Detailed Implementation

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0032] Reference Figures 1-6 As shown, a cable installation traction device includes: a fixed frame 103 fixedly mounted on a base 100; a mounting plate 104 hinged to the fixed frame 103; multiple sets of guide rollers 105 rotatably mounted on the mounting plate 104 for guiding cables; multiple sets of clamping mechanisms 200 for clamping and fixing cables of different sizes on the mounting plate 104; guide members hinged to the side of the mounting plate 104 for guiding cables of different installation heights and angles; and a limiting mechanism 300 fixed on the mounting plate 104 beside the guide members for limiting the movement of cables of different sizes during installation.

[0033] In use, when performing cable installation and traction operations, the base 100 of the traction device is first fixedly installed in a suitable position to provide stable support for the entire device. Subsequently, according to the required height and angle for cable installation, the mounting plate 104 is adjusted through the hinge structure. The guide components on the side of the mounting plate 104 are then adjusted to the appropriate installation height and angle, thus determining the initial guiding direction of the cable. The cable passes through the guide rollers 105, and multiple sets of spaced guide rollers 105 provide initial guidance for the cable, placing it in the center position of the device. Next, based on the specific dimensions of the cable, the clamping mechanism 200 is activated to adaptively clamp and fix the cable, ensuring that the cable will not shift or slip during traction. During traction, the limiting mechanism 300 plays a role. Located beside the guide, it limits the position of cables of different sizes through a set limiting structure, preventing the cable from leaving the predetermined guide path due to external force during traction, further ensuring the stability and accuracy of cable traction. By setting adjustable clamping mechanism 200 and limiting mechanism 300, it can adapt to the installation and traction needs of cables of different sizes. Compared with traditional devices that only adapt to a single fixed diameter cable, it greatly improves the versatility of the device and reduces the need for frequent replacement or adjustment of the device due to changes in cable specifications.

[0034] Reference Figures 3-6 As shown, the limiting mechanism 300 includes: a fixed frame 301, a spring 303, and an upper pressure roller 304; wherein,

[0035] A fixing frame 301 is fixedly provided on the mounting plate 104. A vertical sliding groove 302 is provided on the inner side wall of the fixing frame 301. A spring 303 is fixedly provided in the sliding groove 302. An upper pressure roller 304 is fixedly connected to the top of the spring 303. A fixing roller 305 parallel to the upper pressure roller 304 is rotatably provided in the fixing frame 301.

[0036] In the above scheme, after the cable passes through the guide roller 105 and is initially fixed by the clamping mechanism 200, the cable will enter the working area of ​​the limiting mechanism 300. At this time, the cable is located between the upper pressure roller 304 and the fixed roller 305. Since the spring 303 is set in the groove 302 on the inner side wall of the fixed frame 301, the spring 303 is in a natural elastic state. Under the action of the spring 303, the upper pressure roller 304 will apply a certain pressure downward, tightly clamping the cable between itself and the fixed roller 305. During the traction process, if the cable is subjected to external force and has an upward or downward tendency, the upper pressure roller 304 will slide up and down in the groove 302 with the displacement of the cable. When the cable deviates upward, the upper pressure roller 304 moves upward against the elastic force of the spring 303, and the spring 303 is compressed, providing a reverse force to press the cable back to its original position; when the cable deviates downward, the elastic force of the spring 303 pushes the upper pressure roller 304 downward, pushing the cable back to its original position, thereby ensuring that the cable is always on the predetermined guide path and continuously providing a stable limiting effect for cable traction.

[0037] Reference Figures 2-3 As shown, each clamping mechanism 200 includes: a bidirectional screw 203, a threaded block 204, and a clamping roller 205; wherein,

[0038] The mounting plate 104 has a horizontal guide groove 202. A bidirectional screw 203 is rotatably installed in the guide groove 202. The bidirectional screw 203 has two sections of threads with opposite directions. Each section of thread is threaded with a threaded block 204. Each threaded block 204 is equipped with a clamping roller 205. A rotary motor 201 with a horizontally set output shaft and a fixed top end to the bidirectional screw 203 is fixedly installed on the mounting plate 104. Adjacent sets of bidirectional screws 203 are connected by a transmission belt 206.

[0039] During cable clamping and fixing, the rotary motor 201 is first started, and its output shaft drives the bidirectional screw 203 to rotate. Since the bidirectional screw 203 has two sections of threads with opposite directions, when it rotates, the two threaded blocks 204 fitted onto it move towards or away from each other along the screw 203 under the limiting action of the guide groove 202. When cable clamping is required, the rotary motor 201 rotates forward, and the two threaded blocks 204 drive the clamping rollers 205 to move towards each other, gradually approaching the cable. As the threaded blocks 204 move, the clamping rollers 205 squeeze the cable from both sides until it is firmly clamped. During clamping, because adjacent sets of bidirectional screws 203 are connected by a transmission belt 206, multiple clamping mechanisms 200 can operate synchronously, ensuring uniform and stable clamping of the cable.

