Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a power installation tensioning device. Background Technology

[0002] When constructing new overhead power lines, the power lines need to be pulled from one end of the pole to the other and tightened to ensure that the power lines reach the designed tension and sag. This ensures that the power lines will not be pulled too low and will not have insufficient safe distance from the ground or other objects, and will not drag and wear on the ground during the pulling process, thus protecting the power lines.

[0003] Currently, most wire tensioning equipment connects a hook at one end to a wire puller to move the wire and tighten it. The hook at the other end hooks onto a fixing device, which is mounted on a pole. Since both hooks are movably connected to the tensioning equipment, the equipment is prone to shaking during use, requiring operators to hold it by hand. This instability affects the effectiveness of the equipment. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] Reference Figures 1-4This utility model provides a technical solution: a power installation tensioning device, including an installation frame 1, a stabilizing mechanism 3, and a secondary stabilizing mechanism 4. An inverted U-shaped plate 2 is installed at the upper inner side of the installation frame 1. The stabilizing mechanism 3 includes a bent rod 31, which is installed on the inverted U-shaped plate 2. A connecting plate 311 is installed at the top of the bent rod 31. A vertical plate 32 is installed at a position corresponding to the connecting plate 311. A screw 33 is threaded inside the vertical plate 32 and the connecting plate 311. The secondary stabilizing mechanism 4 is installed on the inverted U-shaped plate 2 to improve the connection stability of the device and facilitate the control of the device to stabilize and tighten the wires.

[0031] In a preferred embodiment, the secondary stabilizing mechanism 4 includes a circular plate 41, a threaded hole 42, and a positioning bolt 43. The circular plate 41 is stably installed at the bottom end of the bent rod 31 and positioned above the bent rod 31. The bent rod 31 is rotatably connected to the inverted U-shaped plate 2. The outer surface of the circular plate 41 has several circular holes 5, and the upper surface of the inverted U-shaped plate 2 has a threaded hole 42. The diameter of the threaded hole 42 matches the diameter of the circular holes 5. The positioning bolt 43 is inserted into the interior of the circular holes 5 and threadedly connected to the threaded hole 42. The upper surface of the circular plate 41 has a sliding groove 6, and a slider 7 is provided inside the sliding groove 6. The vertical plate 32 is stably installed on the top of the slider 7, and the vertical plate 32 also corresponds to the position of the bent rod 31.

[0032] In actual use, in order to improve the stability of the equipment connection end, after the curved rod 31 and the vertical plate 32 are stably clamped, the circular plate 41 can be positioned. The positioning bolt 43 is passed through the inside of the circular plate 41 and screwed into the inside of the inverted U-shaped plate 2 to position the curved rod 31 so that it will not rotate at will, thereby positioning the connection end of the equipment. There will be no shaking during the wire tightening process, thus improving the use effect.

[0033] By stably installing a curved rod 31 at one end of the inner side of the mounting frame 1, and rotatably installing a connecting rod 8 on the mounting frame 1, with a driving component 9 installed on the connecting rod 8, the device tightens the wire by controlling the movement of the hook 14 and pulling the wire toward the position of the mounting frame 1. To facilitate the winding of the pulled-out rope 13, the connecting rod 8 is rotatably installed at the inner side of the mounting frame 1, and a winding roller 10 is rotatably installed at the inner side of the mounting frame 1. A driven component 11 is installed on the winding roller 10, and a rectangular block 12 is stably installed at the inner side of the mounting frame 1. The rope 13 is wound on the winding roller 10, and one end of the rope 13 is connected to the hook 14 to hook the wire and tighten the wire.

[0034] With the above structure, the rotation of the control linkage 8 will drive the drive component 9 to rotate. The drive component 9 includes a first gear, and the driven component 11 includes a second gear. The second gears are meshed together. Therefore, when the linkage 8 rotates, the drive component 9 and the driven component 11 mesh together, driving the take-up roller 10 to rotate, thereby winding up the rope 13. During the winding process, the rope 13 will pass through the inside of the rectangular block 12, which can limit the rope 13, avoid tangling, ensure the normal winding of the rope 13, and pull the hook 14 to move towards the position of the mounting frame 1 to tighten the wire.

