In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] Example:

[0031] Reference Figures 1-4This utility model provides a cable tray for a roadheader's secondary transport system, comprising a cable bed 1, a first mounting frame 2 fixedly installed on the cable bed 1, a roadheader secondary transport body 21 mounted on the cable bed 1, and a second mounting frame 3 mounted on the roadheader secondary transport body 21. The first mounting frame 2 has a first pulley 4 at its top and a second pulley 5 on its inner wall. The second mounting frame 3 has a third pulley 6 at its top and a fourth pulley 7 on its inner wall. A fifth pulley 8 is mounted on the upper surface of the cable bed 1, and a closed steel wire 11 is mounted on the fifth pulley 8. Bases 9 are fixedly connected to the bottom of both the first mounting frame 2 and the second mounting frame 3. Through holes 10 are opened on the surface of each base 9. Sliders 12 are mounted on the closed steel wire 11, and connecting plates 13 are mounted on the sliders 12. Symmetrically distributed hook holes 14 are opened on the surface of the connecting plates 13, and protective rings 15 are fixedly connected to the inner walls of the hook holes 14. The protective rings 15 lift the hook holes 14. The wear resistance of 4 is beneficial to improving the service life of hook hole 14. A connection hole 16 is opened at the center of the connecting plate 13. An elastic ring 17 is fixedly connected to the inner wall of the connection hole 16. The cable body 20 is provided on the inner wall of the elastic ring 17. When the cable body 20 passes through the elastic ring 17, the elastic ring 17 undergoes elastic deformation, thereby tightening the cable body 20 and making it difficult for the cable body 20 to slide in the connection hole 16. A rope slacker 18 is fixedly connected to the side of the first mounting frame 2. A steel cable 19 is also fixedly connected to the surface of the rope slacker 18. One end of the steel cable 19 is fixedly connected to the cable bed 1. A steel rope 22 is fixedly connected to the side of the second mounting frame 3. The surface of the secondary transport body 21 of the roadheader is fixedly connected to the steel rope 22. One end of the closed steel wire 11 starts from the secondary transport body 21 of the roadheader. The closed steel wire 11 passes through the fifth pulley 8, the third pulley 6, the fourth pulley 7, the first pulley 4 and the second pulley 5 and is fixed to the secondary transport body 21 of the roadheader.

[0032] In this embodiment, refer to Figures 1-4 Using the first pulley 4, second pulley 5, third pulley 6, and fourth pulley 7 on the first mounting frame 2 and the second mounting frame 3, as well as a separate fifth pulley 8, the closed steel wire 11 forms a closed loop. As the second mounting frame 3 moves along with the main body 21 of the roadheader, the cable body 20 moves accordingly, forming a self-expanding and contracting motion. There is no need to worry about the cable dragging on the ground, and the cable is not easy to slip off. The roadheader can move freely. The first mounting frame 2 is secured with a rope slacker 18 and a steel cable 19, and the second mounting frame 3 is secured with a steel cable 22 to prevent the column from tilting due to the force of the cable body 20's expansion and contraction. This device has high reusability and strong practicality.

[0033] Working principle: The first pulley 4, the second pulley 5, the third pulley 6, and the fourth pulley 7 on the first mounting frame 2 and the second mounting frame 3, as well as a separate fifth pulley 8, form a closed loop with the closed steel wire 11. As the second mounting frame 3 moves along with the main body 21 of the roadheader, the cable body 20 moves accordingly, forming a self-expanding and contracting motion. There is no need to worry about the cable dragging on the ground, and the cable is not easy to slip off. The roadheader can retract and extend the cable freely.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
