Description
Technical field
The present invention relates to a kind of bridge construction building component, particularly a kind of shock absorber.
Background technology
It is to suppress comparatively one of effective measures of inhaul cable vibration that damper is installed in guy system; Wherein the utilization of stickiness shearing type damper and hydraulic damper is maximum, and technology maturation, its reliability have obtained engineering and used confirmation; But stickiness shearing type damper and hydraulic damper volume are larger, and cost is high, mostly is external; Because each damper can only provide an axial damping force, so a drag-line generally need to be installed the vibration that two or more dampers that form an angle are controlled the drag-line all directions; Because support needs larger installing space, support the whole view that affect bridge, the larger limitation of existence in small bridge be set.And employed damping energy dissipation material is viscous fluid substantially in stickiness shearing type damper and the oil damper, works under the Long-term Vibration state, and Seepage very easily occurs, and causes the damper vibration damping effect greatly to reduce or finally loses effect; Maintenance, replacement cost is higher, and the durability of damper can not be guaranteed.
For the drag-line that the external damper can't be installed, the modes of built-in damped rubber ring being installed in the built-in pipe exit that adopt more; This mode is to utilize the extruding of damped rubber ring to consume energy to suppress the vibration of drag-line, and stock utilization is low, and effectiveness in vibration suppression is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of internally-arranged type " with the shearing rubber cushion assembly of Fastening device for cable " that is installed in drag-line built-in pipe exit, this damper can take full advantage of high-damping rubber shear energy dissipation performance, avoids the shortcoming of stickiness shearing type damper and oil damper leakage loss.
The technical scheme that addresses the above problem is: a kind of shearing rubber cushion assembly with Fastening device for cable comprises Fastening device for cable, n rubber monomer damper and linkage;
Described Fastening device for cable comprises cord clip, connecting bolt, lay respectively at the upper junction plate of cord clip upper end and be positioned at the lower connecting plate of cord clip bottom, between the upper lower connecting plate reinforcing rib is arranged, have on the lower connecting plate for the elongated slot I of adjusting cable body and built-in pipe alignment error;
Described each rubber monomer damper comprises the high-damping rubber monomer, is positioned at the steel plate at high-damping rubber monomer two ends, with the connecting bolt that steel plate is fixedly connected with by welding manner, the high-damping rubber monomer is connected by vulcanization with the steel plate that is positioned at high-damping rubber monomer two ends;
Described linkage comprises upper and lower terminal pad, connects the cylindrical shell of upper and lower terminal pad; Have on the lower terminal pad for the elongated slot II of adjusting cable body and built-in pipe alignment error;
During use, an end of n rubber monomer damper links to each other with drag-line built-in pipe on being fixed on bridge floor by means of the flange that is welded on embedded pipe orifice by linkage, and the other end links to each other with the lower connecting plate of Fastening device for cable; The cord clip of Fastening device for cable is fixed on the drag-line cable body by the form of anchor ear, and the span of said n is: n is the arbitrary integer between 3～50.
Its further technical scheme is: described rubber monomer damper is cylindrical rubber monomer damper, or shape of cross section is fan-shaped or square or the column rubber monomer damper of m limit shape, and m is the arbitrary integer of 3-12.
Because adopt said structure, the present invention's the shearing rubber cushion assembly with Fastening device for cable has the following advantages and effect:
1. this damper of the present invention is owing to adopt high-damping rubber monomer shear energy dissipation mode to replace the mode of traditional damped rubber ring extruding power consumption, and the energy dissipation behavior of damping material is able to maximum using, and damping property is greatly improved:
High-damping rubber has higher damping and damping capacity, is a kind of viscous-elastic material, namely has the character of elastic solid (Hookean body), shows as again the characteristic of viscous fluid, has very high damping characteristic, and its shear energy dissipation performance is better than extrusion performance; The present invention takes full advantage of this characteristic of high-damping rubber, and the energy dissipation behavior of damping material is able to maximum using, and damping property is greatly improved.
2. the rubber monomer damper adopts the Standardisation Cell design, cost is low: the present invention's the damping original paper with the shearing rubber cushion assembly of Fastening device for cable is the rubber monomer damper, during use the different model drag-line is passed through the drag-line kinematic analysis, needs according to stressed and vibration damping, n the rubber monomer damper 3 of choosing some evenly or other arrangement forms be installed on the drag-line excircle, form the shearing rubber cushion assembly of drag-line; Can realize having avoided the different model drag-line is equipped with the drawback that different big or small dampers need to redesign for the design of rubber monomer damper Standardisation Cell, reduce the damper manufacturing cost.
3. the mode by Fastening device for cable and damper designs are integrated can be simplified the guy system structure; Simultaneously with respect to original mounting means, can make Fastening device for cable be installed on position further from anchor point, reduced the knuckle of steel strand, be conducive to improve the anti-fatigue performance of drag-line.
4. the present invention's the shearing rubber cushion assembly with Fastening device for cable is installed in drag-line built-in pipe exit, need to complicated support arm be set at bridge floor, has the characteristics such as easy for installation, simple structure, maintenance cost are low, replaceable.
