Abstract

The essence of the invention: the trolley-form comprises a pallet 1 with hinged beads 2 and 3 and rests on wheels 21. The stops 5 and b in the form of L-shaped levers are hinged attached by means of brackets to the sides 3 and 2 and have stepped protrusions 7. The center of the pallet 1 is rigidly fixed with a vertical rod 12, on which a spring-loaded coupling 15 is installed. The coupling has grooves in which the ends of the levers 5 and 6 are inserted. In the lower part of the coupling 15, rollers 17 are mounted, which contact with the ground stops 19 open rmy in the form of stripping. 9 il.

The invention relates to the manufacture of building structures and can be used on conveyor-flow lines.

The purpose of the invention is to increase the efficiency of use and simplify the design of the trolley form by combining the functions of moving and locking the sides.

Fig. 1 shows a trolley for manufacturing building products in the closed position of the boards without a pallet designation, a plan view; in fig. 2 - the same. in open position; in fig. 3 - form-trolley, front view; in fig. 4 - the same, side view; in fig. 5 - the same, in the open position. Boards at the post of assembly and stripping of forms; in fig. 6 - the same, at the time of closing the sides of the form; FIG. 7 is a section A-A in FIG. one; in fig. 8 - the same, in the open position of the sides; in fig. 9 shows a section BB in FIG. one.

A trolley for the manufacture of concrete products consists of a pallet 1 with molding boards 2 and 3 installed on it, to which the L-shaped levers 5 and 6 with stepped ledges 7 are hingedly attached with brackets 4. Boards 2 and 3 with brackets 8 and 9 are hinged to the pallet 1. The channels 10 of the pallet 1 have slots for the passage of the L-shaped levers 5 and 6. In the center of the pallet 1, in its lower part, a vertical rod 12 is rigidly fixed on the plate 11, on which by means of a key 13 is fixed from circular rotation, and when the spring 14 is pressed into the lower position of the coupling 15. At the base of the coupling 15, on the axis 16, the support rollers 17 are attached. trolley forms. The pallet 1 is made on wheels 21, with which it moves along rails 22 of the conveyor line.

A trolley for manufacturing concrete products works as follows.

After compacting the molded product 18 on a vibrating plate (not shown) and a thermo-humidifying treatment, the trolley mold with the product is fed to the demolding station and

form assembly. In this case, the support rollers 17 are in a free state, the coupling 15 is pressed by the spring 14 to the lower position, the stepped protrusions of the 7 L-shaped levers

5 and b are in connection with the top of the grooves of the coupling 15, the beads are closed.

Upon receipt of the form-trolley at the demolding station, the support rollers 17 come into contact with the ground stop 19 open

sides and squeeze the spring 14, moving the coupling 15 to the upper position. In this case, the stepped protrusions 7 of the levers 5 and 6 exit from the joint with the grooves of the coupling 15, thereby removing the beads 2 and 3, and

further elevations of the coupling 15

side stepped protrusions 7 levers 5

and 6 comes into contact with the bottom

grooves and the opening of the boards 2 and 3.

After removing the molded article 18 and cleaning the mold, the sides are closed. This is done as follows. Upon further movement of the trolley shape along the conveyor, the support rollers 17 come into contact with the ground L-shaped stops 20 for closing the sides, and with their inner part, the profile of which allows the coupling 15 to return to its original position. This also contributes to the spring 14. Upper part of the grooves

the clutch 15 enters the connection with the stepped protrusions 7 of the G-shaped levers 5 and 6. Due to this, as well as the action of the spring 14 and the weight of the L-shaped levers 5 and 6, the beads 2 and 3 are reliably fixed

working position.
