Abstract
The utility model relates to a wire reel vibration damper for a vehicle-carrying communication device, which is mainly composed of an upper and a lower fixing plates and a wire reel damper. The upper and the lower fixing plates and the wire reel damper are connected together by screw bolts and screw holes, thus, forming the integration. A wire reel is formed by winding a wire rope which is provided with multiple strands and has the right and left cross lay, adopts a trapezoid winding method, and has a symmetric distribution form. When the external disturbance force acts on the utility model and transfers to the vehicle-carrying communication device, the peak acceleration generated by the vehicle-carrying communication device can be less than or equal to the allowable acceleration, and the balanced state is kept. The utility model has the advantages of strong anti-external disturbance ability, small vibrating and amplifying coefficient, good buffering performance, three-way anti-vibration performance, long service life, etc.
Description
The utility model belongs to the improvement of the used shock absorption device of vehicular communication equipment.
Usually, be installed in the communication facilities on crawler type or the rubber-tyred vehicle,, often be subjected to the effect of external disturbance power such as strong vibration, impact simultaneously, have a strong impact on normally carrying out of communication work because physical environment is very abominable around it.In order to alleviate the influence of these exciting forces, currently used method has two kinds: a kind of is active vibration damping, promptly improve the structural strength and the rigidity of vehicular communication equipment self, but this can make the communication facilities volume too bigger than normal, heavy, and interior space is limited, difficulty is installed, and involves great expense, inconvenience is adopted.Another kind is a passive energy dissipation, a shock absorption device promptly is installed between communication facilities and vehicle, as the rubber-metal shock absorption device, in order to vibratory force and the acyclic impulsive force that alleviates external cycles, but it only can folk prescription to damping, visual observation has obviously rocks, and the rubber-metal vibration isolator is aging easily, poor reliability, service life is short, is not optimal shock-dampening method.
The purpose of this utility model just is to remedy the deficiencies in the prior art, replace the rubber-metal vibration isolator with the wire reel vibration isolator that designs and produces voluntarily, be fixed in a kind of wire reel shock absorption device that is used for vehicular communication equipment that forms between two purpose made metal sheets.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a wire reel vibration isolator structural representation.
As can be seen from Figure 1: the utility model mainly is made of 1 upper mounted plate 7,1 bottom plate 8 and 4 wire reel vibration isolators 9. By bolt 6 and screwed hole 5 wire reel vibration isolator and upper and lower fixing plate are coupled together, form an indivisible integral body. It can also be seen that from Fig. 2: wire reel vibration isolator 9 is made of with the pressing plate 2 of counterbore and 2 pressing plates with threaded hole 3 and several sunk screws 41 wire reel 1,2 again. Wire reel is to adopt trapezoidal coiling method also to be wound on the particular manufacturing craft with symmetrical form with 1 multistrand rope to be shaped. The wire reel that will be shaped by sunk screw with pressing plate and pressing plate with threaded hole with countersunk head again clamps reinforces, and then thread mill drilling 5, at last it is prevented " three the is anti-" processing such as dipping, mould proof, anti-salt fog, improve the reliability of its integral shock-absorbing to advance the upper step.
In the utility model, according to the influence of upper and lower pressing plate four limit length of side ratios and stressed size thereof, the wire reel vibration isolator 9 used steel rope number of turns divide 8 circles and 10 to enclose two kinds again.And 2 wire reels that contain 10 circles are installed in respectively between the both sides of upper and lower pressing plate narrower (weak point) every device, and 2 wire reel vibration isolators that contain 8 circles are installed in respectively between the both sides of upper and lower pressing plate broad (length).Therefore, when the extraneous interference masterpiece is used on the utility model, because it has the rigidity of change and change damping force characteristics, and has enough strength and stiffness, so can bear the effect of big extraneous interference power permanent deformation and unstable phenomenon do not take place.In other words, when the extraneous interference masterpiece is used for the utility model and passes to vehicular communication equipment, the peak acceleration a that this equipment is produced
MaxThe acceleration/accel a allowable that is less than or equal to this equipment
0Like this, both made when the frequency change of external exciting force, and also can remain good state of equilibrium.In addition, because wire reel 1 is the steel rope of 1 multiply left and right sides houser lay, deformation space is bigger like this, promptly work as the utility model and be subjected to the extraneous interference masterpiece time spent, can twist in opposite directions with bending between each steel wire and produce the metal dry-friction damping, this damping can change the energy of extraneous interference power into heat energy, and in time rapid the dissipation discharges, absorb the purpose of extraneous interference energy to reach maximum limit ground, thereby guarantee that vehicular communication equipment is not had enough to meet the need the influence of physics environmental change.
Remarkable advantage of the present utility model has 3 aspects:
1, vibration aspect:
The utility model is good than the damping performance of rubber-metal shock absorption device.Little and the energy three-dimensional damping of resonance coefficient of amplification.Particular case sees the following form:
| Resonance frequency (HZ) | The resonance coefficient of amplification | Damping modes | Visual observation | |
| The utility model | X is to 7 | 2.0～2.3 | Can the three-dimensional damping | Steadily |
| Y is to 7 | 1.2～1.3 | |||
| Z is to 17 | 1.3～1.9 | |||
| The rubber-metal shock absorption device | Z is to 16.8～2.0 | 6.1～6.46 | Only can Z to damping | Can see obviously and rock |
2, impact aspect
This product is with novel good than rubber-metal shock absorption device cushion characteristic, and its aftershock is little nearly 3 times and can recover rapidly.Particular case sees the following form:
| The average acceleration at place in the middle of the vehicular communication equipment shell | Visual observation | |
| The utility model | 15.5 | Steadily |
| The rubber-metal shock absorption device | 40.5 | Have obviously and rock |
3, others:
The utility model is than rubber-metal shock absorption device long service life, is difficult for aging and has the rigidity of change, becomes damping force characteristics, and adaptive capacity to environment is strong, and " three is anti-" characteristic is good, simple in structure, and mounting or dismounting are convenient.Particular case sees the following form:
| Use warranty time | Environmental adaptability | Produce maintenance | |
| The utility model | Still be difficult for ageing failure in 60 months | By force | Produce convenient mounting or dismounting easily |
| The rubber-metal shock absorption device | Easily old inefficacy the after 12 months |
Fig. 1 also is the utility model embodiment.Wherein, stainless steel wire rope 1 is 133 strands, diameter is 3mm, the pressing plate 2 of band counterbore, pressing plate 3 with threaded hole, bottom plate 8 are all made for the 08F steel plate of 3mm with thick, and upper mounted plate 7 usefulness are thick to be made for the 08F steel plate of 2mm, flathead screw 4 specifications are M4 * 6, totally 72, tapped bore 5 specifications are that M5, bolt 6 specifications are M5 * 12, each 16.
