Conversely, the second pay-off roller can be quickly disassembled, achieving the effect of taking in and feeding multiple sets of cable reels at once. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 One embodiment provided by this utility model: An adjustable-angle cable-laying frame for power construction, comprising: The frame includes an adjustable wire feeding frame 1. A first wire feeding roller 11 is provided on the surface of the adjustable wire feeding frame 1, and a second wire feeding roller 12 is provided on the surface of the first wire feeding roller 11. The adjustable wire feeding frame 1, the first wire feeding roller 11, and the second wire feeding roller 12 are all existing products and are not considered as technical protection points of this application. They will not be described in detail here. The first wire feeding roller 11 and the second wire feeding roller 12 have the same structure. For the convenience of describing the splicing mechanism, they are labeled separately in this application. The tensioning mechanism includes a tension knob 2, which is rotatably connected to the surface of the first pay-off roller 11 to drive the worm gear 21 to rotate. The worm gear 21 is fixedly connected to the surface of the tension knob 2 to drive the worm wheel 23 to rotate. A fixed shaft 22 is fixedly connected inside the first pay-off roller 11 to connect the worm wheel 23. The worm gear 23 is meshed with the surface of the worm gear 21 to connect the connecting screw 24. The connecting screw 24 is fixedly connected to the surface of the worm wheel 23 to drive the adjusting block 25 to move through its own rotation. The adjusting block is threadedly sleeved onto the surface of the connecting screw 24. 25 is used to move the tensioning block 27 by its own movement. The surface of the adjusting block 25 is hinged with a hinge rod 26 for connecting the adjusting block 25 and the tensioning block 27. The end of the hinge rod 26 away from the adjusting block 25 is hinged with the tensioning block 27 for tensioning the cable reel. The surface of the tensioning block 27 is fixedly connected with a limit block 28 for limiting the movement position of the tensioning block 27. The surface of the first feed roller 11 is provided with a guide groove 29 for guiding the movement of the tensioning block 27. A limit groove 210 is provided inside the guide groove 29 for limiting the movement position of the limit block 28.

[0019] Furthermore, the tension knobs 2 are symmetrically distributed in two sets on the surface of the first wire feeding roller 11. The tension knobs 2 are distributed at both ends of the first wire feeding roller 11, so that the tension of the cable reel can be controlled from both ends. The worm gear 21 is rotatably connected to the inside of the first wire feeding roller 11 through the tension knobs 2. Rotating the tension knobs 2 drives the worm gear 21 to rotate.

[0020] Furthermore, the worm gear 23 is rotatably connected to the surface of the worm 21 and the fixed shaft 22, and the connecting screw 24 is rotatably connected to the inside of the first feed roller 11 through the worm gear 23. The worm gear 23 rotates on the surface of the fixed shaft 22 following the rotation of the worm 21, thereby driving the connecting screw 24 to rotate inside the first feed roller 11. The worm 21 and the worm gear 23 are self-locking structures and will not rotate without the action of external force.

[0021] Furthermore, the adjusting block 25 is internally and movably connected to the connecting screw 24 and the guide groove 29. The tensioning blocks 27 are evenly distributed in four groups on the surface of the adjusting block 25. The tensioning blocks 27 are movably connected to the surface of the adjusting block 25 through the hinge rod 26. The adjusting block 25 moves inside the guide groove 29 as the connecting screw 24 rotates, thereby driving the hinge rod 26 to rotate, causing the tensioning blocks 27 to move on the surface of the first wire feeding roller 11, thereby tensioning the cable reel.

[0022] Furthermore, the limiting grooves 210 are evenly arranged in four groups inside the limiting grooves 210. The limiting block 28 is movably connected to the inside of the limiting groove 210 through the tensioning block 27. The limiting block 28 moves inside the limiting groove 210 as the tensioning block 27 moves, thereby limiting the movement position of the tensioning block 27.

