The rail-mounted trolley 110 is mounted on the rail 120, and when the rail-mounted trolley 110 is in the first state, each guide wheel assembly 30 is spaced from its corresponding connecting plate 121 b. As shown in fig. 2, the rail-mounted trolley 110 is mounted on the rail 120, and when the rail-mounted trolley 110 is in the second state, the guide wheels 32 of each guide wheel assembly 30 are abutted against the inner side wall surface 125 of the rail 120 and can roll along the corresponding inner side wall surface 125. The plurality of road wheels 40 of the rail transportation trolley 110 are placed on the running surface 123 of the rail 120 and can roll on the running surface 123.

Further, when the rail transit car 110 is mounted to the rail 120, the main body portion 11 of the car body 10 is disposed at a distance from the cable mounting 124 of the rail 120 in the height direction of the rail transit device 100, so as to avoid damage to the electric wires in the rail 120 due to collision of the car body 10 of the rail transit car 110 with the cable mounting 124. The road wheel 40 is placed on the road surface 123 and is operable on the road surface 123.

It will be appreciated that since the road wheels 40 may be universal wheels, this arrangement may provide flexibility in steering the rail car 110 as it travels over the track 120 through turns or turnout branches of the track 120. In addition, when the rail transportation trolley 110 travels in the rail 120, the plurality of traveling wheels 40 are used in cooperation with the plurality of guide wheels 32, and the plurality of traveling wheels 40 can play a role in stabilizing the rail transportation trolley 110 and assisting the rail transportation trolley 110 in guiding in a curve, so that the rail transportation trolley 110 can stably and safely travel in the rail 120, and further the use reliability of the rail transportation trolley 110 can be improved.

In this embodiment, when it is desired to transport material to a maintenance location of the track 120, a maintenance person may first place the track-truck 110 in the first state in the channel 122 of the track 120. The guide wheel assembly 30 is then unfolded with respect to the vehicle body 10, the plurality of locking members 70 are rotated, and at least a portion of each locking member 70 is caught by one of the first fixing portions 314, so that the guide wheel assembly 30 can be maintained in the unfolded state, so that the rail wagon 110 can be stably placed in the rail 120. At this point, material may be loaded into the rail transport cart 110. Finally, pushing the push handle 50 causes the rail wagon 110 to travel in the rail 120. When it is desired to remove the rail transit car 110 from the rail 120, the locking members 70 are rotated first such that each locking member 70 is spaced from the first securing portion 314, thereby enabling the guide wheel assembly 30 to be folded relative to the car body 10. At this time, the rail transport trolley 110 may be taken out of the rail 120.

According to the rail transportation trolley 110 provided by the utility model, the guide wheel assembly 30 is arranged, and the guide wheel assembly 30 can be unfolded or folded relative to the trolley body 10, so that the rail transportation trolley 110 can be conveniently collected and placed in the rail 120, the operation is simple and convenient, and the improvement of the working efficiency is facilitated. In addition, when the track 120 needs maintenance, maintenance personnel only need to transport materials to a specific position beside the track 120, and then the materials are loaded and transported by directly utilizing the track transport trolley 110, and large-scale transport equipment such as ground engineering vehicles and cranes are not needed, so that the maintenance cost of the track 120 can be reduced, the economy is good, and safety problems caused by operating the large-scale transport equipment can be avoided, thereby being beneficial to improving the safety.

The foregoing has outlined rather broadly the more detailed description of embodiments of the utility model, wherein the principles and embodiments of the utility model are explained in detail using specific examples, the above examples being provided solely to facilitate the understanding of the method and core concepts of the utility model; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present utility model, the present description should not be construed as limiting the present utility model in view of the above.
