[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The cable traction device for substation construction is provided with an adjustment structure. When the slider drives the rotating frame to move left and right, it guides the two driven rods to slide on the outside, so that the driven rods drive the rotating frames on both sides of the slide rail to rotate on the top of the fixed plate. In this way, the three support components are distributed in a triangular shape. At this time, the rotating frame drives the pulley to rotate, so that the support components on both sides of the slide rail face the components in the middle. In this process, the cables inside the three support components will move from the inside of the device to the outside at a certain arc.

[0017] Furthermore, a moving plate is provided, and the downward movement of the moving plate pushes the clamping block to move downward synchronously, thereby forming a clamp consisting of three supporting components consisting of a clamping block, a rotating frame and a pulley. When the cable is placed inside the supporting component, the clamping block moves further downward until it fits tightly with the top of the cable. During this process, the clamping block applies pressure to the cable to firmly fix it between the clamping block and the supporting component. At this time, the moving device can pull the cable;

[0018] Furthermore, when the cable moves inside the device, it must first pass between the top of the support wheel and the two concave wheels. The two concave wheels will moderately constrain the shape of the cable when it enters the device, making it easier for the cable to enter the device smoothly. At the same time, the vibration of the cable itself is suppressed to prevent the cable vibration from causing damage to the internal parts of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In a further preferred embodiment of the present invention, Figure 1 - Figure 2 As shown, two universal wheels 2 and two fixed wheels 3 are each provided, and the two universal wheels 2 and the fixed wheels 3 are symmetrically fixedly connected to the bottom of the support plate 1; an adjusting structure is provided on the top of the support plate 1, and the adjusting structure is provided with a fixed disk 7, and the top of the fixed disk 7 is rotatably connected to a rotating frame 8, and the top of the rotating frame 8 is rotatably connected to three pulleys 9 distributed in an annular shape, and the rotating frame 8 and the pulley 9 form a supporting assembly, and the adjusting structure also includes a slide rail 10 fixedly connected to the top of the support plate 1, and a screw rod 11 is rotatably connected inside the slide rail 10, and a slider 12 is threadedly connected to the outer side of the screw rod 11, the top of the slider 12 is fixedly connected to the fixed disk 7, and the outer side of the fixed disk 7 at the top of the slider 12 is slidably connected to two driven rods 13; a positioning structure for fixing the cable is provided on one side of the top of the support plate 1, and two fixed disks 7 are provided, and two screw sleeves 17 are symmetrically distributed on both sides of the slide rail 10, and the end of the driven rod 13 away from the slider 12 is fixedly connected to the fixed disk 7, and the slider 12 is slidably connected to the inside of the slide rail 10;

[0028] When the cable is placed on the top of the support assembly formed by the rotating frame 8 and the pulley 9, the cable will be supported by the three support assemblies. At this time, the rotating adjustment shaft 18 drives the transmission shaft 19 to rotate, so that the transmission shaft 19 drives the screw rod 11 to rotate through the bevel gear. At this time, the slider 12 is driven by the screw rod 11 to slide inside the slide rail 10, and then the slider 12 drives the rotating frame 8 on its top to move left and right. When the slider 12 drives the rotating frame 8 to move left and right, it will guide the two driven rods 13 to slide on the outside, so that the driven rods 13 drive the rotating frames 8 on both sides of the slide rail 10 to rotate on the top of the fixed disk 7. In this way, the three support assemblies are distributed in a triangular shape. At this time, the rotating frame 8 will drive the pulley 9 to rotate, so that the support assemblies located on both sides of the slide rail 10 face the middle assembly. In this process, the cables located inside the three support assemblies will move from the inside of the device to the outside with a certain arc.

[0029] In a further preferred embodiment of the present invention, Figure 3 - Figure 4As shown, the positioning structure is provided with a support frame 14, and a moving plate 15 is slidably connected inside the support frame 14, two symmetrically distributed clamping blocks 16 are fixedly connected to the bottom of the moving plate 15, and two symmetrically distributed screw sleeves 17 are fixedly connected to the side of the bottom of the moving plate 15 away from the clamping blocks 16, and the clamping blocks 16 are distributed between the three supporting components formed by the rotating frame 8 and the pulley 9, and the clamping blocks 16 and the three supporting components formed by the rotating frame 8 and the pulley 9 form a fixture;

[0030] First, rotate the adjustment shaft 18 to drive the transmission shaft 19 to rotate, so that the transmission shaft 19 drives the two screws 21 to rotate simultaneously through the bevel gear. At this time, the screw 21 will rotate inside the screw sleeve 17. At this time, the screw 21 will drive the screw sleeve 17 to move downward through the threaded connection between the screw sleeve 17 and the screw 21, so that the screw sleeve 17 drives the moving plate 15 to move vertically inside the support frame 14. The downward movement of the moving plate 15 pushes the clamping block 16 to move downward synchronously, thereby forming a clamp composed of three support components consisting of the clamping block 16, the rotating frame 8 and the pulley 9. When the cable is placed inside the support component, the clamping block 16 is further moved downward until it is tightly fitted with the top of the cable. During this process, the clamping block 16 applies pressure to the cable to firmly fix it between the clamping block 16 and the support component. At this time, the moving device can pull the cable.

[0032] When the cable moves inside the device, it must first pass between the top of the support wheel 6 and the two concave wheels 5. The two concave wheels 5 moderately constrain the shape of the cable when it enters the device, making it easier for the cable to enter the device smoothly. At the same time, the vibration of the cable itself is suppressed to prevent the cable vibration from causing damage to the internal parts of the device.
