Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage line tighteners, in particular to a high-voltage line construction tightener. Background Art

[0002] A wire tensioner, also known as a ratchet tensioner, is used to tighten conductors during overhead line installation. To use it, first loosen the wire rope or galvanized iron wire from the tensioner and secure it to the crossarm. Clamp the conductor with wire clamps and then use a special wrench. The ratchet acts as a counter-rotation mechanism, gradually winding the wire rope or galvanized iron wire around the ratchet drum, tightening the conductor.

[0003] However, when a conventional high-voltage line construction tensioner is put into use, a worker needs to manually operate the tensioner with a wrench to tighten the wire. However, the wrenches of most tensioners are long, which can reduce the worker's workload. When the working environment is relatively narrow, the long wrench cannot reach the working position, so the worker needs to replace the tensioner to work. This not only requires the worker to carry multiple tensioners at the same time, but also increases the worker's workload.

[0004] At the same time, most high-voltage line construction tensioners need to be stored and transported to the construction site by workers. However, due to the long wrench, the tensioner occupies a large space and it is extremely inconvenient for workers to transport the tensioner, thereby reducing the practicality of the tensioner.

[0021] The following will be combined with the drawings in 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.

[0022] See also Figure 1-4The yoke 3 is provided with a hook assembly 4 on one side of the support plate 1, and a hook assembly 4 is provided on the other side of the support plate 1. The hook assembly 4 can control the clamp and, under the action of the wire rope 3, enable the hook assembly 4 to tighten the high-voltage line. A rotating block 5 is rotatably connected to one side of the support plate 1, and a fixed block 6 is bolted to one side of the rotating block 5. A clamping mechanism 7 is provided on one side of the fixed block 6. A mounting shell 8 is provided on one side of the support plate 1. Under the action of the clamping mechanism 7, the mounting shell 8 can be fixed to one side of the rotating block 5, so that the staff can disassemble the mounting shell 8, which is convenient for the staff to store and transport the tensioner, which not only reduces the labor of the staff, but also increases the practicality of the tensioner. The cam 11 is connected to the inner cavity of the connecting shell 9 so that the cam 11 can be used in different environments, thereby increasing the practicality of the cam 11. A slider 11 is bolted to one side of the sliding shell 10. The surface of the slider 11 is slidably connected to the inner cavity of the connecting shell 9, thereby preventing the sliding shell 10 from being separated from the inner cavity of the connecting shell 9. A handle 12 is bolted to one side of the sliding shell 10. The handle 12 is a hollow design. Under the action of the handle 12, it is convenient for the staff to pull out the connecting shell 9, reducing the labor of the staff. A hand turntable 13 is provided on one side of the connecting shell 9. The surface of the hand turntable 13 is a recessed design. A limiting mechanism 14 is provided on one side of the hand turntable 13. With the cooperation of the hand turntable 13 and the limiting mechanism 14, the sliding shell 10 can be fixed inside the connecting shell 9, so that the cam 11 can work in different working environments, thereby increasing the practicality of the cam 11.

[0023] When the locking cam 73 is in the unlocking state, the locking cam 73 is locked and the locking cam 73 is in the unlocking state, so that the locking cam 73 can be unlocked and the winch cam 73 can be unlocked, thereby locking the cam 73 in the unlocking state.

[0024] The limiting mechanism 14 includes a moving rod 141, one side of the moving rod 141 is fixedly connected to one side of the hand turntable 13, and one side of the moving rod 141 is slidably connected to one side of the connecting shell 9. A tension spring 142 is fixed to one side of the hand turntable 13, and one side of the tension spring 142 is fixedly connected to one side of the connecting shell 9. A corresponding hole 143 is opened on one side of the sliding shell 10, and the inner wall of the corresponding hole 143 is slidably connected to the surface of the moving rod 141. With the cooperation of the hand turntable 13 and the moving rod 141, the tension spring 142 can be stretched, so that the moving rod 141 can be moved out of the corresponding hole 143. Then the staff uses the handle 12 to move the sliding shell 10 in the inner cavity of the connecting shell 9, so that the tensioner can work in different working environments, effectively preventing the situation where the connecting shell 9 is too long and cannot work inside the environment, thereby increasing the practicality of the tensioner.

[0025] Working principle: First, the staff transports the tensioner to the location where construction is required. Under the action of the installation shell 8 and the connecting rod 73, the guide block 72 can drive the sliding rod 71 to move upward in the inner cavity of the fixed block 6, so that the sliding rod 71 can move to the inner cavity of the installation shell 8, so that the installation shell 8 can be fixed on one side of the rotating block 5, so that the connecting shell 9 can drive the rotating block 5 to rotate through the installation shell 8. When the construction environment is relatively narrow, the staff drives the moving rod 141 to move through the hand turntable 13, and at the same time stretches the tension spring 142. Under the cooperation of the sliding shell 10 and the slider 11, the sliding shell 10 can be moved inside the connecting shell 9 so that the corresponding hole 143 can correspond to the moving rod 141. Under the action of the rebound of the tension spring 142, the moving rod 141 can be moved to the inside of the corresponding hole 143, so that the tensioner can work in a narrow environment. Then the staff tightens the high-voltage wire through the take-up assembly 2, the wire rope 3 and the hook assembly 4. When the staff completes the construction, the tensioner can be stored.
