Description

. This invention relates to the process equipment used in cassette installations for the production of concrete products.

A device for locking the thermal walls of a cassette installation is known, consisting of a movable vertical bar with wedge elements fixed in height, earrings with holes for the wedge elements, and a drive for vertically moving this vertical bar SP.

The disadvantage of this device is its complexity and the need for additional mechanisms for fixing the thermal compartments and their movement, as well as their insufficient tight connection with each other.

The purpose of the invention is to simplify the cong struction of the device and increase the reliability of the connection of the tekhkzvyh walls.

This goal is achieved in that the device for locking the thermal walls of the cassette installation, consisting of a movable vertical bar with wedge elements fixed in height, earrings with holes for wedge elements and a drive for the vertical movement of this vertical bar, is equipped with nojq wedge brackets and horizontal fixed rods with lugs, each of the wedge elements is made with a speaker, interacting with the fixed rods, and the mechanism for moving the vertical Flax rod - in the form of a screw pair.

FIG. -1 shows a device

15 general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. - cassette installation, general view.

The device contains composite va2y ly 1 with shanks 2 with screw 3 fixed on them. Shafts by means of bearings k fixed on the ends of thermal walls 5- Screws 39

act with nuts 6, which are tightly Attached wedge elements 8 with protrusions. Staples 9 in which the protrusions of the 7 wedge elements are moved are rigidly attached to the ends of the thermal walls. Above the brackets 9 along the ends of the heat walls 5, horizontal movable bars 10 are placed with supports 1 1 fixed to them. Bottom brackets are fixed ti gi 12 with holes.

Trolleys. 13, the hydraulic actuators 1 are connected by movable links 10 and move along the upper 15 and lower 16 guides. The fixed rods 12 are mounted on a fixed thermal wall 17. The drive shafts 1, on which the device screws are fixed, consist of a movable portal 18, on which rotation mechanisms with grippers 20 are moved by means of hydraulic cylinders 19 and are engaged with the shanks 2

The device works as follows.

At the beginning of operation of the cassette installation, the bag from the heat walls 5 is in the right extreme positions, and the protrusions 7 are moved to the lowest position with screws 3 and their parts are below the stops 11 of the movable tubes 10.

After cleaning the first left thermal bar, fixed wall 17 and fitting the fitting with the gripper 20, the drive of the screw pair is introduced into engagement with the shank 2 of shaft 1 fixed to the first wall.

The drive is driven into rotation by the shaft 1, and by means of a screw pair the protrusions 7 with their upper ends engage with the stops 1 1 on the fixed rods.

By switching on the hydraulic drive, the carriage 13 is moved to the left end position until the first thermal wall closes in with the fixed wall. Simultaneously with the movement of the first

four

The moving thermal wall moves both actuators of the device.

By turning on the reverse of the drive of the device, the nut 6 with the protrusions 7 is lowered

way down. With their projections, the wedge elements engage with the holes of the fixed tubes and tightly lock the first thermal wall with the fixed wall.

After that, the drive is disconnected from the shank 2 of the shaft 1, is moved to the right, connected to the shank of the shaft of the second thermal wall, and the cycles are repeated until all

the walls will be moved to the left position and securely closed with wedge elements inserted into the holes of the fixed tons.

After filling the cavities with concrete, vibrating and heat treating, the opening of the thermal walls and their movement to the extreme right of the bed is carried out in the reverse order of the movement and locking of the thermal compartments.

The invention The device for locking the thermal walls of a cassette installation, consisting of a movable vertical rod

with wedge elements fixed in height, earrings with holes for wedge elements and a drive for vertical movement of the rod, which is characterized by the fact that

In order to simplify the design of the device and increase the reliability of the connection of the heat walls, it is equipped with guide brackets for wedge elements and horizontal fixed rods with stops, each of the wedge elements made with a protrusion interacting with fixed rods stops, and the form

screw pair.
