(54) CONVEYOR LINE FOR BUILDING CONSTRUCTION PRODUCTS

I

The invention relates to the construction industry, namely to conveyor lines for the manufacture of building products. Of concrete and other formable masses.

According to the main author. St. No. 768640 is a known conveyor line, which contains a concrete paver, trolley molds and mechanisms predicated for stripping molding, finishing finished products and for moving mold trolleys, and vertical heat chambers. To increase the capacity of the lines, each of the heat chambers is equipped with guides installed in a vertical plane and interacting with the trolley forms, slips, catchers with drives and reducer, and each of the trolley forms with additional rolling bearings fixed to its side surfaces. x, with which it is in contact with the support ps supernovae. my sclyoo. The direction of the heat chamber in the lower part have a roller for fixing the. lorry form-trolley. Each is made of two parts: the upper shaft and the turn and the turn.

The safety device is made in the form of an L-shaped lever, hinged at the bottom

parts of the heat chamber on the discharge side,

one arm of the lever interacts with the form-trolley by means of a roller, and the other is connected to the drive. The dredger is made in the form of a telescopic frame, which is saribarno attached to the drains located below the base of the heat chamber, with the possibility of passing over the sink of the form-trolley (1).

The disadvantage of this conveyor line is that the lower form, bearing on itself the package of forms with products, is supported in a static position by additional

., rolling bearings on the inclined surface of the clutches, which creates a heavy load on the catchers and the lower front part of the heat chamber. When loading forms with products into the heat chamber, additional dynamic loads are applied to the catchers and the front part of the chamber from impact of the installed form onto the bag. This necessitates a significant constructive, amalgamation of the front of the chamber and additional;

constructive solutions to prevent self-rolling of the lower shape and lowering the Btcro of the peta in case of accidental rotation of the catchers at the moment when the reducer does not contact the lower shape. All this reduces the reliability of the line.

The purpose of the invention is to increase the reliability of the line.

This goal is achieved by the fact that in the conveyor line for the manufacture of construction products, the heat chamber is equipped with pushers, and each of the storage areas in the upper part has a straight line section for additional support of the trolley form, with the pushers installed in the chamber on the opposite side of pushing the trolley-form from the straight-line sections of the building.

At the same time, the pusher consists of a base and a two-arm lever mounted on the base, pivotally attached to the slide, one shoulder of which is pivotally connected to the stem of this cylinder, and the other interacts with the form-trolley by means of a roller.

FIG. 1 shows a conveyor line, general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 — node I in FIG. 3; in fig. 5B in FIG. four; in fig. 6 — node AND in FIG. 3

The conveyor line for the manufacture of building products consists of a paver 1, mixed by rail, form carriages 2, chain pushers 3 for moving carriages, post 4 stripping, post 5 molding, post 6 finishing and vertical heat chambers 7. Thermal chamber 7 In the lower part of the front wall there is an opening 8 for unloading the molds, and in the lower part of the back wall an opening 9 for free passage of the forms from the subsequent chambers. Each heat chamber has vertical guides 10, the lower part of which is made with notch II, in which the rollers 12 are mounted.

Each forms a-trolley 2 is provided with rollers 13 for movement along a track and additional rolling bearings 14 located on its side surfaces. On the front wall of the chambers 7 above the opening 8 a safety device is installed, made in the form of a spring-loaded L-shaped lever 15, one arm of which is connected to the hydraulic cylinder 16, and the other is provided with a roller 17 for interacting with the form-trolley. The bottom trolley-form contains additional supports 14.

Based on the heat chambers, fixed slides 18 with a rotary part 19 are installed along rail rails. A hydraulic snubger, made in the form of a telescopic fixed 20 and movable 21 frames and a hydraulic cylinder 22, is mounted on the movable frame of the heat chamber. grip 23. The fixed frame 20 with support 24 is pivotally fixed on the base with mka.,

The stationary skirts 18 are made with horizontal sections 25, on which a form-trolley is installed with its additional rolling support.

In the lower zone of the heat chamber on the side opposite to the unloading, ejectors are placed, each of which is made in the form of a two-arm lever 26, hinged on the slide 18, with one lever arm connected to the hydraulic cylinder 27, and the other is provided with a roller 28 for interacting with the trolley shape .

Conveyor line works as follows.

At post 4 of the formwork, cleaning, lubrication of the trolley mold and preparation of it for molding are performed. By the pusher 3, the trolley form is fed to the post 5 of the molding, molding is performed, and then the mold with the product enters the post 6 of the finishing. At post 4 of the stripping at this time J, the next trolley form is being prepared. After finishing, the mold with the product is fed by a crane to the heat chambers 7, which are gradually filled with forms of trolleys, each subsequent being supported by rollers 13 on the lower one, and the trolley forms form a bag.

After passing the time specified for heat treatment, the bottom trolley form is unloaded from the steam chamber in the following manner.

 The lower trolley-form is supported by additional rolling supports 14 on horizontal sections 25 of the skylight 18. The movable frame 21 is lowered with a gripping 23 gig.aro-cylinder 22 and is fed to the front end of the lower trolley-form. The spring-loaded L-shaped lever 15 of the catcher, by means of the hydraulic cylinder 16, rotates and releases the opening 8 of the heat chamber for the passage of the trolley shape. Then there is a simultaneous impact on the lower trolley-form of the ejector levers 26 under the action of their hydraulic cylinders 27 and the reverse movement of the movable frame 21 of the sniper. As soon as the trolley shape, with its additional rolling bearings, then falls on the inclined sections of the scraper 18, the ejector levers 26 are retracted. Subsequently, during the reverse movement of the movable frame 21 from below, the feeder takes place plane-parallel movement of the lower trolley form along

 the inclined part of the sculpt 18 and swivel

nx part 19 under the action of the co (5

an inclined position, and a package of forms in the guides of 10 g moves downwards and the lower trolley form relative to the subsequent displacement occurs, while the rollers 13 of the subsequent trolley shape interact with the lower one. As the lower trolley shape moves along the skylines, the hydraulic cylinder 16 returns to the initial position of the catcher lever 15, and the next trolley mold is installed on horizontal sections of fixed skylines 18. The lower molded trolley lowers to the rail track and the pusher 3 is fed to the talting station where the removal of the product from the trolley form and its preparation for the formation of the next product. Then the trolley mold 2 by the pusher 3 is fed to the post 5 of the molding and the cycle is repeated.

The conveyor line provides for the use of several heat chambers. In the case of unloading the car forms from the subsequent heat chambers, the rotary part 19 of the previous chamber in the previous chamber is set to a horizontal position and allows the free passage of the car form through the heat chamber.
