Background
The elevator is essential lifting tool among people's daily life, and it is the basic equipment of preparing of modern high building construction, produces low frequency noise easily during the elevator operation, can influence passenger's travelling comfort. It is an important subject to eliminate low frequency noise generated when the elevator is operated. Aiming at low-frequency noise generated in the operation of an elevator, two main modes are provided in the industry, namely, a damping pad is added at the bottom of a car to isolate the car from a car frame and reduce vibration generated in the operation of the elevator; and the other type of the elevator car top wheel is added with shock absorption to reduce the shock generated when the car top wheel rotates. However, some vibration of the existing modes of the pointer to the car cannot prevent sound pollution caused by low-frequency resonance generated by the vibration generated by the steel wire rope and the wheels and transmitted to the wall body of a building through the rope head combination and the steel beam, so that the noise is gradually reduced through the rope head combination at present.
Disclose a rope hitch plate subassembly and elevator as in 202021931537.7's patent, rope hitch plate subassembly is provided with the arch shaped plate, and the arch shaped plate is compared with the flat board, has bigger bearing limit, difficult rupture, and the arch shaped plate can produce deformation easily when atress suddenly, can play the absorbing effect of buffering, nevertheless under vibrations are strikeed, and the arch shaped plate can take place deformation to the change can take place in second through-hole position, produces great power to the rope hitch bar, leads to the fact the damage to the rope hitch bar easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a vibration/noise reduction fag end composite set. The low-frequency noise generated during the operation of the elevator can be reduced, and the rope head rod is not easy to damage.
The technical scheme of the utility model: the utility model provides a vibration/noise reduction fag end composite set, includes lower fag end board, lower fag end board upper end middle part be equipped with the rubber pad, the rubber pad is equipped with the stop collar of fixing in fag end board down all around, is equipped with the guide post in the stop collar, the guide post upper end is equipped with the fag end board, the terminal surface offsets with the rubber pad under the fag end board, lower fag end board, rubber pad and the fag end board are equipped with the fag end stick through the fixed orifices at middle part, fag end board one side is equipped with the detection switch corresponding with the fag end board down.
Among the aforementioned damping and noise reduction fag end composite set, lower rope hitch plate be equipped with the mounting hole all around, be equipped with oil-free sliding bearing in the mounting hole, stop collar and guide post lower extreme pass oil-free sliding bearing and fix through two nuts.
In the aforementioned rope head combination device for shock absorption and noise reduction, the distance from the trigger point of the detection switch to the upper rope head plate is 15% of the thickness of the rubber pad.
In the aforementioned rope head assembly for shock absorption and noise reduction, one end of the upper rope head plate exceeds the lower rope head plate in length, and is opposite to the detection switch.
Compared with the prior art, the utility model discloses a vibrations that wire rope and wheel produced are absorbed to the rubber pad, avoid vibrations indirect transmission girder steel and wall body to produce low frequency resonance to when last rope hitch plate receives vibrations, stop collar and guide post can cooperate to lead spacingly to last rope hitch plate, avoid going up the rope hitch plate skew to produce the damage to rope hitch plate, the rubber pad is at the shock attenuation in-process, the rubber pad can become invalid gradually, can trigger detection switch when becoming invalid, thereby remind the staff to carry out the change of rubber pad, the reliability is better.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A shock-absorbing and noise-reducing rope head combination device is shown in figures 1-3 and comprises a lower rope head plate 1, wherein a rubber pad 2 is arranged in the middle of the upper end of the lower rope head plate 1, limiting sleeves 3 fixed in the lower rope head plate 1 are arranged on the periphery of the rubber pad 2, guide columns 5 are arranged in the limiting sleeves 3, an upper rope head plate 6 is arranged at the upper ends of the guide columns 5, the lower end face of the upper rope head plate 6 abuts against the rubber pad 2, a rope head rod 8 is arranged on the lower rope head plate 1, the rubber pad 2 and the upper rope head plate 6 through a fixing hole 7 in the middle, and a detection switch 9 corresponding to the upper rope head plate 6 is arranged on one side of the lower rope head plate 1.
Lower rope hitch plate 1 be equipped with mounting hole 10 all around, be equipped with oil-free bearing 11 in the mounting hole 10, stop collar 3 and 5 lower extremes of guide post pass oil-free bearing 11 and fixed through two nuts.
The distance between the trigger point of the detection switch 9 and the upper rope hitch plate 6 is 15% of the thickness of the rubber pad 2.
One end of the upper rope hitch plate 6 exceeds the lower rope hitch plate 1 in length and is opposite to the detection switch 9.
The principle of the utility model is as follows: when the elevator operates, the vibration generated by the steel wire rope and the wheels can be transmitted to the rope hitch plate 6, the rope hitch plate 6 can transmit the vibration to the rubber pad 2, meanwhile, the rope hitch plate 6 can realize the guiding effect under the effects of the limiting sleeve 3 and the guide column 5 when vibrating, the upper rope hitch plate 6 is prevented from vibrating to shift, because the rope head rod 8 is fixed in the fixing hole 7 of the upper rope hitch plate 6, if the rope hitch plate 6 shifts, the fixing hole 7 can generate pressure on the rope head rod 8, the damage of the rope head rod and the guide column is caused, the rubber pad 2 can absorb the vibration, the vibration is prevented from being indirectly transmitted to the steel beam and a wall to generate low-frequency resonance, so that the low-frequency noise generated when the elevator operates is reduced, the rubber pad 2 has certain fatigue limit, when the displacement generated by aging or elevator overload of the rubber pad 2 exceeds 15% of the thickness of the rubber pad, the upper rope hitch plate 6 can trigger the detection switch 9, thereby reminding a worker to replace the rubber pad 2, and the reliability is better.
