[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] like Figure 1 As shown, the utility model comprises a cable trough 1 and a running device 2 adapted thereto; the cable trough 1 can store auxiliary pipelines, cables, wires, etc., so that they are placed in the cable trough 1, thereby improving the safety of cable use.

[0041] One side of the cable trough 1 is fixedly connected to the middle trough 3, and the other side of the cable trough 1 is fixedly provided with an upper curved plate 41 and a transverse plate 42 arranged along the length direction of the middle trough 3. The transverse plate 42 is arranged below the upper curved plate 41 and there is a spacing between them. The transverse plate 42 is fixedly provided with a track 43 arranged along its length direction; the walking device 2 includes at least two wheels 51 adapted to the track 43, the two wheels 51 are arranged along the length direction of the middle trough 3, the two wheels 51 are arranged between the upper curved plate 41 and the transverse plate 42 and are vertically rotatably installed on the bearing mechanism 6, the bearing mechanism 6 is arranged on the outer side of the cable trough 1, and the bearing surface 61 of the bearing mechanism 6 is not higher than the top surface of the cable trough 1.

[0042] The wheel 51 extends from one end of the middle groove 3 between the upper curved plate 41 and the cross plate 42, and after being installed on the track 43, it can drive the outer supporting mechanism 6 to move along the length direction of the middle groove 3. During the movement of the supporting mechanism 6, it can drive the materials or workers to move together through the supporting surface 61 to achieve the transportation effect, which changes the traditional method of manually crawling to move or transport other components, improves the transportation efficiency, and reduces the transportation difficulty; moreover, in the utility model, the supporting surface 61 of the supporting mechanism 6 is not higher than the top surface of the cable trough 1. When the materials or workers are placed or lie on the supporting surface 61 for transportation, especially when transporting in a thin coal seam, its thickness is less than 1.3 meters, which reduces the upper space occupied by it, and facilitates the transportation of larger-sized materials, thereby expanding the transportable size range of the materials and increasing the transportation volume of the materials; at the same time, after the workers lie on the supporting surface 61, there is a distance between them and the top of the thin coal seam working surface, and they will not be scratched with it, which also improves the safety and stability of the workers' transportation.

[0043] like Figures 1 to 5 As shown together, preferably, the cable trough 1 includes a vertical plate 11 and a plurality of hook plates 12 arranged along the length direction of the middle trough 3, and the vertical plate 11 and the plurality of hook plates 12 are arranged opposite to each other; the vertical plate 11 is fixedly connected to the middle trough 3, and the bottom of the vertical plate 11 is fixedly connected to the plurality of hook plates 12 through the bottom plate 13, and the vertical plate 11, the bottom plate 13, and the plurality of hook plates 12 together form a placement space for accommodating cables; the plurality of hook plates 12 are arranged at intervals and are all in the same plane, and a discharge notch 14 for cleaning materials is formed between two adjacent hook plates 12, and a horizontal plate 42 is fixedly arranged on the outside of the hook plate 12. When coal slag and debris fall into the cable trough 1, they can be cleaned out through the discharge notch 14, which improves the convenience of cleaning and also improves the cleaning efficiency.

[0044] The hook plate 12 is provided with a plurality of waist holes 121 , and other auxiliary pipelines, cables and other wires that cannot be put in the cable trough can be auxiliary hung through the waist holes 121 .

[0045] A vertical plate 15 is fixedly provided on the inner side of the hook plate 12 . The positions and quantities of the vertical plates 15 correspond to those of the hook plate 12 . There is a spacing between the vertical plates 15 and the hook plate 12 . The two ends of the vertical plates 15 are arranged in arc shape along the length direction of the middle groove 3 .

[0046] There is a gap between the vertical plate 15 and the hook plate 12, which can easily accommodate the connection of the auxiliary pipeline hung on the waist hole 121, prevent it from causing wear to the cables in the cable trough 1, and improve the safety of use. The two ends of the vertical plate 15 are set to be arc-shaped to prevent the two ends from scratching the cables in the cable trough 1 when the cables are dragged, thereby improving the service life and safety of the cables.

[0047] Position holes 111 are provided on the vertical plate 11, and a plurality of ribs 16 are fixedly provided between the bottom plate 13 and the vertical plate 11 along the length direction of the middle groove 3. The provision of the ribs 16 improves the connection strength between the vertical plate 11 and the bottom plate 13, and also improves the stability of the walking device 2.

The outer side of the movable vertical plate 62 is fixedly connected to the supporting plate 64 through a connecting member 63, and there is a spacing between the movable vertical plate 62 and the supporting plate 64.

[0049] A guide wheel 65 is installed on the movable upright plate 62 for transverse rotation; along the width direction of the middle groove 3, the outer end of the upper curved plate 41 is bent downward to form a limit portion 411, which is arranged between the movable upright plate 62 and the bearing plate 64, and is matched with the guide wheel 65. When the bearing mechanism 6 is driven by the two wheels 51 to move along the length direction of the middle groove 3, the limit portion 411 and the guide wheel 65 are rollingly matched, and the two wheels 51 are restricted from shaking by the limit portion 411, thereby improving the stability of the movement of the bearing mechanism 6.

[0050] The bottom of the bearing plate 64 is bent toward the side away from the middle groove 3 to form an integral bearing portion 641, and the upper surface of the bearing portion 641 is defined as the bearing surface 61; the top of the bearing plate 64 is fixedly connected to a horizontally arranged top plate 66, and the top plate 66 is arranged above the upper curved plate 41. The top plate 66 blocks the upper part of the upper curved plate 41 to prevent coal slag from falling near the wheel 51, thereby improving the moving effect of the wheel 51.
