[0004]
[Means for Solving the Problems]
In order to solve the above problems, the overhead wire support insulator cleaning device according to the present invention,
An overhead wire supporting insulator cleaning device for cleaning a plurality of overhead wire supporting insulators arranged along a track, wherein the large diameter portion and the small diameter portion are alternately adjacent to each other in a direction intersecting the track. A device,
A cleaning member that can be inserted into the small diameter portion from a radially outer side of the small diameter portion,
A drive mechanism for inserting the cleaning member into the small-diameter portion and moving the cleaning member along an outer-diameter portion of the small-diameter portion is provided.
[0005]
The operation and effects of the overhead wire supporting insulator cleaning device having this configuration are as follows.
First, many insulators are arranged along the tracks of monorails and trains. The large-diameter portion and the small-diameter portion are attached alternately adjacent to each other in a direction intersecting the track. A cleaning member is provided, and is configured to be insertable into the small diameter portion from a radially outer side of the small diameter portion. A drive mechanism for moving the cleaning member is provided, the cleaning member is inserted into the small diameter portion, and the cleaning member is further moved along the outer diameter portion of the small diameter portion. Thereby, the overhead wire support insulator can be cleaned by the cleaning member. As a result, it is possible to provide an overhead wire support insulator cleaning device capable of reducing the labor of an operator required for cleaning the overhead wire support insulator.
[0006]
As a preferred embodiment of the present invention, the cleaning member is a cleaning brush, a first cleaning brush that can be inserted into the small-diameter portion from the left side, and a cleaning brush that can be inserted into the small-diameter portion from the right side when viewed in a direction intersecting the track. And a possible second cleaning brush.
[0007]
A cleaning brush is used as the cleaning member, and includes the first cleaning brush and the second cleaning brush as described above. The first cleaning brush is inserted into the small diameter portion from the left side, and the second cleaning brush is inserted into the small diameter portion from the right side. Therefore, the range in which cleaning is performed by the cleaning brush can be shared, and cleaning can be performed efficiently.
[0008]
As another preferred embodiment of the present invention, the cleaning member is configured to be switchable between a cleaning posture for performing cleaning and a standby posture in which cleaning is not performed, and is arranged along a track in the standby posture. And a structure that can move in a direction intersecting with the track while avoiding an overhead wire.
[0009]
When starting the cleaning operation by the cleaning member, it is necessary to move the cleaning member from the outside in the direction intersecting the track to the direction in which the insulator is provided. In this case, since the overhead wire is laid along the track, the cleaning member must be moved so that the cleaning member does not interfere with the overhead wire. Therefore, by configuring the posture of the cleaning member to be switchable between the cleaning posture and the standby posture, the cleaning by the cleaning member can be started smoothly.
[0010]
As still another preferred embodiment of the present invention, the cleaning brush includes a fulcrum portion, a brush portion, and an elastic deformation portion connecting the fulcrum portion and the brush portion, and the cleaning brush is attached to the small-diameter portion. When the cleaning brush is ejected after the cleaning brush is inserted, the elastic deformation portion is deformed when the cleaning brush is inserted, so that the brush portion in the cleaning posture is caused to press against the small diameter portion, and the cleaning brush is operated. At the time of escape, the structure may be configured to return to the original washing posture by the elastic restoring force of the elastic deformation portion.
[0011]
According to this configuration, the cleaning brush has the fulcrum portion, the brush portion, and the elastic deformation portion. When the cleaning brush is inserted into the small diameter portion, the elastically deforming portion is deformed, and the brush portion is pressed against the small diameter portion. The cleaning effect can be enhanced by the pressing by the brush portion. After the cleaning brush escapes from the small diameter portion, the cleaning brush returns to the original posture by the elastic restoring force of the elastically deforming portion. Therefore, the mechanism for performing the cleaning can be simplified.
[0012]
As still another preferred embodiment of the present invention, a sensor provided with a sensor for detecting the position of the insulator is provided.
[0013]
A large number of insulators are arranged along the track, and it takes a great deal of effort to find them by visual inspection of an operator. Therefore, by providing a sensor for detecting the position of the insulator, the insulator can be easily found, and the cleaning operation can be performed efficiently.
[0014]

[0018]
FIG. 4 is an enlarged view showing details of the cleaning brush 7 of the cleaning device 5. FIG. 5 is a side view showing the cleaning device 5 in detail. FIG. 6 is a diagram showing a driving mechanism for driving the cleaning brush 7.
