This invention relates to equipment for the production of concrete and reinforced concrete products on cassette conveyor lines.

The purpose of the invention is to simplify the design, improve the quality of cleaning and provide ease of operation.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 - section GGD in FIG. four; in fig. 6 is a view of D in FIG. four.

The device for cleaning boards in vertical molding installations of reinforced concrete products consists of a frame 1 mounted on wheels 2 and provided with supports 3 for its rotation. On frame 1, using fingers 4, are fixed four levers 5, on which split cups 6 are rigidly attached in a horizontal plane, each pair of levers 5 are hingedly connected to each other by connecting links 7, and the joint 8, connecting links 7, is connected by a cable 9, thrown over the block 10, with a counterweight 11.

In the split cups 6, the beam 13 is fastened with the help of the joint supports 12, provided with cleaning elements in the form of scrapers 14.

 The fixing device of the scraper consists of a stop 15 with slits on both sides, which include the bases of the scraper 14, tongue 16, passing through the hole in the scraper 14, elastic material 17 that presses the scraper to the splinter 18. To the scraper 14 with screws 19 replaceable blade 20 is attached.

The frame 1 is pivotally attached to the swivel bar 21, connected by cables 22, slid over blocks 23, with counterweights 11, and an additional scraper 24, mounted in a horizontal plane and connected by cables 25, thrown over blocks 26, with a counterweight 11.

In order to ensure stability, the device is equipped with a counterweight 27.

In order to automatically turn the device on and off, a controlled stop 28 is placed on the system to be cleaned.

The device works as follows.

zom.

To clean the installation, the device is fed from the sediment area with a transfer carriage to the opened vertical molding installation, from which the mold has been previously removed. The pusher of the transfer trolley pushes the device for stops 3 into the molding unit, while turning the rod 21, in contact with the stop 28, rotates, the cables 22 loosen, the counterweights 11 pull the cables 9, acting through the hinge 8 on the connecting links 7,

which press on the levers 5, turning them towards the surfaces to be cleaned. The levers 5 through the glasses 6 and the ball bearings 12 act on the beam 13, pressing the blade 20 of the scrapers 14 to the surface to be cleaned. As the device advances, scraping occurs on the 14 forming surfaces of the vertical forming unit. Blades 20 scrapers 14 remove attached concrete, which falls into the gap between the rails, from where scraper 24 is pushed out of the installation. During the return stroke, when the device is moved from the installation to the transfer carriage, scrapers 14 mounted on beams on the opposite side are included in the operation.

When the device leaves the installation, the controlled stop 28 is lowered. The rotary rod 21, in contact with the stop 28, rotates, the cables 22 are tensioned, the counterweights 11 are raised, turning them off from work at the same time the cables 25 are pulled up, the stretcher 24. located on the transfer cart. Next, it is moved to the next molding compartment or to the place of sludge.

To replace the scraper 14, simply remove the pin 18 from the pin 16, rotate the scraper relative to the slot in the stop 15, withdraw the pin 16 from the hole in the scraper, install the new scraper in reverse order.

Claims (2)
