Description

The invention relates to the manufacture of concrete products in cassette forms.

Installations are known that contain a support frame, dividing partitions on support systems, airborne equipment with feed cones, vibration devices, and displacement mechanisms [1].

The closest known solution is an installation comprising a frame with guides for moving by means of a drive of the molding-thermal walls, an assembly mechanism, a molding device, a stripping mechanism, cleaning and lubricating the compartments, a device for laying reinforcement cages and tilters for turning the vertical thermal walls into a horizontal position and back [2].

The disadvantages of the known installations are the need to have additional space to accommodate tilters and ways to return the thermal compartments.

The purpose of the invention is to reduce the production space required for the installation of the installation.

This goal is achieved by the fact that the installation for the manufacture of reinforced concrete products

in cassette forms, containing a support frame with parallel beams with guides, thermal walls with support rollers and locks, mechanisms for moving and tilting thermal walls, locking and opening locks, a concrete paver with a drive of vertical movements, is equipped with additional beams located in the upper part of the frame over the thermal walls, and the tilting mechanism is made in the form of y-shaped inclined guides with a pair of spring-loaded articulated levers, each of which has m end hinge latch.

FIG. 1 shows a general view of the mouth of the ¹⁵ ; in fig. 2 - node I; in fig. 3 - view A; in fig. 4 - node II.

The installation includes a frame 1, made in the form of a spatial metal structure with upper and lower beams 2, on which guides 3 and beams 4 are mounted, on which guides 5 and 6 are mounted. On the ends, tilters 7 and 8 are mounted.

The installation is equipped with heat-forming walls 9, made by rollers K) and locking mechanisms 11. On the guides 6 a self-propelled machine 12 for cleaning and lubricating the molding surfaces of the walls 9 is installed. On the frame 13, smoy ί sh. 15. On the frame 1. in accordance with the location of the locking mechanisms 11, arranged in pairs are mechanisms 16 for locking locks 11 and mechanisms 17 for opening these locks. Between the beams 4, a transport mechanism is mounted in the form of a step plunger 18. It is made in the form of movable reciprocating rods with retractable supports interacting with the ends of the walls 9. In addition, the feed mechanisms 19 and the form-removal mechanism 20 are mounted on the frame 1.

The tilting mechanism 7 consists of two guides 21, inside which are located the screws 22 and gripping heads 23. made in the form of a nut, screwed onto the screw 22, and guides 24 with a locking mechanism, made in the form of a swinging double-arm lever 25, driven by a power cylinder 26. Drive screw 22 in the rotational movement is carried out from the gearbox 27, with the output shaft of which the screw 22 is connected by a coupling.

The guide 21 is connected in its upper part with the guide 5 of the beam 4, and in the lower part with the guide 3 of the lower beam 2.

Each of the gripping heads 23 is provided with a latch 28 connected with a spring-loaded lever 29 of an articulated lever system formed by the lever 29, the plunger 30, the lever 31 and the spring 32. A stop 33 is fixed on the guide 21.

The installation works as follows.

Horizontal wall tangent 7 wall 9 is installed on the guides 5, along which it is pushed with a given step in the direction to tilter 8 step pusher 18. During the pushing process, the molding cavity of each wall 9 is cleaned and lubricated by the machine 12 and charged with reinforcement. In the process of pushing rollers 10 walls 9 fall into the guides tilter 8, which produces the tilting of the wall 9 in a vertical position. After this, the wall 9 is captured by the gripping body of the feed mechanism 19, which presses the wall 9 to the bag previously assembled from the wall 9. When the wall is pressed to the bag, the locking mechanisms 11 of the wall 9 are articulated with the locking mechanisms of the previous wall 9 previously attached to the bag. the locking mechanism 16 produces a wall tie 9 with a previously assembled package of walls, followed by a mold

Naya cavity of the wall 9 is concreted by means of a lifting paver 14.

At the end of the molding, the paver 14 rises to the extreme upper position to pass to the tilter 8 of the next wall 9, loaded with reinforcement.

After concreting, the wall 9 is connected to the coolant (steam) and the heat treatment of the molded product is performed. The heat treatment is performed until the wall 9 reaches the dismantling post located in front of the tilter 7. At the dismantling post, the wall 9 is disengaged from the wall package through the mechanism 17 for opening the locks 11 and disconnected from the heat carrier (pair) and the product is disassembled, after of which the wall 9 is turned over by the tilter 7 from the vertical position to the horizontal one and is mounted on the guides 5.

The tilting of the wall 9 on the tilter 7 is as follows. After separation of the wall 9 from the package, the latter mechanism of stripping 20 is fed to the tilter 7, while the lower rollers of the vertically positioned wall 9 press the latches 28 and roll onto the supporting surfaces of the gripping heads 23 located inside the guide 21, and the upper rollers - into the groove of the guide 24 At this moment, the lower shoulders of the levers 25 are in the folded back. a position allowing free passage of the upper rollers to the groove of the guide 24. After the upper rollers of the wall 9 enter the groove of the guide 24, the locking mechanisms move the levers 25 to a position in which the lower ends of the levers 25 overlap the slots of the guides 24 and the upper ends of the levers 25 exit the slot of the guide 24. After that, the rotational drive of the screws 22 is turned on, as a result of which the gripping heads 23, moving along the screws 22, carry along the rollers which are engaged with them, and the other rollers of the wall 9 at this time move inside As a guide 24, and go to the support surface of the guide 5. After the rollers are engaged with the gripping heads 23, the stop 33 lowers the latches 28 to the level of the supporting surfaces of the gripping heads 23, and the locking mechanism will move the levers 25 into a position in which its upper ends overlap the grooves of the guides 24 and create support for the rollers that were engaged with the heads 23. After that, the step plunger 18 moves the wall 9, edged in a horizontal position to the preparatory technologies -meteorological positions, ie. e. the installation work cycle is repeated. The work of the tilter 8 is in reverse order with respect to the work

tilter 7, because tilter 8 translates the wall 9 from a horizontal position to a vertical one.
