Description

  The present invention relates to a road post cleaning device for cleaning an outer peripheral surface of a road post.

  Conventionally, as this kind of road post cleaning device, for example, one disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 9-125323) is known. As shown in FIG. 13, the road column cleaning device Sa includes a substantially cylindrical main body member 100 whose both ends are open, and an operation member provided on the main body member 100 so as to be movable in the longitudinal direction of the road column Pa. 110, and one end fixed to the operation member 110 and the other end fixed to the lower end side of the main body member 100, and a substantially coil-like shape that can be expanded and contracted disposed in a space formed by the road column Pa and the main body member 100. The brush member 120 is provided.

  When the road column Pa is cleaned using the cleaning device Sa, the operator first inserts the main body member 100 into the road column Pa with the operation member 110 pushed in. When the main body member 100 is inserted, the tip of the brush of the brush member 120 contacts the outer peripheral surface of the road column Pa. Next, the operating member 110 is moved up and down by the operator's hand. When the operating member 110 is raised, the brush member 120 extends along with the operating member 110 while rotating around the outer peripheral surface of the road column Pa, and when the operating member 110 is lowered, the brush member 120 rotates around the outer peripheral surface of the road column Pa. It shrinks together with the operation member 110. As a result, the brush member 120 rubs the outer peripheral surface of the road column Pa, so that the dirt attached to the outer peripheral surface of the road column Pa can be removed, and the road column Pa can be cleaned.

JP-A-9-125323

  However, in this conventional road column cleaning device Sa, the operator conveys the main body member 100 to the road column Pa and passes through the road column Pa, and the operator manually inserts the operation member 110 by hand. Since the brush member 120 is moved up and down by raising and lowering, there is a problem that the work of cleaning the outer peripheral surface of the road column Pa is complicated.

  The present invention has been made in view of such a problem, and enables the brush member to be easily transported and attached to the road column, and after the application, the brush member is attached to the road column. An object of the present invention is to provide a road post cleaning device that can automatically rub the outer peripheral surface of the road and improve the workability of the road post cleaning work.

  In order to achieve such an object, the road strut cleaning apparatus of the present invention is an internal structure that is inserted into the strut and rotated about an axis in the road strut cleaning apparatus for cleaning the outer peripheral surface of the road strut. A cylinder, a brush member attached to the inner wall surface of the inner cylinder and rubbing the outer peripheral surface of the support column by rotation of the inner cylinder, an outer cylinder surrounding the inner cylinder and rotatably supporting the inner cylinder, The driving unit is provided in the outer cylinder and rotates the inner cylinder, and a moving mechanism that moves the outer cylinder.

  Thereby, when cleaning the road column, first, the outer cylinder is moved above the road column by the moving mechanism. When the outer cylinder is moved, the inner cylinder and the drive unit are also moved. Then, the outer cylinder is moved downward by the moving mechanism, the inner cylinder is inserted through the road column, and the brush member is attached so as to contact the outer peripheral surface of the road column. Next, the drive unit is driven to rotate the inner cylinder around its axis. When the inner cylinder is rotated, the brush member attached to the inner wall surface of the inner cylinder also rotates in the same direction as the inner cylinder. Since the brush member is in contact with the outer circumferential surface of the road column, when the brush member rotates, the outer circumferential surface of the road column is rubbed by the brush member, and thereby, adheres to the outer circumferential surface of the road column. Dirt such as dirt can be scraped off and removed, and road posts can be cleaned.

  That is, since the outer cylinder is moved by the moving mechanism and the inner cylinder is rotated by the drive unit, the brush member can be easily transported and attached to the road column, and the rotation of the inner cylinder causes the road column to move. Since dirt such as dust can be scraped off and removed by rubbing the outer peripheral surface, it is possible to improve the workability of the cleaning work of the road column as compared with the conventional case. In addition, since the outer cylinder is provided surrounding the inner cylinder, the inner cylinder rotating by the outer cylinder cannot be touched, so that the operator is injured by the rotation of the inner cylinder, etc. Accidents can be prevented.

  Then, if necessary, a trumpet-shaped guide member is provided on the lower end side of the inner cylinder or the lower end side of the outer cylinder so as to gradually increase the diameter toward the lower side and guide the support column into the inner cylinder. . Thus, when the brush member is attached to the road column, even if the inner cylinder is located at a position slightly deviated from the road column, the upper part of the road column hits the guide member and is guided into the inner cylinder. The brush member can be attached to the road column by reliably inserting the inner cylinder into the road column. That is, since the inner cylinder can be easily inserted into the road column, the brush member can be easily attached to the road column.

