(54) INSTALLATION FOR LAYING A BRICK ON A HEATED TRAILER

a kind of rack pushers 3, a mechanism for forming a gap between rows of bricks 4, a chain steel 5, a walking mechanism 6,

tilter 7 and mechanism 8 for transferring the layer of brick to the kiln car.

The elevator serves to lift the cage with a brick loaded with a drying trolley 9. The leveling mechanism of the drying racks is located in front of it. lift and contains levers No 12 fixed on the shaft 10, as well as shields 13, the lower ends of which are hinged on the foundation, while the upper ends are hinged to the rods 14 connected to the levers 12. The roller 15 is fixed on the stand to interact with the lever 11. The mechanism for the formation of gaps between the rows of bricks is made in the form of a table consisting of a central section 16 and two sliding support sections 17 mounted movably in a horizontal plane relative to the central section. A bar 18 is fixed on the latter, the distance from which to the edges of the section is equal to the length of the brick. The sliding sections are driven by pneumatic cylinders 19, on the rods of which: spring-loaded pushers 20 and bolts 21 fixed above the sliding sections are fixed. T gi are movably mounted in kerchiefs of 22 sliding sections and have on their own; the ends of the stops 23.

Two blades 24, alternately moving rows of bricks, are attached to the chain pusher.

The step mechanism consists of fixed

 slats 25 and movable slats 26. The latter are located in horizontal guides 2 7 movable in a vertical direction. A vertical movement of the guides is provided by the cam mechanism 28. In addition, the movable bars are connected through the systems of the pulleys and levers to the connecting rod and crank 29, which sits on the shaft 30.

The cantokovator is made in the form of a chain hobweier 31 with shelves 32. Cuts are formed in the shelves, into which movable

strips of the step mechanism. The turntable is driven by an electric motor 33, through a shaft 34, a crank mechanism 3, and a ratchet mechanism 36. The shaft 34 is connected to the shaft 30 of a sleeve-and-shaft coupling 37, controlled via an air cylinder 38.

The layer transfer mechanism includes a carriage with a group grip, 40, mounted above the horizontal portion of the turn-off device 41.

The installation works as follows. The drying cart with bricks rolls into the crate. When the cage is lifted by the lift 1, the roller 15 acts on the lever 11, as a result of which the shaft 10 with the lever 12 rotates and with the help of tg 14 the upper ends of the shields 13 approach each other. At the same time, the latter interact with the shelves of the trolley and align their ends. Then the cage is lowered by the lift. When the cage is stopped, the pushers 3 supply four rows of bricks from the shelves of the trolley to the mechanism for forming a gap between the rows, with two rows of bricks on each side of the bar 13. The pneumatic cylinders 19 are activated, which, with the spring-loaded pushers 20, press all rows of bricks to the strip 18. The sliding sections 17 move to contact with the central section 16. When the rods of pneumatic cylinders 19 are retracted, ti 21 pass through the gussets 22 before the stops 23 interact with them. Further movement of the rods of pneumatic cylinders 19 causes the sliding sections 17 to mix, each of which has over a row of bricks, before a gap is formed between sections 17 and section 16. iB, as a result, a required gap is formed between these rows of bricks and the rows adjacent to the strip 13, which in turn provides a gap between rdamy bricks. When the chain pusher 5 operates, its blades 24 alternately move the brick rows from the mechanism for forming the gap 4 to the walking mechanism 6. In this case, the bricks of each row have their central part on the movable plate 26, and their edges on the fixed bars 25, Cam mechanism 28 provides for the vertical movement of the movable bars 26, at the same time through a curvature 29 and a system of levers and a pull bar to the bars 26 is given a back and forth motion. As a result, the bricks are raised above the non-leviable strips 25 and individually transferred to the shelves 32 of the turn-off device 7. Thus, the required gap between the bricks in the row is formed. During the reverse movement of the movable bars 26, they lower and the bricks remain on the fixed bars 25. During this time, the chain 31 of the turn-off device 7 moves one shelf by means of a crank rod 35 and the ratchet 36. When moving the chain of the turn-off device 7 from the vertical section to the horizontal 41 brick is converted from a spoon position to a bed position. When a required amount of bricks is accumulated in rows in a horizontal section, i.e. when a layer of bricks is formed, group capture 40 enters into the work and transfers the layer to the furnace car. The formation of the heading of a stack of bricks on the kiln car is controlled by the command device 39, which signals the pneumatic cylinder 38 to disconnect the coupling halves of the hub-and-finger coupling 37. the number of bricks in the district. After the stack has been formed, the command device 39 gives a signal to the cylinder C to turn on the coupling 37, and the walking mechanism 6 comes back into operation without interruption. Subject of the Invention An installation for laying brick on a kiln car, comprising a mechanism for selecting a brick from a press, a tilter, a transfer device and a device for forming gaps between rows of bricks with sliding support sections, which, in order to increase the productivity of the installation, sliding support sections are equipped with power cylinders, each of which is connected to a spring-loaded pusher located above the section, and with the rods installed along; The movable section is in sliding sections and provided with stops at the ends, with a fixed central section between the sliding sections with a bar fixed on it, the distance between which and the edges of the section being equal to the length of the brick.
