Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an escalator cleaning device that primarily cleans the tread portion of an escalator.

<Prior Art> As is well known, countless narrow grooves are formed on the upper surface of each tread of an escalator along the ascending and descending direction. For this reason, initially, when cleaning the top surface of this tread,
Workers were manually cleaning the grooves using small toothbrush-like brushes and thin sticks.

However, if workers manually cleaned the tread using small brushes or sticks, the efficiency of the work was low, and it was difficult to thoroughly clean the inside of the grooves of the tread. Also, using a thin stick could cause damage.

Furthermore, using conventional cleaning tools does not allow workers to leave the escalator while it is being cleaned. Therefore, in order to clean the escalators in a building with a large number of escalators, such as a department store, it is difficult to clean all the escalators without the labor of many workers and a long period of time. Ta. For this reason, the cleaning of escalators has become neglected even in department stores.

For this reason, there are some devices that clean the inside of escalator grooves by placing a flexible brush along them, and others that use flexible brushes to clean the inside of the grooves by rotating the brush to actively remove dust from inside the grooves. Various escalator cleaning devices have been proposed that use suction devices to collect dust, and escalator cleaning devices that actively rotate brushes to sweep out and suction dust from grooves are highly effective. The inside of the groove can be cleaned.

<Problems to be Solved by the Invention> However, the escalator cleaning device that rotates the brush may have the disadvantage that the cleaning device itself moves back and forth due to the rotational force of the brush. For this reason, it is necessary to arrange the cleaning device so that the vertical direction of the escalator tread and the rotating direction of the brush are opposite to each other, or to provide a strong stopper mechanism to hold the cleaning device in a fixed position, or to reduce the rotational force of the brush. In this case, the main body must be extremely heavy so that it does not move, and the cleaning device is not easy to handle, making it difficult for one worker to handle multiple cleaning devices at the same time.

In addition, since a cleaning brush cannot be installed in the part that provides the rotational driving force to rotate the brush, it becomes impossible to clean that part, resulting in a rough cleaning finish or incomplete cleaning. There is also the disadvantage that it is not possible to achieve good labor savings because cleaning of the parts that could have been done has to be done twice.

In view of the above, there has been a desire to develop a brush-rotating escalator cleaning device that is easy to handle and does not have any parts that cannot be cleaned in one cleaning.

<Means for Solving the Problems> The present invention was developed in view of the above, and has two support rods 3, which have parts 2 at both left and right ends and whose lengths are adjustable, and are arranged almost parallel to each other. A main body is provided at the lower part of the vertical member 4 extending downward from the support rod, and a box-shaped main body cover 8 which is elongated in the length direction of the support rod and has an open bottom is formed at the lower part of the main body, A pair of substantially parallel brush rolls 9 rotated by the drive of the motor 7 are placed inside the main body cover along the longitudinal direction of the main body cover with the lower ends of the brush rolls protruding downward from the lower opening 10 of the main body cover. A long inlet of a dust collection member (for example, a dust collection box 12) connected to the intake port 19 side of an intake machine 18 which is supported by a shaft and is provided with a filter is opened between both brush rolls within the main body cover, and , each driving force transmission mechanism section provided on each brush roll for transmitting rotational driving force to each brush roll (for example, a speed reducer 15)
are unevenly distributed so that they do not coexist in the vertical plane perpendicular to the rotation axis of the brush roll, and the brushes of both brush rolls are rotated in the direction of rotation from below to the inlet of the dust collection member, and the rotational force is approximately equal. is transmitted from each driving force transmission mechanism section to the brush roll.

<Operation> The cleaning device is placed on the tread of the escalator located closest to the floor surface, and the support rod is extended to press the left and right end parts against the inner surface of the lower part of the escalator. After fixing the cleaning device to the escalator in this way, the motor of the cleaning device is activated, and
When the escalator is operated, the brush roll rotates and enters the groove formed on the top of the tread.
Sweep away any dirt that has adhered to it. In addition, the rotation directions of the brush rolls are rotated so that they are opposite to each other, and
The dirt swept from the grooves by each brush roll is guided to the vicinity of the intake port of the dust collecting member. The dirt released from the footboard in this manner is sucked into the suction machine through the pipe from the inlet of the dust collecting member opened in the main body cover, and is collected in the filter.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

The cleaning device 1 has parts 2, 2 made of sponge, rubber, etc. at both left and right ends, and two support rods 3 whose lengths are adjustable are arranged approximately parallel to each other. A main body 5 is provided at the bottom of the vertical members 4, 4 to which are fixed. In order to make the length of the support rod 3 adjustable, in the embodiment shown in the drawings, a male screw 6a and a female screw 6b are screwed together in the middle of the support rod 3 near the end. The overall length of the support rod 3 can be adjusted by appropriately adjusting the length of the screw 6b. In addition, support rod 3
The structure for making the length adjustable is not limited to the above-mentioned embodiment, and any structure may be used as long as the length can be adjusted.

