Description

Technical Field

[0001] The present application relates to the technical field of overhead power lines and cable construction, and in particular to an anti-slip multi-frequency vibration damper. Background Art

[0002] The vibration damper is provided to reduce the vibration of the wire caused by the wind. The pole positions of high-voltage overhead lines are relatively high and the span is relatively large. When the cable is affected by the wind, it will vibrate, and the cable will be fatigued and damaged due to periodic bending. When the span of the overhead line is greater than 120 meters, a vibration damper is generally used for vibration prevention.

[0003] In the related art, when installing the cable on the vibration damper, the staff first winds the preformed wire on the surface of the cable at high altitude, and then fixes the vibration damper outside the preformed wire. The process of installing the preformed wire is cumbersome, and the staff working at high altitude for a long time has potential safety hazards. Summary of the Invention

[0004] In order to improve the installation speed of the preformed wire, the present application provides an anti-slip multi-frequency vibration damper.

[0005] The anti-slip multi-frequency vibration damper provided by the present application adopts the following technical solutions:

[0006] An anti-slip multi-frequency vibration damper includes a clamp body. A number of wound preformed wires are arranged inside the clamp body. An anti-vibration component is arranged below the clamp body. Pre-installed pieces are arranged at both ends of the preformed wire. A clamping component is arranged on the pre-installed piece. The clamping component is used to connect and fix both ends of the pre-installed piece to form a pre-installed ring. The pre-installed ring is sleeved outside a number of wound preformed wires. A number of connecting blocks corresponding to the number of preformed wires are arranged on the inner wall of the pre-installed ring. A pre-installed groove is formed between two adjacent connecting blocks. The preformed wire is clamped in the corresponding pre-installed groove. The clamping component includes a clamping piece arranged at one end of the pre-installed piece. A clamping groove is formed at the other end of the pre-installed piece. The clamping piece extends into the clamping groove.

[0007] By adopting the above technical solutions, when installing the preformed wire on the cable, the two ends of the preformed wire can be correspondingly clamped on the pre-installed piece first, and then the assembled preformed wire and the pre-installed piece are sleeved on the cable. The clamping component is used to connect both ends of the pre-installed piece to form a pre-installed ring sleeved on the surface of the cable, which is beneficial for the staff to quickly install the preformed wire on the surface of the cable. In addition, the two ends of the pre-installed piece are connected and fixed by inserting the clamping piece into the clamping groove.

[0008] Optionally, a fastening piece is slidably connected to the side of the pre-installed piece away from the preformed wire. Both ends of the fastening piece are clamped to form a fastening ring. The fastening ring is threadedly connected to the pre-installed ring.

[0009] By adopting the above technical solution, a fastening ring formed by clamping both ends of a fastening piece is sleeved on the surface of a pre-installed ring, and the pre-installed ring is fixed through the threaded connection between the fastening ring and the pre-installed ring.

[0010] Optionally, several first fixing blocks are arranged on one side of the fastening ring close to the pre-installed piece, and second fixing blocks corresponding to the number of the first fixing blocks are provided on the clamping piece, and the second fixing blocks and the first fixing blocks are arranged in a staggered manner.

[0011] By adopting the above technical solution, due to the staggered arrangement of the second fixing blocks and the first fixing blocks, the fastening ring and the clamping piece are locked with each other, avoiding the loosening of the pre-installed ring caused by the falling off of the clamping piece.

[0012] Optionally, a locking piece is rotatably connected to the fastening piece, and locking rings are formed by clamping both ends of the locking piece, and the locking rings are in threaded connection with the pre-installed ring.

[0013] By adopting the above technical solution, through the threaded connection between the locking ring and the pre-installed ring, the fastening ring is fixed, avoiding the clamping piece from retreating from the groove and loosening due to the rotation of the fastening piece.

[0014] Optionally, several rubber gaskets in contact with the cable are arranged inside several wound preformed strands. An arc-shaped concave surface is arranged on the surface of the rubber gasket away from the cable. An arc-shaped convex block extending into the arc-shaped concave surface is arranged on one side of the clamp body close to the preformed strand. The arc-shaped convex block abuts against the preformed strand. Several tension springs are embedded in the rubber gasket, and after the two ends of the tension spring are clamped, they are sleeved on the cable.

[0015] By adopting the above technical solution, several rubber gaskets are attached to the surface of the cable, which is beneficial to increasing the friction between the preformed strand and the cable. In addition, the arc-shaped concave surface arranged on the rubber gasket enables the arc-shaped convex block to press the preformed strand into the arc-shaped concave surface, thereby fixing the clamp body and the preformed strand, and avoiding the clamp body from sliding on the preformed strand, which is beneficial to improving the anti-slip property of the clamp body.

[0016] Optionally, the clamp body includes a wire board and a gland. The wire board is rotatably connected to the gland. A fastener for fixing with the gland is arranged on the wire board. A through hole is arranged on the gland. The fastener passes through the through hole, and the surface of the gland at the through hole abuts against the fastener.

[0017] By adopting the above technical solution, it is convenient for the staff to install the clamp body on the cable. At the same time, the fastening property between the wire board and the gland is further improved through the fastener. In addition, it is convenient for the staff to dock the gland and the fastener, which is beneficial to improving the installation speed of the staff.

[0018] Optionally, the anti-vibration component includes a steel strand arranged on the wire board. Hammer bodies are arranged at both ends of the steel strand, and the distances from the two hammer bodies to the wire board are corresponding.

[0019] By adopting the above technical solution, the distances from the two hammer bodies to the wire board are the same, making the amplitudes corresponding when the hammer bodies vibrate, which is beneficial to improving the anti-vibration performance.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When installing the preformed stranding wires on the cable in the present application, the two ends of the preformed stranding wires can be first correspondingly clamped on the pre-installed pieces, and then the assembled preformed stranding wires and the pre-installed pieces are sleeved on the cable, and the two ends of the pre-installed pieces are connected by the clamping assembly to form a pre-installed ring sleeved on the surface of the cable, which is beneficial for the staff to quickly install the preformed stranding wires on the surface of the cable.

[0022] 2. After the preformed stranding wires are installed in the present application, the preformed stranding wires form an arc-shaped concave surface on the rubber gasket, and the wire clamp body is installed in the arc-shaped concave surface, which is beneficial to improving the anti-slip property of the wire clamp body.
