[0030] Reference Figures 1-6 A portable cable pulling device for power construction, comprising:

[0031] A first movable frame 1 is provided, and a second movable frame 6 is provided on one side opposite to the first movable frame 1. The top two sides of the first movable frame 1 are hinged to the first connecting rods 2, and the other ends of the first connecting rods 2 are slidably connected to the side walls of the second movable frame 6. The top two sides of the second movable frame 6 are hinged to the second connecting rods 3, and the other ends of the second connecting rods 3 are slidably connected to the first movable frame 1. The distance between the first movable frame 1 and the second movable frame 6 can be adjusted according to the actual use, so that the first movable frame 1 and the second movable frame 6 can be unfolded in use; when not in use, the first movable frame 1 and the second movable frame 6 can be folded together to reduce the footprint and achieve portable transportation.

[0032] The first connecting rod 2 and the second connecting rod 3 on both sides intersect and are rotatably connected in the middle section. A load-bearing rod 4 is rotatably connected between the intersection of the first connecting rod 2 and the second connecting rod 3 on both sides. In use, it is used to support the cable winding reel, so that the cable winding reel can be unloaded outward.

[0033] The second movable frame 6 is equipped with a traction mechanism 9, which is used to connect with the end of the cable reel to pull the cable for unloading. The end face of the second movable frame 6 opposite to the first movable frame 1 is equipped with a drive assembly 8 for controlling the movement of the traction mechanism 9, which is used to control the movement of the traction mechanism 9 through the drive assembly 8, so that the traction mechanism 9 can perform the unloading operation in a controlled manner.

[0034] Furthermore, a width adjustment assembly 5 is installed on the first movable frame 1. The width adjustment assembly 5 includes a lead screw 51 installed longitudinally along the central axis of the first movable frame 1. One bottom end of the lead screw 51 passes through the frame of the first movable frame 1 and is connected to a drive motor 53. A driveable sliding connecting plate 52 is installed on the lead screw 51. The two ends of the connecting plate 52 are hinged to the second connecting rods 3 slidably installed on both sides of the first movable frame 1. The connecting plate 52 is used to drive the lead screw 51 to rotate through the drive motor 53, so that the lead screw 51 drives the connecting plate 52 installed on its rod to move along the axial direction of the lead screw 51, thereby driving the second connecting rods 3 on both sides of the connecting plate 52 to move. The first movable frame 1 slides, and the other end of the second connecting rod 3 is hinged to the second movable frame 6, thereby enabling the second movable frame 6 to move closer to or away from the first movable frame 1. The second connecting rod 3 is driven by the drive motor 53, thereby driving the second movable frame 6 to move. The movement of the second movable frame 6 causes the first connecting rod 2, which is slidably connected to the second movable frame 6, to follow synchronously and automatically adjust the distance between the first movable frame 1 and the second movable frame 6 in a controlled manner. It can be folded and stored according to the actual situation to achieve portable transportation or adjust the width between the first movable frame 1 and the second movable frame 6, thereby adapting to the installation of cable reels of different diameters.

[0035] Furthermore, the axial ends of the load-bearing rod 4 are provided with external threads 41 after passing through the intersection points formed by the intersection of the first connecting rod 2 and the second connecting rod 3 on both sides. The two ends of the load-bearing rod 4 are respectively connected to detachable anti-reverse rings 42 through the external threads 41. In use, the first movable frame 1 and the second movable frame 6 are adjusted to the corresponding width, so that the coil winding bracket is placed between the first movable frame 1 and the second movable frame 6. One end of the load-bearing rod passes through the intersection point formed by the intersection of the first connecting rod 2 and the second connecting rod 3 on one side, and then passes through the center hole of the cable winding reel and overlaps with the intersection point on the other side. The load-bearing rod 4 lifts the cable winding reel so that it can rotate relative to the load-bearing rod 4, which facilitates the wire unwinding. The two ends of the load-bearing rod 4 are respectively connected to anti-reverse rings through the external threads 41 to prevent the load-bearing rod 4 from slipping during use.

[0036] Furthermore, the traction mechanism 9 includes a winding assembly 91 and a tensioning assembly 92 disposed directly above the winding assembly 91. The tensioning assembly 92 elastically abuts against the winding assembly 91. The drive assembly 8 is drivenly connected to the winding assembly 91. In use, the cable passes between the winding assembly 91 and the tensioning assembly 92. The tensioning assembly 92 is used to press down the cable, so that the cable is in full contact with the winding assembly 91, thereby increasing the surface friction between the cable and the winding assembly 91. The winding assembly 91 is used to push the cable to move under the control of the drive assembly 8, thereby unwinding the cable.

