Description

A wire rope vibration reduction device for cable

Technical Field

The utility model relates to the technical field of cable vibration reduction, in particular to a steel wire rope vibration reduction device for a cable.

Background Art

The steel wire rope of the cable refers to the inclined steel wire rope on both sides of the bridge, which is commonly seen on bridges with larger spans. These inclined cables are relatively long and cause vibration of the cables when affected by the bridge deck and external airflow. The vibration of the cables often increases the load on the fixings at both ends and reduces the stability of the fixings. Therefore, limiting the vibration of the cables has a greater impact on the stability of the bridge.

A common cause of cable vibration is that the cable has low motion damping and is easily disturbed by external factors. Currently, the vibration reduction of the cable mainly involves installing dampers at the position where the cable is fixed to the bridge body to reduce the vibration of the cable. However, the vibration reduction effect is limited, and it cannot be flexibly adjusted to vibrations of different intensities, resulting in the inability to increase the stability of the fixation when the cable vibrates too much, thereby reducing the stabilizing effect on the cable.

Utility Model Content

In view of the above background technology, the prior art has the problem that it cannot flexibly adjust to vibrations of different intensities, resulting in the inability to increase the stability of the fixation when the cable vibrates too much, thereby reducing the insufficient and defective stabilizing effect on the cable.

The utility model discloses a wire rope vibration reduction device for a cable, comprising a base, a cable is arranged above the base, a clamping mechanism is arranged on the outer surface of the cable, a vibration sensor is arranged inside the clamping mechanism, a buffer mechanism is arranged on one side of the clamping mechanism, a connecting tube is arranged on the other side of the buffer mechanism, a telescopic rod is fixedly connected to the outer surface of the connecting tube, a sliding ring is fixedly connected to the bottom of the telescopic rod, a first spring is fixedly connected to the bottom of the sliding ring, a first piston rod is fixedly connected to the bottom of the first spring, the outer surface of the first piston rod is slidably connected to the inner wall of the connecting tube, and a damper is arranged at the bottom of the first piston rod.

Furthermore, a photovoltaic panel is fixedly connected to the upper surface of the base, and the bottom of the damper is fixedly mounted on the upper surface of the base.

Furthermore, the clamping mechanism includes an arc-shaped cylinder, one side of which is fixedly connected to the vibration sensor, and the interiors of the two arc-shaped cylinders are buckled onto the outsides of the cables.

Furthermore, a second spring is fixedly connected to one side of the interior of the arc-shaped cylinder, and a control board is fixedly connected to the top of the second spring.

Furthermore, a clamping block is fixedly connected to the top of the control panel, the top of the clamping block is inserted into the interior of the arc block, and one side of the arc block is fixedly connected to the arc tube.

Furthermore, the buffer mechanism comprises a fixed cylinder, an inner wall of the fixed cylinder is slidably connected with a second piston rod, and one end of the second piston rod is arranged on the outer surface of the arc-shaped cylinder.

Furthermore, one end of the fixed tube is fixedly connected to the flow limiting tube, and the other end of the flow limiting tube is fixedly connected to the connecting tube.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. The utility model arranges the vibration sensor on the outside of the cable through the clamping mechanism, so that the vibration sensor detects the vibration of the cable, and then drives the second spring and the first piston rod to move through the telescopic rod, and strengthens the fixing effect of the cable through the buffer mechanism to reduce the vibration of the cable, thereby solving the problem that the cable cannot be flexibly adjusted when the vibration of the cable is too large, resulting in the inability to increase the stability of the fixation when the vibration of the cable is too large, thereby reducing the stabilizing effect of the cable.

A rubber pad is provided inside the arc-shaped cylinder 301, and the rubber pad is in contact with the outer surface of the cable 2 to achieve tight compression on the outer surface of the cable 2, so as to fix the clamping mechanism 3 on the upper side of the cable 2.

Please refer to Figure 3. A second spring 303 is fixedly connected to one side of the interior of the arc-shaped tube 301. A control board 304 is fixedly connected to the top of the second spring 303. The top of the control board 304 includes two circular rods, and the circular rods all pass through the top of the arc-shaped tube 301, so that the control board 304 can be pushed downward by the circular rods to squeeze the second spring 303.

Please refer to Figures 2 and 4. A card block 305 is fixedly connected to the top of the control board 304. The top of the card block 305 is inserted into the interior of the arc block 302.

At the same time, the arc-shaped blocks 302 of the two arc-shaped cylinders 301 are respectively inserted into the inside of the opposite arc-shaped cylinder 301, and the inclined surface of the clamping block 305 is squeezed, so that the clamping block 305 first squeezes the second spring 303 through the control board 304. After the arc-shaped block 302 is completely inserted into the inside, the clamping block 305 is inserted into the inside of the arc-shaped block 302 driven by the second spring 303. The two arc-shaped cylinders 301 are locked and sleeved on the outside of the cable 2, and then the vibration sensor 11 on the arc-shaped cylinder 301 detects the vibration amplitude of the cable 2, and appropriately controls the telescopic rod 6 to work.
