Abstract

The utility model relates to a bracing cable vibration absorber which relates to the technical field of the application of building bracing cables. The utility model is provided with a cable hoop and a container connected with the cable hoop, wherein a movable inertia block is installed in the container and springs are installed between the inertia block and the container. The bracing cable vibration absorber is installed on the building bracing cables to reduce the vibration of the bracing cables; compared with the prior art, the utility model can absorb and reduce the vibration of various bracing cables, can extend the fatigue service life of the bracing cables and has the advantages of notable social benefit, simple structure, small volume and convenient installation.

Description

The pulling cable damping device
Technical field
The utility model relates to the building guy cable applied technical field, especially a kind of device that is used for reducing the building guy cable vibration.
Background technique
Building guy cable in use can vibrate, and this vibration can reduce the fatigue life of drag-line, and in order to reduce to alleviate the vibration of drag-line, people have adopted two kinds of solutions.A kind of scheme is with cable many drag-lines to be linked mutually; Another kind of scheme is used on the bridge, and it is the device that adds a spring-like on bridge floor in addition.These schemes can only change the vibration mode of drag-line or comparatively speaking the vibration that certain recurrent influence factor produced are inhibited, and the oscillating action that other factors is caused is little.
Summary of the invention
Subject matter to be solved in the utility model provides a kind of pulling cable damping device that various types of inhaul cable vibrations is all had good inhibition effect.
In order to address the above problem, the scheme that the utility model adopts is: it has parrel and the container that is connected with this parrel, and movable inertial mass is housed in the described container, between described inertial mass and described container spring is housed.
Other space in the said vesse can be equipped with liquid substance and be played damping function; Above-mentioned container can be made of with the upper end cap and the lower end cap that are contained in these cylindrical shell two ends the cylindrical shell of a circle, described parrel can be connected with described upper end cap, it is cylindrical body that described inertial mass then can be made into, be provided with spring base hole in it, the upper end of described spring is contained in the described spring base hole, and the lower end of this spring is connected on the described lower end cap.
Above-mentioned parrel is meant that employing is around holding the part that fixedly connected mode is waled drag-line tightly; The inertial mass of described activity be meant can be in container movable object; The aforesaid liquid material can be a liquid oils, also can be other material that is liquid condition under the drag-line working environment, and its effect is the motion generation damping to the inertial mass of activity.
Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:
1, owing to the parrel that is connected with drag-line links to each other with the container of a built-in spring and inertial mass, therefore, the various vibrations of drag-line all can reduce because of being absorbed by the motion of spring and inertial mass, especially, when in container, liquid substance being housed, the kinetic energy that the vibration of drag-line also can bring it inertial mass is converted into the heat energy as the liquid substance of damping function, thereby can more effectively reduce the vibration of drag-line.
2, simple in structure, volume is little, and is easy for installation.
3, can effectively improve the fatigue life of drag-line, have remarkable social benefit.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Among the embodiment shown in Figure 1, the utility model has a parrel that is connected to form by bolt 7 by arc plate 8 and arc plate 6, the lower end of arc plate 6 is connected with one and constitutes airtight container by circular cylinder body 2, the upper end cap 5 that is contained in these cylindrical shell two ends and lower end cap 1, the cylinder bodily form inertial mass 3 that can move up and down in container is housed in the container, be provided with spring base hole in the inertial mass 3, spring 4 is housed in this spring base hole, the lower end of spring 4 be connected lower end cap 1 above, fill with machinery oil 9 in other space in the container.
In use, the arc plate 8 of parrel and arc plate 6 are fastened on the drag-line 10 by bolt 7, the vibration of drag-line 10 drives the container accompany movement by parrel, and the inertial mass 3 in the container, produce relative movement according to its inertia and container, the kinetic energy of this relative movement is converted into the heat energy of machinery oil 9 in the container, thereby absorbs and reduce the vibration of drag-line 10 effectively.

Claims (2)

1, a kind of pulling cable damping device is characterized in that: it has parrel and the container that is connected with this parrel, and movable inertial mass is housed in the described container, between described inertial mass and described container spring is housed.
2, pulling cable damping device according to claim 1 is characterized in that: described container is made of a circular cylinder body and the upper end cap and the lower end cap that are contained in these cylindrical shell two ends; Described parrel is connected with described upper end cap; Described inertial mass is a cylindrical body, is provided with spring base hole in it; The upper end of described spring is contained in the described spring base hole, and the lower end of this spring is connected on the described lower end cap.
