It is made to rotate. Further, the auxiliary wheels 2b, 2b sandwich the track R from both sides to prevent the drive wheel 2a from coming off the track R.

The vertical rotating shaft 2C protrudes vertically upward from the running wheel portion 2, and the blower is rotated by the driving force of the power portion 1a to suck outside air, and the air is sucked in through the filters 3a, 3a. A suction section 3 that exhausts air from an exhaust port 3b is arranged so as to be rotatable with respect to the traveling section 2, and a suction port body 4 connected to this suction section 3 is positioned at a side of this suction section 3. The main part of the vacuum cleaner main body 1 is arranged so as to be configured as shown in FIG.

The suction port body 4 has a horizontally elongated box shape with respect to the traveling direction, and the bottom surface of the suction port body 4 has a suction port 4a with a horizontally elongated opening directed toward the track R site surface RA. 4a is arranged. This suction port 4

The tip of the brush of this brush body 5 is made to substantially contact the site surface RA to which the track R is attached and the side surface RB of the track R. The brush body 5 is connected to the power section 1a via a reduction gear (not shown), etc., and the driving force of the power section 1a is used to sweep up cigarette butts, etc. toward the rear of the vacuum cleaner main body 1. The cigarette butts are rotated to fly up the cigarette butts and the like to the vicinity of the suction ports 4a, 4a.

Dust collecting filters 4g, 4g are installed inside the suction port body 4. Furthermore, this suction port body 4
Lids 4b, 4b are disposed on the upper surface of the suction port body 4 so that dust such as cigarette butts, etc., accumulated in the suction port body 4 can be removed by opening the lids 4b, 4b. An auxiliary suction port 4c is provided in a part of the lid 4b. In a normal state, this auxiliary suction port 4c is closed by a cap 4d. A locking hole 4e is provided at the upper end of the suction port body 4, and the hook 6a of the turning handle 6 fits into this locking hole 4.
It is locked on e.

The vacuum cleaner main body 1 is biased by a spring (not shown) provided near the vertical rotation shaft 2c, and is in the solid line position in FIG. 2 under normal conditions. By fitting and fixing the hook 6a of the turning handle 6 to the stopper 7a of the handle 7, the handle 7, the suction port body 4 of the main body 1,
The rotating handle 6 forms a substantially triangular shape, and the suction port body 4 is fixed at the solid line position in FIG.

Furthermore, both ends 4h of the suction port body 4
, 4h are provided with rubber skirts 4f, 4f for preventing scattering of cigarette butts etc. thrown up by the brush body 5, with the tips of the skirts 4f substantially touching the site surface RA.

An auxiliary suction hose 8 is attached to a part of the handle 7 by a band 9. The rear end of this auxiliary suction hose 8 has the auxiliary suction port 4c.
An engaging portion 8a that engages with is formed. Further, a stopper 7a for locking the turning handle 6 is provided in another part of the handle 7, and the turning handle 6 in a normal state is fixed to this stopper 7a.

Next, the operation of the track site cleaner according to the first embodiment of the present invention will be explained.

In this track site cleaner, the drive wheel 2a and the auxiliary wheel 2b of the running wheel section 2 are mounted on at least one track R, and the cleaner body 1 is installed on the track R. Next, when the power unit 1a is switched on and cleaning is started, the drive wheels 2a are driven and the cleaner main body 1 runs on the track. Since the speed of the drive wheel 2a can be switched in two stages,
You can select the travel speed that suits the cleaning time and area to be cleaned. While traveling, the driving force of the power unit 1a also rotates the blower of the suction unit 3, and cigarette butts etc. on the track R site are sucked in from the suction ports 4a, 4a provided at the opening of the suction port body 4. Suck it up within 4 hours. The sucked up cigarette butts etc. are captured by the filters 3a, 3a, and only the exhaust gas is sent to the exhaust port 3b.
from the vacuum cleaner body 1.

Further, brush bodies 5, 5 which rotate by the drive of the power unit 1a are disposed near the opening of the suction port body 4, so that cigarette butts, etc. are not deposited within the track R premises during cleaning. Even if the cigarette butts are attached, when the cigarette butts come close to the suction port body 4 while running, the brush bodies 5 will scrape up the cigarette butts, and the blower of the suction unit 3 can suck them up. Therefore, even if these wet cigarette butts and the like are stuck on the track R premises, they can be scraped up by the rotational force of the brush bodies 5, 5, and easily sucked up by the suction force of the blower. At this time, since rubber skirts 4f, 4f are extended on both sides of the side surface of the suction port body 4 so that their tips substantially contact the site surface RA, the brush body 5
This prevents flying cigarette butts, etc. from scattering. By limiting the cleaning (suction) range in this way, the suction efficiency is high,
Dust such as cigarette butts and butts can be sufficiently sucked out.

[0026] Since the suction ports 4a, 4a have a horizontally elongated shape, large crushed stones S, etc.
It will not be sucked up from a or 4a.

Furthermore, the turning handle 6 is moved to a stopper 7a.
When the main body 1 is removed from the main body and pulled backward, the main body 1 rotates about the vertical rotation axis 2c in the direction shown by the arrow against the biasing force of the spring. Therefore, even if there is an obstacle X within the premises of the track R, the suction port body 4 can be rotated to the position indicated by the two-dot chain line in FIG. 2 so as not to collide with the obstacle X. Due to this rotation, the suction port body 4 can perform continuous cleaning without colliding with the obstacle X even if the cleaner main body 1 runs on the track R as it is. After passing the obstacle X, when the hand is released from the turning handle 6, the suction port body 4 returns to the position indicated by the solid line in FIG. 2 due to the biasing force of the spring. Then, by locking the turning handle 6 to the stopper 7a again to fix the rotation of the suction port body 4, there is no possibility that the position of the suction port body 4 will rotate against the user's will.

