The top of the active side connection unit 220 is detachably and fixedly connected to the bottom of the active side rotation unit 210, and the bottom of the active side connection unit 220 is used to slide with the corresponding track. Since the bottom of the active side rotation unit 210 can rotate around its vertical axis, the active side walking module 200 can adapt to curves of different radii when traveling along the track.

[0027] As a preferred embodiment, please refer to Figure 2 The active side rotation unit 210 includes an active side bearing assembly 211 and an active side mounting plate 212. The axis of the active side bearing assembly 211 is vertically arranged. The fixed part of the active side bearing assembly 211 is detachably and fixedly connected to the frame 100. The active side mounting plate 212 is disposed at the bottom of the active side bearing assembly 211 and is fixedly connected to the rotating part of the active side bearing assembly 211. The top of the active side connecting unit 220 is detachably and fixedly connected to the active side mounting plate 212, thereby allowing the active side connecting unit 220 to rotate freely relative to the frame 100, and thus enabling the active side walking module 200 to adapt to curves of different radii when traveling along the track.

[0031] As a preferred embodiment, please refer to Figure 3The driven-side rotating unit 320 includes a driven-side bearing assembly 321 and a driven-side mounting plate 322.

The top of the driven-side connecting unit 330 is detachably and fixedly connected to the driven-side mounting plate 322, thereby allowing the driven-side connecting unit 330 to rotate freely relative to the frame 100, and thus enabling the driven-side traveling module 300 to adapt to curves of different radii when traveling along the track.

[0032] As a preferred embodiment, please refer to Figure 3 The driven-side connection unit 330 includes a driven-side wheel box 331, at least two driven-side fixing plates 332, and multiple driven-side guide wheels 333.

[0033] As a preferred embodiment, please refer to Figure 1 The active side walking module 200 includes multiple active side walking modules 200, each of which is spaced apart along the length direction of the corresponding track. The active side walking module 200 can be configured as two according to the size of the frame 100, and respectively arranged at the front and rear ends of the frame 100 to improve the support effect on the frame 100.

[0035] To better understand this utility model, the following is combined with... Figure 1 - Figure 3The working principle of the technical solution of this utility model will be described in detail below:

[0036] In use, the active-side guide wheels 223 on the active-side walking module 200 are respectively arranged on both sides of one track. At this time, each active-side guide wheel 223 is in rolling connection with the sidewall of the corresponding track. Similarly, the driven-side guide wheels 333 on the driven-side walking module 300 are respectively arranged on both sides of the other track. Again, each driven-side guide wheel 333 is in rolling connection with the sidewall of the corresponding track. This prevents the RGV from derailing during operation. The active-side guide wheels 223 on the active-side walking module 200 and the driven-side guide wheels 333 on the driven-side walking module 300... All wheels 333 can travel along their corresponding tracks. When the RGV track gauge is different, each slider 312 on the driven side walking module 300 slides in its corresponding guide rail 311, causing the moving plate 313 to move within the length range of the guide rail 311. This adjusts the distance between the driven side walking module 300 and the active side walking module 200 to adapt to different RGV track gauges. This adaptive track gauge RGV body structure can adapt to multiple RGV track gauges. Each time the track gauge is changed, it is no longer necessary to remake the RGV body. It has versatility, which can save time, reduce costs, and meet various customer needs.

[0037] The adaptive gauge RGV body structure provided by this utility model has the following beneficial effects:

[0038] (1) The arrangement of the active side bearing assembly 211 and the driven side bearing assembly 321 allows the active side walking module 200 and the driven side walking module 300 to rotate freely relative to the frame 100, thereby enabling the active side walking module 200 and the driven side walking module 300 to adapt to curves of different radii when traveling along the track.

[0039] (2) Each of the active side guide wheels 223 is rolledly connected to the side wall of the corresponding track, and each of the driven side guide wheels 333 is rolledly connected to the side wall of the corresponding track, which can prevent the RGV from derailing during operation.

[0040] (3) The adaptive gauge RGV car body structure can adapt to various RGV gauges. Each time the gauge is changed, there is no need to remake the RGV car body. It has versatility, which can save time, reduce costs and meet the various needs of customers.
