Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a scaffold cleaning machine for removing deposits such as concrete and paint adhering to scaffold frames and scaffold boards used for temporary scaffolding in construction work. It is related to.

[Conventional technology] In the construction work of a building, temporary scaffolding is created by stacking scaffolding frames near the building in multiple tiers according to the height of the building, and placing scaffolding boards between each scaffolding frame. Construction work is being carried out. Concrete from pouring concrete and paint from painting the exterior walls may adhere to these scaffolding frames and scaffolding boards, so after the scaffolding is dismantled upon completion of construction, these deposits should be removed in preparation for the next construction. We are working on removing it. Conventionally, the deposits adhering to scaffolding boards and the like have been manually removed, and this removal work is a heavy burden on the workers and has the problem of poor work efficiency. Therefore, there is a strong desire to mechanize the above-mentioned removal work. For example, as shown in Utility Model Application Publication No. 62-130785, a large number of chains are attached around a rotating shaft body, and these chains apply impact to the object to be polished. There are products that peel off and remove deposits.

[Problem to be solved by the invention] However, since the scaffolding cleaner using the above-mentioned chain mainly performs peeling by impact, it does not remove concrete or paint firmly attached to the scaffolding frame, etc. It had the problem that it could not be removed cleanly.

The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to thoroughly remove concrete and paint firmly adhered to scaffolding frames, etc. This is an attempt to provide a scaffolding cleaner that can.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a transfer means for supporting an object to be polished on a pedestal and transferring it from one end to the other end, and a means for transferring the object to be polished from one end to the other end. A pair of rotating shafts are supported horizontally with bearings at the upper and lower positions while maintaining an interval that allows the object to be polished to pass through. The shaft body is attached parallel to the rotating shaft so that it rotates integrally with the rotating shaft, and each shaft body is equipped with a number of polishing rings formed from a thin plate having an inner diameter larger than the outer diameter of the shaft body. The apparatus further includes an electric motor that rotationally drives the pair of rotating shafts.

It is preferable that the shaft body equipped with a large number of the above-mentioned polishing rings is arranged in a substantially V-shape with respect to the direction in which the object to be polished is transported.

[Function] In the scaffolding grinder according to the present invention, an object to be ground, such as a scaffolding frame, is placed on a transfer means disposed on a pedestal and is moved from one end to the other at a desired feed rate. Transfer to the department. The object to be polished passes between a pair of rotating shafts arranged above and below the object. The rotary shaft is rotationally driven by an electric motor, and a shaft body equipped with a large number of polishing rings is also rotated integrally with the rotary shaft. The large number of polishing rings collide with the object to be polished from both the upper and lower directions and scrape off the deposits. This grinding ring is loosely fitted to the shaft, so every time it collides with the object to be polished, it rotates while receding backwards, applying an appropriate force to the surface of the object to be polished. The material is rubbed off while applying a shock.

In addition, by arranging the shaft body equipped with a large number of grinding rings in a substantially V-shape with respect to the transport direction of the object to be ground, the grinding rings can also be applied to the vertical and horizontal members of the scaffolding frame. It is possible to scrape effectively by contacting in an oblique direction. Additionally, if the grinding ring collides with the object to be polished from an oblique direction, a force will be applied to shift the object laterally. The force that tends to shift in the direction is canceled out, and the object to be polished can move straight with less lateral shift.

[Example] Embodiments of the present invention will be described below based on the drawings.

The scaffold cleaning machine includes a transfer means 2 for transferring the object to be polished from one end to the other end on the pedestal 1, and a cleaning section 3 for removing deposits from the object to be polished transferred by the transfer means 2. It consists of

The transfer means 2 rotatably supports a support roller 5 with a bearing between support plates 4 erected on both sides of the pedestal 1 before and after the cleaning section 3,
Sprocket 6 attached to one end of each support roller 5
At the same time, the chain 11- is wound around the sprocket 9 of the electric motor 8 for driving the support rollers and the sprocket 10 attached to one of the support rollers 5, and the support roller 5 is rotated by the drive of the electric motor 8. The objects to be polished A fed in from the input side are transferred one after another to the rotating support rollers 5 and transported to the discharge side. Further, a presser roller 12 is provided above each support roller 5 at an interval that allows the object to be polished A to pass through. When the object to be polished A passes by, the restoring force of the spring 14 presses down the bearing 13 with an appropriate force, so that it can also absorb the shock during cleaning. .

