Description

one

The invention is intended primarily for cutting a raw array of cellular concrete in the manufacture of building products, such as panels and blocks.

Devices are known for cutting an array of cellular concrete, comprising a pallet with transverse and longitudinal beams, a frame with tensioned cutting strings, and an irrigator for moving the frame. In particular, such a device is known comprising a device for raising and lowering beams.

However, the device for raising and lowering beams of the known device has a complex structure, which limits its use and reduces reliability in operation.

The purpose of the invention is to simplify the design of the device and increase the reliability of its operation.

For this, the device is equipped with double shoulders with horizontal axes and rollers at the ends hinged on the crossbeam, and curvilinear guides mounted on the frame and in contact with one of the double arm levers, while the rollers of the other shoulder are supported on the longitudinal beam of the pallet.

FIG. 1 shows the proposed device, side view; in fig. 2 is a fragment of a general view of the device on a larger scale, illustrating the construction of the pallet and the means for lowering and raising the beams (to more clearly represent their interaction shown in close proximity to each other); in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 2; in fig. 5-device (main part) during operation, longitudinal section.

Poddop formed from a variety of transverse beams 1 by means of hinges 2, mounted on the longitudinal beams 3. To the transverse beams 1 at both ends are attached by means of double-arm hinged arms 4

horizontal axles 5 with the rollers 6 mounted on them. One shoulder 7 of the double-arm 4 in the initial position of the transverse beams 1 (see Fig. 2-4) rests on the longitudinal beam 3 through the roller 8, mounted on

axis 9. The rotation of the two shoulders 4 relative to the transverse beams 1 is bounded on both sides by the stops 10. In the shelf of the longitudinal beam 3 at the place of the bearing of the two shoulders lever 4 a notch 11 is made.

The device is equipped with a frame 12 installed in such a way that its lower cross-member (in Fig. 5 is shown in section) is below the supporting surface of the transverse beams 1 in their initial position and above

beams 1 in their lowered position. Frame 12

mounted horizontally on wheels 13 along rails 14 by means of an actuator not shown in the drawings. On the frame 12 natuts cutting strings 15.

Curved guides 16 of U-shaped cross-section 16 are attached to frame 12 on both sides with the possibility of contact with rollers 6.

An array 17 to be cut is installed on the transverse beams 1 (the frame 12 is in the extreme position and does not install the array 17).

Then the frame 12 is turned on and together with the curved guides 16 it moves to the right (Figs. 1 and 5). At the same time, the rollers 6 fall alternately into the groove of the U-shaped cross section of the curved guides 16, turning the two shoulders levers 4 in the direction indicated by the arrow in FIG. 2. The roller 8 moves along the flange of the longitudinal beam 3 and falls into the notch 11. The cross beam 1, having rubbed at the point of support, falls, turning in joint 2 in the direction of the arrow (see Fig. 2). In the lowered position, the transverse beam 1 does not prevent the frame 12 from passing over it. The array 17 is cut with cutting strings 15.

After the passage of the frame 12 above the transverse beam 1, the curved guides 16, in contact with the roller 6, raise the beam

1 to its original position, while the roller 8, after passing through the notch 11, due to the twisting of the two shoulders lever 4 between the supports 10, rests on the longitudinal beam 3 and thereby fixes the position of the transverse beam 1.

The device can be designed in such a way that the frame with curved guides is fixed, and the tray with the array is movable. However, the nature of the interaction of all components and parts in this case is fully consistent with the above.

Subject invention

A device for cutting an array of cellular concrete, comprising a pallet with transverse and longitudinal beams, a frame with tensioned cutting strings, a drive for moving the frame, and a device for raising and lowering beams, characterized in that, in order to simplify the design and increase reliability of operation, it is provided with two shoulders levers with horizontal axes and rollers at the ends, globally fixed on the crossbeam, and curvilinear guides mounted on the frame and in contact with one of the rollers of the two shoulders Agov, and the other arm of the rollers are simply supported by longitudinal beam pallet.
