SU1222565A1 - Centrifuge for shaping bodies of revolution from concrete mixes - Google Patents

Description

one

The invention relates to the technological equipment of the building industry and can be used for the production of concrete and reinforced concrete pipes and rings for various purposes.

 The purpose of the invention is to simplify the structures.

Fig. 1 shows an installation for forming bodies of revolution, vertical section; figure 2 is a view of And figure 1; on fig.Z - section BB in figure 1; figure 4 - section bb In figure 1.

The installation comprises a frame 1, a form 2 with raceways, a form bed made of traverse 3 with supporting rollers 4, suspensions 5 attached to the frame and mounted on axles 6 inclined tons g.

Suspension 5 is made in the form of spring-loaded inclined tg, attached to the frame by means of traverse 7 and nuts 8, between which springs 9 are mounted, and to traverse 3 by means of a two-joint element 1 rigidly connected to axis 11 of traverse 3 ..

The centrifuge on top is closed by a protective shield 12.

The device for forming bodies of rotation works in the following way. The upper protective shield 12 is removed and the roller tracks 4 are installed on the roller 2 prepared for the molding on the support rollers 4 traverse 3 of the mold bed. Then the shield 12 is closed and the inlet is applied to the end of the form. a coordinate coupling is connected kinematically connected with the shape drive, and the shape is rotated according to a predetermined mode. Supplied to the form, for example, the concrete mix is distributed on its inner surface, and then compacted, forming the product 13.

In the process of rotating the shape of its track, the rollers run along the support rollers of the mold bed. And since the suspensions 5 are rigidly attached to the front axle 6, which has the ability to rotate around the axis 11 relative to the other axes of the traverse with supporting rollers 4, the latter strictly follows the suspension and therefore is absent

friction traverse along the tracks in the direction of the axis of the form. Thanks to the springs 9 located between the cross-pieces 7 mounted on

5 frame 1, and nuts 8, screwed on the ends of the suspensions 5, are localized, with usually beatings, resulting from some imperfection of the raceways of the forms and

0 forms.

After the product is molded, the rotation of the mold is stopped, the coordinate sleeve 14 is disconnected from the mold, the shield 12 is removed and

5 with the help of a crane (crane beam) capture and transport the form, first outside the installation, and then to the post-heat treatment station. On the installation serves the next form and

0 process is repeated.

The transfer of rotation to the form from the actuator by means of a coordinate clutch prevents the drive from additional load arising from some, albeit insignificant, misaligned rotation of the form relative to the initial position of its axis. The transfer of rotation to the form can also be carried out in a known 30 manner using a flexible leash or using belts which kinematically connect at least one form roller track with an actuator.

5 In the same way as in the aforementioned known apparatus, the ends, of the form can be provided with protrusions interacting with stops mounted at the ends of the form to create shock impulses on the form in the direction of its axis.

For the manufacture of pipes of smaller diameters, the mold bed is made of cross-arms with supporting rollers, each

45 of which has only two rollers, with the axis of the rollers mounted with the possibility of rotation one relative to another. For pipes of larger diameters, each of the cross-arms can be supplied on four rollers or the form bed can be mounted so that each form raceway rests on two or more traverses with support rollers connected to one another.