[0037] Furthermore, the winding assembly 91 includes a pay-off roller 911 rotatably mounted in the middle of the second movable frame 6. One end of the pay-off roller 911 is provided with a driven tooth 914. The drive assembly 8 includes a drive tooth 84, which meshes with the driven tooth 914. In use, the drive tooth 84 rotates to drive the driven tooth 914 to rotate, thereby driving the pay-off roller 911 to rotate, and the pay-off roller 911 pushes the cable to move.

[0038] Furthermore, the drive assembly 8 includes a fixed frame 81, which is fixedly connected to the front end face of the second movable frame 6 away from the first movable frame 1. A handwheel 85 is mounted on the front end face of the fixed frame 81. The other end of the handwheel 85 rotatably passes through the fixed frame 81 and is connected to a drive bevel gear. The fixed frame 81 also has a driven bevel gear 82 that meshes with the drive bevel gear. The other end of the driven bevel gear 82 is fixedly connected to a transmission shaft 83. The other end of the transmission shaft 83 rotatably passes through the side wall of the fixed frame 81 and is fixedly connected to the drive gear 84. In use, the handwheel 85 is connected to the drive bevel gear. Rotating the handwheel 85 causes the drive bevel gear to mesh with the driven bevel gear 82. The driven bevel gear 82 is fixedly connected to the drive gear 84 through the transmission shaft 83, transmitting the driving force to the drive gear 84, thereby driving the winding assembly 91 to work and realizing precise control of the pay-off roller 911.

[0039] Furthermore, the wire feeding roller 911 has a recessed first wire groove 912 around its outer periphery, and an anti-slip ring 913 is provided around the outer contour surface of the first wire groove 912. In use, the first wire groove 912 is used to guide the cable, and the anti-slip ring 913 increases the friction between the cable and the wire feeding roller 911 to prevent the cable from slipping during the wire feeding process.

[0040] Furthermore, the tensioning assembly 92 includes two sets of sleeves 921 whose top ends are fixedly connected to the second movable frame 6. The bottom of the two sets of sleeves 921 is slidably connected to a telescopic movable rod 922. An elastic element is provided between the movable rod 922 and the corresponding sleeve 921. A rotating shaft is provided between the two sets of movable rods 922. A tensioning roller 923 that elastically abuts against the pay-off roller 911 is rotatably mounted in the middle of the rotating shaft. In use, the elastic element between the sleeve 921 and the movable rod 922 provides the tensioning roller 923 with longitudinal elastic adjustment space. The elastic element pushes the tensioning roller 923 to press down the cable. Due to the presence of the elastic element, it can be ensured that cables of different diameters can fully contact the first guide groove 912 of the pay-off roller 911, so that there is always friction between the pay-off roller 911 and the cable.

[0041] Furthermore, the tension roller 923 has a recessed second guide groove 924 around its outer peripheral end face to guide the cable, so that the cable can stably pass through the channel formed between the second guide groove 924 of the tension roller 923 and the first guide groove 912 of the pay-off roller 911 during the movement, preventing the cable from deviating and causing traction failure.

[0042] Furthermore, both sides of the bottom of the first movable frame 1 and the second movable frame 6 are equipped with casters 7, which facilitates the movement of the entire device during the cable laying process, thereby laying the cable according to the predetermined route. At the same time, it is easy to transport the device, improving its portability and flexibility.

[0043] Working principle: In use, first unfold the first movable frame 1 and the second movable frame 6 from their folded state. Adjust the first connecting rod 2 and the second connecting rod 3 to make the distance between them suitable for placing the cable winding reel. Install the load-bearing rod 4 to lift the cable winding reel. The two ends of the load-bearing rod 4 are connected to the intersection points formed by the intersection of the first connecting rod 2 and the second connecting rod 3 on both sides. The two ends of the load-bearing rod 4 are connected to the anti-reverse ring 42 through the external thread 41 to prevent the cable winding reel from slipping. Pass the cable end of the cable winding reel through the channel formed between the second guide groove 924 of the tension roller 923 and the first guide groove 912 of the unwinding roller 911. The tension roller 923 presses down on the cable, increasing the friction between the cable and the first guide groove 912 of the unwinding roller. When unwinding, turn the handwheel 85. 85 drives the drive bevel gear to rotate, and the drive bevel gear meshes with the driven bevel gear 82. The driven bevel gear 82 drives the drive gear 84 to rotate through the transmission shaft 83. The drive gear 84 meshes with the driven gear 914 on the winding assembly 91, thereby driving the pay-off roller 911 of the winding assembly 91 to rotate, thereby gradually pushing the cable outward. The cable winding reel is pulled by the cable and rotates on the load-bearing rod 4, sequentially paying off the cable and fixing the cable end at the starting point of the cable laying path. This pushes the entire device to move along the cable laying path to realize the cable laying along the path. During the pay-off process, the cable moves outward through the driving action of the pay-off roller 911, thereby avoiding excessive pulling on the cable and the fixed end of the cable during the movement of the traction device along the laying path, which would cause cable deformation.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
