DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, an overhead line cable tension detection device includes a support frame 1, two connecting plates 2 are movably provided on both sides of the support frame 1, and a movable frame 3 is fixedly installed on the opposite side of the adjacent connecting plates 2. The two movable frames 3 are movably provided with a mounting frame 4 on the end away from the support frame 1, and a rotating wheel 5 is rotatably installed between the inner walls of the two mounting frames 4.

[0026] An electric guide rail 6 is fixedly installed on one side of the support frame 1 , a pressure sensor 7 is provided at the movable end of the electric guide rail 6 , a display screen 8 is provided on one side of the upper surface of the electric guide rail 6 , and the display screen 8 is electrically connected to the pressure sensor 7 .

[0027] A slide groove 9 is provided on the upper surface of the support frame 1. Two sliders 10 are slidably provided in the slide groove 9. Adjacent connecting plates 2 are fixedly mounted on both sides of the corresponding sliders 10.

[0028] A bidirectional screw rod 11 is rotatably installed between the two sides of the inner wall of the slide groove 9, and two sliders 10 are respectively threadedly arranged on both sides of the rod body of the bidirectional screw rod 11.

[0029] A first pulley 12 is sleeved on the middle of the bidirectional screw rod 11, a vertical plate 13 is fixedly installed on the middle of the upper surface of the support frame 1, a rotating rod 14 is rotatably installed on one side of the vertical plate 13, and a second pulley 15 is sleeved on one side of the rotating rod 14. A transmission belt 16 is sleeved on the surface of the first pulley 12 and the second pulley 15.

[0030] One end of the rotating rod 14 passes through the vertical plate 13 and is fixedly mounted with a first hand wheel 17 .

[0031] The staff passes the cable through the support frame 1, and then makes the two ends of the cable segment to be measured fit with the rotating wheel 5. Then the staff starts the electric guide rail 6, so that its moving end drives the pressure sensor 7 to move, so that the pressure sensor 7 pushes the cable segment. Under the pushing action of the pressure sensor 7 and the cooperation of the rotating wheel 5, the cable segment is tightened, and the pressure sensor 7 feeds back the thrust value to the screen of the display screen 8, which is convenient for the staff to detect the tension of the cable segment. When it is necessary to detect cable segments of different distances, the staff controls the pressure sensor 7 to reset, and then the staff rotates the first handwheel 17 to drive the rotating rod 14 and the second pulley 15 to rotate. Under the transmission action of the transmission belt 16, the first pulley 12 drives the bidirectional screw rod 11 to rotate. The rotating bidirectional screw rod 11 drives the two sliders 10 and the two rotating wheels 5 to move relative to each other along the direction of the slide groove 9 by screwing in the thread, so that the staff can adjust the distance between the two rotating wheels 5 according to the length of the cable segment to be measured, so that the staff can accurately measure the tension of the cable, which can meet the actual application needs.

[0032] In another embodiment of the present invention, a movable groove 18 is formed on the surface of one end of each movable frame 3 away from the supporting frame 1, and a movable block 19 is slidably arranged in each of the two movable grooves 18, and one side of the two movable blocks 19 is fixedly connected to the corresponding mounting frame 4 respectively;

[0033] A cross bar 20 is fixedly installed between both sides of the inner walls of the two moving grooves 18, and two moving blocks 19 are slidably arranged on one side of the corresponding cross bar 20.

[0034] The top surfaces of the two moving grooves 18 are penetrated by an avoidance groove 21. The upper surfaces of the two moving blocks 19 are fixedly mounted with racks 1901 through pads 22. A fixing plate 23 is fixedly mounted on one side of the upper surface of the two moving frames 3. A connecting shaft 24 is rotatably mounted on one side of the two fixing plates 23. The shafts of the two connecting shafts 24 are sleeved with gears 25, and the two gears 25 are meshed with the corresponding racks 1901.

[0035] One end of the two connecting shafts 24 passes through the corresponding fixing plates 23 and is fixedly mounted with a second hand wheel 26 .

[0036] The staff rotates the second hand wheel 26 to drive the connecting shaft 24 to rotate. Under the meshing action of the gear 25 and the rack 1901, the moving block 19 moves along the moving groove 18, allowing the staff to precisely adjust the moving distance of the wheel 5. Through the combination of coarse adjustment of the bidirectional screw 11 and fine adjustment of the gear 25 and the rack 1901, the optimal spacing between the wheels 5 can be found more quickly, thereby improving detection efficiency and reducing detection time and cost.

[0037] In another embodiment of the present invention, two first rubber blocks 27 are fixedly mounted on one side of the support frame 1 , and second rubber blocks 28 are fixedly mounted on both sides of the electric guide rail 6 .

[0038] By providing the first rubber block 27 and the second rubber block 28 , the support frame 1 and the electric guide rail 6 can be supported, making it convenient for workers to operate.

[0039] The working principle of this overhead line cable tension detection device:

[0040] When in use, the staff passes the cable through the support frame 1, and then makes the two ends of the cable segment to be measured fit with the rotating wheel 5. Then the staff starts the electric guide rail 6, so that its moving end drives the pressure sensor 7 to move, so that the pressure sensor 7 pushes the cable segment. Under the pushing action of the pressure sensor 7 and the cooperation of the rotating wheel 5, the cable segment is tightened, and the pressure sensor 7 feeds back the thrust value to the screen of the display screen 8, which is convenient for the staff to detect the tension of the cable segment. When it is necessary to detect cable segments of different distances, the staff resets the pressure sensor 7 by controlling the pressure sensor 7. Then the staff rotates the first handwheel 17 to drive the rotating rod 14 and the second pulley 15 to rotate. Under the transmission action of the transmission belt 16, the first pulley 12 drives the bidirectional screw rod 11 to rotate. The rotating bidirectional screw rod 11 drives the two sliders 10 and the two rotating wheels 5 to move relative to each other along the direction of the slide groove 9 by screwing in the thread, so that the staff can adjust the distance between the two rotating wheels 5 according to the length of the cable segment to be measured, so that the staff can accurately measure the tension of the cable, which can meet the actual application needs.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