[0019]
FIG. 4 illustrates the configuration of the cleaning brush 7 and the operation of the cleaning brush 7. In a first direction, the cleaning brush 7 includes a first cleaning brush 7A and a second cleaning brush 7B. The first cleaning brush 7A cleans the upper half of the insulator 5, and the second cleaning brush 7B cleans the lower half of the insulator 5. Although only one cleaning brush 7A, 7B is seen in a plan view of FIG. 4, as can be seen from a side view of FIG. 5, three first cleaning brushes 7A and three second cleaning brushes 7B are provided. Have been. This is provided with three insulators 5 corresponding to the shape of the insulator 5 (see FIG. 3). Note that the number of cleaning brushes 7 is not limited to a specific numerical value, but can be set arbitrarily. Although the material of the cleaning brush 7 is not particularly limited, for example, nylon-based resin fibers can be used.
[0020]
Here, the configuration of the cleaning brush 7 will be described. The cleaning brush 7 includes a fulcrum part 70, a brush part 71, and an elastic deformation part 72 connecting the fulcrum part 70 and the brush part 71. The fulcrum 70 is rotatable around a rotation center 70a. Therefore, the cleaning brush 7 itself can rotate around the rotation center 70a. Specifically, the cleaning brush 7 can be switched between a standby posture and a cleaning posture. The standby posture is indicated by reference numerals 7A ″ and 7B ″ in FIG. 4, and the cleaning brush 7 is in the horizontal posture. This horizontal posture is a posture that does not interfere with the aluminum gantry 9 and the trolley wire 10 even when the cleaning brush 7 is moved along the first direction. In the cleaning posture, the cleaning brush 7 is in a vertical posture, the tip of the first cleaning brush 7A is downward, and the tip of the second cleaning brush 7B is upward.
[0021]
The elastically deforming portion 72 is formed of, for example, a tightly wound coil spring, and can change the posture of the brush portion 71 in the cleaning posture. In FIG. 4, when the first cleaning brush 7A moves from the left side to the right side (indicated by an arrow B, hereinafter referred to as a “second direction”), the second cleaning brush 7B moves from the right side to the left side ( (Indicated by an arrow C, hereinafter referred to as “third direction”). Conversely, when the first cleaning brush 7A moves in the third direction, the second cleaning brush 7B moves in the second direction in conjunction with this movement. When the first cleaning brush 7A is at the position indicated by the solid line in FIG. 4 and then moved in the second direction by the drive mechanism to perform the cleaning action, the first cleaning brush 7A moves from the radially outer side of the small diameter portion 5b to the small diameter portion 5b. Is inserted. The first cleaning brush 7A is deformed by the contact with the small diameter portion 5b. Thereby, the pressing force by the brush part 71 acts on the small diameter part 5b and the large diameter part 5a, and the cleaning effect is enhanced. When the first cleaning brush 7A further moves in the second direction, the first cleaning brush 7A moves along the outer diameter portion of the small diameter portion 5b and escapes from the small diameter portion 5b. With the escape, the first cleaning brush 7A returns to the original cleaning posture by the elastic restoring force of the elastic deformation portion 72 (indicated by reference numeral 7A '). At the time of automatic restoration by the elastic restoring force, the brush portion 71 has an effect of removing dirt by swinging and swinging. The above operation is the same for the second cleaning brush 7B.
[0022]
By repeating the cleaning operation by the cleaning brush 7, the tip portion of the brush portion 71 is significantly worn and deformed. By attaching a buffer resin or the like to the tip of the brush portion 71, the abrasion of the brush portion 71 can be prevented. .
[0023]
Next, a drive mechanism for driving the cleaning brush 7 will be described with reference to FIG. The drive mechanism includes a cylinder 11 as a drive source, a first rack gear 12 connected to a rod 11a of the cylinder 11, a pinion gear 13 meshing with the first rack gear 12, and a second rack gear 14 meshing with the pinion gear 13. . Therefore, by moving the rod 11a in and out of the directions of arrows B and C, the first and second rack gears 12 and 14 are driven in conjunction with each other, and the first and second cleaning brushes 7A and 7B are moved in conjunction with each other. it can.
