Description

one

The invention relates to the field of construction and can be applied in plants for the production of precast concrete, in particular for pushing and retracting the sides of form trolleys in the manufacture of products with a complex profile of end surfaces and the presence of reinforcement.

Devices for demolding and assembling form carriages are known, consisting of hydraulic cylinders and a system of levers. The opening and closing of the sides of the forms is made by turning them relative to the charlars mounted on the form tray. However, such a device cannot be used for the removal of products with complex end surfaces and long releases of reinforcement. To disassemble such products, the bead of the mold must be moved back.

The purpose of the invention is to create a device that allows to mechanize the process of moving aside and retracting transverse bortovom-trolleys in the process of demolishing during conveyor production of concrete and reinforced concrete products with complex face surfaces and fittings, while at the same time improving the quality of these products and reducing the number of defects.

The device consists of identical in design mechanisms of moving aside and pushing the sides, which are fixedly located at the dismantling station of the conveyor line, so that when the form-trolley is fed to this post, the hooks of the transverse sides located along

their ends are set against the grips of the respective mechanism. With the simultaneous switching on of all the mechanisms of the stripping, the grippers, moving along the bearing surface of the guide brackets of the STANINES, engage with the hooks of the transverse sides of the form-trolley and move both transverse sides to a predetermined distance. During the reverse movement of the grippers, the sides are pushed in, after which the grapples are automatically set by the action of the springs to their original position.

FIG. 1 shows the stripping mechanism in the plan; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 - a device for dismantling and assembling forms of trolleys, general view; in fig. 4 is a section along BB in FIG. 3

The device consists of separate structurally identical mechanisms for moving the transverse sides, which are not located at the corresponding post of the conveyor line. The stripping mechanism itself contains a frame 1, a power cylinder 2 hinged on it, guide sleeves 3, movable columns 4 connected to

one side of the bracket 5, the other

traverse 6, on which there are lugs 7 with an emphasis 8, where on axis 9 a gripper 10 is installed, having a pin 11 and a spring 12, which presses the gripper 10 on a support surface of a guide bracket 13 rigidly located on a bed 1. On columns

4, springs 14 are installed, the force of which is adjusted by nuts 15.

When the trolley form is fed to the post, the form-dismantling post is fixed on the conveyor track so that the hooks 16 of the transverse sides are installed with a gap opposite the grippers 10 of the respective mechanisms. In the initial position, each gripper is pressed by the spring 12 to the inclined part of the bearing surface of the guide bracket 13.

At the same time turn on the power cylinders 2 of all the mechanisms of stripping, the rods of which, moving forward, are moved with brackets

5 columns 4, and they, in turn, move the yoke 6 and, accordingly, the eye 7, the axis 9 and the grip 10 relative to the frame 1 and the guide bracket 13.

Due to the bend on the bearing surface of the guide bracket 13, the gripper 10, moving, rotates until the finger 11 touches the stop 8 on the axis 9, overcoming the force of the spring 12, and simultaneously engages with its slot in the transverse bead 17 of the form-waggette 18, moves it, tearing; from the product and release from rebar releases, after which all power cylinders of the 2 stripping mechanisms are simultaneously shut off.

Thus, the lateral sides of the form of the car are pushed back. After the longitudinal sides are removed by known methods, the product is removed from the mold.

Then the trolley shape is cleaned, lubricated, and rebar installed.

After that, the sides are moved in (form assembly) in the reverse sequence, i.e. the power cylinders are turned on, the rod begins to move in the opposite direction, respectively, moving column 4, yoke 6, eyelet 7, axis 9 and gripper 10 engaging with a transverse bead hook 16. As a result, the transverse beams of the trolley form are set to their original position. The syphilic cylinders 2 are shut off, while their cavities remain unzagged. - ... ;

Under the action of the force of the springs 14 ,, of the boom box 4, they move back along with the rod of the ram 2 and the claw 10, which under the action of the springs 12 deflects and lays its lower surface on the inclined part of the supporting surface of the guide bracket 13, transversely engaged with the hook 16 The beads 17, i.e., become in a neutral position, providing a guarantee gap E for the passage of the form-trolley 18 along the rail tracks of the conveyor line between the stripping mechanisms.

Subject invention

A device for demolding and assembling form-shaped cars, including mechanisms for moving transverse and longitudinal sides mounted on a stationary base, characterized in that, in order to mechanize the process of conveying products with a complex profile of end surfaces and increasing productivity, each transverse board is equipped with hooks, crossboard

made in the form of a housing with an emphasis and guide bushings, in which columns equipped with springs, connected at one end by means of an arm with a moving drive, and to others

The ends are rigidly attached to the yoke, on which a spring-loaded gripper interacting with the stop is mounted so that it can be rotated and connected to the bead hook.