Furthermore, for areas that cannot be cleaned with the suction port body 4, remove the auxiliary suction hose 8 from the bands 9, 9, and connect the engaging portion 8a of the auxiliary suction hose 8 with the cap 4d. The suction port body 4 can be extended by connecting it to the auxiliary suction port 4c that has been removed and opened. Therefore, cigarette butts and the like hidden behind various obstacles can be sucked up using the auxiliary suction hose 8. At this time, a mechanism for closing the suction port 4a side of the suction port body 4 is arranged at the suction port 4a,
The suction force on the auxiliary suction hose 8 side may be further improved.

After cleaning, the lid 4b installed on the top surface of the suction port body 4 is opened, and the sucked up dust such as cigarette butts is taken out together with the dust collecting filters 4g and 4g, and the work is completed.

[0030] In the first embodiment of the track site vacuum cleaner,
Furthermore, since the structure is configured as described above, even if the cleaner body 1 is traveling forward, the suction port body 4 can be rotated to the rear of the cleaner body 1. Therefore, even if you have passed a place once, you can rotate the suction opening body 4 again and return it without stopping the movement of the cleaner body 1.
It can be passed over areas where cigarette butts, etc. remain to clean them. Therefore, the cleaning efficiency is higher than that of a vacuum cleaner that simply sucks while moving. Furthermore, since the same power section 1a is used to drive the drive wheels 2a, the blower of the suction section 3, and the rotation of the brush body 5, it is small and lightweight, and even one person can easily carry out the cleaning work. In addition, since it does not require much storage space after the work is completed, it can be used even at stations with limited space.

[0031] In the track site cleaner of the first embodiment, the drive wheel 2a of the running wheel section 2 is connected to the power section 1a,
Although it is designed to be driven, the handle 7 is not connected to the power section 1a and is rotatable from the rear of the vacuum cleaner main body 1.
You may also be able to run freely by pressing .

Furthermore, the vacuum cleaner main body 1 is attached to the running wheel portion 2.
In addition to rotational movement around the vertical rotation axis 2c, a connection structure is disposed between the vacuum cleaner main body 1 and the running wheel portion 2 that can swing left and right with respect to the traveling direction, and the suction opening body Both end portions 4h, 4h of 4 may be vertically movable with respect to the site surface RA. In this way, both ends 4h of the suction port body 4
, 4h can be moved up and down with respect to the site surface RA, even if the site surface RA is lower on one side of the track R, the cleaner body 1 can be tilted and the tip of the rubber skirt 4f can be moved up and down to the site surface RA. The cleaning effect can be further improved.

[0033]The base end portion 4 of the suction port bodies 4, 4
A retractable hollow body such as a bellows may be disposed between i, 4i and the suction part 3 so that the suction opening bodies 4, 4 can be extended.

FIGS. 4 and 5 show a track cleaner according to a second embodiment of the present invention.

The same parts as those of the first embodiment of the track site cleaner will be described with the same reference numerals.

[0036] In the track site vacuum cleaner of this second embodiment,
A suction port body 4 is protruded from only one side of the cleaner body 1. On the opposite side of the vacuum cleaner body 1 to the side where the suction port body 4 is disposed, there is an auxiliary wheel support bar 10 that straddles between the tracks R1 and R2 and has an auxiliary wheel 11 at its tip. It has been extended. A handle 7 is disposed approximately at the center of the auxiliary wheel support bar 10 toward the rear of the device main body 1. The auxiliary wheel 11a of the auxiliary wheel portion 11 has a trajectory R2.
It is mounted above the wheel and can rotate freely. Also, the training wheel 11
b, 11b sandwich the track R2 from both sides, and the auxiliary wheels 1
1a is prevented from coming off the track R2.

In the track area cleaner of the second embodiment constructed in this manner, in addition to the effects of the first embodiment, the suction port 4 may be provided protruding only on one side of the cleaner body 1. , the auxiliary wheel support rod 11 disposed on the opposite side to the protruding side of the suction port body 4 straddles the tracks R1 and R2, and the auxiliary wheel 11
a, 11b, 11b are mounted on the track R2, so the center of gravity of the vacuum cleaner body 1 can be set between the tracks R1, R2, and even if the handle 7 is released, the suction mouth body 4 will not protrude. It will not fall on the side where it is installed.

Furthermore, since the suction port body 4 is disposed only on one side of the cleaner body 1, it is possible to further reduce the size and weight compared to the orbital site cleaner of the first embodiment. .

[0039] In the track site vacuum cleaner of this second embodiment,
The auxiliary wheel 11a of the auxiliary wheel section 11 is mounted above the track R2 and is rotatable, but like the drive wheel 2a, it is connected to the power section 1a by an existing method via a reduction gear, a transmission shaft, etc. , and may be driven at substantially the same speed as the drive wheels 2a.

Further, the auxiliary wheels 2b of the running wheel section 2 and the auxiliary wheels 11b of the auxiliary wheel section 11 are arranged so as to sandwich the side surfaces of the tracks R1 and R2 from both sides, but the present invention is not limited to this. If the configuration is such that the wheels 2a and auxiliary wheels 11a do not come off the tracks R1 and R2, the auxiliary wheels can be brought into contact only with the inner surfaces of the tracks R1 and R2 facing each other, and a plurality of these auxiliary wheels can be arranged across the front and rear directions. Any configuration may be used.
