Description

Technical Field

[0001] This utility model relates to the field of aviation maintenance technology, specifically to a device for the maintenance and handling of auxiliary power units. Background Technology

[0002] Small aircraft engines require more frequent maintenance and inspection. Compared to large aircraft engines, small engines are smaller in size and have fewer coils, making them more prone to failure. Therefore, they need to be inspected and maintained more frequently. Maintenance and inspection require the use of handling equipment. Traditional handling equipment has limited storage space and a fixed movement trajectory, which cannot flexibly change the direction and route of movement.

[0003] Existing handling equipment for small aircraft engines has fixed storage space and a fixed movement trajectory. For example, a handling AGV disclosed in CN218877440U includes a chassis and a handling module. The handling module is mounted on the chassis and includes limiting members and a telescopic assembly. Pairs of limiting members are arranged opposite each other in a first direction, and the telescopic assembly is located between the pairs of limiting members. The telescopic assembly includes a telescopic member, a load-bearing member, and a first drive member. The telescopic member extends along a second direction, and the load-bearing member is mounted on the telescopic member. The load-bearing member is provided with a limiting part, and the first drive member can drive the load-bearing member to move along the second direction. During the handling process, the load-bearing member first extends to pick up the goods, and then retracts. The handling AGV transports the goods to the target location. The handling AGV can free up handling personnel and improve handling efficiency. The limiting members and limiting parts limit the goods, reducing the risk of accidental slippage during handling. The handling AGV facilitates the handling of goods. However, the telescopic function in this solution cannot increase the storage space and cannot be used in conjunction with a balance vehicle.

[0004] Therefore, it is necessary to invent a device for the maintenance and handling of auxiliary power units to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a device for auxiliary power unit maintenance and transportation, so as to solve the problem that the device for maintenance and transportation of small aircraft engines has limited functionality and storage space.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for maintenance and handling of auxiliary power units includes a main body, a balance scooter, a lifting platform, a first storage platform, a second storage platform, and a base plate. The balance scooter is fixedly connected to the main body via connectors. A groove is provided on the inner side of the main body, and the bottom end of a folding frame is slidably connected within the groove. The top end of the folding frame is rotatably connected to the lifting platform. A telescopic rod is connected to the side of the lifting platform extending from the main body. The telescopic rod is composed of multiple sleeves of different diameters, which are arranged in a stepped manner. The telescopic rod passes through the first storage platform, the second storage platform, and the base plate in sequence.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] This invention improves the speed and directional flexibility of the device by combining omnidirectional wheels at the bottom of the main body with a balance scooter. The folding frame and lifting plate installed on the main body increase the storage space. The lifting plate is raised and lowered by extending and retracting the folding frame. During the raising process, the storage mechanism opens, increasing the storage space. As the lifting plate is continuously raised, the non-woven fabric on both sides extends out, sealing the two sides of the lifting plate and effectively preventing parts from accidentally entering. Furthermore, the continuous raising of the lifting plate sequentially lengthens the telescopic rods on both sides, raising and fixing the storage plates one and two in sequence. This fixes the space between the multiple storage plates, allowing for more components to be accommodated and improving the functionality of the main body of the device. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-5 The device shown is for maintenance and handling of auxiliary power units, including a main body 1, a balance scooter 2, a lifting platform 3, a first storage platform 4, a second storage platform 5, and a base storage plate 6. The balance scooter 2 is fixedly connected to the main body 1 via a connector 201. A groove 103 is provided on the inner side of the main body 1, and the bottom end of a folding frame 302 is slidably connected within the groove 103. The folding frame 302 can be a scissor-type folding frame. The top end of the folding frame 302 is rotatably connected to the lifting platform 3. The lifting platform 3 extends out of the side of the main body 1 and is connected to a telescopic rod 301. The telescopic rod 301 is composed of multiple sleeves of different diameters, which are arranged in a stepped manner. The telescopic rod 301 passes through the first storage platform 4, the second storage platform 5, and the base storage plate 6 in sequence. The main body 1 consists of a handle and multiple casters at the bottom, and both the casters and the balance scooter 2 are in direct contact with the ground. The main body 1 is made of stainless steel, and the lifting platform 3 is also made of stainless steel.

[0018] The main body of the equipment 1 can transport small aircraft generators that need maintenance, and can transport multiple generators in batches to improve the efficiency of transportation. It can also work with the balance vehicle 2 to improve the flexibility of movement speed and direction.

[0019] The equipment body 1 has cavities 101 on both sides of the bottom surface. A self-resetting shaft is installed in the cavity 101. One end of the non-woven fabric 102 is wound on the shaft. The other end of the non-woven fabric 102 is fixed to the bottom surface of the lifting plate 3. A pushing mechanism 303 is connected to the bottom side of the folding frame 302. The pushing shaft of the pushing mechanism 303 is parallel to the slide 103, and the length of the slide 103 is greater than the maximum pushing range of the pushing shaft of the pushing mechanism 303.

[0020] When the lifting plate 3 is raised, the non-woven fabric 102 is pulled out, sealing the side of the lifting plate 3 to prevent it from extending into the folding frame 302 when multiple small engines are placed, thus preventing damage to the folding frame 302.

[0021] The storage plate 4, storage plate 5, and storage base plate 6 have the same area, and the storage base plate 6 is fixedly connected to the main body 1 of the equipment. The storage plate 4, storage plate 5, and storage base plate 6 are provided on both sides of the main body 1 of the equipment, and the movement of the storage plate 4, storage plate 5, and storage base plate 6 on both sides is synchronized.

[0022] Storage plate 4, storage plate 5, and storage base plate 6 are raised sequentially by equal distances, allowing small engines to be placed in multiple equal spaces, thus increasing the transport space of the entire equipment body 1.

[0023] The storage plate 4, storage plate 5, and storage base plate 6 are placed horizontally. In order to facilitate the storage of each sub-component, corresponding receiving slots can be designed in the storage plate 4, storage plate 5, and storage base plate 6 by contouring.

[0024] During operation, the aircraft generator that needs maintenance is placed on the lifting platform 3, and it can be easily and quickly moved to the maintenance position by the main body of the equipment 1 and the balance vehicle 2, thus improving the efficiency of handling.

[0025] When there are many generators that need maintenance, the push mechanism 303 can be activated to raise the lifting plate 3. During the process of raising the lifting plate 3, the non-woven fabric 102 will be pulled open, which will cover the structure of the folding frame 302 and prevent foreign objects from falling into the folding frame 302 and affecting the recycling of the folding frame 302. As the non-woven fabric 102 is continuously pulled out, both sides of the lifting plate 3 are sealed. At the same time, the telescopic rods 301 on both sides of the lifting plate 3 are pulled out in sequence, and the storage plate 1 4 and storage plate 2 5 are raised in sequence, increasing the storage space of the main body of the equipment 1. At this time, multiple generators and corresponding sub-components can be placed on the main body of the equipment 1 at the same time.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
