[0029] The preferred embodiments of the utility model are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only for illustrating and understanding the utility model, and are not intended to limit the utility model.

[0030] The embodiment discloses a lightweight transport vehicle suitable for railway track, which can transport materials, tools or serve as a passenger vehicle during construction, thereby reducing the labor intensity of workers and improving the construction efficiency. Figure 1 As shown in Figure 2 The embodiment includes a vehicle body assembly, a wheel assembly and a control assembly assembled on the vehicle body assembly.

[0031] It should be noted that "left and right" in the embodiment is based on the left and right in Figures 1 to 4 The "front and back" in the embodiment is based on the direction of travel.

[0032] The vehicle body assembly is a split structure, as shown in Figure 3 And Figure 4As shown, the vehicle includes a left body 1 and a right body 2 connected by an insert fitting. The left body 1 and right body 2 have identical structures, each including a body frame made of square tubing and a panel fixed to the upper surface of the body frame. When the left body 1 and right body 2 are combined, their panels form the load-bearing surface of the vehicle assembly. To ensure structural strength while reducing vehicle weight, in this embodiment, both the left body 1 and right body 2 are made of 7-series aluminum alloy.

[0033] Furthermore, a first sleeve 3 is provided on the side of the left vehicle body 1 facing the right vehicle body 2, and a second sleeve 4 is provided on the side of the right vehicle body 2 facing the left vehicle body 1. The first sleeve 3 and the second sleeve 4 are compatible and can be inserted together. Specifically, as follows... Figure 3 and Figure 4 As shown, in this embodiment, the left car body 1 is provided with two first sleeves 3, and the right car body 2 is provided with two second sleeves 4 corresponding to the first sleeves 3. The inner diameter of the first sleeve 3 is the same as the outer diameter of the second sleeve 4. When the second sleeve 4 is inserted into the first sleeve 3, the distance between the bottom track wheel 5 of the left car body 1 and the bottom track wheel 5 of the right car body 2 is just adapted to the width of the railway track. It can be assembled on the railway track in this state. Moreover, under the restriction of the railway track, the track wheel 5 cannot move outward. Therefore, the left car body 1 will not detach from the right car body 2 even if it is connected by insertion.

[0034] Of course, the outer diameter of the first sleeve 3 can be the same as the inner diameter of the second sleeve 4, while increasing or decreasing the number of the first sleeve 3 and the second sleeve 4.

[0035] The wheel assembly is mounted at the bottom of the aforementioned body assembly to provide the vehicle body assembly with the function of moving. For example... Figure 2 and Figure 4 As shown, the wheel assembly includes four track wheels 5 located at the four corners of the vehicle body assembly, and at least one track wheel 5 integrates a hub motor. In this embodiment, the hub motor is integrated on only one of the track wheels 5, and the track wheel 6 with the integrated hub motor is mounted on the bottom of the left vehicle body 1, located on the rear side.

[0036] Furthermore, in this embodiment, all four track wheels 5 are assembled to the bottom of the vehicle body assembly via connecting plate assemblies. For example... Figure 5 and Figure 6 As shown, the connecting plate assembly includes two connecting plates 7 and two locking plates 10. The two connecting plates 7 are fixedly mounted relative to each other at the bottom of the vehicle body assembly. Each connecting plate 7 has an opening slot 8 at its bottom end for accommodating the axle of the track wheel 5, and a rectangular slot 9 at its top. The two locking plates 10 are respectively assembled at both ends of the axle of the track wheel 5, and the locking plates 10 are limited by nuts 13. In this embodiment, the locking plates 10 have an L-shaped structure.

[0037] like Figure 5As shown, the track wheel 5 is placed in the opening groove 8 of the two connecting plates 7, the locking piece 10 is hooked in the rectangular groove 9 of the corresponding connecting plate 7, and the locking piece 10 is located outside the connecting plate 7, then the nut 13 is screwed to make the locking piece 10 tightly fit with the connecting plate 7, so that the track wheel 5 is assembled at the bottom of the vehicle body assembly.

[0038] The control assembly is used to control the hub motor in the wheel assembly. In the embodiment, the control assembly comprises a controller 11 and a battery 12. The controller 11 is fixed on the bottom of the left vehicle body 1 through a waterproof cover, and the battery 12 is fixed on the bottom of the right vehicle body 2 through a pressing plate. In the embodiment, the battery 12 is a lithium battery, and is connected with the battery 12 through an aviation joint by a power line. The controller 11 in the embodiment is of a prior structure, and is internally provided with a Bluetooth module, which can be connected with a mobile phone Bluetooth, and the embodiment is remotely controlled through an APP.

[0039] According to actual needs, the controller 11 can be fixed on the bottom of the right vehicle body 2, and the battery 12 can be fixed on the bottom of the left vehicle body 1. In this case, the track wheel 6 integrated with the hub motor should be assembled at the bottom of the right vehicle body 2.

[0040] It should be noted that the battery 12 and the hub motor are both heavy, and the battery 12 and the hub motor are arranged separately, so that the weight of the vehicle body can be balanced. The controller 11 and the hub motor are arranged on the same vehicle body because there are many connecting lines between the controller 11 and the hub motor, so that the line layout is more convenient.

[0041] It should be noted that the above only describes preferred embodiments of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the above embodiments, and for those skilled in the art, the technical scheme recorded in the above embodiments can be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
