Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cleaning device for removing concrete adhering to pipe supports and other pipes used in construction work.

[Conventional technology]

Concrete adheres to pipes such as pipe supports used in construction work, so concrete must be removed before reuse.

By the way, the removal of concrete adhering to pipes was done manually.

[Problem that the invention attempts to solve]

Since the removal work was carried out manually, there were problems such as extremely poor work efficiency, high work costs, and heavy labor.

[Means for Solving the Problems] In order to solve the above problems, this invention includes a pipe feeding device, the tip edge of each pipe is pressed against the outer periphery of the pipe run by this feeding device, and the rotating It is composed of a large number of resilient scraping cleaning plates.

[Effect]

The pipe is fed to a feeding device to run the pipe, and concrete adhering to the outer periphery of the pipe is scraped off by a rotating cleaning plate.

〔Example〕

In the figure, 1 is a feeding device for pipe A.

The above-mentioned feeding device 1 has an annular groove 2 for holding the pipe A on its outer periphery, and a pair of upper and lower pinch rolls 3 with a drive function for running the pipe A are arranged at a predetermined interval in the front and rear. , the number of pinch rolls may be increased depending on the length of the pipe.

Further, the annular groove 2 is formed in a semicircular shape in the case of a round pipe, and in a V-shape in the case of a square pipe.

Furthermore, the drive function of the pinch roll 3 is as follows:
Gears 5 fixed to each shaft 4 of the pinch roll 3 are engaged with each other, and a chain 9 is stretched between the sprocket 7 of the motor 6 and the sprocket 8 fixed to one of the shafts 4. ,
It may also be driven by other configurations.

As shown in the figure, both ends of the lower shaft 4 of the pinch roll 3 are supported by fixed bearings 10, and through holes 11 are provided at both ends of the upper shaft 4.
By passing the guide shaft 12 perpendicular to the pipe and pushing down both ends of the shaft 4 having the through hole 11 by the spring 13, the tip of the pin and the caulking head of the pin protrude from the circumferential surface of the pipe. Even if the pipe A is closed, the upper pinch roll 3 can be released upward and the pipe A can be run.

14 is a rotating cleaning plate that scrapes off concrete adhering to the outer periphery of the pipe A while the pipe A is running.

As shown in FIGS. 1 to 7, the cleaning plate 14 has a pair of front and rear discs 16, 16 facing each other, each having a passage through hole 15 for the pipe A in the center, and both discs 16, 16 facing each other. A line connecting both ends to the required spacing position of the opposing surfaces of pipe A crosses the axis of pipe A at a predetermined angle, and the opposing spacing of each end located on the inlet side of pipe A is the opposing end of each end located on the outlet side. Both ends of the support plate 17 are fixed so that the spacing is larger than the gap, and a scraping cleaning plate 14 and a presser plate 18 made of elasticity such as rubber are sequentially stacked on one side of the support plate 17, and the cleaning plate 17 is separated from the support plate 17. 14. Insert the fastener 19 consisting of a bolt and nut into the holding plate 18 (by providing a long hole in the cleaning plate 14, the protruding position of the tip of the cleaning plate 14 can be freely adjusted). The collective cleaning plate 1
The pipe A can easily enter the pipe A, and the pressure of the cleaning plate 14 against the pipe A becomes stronger from the inlet side toward the outlet side, making it possible to effectively scrape off adhering concrete.

Further, as shown in FIGS. 8 and 9, rotating shafts 20, 20 are provided on the upper and lower sides of the running pipe A, the axes of which intersect at right angles to the axis of the pipe A, and are opposed to both rotating shafts 20, respectively. disk 21,
Support plates 22 are arranged radially at required intervals on opposing surfaces of the disks 21, 21, with one side of the disks 21 fixed.
At the same time, the cleaning plate 14 and the holding plate 23 are sequentially stacked on one side of the supporting plate 22, and a fastener 24 consisting of a bolt and a nut is inserted from the supporting plate 22 to the cleaning plate 14 and the holding plate 23. (By providing a long hole in the cleaning plate 14, the protruding position of the tip of the cleaning plate 14 can be freely adjusted.) Press the edge of No. 25 (in the case shown, it is cut in a V shape to clean square pipe A, but in the case of a round pipe, it is sufficient to cut it in a semicircle shape) against the outer periphery of pipe A to scrape off the adhering concrete. You can do it like this.

The cleaning plate 14 is composed of a rubber plate and a bundle of wires 26 embedded in the rubber plate in parallel so as to be parallel to the axis of the pipe, thereby giving the rubber plate some stiffness.

In addition, if a reinforcing plate 27 is pasted on one side of the rubber plate, it is possible to further increase the stiffness.

Further, the annular grooves 2 of the pinch rolls 3, 3 are formed in a semicircular shape in the case of a round pipe, and in a V-shape in the case of a square pipe.

In the figure, 28 is a motor, and the pulley 29 of this motor 28 and the pulley 3 provided on the outside of the disc 16
The cleaning plate 14 is rotated by passing a belt 31 between the cleaning plate 14 and the cleaning plate 14. 32 is both rotating shaft 2
A belt (not shown) is passed between the pulley 33 attached to one rotating shaft 20 and the pulley 29 of the motor 28 to drive both rotating shafts 20, 20. It's getting old.

The cleaning device according to this invention has the above configuration, and its operation will be explained next.

While the pipe A is running by the feeding device 1, an impact is applied to the pipe A by the tip edge of each rotating cleaning plate 14 while the pipe A is running, and the concrete adhering to the surface of the pipe A is forced to be scraped. peel off.

〔effect〕

As described above, according to the pipe cleaning device of this invention, while the pipe is being moved by the feeding device, an impact is applied to the moving pipe by the tip edge of each cleaning plate, and it is rubbed and adhered to the surface of the pipe. By peeling off the concrete that is stuck to the concrete, it is possible to automatically remove the deposits. Automation of the work makes it possible to improve efficiency and save labor, and it is possible to significantly reduce the cost of cleaning work. The rubber plate of the cleaning plate is supported by a bundle of wires buried in parallel, so the pressing force of the tip edge of the rubber plate against the pipe surface is strong, rubbing the pipe strongly and making it firmly adhere to the concrete. can be reliably removed.
