Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a steel frame for construction and a scaffolding plate for construction used for scaffolding for construction.

[0002]

2. Description of the Related Art In scaffolding for construction, a plurality of pipes for construction scaffolding, which are welded in a rectangular shape, are combined, and a steel cloth frame or scaffolding board is hung on the pipes to form a scaffolding. The construction steel frame and scaffolding board will be used for the next time after foreign substances such as concrete adhering to the surface are removed after the work is completed. Generally, a large lump of concrete adhering to each part is knocked down with a hammer, or a worker manually removes concrete adhering to each part. Therefore, it is necessary to work long hours in a bad environment where dust and dirt are floating.

In recent years, for the purpose of improving this adverse environment, a cleaning device as shown in FIG. 3 has been devised and used for a steel frame for construction. This cleaning device cleans the surface of the cloth frame Z by mounting a steel cloth frame Z on the carrying frame 16 and moving it directly under the wire brush 6 that rotates together with the carrying frame. It contributes to environmental improvement. Normally, the carrying frame 16 moves on the rails 15, and the drive thereof transmits the rotation of the motor 13 to the frame via the conveyor chain 14.

[0004]

However, in the apparatus, in order to clean cloth frames of different types such as length and thickness due to the existence of the carrying frame with the same cleaning device, the cloth frame of the carrying frame is to be cleaned. It was necessary to change the setup of the mounting part, and it was impossible to easily mix and clean any kind of cloth frames.

Further, it has been impossible to use the scaffold plate because it is difficult to fix its position on the carrier frame. Further, in this structure, the next cloth frame cannot be loaded until the cleaning of one cloth frame is completed and the cloth frame is carried out to the initial mounting position, which is a problem in terms of productivity.

[0006]

Therefore, in order to solve these problems, the present invention solves these problems by a rotary wire brush, a rotary chain brush, and at least two pairs of rotary drive rollers for carrying a cloth frame and a scaffold plate. Of the pair of rotary drive rollers, the roller located on the brush side is installed at a position where the center of rotation is fixed relative to the brush, and the roller located on the side opposite to the brush is the center of rotation thereof. It is a basic feature of the cleaning apparatus that the cleaning device is installed so as to be movable relative to the facing roller, and is pressed against the facing roller by the biasing means.

[0007]

According to the cleaning apparatus for the steel cloth frame and the steel scaffolding plate having the above construction, the surface to be cleaned of the object to be cleaned is always in contact with the rotary drive roller on the brush side whose rotation center is fixed, and the rotary wire It is kept at a constant distance from the brush and the rotary chain brush, so that any thickness of cloth and scaffolding can be cleaned under certain conditions.

Further, since the object to be cleaned is conveyed while being sandwiched between the rotating rollers facing each other, there is no problem even if the length and width are different, and even if it has hooks at both ends like a cloth frame. Even a scaffold plate having a simple plate shape can be cleaned without changing the setup.

Furthermore, according to the cleaning device for the structured fabric frame and the structured scaffolding plate of this structure, since the carrying-in part and the carrying-out part of the article to be cleaned are located in opposite directions of the both ends of the apparatus, the article to be cleaned is continuously placed. It can be put into a device and productivity is improved.

Furthermore, according to the cleaning device of this structure,
Of the foreign matter adhering to the surface of the object to be cleaned, those with a relatively large and strong adhesive force are knocked off by the chain brush, and those with a comparatively small size that are in the joint groove or surface dent are scratched with a wire brush. Since it is dropped, the deposits on the surface can be effectively removed even by cleaning for a short time, so that the productivity is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view showing the configuration of a cleaning device according to an embodiment of the present invention. FIG. 2 also shows a perspective view. In the figure, Z represents a steel cloth frame to be cleaned.

The cleaning device is roughly classified into a transport drive unit for transporting an object to be cleaned, a rotary brush unit for cleaning the object to be cleaned,
It is divided into structural members such as a frame and a dustproof cover.

The transport drive unit includes an upper drive roller 1 having a fixed rotation center, a bearing (not shown) for supporting the roller, a lower drive roller 2 having a rotation center vertically movable, and the roller. Bearings to support (not shown)
A spring 3 for pressing the lower drive roller to the upper drive roller side, a motor 4 for driving those rollers, and a chain 5 for transmitting the driving force of the motor to each roller shaft.

The rotating brush portion includes a wire brush 6, a chain brush 7, a motor 8 for driving them,
It is composed of a chain 9 for transmitting the driving force of the motor to each brush.

The structural member is composed of a frame (not shown) for supporting the entire apparatus, a dustproof cover 10, a guide 11 for introducing an object to be cleaned, and a guide 12 for carrying out the object to be cleaned.

Next, the procedure for cleaning the steel cloth frame and the steel scaffolding board using this apparatus will be described. When the cloth frame or scaffolding plate placed on the guide for loading the object to be cleaned is manually pushed into the device as it is, the cloth frame or scaffolding plate enters between the upper and lower drive rollers so as to spread between the rollers,
It is carried in to the back of the device one by one.

The object to be cleaned carried into the apparatus by the drive roller moves to the inside of the apparatus with the surface to be cleaned being pressed against the upper drive roller, and first, the center of rotation of the chain brush is immediately below the chain brush. And move while maintaining a certain distance. The chain brush has a cylindrical drum with one end fixed to the surface of the drum and the other end formed into a brush in a free state.The centrifugal force generated by the rotation of the drum causes the chain to reach the surface to be cleaned of the object to be cleaned. It works so that it can be struck. As a result, the foreign matter attached to the surface to be cleaned is knocked off.

Next, the object to be cleaned is moved right below the wire brush by the drive roller, and by the same movement as the chain brush, the foreign matter adhering to the surface to be cleaned is removed by the wire brush. After that, the object to be cleaned is further transported to the inner part of the device by the drive roller, reaches the guide part for carrying out, and is discharged to the outside of the device.

By the procedure described above, the object to be cleaned introduced from the carry-in guide is carried out from the carry-out guide after the surface to be cleaned has been cleaned. Then it is carried out.

[0020]

According to the present invention, it is possible to continuously clean cloth frames and scaffolding plates having different lengths, widths, and thicknesses without changing the stage, and to be cleaned objects having different sizes. The same cleaning effect can be obtained.

Further, due to the two-stage effect of scraping off the foreign matter with the chain brush and scraping off the foreign matter with the wire brush, it is possible to increase the conveying speed of the article to be cleaned in the apparatus as compared with the conventional apparatus. In addition, since it is possible to continuously load the object to be cleaned, the productivity of the cleaning work can be significantly improved.

According to the cleaning device of the present invention described in detail above, the steel frame and the steel frame for construction can be efficiently used in a safe and comfortable working environment easily and without requiring the labor of the operator. You can clean scaffolding boards.
