Description

A fixing device for an anti-vibration hammer of a power transmission line

technical field

The invention relates to a fixing device, in particular to a fixing device for an anti-vibration hammer of a power transmission line.

Background technique

On the ultra-high voltage AC-DC transmission line, the guide and ground wires are erected between two erected towers. When the wire is subjected to wind force, it will vibrate. In order to reduce the vibration of the wire due to the wind force, an anti-vibration hammer is installed. However, the anti-vibration hammer installed on the guide and the ground often slips and falls off, and the staff needs to climb up to deal with it, and it is troublesome to adjust the position of the anti-vibration hammer.

Chinese patent CN203632165U discloses an operating rod type anti-vibration hammer fixing device, the upper semicircle pinch plate (1) and the lower semicircle pinch plate (3) are buckled on the wire, and the lower part of the lower semicircle pinch plate (3) is provided with an internal thread pipe (4), the external thread on the upper part of the operating rod (7) is connected to the internal thread of the internally threaded pipe (4), and the upper end of the operating rod (7) passes through the lower semicircular pinch plate (3) and pushes against the wire, and the operating rod ( The lower end of 7) is connected to the middle part of the connecting rod (9), and the two ends of the spring (8) provided on the outer edge of the lower part of the operating rod (7) push against the lower end of the internally threaded tube (4) and the upper part of the connecting rod (9). The two ends of the connecting rod (9) are respectively provided with an anti-vibration hammer (6); the present invention uses the upper end of the operating rod in the inner threaded pipe to lock the wires, effectively preventing the displacement of the anti-vibration hammer. However, the operating rod of this patent is in contact with the wire, and the operating rod is easy to loose as the wire shakes, and the position of the anti-vibration hammer will slip, and the upper semicircle pinch plate and the lower semicircle pinch plate need to be fixed on the wire by bolts. kind of hard.

Chinese patent CN204706856U discloses a device for preventing the anti-vibration hammer from slipping on overhead power transmission lines, which includes two hinged clamp arms, one of which is provided with nut clamping holes, and the other clamp arm is provided with bolt clamping holes. The handles of the pliers arms are connected by an elastic mechanism, and the elastic mechanism includes bolts passing through the handles, and springs sleeved on the bolts and located between the handles. The installation method of the traditional anti-vibration hammer is not changed, the holding force of the anti-vibration hammer is increased, the axial movement of the anti-vibration hammer is prevented, the problem of slipping and falling off of the anti-vibration hammer is solved at one time, and the slipping and falling of the anti-vibration hammer is avoided. In the section where shedding occurs frequently, the phenomenon of anti-vibration hammer slip-recovery-re-slip-recovery effectively avoids the wear of the ground wire. However, the anti-vibration hammer anti-slip device in this patent only acts on the anti-vibration hammer nut, and does not fix the anti-vibration hammer clamp, which cannot solve the anti-vibration hammer loosening caused by wind vibration, and the anti-vibration hammer is still easy to slip .

The fixing device of the transmission line anti-vibration hammer of the present invention passes through the hook The sliding of the anti-vibration hammer line clamp on the electric wire is prevented, and the cooperation of the fixed hook and the fixing part of the anti-vibration hammer line clamp secures the position of the anti-vibration hammer and prevents the anti-vibration hammer from falling off.

2. The cylindrical support rod of the present invention is hollow, which reduces the weight of the fixing device. The operating handle is pistol-shaped, which reduces the weight of the fixture. A first through hole is opened on both sides of the operating handle, and the cylindrical support rod passes through the first through hole. The operating handle can rotate around the cylindrical supporting rod, and at the same time, the connecting seat drives the fixed hook around the connection on the operating handle. Rotate the column and adjust the fixing hook to the proper position. A second through hole is opened on the connecting seat, and the connecting column passes through the second through hole. After the fixing hook is fixed, the operating handle is rotated downward around the connecting column to further fix the position of the hook and the fixing hook firmly. A fixing ring is arranged on the cylindrical support rod and located on both sides of the handle respectively, so that the position of the handle is aligned with the clamp of the anti-vibration hammer, so as to prevent the handle from sliding on the cylindrical support rod and facilitate fixing. A limit ring matching the anti-vibration hammer nut is arranged on the upper edge of the fixing hook, and the fixing of the operating handle is more firm.
