In the vertical direction, the first transmission wheel 6 is located below the second transmission wheel 7. A space for accommodating the cable 5 is formed between the two first transmission wheels 6 and the two second transmission wheels 7. The cable 5 is arranged between the two first transmission wheels 6 or the two second transmission wheels 7. A first support column 9 is rotatably connected below the first transmission wheel 6, and a second support column 10 is rotatably connected below the second transmission wheel 7. A folding rod 8 is arranged at the lower end of the first support column 9 and the second support column 10 and both are connected to the folding rod 8. A reduction motor 17 is arranged below the folding rod 8, and the folding rod 8 is fixedly connected to the output shaft of the reduction motor 17. The base of the reduction motor 17 is connected to the bridge frame 3 by bolts.

[0023] See also Figure 2 The folding rod 8 includes a middle rod 83, two first folding rods 81 and two second folding rods 82. Both ends of the middle rod 83 are fixedly connected to the ends of the two first folding rods 81. The ends of the first folding rods 81 are fixedly connected to the second folding rods 82. The two second folding rods 82 are collinear. The straight line where the second folding rods 82 are located is perpendicular to the straight line where the middle rod 83 is located and passes through the midpoint of the middle rod 83.

The middle of the middle rod 83 is fixedly connected to the output shaft of the reduction motor 17.

[0024] See also Figure 2 The first support column 9 and the second support column 10 are hollow inside, the length of the first support column 9 is smaller than that of the second support column 10, the first transmission wheel 6 is arranged at the upper end of the first support column 9, the first support column 9 is rotatably connected to the first transmission wheel 6, the lower end of the first support column 9 is fixedly connected to the first folding rod 81, a first micro motor (not shown) is installed inside the first support column 9, the output shaft of the first micro motor extends out of the first support column 9 and is fixedly connected to the first transmission wheel 6. When the first micro motor is working, the output shaft drives the first transmission wheel 6 to rotate around the first support column 9, the two first transmission wheels 6 rotate in opposite directions, and can drive the cable 5 placed between the two first transmission wheels 6 to move.

[0025] The second transmission wheel 7 is arranged at the upper end of the second support column 10, and the second support column 10 is rotatably connected with the second transmission wheel 7. A second micro motor (not shown) is installed inside the second support column 10, and the output shaft of the second micro motor extends out of the second support column 10 and is fixedly connected with the second transmission wheel 7. A collar 11 is fixed at the lower end of the second support column 10, and the collar 11 is sleeved on the second folding rod 82, and the collar 11 can slide on the second folding rod 82. When the second micro motor is working, the output shaft drives the second transmission wheel 7 to rotate around the second support column 10, and the two second transmission wheels 7 rotate in opposite directions, and can drive the cable 5 placed between the two second transmission wheels 7 to move.

[0026] See also Figure 3 The inner circumference of the collar 11 is provided with a protrusion, and the position of the second folding rod 82 corresponding to the protrusion is provided with a strip groove 12, the protrusion is embedded in the strip groove 12, and a spring 13 is arranged in the strip groove 12, one end of the spring 13 is connected to the inner wall of the strip groove 12 close to the end of the second folding rod 82, and the other end is connected to the protrusion. When the spring 13 is naturally extended, the second support column 10 is located on the side of the strip groove 12 away from the end of the second folding rod 82. When the diameter of the cable 5 is too large, the cable 5 is located between the second transmission wheels 7, and the cable 5 squeezes the second transmission wheel 7 to move to both sides, and the second transmission wheel 7 drives the collar 11 to move along the second folding rod 82 to both sides. At this time, the spring 13 is compressed, and the elastic force of the spring 13 acts on the collar 11, and the collar 11 allows the second transmission wheel 7 to be close to the cable 5. In this case, the reduction motor 17 is not required, and the folding rod 8 does not need to rotate.

[0027] See also Figure 2 The first transmission wheel 6 is an hourglass shape with a thin top and a thick bottom. The longitudinal section of the first transmission wheel 6 is composed of two different isosceles trapezoids. The width of the narrowest part of the middle of the first transmission wheel 6 is smaller than the width of the upper end, and the width of the upper end is smaller than the width of the lower end. The first micro motor controls the self-rotation. When the diameter of the cable 5 is small, the cable 5 is located between the first transmission wheels 6. Since the first transmission wheels 6 are an hourglass shape with a thin top and a thick bottom, the cable 5 with a small diameter is stuck between the two first transmission wheels 6 and will not fall.

[0028] If the cable is too thin, the first transmission wheel 6 cannot clamp the cable 5. At this time, the reduction motor 17 is turned on to rotate the folding rod 8 clockwise at a small angle, and the first transmission wheel 6 rotates with the folding rod 8, close to the cable 5, without bending the cable 5 and affecting the transportation of the cable 5. After clamping the cable 5 with a smaller diameter, the first micro motor works, and the first transmission wheel 6 rotates and drives the cable 5 to move forward in the bridge 3.

[0029] See also Figure 2 The second transmission wheel 7 is a standard hourglass type, and the longitudinal section of the second transmission wheel 7 is composed of two identical isosceles trapezoids. The second transmission wheel 7 is wide at both ends and narrow in the middle. The second micro motor controls the rotation. When the diameter of the cable 5 is large, the cable 5 is located between the second transmission wheels 7. When the diameter of the cable 5 is too large, the distance between the two second transmission wheels 7 can be opened first, and then under the action of the spring 13, the two second transmission wheels 7 clamp the cable 5, the reduction motor 17 starts and drives the folding rod 8 to rotate clockwise, and the second transmission wheel 7 moves with the folding rod 8 to be close to the cable 5, clamping the cable 5 with a larger diameter, and then the second micro motor works, the second transmission wheel 7 rotates and drives the cable 5 to move forward in the bridge 3.

[0030] The outer surfaces of the first transmission wheel 6 and the second transmission wheel 7 are both made of high-performance anti-skid materials. The mechanical energy generated by the rotation of the transmission wheels is transmitted to the cable 5, so that the cable 5 can be automatically advanced.

[0031] The guide wheel 14 is arranged at the turning point of the bridge frame 3. The guide wheel 14 is a fixed pulley, which assists the cable 5 in turning and prevents the cable 5 from scraping the bridge frame 3 and causing damage.

[0032] The traction rope 2 is a high-toughness rope, which is used to connect the end winch, provide auxiliary power generated by the winch and guide the laying of the cable 5.

[0033] The winch 1 guides the cable 5 in a forward direction through the traction rope 2 and provides a certain amount of auxiliary power.

[0034] Working process: first, install the transmission wheel group 4 on the bridge 3 by bolts, and multiple transmission wheel groups 4 are arranged along the bridge 3 at a preset distance. A guide wheel 14 is arranged at the turning point of the bridge 3. Then the construction personnel extend the cable 5 along the bridge 3 to the winch 1, and during the extension of the cable 5, the cable 5 is passed through the transmission wheel group 4. The transmission wheel group 4 is adjusted to fit the cable 5. The winch 1 is connected to the cable 5 through the traction rope 2. When laying the cable 5, the winch 1 and the transmission wheel group 4 are started. At this time, the winch 1 and the transmission wheel group 4 drive the cable 5 through the bridge 3 along the preset trajectory, thereby completing the laying of the cable 5.
