Problems solved by technology
In the past, insulator strings on transmission lines were often suspended by UB hanging boards (such as figure 1 As shown), there is only one single-hanging connection between the UB hanging board and the connecting board. Once the single-hanging connection breaks, a disconnection accident will occur, endangering personal and equipment safety

Embodiment
[0016] image 3 It is a structural schematic diagram of an embodiment of the present invention; Figure 4 yes image 3 The left view of the left side view; an improved double-string insulator UB hanging plate suspension device of the present invention, including U-shaped channel steel 10, UB hanging plate 1, hanging screw 3, four-hole connecting plate 11, is characterized in that: the U with the mouth facing downward There are three holes on both sides of the U-shaped channel steel 10, and the two holes on the upper part of each side are UB hanging plate connecting holes, which are connected with the UB hanging plate 1 through two UB hanging plate hanging screws 3, and there is one on each side of the U-shaped channel steel. The fixing hole is used to pass the fixing screw 12. The U-shaped channel steel with the mouth facing down is buckled on two back-to-back angle irons 2. The steel is fixed on two back-to-back angle irons 2 by fixing screws 12; there are upper and lower r...

An improved double-string insulator UB hanging plate suspension device comprises U-shaped channel steel, UB hanging plates, suspension screws and a four-hole yoke plate. The improved double-string insulator UB hanging plate suspension device is characterized in that three holes are arranged in each of the two sides of the U-shaped channel steel with downward openings, the two holes in the upper part of each side are UB hanging plate connecting holes which are connected with the UB hanging plates through the two UB hanging plate suspension screws, one fixing hole is arranged in each side of theU-shaped channel steel and used for fixing screws to pass through, the U-shaped channel steel with the downward openings is buckled onto two pieces of back-to-back angle iron, bottom edges of the twosides of the U-shaped channel steel are in contact with the angle iron to bear the force, and the U-shaped channel steel are fixed by the fixing screws on the two pieces of back-to-back angle iron; and the four-hole yoke plate has two rows of holes in the top and bottom, the top row has two top holes which are connected with the UB hanging plates through U-shaped hanging rings, and the four-holeyoke plate are connected with two insulators. The beneficial effects are that the single UB hanging plate suspension in the past is changed into the two UB hanging plate suspension and the safety andreliability are improved.
Description
technical field [0001] The invention relates to a transmission line insulator suspension device, in particular to an improved double-string insulator UB hanging board suspension device. Background technique [0002] With the improvement of power supply reliability, transmission lines cross sections such as high-speed railways, expressways, and important passages, and the linear towers with single suspension points for conductor suspension need to be transformed into double suspension points to improve the operation of transmission lines across high-speed railways, expressways, etc. Safety. In the past, insulator strings on transmission lines were often suspended by UB hanging boards (such as figure 1 As shown), there is only one single-hanging connection between the UB hanging board and the connecting board. Once the single-hanging connection breaks, a disconnection accident will occur, endangering personal and equipment safety. Contents of the invention [0003] The pur...
