The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides a cable hanging bracket for the roof of a coal mine roadway, such as... Figure 1-3 As shown, the device includes a fixed frame 1, with two sets of hangers 2 mounted on the top of the fixed frame 1. A sliding groove is formed on the surface of the fixed frame 1, and a sliding sleeve 3 is slidably installed in the groove. Limiting holes are evenly spaced in the sliding groove of the fixed frame 1. A limiting bracket 4 is installed on the front side of the sliding sleeve 3. A connecting plate 5 is installed at the lower end of the limiting bracket 4. A positioning plate 6 is installed on the lower side of the connecting plate 5. An open sliding groove is provided on the lower side of the connecting plate 5. The positioning plate 6 is slidably installed on the lower side of the connecting plate 5. A fixing bolt 7 is installed on the side of the connecting plate 5. Positioning grooves are evenly spaced on the side wall of the positioning plate 6. A hook 8 is installed on the lower side of the positioning plate 6. A limiting pin 9 is installed on the side of the hook 8. When in use, the hanger 2 can be installed on the top of the coal mine roadway, and then the cable can be hung on the inside of the hook 8. The cable is limited by the limiting pin 9 on the side of the hook 8, thereby realizing the cable hanging. The device is equipped with a sliding sleeve 3, which is slidably installed on the fixed frame 1 and limited by the limiting frame 4. This setting allows the horizontal position of the hook 8 to be adjusted. The positioning plate 6 is slidably installed on the lower side of the connecting plate 5 and limited and fixed by the fixing bolt 7. This setting allows the height of the hook 8 to be adjusted. Through multiple adjustments, the bracket can be used more flexibly, improving the applicability of the device.

[0020] Five sets of sliding sleeves 3 are provided. All five sets of sliding sleeves 3 are slidably installed on the surface of the fixed frame 1. By setting five sets of sliding sleeves 3, multiple cables can be limited at one time, and the cables can be laid in an orderly manner to avoid tangling between the cables.

[0021] The limiting frame 4 has a groove inside, and a pull rod 10 is slidably inserted into the groove. A locking block 11 is installed at the inner end of the pull rod 10, and a first spring 12 is sleeved on the outside of the pull rod 10. The locking block 11 is inserted into the limiting hole in the slide groove of the fixing frame 1. With the pull rod 10 and the locking block 11, the locking block 11 is locked into the limiting hole of the fixing frame 1 under the elastic force of the first spring 12. The pull rod 10 can be pulled to pull the locking block 11 out of the limiting hole and move the slide sleeve 3. This limiting method is simple and easy to operate, making the horizontal adjustment of the hook 8 more convenient.

[0022] A groove is provided on the upper right side of the hook 8, and a connecting rod 13 is slidably inserted into the groove. A washer 14 is slidably installed on the inner end of the connecting rod 13, and a second spring 15 is sleeved on the outside of the connecting rod 13. A limiting pin 9 is installed on the lower side of the washer 14. By setting the connecting rod 13 and the second spring 15, the elastic force generated by the second spring 15 on the washer 14 causes the limiting pin 9 to be engaged in the groove on the surface of the hook 8. When in use, the connecting rod 13 can be pulled to pull the limiting pin 9 upward to put the cable in. This operation method makes the installation and removal of the cable more convenient.

[0023] The inner side of the limiting pin 9 is set as an arc surface. When the cable shakes, it will exert pressure on the limiting pin 9. By setting the inner side of the limiting pin 9 as an arc surface, the limiting pin 9 will not be dislodged when the cable is close to the limiting pin 9, thereby preventing the cable from falling off.

[0024] The inner wall of the hook 8 is equipped with a protective pad 16. By installing the protective pad 16 at the bottom of the hook 8, damage caused by friction with the cable can be avoided.
