Description

[Detailed Description of the Invention] The present invention provides a method for removing mud adhering to steel sheet piles after use.
This invention relates to a continuous mud, rust, etc. removal device for steel sheet piles that can continuously and efficiently remove rust, etc., and its configuration will be described in detail with reference to the accompanying drawings as follows.

The entire elongated machine frame 1 is covered with a cover 2, one end of the long side of the machine frame 1 is used as a feeding part 4 for steel sheet piles 3, and the other end on the opposite side is used as a feeding part 5.

Between the feeding section 4 and the feeding section 5, a pair of upper and lower feeding rollers (a press roller 7, a driving roller 8) are provided at approximately equal intervals to pressure the front and back surfaces of the steel sheet pile 3 and feed the steel sheet pile 3. A pair of upper and lower rotating brushes (roller brush 9, disk-shaped brush 10) that remove mud, rust 6, etc. while rotating and press against the front surface 3a and back surface 3a of the steel sheet pile 3 in the feeding direction, and grooves 3c on both edges of the steel sheet pile 3. A scraping tool (raking rod 11) that removes mud, rust 6, etc. while sliding and fitting into the steel sheet pile 3; 14) A pair of upper and lower scraping rollers 12, 1 scrape off mud, rust, etc. 6 while rotating and pressing against the front surface 3a and back surface 3b of the steel sheet pile 3.
3, and a device a for removing mud, rust, etc. is provided inside the cover 2, and the dirt, rust, etc. removed during work is removed from the upper part of the cover 2.
A dirt, dust, etc. suction removal device b is provided to remove dust by suction, and a mud, rust, etc. recovery device c is provided below the machine frame 1 to collect removed mud, rust, etc.

The dust, dust, etc. suction removal device b shown in the drawing is installed on the machine frame 1.
A suction tube 15 is provided approximately at the upper center of the suction tube 1.
The figure shows a case in which a suction fan 16 is indirectly connected to the dust, dirt, etc. suction removal device b.
may be located not only at one location but also at two or three locations depending on the length of the machine frame 1.

The mud, rust, etc. collecting device c in the drawing is located at the bottom 1 of the machine frame 1.
A screw conveyor 17 is provided in the length direction on the top a, and a mud, rust, etc. removal port 18 is provided at the bottom 1a on the sending part 5 side.
The figure shows the case where the

In the figure, 19 is the rotating shaft of the presser roller 7, 20 is a bearing arm that moves up and down by the cylinder movement, and 21
2 is the rotating shaft of the drive roller 8; 22 is its bearing; 2
3 is a mounting rod that has been removed against the spring 32 of the scraping rod 11, 24 is a pivot shaft, 25 is mud,
An air pipe for blowing away rust 6, etc., 26 is the rotating shaft of the roller brush 9, 27 is its bearing part, 28 is the rotating shaft of the cylindrical brush 14, 29 is its bearing part, 3
0 and 31 are the rotating shafts of the scraping rollers 12 and 13, and 33
is a guide roller.

After using steel sheet piles, mud, rust, etc. adhere to them, so the mud, rust, etc. have to be removed before the next use, making it difficult to use. There was a drawback that if there were any such things attached, the product would not be commercially available.

Traditionally, there was no special machine available to remove mud, rust, etc. from steel sheet piles, so the work was difficult because most of the work was done by hand.

For this reason, lease prices were currently high.

The present invention solves this drawback, and since it is constructed as described above, when the steel sheet pile 3 is fed from one side, the steel sheet pile 3 is divided into the front surface 3a and the back surface 3b of the steel sheet pile 3.
a pair of upper and lower rotating brushes that remove mud, rust 6, etc. while rotating and pressing the steel sheet piles 3; a scraping tool that removes mud, rust 6, etc. while sliding by fitting into the grooves 3c on both edges of the steel sheet pile 3;
While rotating and pressing against both outer surfaces 3d of the steel sheet pile 3,
Rotating brush for removing rust 6 etc., surface 3 of steel sheet pile 3
a, the front and back surfaces 3a, 3b, and both sides are removed by a mud, rust, etc. removing device a, which comprises a pair of upper and lower scraping rollers 12, 13 that scrape off mud, rust 6, etc. while rotating and pressing against the back surface 3b; Mud, rust 6, etc. on the outer surface 3d and both edge grooves 3c are surely polished off and removed.

The cleaned steel sheet pile 3 is sent out from the other side.

Therefore, the worker only needs to feed the steel sheet piles 3 into the feeding section 4, and then take out the clean steel sheet piles 3 sent out from the feeding section 5. In this way, the steel sheet piles 3 are continuously cleaned of dirt, mud, etc. Since rust 6 and the like can be completely removed, work efficiency is greatly improved, and the lease price of steel sheet piles 3 is reduced accordingly.

Naturally, dirt, dust, etc. will be generated when removing mud, rust, etc., but these light dirt, dust, etc. can be removed using the dirt, dust, etc. Since the removal device b constantly sucks and removes the dirt and discharges it to the outside, the dirt, dust, etc. will not be scattered around, and there is no need to worry about pollution or noise problems.
Mud, rust 6, etc. that are not suctioned away by dust, dirt, etc. suction removal device b are constantly collected by mud, rust, etc. collection device c, so this mud, rust 6, etc. are collected after work.
It is easy to clean up afterward, as you can stuff the items in a bag or the like and throw them away.

Furthermore, by installing the dirt, dust, etc. suction removal device (b) above the dirt, dust, etc. removal device (a), the dirt, dust, etc., mud, rust, etc. generated by the dirt, dust, etc. suction removal device (b) is constantly removed during work. Since the steel sheet piles 3 are removed by suction, there is no dirt, dust, mud, rust, etc. attached to the steel sheet piles 3 that are sent out from the delivery section 5, and the steel sheet piles 3 are cleanly finished and can be used as products as they are. It has excellent features such as:
