The invention relates to the construction industry, namely to factory process equipment intended for the conveyor production of building products.

A known conveyor line for the production of building products, comprising form-trolleys and technological equipment for the manufacture of reinforced concrete slabs l.

The closest technical solution is a conveyor line for the manufacture of reinforced concrete products, containing trolley-forms installed by rolling bearings on rail guides and equipment arranged in a technological sequence, consisting of devices intended for cleaning, lubricating, placing concrete into a trolley-shaped mold. , vibration treatment and finishing, the heat treatment chamber of the molded products, the heatsinker and the mechanism for moving the trolley forms along rail guides 12.

The disadvantage of these conveyor lines is their low productivity, which means a considerable expenditure of working time during

assembling and disassembling the dismantling of the form of the wagon.

The difficulty of stripping is to accurately position the shuttering nests of the trolley-form above the pushers of the vypressovshchiki, which requires considerable time, since this prevents the inertia of the movement of a large mass of the 10-trolley with the product.

The purpose of the invention is to increase the productivity of the conveyor line.

This goal is achieved by the fact that a conveyor line for the production of reinforced concrete products, containing forms-trolleys, installed by rolling bearings on rail guides and equipment, located in the processing sequence, consisting of devices intended for cleaning, lubricating, laying concrete into forms - trolleys, vibroprocessing and finishing, heat treatment chamber molded

25 products, a demolisher and a mechanism for moving the trolley cars along rail guides, it is equipped with turning devices, one of which is installed at the exit of the forlil trolley

30 from the heat treatment chamber, and the other after the device for lubrication, each of which is made in the form of connected parallel frames, at the ends of which rail guides and stops are fixed for fixing the form-trolley inside the turner, and the heater is made in the form of a U-shaped frame with mounted on it spring-loaded air breakers, and means for removing finished products, mounted under the U-shaped frame, while the device for cleaning the trolley forms is made in the form of a series of nozzles fixed on the pipeline supply of compressed air, and for lubrication - nozzles for supplying emulsion to the machined surfaces of the form-trolley.

In addition, in order to reduce energy consumption, rail guides between tiltings are inclined towards the side of the spacers, and are equipped with movable locking devices for positioning the form-cars at the locations of the process equipment, the means for removing finished products from the spacers is a belt conveyor, pallet the trolley molds are made with the ability to change their shape during demoulding.

FIG. 1 shows a conveyor line, general view; in fig. 2 is a continuation of this line in FIG. 3 - formavagonka in the plan; in fig. 4 - forms of car, section A-A; Figure 5 is the same, section BB; in fig. b - tilter j in FIG. 7 - the same, section bb; on Fig - ejector device.

The conveyor line for the production of concrete products consists of concrete paver 1 with vibrating nozzle 2 and finishing device 3, drawing conveyor device, mold 4, heat treatment chamber 5 b, ejector 7, cleaning post 8, lubrication post 9, conveyor conveyor 10, rail ways 11, cumulative tapes 12 and crane 13.

The main conveyor device is located in a special niche of the trench 14, which passes under the concrete paver 1 and under the heat treatment chamber 5 and consists of a drive station 15, a tension station 16 and a pull chain 17, on which links stops are fixed with a certain step (not shown ), which capture the form-trolley 4 and move them along the rail track m 11.

Form-trolley 4 (Fig.3-5) are made of sheet and section rolled with non-separable sides.

For the rigidity of the trolley-form 4, a support box 19 of the box-shaped jamb is welded to its pallet 18 with outposts. Along the ends of the trolley 4 on the stop 20 and the carrier beam 19, wheels 21 are installed, two on each side. To move the trolley along a rail track 11.

Guides 22 are welded to the pallet 18 and the beam 19, in which ejector pins 23 are installed, made in the form of pins with heads made flush with the carriage 18 of the carriage 4. To obtain decorative and technological grooves on reinforced concrete products, rubber plates are mounted on the pallet of the form.

