[0026] The support mechanism 4 includes a first gear 41 and a fixed pulley 46. The rear side of the first gear 41 is rotatably connected to the front side of the mechanism column 1 near the upper side, and two first gears 41 are symmetrically distributed on the left and right. Two first winding wheels 42 are rotatably connected to the left and right sides of the mechanism column 1 near the upper side. The front side of each of the two first winding wheels 42 is fixedly connected to a second gear 43. A locking component 44 is movably installed between the rear side of the first gear 41 on the right side and the mechanism column 1. The inner side of each of the two first winding wheels 42 is wound with a first traction rope 45. The outer side of the first traction rope 45 overlaps the inner side of the fixed pulley 46. The end of each of the two first traction ropes 45 away from the first winding wheel 42 is fixedly connected to a clamp 47.
[0027] It should be noted that there are two fixed pulleys 46 distributed in the front and rear, and the front and rear sides of the fixed pulleys 46 are rotatably connected to the upper inner side of the clamping plate 31. The first gear 41 and the second gear 43 are meshed together. Rotating the first gear 41 causes the second gear 43 to drive the first winding wheel 42 to rotate, thereby causing the first traction rope 45 to be wound or extended on the first winding wheel 42. The clamp 47 is used to fix it to the cable. In this way, the cable is lifted by the first traction rope 45, so as to prevent the cable from drooping and causing the cable to sway in windy weather.
[0028] like Figure 3 As shown, the fastening mechanism 3 includes a clamping plate 31. The outer side of the clamping plate 31 is movably sleeved on the inner side of the mechanism column 1. Two limiting rods 33 distributed on the left and right are movably sleeved on the inner side of the clamping plate 31 near the bottom. The lower end of the limiting rods 33 is fixedly connected to a clamping plate 32. Two springs 34 distributed on the left and right are movably sleeved on the inner side of the clamping plate 31 near the bottom, and the springs 34 are located on the upper side of the limiting rods 33.
[0029] It should be noted that after the clamping plate 31 is inserted into the inner side of the mechanism column 1, the cable is placed between the inner side of the mechanism column 1 and the clamping plate 32. The spring 34 pushes down the limiting rod 33, so that the clamping plate 32 can fix both thicker and thinner cables.
[0030] like Figure 3As shown, the inner side of the clamping plate 31 movably sleeves two top blocks 36 symmetrically distributed in front and back, the front side of the top block 36 located at the back side is fixedly connected with a screw rod 35, and the inner side of the front side top block 36 movably sleeves the outer side of the screw rod 35, and the front side of the top block 36 located at the front side is rotatably connected with a threaded seat 37, and the inner side of the threaded seat 37 is threadedly connected with the outer side of the screw rod 35.
[0031] It should be noted that the shape of the side close to each other of the top block 36 is a right trapezoid, and the lower surface of the inner side of the clamping plate 31 is a mountain shape, and the threaded seat 37 is rotated, so that the two top blocks 36 are close to each other, so that the spring 34 is compressed, and the cable is clamped.
[0032] As shown in Figure 3 , the lower side of the clamping plate 32 is fixedly connected with a rubber pad.
[0033] It should be noted that the rubber pad is used to avoid direct contact between the clamping plate 32 and the cable, causing wear of the cable.
[0034] As shown in Figure 3 , the front and back sides of the clamping plate 31 are fixedly connected with two clamping strips 38 symmetrically distributed in front and back, and the outer sides of the clamping strips 38 are slidably connected in the clamping grooves formed in the middle of the inner sides of the front and back sides of the mechanism column 1.
[0035] It should be noted that the clamping strip 38 is used to stabilize the clamping plate 31 and the mechanism column 1, and avoid relative movement between the clamping plate 31 and the mechanism column 1 in the left and right directions.
