Concrete, described in hold device tightly and include the circular outer cylinder of a upper and lower opening, the bottom of urceolus is set with one The circular inner tube of upper and lower opening, be provided with one piece of circular arc in the urceolus on inner core determines the dynamic of brake shoe and one piece of circular arc Brake shoe, dynamic brake shoe connects and has one to hold screw rod tightly, hold screw rod tightly and stretch out in outside urceolus, holds screw rod tightly by rotation and promotes dynamic Brake shoe can regulate determines brake shoe and the size of circular hole that dynamic brake shoe is enclosed；Hold device tightly to be installed on the top board of square pothole, top The through hole corresponding to holding device centre bore tightly is had on plate.

Concrete, the node after four lifting rope colligations together that described Hanging Basket top connects is by safety rope with lifting rope even Connecing, the tear-strength of safety rope is less than the intensity of lifting rope.When ensureing it with foul, winding, safety rope is pulled off, and Hanging Basket sinks to In water, it is to avoid shipwreck.

Operation principle of the present utility model and work process are as follows:

This utility model inhale energy consumer mainly by Hanging Basket, lifting rope, hold device tightly and rotating cylinder forms.Hanging Basket corner is by level torr Plate is supported on steel box-girder base plate, for reducing friction, arranges circular ball, it is ensured that Hanging Basket can between Hanging Basket corner and horizontal shelf Slide to any direction in horizontal plane.Limit spring is set between Hanging Basket and steel box-girder, it is ensured that occur slightly at steel box-girder Under normal circumstances, Hanging Basket can only occur the least vibration near equilbrium position, is unlikely to drop in vibration.Rotating cylinder is installed on steel Bottom box beam top board, it is connected by lifting rope, safety rope with Hanging Basket, and before Hanging Basket drops from horizontal shelf, lifting rope is around in and turns Drum outer wall.

When bridge twists or during bending vibration under wind effect, causing steel box-girder to rotate, original place is in horizontal The Hanging Basket run-off the straight of state, slide downward under gravity, compress limit spring, when the angle of inclination of steel box-girder exceedes limit value Time, Hanging Basket compression limit spring is turned in water after exceeding limit value at horizontal shelf.

Occur for preventing Hanging Basket from dropping at a high speed unexpected, hold device tightly and lifting rope is in the ordinary course of things light pressure condition, make Hanging Basket slowly falls and falls in water.

Under participating in without manpower or other control device, Hanging Basket enters in water body, tensioning lifting rope under gravity, its consumption And kinetic energy can be transferred to water body principle by steel box-girder and is divided into three phases by steel box-girder one cycle of vibration:

(1) when the steel box-girder of energy consumer rotating cylinder position is by being in extreme lower position and up moving to equilbrium position, Hanging Basket is accelerated motion from lower to upper, the now cover plate closing of Hanging Basket top board limbers, Hanging Basket and Qi Nei water body under lifting rope draws Kinetic energy increases, and drives Hanging Basket part water body flow over and under, and all motive power source drive Hanging Basket work done in lifting rope. Meanwhile, Hanging Basket potential energy also increases, but due in the whole vibration period, Hanging Basket potential energy be changed to zero, do not analyze The change of potential energy.Lifting rope also does negative work to steel box-girder while doing work to Hanging Basket and water body, is equivalent to the part kinetic energy of steel box-girder Water body and Hanging Basket is given by lifting rope transmission.

(2) when the steel box-girder of energy consumer rotating cylinder position is by being in equilbrium position and up moving to extreme higher position, Hanging Basket retarded motion from lower to upper under lifting rope draws, Hanging Basket and Qi Nei water body kinetic energy reduces, but drive equally above Hanging Basket and Section below water body flow, is consumed energy by fluid friction；After Hanging Basket reduces further with the speed that steel box-girder rises, part stream The rate of climb is more than Hanging Basket under effect of inertia for body, and fluid is washed the cover plate of Hanging Basket top board limbers open, now had bigger kinetic energy The water body of density leaves Hanging Basket, and surrounding body supplements and flows into, and forms local partial circulating, and in Hanging Basket, water body kinetic energy runs off rapidly；By Being flexible in lifting rope, Hanging Basket can only be pulled by steel box-girder, and steel box-girder can not be promoted to move, therefore, and the starting stage during this Hanging Basket does negative work to steel box-girder, reduces steel box-girder kinetic energy, and in later stage Hanging Basket, water body kinetic energy flows into surrounding water, and it does not give steel box-girder Acting.

(3) during the steel box-girder of energy consumer rotating cylinder position is by being in extreme higher position and moving down to extreme lower position, Hanging Basket overcomes water body resistance to decline under gravity, and now the cover plate of Hanging Basket top board limbers is washed open by water body resistance, and it can Reduce water body resistance and ensure that Hanging Basket and steel box-girder reach extreme lower position simultaneously.In this process, Hanging Basket potential energy reduces, part gesture Can be by water body Damping work, part potential energy does positive work by lifting rope to steel box-girder, is absorbed by steel box-girder.But due in whole vibration In cycle, Hanging Basket potential energy be changed to zero, Hanging Basket potential variation can not be considered.Therefore, during this, water body is absorbing equally The kinetic energy of steel box-girder.