The main body 5, which is suspended from the support rod 3 through vertical members 4, 4, is made of plate material formed into a box shape, and a motor 7 for rotationally driving a brush roll, which will be described later, is located approximately in the center with the output shaft facing downward. A box-shaped body cover 8 is formed below the motor 7 and is elongated in the length direction of the support rod 3 and has an open bottom. A pair of substantially parallel brush rolls 9, 9 are placed inside the main body cover 8 along the longitudinal direction of the main body cover 8 with the lower ends of each brush roll 9 protruding downward from the lower opening 10 of the main body cover 8. At the same time, a roller 11 is pivotally supported on the outside of each brush roll 9 as a vertical position setting member, and a long dust collection box 12 with an open bottom is placed between the brush rolls 9 as a dust collection member. Established as Note that the lower end of the opening of the dust collection box 12 is located at approximately the same height as the lower end of the roller 11, or slightly higher than that.

The brush roll 9 has a substantially cylindrical shape with a countless number of relatively hard bristles 14 planted on the circumferential surface of a shaft 13, and is rotatably supported by a bearing at an end or an intermediate portion of the shaft 13. A decelerator 15, which is a driving force transmission mechanism composed of a worm gear, a bevel gear, etc., is provided at a portion off the center of the shaft, and a pulley attached to the input shaft of the decelerator 15 is attached to the output shaft of the motor 7 described above. A transmission belt 15' is stretched between the pulley and the motor 7 side. Note that the rotational force transmitted to each brush roll 9, 9 by each decelerator 15, 15 is approximately equal.

Therefore, the decelerator 15 of one brush roll 9
The position of the decelerator 15 of the other brush roll 9 is different from the position of the decelerator 15 of the other brush roll 9, as shown in FIGS. 3 and 4. In other words, by unevenly distributing both decelerators 15 and 15 so that they do not coexist in the vertical plane perpendicular to the rotation axis of the brush roll 9, the portion left unswept by one brush roll 9 (where the decelerator 15 is disposed) is removed. By providing the brush roll 9, the other brush roll 9 can sweep the portions where the bristles 14 could not be implanted, thereby eliminating the portions left unswept.

The roller 11 is arranged on the outside of each brush roll 9 and substantially parallel to the brush roll 9, and has a lower end of the outer peripheral surface lower than the edge of the opening 10 of the main body cover 8, and a brush protruding from the opening 10. roll 9
The hair is positioned higher than the lower end of the hair. Note that this roller 11 is desirably configured so that its height can be adjusted by, for example, making the bearing movable up and down.

Connection ports 16, 16 communicating with the dust collection box 12 are provided on the top surface of the main body cover 8 provided with the brush roll 9, roller 11, and dust collection box 12, and each connection port 16 is connected to a flexible pipe or the like. Connect one end of the pipe 17 and connect both pipes 17, 17.
After merging the other ends, the ends are connected to the intake port 19 of the intake machine 18. This suction machine 18 may have a filter and a fan inside and a function of collecting dust and the like sucked in together with the air in the filter, and may be, for example, a vacuum cleaner as shown in FIG. 1. Further, this suction machine 18 may be incorporated into the cleaning device 1.

To clean the escalator treads 20 using the cleaning device 1 configured as described above, the cleaning device 1 is placed on a trolley or the like and transported to the top (or bottom) of the escalator, as shown in FIG. As shown in , it is placed on the escalator tread 20 closest to the floor, the support rod 3 is extended, and the left and right ends 2, 2 are pressed against the lower inner surface 21 of the handrail portion of the escalator. When the cleaning device 1 is placed and fixed on the tread plate 20 of the escalator in this manner, the lower end of the roller 11 is connected to the groove 21 of the tread plate 20...
Since the brush rolls 9, 9 are supported by their upper edges, the height of the brush rolls 9, 9 is determined by this, and only the tips of the brushes that protrude downward from the lower end of the rollers 11 are in the grooves 2 of the tread plate 20.
1...Go inside. That is, when the position of the roller 11 is set high, the length of the bristles that protrude downward from the lower end of the roller 11 becomes longer, which causes the tread plate 2
0 groove 21...The length of the hair tip that enters into the groove 21 increases. On the other hand, if the roller 11 is set low,
The length of the bristles that protrude downward from the lower end of the roller 11 becomes shorter, thereby reducing the length of the bristles that enter the grooves 21 of the treadle 20. Therefore,
By adjusting the height of the roller 11, the tread plate 2
The length of the bristles of the brush rolls 9, 9 that enter into the grooves 21 of 0 can be adjusted as appropriate, so that the dirt adhering to the grooves 21 can be swept out most efficiently, and the brush rolls 9, You can set it so as not to damage the tips of your hair.