[0040] Reference Figures 1-6As shown, the guide includes a connecting rod 106 and a fixing sleeve 107; the connecting rod 106 is hinged on the mounting plate 104, the top surface of the connecting rod 106 is provided with a through hole 108 for the cable to pass through, and the fixing sleeve 107 is fixedly provided on the connecting rod 106 and coaxially arranged with the through hole 108.

[0041] During cable installation and traction, the cable is first passed through the fixing sleeve 107 and the through hole 108 to position it on the guide. Since the connecting rod 106 is hinged to the mounting plate 104, when adjusting the cable's installation height and angle, force can be applied to the connecting rod 106 manually or via external equipment, causing it to rotate around the hinge point. During rotation, the fixing sleeve 107 and the through hole 108 change position and angle, thus adjusting the cable's guiding direction until the desired installation height and angle are achieved. After adjustment, the cable is stably guided along the path defined by the fixing sleeve 107 and the through hole 108 during traction, preventing arbitrary deviation and ensuring the cable is installed along the predetermined trajectory.

[0042] Reference Figures 5-6 As shown, the mounting plate 104 is provided with a steering mechanism 400 that drives the connecting rod 106 to swing around the hinge point.

[0043] In the above scheme, the steering mechanism 400 enables automated and precise control of the guide components. Compared to manually adjusting the guide components, the steering mechanism 400 can quickly and accurately adjust the connecting rod 106 to the required angle and position, greatly improving the efficiency of cable installation. Simultaneously, by precisely controlling the swing of the connecting rod 106, it can more accurately guide cables at different installation heights and angles, further enhancing the device's adaptability to complex construction scenarios.

[0044] Reference Figures 5-6 As shown, the steering mechanism 400 includes: a first drive rod 402, a second drive rod 403, and a slide rod 405; wherein,

[0045] The connecting rod 106 is hinged to the mounting plate 104 via a rotating shaft 404, and a drive motor 401 is fixedly mounted on the mounting plate 104. The output shaft of the drive motor 401 is vertically downward and a first drive rod 402 is fixedly mounted at its top. A second drive rod 403 is hinged to one end of the first drive rod 402. The second drive rod 403 is hinged to the rotating shaft 404, and multiple sets of slide rods 405 connected to the sides of the connecting rod 106 are respectively provided on both sides of the rotating shaft 404 on the mounting plate 104.

[0046] When the cable guide direction needs to be adjusted, the drive motor 401 is started. The output shaft of the drive motor 401 drives the first drive rod 402 to rotate around its fixed point. The second drive rod 403, which is hinged to one end of the first drive rod 402, will swing as the first drive rod 402 rotates. Since the second drive rod 403 is hinged to the rotating shaft 404, the swing of the second drive rod 403 will push the rotating shaft 404 to rotate, thereby driving the connecting rod 106 connected to the rotating shaft 404 to swing around the hinge point. During the swing of the connecting rod 106, the slide rods 405 located on both sides of the rotating shaft 404 on the mounting plate 104 play a key role. The slide bar 405 is connected to the side of the connecting rod 106. On the one hand, it provides stable support and guidance for the swing of the connecting rod 106, preventing it from swaying or deviating during swing. On the other hand, the sliding engagement of the slide bar 405 assists the connecting rod 106 to rotate smoothly along a predetermined trajectory, ensuring that the fixing sleeve 107 and the through hole 108 are accurately adjusted to the required position and angle, thereby achieving precise control over the cable guiding direction. When the predetermined guiding angle is reached, the drive motor 401 stops working, completing the adjustment of the cable guiding direction, and the cable moves along the new guiding path during subsequent traction.

[0047] Reference Figures 1-4 As shown, a hydraulic rod 109 is hinged to the fixed frame 103, and the output end of the hydraulic rod 109 is hinged to the bottom surface of the mounting plate 104.