The cleaning section 3 has a support frame 16 arranged so as to straddle the pedestal 1,
Inside the support frame 16, a pair of cleaning tools 17.17' are arranged vertically and parallel to each other with an interval that allows the object to be polished A to pass therethrough, and in a substantially V-shape with respect to the direction in which the object to be polished A is transported. It is. The cleaning tool 17.17' has both ends of the rotary shaft 20 rotatably supported by bearings 19 fixed to bearing supports 18.18° disposed on both sides and near the center of the support frame 16. A disk 21 of an appropriate radius is fixed to both ends of the rotating shaft 20 and, if necessary, to the center, and a plurality of shaft bodies 22 are fixed between the disks 21 in parallel to the rotating shaft 20. . and shaft body 22
A large number of donut-shaped polishing rings 23 formed from thin plates are attached to the holder.

This polishing ring 23 has an inner diameter larger than the outer diameter of the shaft body 22 and is attached to the shaft body 22 in a loosely fitted state.
When not rotating, it is suspended from the shaft body 22. Further, as many cleaning rings 23 as possible are attached to the shaft body 22, so that they can freely rotate around the shaft body 22 without being compressed by adjacent polishing rings 23. 24 is an electric motor that rotationally drives the rotating shaft 20, and is mounted and fixed on a motor stand 25 on the support frame 16;
A chain 28 is wound around a sprocket 26 attached to the drive shaft of the electric motor 24 and a sprocket 27 attached to the rotating shaft 20, and the electric motor 24 drives the rotating shaft 20 to rotate the cleaning tool 17.17 degrees. are doing.

Therefore, when removing deposits from an object to be polished using a scaffolding cleaner, first, the electric motor 8 of the transfer means 2 is driven to rotate each support roller 5, and the electric motor 24 of the cleaning section 3 is driven to rotate each support roller 5.
to rotate the cleaning tool 17.17°. Then, the object to be polished A is placed on the support roller 5 at one end of the scaffold cleaner and fed at a desired feed speed. The object to be polished A passes between the cleaning tools 17.17° arranged above and below while being pressed by the presser roller 12 with an appropriate force. Cleaning tools 17.1
7° is rotating at a high speed, and the cleaning tool 17. The cleaning ring 23 at 17° collides with the object to be polished A passing through, impacting the object from both the top and bottom, and removing deposits. It scrubs away. Since this polishing ring 23 is loosely fitted to the shaft body 22, it does not move backward every time it collides with the object A, so it contacts the surface of the object A with an appropriate force. It is used to scrape off deposits, and it can also rub the surface of the object to be polished, following the uneven shape of the object. The embodiment drawing shows a case where two cleaning units 3 are arranged, but when multiple units are arranged in this way, the rear-stage cleaning tool 17.17' rotates in the opposite direction to the front-stage cleaning tool 17.17°. By doing this, the contact surface of the cleaning tool 17.17° on the object to be polished will be different, and even a vibrator-shaped tool can remove deposits from every corner.

In addition, by arranging the shaft body 22 equipped with a large number of grinding rings 23 in a substantially V-shape with respect to the transport direction of the object to be ground A, the vertical and horizontal members of the scaffolding frame can also be ground. ring 23
can contact in an oblique direction and scrape effectively. Furthermore, if the polishing ring 23 collides with the object to be polished A from an oblique direction, a force that shifts the object to be polished in the horizontal direction will be applied. The force that tends to shift in the lateral direction is canceled out, and the object to be polished A can be moved straight with less lateral shift.

Although the cleaning tools 17 and 17' are arranged in a substantially V-shape with respect to the direction in which the object to be polished A is transported, they may be arranged perpendicularly to the direction in which the object to be polished A is transported. Further, one cleaning tool may be arranged at an angle instead of being divided into a substantially V-shape, and in this case, it is preferable to provide a guide member to prevent the tool to be polished from shifting in the lateral direction. Further, in the embodiment, two sets of polishing units 3 are arranged, but an appropriate number may be arranged as required.

Furthermore, although the outer shape of the polishing ring 23 is circular in the above-described embodiment, it is not limited to this shape in any way, and may be, for example, elliptical or gourd-shaped.

[Effects of the Invention] As described above, in the scaffolding cleaning machine according to the present invention, a large number of cleaning rings 23 are loosely fitted to the rotating shaft 22, and the cleaning rings 23 are attached to the rotating shaft 22 in a loosely fitted manner. Since the polishing ring 23 is caused to collide with the object to be polished A, each time it collides with the object A, the polishing ring 23 moves backward and contacts the surface of the object to be polished with an appropriate force to remove sticky paint or strong It can also effectively scrape off concrete, etc. that has adhered to the surface.

In addition, by arranging the shaft body 22 equipped with a large number of grinding rings 23 in a substantially V-shape with respect to the transport direction of the object to be ground A, the vertical and horizontal members of the scaffolding frame can also be ground. ring 23
can contact in an oblique direction and scrape effectively. Furthermore, by arranging the polishing ring 23 in a substantially V-shape, the force that tends to cause it to shift laterally due to impact is offset.
Another advantage is that the object to be polished is less likely to shift in the lateral direction and can be moved straight, allowing for smooth transfer.
