Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an auxiliary barrier for a vehicle for removing stones placed on railroad tracks.

[Conventional technology]

There are two cases of train derailment and overturning accidents caused by placing stones in the past few years, and there is a risk of serious accidents caused by placing stones. Various measures have been taken to prevent accidents caused by this.For example, in addition to making the tracks elevated, auxiliary obstacles have been attached to the barriers to ensure that stones can be removed more reliably.

[Problem that the invention attempts to solve]

As the auxiliary obstruction device, a flat plate made of synthetic rubber or the like is used because it is simple. However, the repulsive force of the flat plate is too strong, and there is a risk that the stones may be thrown to houses near the railway line, causing damage to the houses.

The present invention aims to solve the above problems.

<Means for Solving the Problems> Accordingly, the present invention comprises a substrate, a plurality of brush bristle bundles, and a binding agent, and the substrate has an attachment to a vehicle, and the brush bristle bundles are attached to a vehicle. The brush bristle bundle is such that only the tips of the bristles are exposed to the outside and are bundled by covering the surface from the body to the base with the binding agent. The present invention aims to provide an auxiliary obstacle deflector for a vehicle, wherein the binder is made of a material having appropriate plasticity and elasticity, such as a silicone rubber compound.

[Effect]

Due to the above structure, the auxiliary obstacle remover of the present invention has sufficient repulsive force to remove stones, while the repulsive force is not strong enough to cause damage to human houses, eliminating the drawbacks of rubber plates. be able to.

〔Example〕

Hereinafter, one embodiment will be described based on the drawings.

FIG. 1 is a perspective view showing an auxiliary obstacle shield 1 for a vehicle. The auxiliary obstacle deflector 1 includes two sets of brushes 2, 2 whose brush locking portions 3, 3 are of a channel type (groove type), stacked one on top of the other, and a vehicle mounting tool 4 attached to the brush locking portions 3, 3. are fixed by welding, and in order to make both brushes 2, 2 plate-shaped, a stone is placed between the brushes 2 and 2.
A bonding agent 9 such as a silicone rubber compound is applied to the outer surfaces of both brushes 2, 2 except for the lower ends 2a, 2b, between the brushes 2, 2, and inside the brushes 2, 2 to prevent the brushes from slipping through the brushes 2, 2.

The channel type brush 2 has a large number of nylon brush bristles 5, 5, . It is crowned with 5,5 brush bristles...
...The width of the group is 12-13cm, the length is 7-8cm, and the depth is
It is 0.8-1.2cm. When two sets of the brushes 2 are stacked, the depth becomes 1.8 to 2.6 cm. With this thickness, you can reliably prevent the stones from slipping through.
If it is thicker than this, the repulsive force will become too strong, which will have a negative side. The brush 2 on the front of the auxiliary obstacle avoider 1 slightly protrudes in the direction of travel of the vehicle, and the cross section of the brush as a whole is approximately a parallelogram.

The brushes 2, 2 need to be made of a material that can withstand temperatures of about 100° C., since the car body lowers and comes into contact with the tracks in the case of a crowded train.

The fixture 4 also includes a base plate 8 having bolt holes 8a, 8a, and side walls 10, 1 vertically disposed on the base plate 8.
0, 10, and the brush locking brushes 3, 3 have their upper surfaces 3a, 3a in contact with the lower ends of the side walls 10, 10, 10a, 10a, and their side surfaces 3b,
3b is fixed to the fixture 4 so that the upper part thereof is in contact with the lower part of the substrate 8. Said side walls 10, 10...
Since the lower ends 10a, 10a... of are inclined,
When the fixture 4 is fixed to the vehicle's obstacle remover, the brush 2,
2 slopes inward.

The auxiliary evacuators 1 are used in pairs, and the embodiment shown in FIG. 1 is attached to the auxiliary evacuator on the left side of a vehicle.

〔effect〕

As mentioned above, the vehicle auxiliary obstacle remover according to the present invention eliminates the drawbacks of the conventional auxiliary obstacle remover made of a rubber plate, and has sufficient repulsive force to remove stones. On the other hand, it is characterized by a repulsion force that is not strong enough to send stones flying to houses near the railroad tracks. In addition, since the outer surface of the entire bristle bundle of the brush is coated with a binder, stones are not caught between the bristle bundles, and the above-mentioned effects of the brush are maintained for a long time.

In addition, since the auxiliary barrier of the present invention is flexible, it will not be damaged even if the vehicle body sinks and the auxiliary barrier comes into contact with the tracks, as in the case of a crowded train. The practical effects are significant.