[0048] When installing the cable pulling device or adjusting the position of the mounting plate 104 according to actual construction needs, the hydraulic rod 109 is activated. The hydraulic system of the hydraulic rod 109 starts working, and the output end of the hydraulic rod 109 extends and retracts due to the pressure change of the hydraulic oil. Since one end of the hydraulic rod 109 is hinged to the fixed frame 103 and the other end is hinged to the bottom surface of the mounting plate 104, the extension and retraction of the output end of the hydraulic rod 109 will cause the mounting plate 104 to rotate around the hinge point with the fixed frame 103. When the output end of the hydraulic rod 109 extends, the mounting plate 104 rotates upward around the hinge point, increasing the angle between the mounting plate 104 and the fixed frame 103, thereby increasing the height and tilt angle of the mounting plate 104; when the output end of the hydraulic rod 109 shortens, the mounting plate 104 rotates downward around the hinge point, decreasing the angle between the mounting plate 104 and the fixed frame 103, and reducing the height and tilt angle of the mounting plate 104. Operators can precisely adjust the height and angle of the mounting plate 104 by controlling the extension and retraction of the hydraulic rod 109 according to the actual needs of cable installation, so that the guide roller 105, clamping mechanism 200, limiting mechanism 300 and other components on the mounting plate 104 are in a suitable working position, providing the best working conditions for cable installation and traction.

[0049] Reference Figures 1-6As shown, the guide roller 105, clamping roller 205, upper pressure roller 304 and fixed roller 305 are all spindle-shaped, with large ends and small middle.

[0050] When the cable enters the cable installation traction device, it first contacts the guide roller 105. Since the guide roller 105 is spindle-shaped (large at both ends and small in the middle), the cable naturally slides into the middle position of the guide roller 105. This position provides a stable guiding channel for the cable, keeping it centered during its forward movement. When the cable reaches the clamping mechanism 200, the clamping roller 205 is also spindle-shaped. When the rotary motor 201 drives the bidirectional screw 203 to rotate, causing the threaded block 204 and the clamping roller 205 to move towards each other to clamp the cable, the spindle-shaped clamping roller 205 can better conform to the cable surface, applying uniform pressure from both sides of the cable to ensure it is firmly clamped. Then, the cable passes through the limiting mechanism 300. The spindle-shaped structure of the upper pressure roller 304 and the fixed roller 305 stably limits the cable between them. The upper pressure roller 304 presses down on the cable under the action of the spring 303, and cooperates with the fixed roller 305. The spindle-shaped design makes it difficult for the cable to slip off from both sides, ensuring that the cable moves along the predetermined path during the traction process.

[0051] Reference Figures 1-4 As shown, the bottom surface of the base 100 is fixedly provided with multiple sets of self-locking casters 101 at intervals, and a push handle 102 is fixedly provided on the base 100.

[0052] When it is necessary to move the cable installation traction device, the operator holds the push handle 102 to unlock the self-locking caster wheel 101. Because the caster wheel 101 is rotatable, the operator can easily push the device in all directions to transport it to the required working position. Once at the working position, the operator steps on or operates the self-locking device of the caster wheel 101 to lock it, fixing the device in its current position and preventing movement during cable installation traction operations.

[0053] In summary, the cable installation and traction device provided by this utility model, when in use, starts the hydraulic rod 109, and the output end of the hydraulic rod 109 is extended and retracted by the change of hydraulic oil pressure, which drives the mounting plate 104 to rotate around the hinge point with the fixed frame 103. The height and tilt angle of the mounting plate 104 are precisely adjusted according to the actual construction needs, so that the components on the mounting plate 104 are in a suitable working position. The cable is passed through the guide roller 105. The multiple sets of spaced spindle-shaped guide rollers 105 use their structure of being large at both ends and small in the middle to guide the cable to slide into the middle position, initially guiding the cable and keeping it centered. Then, the rotary motor 201 is started, and its output shaft drives the bidirectional screw 203 to rotate. Because the two sections of the bidirectional screw 203 have opposite threads, the two threaded blocks 204, under the limit of the guide groove 202, drive the clamping rollers 205 to move towards each other, squeezing the cable from both sides until the cable is firmly clamped. Simultaneously, two adjacent sets of bidirectional screws 203 are driven by a transmission belt 206 to ensure that multiple clamping mechanisms 200 operate synchronously, clamping the cable evenly and stably. After the cable enters the limiting mechanism 300, it is positioned between the upper pressure roller 304 and the fixed roller 305. The spring 303 is in a natural elastic state, causing the upper pressure roller 304 to apply downward pressure, tightly clamping the cable. During the traction process, if the cable deviates, the upper pressure roller 304 slides up and down in the groove 302, and the spring 303 provides a reverse force by compression or extension, ensuring that the cable is on the predetermined guide path. If it is necessary to adjust the cable guide direction, the drive motor 401 is started, and its output shaft drives the first drive rod 402 to rotate in a circle. The first drive rod 402 drives the second drive rod 403 to swing, and the second drive rod 403 pushes the rotating shaft 404 to rotate, thereby driving the connecting rod 106 to swing around the hinge point. The slide bar 405 on the mounting plate 104 provides support and guidance for the connecting rod 106, assisting it to rotate smoothly, so that the fixing sleeve 107 and the through hole 108 can be adjusted to the required position and angle, thus completing the cable guiding direction adjustment.
