Description

Technical Field

[0001] This utility model relates to the field of power safety technology, specifically to a power insulator fixing device adapted to an angle steel crossarm. Background Technology

[0002] In power distribution lines, drop-out fuses are critical overload and short-circuit protection devices, typically installed on iron crossarms via porcelain insulators. A typical installation structure involves a pre-drilled mounting hole in the center of the porcelain insulator. One end of a metal connector is fixed into the hole using cement adhesive, while the other end is rigidly connected to the crossarm. While this cement-based bonding process provides sufficient mechanical strength initially, during long-term outdoor operation, factors such as temperature cycling, rain erosion, mechanical vibration, and material aging can cause the cement adhesive to crack, powder, or even fail. This reduces the bond strength between the connector and the insulator, leading to loosening of the porcelain insulator. If this hidden danger is not detected and addressed promptly, it can cause electrical accidents such as equipment tilting, lead wire breakage, or even insulator detachment, seriously threatening the safe and stable operation of the line.

[0003] Therefore, during regular inspections of power lines, if loose porcelain insulators are detected, rapid and effective temporary reinforcement measures must be taken. However, existing devices for securing loose porcelain insulators require workers to climb to a high position to hook the loose insulator with the hook mechanism of the fixing device, and then fix the fixing device to the angle steel crossarm with bolts and nuts, resulting in low installation efficiency. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this utility model provides a power insulator fixing device adapted to angle steel crossarms, which can be quickly fixed onto angle steel crossarms.

[0005] This utility model discloses a power insulator fixing device adapted to angle steel crossarms, including a base and a hook holding mechanism disposed on the base. The lower side of the base is provided with a linker insertion hole, and the rear side of the base is provided with a first slot for fixing the angle steel. A locking arm is hinged to the upper side of the base at the opening of the first slot. The locking arm is horizontally disposed, and a first torsion spring is provided at the hinge point between the locking arm and the base to make the locking arm have a downward pressing tendency. A locking mechanism is provided between the base and the locking arm to keep the locking arm horizontal. The locking mechanism is provided with a trigger position to unlock the locking mechanism. The trigger position is located between the upper end face and the lower end face of the first slot. A fastening mechanism is provided on the lower side of the end of the locking arm away from the base.

[0006] The core principle of this utility model is that the operator fixes the link bar in the link bar insertion hole, raises the device on the ground, and inserts the horizontal side of the angle steel crossarm into the No. 1 slot on the base. During the insertion process, the upper side of the horizontal side of the angle steel crossarm presses against the trigger position of the locking mechanism to unlock it. The locking arm is pressed down under the action of the No. 1 torsion spring, so that the fastening mechanism is fastened to the lower end of the vertical side of the angle steel crossarm, achieving quick installation.

After passing through the through hole, the first rod is locked on the side of the engagement component closer to the base. The second rod passes around the side of the locking arm and is located below the second locking arm. A spring is provided between the engagement component and the locking arm to allow the engagement component to move towards the base. A third torsion spring is provided at the hinge of the locking component and the locking arm to keep the locking component in a locked state.

[0009] To accommodate angle steel crossarms of different sizes, the locking arm includes a first locking arm hinged to the base and a second locking arm that can slide horizontally on the first locking arm. The first and second locking arms are locked together by a locking structure, and a fastening mechanism is provided on the second locking arm.

According to the specifications and dimensions of the angle steel crossarm on site, the position between the first and second locking arms is adjusted, and then locked by the locking structure, so that the length of the locking arm is adapted to the size of the angle steel crossarm on site. By setting the limit component in different first positioning holes, the size of the angle steel crossarm on site can be adapted.

[0010] To better accommodate porcelain bottles at various angles and distances, a plate is vertically positioned at the center of the upper side of the base. Two first sliding grooves are provided on one side of the plate, forming different angles with the horizontal plane.
