Here, the longitudinal direction of the mounting structure 2 refers to the X-axis direction in fig. 1.

A suspended air rail train generally comprises a bogie and a vehicle body, wherein the bogie is connected with the roof of the vehicle body, and the roof of the vehicle body is used for bearing electrical equipment such as a storage battery, an air conditioner and the like besides being connected with the bogie. In the present embodiment, the mounting structure 2 is provided on the roof body 1, and the connecting groove 23 with an upward opening is provided on the mounting structure 2. Therefore, when the electrical equipment is installed on the roof, the T-shaped bolt slides into the connecting groove 23 from the end part of the connecting groove 23 in a posture that the head part of the T-shaped bolt faces downwards, and the T-shaped bolt can slide in the connecting groove 23 along the length direction of the connecting groove 23 (namely the X-axis direction in the figure 1) so as to adjust the installation position of the electrical equipment, so that the flexibility and the convenience in installation of the electrical equipment are greatly improved; after the installation position of the electrical equipment is adjusted to a proper installation position, the installation hole in the electrical equipment is aligned to the T-shaped bolt and is simultaneously screwed down by the nut, so that the installation of the electrical equipment is completed, the installation difficulty of the electrical equipment is effectively reduced, and the installation efficiency can be improved.

Alternatively, the attachment slot 23 may have an inverted T-shape or cross-shape in an orthogonal projection on a plane perpendicular to the length direction of the mounting structure 2. That is, the orthogonal projection of the connecting groove 23 on the plane parallel to ZY in fig. 1 is in the shape of an inverted T or cross, or the cross section of the connecting groove 23 is in the shape of an inverted T or cross. So, set up spread groove 23 into inverted T-shaped groove or cross-shaped groove to conveniently utilize the cell wall in inverted T-shaped groove or cross-shaped groove to carry on spacingly to the bolt head of T type bolt, prevent T type bolt at spread groove 23 internal rotation, guarantee electrical equipment through spread groove 23 and the steadiness when T type bolt cooperation installation is fixed on the roof.

Alternatively, as shown in fig. 1, the mounting structure 2 includes a first profile bracket 21 and a second profile bracket 22 each provided with a connecting groove 23, the second profile bracket 22 is provided at both ends of the roof body 1 in the width direction, the first profile bracket 21 is located at one side or both sides of the second profile bracket 22 in the length direction, and the size of the second profile bracket 22 is larger than that of the first profile bracket 21 in the length direction of the mounting structure 2. Wherein, the width direction of the roof body 1 refers to the Y-axis direction in fig. 1, the length direction of the second profile bracket 22 refers to the X-axis direction in fig. 1, and the length direction of the mounting structure 2 is also the length direction of the first and

second profile brackets

21 and 22, that is, the length of the second profile bracket 22 is greater than the length of the first profile bracket 21.

Because the volumes of electrical equipment such as air conditioners, storage batteries and the like are different, and the installation positions are also different, the installation structure 2 using the same specification cannot meet the installation requirements of all the electrical equipment on the roof structure, so the installation structure 2 is divided into the first profile bracket 21 and the second profile bracket 22 in the embodiment to adapt to the installation requirements of different electrical equipment. Specifically, the second profile brackets 22 are disposed at both left and right ends of the roof body 1, and the first profile brackets 21 are located at the front and/or rear sides of the second profile brackets 22, for example, in one embodiment, each of the first profile brackets 21 and the second profile brackets 22 is provided in plural, the plural first profile brackets 21 are distributed at the front half of the roof body 1, and the plural second profile brackets 22 are distributed at the rear half of the roof body 1, that is, the first profile brackets 21 are distributed at the front side of the second profile brackets 22. In this embodiment, at least two profile brackets are required for mounting and fixing an electrical apparatus, the shorter first profile bracket 21 may be used to mount an electrical apparatus with a smaller volume (e.g., a distribution box, a storage battery, etc.), and the longer second profile bracket 22 has a larger contact area with the electrical apparatus, so that the second profile bracket 22 can provide a larger supporting force for the electrical apparatus, and can be used to mount an electrical apparatus with a larger volume (e.g., an air conditioner). So, can choose to adopt first section bar support 21 or second section bar support 22 to install fixedly according to electrical equipment's volume size, can prevent to all adopt longer second section bar support 22 to cause the waste of the production material of mounting structure 2 when installing small electrical equipment, also can prevent to all adopt shorter first section bar support 21 to cause first section bar support 21 to be not enough for the holding power that electrical equipment provided when installing large electrical equipment, lead to bulky electrical equipment to install insecure.
