Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, specifically a guide wheel and a multi-wheel rail-changing vehicle for a rail-changing vehicle. Background Technology

[0002] Due to their considerable length, production line moving platforms are typically equipped with multiple sets of wheels. Considering factors such as wheel installation deviations and track straightness, a large gap is left between the wheels and the track to reduce processing and installation accuracy requirements. While this ensures all wheels can smoothly run on the track, when using a sliding contact line power supply, this gap causes the moving platform to wobble laterally during movement. This wobble severely affects the lifespan of the sliding contact line and significantly increases the failure rate of the sliding contact line power supply. Therefore, guide wheels need to be added to both the front and rear ends of the moving platform to limit its wobble.

[0003] Currently, the common method to limit sway is to add horizontal guide wheels at both ends of the wheel set. This design relies on two horizontal guide wheels to clamp the track, forcing the moving platform to move along the center line of the track, thereby effectively suppressing sway. For platforms that run continuously on the same track, the horizontal guide wheels can provide good guidance.

[0004] However, for mobile platforms that use a lifting-type rail changing mechanism, when the platform is lifted as a whole and then lowered onto another set of tracks, the original horizontal guide wheels lack vertical guiding function due to possible positioning errors. This can easily cause the horizontal guide wheels to fail to accurately return to their predetermined positions or even get stuck on the tracks, making it impossible to quickly complete the rail changing and seating operation. Manual intervention is required for adjustment, which greatly reduces work efficiency. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a guide wheel for a track-changing vehicle and a multi-wheel track-changing vehicle.

[0006] To achieve the above objectives, this utility model provides a guide wheel for a track-changing vehicle, comprising a wheel body with a rotating structure. The side wall of the wheel body is provided with a first wheel groove for engaging with a track. The first wheel groove is radially divided along the wheel body from the inside to the outside into:

[0007] The traveling guide section is used to guide the guide wheel as it travels on the track;

[0008] The vertical guide section has a flared structure and is used for vertical guidance during the guide wheel rail changing.

[0009] In one embodiment, the first wheel groove is formed by a groove bottom wall and a first groove side wall and a second groove side wall disposed on both sides of the groove bottom wall;

[0037] Example 1

[0038] like Figure 1 The figure shown is a guide wheel (hereinafter referred to as "guide wheel") for a track changing vehicle disclosed in this embodiment. It mainly includes a wheel body 1 with a rotating body structure. The side wall of the wheel body 1 is provided with a first wheel groove 2 for cooperating with the track 3. The first wheel groove 2 is divided into a traveling guide section 201 and a vertical guide section 202 along the radial direction from the inside to the outside of the wheel body 1. The vertical guide section 202 has a flared structure.

[0039] refer to Figure 2 When the guide wheel travels normally on the track 3, the traveling guide section 201 has a small fitting gap (e.g., 1mm~2mm) between it and the two sides of the track 3, which is used to guide the guide wheel during its travel on the track 3.

[0040] refer to Figure 3 When the guide wheel changes track, since the vertical guide section 202 has a flared structure, when the falling position of the guide wheel deviates from that of the track 3, the position of the guide wheel can be corrected by the vertical guide section 202, so that the track 3 can be properly embedded into the traveling guide section 201, thus realizing vertical guidance when the guide wheel changes track.

[0041] In this embodiment, the guide wheel is provided with a first wheel groove 2 that expands outward from the travel guide section 201 and the vertical guide section 202 on the side wall. This allows it to provide guidance during normal travel and also to provide vertical guidance during the track changing descent process. This makes the positioning accuracy requirement of the track changing vehicle lower and the descent process smoother.

[0042] In the specific implementation process, the first wheel groove 2 is formed by the groove bottom wall 4 and the first groove side wall 5 and the second groove side wall 6 located on both sides of the groove bottom wall 4. The first end of the first groove side wall 5 is connected to the corresponding side of the groove bottom wall 4, and the second end of the first groove side wall 5 extends radially along the wheel body 1. The travel guide section 201 is located between the two first groove side walls 5. The second groove side wall 6 is connected to the second end of the corresponding side of the first groove side wall 5, and the second end of the second groove side wall 6 is inclined towards the corresponding side end wall on the wheel body 1, that is, the vertical guide section 202 is located between the two second groove side walls 6.

[0043] In a preferred embodiment, the first groove sidewall 5 and the second groove sidewall 6 are connected by an arc transition, thereby preventing the guide wheel from scraping against the track 3 during vertical guidance.

[0044] In a preferred embodiment, the bottom wall 4 of the groove and the side wall 5 of the first groove are connected by an arc, so as to match the chamfer at the top of the track 3.

[0045] In practical applications, the guide wheel in this embodiment can be obtained by directly adjusting the existing conventional running wheels without adding any additional accessories, resulting in a simpler structure and lower cost.

[0046] Example 2

[0047] This embodiment discloses a multi-wheel track-changing vehicle, which mainly includes a vehicle body 7. Guide wheels 8, as described in Embodiment 1, are rotatably connected to both ends of the bottom of the vehicle body 7. Figure 4 As shown, this effectively ensures that the multi-wheeled rail-changing vehicle can travel normally on track 3, and also enables vertical guidance during rail changing, resulting in lower positioning accuracy requirements and smoother descent during rail changing.

[0048] Example 3

[0049] This embodiment discloses a multi-wheeled track-changing vehicle, the implementation of which is basically the same as that of Embodiment 2, the only difference being that the multi-wheeled track-changing vehicle in Embodiment 2 is shorter, requiring only two sets of wheels. In this embodiment, the multi-wheeled track-changing vehicle is longer. In addition to the guide wheels 8 rotatably connected to both ends of the bottom of the vehicle body 7 as in Embodiment 1, at least one traveling wheel 9 is also rotatably connected to the bottom of the vehicle body 7. The traveling wheel 9 is located between the two sets of guide wheels 8, and when there are two or more traveling wheels 9, they are spaced apart along the length of the vehicle body 7. Figure 5 As shown.

[0050] refer to Figure 6 The side wall of the traveling wheel 9 is provided with a second wheel groove 901 that can mate with the track 3, and the groove depth of the second wheel groove 901 is less than that of the first wheel groove 2, so as to reduce the processing cost of the traveling wheel 9. At the same time, the groove width of the second wheel groove 901 is greater than that of the traveling guide section 201, for reference. Figure 7 When the multi-wheel track-changing vehicle travels normally on track 3, the gap between the traveling guide section 201 and the two sides of track 3 is about 1mm to 2mm, while the gap between the second wheel groove 901 and the two sides of track 3 is about 3mm to 5mm, thereby effectively reducing the processing accuracy and assembly requirements of the traveling wheel 9.

[0051] refer to Figure 8 When the multi-wheeled rail-changing vehicle changes rails and its falling position deviates from that of the track 3, the position of the guide wheel 8 and the traveling wheel 9 is corrected by the vertical guide section 202 with the flared structure, so that the track 3 can be properly embedded into the traveling guide section 201 and the second wheel groove 901, thus realizing the vertical guidance of the multi-wheeled rail-changing vehicle when changing rails.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
