[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a mobile cleaning device for a cable tray of a coal conveying system, comprising a cleaning machine 1, a dust suction port and a roller brush are arranged at the bottom end of the cleaning machine 1, and the inside of the cable tray 20 can be cleaned. The outer periphery of the cleaning machine 1 is fixedly connected with a sliding support assembly that enables the cleaning machine 1 to slide along the upper surface of the cable tray 20. The sliding support assembly comprises a support frame 2 that supports the cleaning machine 1, the inner side of the support frame 2 is fixedly connected to the outer periphery of the cleaning machine 1, a rectangular groove 3 is opened on the top of the support frame 2, and two groups of rectangular grooves 3 are arranged, which are symmetrically arranged on the left and right sides of the support frame 2, and a supporting wheel 4 is arranged inside the rectangular groove 3, and the supporting wheel 4 is arranged in a plurality of groups, which are evenly distributed in a ring shape on the rectangular tray 2. Inside the groove 3, the bottom of the sliding support assembly contacts with the cable tray 20, which facilitates the cleaning machine 1 to slide on the top of the cable tray 20. The bottom end of the support wheel 4 contacts the top of the cable tray 20. The outside of the sliding support assembly is fixedly connected with a connecting column 5. There are two groups of connecting columns 5, which are symmetrically arranged on the left and right sides of the sliding support assembly. The outer periphery of the connecting column 5 is slidably connected with a connecting rod 6. The length of the connecting rod 6 can be selected according to the distance of the cable tray 20 from the ground. The inner side of the connecting rod 6 is fixedly connected with a limiting buckle 7, and the inner side of the connecting rod 6 is fixedly connected with a limiting cylinder 8. The outer periphery of the limiting cylinder 8 is slidably connected with a connecting circular tube 9, and the connecting circular tube 9 connects the left and right groups of connecting rods 6 together.

[0033] Reference Figure 3-Figure 4 A group of limit seats 10 are fixedly connected to both ends of the outer circumference of the connecting circular tube 9. A limit groove 11 is provided inside the limit seat 10. The inner wall of the bottom end of the limit groove 11 is elastically connected to the limit block 13 through a limit spring 12. When the limit block 13 is not subjected to force, the limit spring 12 will push the limit block 13 upward. One end of the limit spring 12 is fixedly connected to the inner wall of the bottom end of the limit groove 11, and the other end of the limit spring 12 is fixedly connected to the bottom end of the limit block 13. The outer circumference of the limit block 13 is slidably connected to the inside of the limit groove 11. The limit groove 11 limits the limit block 13 to slide only along the inner wall of the limit groove 11. The outer side of the limit block 13 is set to an inclined surface, which can convert part of the horizontal force into a downward force. The outer circumference of the limit block 13 is clamped in the inside of the limit buckle 7. The limit block 13 and the limit buckle 7 limit the left and right movement of the connecting rod 6, so that the connecting rod 6 cannot be separated from the connecting column 5.

[0034] Reference Figure 2 and Figure 5The bottom of the cleaning machine 1 is fixedly connected with a fixed seat 14, and the fixed seat 14 is provided with two groups, which are symmetrically arranged on the left and right sides of the cleaning machine 1. An adjustment groove 15 is opened inside the fixed seat 14, and a sliding block 17 is elastically connected to the inner side of the adjusting groove 15 through a return spring 16. When the sliding block 17 is not subjected to force, the return spring 16 will push the sliding block 17 to move outward. One end of the return spring 16 is fixedly connected to the inner side of the adjusting groove 15, and the other end of the return spring 16 is fixedly connected to the inner side of the sliding block 17. The outer periphery of the sliding block 17 is slidably connected to the inside of the adjusting groove 15. The adjusting groove 15 limits the sliding block 17 to slide left and right on the inner wall of the adjusting groove 15. The bottom end of the sliding block 17 is fixedly connected with a connecting bracket 18 that plays a fixed supporting role. An adjusting wheel 19 is provided at the bottom end of the connecting bracket 18. The adjusting wheel 19 is provided with multiple groups, which are linearly and evenly distributed at the bottom end of the connecting bracket 18. The outer side of the adjusting wheel 19 is connected to the inner wall of the side of the cable tray 20, so that the position of the cleaning machine 1 does not deflect when it moves.

[0035] Working principle: when you want to conveniently drive the cleaning machine 1 to move on the cable tray 20, slide the top of the connecting rod 6 into the interior of the connecting column 5, and then align the limit seats 10 at both ends of the connecting circular tube 9 with the limit buckles 7, align the openings at both ends of the connecting circular tube 9 with the limit cylinder 8, and insert the connecting circular tube 9. At this time, the outer inclined surface of the limit block 13 is in contact with the limit buckle 7, and the limit buckle 7 pushes the limit block 13 to make the limit block 13 slide into the interior of the limit seat 10. When the limit block 13 is opposite to the internal opening of the limit buckle 7, the limit block 13 is not subject to force at this time, and the limit spring 12 pushes the limit block 13 upward, so that the limit block 13 is inserted into the interior of the limit buckle 7. At this time, pull the connecting circular tube 9 to pull the support frame 2, and the support frame 2 drives the support wheel 4 to roll on the cable tray 20, thereby driving the cleaning machine 1 to slide on the cable tray 20 for cleaning. When the cleaning machine 1 is placed on the cable tray 20, first squeeze the connecting brackets 18 on both sides so that the connecting brackets 18 drive the sliding block 17 to move inward and compress the reset spring 16, and then place the cleaning machine 1 inside the upper groove of the cable tray 20, loosen the connecting bracket 18, and the reset spring 16 will push the sliding block 17 to move outward, and the sliding block 17 drives the connecting bracket 18 to move outward, and the connecting bracket 18 drives the adjusting wheel 19 to move outward, so that the adjusting wheel 19 contacts the side walls of the cable tray 20 on both sides. At this time, the supporting wheel 4 contacts the upper surface of the cable tray 20. At this time, when the cleaning machine 1 is pulled, the cleaning machine 1 can keep sliding in the same direction as the cable tray 20, and the moving direction will not deflect.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