[0035] One end of the connecting rod 8 is extended to the outside of the mounting frame 1, and a ratchet 15 is installed on the connecting rod 8. A drive rod 16 is also installed at the outer end of the connecting rod 8. Most wire tensioning equipment is operated from the position where the wire is installed on the pole, and the general operation is mostly done manually by the staff. Therefore, a drive rod 16 is set outside the mounting frame 1. The repeated rotation of the drive rod 16 can control the rotation of the connecting rod 8, thereby driving the winding roller 10 to rotate, which is convenient for operation.

[0036] Specifically, the working process or working principle of a power installation tensioning device is as follows: Currently, most devices for tensioning power lines connect a hook 14 at one end to a power line puller to pull the power line and achieve tensioning. The hook 14 at the other end hooks onto a fixing component, which is a mounting bracket on a power pole. Since both hooks 14 are movably connected to the tensioning device, the device is prone to shaking during use, requiring operators to manually support it, resulting in unstable operation and affecting the effectiveness of use. Therefore, this device was designed to solve this problem.

[0037] This device can securely connect the equipment's connection end to external connectors, thereby facilitating equipment operation and wire tightening. Specifically, since external connectors have pre-drilled holes, before using this device, the bent rod 31 can be passed through the hole, and the vertical plate 32 can be placed on the outside of the connector. Then, the vertical plate 32 is moved so that one side of the vertical plate 32 fits against the outer surface of the connector. Subsequently, the screw 33 is screwed into the inside of the vertical plate 32, passes through the inside of the vertical plate 32, and then is screwed into the inside of the connecting plate 311. Under the action of the screw 33, the vertical plate 32 and the bent rod 31 can be stably clamped on the connector.

[0038] To further improve the stability of the device during use, after positioning the connection end of the device, the circular plate 41 can be positioned. The circular plate 41 is provided with several circular holes 5, and several threaded holes 42 are provided on the outer surface of the inverted U-shaped plate 2. The number of threaded holes 42 corresponds to the number of circular holes 5, and the diameter is also the same. By passing the positioning bolt 43 through the inside of the circular hole 5 and screwing it into the corresponding threaded hole 42, the circular plate 41 can be positioned, so that the connection end of the device will not rotate.

[0039] Pull the hook 14 towards the outside of the mounting frame 1. During the pulling process, the rope 13 on the take-up roller 10 will be released, hooking the hook 14 onto the wire that needs to be tightened. Then, a worker repeatedly rotates the drive rod 16. The rotation of the drive rod 16 will drive the connecting rod 8 to rotate, and the rotation of the connecting rod 8 will drive the drive component 9 to rotate. The drive component 9 includes a first gear, and the corresponding driven component 11 includes a second gear. The first gear and the second gear are meshed and connected. When the drive component 9 rotates, it drives the driven component 11 to rotate, thereby controlling the take-up roller 10 to wind up the rope 13 and pull the hook 14 towards the position of the mounting frame 1. At the same time, the wire is pulled to move. As the hook 14 gets closer to the position of the mounting frame 1, the wire is tightened.

[0040] The principle behind the use of the drive rod 16 and ratchet 15 in the device is to convert manual force into tightening force using a lever. Specifically, the drive rod 16 acts as a lever; when the drive rod 16 rotates, the longer lever arm generates a greater pulling force, tightening the wire. The rotation of the drive rod 16 drives the drive component 9 to rotate and indirectly drives the driven component 11 to rotate, pulling the rope 13 to move and adjusting the wire tension. The drive rod 16 achieves unidirectional movement through the ratchet 15 and pawl. Each push of the drive rod 16 tightens the device by a certain amount, preventing the wire from loosening. To prevent the ratchet 15 from rotating back during the tightening process, the edge of the ratchet 15 has unidirectionally inclined teeth, and the pawl (a spring-loaded metal piece) is engaged between the teeth. When the drive rod 16 is pushed in the tightening direction, the pawl rotates with the ratchet 15 and is released; when it retracts in the opposite direction, the pawl engages with the next tooth, preventing the ratchet 15 from rotating back.

[0041] The specific tensioning method in this device is the same as the working principle of existing tensioning equipment, so it will not be described in detail here.
