[0024] 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.

[0025] Reference Figure 1-5The utility model provides an embodiment: a cable protection device for coal mining equipment, comprising a base 1, a rotating shaft 8 is rotatably connected to the right end of the inner wall of the base 1, a connecting hole 7 is opened at the left end of the base 1, a threaded rod 6 is connected to the connecting hole 7 by threading, a first bevel gear 9 is meshed with a second bevel gear 10 on the outer diameter, a rotating shaft 11 is fixedly connected to the right end of the second bevel gear 10, the rotating shaft 11 is rotatably connected to the right side of the inner wall of the base 1, the threaded rod 6 is threadedly connected to the inner wall of the rotating shaft 11, a telescopic rod 12 is fixedly connected to the left end of the threaded rod 6, the left end of the telescopic rod 12 is rotatably connected to the inner wall of the base 1, and a first knob 19 is fixedly connected to the front end of the rotating shaft 8.

[0026] Specifically, when multiple cable protection devices need to be spliced, first align the connecting hole 7 at the left end of the second cable protection device base 1 with the threaded rod 6 at the right end of the first cable protection device base 1, and then rotate the first knob 19 to make the first knob 19 drive the rotating shaft 8 to rotate, thereby driving the first bevel gear 9 to rotate, and then making the second bevel gear 10 rotate. The rotation of the second bevel gear 10 drives the rotating shaft 11 to rotate, and cooperates with the telescopic rod 12 at the left end to make the threaded rod 6 on the inner wall of the rotating shaft 11 move to the right, so that it is threadedly connected with the connecting hole 7 at the left end of the second cable protection device base 1, and the telescopic rod 12 at the left end of the threaded rod 6 can effectively prevent the first knob 19 from being excessively rotated so that the threaded rod 6 completely leaves the inner wall of the base 1. Finally, it can be spliced ​​into the required length according to the on-site cable length conditions to meet the wiring requirements of cables of different lengths, and it can be split into multiple protection devices for easy transportation.

[0027] A first protective cover 2 is fixedly connected to the top of the base 1, and a second protective cover 3 is rotatably connected to the top of the first protective cover 2. First fixed blocks 5 are fixedly connected to the left and right sides of the front end of the first protective cover 2, and second fixed blocks 4 are fixedly connected to the left and right sides of the front end of the second protective cover 3. Blocks 15 are fixedly connected to the bottom and middle of the left and right connecting rods 14 respectively. The shapes of the upper and lower block blocks 15 match the inner wall grooves of the first fixed block 5 and the second fixed block 4. A spring 17 is fixedly connected to the front end of the inner wall of the second fixed block 4, and an extrusion plate 16 is fixedly connected to the front end of the spring 17. Second knobs 13 are fixedly connected to the tops of the left and right connecting rods 14, and identification lines 18 are engraved on the tops of the second knobs 13 on the left and right sides and the second fixed block 4.

[0028] Specifically, when protecting the cable, first put the cable into the first protective cover 2 and the second protective cover 3, then close them, and then press the second knob 13 downwards. When it reaches the bottom, turn the second knob 13. The second knob 13 will first drive the two blocks 15 on the connecting rod 14 to move downwards, and then make the upper and lower blocks 15 rotate to the grooves on the inner walls of the first fixing block 5 and the second fixing block 4 respectively. At this time, the spring 17 will rebound the extrusion plate 16 to squeeze the block 15 to prevent the block 15 from loosening during use. The second fixing block 4 and the second knob 13 The marking line 18 can facilitate workers to confirm whether the current card block 15 is in the card slot position. When the marking lines 18 at the two places are in a vertical position, it means that the card block 15 is in the card slot position, which ultimately closes the first fixing block 5 and the second fixing block 4, thereby closing the first protective cover 2 and the second protective cover 3. When opening, it is only necessary to rotate the second knob 13 in the opposite direction and then lift it up to make the card block 15 leave the card slot, so that the first fixing block 5 and the second fixing block 4 can be separated. Finally, the simple operation method makes it easier for users to understand and master, reducing the learning cost and difficulty of use.

[0029] Working principle: When multiple cable protection devices need to be spliced, first align the connection hole 7 at the left end of the second cable protection device base 1 with the threaded rod 6 at the right end of the first cable protection device base 1, and then turn the first knob 19. The first knob 19 drives the rotating shaft 8 to rotate, thereby driving the first bevel gear 9 to rotate, and then the second bevel gear 10 rotates. The rotation of the second bevel gear 10 drives the rotating shaft 11 to rotate, and cooperates with the telescopic rod 12 at the left end to make the threaded rod 6 on the inner wall of the rotating shaft 11 move to the right, so that it is threadedly connected with the connection hole 7 at the left end of the second cable protection device base 1. Finally, it can be spliced ​​into the required length according to the on-site cable length conditions to meet the wiring requirements of cables of different lengths. When the cable needs to be protected, first put the cable into the first protective cover 2 and the second protective cover 3, then close them, and then press the second knob 13 downward. When it reaches the bottom, turn the second knob 13 again. The second knob 13 will first drive the two blocks 15 on the connecting rod 14 to move downward, and then make the upper and lower blocks 15 rotate to the grooves on the inner walls of the first fixed block 5 and the second fixed block 4 respectively. At this time, the spring 17 will rebound the extrusion plate 16 to squeeze the block 15 to prevent the block 15 from loosening during use, and finally close the first fixed block 5 and the second fixed block 4, thereby closing the first protective cover 2 and the second protective cover 3. The simple operation method makes it easier for users to understand and master.

[0030] 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.
