An upper movable frame is located above the lower movable frame, and a second upper roller is mounted on the bearing on the inner wall of the upper movable frame.

[0008] The above technical solution facilitates the adjustment of the traction angle to meet diverse traction needs.

[0009] As a preferred embodiment of this utility model, a fixed frame is fixedly installed in the middle of the top surface of the base, and an electric push rod is fixedly installed on the top surface of the fixed frame. The output shaft of the electric push rod movably passes through the top of the fixed frame, and a movable plate is fixedly installed at the output end of the electric push rod. The left bottom end of the movable plate is fixedly connected to the bottom surface of the upper bracket, and an installation shaft is fixedly installed at the right bottom end of the movable plate. The bottom end of the installation shaft is connected to the center bearing on the top surface of the upper movable frame.

[0010] By adopting the above technical solution, when the moving plate is driven by the electric push rod, the upper support and the upper movable frame are moved, so that the first upper roller and the second upper roller move synchronously to press the cable.

[0011] As a preferred embodiment of this utility model, a threaded rod is mounted on the rear inner wall of the base, and the threaded rod bearing penetrates the front side wall of the base. A slider is sleeved on the outer side of the threaded rod, and the top surface of the slider is slidably connected to the inner top surface of the base.

[0013] As a preferred embodiment of this utility model, a rotating rod is provided through the top longitudinal bearing of the base, and the top end of the rotating rod is fixedly connected to the center of the bottom surface of the lower movable frame. The bottom end of the rotating rod is connected to the inner bottom surface bearing of the base, and a gear is fixedly installed on the surface of the rotating rod, and the gear meshes with the rack.

[0014] The above technical solution facilitates the rotation of the rotating rod and the lower movable frame via gears when the rack moves.

[0015] As a preferred embodiment of this utility model, a handwheel is provided on the front side of the base, and the handwheel is coaxially fixedly installed on the front end of the threaded rod.

[0016] The above technical solution facilitates the operation of the threaded rod via a handwheel, improving operational flexibility.

[0017] As a preferred embodiment of this utility model, the lower movable frame has vertical rods fixedly installed on its inner bottom surface, and four vertical rods are arranged symmetrically in pairs, and the vertical rods are movably installed through the top of the upper movable frame.

[0020] The above technical solution facilitates the rotation of the second lower roller by driving it with a motor, thereby increasing the power for line traction.

[0022] 1. With the flexible extension and retraction of the electric push rod, the distance between the first upper roller and the first lower roller, and between the second upper roller and the second lower roller can be precisely adjusted. When dealing with communication cables of different thicknesses, the distance can be easily adjusted to ensure that the cable fits tightly against the roller, ensuring a stable traction process. This greatly improves the device's versatility for various types of cables, avoids compatibility problems caused by differences in cable thickness, and effectively reduces the cost and time consumption of frequently changing equipment during construction.

[0023] 2. By turning the handwheel, the threaded rod can be driven to rotate, which in turn moves the slider. Through the meshing transmission of the rack and pinion, the angle of the lower movable frame and the corresponding roller can be adjusted. This design allows the device to flexibly adjust the traction angle according to actual needs when facing construction scenarios with complex bends, ensuring that the cable can be laid smoothly. It overcomes the limitations of traditional traction devices in special construction environments, significantly enhances the adaptability of the device in complex construction environments, reduces construction obstacles, and improves construction efficiency.

[0024] 3. The motor drives the second lower roller to rotate, providing continuous and stable power for cable traction, ensuring efficient and stable cable traction work, reducing traction difficulty, and improving the quality of communication cable construction. Attached Figure Description

[0032] Example 1

[0033] Please see Figure 1 - Figure 4 The present invention provides a traction device for communication cable construction, comprising a base 1 and universal wheels 2 with brakes located at the four corners of the bottom surface of the base 1. A lower support 3 is fixedly installed on the left end of the top surface of the base 1, and a first lower roller 4 is installed on the bearing of the inner wall surface of the lower support 3. An upper support 5 is provided above the lower support 3, and a first upper roller 6 is installed on the bearing of the inner wall surface of the lower support 3. A lower movable frame 7 is installed on the bearing of the right end of the top surface of the base 1, and a second lower roller 8 is installed on the bearing of the inner wall surface of the lower movable frame 7. An upper movable frame 9 is provided above the lower movable frame 7, and a second upper roller 10 is installed on the bearing of the inner wall surface of the upper movable frame 9. A vertical rod 15 is fixedly installed on the inner bottom surface of the lower movable frame 7, and four vertical rods 15 are arranged symmetrically in pairs, and the vertical rods 15 are movably inserted through the top of the upper movable frame 9.

[0034] A fixed frame 11 is fixedly installed in the middle of the top surface of the base 1, and an electric push rod 12 is fixedly installed on the top surface of the fixed frame 11. The output shaft of the electric push rod 12 moves through the top of the fixed frame 11, and a movable plate 13 is fixedly installed at the output end of the electric push rod 12. The left bottom end of the movable plate 13 is fixedly connected to the bottom surface of the upper bracket 5, and a mounting shaft 14 is fixedly installed at the right bottom end of the movable plate 13. The bottom end of the mounting shaft 14 is connected to the center bearing on the top surface of the upper movable frame 9.

[0035] A threaded rod 20 is mounted on the bearing of the inner rear wall of the base 1, and the bearing of the threaded rod 20 passes through the front side wall of the base 1. A slider 19 is sleeved on the outer side of the threaded rod 20, and the top surface of the slider 19 is slidably connected to the inner top surface of the base 1. The threaded rod 20 is threadedly connected to the slider 19, and a rack 18 is fixedly mounted on the bottom surface of the slider 19.

[0036] A rotating rod 16 is provided through the top longitudinal bearing of the base 1, and the top end of the rotating rod 16 is fixedly connected to the center of the bottom surface of the lower movable frame 7. The bottom end of the rotating rod 16 is connected to the inner bottom surface bearing of the base 1, and a gear 17 is fixedly installed on the surface of the rotating rod 16. The gear 17 is meshed with the rack 18. A handwheel 21 is provided on the front side of the base 1, and the handwheel 21 is coaxially fixedly installed on the front end of the threaded rod 20.

[0037] Working principle: When in use, place the cable on top of the first lower roller 4 and the second lower roller 8, start the electric push rod 12 to push the moving plate 13 down, the moving plate 13 drives the upper bracket 5 and the upper movable frame 9 connected by the mounting shaft 14 to descend accordingly, thereby pressing the cable tight and ensuring the cable can be pulled.

[0038] When the traction angle needs to be adjusted, the handwheel 21 is turned to drive the threaded rod 20 to rotate. Since the threaded rod 20 is threadedly connected to the slider 19, the slider 19 will move left and right along the threaded rod 20. The rack 18 fixed on the bottom surface of the slider 19 moves accordingly. The rack 18 meshes with the gear 17 on the surface of the rotating rod 16, thereby driving the rotating rod 16 to rotate. When the rotating rod 16 rotates, it drives the lower movable frame 7 to rotate. Through the placement of the vertical rod 15, the upper movable frame 9 rotates synchronously, thereby realizing the angle adjustment of the second lower roller 8 and the second upper roller 10 to adapt to construction scenarios with special curvature.

The shaft end of the motor 22 is fixedly connected to the shaft end of the second lower roller 8. With the above design, the output shaft of the motor 22 can drive the second lower roller 8 fixedly connected to it to rotate. When the second lower roller 8 rotates, it generates friction with the cable, driving the cable to move forward, realizing the cable traction operation and reducing the difficulty of traction.
