Description

The invention relates to the technological equipment of entertainment facilities.

The purpose of the invention is to expand the functionality by increasing the number of operating modes.

The drawing shows a transforming platform, a slit.

The transforming platform contains two guiding rings 1 and a screw 2 fixed on the enclosing building structures 3. Glasses 5 are attached to the frame of the platform 4, inside of which they are fixed with the possibility of extension and rotation of the stand 6 with the support rollers 7 which are fixed on their limbs, interacting with guides 1 or 2. The supports 6 in the cups 5 are fixed with fixing devices made in the form of pins 8, passing through the holes 9 in the racks 6 and the holes 10 and 11 in the glasses 5. In this case

the lower row of holes 10 in the cups 5 forms an annular line, and the upper row of holes 11 is a helix similar to the screw guide 2. The radius of the ring guide is smaller than the radius of the screw guide by a double fold of the legs. The rotation of the platform is carried out by any drive, most often cable-driven (not shown).

The operation of the device is as follows.

In the first mode of rotation of the platform, performed without lifting, the rollers 7 roll in along the annular guide 1 in the plane of this guide. At that, the struts 6 are extended before the interaction of the supporting rollers 7 with the annular guide 1 and fixed by pin 8 through the holes 9 and 10 of the cup 5 and racks 6.

In the mode of rotation of the platform with the rise (the second mode of operation of the device), the rollers - 7 interact with the screw

guide; 2, and the movement of all points of the platform is carried out along a helix, i.e. it rotates simultaneously and extends to the height of the pitch of the screw guide 2. In this case, the legs 6 are extended from the bowl 5 to different heights for each roller 7 to ensure that all the rollers interact with the screw guide 2 and are fixed by pin 8 through holes 9 and 11. In this case, the supports 6 are deployed in the glass 5 by 180 °, and the kagki 7 interact with the guide 2. When using rotation with a lift to improve visibility when organizing a remote stage, the platform rotates by 180 °, and the length of the screw guide has a half turn. Rotation of the platform by 180 ° provides the location of the external stage between the platform’s orchestra and the rus of the auditorium, and the platform’s rise ensures a normal viewing angle for the Rus. In this case, the angle of visibility for the stalls of the remote scene remains the same. The required lifting of the platform is ensured by the pitch of the screw guide 2, and the length of the screw guide is one and a half turns due to the fact that 0.5 turns are needed to turn the platform through 180 ° and one turn to guarantee the interaction of the rollers 7 with the screw guide 2. It should also be noted that since the proposed transforming platform turns on a fixed screw guide and rotation is not carried out through drive rollers and idle, the question of coupling weight is not essential in this design. The movements and number of rollers can be adjusted depending on the load on the platform. Apply

The development of a transformable platform for spectacular structures allows for two modes of operation of the device, namely, it allows the platform to turn both without lifting and with lifting. In this case, the lifting of the platform is carried out in a simpler way than in the prototype, since the number of rollers is adjusted depending on the load on the platform and, thus, a complex system of hydraulic locks is not required to keep the platform in working position. In addition, the platform design allows, due to the original mounting of the rollers, to quickly change the operating modes of the device.
