A kind of tuned mass damper with protective device.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of tuned mass damper with protective device, including the mass block top plate being mounted in building structure, institute
Stating mass block top plate lower part is mass block, is damper and spring, the mass block top plate between mass block and mass block top plate
Being additionally provided between mass block prevents mass block from taking off the wirerope fallen, and the end of wirerope is equipped with the wiring of column wirerope
Device, column wirerope electric wire connecting junction are located on mass block top plate or on mass block.
Scheme as a further preference, using the column wirerope electric wire connecting junction of end welding on the mass block top plate,
One end of the wirerope is fastened on column wirerope electric wire connecting junction connector, and another end is fastened on mass block.
Scheme as a further preference, at least provided with two groups of springs between the mass block and mass block top plate.
Scheme as a further preference, at least provided with two wirerope between the mass block top plate and mass block.
Scheme as a further preference, the length of the wirerope are greater than the maximum tension length of spring.
Scheme as a further preference is provided with a circle snub rope on the wirerope, and the end of snub rope is fixed on
On mass block top plate.
Scheme as a further preference, at least provided with the snub rope Liang Quan, the connection of the snub rope Liang Quan on the wirerope
Position on wirerope is the position of equal part wirerope overall length.
Compared with prior art, a kind of tuned mass damper with protective device of the utility model, spring is in length
Time bearing load and impact, it may occur however that spring failure causes mass block there is a situation where falling, and protective device can confront
Gauge block is drawn, and prevents mass block from falling, and eliminates security risk.

Specific embodiment
The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.
As shown in Figure 1, a kind of tuned mass damper with protective device, the hanging tuned mass damper under
Defect improves, and adds protective device to it, it is ensured that product stable safe handling in the structure includes being mounted on to build in structure
The lower section of mass block top plate 2 on building structure 1, mass block top plate 2 is provided with mass block 7, mass block top plate by the suspension of spring 3
Wirerope 5 is additionally provided between 2 and mass block 7, the length of wirerope 5 is greater than the maximum tension length of spring 3, that is to say, that
Spring 3 is stretched in compression limit state, and wirerope 5 remains the state of not stressing.
Further, there is column wirerope electric wire connecting junction 4, described 5 one end of wirerope is connected and fixed on mass block top plate 2
On 4 connector of column wirerope electric wire connecting junction, the other end is fastened on mass block 7.
Further, at least provided with two groups of springs 3 between mass block 7 and mass block top plate 2；Mass block top plate 2 with
At least provided with two wirerope 5 between mass block 7.
Under tradition on the basis of hanging tuned mass damper, it is equipped with high-intensitive protection rope, one end passes through tie point and top
Plate is fixed, and the other end is fixed with mass block, and effective length ratio tuned mass damper impulse stroke is bigger.When damper is normal
When work, which is in relaxation shape, is not subject to mass block gravity.When damper spring due to work long hours generate it is tired
After labor or other reasons failure, mass block can fall under the influence of gravity, and wirerope 5 can hold mass block at this time, prevent
Falling accident only occurs.5 structure of wirerope in the utility model is simple, esy to use, safe and reliable, can be widely used in down
In hanging tuned mass damper product.
Under hanging tuned mass damper mounting means be mass block top plate 2 by bolt or welding with building structure 1 connect
It connects, is sling mass block 7 by spring 3.When normal work, mass block 7, which vibrates up and down, has certain amplitude.5 both ends of wirerope
It is connected and fixed respectively with top plate 2 and mass block 7 by column wirerope electric wire connecting junction 4, the effective length ratio mass block 7 of wirerope 5
Vibration amplitude is big.The material that wirerope 5 makes has intensity height, the good feature of high tenacity.Therefore protective device under normal circumstances
In relaxed state, damper work is unaffected.When the spring 3 of damper generates fatigue or other originals due to working long hours
After failure, mass block 7 can fall under the influence of gravity, and wirerope 5 can hold mass block 7 at this time, prevent to fall
Fall accident.
When spring 3 or damper 6 are broken in order to prevent, mass block 7 falls, and the bearing down of moment is larger, holds
The tie point of wirerope 5 or wirerope 5 and top plate 2 and mass block 7 is easily pulled apart, we can be provided with a circle on wirerope 5
Snub rope 8, the end of snub rope 8 are fixed on mass block top plate 2, shorter than the snub rope 8 of this section, when mass block 7 is fallen
When falling, bearing down is acted on first in snub rope 8, if snub rope 8 is broken, remaining bearing down just acts on wirerope 5, gives
The certain cushion effect of wirerope 5.
Further, the position on wirerope 5 at least provided with the snub rope Liang Quan 8, on 8 connecting steel wire ropes 5 of the snub rope Liang Quan
It is set to the position of 5 overall length of equal part wirerope.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
The utility model processed, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
It should be included within the scope of protection of this utility model.
