Description

river view; in fig. 4 - the same longitudinal view; in fig. 5 - trolley form, general view; in fig. 6 - the same plan view.

The double-haul conveyor line contains, on the upper rue, posts for turning 1 pallets of form-trolleys 2, devices 3 for opening and closing its longitudinal sides.

The molding stations of the line are equipped with concrete pavers 4, vibrating nozzles 5 and finishing machines: leveling bar 6, calibrating roller 7 and trowel disc 8.

The bottom line of the line is made in the form of a chamber 9 of trapezoidal longitudinal profile for heat treatment of products. At the ends of the chamber there is a lift 10 and a descendant 11 for transferring the form-carts from Rus to Rus.

The lift and descender are equipped with a pusher 12. On the upper line of the line there is a pusher 13 with a mechanical drive 14 and a hydraulic pusher-rammer 15.

The pivot post 1 (see Figs. 3, 4) consists of a pivot mechanism 16, a lifting and lowering rail track 17 with a hydraulic actuator 18 and devices for a connector 19 of the hydraulic trolley 20 of the form-trolley.

The trolley form 2 (see Figs. 5 and 6) consists of a pallet 21 with folding longitudinal 22 and fixed transverse 23 sides. The pallet contains four bearing pads 24 and running pads 25 in contact with the pillars, interconnected by longitudinal links 26 and cross links 27. The wheels 28 are attached to the running pads. On the pallet there are devices 29 for fixing it to the running pads trolleys.

The work of the two-story flow-conveyor line occurs in the following sequence.

Lifted to the top Rus by a lift 10, the form-trolley 2 by the pusher 12 is fed to the turning post 1, where using the levers of devices for the connector 19, the supporting running platforms 25 are fixed together with links 26 and 27 and the wheel 28 relative to the lifting and lowering paths 17 .

When the tracks 17 are lowered, the carriage 2 is lowered. During the lowering, the pallet 21 with the product is placed on the frame of the turning mechanism 16, and the undercarriage platforms 25 are separated from the supporting platforms 24 of the pallet and lowered so that the pallet 21 can rotate freely ° By means of the turning mechanism 16, the pallet with the product is rotated to a position in which the product with its long side is installed along the axis of the conveyor.

Then, the tracks 17 are raised, during which the contact joints of the support platforms 24 and 25 are made, after which the trolley forms 2 are removed from the turn mechanism 16 by further raising the tracks. Using the hydraulic actuator 20, the truck 2 is released from the arms of the connector 19.

The pusher 13 of the trolley form is moved from the turning post to the front of the standing trolley shape, after which all forms of the upper tusk are pushed one step equal to the length of the trolley shape, while concreting takes place at the molding posts.

using the paver 4, compacting the concrete with a vibrating nozzle 5, leveling the concrete with a bar 6, calibrating the product with a rotating roller 7, and finishing the surface of the product with a wipe disk 8.

The head carriage at the end of the travel stroke of the pusher 13 enters the zone of the second turn post 1, which is not reduced by I. Then the head form is pushed with the help of the pusher, retracted from the car form next to it for a distance sufficient for the head to freely rotate trolley forms. The center of the pallet is set above the center of the pivot mechanism. After that, the pallet and the support pads are separated, the pallet is rotated with the product by 90 ° to the position at which the short side of the product is installed along the axis of the conveyor. The process of separation, rotation and connection

The trolley molds at the second turn post are similar to those described above for the first turn post. Then, the head carriage is captured by the fist of the pusher 12 located on the depressor 11, and

fed to the platform of the descaler.

With the help of Reducer II, the trolley form is fed to the lower rus. Simultaneously with the turning and lowering of the head carriage form, the removal of the finished products and the closing of the longitudinal sides of the closing form truck with the help of device 3 takes place. After the removal of the form, the finished product is removed by a crane, cleaning and lubrication of the form. Form-trolley, lowered to the bottom

The pusher of the reducer is fed into the heat treatment chamber a step equal to the width of the mold. At the same time, the form-car at the second end of the chamber is captured by the fist of the pusher 12 of the elevator 10 and is fed to the platform

lift

The elevator 10 lifts the trolley shape with the finished product to the upper Rus, and the process is repeated. The proposed double-bed-sleeved conveyor line makes it possible to optimally combine the modes of molding and heat treatment of flat, large-sized products while improving the utilization of the production area.

Subject invention

Double Rusa Conveyor Line

for the manufacture of concrete products in

forms-trolleys, including preparatory operations located on the upper russa with devices for stripping and assembling the forms, molding posts with concrete pavers, vibrating nozzles and finishing devices, tunneling, for example, trapezoidal longitudinal profile, heat treatment chamber forming the lower Russian, elevator and reducer for translating forms - trolleys from rus to rus and rail rails located on each rus, characterized in that, with the aim of ensuring the possibility of forming articles with longitudinal transfer, and heat treatment — with lateral movement of form wagons, increasing the degree of utilization of the production area and line capacity, and, on the upper tusk, at the mating points with the elevator and descender, installed posts for turning the pallets with the products in the horizontal plane by 90 °, each of which equipped with a turning mechanism and lifting and lowering paths with devices for separating form-wagons, made vertically detachable with connector planes, passing through four support platforms along Don and four kolesnohodovye bearing pads connected

between each other, with longitudinal and transverse connections, each pallet being equipped with mechanisms for fixing it relative to the travel support sites in the direction of travel of the form carriages, and the values perpendicular to the distance between the centers of the support sites, the ruts and bases of the travel wheels are equal to each other.
