Description

This invention relates to precast concrete production lines and reinforced concrete,

The aim of the invention is to increase the productivity of the line by increasing the throughput of the heat treatment chamber, simplifying the design of the J and the form carriages,

Fig. 1 is a schematic side view of a manufacturing line for manufacturing building products; in FIG. 2, the same plan view; in FIG. 3, node I in FIG. 1; in FIG. 4, node II in FIG. 1; FIG. 5 is a section A-A in FIG. 3; FIG. 6 is a view B of FIG. 5,

The technological line for the manufacture of building products contains posts 1–3 installed in a technological sequence with molding equipment, a chamber, 4 heat treatments, and posts 5–7 with preparation equipment. Posts 1 and 2 are equipped with vibrating plates 8 and a paver 9, post 3 with a smoothing machine 10, post 5 with a device for opening the boards I1, post 6 with a tilter 12. and post 7 with a device for closing the boards 13, On the line there are guides 14 for mold cars 5, At posts 1 - 3, parallel to the guides 14, guides 16 are installed for the paver 9 and the smoothing machine 10,

In the heat treatment chamber 4, parallel guides 14 in the upper part are laid guide rails 17 having the same gauge with guides 14. In front of the guides 17 (Fig. 3), L-shaped forks 18 with guides are mounted in the heat treatment chamber 4 19 of a lifting device 20 having a shaft 21 placed outside the chamber through a shaft 21 installed in supports and at the end of which a rocker 23 rigidly fixed, an actuator 24 pivotally connected to it. The second arm of the rocker arm 23 is pivotally connected to a rod 25 which has a second end but coupled with the lever 26 rigidly fastened to a shaft 27 which is mounted in bearings 28 fixedly mounted on the frame 4, the heat treatment chamber. At the opposite end of the shaft 27 is fixed rigidly | 29, pivotally connected with the help of t, 30 to the lever 31, which is rigidly fixed

 Replen on the end of the shaft 32 installed in the supports 33. At the opposite end of the shaft 32 is rigidly fixed the second L-shaped forks 35.

5 The design of the lowering device 34 is similar to the lifting device 20. The reducing device 34 is also equipped with an L-shaped forks 35 with guides 36 for

 About trolley forms 15,

In the center of the heat treatment chamber 4, a chain conveyor 37 (FIG. 5) is fitted in the upper inner part, equipped with carts 38,

tS each of which has a folding stop 39, Conveyor 37 has a DRIVE 40, which is placed outside the chamber 4 of heat treatment, In the ends of the chamber 4 of heat treatment, the flaps 41 with the actuator 42 are mounted on the ends (figure 4),

At the technological posts on either side of the heat treatment chamber, carriage receptacles 25 of water 43 with pushers 44 for form-trolleys are provided.

The technological line for the manufacture of building products works: as follows.

At the post I, the texture layer was laid and the reinforcement cages were installed, in post 2, the concrete was laid and compacted and the mortar layer, and in post 3, the upper surface of the product was smoothed, and vibrating plates 8 were used. The pavers 9 and the smoothing machine 10. After completing all the operations of the form-trolley 15, located at these posts, are moved by the actuator 43 by one step, while the form is located at post 3, Enters the heat treatment chamber 4, where before this the form-trolley 15, located in front of the lifting device 20, it grabs its rollers with the L-shaped forks 18, which rotate through the shaft 21 mounted in the supports 22, and the rocker arm 23 from the actuator 24. At that time, through the shaft 25, the roller 26, the shaft 27 rotates in the supports 28, the lever 29, the tension 30 and the shaft 32 rotating in the supports 33 synchronously rotate the gripper 18 located on the opposite side of the mold, which after elevation is set into an inclined position, and

,,

grippers 18 occupy horizontal -. position; however, their guides 19 are stitched to the upper guides 17 of the heat treatment chamber 4.

At the same time, the drive 34 of the lowering device is turned on, its L-shaped forks 35 with the guides 36 are placed in a horizontal position, while the guides 36 are aligned to the guides 7 of the heat treatment chamber. The drive 40 of the chain conveyor 37 is turned on, which, by moving the carriage 38 by means of the stops 39, which come into contact with the stops of the form-trolleys 15, located obliquely in the heat treatment chamber, moves them along directions to a predetermined pitch.

enters the guides 36 on the prepared grippers 35,

The actuator 34 of the lowering device is turned on and the form trolley 15 is lowered to the guides 14 in the horizontal position. After this, the actuator 42 is turned on to raise the flaps 41 to the upper open position. Form-trolley 15 from post 7 is transferred by crane to post I, turn on drive 44 and move form from chamber to post 5, form from post 5 to post 6 and form from post 6 to post 7. Processes are performed at posts 5-7 - opening of the sides, removal of the product, cleaning, lubrication of the car forms, closing of the sides,

After all the work has been done, the cycle is repeated.
