[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] like Figures 1 to 4As shown, a power line tensioner for electrical construction according to the present invention includes a housing 1, a first gear 2, a rotating shaft 3, two sets of bearings 4, four sets of sliders 5, four sets of slide rails 6, two sets of racks 7, two sets of hooks 8, two sets of mounting plates 9, multiple sets of bolts 10, and a limiting device. The housing 1 has working grooves in its center, left, and right parts. The first gear 2 is installed in the center of the rotating shaft 3 and located inside the housing 1. The two sets of bearings 4 are respectively installed at the left and right ends of the grooves in the center of the housing 1. The rotating shaft 3 is rotatably mounted on the housing 1 via the two sets of bearings 4. The four sets of sliders 5 are respectively installed on the upper left, upper right, lower left, and lower right sides of the grooves in the center of the housing 1. The four sets of slide rails 6 are respectively installed on the two sets of racks 7. The two sets of racks 7 are slidably installed at the top and bottom ends of the grooves in the center of the housing 1. The two sets of racks 7 mesh with the first gear 2. The two sets of hooks 8 are respectively installed at one end of the two sets of racks 7 and located outside the housing 1. The top and bottom of the housing 1 are connected to the first gear 2. The bottom end is connected to an installation port. Two sets of mounting plates 9 are respectively installed at the openings at the top and bottom of the housing 1 by multiple sets of bolts 10. Two sets of limiting devices are respectively installed at the top of the left and right slots inside the housing 1, and the two sets of limiting devices are connected to the rotating shaft 3. One end of each set of wires is fixed to one set of hooks 8, and the other end of each set of wires is fixed to the building. Then the rotating shaft 3 is rotated, which drives the first gear 2 to rotate. The first gear 2 meshes with two sets of spur racks 7. The four sets of slide rails 6 on the two sets of spur racks 7 slide on the four sets of sliders 5. The two sets of spur racks 7 slide on the housing 1. The two sets of spur racks 7 drive the two sets of hooks 8 to slide inward. The two sets of hooks 8 tighten the two sets of wires, which is convenient for tightening the wires. The two sets of limiting devices limit the rotating shaft 3. By setting this device, the operation is simple and it is convenient to assemble the parts inside the housing 1, which improves its practicality.

[0020] The present invention discloses a tensioner for power construction, comprising a limiting device including a second gear 11, a limiting pin 12, a pull rod 13, a slide tube 14, and a spring 15. The second gear 11 is mounted on a rotating shaft 3, and the limiting pin 12 meshes with the second gear 11. The limiting pin 12 is mounted on the bottom end of the pull rod 13, and the slide tube 14 is mounted on an upper mounting plate 9. The pull rod 13 slides within the slide tube 14. One end of the spring 15 is connected to the top end of the limiting pin 12, and the other end of the spring 15 is connected to the bottom end of the upper mounting plate 9. When the rotating shaft 3 rotates, it drives two sets of second gears 11 to rotate, and the rotation of the two sets of second gears 11 engages with two sets of limiting pins 12. When pins 12 are engaged, the two sets of limiting pins 12 cause the two sets of springs 15 to deform elastically. The two sets of springs 15 then push the two sets of limiting pins 12 inward to lock the two sets of second gears 11, thereby locking the two sets of wires. When it is necessary to loosen the two sets of wires, the two sets of pull rods 13 slide within the two sets of slide tubes 14. The two sets of pull rods 13 drive the two sets of limiting pins 12 to move upward. The two sets of springs 15 deform elastically, and the two sets of limiting pins 12 separate from the two sets of second gears 11, thereby loosening the wires. This also serves to limit the rotation shaft 3 and lock the wires.

[0021] The present invention provides a wire tensioner for power construction, which further includes two sets of movable rods 16, two sets of conical plugs 17, and two sets of nuts 18. Each of the two sets of straight racks 7 has an internal cavity. Two sets of hooks 8 are respectively installed at one end of each of the two sets of slide rails 6. The other ends of the two sets of movable rods 16 pass through the two sets of conical plugs 17 and slide within the cavities of the two sets of straight racks 7. The two sets of movable rods 16 and the two sets of conical plugs 17 are slidably connected. Each of the two sets of straight racks 7 has a connecting tube at one end, and the outer end of each connecting tube has an external thread. The two sets of conical plugs 17 are respectively installed on the outer ends of the connecting tubes of the two sets of straight racks 7. At the end, two sets of nuts 18 are located outside the two sets of conical plugs 17, and the two sets of nuts 18 are screwed to the two sets of connecting tubes on the two sets of straight racks 7. The length of the two sets of moving rods 16 is adjusted by sliding them in the cavities of the two sets of straight racks 7. When the length of the two sets of moving rods 16 is slid to the working position, the two sets of nuts 18 are rotated, and the two sets of nuts 18 are screwed to the connecting tubes of the two sets of straight racks 7, thereby fixing the two sets of moving rods 16. This can be used to adjust the tightness of the two sets of wires, and can be applied to different working sites, improving its practicality.

[0022] The present invention provides a tensioner for power construction, which further includes two sets of limiting plates 19. The two sets of limiting plates 19 are respectively installed on the lower front side and the upper rear side of the central groove inside the housing 1. The two sets of limiting plates 19 correspond to the positions of two sets of straight racks 7. By setting the limiting plates 19, the straight racks 7 can be limited.

[0023] The present invention provides a tensioner for power construction, which further includes two sets of rocker plates 20, which are respectively installed on the left and right ends of the rotating shaft 3; by setting the rocker plates 20, it is easier to rotate the rotating shaft 3 and improves convenience.

[0025] The present invention provides a tensioner for power construction, which also includes a handle 22, which is installed at the top of two sets of pull rods 13; by setting the handle 22, it is convenient to operate the two sets of pull rods 13 and improves convenience.

[0026] The present invention provides a tensioner for power construction, wherein the rocker plate 20 is provided with a rotating rod; this facilitates the gripping and operation of the rocker plate 20.

[0027] This invention discloses a wire tensioner for power construction. During operation, two sets of movable rods 16 are first slid within the cavities of two sets of straight racks 7 to adjust their length. When the lengths of the two sets of movable rods 16 are slid to the working position, two sets of nuts 18 are rotated, which then screw onto the connecting pipes of the two sets of straight racks 7, thereby fixing the two sets of movable rods 16. Next, one end of each set of two sets of wires is fixed to one set of hooks 8, and the other end of each set of wires is fixed to a building. Then, the rotating shaft 3 is rotated, which drives the first gear 2 and two sets of second gears 11 to rotate. When the first gear 2 rotates, it meshes with two sets of spur racks 7. The four sets of slide rails 6 on the two sets of spur racks 7 slide on the four sets of sliders 5. The two sets of spur racks 7 slide on the housing 1. The two sets of spur racks 7 drive the two sets of hooks 8 to slide inward. The two sets of hooks 8 tighten the two sets of wires. When the two sets of second gears 11 rotate, they mesh with two sets of limit pins 12. The two sets of limit pins 12 cause the two sets of springs 15 to deform elastically. The two sets of springs 15 push the two sets of limit pins 12 to move inward so that they lock the two sets of second gears 11, thereby locking the two sets of wires.
