Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground transportation equipment, and in particular to a small-turning-radius rail transport flatbed vehicle with wheelset linkage. Background Technology
[0002] Currently, most flatbed trucks used for rail transport in underground mines employ a fixed wheelset structure. While this design is relatively stable on straight tracks, it reveals significant limitations on curved sections, especially in situations requiring small-radius turns. The complex underground environment, with its frequent slope turns, makes derailment and off-tracking at small turning radii a serious threat to personnel and equipment safety, impacting transport efficiency.
[0003] To address the above issues, some improved models have emerged on the market, featuring wheelsets designed to rotate freely around a vertical axis. While this design solves the problems to some extent, its drawbacks are also significant. The front and rear wheelsets operate completely independently, making the vehicle prone to swaying or jamming when traversing switches or uneven sections of track. This results in unstable trajectory, reduced reliability, and increased safety risks.
[0004] There is currently no corresponding solution to the above problems. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a small turning radius rail transport flatbed with simple structure, free steering of wheelsets, balance of front and rear wheelsets through linkage, and smooth running trajectory.
[0006] The equipment includes a vehicle body, which serves as the assembly base for the equipment. Wheelsets are rotatably mounted on the front and rear parts of the vehicle body, respectively. The wheelsets are provided with two stabilizing links, which are hinged to each other on both sides of the two wheelsets in a cross arrangement.
[0007] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 2 As shown, when the vehicle body is running smoothly, the wheelsets run smoothly based on the track. When encountering a turn, especially when the turning radius is small, the two wheelsets respectively conform to their corresponding tracks and rotate based on the track. Furthermore, based on the configuration of the smoothing linkage, it can ensure that the front and rear wheelsets reduce sway or reduce the amplitude of sway in special road conditions such as bumps and intersections, reduce the overall vibration of the vehicle body, and ensure a smooth and continuous journey.
[0008] The beneficial effects of this utility model are: This utility model solves the problem that flatbed carts are prone to derailment when making small-radius turns in the prior art. Based on the rotation of the double wheelset, it achieves a close fit and adaptation to the track, avoiding derailment; in particular, a smoothing linkage is also configured between the two wheelsets, which can reduce the sway or amplitude of the wheelset, making the vehicle run more smoothly. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of a small-turning-radius rail transport flatbed vehicle with wheelset linkage as described in this utility model; Figure 2 This is a schematic diagram of an embodiment of a small-turning-radius rail transport flatbed vehicle with wheelset linkage according to the present invention; Figure label: 1-Wheelset 2-Wheelset support frame 3-Smooth link 4-Body 5-Connecting axle The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0010] Reference Figure 1 , Figure 2 The present invention provides a small turning radius rail transport flatbed vehicle with wheelset linkage, comprising a vehicle body 4, which is the assembly base of the equipment. Wheel sets 1 are rotatably installed at the front and rear of the vehicle body 4, respectively. A smoothing link 3 is provided between the wheelsets 1. There are a total of two smoothing links 3, which are hinged to each other on both sides of the two wheelsets 1 in a cross arrangement.
[0011] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 2 As shown, when the vehicle body 4 is running smoothly, the wheel set 1 runs smoothly based on the track. When encountering a turn, especially when the turning radius is small, the two wheel sets 1 respectively conform to their corresponding tracks and rotate based on the track turning. Based on the configuration of the smoothing linkage 3, it can ensure that the front and rear wheel sets 1 reduce sway or reduce the amplitude of sway in special road conditions such as bumps and intersections, reduce the overall vibration of the vehicle body 4, and ensure smooth and easy travel.
[0012] In Example 1, the vehicle body 4 is a flat plate, and traction lugs are respectively provided at the front and rear.
[0013] The aforementioned structure will be applied to underground flatbed trucks.
[0014] In Example 2, a connecting shaft 5 is provided under the vehicle body 4. The connecting shaft 5 is in the form of a male-female joint or a bearing. The wheelset 1 is rotatably connected to the vehicle body 4 through the connecting shaft 5.
[0015] This ensures that its rotational stroke is smooth, stable, and consistent.
[0016] In Example 3, the wheelset 1 includes a wheelset support frame 2, which is integrally formed. Mounting holes are provided on both sides of the wheelset support frame 2, and a traveling wheel is rotatably mounted in each of the two mounting holes through a wheel axle. The wheelset support frame 2 is rotatably connected to the vehicle body 4.
[0017] Furthermore, the wheelset support frame 2 is made of thick-walled steel plate.
[0018] The effect achieved is that, unlike the traditional mine car wheelset 1 which is based on a direct connection between the wheel and axle, this equipment is based on the synchronous assembly of two traveling wheels on the wheelset support frame 2, that is, the two traveling wheels are formed into wheelset 1 based on the wheelset support frame 2. On the one hand, it has higher operating strength, and on the other hand, it is more convenient to assemble, that is, it is easier to realize the rotational connection assembly between the car body 4 and the wheelset 1.
[0019] Furthermore, the stabilizing link 3 is positioned on the upper side of the opposite side of the two wheelset support frames 2; the two stabilizing links 3 are arranged crosswise and overlap vertically, and are positioned close to each other.
[0020] This achieves the effect of avoiding mechanical interference and facilitating assembly.
[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
