Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution line clamps, in particular to a straight-line double-top clamp for easy installation. BACKGROUND

[0002] A power distribution line clamp is a metal clamp used for erecting and fixing power distribution lines, usually made of cast iron and steel plates, in the shape of a semicircle or a full circle, closed and fastened by connecting pieces such as bolts, which can firmly fix crossarms, insulators and cables on the power pole.

[0003] With the continuous improvement of safety and stability and installation adaptability in the construction of power distribution lines, the traditional straight-line single-top clamp is only connected to the power pole, crossarm and other components through a single contact point or a small contact area, which is prone to loose fixation or component deformation due to stress concentration when facing large-span lines, heavy equipment or complex weather conditions, and therefore a straight-line double-top clamp is needed.

[0004] The straight-line double-top clamp on the market is mainly composed of clamp pieces, connecting bolts and support frames, which can provide support to the equipment to be installed by closing and fixing the two clamp pieces on the power pole through the connecting bolts and the support frames on both sides. However, the double-top clamp needs to be used outdoors for a long time and is eroded by rainwater and humid air, especially at the close contact with the power pole or the fixed equipment, which may cause corrosion, weaken the structural strength of the clamp and shorten its service life. To solve the above problems, the existing technology uses hot-dip galvanizing to form a dense zinc layer on the surface of the clamp to isolate air and moisture, thereby reducing the corrosion of the clamp. However, when the device is in use, the straight-line double-top clamp is composed of upper and lower semicircular clamp pieces, the end is bent to form an installation ear, and under the action of line tension, wind force and its own gravity for a long time, the connection between the clamp piece and the installation ear is prone to deformation and fracture. To solve the above problem, the existing technology adds a triangular or trapezoidal reinforcing plate at the connection between the clamp piece and the installation ear to improve the overall tensile and compressive strength of the clamp. However, in actual use, the device fixes the upper and lower clamps by bolts and nuts, which are prone to loosening and falling due to temperature changes and vibration factors in long-term outdoor environment, causing the upper and lower clamps to fall off, reducing the practicality of the device and failing to meet the needs of users.
