Description

[Detailed description of the invention] This invention is a rectangular mole car that is equipped with rubber tires and runs on the upper surface of the girder.The tire abrasion powder accumulated and solidified on the tire tread is detected by a tire inspection device. The present invention relates to a device for automatically removing deposits on tire treads.

Traditionally, in mole railcars that use rubber tires, tire abrasion powder is generated due to slipping during braking, starting, and running on curves, and this powder is trampled by the following tires and becomes deposits on the tire tread. .

When a tire travels back and forth over a certain section many times, this deposit accumulates, and as the accumulation progresses, it becomes a solid substance, forming bands or localized bulges that match the pattern of the tire tread, increasing tire running noise. is the current situation.

Conventionally, there is no device for removing the adhering particles of tire wear powder, and the actual situation is that the adhering substances are scattered outside by centrifugal force due to local deformation of the tire tread surface due to driving.

For this reason, it is desired to improve the causes of dust and noise caused by tire wear particles.

The purpose of this invention is to automatically remove the deposits on the tire tread, and the roller of the tire drive device has unevenness that only locally deforms the tire tread without damaging or peeling off the tire tread. A roller having a tooth profile (hereinafter referred to as a scraper) is provided,
By pressing this when inspecting a tire, the tread surface of the tire is forcibly deformed locally and the adhesion is removed.

Next, the present invention will be explained based on the drawings.

Figure 1 is a side view showing the appearance of the constellation mole car, Figure 2
．． FIG. 3 is a side view and a front view of an embodiment of the tire tread surface deposit removal device according to the present invention.

A car body 1 of a mole rail car runs at high speed on a track girder 3 via a two-shaft bogie type bogie 2, and pneumatic rubber tires 4 are driven by the power of an electric motor.

Guide tires 5 are provided on the sides of the track girder 3 to ensure stable running against left and right movements.

For example, a cylinder 7.7' (either hydraulic or pneumatic) and a motor 8 are attached to an inspection girder 6 installed in a garage, and a driving roller 9 is attached to the tip of one cylinder 7, and a driving roller 9 is attached to the tip of the other cylinder 71. A roller-type scraper 10 having high and low teeth set at irregular intervals is installed.

A telescopic professional shaft 1 is located between the motor 8 and the driving roller 9.
1 is attached, and the power of the motor 8 drives the roller 9 through a drive device 12 equipped with a professional shaft 11 and a power direction changer.

Now, when the vehicle 1 and the rubber tires 4 are stopped on the inspection girder 6 and the cylinder 7 presses the rollers 9 against the rubber tires 4 and the motor 8 is rotated, the rollers 9 are rotated by the power, and the rubber tires 4 are also rotated accordingly.

At this time, the cylinder 71 is activated by another command and the scraper 1 is
0 with a pressure of Pl that does not damage the tire tread but deforms it, the solidified adhesion 13 of tire abrasion powder and concrete girder abrasion powder adhering to the rubber tire 4 can be removed. Can be done.

As another plan, although not shown, the inspection girder 6 is not provided with the motor 8, the scraper 10 is lifted up by the cylinder 71 and brought into contact with the rubber tire 4, and the rubber tire 4 is rotated by the electric motor of the mole rail truck itself. Tire tread deposits can also be removed.

The tire tread deposits are removed by adjusting the pressing force of the scraper 10 to scrape them off with uneven teeth shaped at irregular intervals, with the unevenness having different heights.

The direction of rotation of this rubber tire 4 is repeated in forward and reverse directions,
Furthermore, if the inspection girder is passed through a separate inspection girder removal device in which the rotation direction of the roller 9 is different, the removal effect will be greater.

Another embodiment of the invention is shown in FIG.

The rubber tire 4 with deposits on it is driven and supported by a driving roller 9 and a holding roller 91.

If the scraper or brushing roller 14 is brought into contact with the rubber tire 4 through the cylinder 7'', the deposits can be removed in the same manner as described above.

By using the deposit removal device of the present invention, it is easy to remove deposits, there is no phenomenon of tire deposits falling from the girder, and running noise can be reduced to a constant value, preventing vehicle vibrations and when starting and braking. This has the effect of reducing slippage.

Note that there is no need for any particular regulation regarding the uneven teeth of the scraper, whether square or pointed.

Furthermore, the removal efficiency can be increased by providing the high and low teeth in the cross-sectional direction.