When the motor 7 of the cleaning device 1 is operated in the above-described state, the brush rolls 9, 9 move in the direction of the arrow in FIG. Then, the bristles rotate at a speed faster than the moving speed of the escalator, and the countless bristles evenly sweep the upper surface of the tread 20, especially the inside of the grooves 21, and scrape out the adhered dirt toward the opening of the dust collection box 12. The sand that was scraped out in this way,
Dirt, dust, and other contaminants are effectively guided to the inlet opened at the bottom of the dust collection box 12, sucked into the dust collection box 12, and then conveyed to the intake machine 18 through the pipe 17. The air is separated from the air by the filter of the intake machine 18 and accumulated in the filter. Then, when the escalator motor is operated, each step board 20 comes under the main body cover 8 one after another, so the upper surface of all the step boards 20 can be cleaned while the cleaning device 1 remains fixed.

Further, since the pair of brush rolls 9, 9 arranged approximately parallel to each other rotate in opposite directions, the force generated by the sliding of each brush roll 9, 9 and the escalator tread 20 (cleaning device 1 The force that tries to move the cleaning device 1 back and forth is canceled out, and in order to hold the cleaning device 1 in a predetermined position,
A force sufficient to resist the lifting force of the escalator tread 20 is sufficient. In other words, as mentioned above, the support rod 3
By extending the parts 2, 2 on both the left and right ends and pressing them against the lower inner surface 21 of the handrail part of the escalator, the main body of the cleaning device 1 can be well held in a predetermined position on the escalator, and there is no need for an operator. Cleaning work can also be continued. Moreover, since there is no need to provide a complicated and strong stopper mechanism for fixing the main body of the cleaning device 1 or to make the main body of the device extremely heavy, one worker can operate multiple cleaning devices 1... By cleaning multiple escalators in parallel, extremely efficient escalator cleaning can be achieved. Further, according to the cleaning device 1 according to the present invention, there is no need to consider the rotating direction of the brush roll 9 according to the ascending and descending direction of the escalator, so it can be used at either the upper or lower ends of an ascending escalator or the upper and lower ends of a descending escalator. It is.

In addition, in the present invention, a skirt 22 made of an elastic material such as a synthetic rubber plate is provided to surround the opening of the main body cover 8, so that when the main body cover 8 is placed on the tread 20 of an escalator, the opening and the tread 20 may be reduced as much as possible.

Further, the vertical position setting member is the roller 1 described above.
1, when the body cover 8 is placed on the tread plate 20, the height of the brush roll 9 is set to maintain an appropriate length of the bristles that enter into the grooves 21 of the tread plate 20. Any structure may be used as long as it has a function, such as a horizontally long plate or bar.

<Effect of the invention> As explained above, according to the invention, the elongated inlet of the dust collecting member is opened between a pair of substantially parallel brush rolls, and the brushes of both brush rolls collect dust from below. Since the brush rotates in the direction leading to the entrance of the member, extremely effective dust collection is achieved by guiding the dust swept by the brush from the countless grooves formed on the top surface of the escalator tread to the opening of the dust collecting member. I can do it.

In addition, the driving force transmitting mechanism unit that transmits the rotational driving force to both brush rolls is unevenly distributed so that it does not coexist in the vertical plane perpendicular to the rotation axis of the brush rolls, so the driving force transmitting mechanism unit is provided. As a result, areas where it is impossible to install brushes can be compensated for by the other brush roll. That is, by eliminating parts that cannot be cleaned in one cleaning, cleaning efficiency can be improved and good cleaning can be expected.

Furthermore, since both brush rolls are rotated in opposite directions with approximately equal rotational force, the forces generated by the sliding of the brushes and the escalator tread are canceled out, and the support rods and pads can be used relatively easily. It becomes possible to fix the main body of the device on the escalator. Therefore, handling of the escalator cleaning device is extremely simple, and one worker can operate multiple escalator cleaning devices at the same time.
Multiple escalators can be cleaned, resulting in significant labor savings.
