Description

Technical Field

[0001] The utility model belongs to the technical field of power line clamps, and particularly relates to a convenient-to-install preformed suspension clamp for power lines. Background Art

[0002] The design of the preformed suspension clamp for power lines is to fix the optical cable or other electric wires to ensure their stability and safety during power transmission;

[0003] The preformed suspension clamp for power lines includes a housing, an optical cable, inner strands, outer strands and a rubber clamping block. The inner strands are wrapped on the outer surface of the optical cable, the rubber clamping block is wrapped on the outer side of the inner strands, the outer strands are wrapped on the outer sides of the rubber clamping block and the inner strands, and the housing is wrapped on the outer side of the outer strands. The housing is directly sleeved on the outer sides of the rubber clamping block and the inner strands and then connected to a right-angle hanging ring and a U-shaped hanging plate. However, the grip of the housing on the optical cable, inner strands, outer strands and rubber clamping block is average.

[0004] Insufficient grip of the housing may cause the clamp to fail to firmly fix the optical cable. The optical cable may be displaced under the action of wind or other external forces, thus affecting the stability and transmission performance of the optical cable. Long-term vibration and temperature changes may cause the aging of the rubber clamping block, thereby weakening its fixing effect on the optical cable. If the grip of the housing is insufficient, this problem may be exacerbated. Due to insufficient grip, the stability of the optical cable may become poor, which may increase the frequency of daily maintenance and inspection, as well as the possible repair cost. The housing with insufficient grip may require additional auxiliary measures to ensure the fixing of the optical cable, such as using more bolts or straps, which may increase the installation difficulty and complexity. Content of the Utility Model

[0005] The present invention aims to solve the technical problem that the grip of the housing on the optical cable, inner strands, outer strands and rubber clamping block is average in the above-mentioned prior art.

[0006] To achieve the above object, the utility model provides the following technical solution:

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The following further elaborates on this application Figures 1-4 for a more detailed description,

[0026] An embodiment of the present application discloses a convenient-to-install power preformed suspension clamp, including a housing 1, an optical cable 2, an inner stranded wire 3, an outer stranded wire 4, and a rubber clamping block 5. The housing 1 wraps around the outer sides of the optical cable 2, the inner stranded wire 3, the outer stranded wire 4, and the rubber clamping block 5;

[0027] The inner stranded wire 3 is wrapped around the outer surface of the optical cable 2. An additional protective layer is provided to reduce the risk of damage to the optical cable 2 from external forces, which helps to evenly disperse the external pressure and reduce direct damage to the optical cable 2. The rubber clamping block 5 is formed by butting two rubber blocks 502 with through slots 501, and the through slots 501 are wrapped around the outer side surface of the inner stranded wire 3. This improves the gripping force on the inner stranded wire 3 and ensures the stable fixation of the optical cable 2. The outer stranded wire 4 is wrapped around the outer side surfaces of the rubber clamping block 5 and the inner stranded wire 3, and the housing 1 is wrapped around the outer side surface of the outer stranded wire 4. It provides multi-layer protection, enhances the stability and durability of the overall structure, disperses external forces, reduces the pressure on individual components, and extends the service life of the wire clamp.

[0028] The housing 1 includes a lower housing 101 and an upper housing 102 hinged to the lower housing 101. Two first bushings 104 are fixedly connected to the lower housing 101, and two second bushings 105 are fixedly connected to the upper housing 102. The two first bushings 104 are fixedly sleeved on the outer side surface of the shaft rod 106, and the two second bushings 105 are rotatably sleeved on the outer side surface of the shaft rod 106, and the second bushings 105 are arranged staggered with the first bushings 104. This enables the upper housing 102 to rotate relative to the lower housing 101, facilitating the installation and adjustment of the position of the optical cable 2. It improves the flexibility of the wire clamp and enables it to maintain a good fixation effect at different positions.

[0029] Two arc-shaped openings 103 symmetrically arranged front and back are provided on the upper housing 102. Two U-shaped hoops 6 passing through the lower housing 101 are arranged in the two arc-shaped openings 103. The two U-shaped hoops 6 lock and position the optical cable 2, the inner stranded wire 3, the outer stranded wire 4, and the rubber clamping block 5 in the housing 1 through lock nuts 7.

[0030] Insertion cylinders 107 for the U-shaped hoops 6 to penetrate are respectively fixedly provided on both sides of the lower housing 101. The lock nuts 7 are located on the outer side surfaces of the insertion cylinders 107, and a gasket 8 is sleeved on the U-shaped hoops 6 between the lock nuts 7 and the insertion cylinders 107. This enables the U-shaped hoops 6 to be more easily inserted and fixed around the optical cable 2, simplifies the installation process, and the use of the gasket 8 can protect the optical cable 2 from the direct pressure of the U-shaped hoops 6 and reduce the risk of damage.

[0031] A U-shaped plate 9 is fixedly provided on the outer side surface at the center of the lower housing 101. Both ends of the U-shaped plate 9 are threadedly connected to a connecting plate 10 through bolts. After the connecting plate 10 is butt-connected to the U-shaped plate 9, a hanging ring sleeved on the outer side surface of the housing 1 is formed. A U-shaped hanging plate 11 is installed in the positioning hole at the center of the top of the U-shaped plate 9. It provides a stable hanging ring structure, facilitating the suspension and fixation of the wire clamp. Through bolt connection, the stability and adjustability of the structure are increased. The U-shaped hanging plate 11 facilitates the connection of the wire clamp with right-angle hanging rings and U-shaped hanging plates 11, improves the installation convenience, strengthens the hanging stability of the wire clamp, and ensures that the optical cable 2 will not fall off under various environmental conditions.

[0032] This conveniently installed preformed suspension clamp for electric power locks and positions the optical cable 2, inner stranded wire 3, outer stranded wire 4, and rubber clamping block 5 in the housing 1 through two U-shaped clamps 6, so as to enhance the gripping force of the housing 1 on the optical cable 2, inner stranded wire 3, outer stranded wire 4, and rubber clamping block 5; the two U-shaped clamps 6 are located within two arc-shaped openings 103 and are arranged through the lower housing 101. The two U-shaped clamps 6 are used to fix the optical cable 2, inner stranded wire 3, outer stranded wire 4, and rubber clamping block 5, without the need for complex auxiliary parts and with simple installation.

[0033] Using the U-shaped clamp 6 and the locking nut 7 can significantly improve the gripping force of the housing 1 on the optical cable 2 and related components, ensuring that the optical cable 2 can be firmly fixed in the predetermined position under various external conditions. Since no complex auxiliary parts are required, the installation process becomes simpler and faster. Just place the optical cable 2 and related components into the housing 1, and then fix them with the U-shaped clamp 6 and the locking nut 7.

[0034] The simplified design means reduced material consumption and installation time, thus reducing the overall installation cost. The design of the U-shaped clamp 6 and the locking nut 7 provides a reliable fixing mechanism, reducing the risk of failures caused by improper installation or insecure fixation. The simplified structure makes maintenance work easier to carry out. If it is necessary to inspect or replace the optical cable 2, the maintenance personnel can quickly loosen the locking nut 7 and take out the optical cable 2 and related components.

[0035] Due to the simple and intuitive installation process, the installation errors caused by complex operations of the operators are reduced. The reliable fixing method reduces the risk of the optical cable 2 falling off due to vibration and other reasons, improving the safety of the power system. In short, this designed preformed suspension clamp for electric power is not only convenient for installation, but also improves the fixing efficiency and safety, while reducing the installation and maintenance costs, and is a practical fixing solution in the power system.
