It is an object of the present invention to provide a vibration isolator for a traffic light that can extremely reduce the repair cost caused by a failure or the like.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, a traffic light vibration isolator according to the present invention is configured as follows.
[0005]
That is, it is a vibration isolator for a traffic light unit attached to a traffic light bracket to be erected, provided with a hanging rod protruding upward from the upper end of the traffic signal unit, and the hanging rod penetrates an upper horizontal member of the traffic light bracket And attached to the signal device bracket via vibration isolating members placed on the signal device bracket on both sides of the suspension rod. Further, the traffic light unit is pivotally supported via a vibration isolating member so as to be rotatable about the lower end surface substantially at the center .
BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
[0006]
For example, a traffic signal for a train is erected on the side of a railroad track.
[0007]
Since such a traffic light is mainly installed near the railroad track, it receives impact, vibration and vibration when passing through the train.
[0008]
And the precision components, circuits, or signal lamps inside delicate traffic lights are likely to fail due to the impact, vibration, and vibration of this product for many years.
[0009]
Here, the traffic signal is supported by a traffic signal holding column and a traffic signal bracket 1 that holds the traffic signal at the upper end of the column.
[0010]
The traffic light bracket 1 is framed in a substantially rectangular shape, and is attached to the column so that the lateral direction is vertically oriented, that is, in a vertically long state.
[0011]
Reference numeral 2 indicates a traffic light unit.
[0012]
The traffic light unit 2 has a predetermined thickness and is formed in a substantially square shape (the one shown in FIGS. 1 and 2 has a vertical rectangular shape, and the four corners are rounded), and the surface side is for a traffic light. A plurality of lamps 3 are provided at predetermined intervals in the vertical direction.
[0013]
In FIG. 2, reference numeral 4 denotes an upper horizontal member constituting the traffic light bracket 1, and the upper horizontal member 4 is made of L-shaped steel having a substantially L-shaped cross section as shown in the figure.
[0014]
Reference numeral 5 denotes a hanging rod projecting upward from the upper end of the traffic signal unit 2, and the hanging rod 5 projects upward through the upper horizontal member 4.
[0015]
A flat pressing member 6 is attached to the tip of the hanging rod 5 so as to protrude in a direction substantially perpendicular to the hanging rod 5, and between the pressing member 6 and the upper horizontal member 4. Upper vibration isolator members 7 are arranged on both sides of the suspension rod 5 and interposed.
[0016]
Thus, the traffic signal unit 2 is in a state of being supported suspended from the upper horizontal member 4 via the vibration isolating member 7.
[0017]
Next, a shaft support portion 8 that pivotally supports the traffic signal unit 2 so as to be rotatable is provided at a substantially central portion of the lower end surface of the traffic signal unit 2.
[0018]
The shaft support 8 is supported by a lower horizontal member 9 that constitutes the traffic light bracket 1, so that the traffic signal unit 2 is rotated to the traffic signal bracket 1 by the upper horizontal material 4 and the lower horizontal material 9. It will be held as possible.
[0019]
Here, as is understood from FIG. 2, the shaft support portion 8 is formed of a cylindrical pipe-like member having a wiring path therein, and a lower vibration-proof member 10 is attached to the intermediate portion.
[0020]
Therefore, this traffic light unit has a vibration-proof structure by the upper vibration-proof member 7 and the lower vibration-proof member 10, and has a structure that can sufficiently absorb shocks, vibrations and vibrations caused by passing through the vehicle.
[0021]
Here, the upper vibration isolation member 7 and the lower vibration isolation member 10 will be described. First, the vibration isolation material for vibration isolation is not limited at all, and examples include vibration isolation rubber and vibration isolation resin.
[0022]
Further, as understood from FIG. 3, the upper vibration isolator 7 has a vibration isolating body 11 having a substantially cylindrical shape formed of a vibration isolating material such as an anti-vibration rubber and an anti-vibration resin. Is surrounded by a substantially loose covering material 12 and the upper and lower surfaces are sealed with metal sealing plates 13 and 13.
[0023]
Next, the lower vibration isolating member 10 also has substantially the same structure as the upper vibration isolating material 7, and the difference is that the through-passage 14 penetrates in the vertical direction inside the vibration isolating body 11 having a substantially cylindrical shape. Is provided.
[0024]
By the way, as an optimal member for the vibration-proof body 11, a gel-like substance containing silicone as a main material can be cited.
[0025]
Here, silicone is a general term for polymers of so-called organosilicon compounds, and is called silicone oil, silicone grease, silicone rubber, silicone resin or the like depending on the state.
[0026]
The characteristics of silicone are due to its molecular structure, and it has high heat resistance, high volatility, and is superior to the same kind of substance in all other properties such as electrical insulation, chemical resistance, weather resistance, and non-volatility. Yes.
[0027]
In addition, a chain polymer is made by scientific treatment (polymerization, condensation), silicone oil with a low degree of polymerization is crosslinked with silicone oil, silicone rubber with a relatively large degree of polymerization, and a chain structure. It is called a silicone resin. The gel is a solidified sol (colloidal solution) in a so-called jelly form. The phenomenon that the sol changes into a gel is called gelation. Examples of the gel include solid agar and gelatin.
[0028]
There is an attractive force between colloidal particles dispersed in the sol, and many sols exhibit structural viscosity. However, when a suitable stimulus is applied to a high concentration, the particles are connected to each other, and the three-dimensional It takes a net-like or honeycomb-like structure.
[0029]
Here, it is preferable that the gel-like substance mainly composed of silicone gel used as the needle-proof main body 11 has a penetration (JIS K2530-1976-50 kg) of 50 to 200.
[0030]
This is because the gel-like substance mainly composed of silicone gel in this region exhibits extremely high characteristics for impact absorption, vibration prevention, and soundproofing effects.
[0031]
In the above, in the traffic signal standing on the side of the railway line, the upper vibration isolator 7 and the lower vibration isolator 10 absorb the shock, vibration and vibration caused by passing the train. And vibration does not reach the traffic light unit 2. Therefore, the traffic light according to the present invention has durability several times that of the prior art.
【The invention's effect】
Thus, the present invention has the above configuration.
[0032]
And according to the vibration isolator of the traffic light according to the present invention, the shock, vibration and vibration generated when the train passes through are not transmitted to the traffic signal unit in which the precision parts are installed, and as a result, used in the traffic signal. The signal lamp does not break due to the aforementioned vibration, etc., and the precision parts such as electric circuits are not damaged by shock, vibration or shaking, and as a result, the life of the traffic light is greatly extended, and the traffic light breaks down. As a result, it is possible to extremely reduce the repair cost that occurs with respect to the above.