[0024]
As shown in FIG. 5, a guide mechanism 15 for guiding the first rack gear 12 and a guide mechanism 16 for guiding the second rack gear 14 are provided. As described above, the brush part 71 of the cleaning brush 7 is attached to the fulcrum part 70 (see FIG. 4), and this fulcrum part 70 is further supported by the support 18. The support 18 and the first and second rack gears 12 and 14 are integrally connected. Further, the fulcrum 70 is rotatable around the rotation center 70a with respect to the support 18, but a rotation drive mechanism (not shown) for rotating the fulcrum 70 is provided.
[0025]
Further, a drive mechanism (not shown) for vertically moving the entire cleaning device 4 is provided, and a guide mechanism 17 therefor is also provided. The mechanism for moving the cleaning device 4 up and down is provided because the mounting height of the insulator 5 is not all the same, but is changed depending on the location.
[0026]
<Cleaning procedure>
Next, a procedure for cleaning the insulator using the cleaning device 4 will be described. The cleaning vehicle equipped with the cleaning device 4 is moved along the rail 2 to detect the position of the insulator 5, and the cleaning device 4 is driven at each position of the insulator 5 to perform a cleaning operation. At the start of the cleaning operation, the cleaning brush 7 is in a standby posture. In this case, as shown on the right side of FIG. 1, the cleaning device 4 is on standby outside the overhead line. Next, the cleaning device 4 is driven along the first direction. Since the cleaning brush 7 is in the standby posture, the cleaning brush 7 can move in the first direction without interfering with the aluminum gantry 9 and the trolley wire 10.
[0027]
Next, the cleaning brush 7 is switched from the standby posture to the cleaning posture. As a result, a posture in which the washing operation can be performed at any time is prepared.
[0028]
The cleaning truck 1 includes a sensor that detects the position of the insulator 5. This sensor is, for example, an image sensor or a photoelectric sensor, and can detect the presence of the insulator 5. Accordingly, the position of the insulator 5 is detected by the sensor while the cleaning car 1 is running, and when the insulator 5 is found, the cleaning car 1 is stopped there. With the cleaning car 1 stopped, the cleaning brush 7 is in a positional relationship as shown in FIG. Next, the first and second cleaning brushes 7A and 7B are moved in the directions of arrows B and C by the driving mechanism, respectively. Thus, the cleaning operation of the insulator 5 at the position where the cleaning car 1 has stopped is completed. A cleaning liquid for cleaning is provided in a tank provided at an appropriate place and stored therein, and the cleaning liquid is supplied in conjunction with the movement of the cleaning brush 7. Note that dry cleaning without supplying a cleaning liquid may be employed. How many times the cleaning brush 7 is moved by one insulator 5 can be appropriately set. For example, in FIG. 4, the first and second cleaning brushes 7A and 7B may be moved in the B and C directions, respectively, to complete cleaning of one insulator 5. You may make several round trips.
[0029]
When the operation of cleaning the insulator 5 at a certain place is completed and the operation proceeds to the next operation of cleaning the insulator 5, the posture of the cleaning brush 7 can be moved while maintaining the cleaning posture. At this time, one of the first cleaning brush 7A and the second cleaning brush 7B gets over the insulator 5 which has just finished the cleaning operation. As described above, the cleaning brush 7 has the elastic deformation portion 72. Because it can be deformed, there is no problem even if it gets over. As described above, the insulators 5 can be sequentially washed while moving the cleaning car 1 along the track.
<Another embodiment>
7 and 8 are views showing another embodiment. This embodiment differs from the embodiment shown in FIG. 4 in that the first cleaning brushes 7A and the second cleaning brushes 7B are arranged in two rows in the first direction. Of course, three or more rows can be provided. Except for the two rows, they have the same functions as those in FIG. FIG. 8 is a plan view of the cleaning brush 7 shown in FIG. Three cleaning brushes 7 are arranged along the first direction. This is because the insulator 5 has three small-diameter portions 5b. Further, the size of the cleaning brush 7 can be set according to the size of the insulator 5.
[0030]
<Other embodiments>
(1) The overhead wire supporting insulator cleaning device according to the present invention can be applied to the case of a train insulator other than the monorail.
(2) In this embodiment, as shown in FIG. 4, the first cleaning brush is moved from the left side (right side) to the right side (left side), and the second cleaning brush is moved in the opposite direction. It is not done. For example, as shown in FIG. 9, both the first cleaning brush 7A and the second cleaning brush 7B may be simultaneously moved in the same direction. In this case, the first cleaning brush 7A and the second cleaning brush 7B are arranged slightly shifted so that the movement is smooth.