[0036] As shown in Figure 5 , the tensioning mechanism 5 includes a support frame 51, the inner side of the support frame 51 is fixedly connected to the front and back sides of the mechanism column 1, the inner side of the support frame 51 is rotatably connected with two guide wheels 52 symmetrically distributed on the left and right sides near the left and right sides, the inner side of the support frame 51 is slidably connected with two tensioning wheels 53 distributed on the left and right sides near the upper side, the front and back sides of the mechanism column 1 are rotatably connected with four second winding wheels 54 distributed in a rectangle near the bottom, the inner side of the mechanism column 1 is fixedly connected with a motor 56 near the bottom, the output end of the motor 56 is fixedly connected with a third gear 55, the inner side of the four second winding wheels 54 is fixedly connected with a fourth gear 57 on the side away from each other, and the upper end of the second traction rope 58 is fixedly connected with the front and back sides of the tensioning wheel 53.
[0037] It should be noted that the motor 56 drives the third gear 55 to rotate, the third gear 55 is engaged with the fourth gear 57, so that the fourth gear 57 drives the second winding wheel 54 to rotate, so that the second traction rope 58 is retracted or extended on the second winding wheel 54, thereby making the second traction rope 58 pull the tensioner 53 to move left and right, avoiding the first traction rope 45 and the cable due to thermal expansion and contraction, causing the tension of the first traction rope 45 to change, causing the cable to sag or be too tight.
[0038] As shown in Figure 5 The inner side of the two guide wheels 52 is fixedly connected with a pressure sensor.
[0039] It should be noted that the guide wheels 52 are distributed on the left and right sides, and the pressure sensor is located on the lower guide wheel 52, and the first traction rope 45 is located between the two guide wheels 52, when the cable is sagging, the lower guide wheel 52 will be subjected to greater pressure, and when it is tight, the lower guide wheel 52 will be subjected to smaller pressure.
[0040] The utility model discloses a working principle: first, fixed pulley 46 is distributed two before and after, and the front and rear two sides rotation of fixed pulley 46 are connected in the upper end inside of clamping plate 31, first gear 41 and second gear 43 are engaged together between the connection, rotate first gear 41, and then make second gear 43 drive first winding wheel 42 rotate, and then make first traction rope 45 be collected or stretch out on first winding wheel 42, and the clamp 47 is used for fixing on the cable, and the cable is erected by the first traction rope 45 to pull the cable, avoids the cable to droop and leads to the cable to sway in windy weather, and the motor 56 drives third gear 55 to rotate, and the meshing between third gear 55 and fourth gear 57 makes fourth gear 57 drive second winding wheel 54 to rotate, and the second traction rope 58 is collected or stretched out on second winding wheel 54, and then make the second traction rope 58 pull the tension pulley 53 and move left and right, avoid the first traction rope 45 and the cable because heat expansion and cold contraction lead to the tension of first traction rope 45 change, cause the cable to droop or be too tight, and the guide wheel 52 is distributed two left and right each, and the pressure sensor is located on the lower guide wheel 52, and the first traction rope 45 is located between two guide wheels 52, when the cable droops, the lower guide wheel 52 will receive greater pressure, and when tight, the lower guide wheel 52 will receive smaller pressure, by rotating first gear 41, make the first traction rope 45 erect the cable, rely on the motor 56 and drive the tension pulley 53 and move left and right, and then control the tightness on the first traction rope 45, rely on the automatic regulation mode and make the first traction rope 45 more stable to the cable fixed, response fast, convenient operation, avoid the tightness too big or too small to influence the fixed effect of cable, finally, when clamping plate 31 is inserted into the inside of mechanism column 1, the cable is placed between the inside of mechanism column 1 and clamp plate 32, the spring 34 pushes the limiting rod 33, make clamp plate 32 can fix the cable of relatively thick and relatively thin, and the top block 36 is mutually close one side shape and presents right angle trapezoid, and the inside lower surface of clamping plate 31 presents mountain shape, and the threaded seat 37 is rotated, and make two top blocks 36 mutually close, cause the spring 34 to be compressed, make the cable be clamped, by directly inserting clamping plate 31 into the inside of mechanism column 1, then rotate threaded seat 37, make the inside of mechanism column 1 and clamp plate 32 between the cable fixed, rely on the cooperation of spring 34 and top block 36, and then make the cable of different thicknesses have a better fixed effect, and the adaptability is strong.
