Problems solved by technology

[0002] The tower cable and the center ring of the semi-air conditioner are worn. Due to the shaking of the cable hanging from the top of the tower to the saddle bridge, the cable and the self-aligning ring are collided and worn for a long time, which may wear out the cable protective layer; on the other hand, the self-aligning ring It is a conductive metal. After the protective layer of the tower cable is worn out, the cable will be directly short-circuited to the ground, causing discharge to the ground, affecting the stable operation of the unit, causing damage to electrical components, and safety accidents may occur
Winding friction problem at the U-shaped bend of the saddle bridge. When the unit continues to yaw against the wind in a certain direction, the cables may be entangled together, causing friction between each other, and the cable insulation layer will be damaged after a long time

Embodiment 1

[0020] An anti-abrasion fixing device for tower cables, which consists of a spacer ring device fixed at the U-shaped bend of the saddle bridge to prevent cable entanglement and an anti-abrasion device fixed at the semi-air core ring to prevent cable abrasion;

[0021] The anti-wear device includes an outer ring 3 and an inner liner 1, and the inner liner and the outer ring are fixed by bolts 7; a threaded hole 4 is provided on the annular surface of the outer ring, so that the outer ring and the inner liner The plates are secured by bolts.

[0022] The spacer device is a circular ring plate 8, a plurality of evenly arranged outer semicircular grooves 9 are opened on the outer annular surface of the described annular plate, and a plurality of evenly arranged inner semicircular grooves are opened on the inner annular surface 10.

Embodiment 2

[0024] According to the anti-friction fixing device for tower cables in Embodiment 1, the outer semicircular groove of the circular ring plate and the inner semicircular groove are misaligned.

Embodiment 3

[0026] According to the anti-friction fixing device for the tower cable in the embodiment 1 or 2, the outer ring is formed by buckling two semi-circular rings 5 ​​and fixing them with bolts.

[0027] There are multiple V-shaped grooves on the outer ring surface of the inner liner, and the V-shaped grooves and the outer ring form multiple inner cavities for cable clamping, and the cables 6 are separated and fixed in groups of three to prevent them from being locked. Cable wear and wear in series with each other.

Abstract

The invention discloses a tower drum cable anti-abrasion fixing device. A cable from the top end of a tower drum to a saddle bridge part shakes, so that the cable and a self-aligning ring are collided and abraded for a long time, and a cable protection layer is possibly abraded. The device comprises a spacer ring device which is fixed at a U-shaped bend of a saddle bridge and is used for preventing a cable from being wound, and an anti-wear device which is fixed at a semi-air-conditioning core ring and is used for preventing the cable from being worn, the anti-abrasion device comprises an outer lantern ring (3) and an inner lining plate (1), and the inner lining plate and the outer lantern ring are fixed through a bolt (7); the spacer ring device is an annular plate (8), a plurality of evenly-arranged outer semicircular grooves (9) are formed in the outer annular face of the annular plate, and a plurality of evenly-arranged inner semicircular grooves (10) are formed in the inner annular face of the annular plate. The anti-abrasion fixing device is used for anti-abrasion fixing of the tower drum cable.

Description

technical field [0001] The invention relates to an anti-wear fixing device for tower tube cables. Background technique [0002] The tower cable and the center ring of the semi-air conditioner are worn. Due to the shaking of the cable hanging from the top of the tower to the saddle bridge, the cable and the self-aligning ring are collided and worn for a long time, which may wear out the cable protective layer; on the other hand, the self-aligning ring It is a conductive metal. After the protective layer of the tower cable is worn out, the cable will be directly shorted to the ground, causing discharge to the ground, affecting the stable operation of the unit, causing damage to electrical components, and safety accidents may occur. The winding friction problem at the U-shaped bend of the saddle bridge. When the unit continues to yaw against the wind in a certain direction, the cables may be entangled together, causing friction between each other, and the cable insulation layer...
