[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a cable laying guide device, comprising a frame 1, a first connecting plate 2 fixedly connected to the inner bottom of the frame 1, a second connecting plate 3 fixedly connected to the inner upper end of the frame 1, a telescopic frame 4 movable vertically on the inner side of the frame 1, a base plate 5 fixedly installed at the bottom of the telescopic frame 4, a first fixing plate 6 fixedly connected to the front upper end of the frame 1, a first guide roller 7 rotatably connected to the middle of the first fixing plate 6, an adjusting roller 8 installed on the inner upper end of the frame 1, a second fixing plate 9 fixedly connected to the outer lower end of the telescopic frame 4, a second guide roller 10 rotatably connected to the middle of the second fixing plate 9, and a second guide roller 10 installed on the front lower end of the frame 1. An opening 19 is provided for the second fixed plate 9 to move up and down. A U-shaped plate 11 is fixedly connected to the front side of the base plate 5. An auxiliary roller 12 is rotatably connected to the inner side of the U-shaped plate 11. Pins 13 are fixedly connected to the upper sides of both the left and right ends of the base plate 5. The outer wall of the pin 13 fits tightly against the lower inner wall of the telescopic frame 4. A fastener 14 for fixing the pin 13 is threadedly connected to the lower outer side of the telescopic frame 4. A pin 15 for increasing friction is fixedly connected to the lower end of the base plate 5. A fixing hole 16 is provided on the upper rear side of the telescopic frame 4. An adjustment hole 17 is provided on the rear side of the frame 1. A fixing pin 18 is provided inside the adjustment hole 17. The end of the fixing pin 18 is inserted into the inside of the fixing hole 16.
[0024] Based on the actual depth of the cable well, the telescopic frame 4 is pulled out to extend downwards along the inner guide rail of the frame 1. When the telescopic frame 4 extends to the target position, the fixing pin 18 is inserted to achieve mechanical interlocking by matching the corresponding holes of the fixing hole 16 and the adjusting hole 17. The cable passes sequentially around the upper surface of the adjusting roller 8, the lower surface of the first guide roller 7, the rear side of the second guide roller 10, and the upper surface of the auxiliary roller 12, forming an "S" shaped wrapping path. This multi-roller guide design transforms traditional sliding friction into rolling friction, reducing traction resistance. The U-shaped plate 11 and the auxiliary roller 12 form a cantilever buffer structure to avoid friction with the bottom of the well and also to avoid friction with the cable well, which would cause wear on the outer wall of the cable and affect its service life. When not in use, the telescopic frame 4 can be stored inside the frame 1, thereby reducing the size of the device and facilitating transportation and storage.
[0025] Reference Figures 1-3 An adjusting roller 8 is provided on the inner side of the upper end of the frame 1. A top block 21 is fixedly connected to the top of the frame 1. Limiting rods 22 are fixedly connected to both the front and rear ends of the top block 21. The lower end of the limiting rod 22 is fixedly connected to the inside of the second connecting plate 3. A lifting block 23 that slides up and down is provided on the outside of the limiting rod 22. The left and right ends of the adjusting roller 8 are respectively rotatably connected to the middle of the lifting block 23. A lead screw 24 is threadedly connected to the middle of the lifting block 23 at the right end of the frame 1. The upper end of the lead screw 24 is rotatably connected to the middle of the top block 21. The lower end of the lead screw 24 is rotatably connected to the inside of the second connecting plate 3. A rotating handle 25 is fixedly connected to the top of the lead screw 24. An adjusting port 20 for the up and down movement of the adjusting roller 8 is provided on the inner side of the upper end of the frame 1. A rotating plate 26 is rotatably connected to the upper rear end of the frame 1. A baffle 27 for limiting the rotating plate 26 is fixedly connected to the upper rear side of the frame 1 above the rotating plate 26.
[0026] The rotating handle 25 drives the lead screw 24 to drive the lifting block 23 to move precisely along the limit rod 22, thereby realizing the height adjustment of the adjusting roller 8. This allows for adjustment according to the cable diameter. When the cable diameter is large, the cable bending arc is small, which can increase the height difference between the adjusting roller 8 and the first guide roller 7, allowing the adjusting roller 8 to contact the cable and provide support. The rotating plate 26 on the rear side of the frame 1 is unfolded to a horizontal state, so that it overlaps the edge of the cable well opening. Ground nails are used to penetrate the fixing holes 16 of the rotating plate 26 to anchor the device to the ground at the well opening. The baffle 27 restricts the excessive rotation of the rotating plate 26. The conical pin 15 at the bottom of the base plate 5 is embedded into the soil layer at the bottom of the well under the action of the device's own weight, improving the stability of the device.
[0027] Working principle: During cable laying, the frame 1 and telescopic frame 4 are adjusted according to the depth of the cable well, so that the telescopic frame 4 extends downward inside the frame 1. After adjustment, the fixing pin 18 is inserted into the adjustment hole 17 corresponding to the fixing hole 16, thereby fixing the frame 1 and telescopic frame 4. The device is placed in the cable well, and the rotating plate 26 is unfolded so that it is perpendicular to the frame 1 and contacts the edge of the cable well opening. The rotating plate 26 is fixed in the soil at the edge of the cable well by fixing nails, while the pin 15 is inserted into the soil at the bottom of the cable well, thereby improving the stability of the device; the laying... The cable is designed to pass over the adjusting roller 8 and the first guide roller 7, then around the back of the second guide roller 10, and finally pass over the auxiliary roller 12. During the pulling process, the rotation of the first guide roller 7, the adjusting roller 8, the second guide roller 10, and the auxiliary roller 12 can reduce the friction of the cable during the pulling process. The rotating handle 25 drives the lead screw 24 to rotate, and the rotating lead screw 24 drives the lifting block 23 to move up and down, thereby driving the adjusting roller 8 to move up and down, thereby adjusting the height difference between the adjusting roller 8 and the first guide roller 7, so as to adjust according to the diameter of the cable.
[0028] 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.