  Further, if necessary, the brush member is assembled to a predetermined width along the rotation direction of the inner cylinder and to a predetermined length along the rotation axis direction of the inner cylinder. A plurality of brush members are arranged at intervals along a spiral centering on the rotation axis of the inner cylinder. This creates a gap between the brush members, making it less likely to clog dust between the brush members, compared to the case where many bristles are densely planted in the inner cylinder. This improves the cleaning efficiency. Further, since the bristles are held by the holder, the brush member can be attached to the inner cylinder relatively easily as compared with the case where a large number of hairs are directly implanted in the inner cylinder.

  Further, if necessary, a plurality of through-holes corresponding to the plurality of brush members are formed in the inner cylinder, and a holder for the brush member is attached to a holding portion in which a large number of hairs are implanted, and the holding portion. And a fixed portion that is provided continuously and is fitted into the through hole and fixed. Thereby, since a holder can be attached to an inner cylinder only by making a fixing | fixed part fit to a through-hole, a brush member can be attached to an inner cylinder much more easily.

  Furthermore, if necessary, a bearing that rolls on the outer wall surface of the inner cylinder is provided on the lower end side of the outer cylinder. As a result, the bearing comes into contact with and supports the outer wall surface of the inner cylinder, so that the axis of the inner cylinder can be prevented from blurring. Further, when the inner cylinder rotates, the bearing rolls on the outer wall surface of the inner cylinder, so that the frictional force between the inner cylinder and the bearing is reduced, so that the inner cylinder can be smoothly rotated.

  Further, if necessary, the drive unit is configured to include a motor having a rotation axis that is fixed to the upper end of the outer cylinder via a fixing member and that is coaxial with the axis of the inner cylinder. The inner cylinder is suspended from the tip via an attachment member. Accordingly, when the motor is driven, the rotation shaft is rotated, and the attachment member is rotated by the rotation of the rotation shaft. When the mounting member is rotated, the inner cylinder is rotated around the axis, whereby the road column can be cleaned. That is, since the inner cylinder can be automatically rotated by the drive unit, the workability of the road column cleaning work can be improved as compared with the conventional case.

  Furthermore, if necessary, the moving mechanism is supported by a rod-shaped first support member that supports the motor in a suspended manner, and the first support member is supported at one end so that the first support member can move up and down, and is orthogonal to the longitudinal direction of the first support member. A rod-like second support member having a longitudinal direction in the direction to be moved, a third support member that supports the other end side of the second support member so as to advance and retract along the longitudinal direction of the second support member, A base that supports the three support members so as to be pivotable about an axis parallel to the longitudinal direction of the first support member, a vertical movement drive unit that moves the first support member up and down, and a forward and backward movement of the second support member; An advancing / retreating drive unit to be moved and a turning drive unit for turning the third support member are provided. Thereby, when moving an outer cylinder and attaching a brush member to the support | pillar for roads, first, a 2nd support member is advanced by an advancing / retreating drive part. When the second support member is advanced, the first support member is advanced, and the motor and the outer cylinder are advanced. Next, the third support member is turned by the turning drive unit. When the third support member is turned, the second support member is also turned in the same direction as the third support member, and the first support member rotates about the base. By the advance / retreat drive unit and the turning drive unit, the lower end of the outer cylinder is positioned above the road column. At this time, the outer cylinder is positioned so that the axis of the inner cylinder and the axis of the road column are coaxial. Then, the first support member is moved downward by the vertical movement drive unit. When the first support member is moved downward, the motor and the outer cylinder are moved downward. By moving the outer cylinder, the inner cylinder is also moved, and the inner cylinder can be inserted into the road column, so that the brush member can be attached to the road column. That is, since the brush member can be easily transported and attached to the road column by the moving mechanism, the workability of the road column cleaning work can be improved as compared with the conventional case.

  According to the road strut cleaning device of the present invention, when the inner cylinder is attached to the road strut by the moving mechanism, and the drive unit is driven to rotate the inner cylinder around its axis, the inner wall surface of the inner cylinder The brush member attached to the inner cylinder also rotates in the same direction as the inner cylinder, and the rotation of the brush member causes the outer circumferential surface of the road column to be rubbed. It is possible to scrape off dirt such as dirt, and to clean the road column. That is, since the outer cylinder is moved by the moving mechanism and the inner cylinder is rotated by the drive unit, the brush member can be easily transported and attached to the road column, and the rotation of the inner cylinder causes the road column to move. Since dirt such as dust can be scraped off and removed by automatically rubbing the outer peripheral surface, the workability of the road column cleaning work can be improved as compared with the conventional case. In addition, since the outer cylinder is provided surrounding the inner cylinder, the inner cylinder rotating by the outer cylinder cannot be touched, so that the operator is injured by the rotation of the inner cylinder, etc. Accidents can be prevented.

