Description

Technical Field

[0001] This utility model relates to the field of cable traction technology, and in particular to a cable traction device for cable construction. Background Technology

[0002] Cable pulling is a crucial step in cable installation. Traditional cable pulling devices have revealed numerous problems in practical applications.

[0003] First, traditional devices often lack effective adaptation mechanisms for cables of different specifications and sizes. The guiding and limiting structures of many devices are fixed and difficult to adjust flexibly to accommodate diverse cable outer diameters. This can lead to situations where cables are not securely fixed, shake during the pulling process, or even fall off when pulling cables of different specifications, seriously affecting construction quality and progress.

[0004] Furthermore, traditional devices lack flexibility in controlling the cable exit position. Construction site environments are complex and varied, with different requirements for cable exit positions. Traditional traction devices typically struggle to precisely adjust the exit position according to actual construction needs, limiting their application in complex construction scenarios. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this utility model provides a traction device for cable construction.

[0006] The technical solution of this utility model is as follows: a traction device for cable construction, comprising a base, a first motor, a winding wheel, a fixed plate, a guide frame, a sliding seat, a connecting seat, a guide wheel, a fixed frame, a lower roller, a moving component, and an adjusting component. The first motor is installed on the right rear side of the top of the base, and the winding wheel is connected to the output shaft of the first motor. The left end of the winding wheel is threadedly connected to the fixed plate. The guide frame is connected to the front side of the top of the base, and the sliding seat is slidably connected inside the guide frame. The top of the sliding seat is connected to the connecting seat, and four guide wheels are rectangularly arranged on the connecting seat. The guide wheels are composed of a support rod and a wheel rod assembly. The support rod and the connecting seat are slidably connected, while the wheel rod and the support rod are rotatably connected. Fixed frames are connected to the two side walls of the sliding seat, and lower rollers are symmetrically rotatably connected between the two fixed frames. The moving component is provided on the guide frame, and the adjusting component is provided at the bottom of the connecting seat.

[0007] In one embodiment, the moving component includes a second motor and a first screw. The second motor is connected to the left side of the guide frame, the first screw is rotatably connected inside the guide frame, the sliding seat is threadedly connected to the first screw, and the output shaft of the second motor is connected to the first screw.

[0008] In one embodiment, the adjustment assembly includes a third motor, a rotating frame, and a sliding frame. The third motor is installed in the middle of the bottom of the connecting seat, and the rotating frame is connected to the output shaft of the third motor.

Detailed Implementation

[0020] Example: A cable traction device for cable construction, such as... Figures 1-3 As shown, the device includes a base 1, casters 2, a first motor 3, a winding wheel 4, a fixed disc 5, a guide frame 6, a sliding seat 9, a connecting seat 10, guide wheels 14, a fixed frame 15, lower rollers 19, a moving assembly, and an adjusting assembly. The base 1 has self-locking casters 2 installed at each of its four bottom corners, allowing construction personnel to easily move the device across different terrains. The first motor 3 is bolted to the top right rear side of the base 1. A winding wheel 4 is connected to the output shaft of the first motor 3, and a fixed disc 5 is threaded to the left end of the winding wheel 4. This structure is used for winding and releasing the cable, providing power for cable traction. The front top of the base 1 is bolted... A guide frame 6 is connected to the cable, and a sliding seat 9 is slidably connected inside the guide frame 6. A connecting seat 10 is connected to the top of the sliding seat 9. Four guide wheels 14 are rectangularly arranged on the connecting seat 10. The guide wheels 14 are composed of a support rod and a wheel rod assembly. The support rod and the connecting seat 10 are slidably connected, while the wheel rod and the support rod are rotatably connected. The function of the guide wheels 14 is to limit the cable and ensure the stability of the cable position during the traction process. Fixed frames 15 are connected to the left and right side walls of the sliding seat 9, and lower rollers 19 are symmetrically rotatably connected between the two fixed frames 15 to assist the movement of the cable. A moving component is provided on the guide frame 6, and an adjusting component is provided at the bottom of the connecting seat 10.

[0021] like Figures 1-2 As shown, the moving component includes a second motor 7 and a first screw 8. The second motor 7 is bolted to the left side of the guide frame 6, and the first screw 8 is rotatably connected inside the guide frame 6. The sliding seat 9 is threadedly connected to the first screw 8, and the output shaft of the second motor 7 is connected to the first screw 8.

