Description

Technical Field

[0001] The present application relates to the technical field of track construction, and in particular to a transport device that travels on a track plate. Background Art

[0002] Ballastless track refers to a track structure that uses an integral foundation such as concrete or asphalt mixture to replace the granular gravel roadbed.

[0003] After the (ballastless track) track slab installation is completed, fasteners still need to be transported in subsequent construction. However, due to the limitations of the track slab installation location, transportation vehicles can no longer be used. In addition, the subsequent construction requires a large number of materials and fasteners, and the construction route is long. If manual transportation is used, a large amount of manpower is required, and the construction efficiency is low. Utility Model Content

[0038] The present application is further described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 , an embodiment of the present application discloses a transport device that travels on a track plate, including a transport platform 1 and support wheels 21.

[0040] The transport platform 1 can be formed by welding square steel pipes, and steel plates can be laid on the frame formed by welding square steel pipes.

[0041] Reference Figure 2 and Figure 3 , support wheel 21 is connected to the transport platform 1. In the accompanying drawings, support wheel 21 is rotatably connected to the lower end of support rod 22, with the axis of support wheel 21 horizontal. Support wheel 21 is used to roll on the upper surface of track plate 0. The upper end of support rod 22 is connected to the lower end of transport platform 1, and angle steel 4 is welded between support rod 22 and transport platform 1 for reinforcement.

[0042] Reference Figure 1 and Figure 3 There are three groups of support wheels 21. Along the width direction of the track plate 0, the support wheels 21 of the middle group deviate from the midpoint of the transport platform 1 so that the support wheels 21 of the middle group are used to avoid the pouring holes 01 of the track plate 0.

[0043] Reference Figure 1 and Figure 3 , along the width direction of the track plate 0, both ends of the transport platform 1 extend out of the track plate 0. The transport device further includes a limiting member 3. The limiting member 3 includes a limiting rod 31 and a limiting wheel 32.

[0044] The upper end of the limiting rod 31 is connected to the transport platform 1, and the limiting wheel 32 is connected to the lower end of the limiting rod 31. The axis of the limiting wheel 32 is perpendicular to the axis of the supporting wheel 21, and the limiting wheel 32 is used to roll on the side surface of the track plate 0.

[0045] At the same time, when the limiting wheel 32 rolls on the side surface of the track plate 0 , the supporting wheel 21 avoids the rail support platform 02 of the track plate 0 , and the supporting wheel 21 avoids the pouring hole 01 of the track plate 0 .

[0046] There are four limiting members 3 , and the four limiting members 3 are in a rectangular array.

[0047] Along the axial direction of the support wheel 21, the distance between the two limiting members 3 is greater than the width of the track plate 0, and the difference between the distance between the two limiting members 3 and the width of the track plate 0 is 3 cm. Specifically, when one limiting wheel 32 abuts the side surface of the track plate 0, the distance between the other limiting wheel 32 and the side surface of the track plate 0 is 3 cm; that is, L = 3 cm in the figure.

[0048] And attached Figure 2 In the middle, angle steel 4 is welded between the limit rod 31 and the transport platform 1 for reinforcement.

[0049] The diameter of the support wheel 21 is larger than the diameter of the limiting wheel 32, which is conducive to smoothly crossing the expansion gap between the two track plates 0 and reducing bumps. In this embodiment: the diameter of the support wheel 21 is 200mm, and the diameter of the limiting wheel 32 is 100mm.

[0050] Reference Figure 1 , along the traveling direction of the transport device: both ends of the transport platform 1 are provided with connection holes 11. The connection holes 11 are used for connecting the pull rope.

[0051] Multiple transport devices can be connected by drawstrings to achieve intermodal transport.

[0052] The implementation principle of a transport device that travels on a track plate in an embodiment of the present application is as follows: during transportation, the limiter 3 limits the travel route to avoid damage to the rail support platform 02 and the pouring hole 01 of the track plate 0; a large-diameter support wheel 21 is used to smoothly cross the expansion joint between the two track plates 0 to reduce bumps; 3 cm is reserved to facilitate walking on curved sections; and the travel route is limited.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