At this time, the brush member 10 is attached so as to be in contact with the outer peripheral surface of the road column P. That is, since the brush member 10 can be easily transported and adhered to the road column P by the moving mechanism 80, the workability of the road column P cleaning operation can be improved as compared with the conventional case. .

  In this apparatus S, a guide member 50 is provided on the lower end 3 side of the inner cylinder 1, and the diameter of the lower end 3 side of the inner cylinder 1 is expanded by the guide member 50, so that the brush member 10 is used as a road post P. When attaching, even if the inner cylinder 1 is located at a position slightly deviated from the road column P, the upper portion of the road column P hits the guide member 50 and is guided into the inner cylinder 1. The inner cylinder 1 can be reliably inserted into the road column P. That is, since the inner cylinder 1 can be easily inserted into the road column P, the brush member 10 can be easily attached to the road column P.

  When the brush member 10 is attached to the road column P, the drive unit 30 is driven. At this time, cleaning water is jetted from a water jet pipe (not shown) toward the road column P as necessary. When the motor 30a of the drive unit 30 is driven, the rotating shaft 35 of the motor 30a rotates, and the mounting member 40 connected to the rotating shaft 35 rotates. The rotation of the mounting member 40 causes the inner cylinder to rotate. 1 rotates around its axis 2. Since the outer wall surface 1b on the lower end 3 side of the inner cylinder 1 is supported by the bearing 70, it is possible to prevent the rotation axis 2 of the inner cylinder 1 from blurring. Further, since the bearing 70 rolls on the outer wall surface 1b of the inner cylinder 1 when the inner cylinder 1 rotates, the frictional force between the inner cylinder 1 and the bearing 70 is reduced, so that the rotation of the inner cylinder 1 is smoothly performed. Can be done.

  When the inner cylinder 1 is rotated, the brush member 10 attached to the inner wall surface 1 a of the inner cylinder 1 also rotates in the same direction as the inner cylinder 1. Since the brush member 10 is in contact with the outer peripheral surface of the road column P, when the brush member 10 is rotated, the outer peripheral surface of the road column P is rubbed by the brush member 10. Dirt such as dust adhering to the outer peripheral surface can be scraped off and removed, and the road column P can be cleaned. At this time, since there is a gap between the plurality of brush members, dust and the like are less likely to be clogged between the brush members as compared to a case where a large number of hairs are densely planted in the inner cylinder. The function of scraping off dirt is improved, and the cleaning efficiency is improved. Further, when the cleaning water is jetted, the dirt adhering to the outer peripheral surface of the road column P can be more easily and reliably removed.

  Further, since the ventilation hole 33 is provided in the upper surface 32 of the housing 31, air enters the internal space from the ventilation hole 33 during the driving of the driving unit 30, and therefore, the motor 30 a is configured. It is possible to prevent the driven unit 30 from overheating with heat.

  That is, the brush member 10 is automatically rotated only by driving the drive unit 30. By this rotation, the brush member 10 rubs and removes dirt such as dust by rubbing the outer peripheral surface of the road column P. Compared with, the workability of the cleaning work of the road column P can be improved. Further, since the outer cylinder 20 is provided so as to surround the inner cylinder 1, the inner cylinder 1 rotated by the outer cylinder 20 cannot be touched. Accidents such as injury can be prevented.

  When the cleaning of one road column P is completed, the vertical movement drive unit 85 is driven, and the outer cylinder 20 is moved upward in the Y-axis direction in FIGS. The member 10 is detached, the apparatus S is moved to the vicinity of the road column P for the next cleaning by the automobile C, and the road column P is cleaned by attaching the brush member 10 to the road column P in the same manner as described above. To do.

In the above embodiment, the drive unit 30 is configured by the motor 30a. However, the present invention is not necessarily limited to this.
Moreover, in the said embodiment, although the brush member 10 was provided with many bristles 11, it is not necessarily limited to this.
Furthermore, in the said embodiment, although the brush member 10 was arrange | positioned spaced apart along the spiral centering on the rotating shaft 2 of the inner cylinder 1, it is not necessarily limited to this, For example, a brush The member 10 may be formed to have substantially the same length as the axial length of the inner cylinder 1, and only one brush member 10 may be provided.
Furthermore, in the above-described embodiment, 16 brush members 10 are used. However, the number of brush members 10 is not necessarily limited to this, and any number of brush members 10 may be used and may be appropriately changed.

  In the above embodiment, the vertical drive unit 85, the forward / backward drive unit 86, and the turning drive unit 87 are configured as described above. However, the present invention is not necessarily limited thereto, and may be changed as appropriate. .