[0022] like Figure 3 As shown, the adjustment assembly includes a third motor 11, a rotating frame 12, and a sliding frame 13. The third motor 11 is bolted to the bottom center of the connecting seat 10. The rotating frame 12 is connected to the output shaft of the third motor 11. A sliding frame 13 is connected between the bottom of the support rods of each pair of symmetrical guide wheels 14. The bottom of the sliding frame 13 has a sliding groove, which is slidably connected to the rotating frame 12 to adjust the distance between the guide wheels 14 to accommodate cables of different sizes.

[0023] During cable installation, firstly, the reel containing the cable is fitted onto the winding wheel 4. During this process, the fixing disc 5 needs to be removed from the winding wheel 4. After the reel is in place, the fixing disc 5 is re-threaded onto the left end of the winding wheel 4 to secure the reel. Next, one end of the cable is pulled, allowing it to pass through the gap between the two guide wheels 14, with the bottom surface of the cable directly contacting the lower roller 19. The third motor 11 is then started, and its output shaft rotates, driving the rotating frame 12 to rotate. Because the rotating frame 12 and the sliding frame 13 have a sliding fit at the bottom, the rotation of the rotating frame 12 can cause the two sliding frames 13 to move closer or further apart, thereby causing the guide wheels 14 to move synchronously, achieving clamping and limiting of the cable. After the limit is reached, the third motor 11 is turned off. This adjustment method allows the guide wheel 14 to be used with cables of different sizes and specifications. After completing the above steps, if it is necessary to pull out the cable for use, the first motor 3 can be started. The output shaft of the first motor 3 rotates, driving the winding wheel 4 and the fixed disc 5 connected to it to rotate, thereby driving the drum to rotate and realizing the cable unwinding operation. When pulling the cable for use, the movement of the cable will generate friction with the guide wheel 14 and the lower roller 19. This friction can drive the wheel rod on the guide wheel 14 and the lower roller 19 to rotate, thereby assisting the movement of the cable and making the cable traction more effortless. At the same time, the left and right positions of the sliding seat 9 can be adjusted according to the actual cable exit position requirements. When the second motor 7 is started, the output shaft of the second motor 7 rotates, which drives the first screw 8 to rotate. Since the sliding seat 9 and the first screw 8 are threadedly connected, the rotation of the first screw 8 can drive the sliding seat 9 to adjust its position in the left and right directions along the guide frame 6, thereby driving the guide wheel 14 to move and adjust synchronously, so as to achieve precise control of the cable exit position and meet the actual needs of different construction scenarios. When winding the cable, it can also be achieved by the first motor 3 and the winding wheel 4 working together.

[0024] like Figure 4 As shown, it also includes a fourth motor 16, a second screw 17, a lifting frame 18, and an upper roller 20. The fourth motor 16 is bolted to the fixed frame 15. The second screw 17 is welded to the output shaft of the fourth motor 16. The lifting frame 18 is threadedly connected to the second screw 17. The lifting frame 18 is slidably connected to the fixed frame 15. The upper roller 20 is symmetrically rotated between the two lifting frames 18. The surface of the upper roller 20 is covered with an elastic material. On the one hand, it can buffer the pressure on the cable and avoid hard squeezing to damage the cable sheath. On the other hand, the elastic material can better fit the cable surface, further enhance the friction, and play a certain role in shock absorption and reset when the cable shakes slightly, maintaining the stability of cable traction.

[0025] After the cable passes between the two guide wheels 14 and is stopped, the bottom surface of the cable directly contacts the lower roller 19. At this time, the fourth motor 16 is started, and its output shaft rotates, driving the second screw 17 to rotate, which in turn moves the lifting frame 18 and the upper roller 20 downward. The upper roller 20 applies a vertical downward pressure to the cable, which, together with the lower roller 19, forms an upper and lower clamping and limiting structure for the cable, effectively preventing the cable from detaching from the device due to external interference during traction. The upper roller 20 and the lower roller 19 also rotate due to the movement of the cable. When it is necessary to release the cable's constraint, the fourth motor 16 is controlled to rotate in the opposite direction, driving the second screw 17 to rotate in reverse, which in turn moves the lifting frame 18 and the upper roller 20 upward to release the cable's constraint.