Paver 1 serves to distribute, compact and smooth the concrete mix.

The tilter (Figs. 6 and 7) is a quadrangular welded frame 24, in the end parts of which two semi-axes 25 are welded, mounted in rolling bearings 26 on racks 27. On one of the semi-axes 25 there is fixed a pulley 28 on the device 29. On the frame 24, rail rails 30 are fixed, which are extensions of the rail tracks 11. Rail rails 31 are mounted and at the top of the frame 24, so that when the chassis 24 is turned to turn the rail rails 30 and 31, the rail rails 31 join with the inclined rail P 11. At the ends of the guide rail 30 mounted abutments 32 with limit switch 33. The limit switch 34 is mounted under the guide rail 30 and a switch 35 - the beginning of the inclined track 11.

The detachment post from the trolley form (Fig. 2) is intended to release products from the trolley forms and contains a tilter and an ejector. The ejector is a welded box-shaped beam 36, which rests on the supports 37 and along which there is a row of pushers made in the form of spring-loaded shoes 38. The position of the shoes 38 corresponds exactly to the position of the pushers 23. A roller is installed on the top of each shoe 38 39 which is affected by a wedge 40. The wedge 40 is mounted on an axially movable axle 41, the movement of which, and with it the wedges 40, is carried out by a winch 42 with a cable-block system 43. Turning on caustic 42 is carried out limit switch 44 mounted on the track 11, which acts on wheel 21, forms the trolley 4.

On block 36, two levers 45 are mounted, which are intended to stop the trolley 4 and which are at one end hinged on the beam 36, and in the middle part are also hinged on the tractor 41. The transport carriage 10 moves under the clearance post.

The production of concrete products on the proposed conveyor line is carried out as follows.

From the cassette 12 installed at the beginning of the conveyor, three forms G-trolleys 4 roll down the inclined path to the stops of the heavy conveyor. The drive station 15 is turned on, the thrusters of the thrust chain 17 capture the shapes of the wagon 4 and, along the track 11, feed it to the vibrating nozzles 2 of the paver 1.

Pre-in the form of trolley 4 lay the necessary fittings and inserts. The paver 1 mechanisms are turned on - the screw drive and the vibrator drive, the paver 1 drive along the transverse track and the move-separator drive 3 with smoothing roller along the guides along the product.

The operation of the paver 1 and the finishing device 3 is carried out according to an automatic cycle.

When the next trolley-form 4 moves under the paver 1, it is in the extreme position, and its vibro-slips are above the spring-loaded pallet, which in this case plays the role of a damper preventing the concrete from coming out. When the forma-trolley 4 exactly fits under the paver 1, the locking mechanisms accurately fix its position, and the limit switches turn on all the mechanisms (not shown).

After placing and vibrating the concrete of the form-trolley 4 by moving the lower conveyor one step under the rotating smoothing roller, the next movement of the finishing device along the guide roller smooths the surface of the product, and the next empty form-trolley 4 is installed under the guide roller.

At the same time, the other trolley forms located on the conveyor belt enter one by one into the heat treatment chamber 5. From the heat treatment chamber of the trolley 4, one by one is fed by a pull chain 17 on the slide and rolled to the next post of the line to the turner 6.

By pushing the wheel 21 to the stop with a limit switch, the trolley form turns on a turn-off device that rotates the mold with the product at a given angle leo, and then the trolley mold is fed under the ejector device, where it is removed from the article by means of pushers 38 and sent via cart 10 , product to the warehouse, and trolley 4 by

inclined path 11 enters the post 8 cleaning, and then on post 9 lubrication.

The cleaned and lubricated trolley 4 along the inclined track 11 enters the second tilter b, turns over to its original position and rolls into the collecting cassette 12.

After filling the cassette 12 with three cleaned and lubricated trolley forms 5, the cassette is transferred by crane 13 to the paver 1.

The advantage of the proposed conveyor is that the post-assembly and repair of formwork, a number of manual operations are eliminated, the production areas are freed up.
