Description

one

The invention relates to the construction, in particular, to devices for cleaning the surface of the molds from concrete and grease residues, and can be used in prefabricated reinforced concrete plants.

A device for cleaning surfaces is known, including rotating discs and a spacing mechanism for pressing them against the walls f .10

The specified device requires additional adjustment and control in the work when setting it in the optimal mode.

It is also known a device for cleaning molds comprising a working body mounted on a frame in the form of a shaft with rigidly fixed brushes with a drive mechanism, and a mechanism for moving the working body 2.

However, such a device provides for cleaning only linear parts,.

The purpose of the invention is to provide the possibility of cleaning curvilinear shapes. 25

The goal is achieved by the fact that in the device for cleaning the forms containing a working body mounted on the third body in the form of a shaft with rigidly fixed brushes with a scraper mechanism

water and the mechanism for moving the working body; the frame is equipped with a slider on which the mechanism for driving the shaft of the working body is housed and curved rails adjustable in height, the working body connected to the slider by two-hinge rods, and the shaft has freely mounted rollers curved guides, while the device has limit switches installed at the ends of the frame.

FIG. 1 shows the proposed device, a general view of FIG. 2 - section A-A in FIG. one.

The device for cleaning the forms comprises a frame 1 on which copying guides 2 are installed with the possibility of height adjustment by means of screw mechanisms 3. The configuration of the copy guides 2 repeats the configuration of forms 4 with open sides 5. The form can either be moved (with a conveyor method production) through the drive 6 movement, or installed stationary (with bench production method), while the frame 1 is mounted on the wheels and moves along the rails. The working body 7 consists of

brushes 8, made in the form of a cable disbanded at the working end, which when in contact with the working surface of the form 4 does not leave any scratches, shaft 9, {and which freely installed rollers 10 are in contact with the coping rails 2. Sprockets are also rigidly fixed 11 are connected by chain transmitters 12 to the drive shaft drive mechanism of the working member 13 and the rods 14 are hinged, connecting the working member 7 with a slider 15 which can move along. fixed guides 16 by means of the drive mechanism 17. At the extreme positions of the cart at the ends of the frame, limit switches 18 and 19 of the mechanisms for driving the working body and moving the rotation drives 13 are installed.

The device works as follows.

Before starting the operation, the slider 15 and the working body 7 kinematically associated with it are in the extreme right position. After installation of the mold 4, when the conveyor b drive is pushed to the cleaning post, the drive unit of the working element 13 and the displacement 17 simultaneously turn on. At that, the slider 15 moves along the stationary horizontally installed directions to frame 16 of frame 1, and double-sided rods 14, which are installed in the initial position at an angle to the horizon, provide the movement of the working body 7 on the copy guide 2 without jamming. The screw mechanisms 3 allow adjusting the height of the guides and, therefore, the working body 7 when processing the forms 4 of different height and when the brushes are worn. The rollers 10 installed with the possibility of free rotation around the shaft 9 allow the working body to smoothly move along a curve as close as possible to configuration of the pallet and board equipment. In the leftmost position from the limit switch 19, the mechanisms of the drive 13 and the movement 17 are turned off and the drive of the conveyor 6 is turned on, moving the cleaned form 4 to the next post.

Spring tensioned sprockets are used to provide constant tension on the chains 12.

When cleaning the following form, the mechanisms 13 and 17 are reversed and the cleaning cycle is repeated until limit switch 18 is activated.

The use of the proposed device will ensure high-quality cleaning of working surfaces.

Forms with a curved surface for conveyor or bench production of reinforced concrete structures and due to the interaction of brushes with working surfaces of the form along its entire length (or width), increase

the quality of the products, since the mold is completely cleared of concrete and lubricant residues.