Under having manpower or other control device to participate in, Hanging Basket enters in water body, tensioning lifting rope under gravity.Pass through Observing, rotate rotating cylinder, lifting Hanging Basket to water surface site, part exposes Hanging Basket top, and rotation is held the screw rod of holding tightly of device tightly and fixed Lifting rope.Now inhale the energy-absorbing of energy consumer and power consumption principle and be divided into three phases by steel box-girder one cycle of vibration:

(1) when holding the steel box-girder of setting position tightly by being in extreme lower position (in the whole immersion water of Hanging Basket) and up moving extremely During equilbrium position, Hanging Basket accelerated motion from lower to upper under lifting rope draws, now the cover plate of Hanging Basket top board limbers is because of water Flowing Guan Bi, Hanging Basket and Qi Nei water body kinetic energy increases, and drives Hanging Basket part water body flow over and under, and all kinetic energy come Come from lifting rope and drive Hanging Basket work done.Meanwhile, Hanging Basket potential energy also increases, but due in the whole vibration period, Hanging Basket Potential energy be changed to zero, the most do not analyze the change of potential energy.Lifting rope also does negative to steel box-girder while doing work to Hanging Basket and water body Merit, the part kinetic energy being equivalent to steel box-girder is given water body and Hanging Basket by lifting rope transmission.

(2) just surfacing when Hanging Basket top board, steel box-girder continues up to move to extreme higher position, exceeds in Hanging Basket The volume of the liquid (water) of the water surface and height increase with Hanging Basket height and increase, and liquid potential energy increase can be considered E=ρ gAh², its Middle ρ is water density, and g is acceleration of gravity, and A is the cross-sectional area promoting liquid, and h is to promote liquid to exceed the height of the water surface； After Hanging Basket rises to certain altitude with steel box-girder, first Hanging Basket housing lower edge exceeds the water surface, and air enters outside Hanging Basket from below Between frame and middle cylinder, in it, liquid flows out Hanging Basket under gravity, and liquid potential energy becomes kinetic energy and enters water body；When steel box-girder continues Continue and up move, middle cylinder lower edge may be caused to exceed the water surface, during in like manner air therefrom cylinder lower edge enters Hanging Basket between cylinder and inner core, In it, liquid flows out Hanging Basket under gravity, and liquid potential energy becomes kinetic energy and enters water body；When steel box-girder continues up to move, can Inner core lower edge can be caused to exceed the water surface, and in like manner air enters inner core from inner core lower edge, and in it, liquid flows out extension under gravity Basket, liquid potential energy becomes kinetic energy and enters water body.

(3) during the steel box-girder of energy consumer rotating cylinder position is by being in extreme higher position and moving down to extreme lower position, Hanging Basket overcomes water body resistance to decline under gravity, and now the cover plate of Hanging Basket top board limbers is washed open by water body resistance, and it can Reduce water body resistance and ensure that Hanging Basket and steel box-girder reach extreme lower position simultaneously.During this, Hanging Basket potential energy reduces, part potential energy By water body Damping work, part potential energy does positive work by lifting rope to steel box-girder, is absorbed by steel box-girder.But due in whole vibration week Interim, Hanging Basket potential energy be changed to zero, Hanging Basket potential variation can not be considered.Therefore, during this, water body is absorbing steel equally The kinetic energy of box beam.

After wind speed reduces, bridge stops occurring significantly to vibrate, and can rotate rotating cylinder, lifting with manpower or other power facility Hanging Basket, and by the handle hole set by steel box-girder base plate, make Hanging Basket install after being tilted into square pothole in place.

Safety rope set below lifting rope can ensure that Hanging Basket is pulled off when running into ship shock, being wound around, it is to avoid unexpected The generation of accident.

The beneficial effects of the utility model and innovative point are as follows:

(1) when without additional governing factor, for there is bridge main beam (steel box-girder) by a relatively large margin, connected by lifting rope Steel box-girder and Hanging Basket, in driving Hanging Basket and the interior and little scope of periphery thereof, in water exercise, (Hanging Basket is always in the water surface to liquid (water) Under), it is achieved steel box-girder kinetic energy passes to Hanging Basket and interior liquid thereof, and in it, liquid has maximum kinetic energy density (kinetic energy/body Long-pending) time, it flows to surrounding water rapidly, takes away liquid kinetic energy in it, it is achieved girder vibrates each cycle and realizes in Hanging Basket Liquid energy-absorbing and row can (arrange to surrounding water, prepare for energy-absorbing next time) once；The motion of Hanging Basket simultaneously, produces with surrounding body Raw friction, consumes partial capability by friction simultaneously.

(2) when there being additional governing factor, Hanging Basket is promoted near water surface site, in each vibration period of girder In, inhaling energy consumer can realize step by step: Hanging Basket and water body friction energy-dissipating (Hanging Basket is in water)；Girder vibration mechanical energy (includes kinetic energy With deformation potential) it is changed into liquid gravitational potential energy in Hanging Basket, gravitional force runs off and enters water body, is no longer converted into girder bobbing machine Tool energy, it is achieved inhale consumption girder vibration mechanical energy, thus suppress girder to vibrate.

(3) Hanging Basket balance when microvariations is kept by elastic limit device.

(4) by elastic limit device, reduce the circular ball rubbed, and the girder utilizing bridge certain amplitude to vibrate inclines Rake angle, it is achieved inhale the Automatic-falling of energy consumer Hanging Basket, thus automatically turn on the work inhaling energy consumer；Work is completed when inhaling energy consumer After work, inhale energy consumer and can the most again playback, wait the startup next time worked, reduce the shadow to Navigation in Navigable to greatest extent Ring.

(5) by Hanging Basket top board limbers and the design of cover plate, during whereabouts, cover plate is opened by hydraulic action, reduces fluid pair Hanging Basket resistance, it is ensured that Hanging Basket sinks rapidly, reaches extreme lower position with steel box-girder simultaneously；Accelerate to rise at steel box-girder traction Hanging Basket Time, cover plate is closed by hydraulic action, it is ensured that in Hanging Basket, water body and Hanging Basket have identical speed, it is achieved the most kinetic energy is from steel Box beam is to the transmission of water body.

(6) design of lifting rope safety rope, it is to avoid the generation of contingency.