[0023] Furthermore, the quick-release connection mechanism includes a connecting rod 3, which is fixedly connected to the surface of the first feed roller 11 for connecting and mounting the insertion rod 35. A movable sleeve 31 is movably connected to the surface of the connecting rod 3 for driving the extrusion ring 32 to move. The extrusion ring 32 is fixedly connected inside the movable sleeve 31 for extruding the limiting ball 34. A damping spring 33 is wound around the surface of the connecting rod 3 for driving the extrusion ring 32 to reset through its own deformation. The limiting ball 34 is movably connected to the surface of the connecting rod 3 for abutting against the slot 36. An installation insertion rod 35 is fixedly connected to the surface of the second feed roller 12 for mounting on the connecting rod 3. The surface of the installation insertion rod 35 has a slot 36 for connecting the limiting ball 34.

[0024] Furthermore, the limiting balls 34 are evenly distributed in six groups on the surface of the connecting rod 3. The extrusion ring 32 abuts against the surface of the limiting balls 34. The extrusion ring 32 is movably connected to the surface of the connecting rod 3 through the movable sleeve 31. The mounting rod 35 is inserted into the surface of the first wire feeding roller 11 through the connecting rod 3. The surface of the connecting rod 3 is provided with a movable groove for connecting the limiting balls 34. Moving the movable sleeve 31 causes the extrusion ring 32 to leave the surface of the limiting balls 34. The damping spring 33 deforms accordingly, and then the mounting rod 35 can be inserted into the surface of the connecting rod 3.

[0025] Furthermore, the two ends of the damping spring 33 are fixedly connected to the surfaces of the connecting rod 3 and the compression ring 32. The compression ring 32 is movably connected to the surfaces of the connecting rod 3 through the damping spring 33. The slots 36 are evenly distributed in six groups on the surface of the mounting rod 35. The limiting ball 34 is connected to the surface of the compression ring 32 and the slot 36. When the restriction on the movable sleeve 31 is released, the damping spring 33 drives the compression ring 32 to reset in order to restore its original shape, thereby pressing against the surface of the limiting ball 34, so that the limiting ball 34 abuts against the surface of the slot 36, thereby fixing the installation position of the mounting rod 35, so that the first wire feeding roller 11 and the second wire feeding roller 12 are connected together, thereby achieving the effect of simultaneously performing wire feeding and take-up operations on multiple sets of cable reels. Conversely, the movable sleeve 31 can be moved to achieve the effect of quickly disassembling and installing the mounting rod 35.

[0026] Working principle: When using the adjustable cable reel 1, first place the cable reel on the surface of the first cable reel 11 and the second cable reel 12. Then, rotate the tension knob 2 to drive the worm gear 21 to rotate. The worm wheel 23 follows the rotation of the worm gear 21 and rotates on the surface of the fixed shaft 22, thereby driving the connecting screw 24 to rotate inside the first cable reel 11. The adjusting block 25 follows the rotation of the connecting screw 24 and moves inside the guide groove 29, thereby driving the hinge rod 26 to rotate, causing the tensioning block 27 to move on the surface of the first cable reel 11, thereby tensioning the cable reel. The limiting block 28 follows the movement of the tensioning block 27 and moves inside the limiting groove 210, thereby limiting the movement position of the tensioning block 27. Then, the first cable reel 12 is placed on the surface of the first cable reel 11 and the second cable reel 12. The first and second pay-off rollers 11 and 12 are connected together. The movable sleeve 31 moves the extrusion ring 32 away from the surface of the limiting ball 34, and the damping spring 33 deforms accordingly. Then, the mounting rod 35 can be inserted into the surface of the connecting rod 3, releasing the restriction on the movable sleeve 31. The damping spring 33 returns to its original shape, causing the extrusion ring 32 to reset, thereby pressing against the surface of the limiting ball 34, so that the limiting ball 34 abuts against the surface of the slot 36, thereby fixing the installation position of the mounting rod 35, so that the first pay-off roller 11 and the second pay-off roller 12 are connected together, thereby achieving the effect of simultaneously performing take-up and pay-off operations on multiple sets of cable reels. Conversely, the movable sleeve 31 can be moved to achieve the effect of quickly disassembling and installing the mounting rod 35.
