 enters the clamping slot 3221. As shown in Figure 22 , 23 At this time, the connecting rod 323 is released, and the lock tongue 322 moves outward under the action of the first compression spring 324, so that the clamping portion 3252 is clamped tightly against the bottom of the clamping slot 3221. At this time, the tube locker 32 is in an open state, and the catheter can be stored or taken out. When it is necessary to close the tube locker 32, the knob portion 3253 is pressed, so that the lock catch 325 is separated from the clamping slot 3221. Then, the lock tongue 322 extends out of the sliding slot 3210 under the action of the first compression spring 324.
