Description

I

The invention relates to the construction industry, in particular to equipment for the manufacture of concrete and reinforced concrete products.

A double-shaped form to the rotor conveyor is known, made in the cross-section in the form of a wedge, comprising a tray and a thermal compartment 1.

When extruding the mold from the cavity of the rotary conveyor, the concrete product is displaced along the tangent to the walls of the conveyor cavity, which increases the effort required for pressing and also increases the requirements for the quality of the conveyor surfaces.

The purpose of the invention is to facilitate the removal of the mold from the cavity of the rotary conveyor.

It is achieved by the fact that in the form containing the pallet, made in the cross section in the form of a wedge, and the thermal compartment, the latter is made of a composite of two parts, and the pallet is provided with a wedge interposed between the parts

thermal compartment, with the wedge and the thermal compartment on adjacent surfaces made respectively with rows of T-shaped grooves and T-shaped sliders with rollers.

In addition, the wedge is made with spring || to xators, in order to prevent the movement of thermal compartments relative to the influence in the molding process. .

FIG. 1 shows a general view of a rotary conveyor with a form in plan; in fig. 2, section A-A in FIG. in fig. 3 is a plan form; FIG. 4 is a section BB in FIG. 3; Fig. 5 shows a wedge interface with a warm compartment; in fig. 6 spring-loaded retainer mounted on the wedge.

The form is intended for a rotary conveyor made in the form of a pivoting frame 1 with wedge cavities 2 radially arranged along the perimeter.

Claims (2)

In the cavity of the rotary conveyor, mobile double forms 3, having a kpin shape in cross section, are installed. Each double form 3 is completed; on with a movable wedge 4 rigidly mounted on a pallet 5 forms. Wedge 4 is located between the thermal compartments 6 with airborne equipment. The heat compartments 6 have a rectangular shape in cross section. Adjacent surfaces of the wedge and thermal compartments are made respectively with rows of T-shaped grooves 7 of limited length / about 50 mm / and T-shaped sliders 8 with rollers 9. T-shaped sliders 8 with rollers 9 are placed in T-shaped grooves 7 The wedge 4 is made with spring-loaded latches 10. The empty form 3 rolls and the form with the product is removed from the cavity 2 of the rotary conveyor along the conveyors 11 The molding cavities are formed by test compartments and walls of the corresponding cavities 2 of the rotary conveyor on both sides of the moving wedge 4. Form n moves vertically during concreting with the help of a lift 12. The concrete mixture is fed into the forms from the bins 13. The rotary conveyor with the proposed form is as follows. The completed form 3 is fed along the live rolls 11 into the free cavity 2 of the rotary conveyor and turns out between two rows of hoppers 13 During the installation of the mold 3 in the cavity 2, the T-shaped slide 8 with the rollers 9 are moved up to the stop in the T-shaped driver 7, after which the latches 10 work and the wedge 4 becomes stationary relative to the thermal compartments - 6 The elevator 12 lifts the mold 3. The hoppers 13 are filled with a loaf, the vibrators turn on, and the elevator 12 slowly lowers the mold 3. In the process of going down, the mold 3 from the hoppers 13 is filled with concrete. Further, when the rotary conveyor rotates further, the mold 3 with the concrete is moved through a certain angle, after which thermal energy is supplied to the heat compartments 6 for heat treatment of the concrete. Passing an angle of 360 / minus the angle between the cavities / mold 3, which has undergone heat treatment, stops in front of the roller conveyor 11. With the press 14, the mold 3 begins to push out of the cavity 2 of the rotary conveyor, withdrawing the latches 10 from engaging with the heat compartments 6. At the same time, the force for pressing out the radially directed rotary conveyor is applied to the movable wedge 4, the slider 8 with rollers 9 of which begin to move in the slots 7 of the thermal compartments b. As the cavity 2 moves, the wedge 4 slides the thermal compartments 6 through the sliders 8 -surface, the separation thus molded product from the cavity walls 2 along the normal. In connection with the limited length of the grooves 7, the movement of the heat compartments 6 with the product along the normal to the walls of the cavity 2 is about 10 mm with a slope of one side of the cavity 2 of the rotary conveyor 1/50 h. After the surface of the molded product is detached from the walls of the cavity 2 of the rotary conveyor, 3 rolls out along the conveyors 11 from cavity 2 for passage. further technological operations. Claim 1. A double-rotor form for manufacturing reinforced concrete products, comprising a pallet made in cross-section in the form of a wedge and a thermal compartment, characterized in that a composite of two parts, and the pallet is provided with a wedge located between the parts of the heat compartment, the wedge and the heat compartment on adjacent surfaces having T-shaped grooves and T-shaped sliders with rollers, respectively. 2. A double form of claim 1, characterized in that, in order to prevent the parts of the thermal compartment from moving relative to the wedge during the molding process, the wedge is provided with spring-loaded latches.
