SU379392A1 - DEVICE FOR ALLOCATION OF SURFACE LAYER OF CELL-CONCRETE PRODUCTS - Google Patents

Description

The invention relates to the building materials industry and molset be used by cellular concrete plants, for example, in the manufacture of pas, non-agricultural agricultural structures with a bituminized surface layer.

A device is known for introducing additives into the surface layer of cellular concrete products, consisting of a self-propelled frame with a bunker for the additive mounted on it and a drive brush for breaking the cellular structure and introducing additives into the surface layer.

The known device allows the surface layer of non-reinforced articles to be processed in the stand method of their manufacture, when the molds are installed in one row between the rails along which the device is moving.

However, in the known device, the working body is rigidly set. At a given position, it cannot self-arbitrarily move vertically, which excludes the possibility of compaction of concrete near the upper reinforcement mesh of products. At the high position of the working body, the layer being processed is obtained with a small thickness too, and at a low position, the needles seize and turn the reinforcement out of the product.

The purpose of the invention is to increase the performance of the device.

For this purpose, the working body is made in the form of independent spring-loaded brushes, equipped with individual Zzlahs of vertical movement, between which a linear feeder of the ligature is mounted, and installed with the possibility of reciprocating motion in two mutually perpendicular directions; in addition, on the frame of the device are mounted copiers and adjustable fixators catchers.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - then

same, cross section; in fig. 3 - the same, top view.

The device consists of a rigid frame / on which rollers 2 and adjustable clamps-catchers 3 are fixed. Rollers 2 move platform 4, on which silo 5 is strengthened for dopant, drive 6 with drum 7 on which cable 8 is wound. Cable 8 bends around rollers 9 and attached to the frame. When winding, one end

the cable on the drum platform 4 moves over the rollers 2 along the frame /. Rollers 10 are attached to the pils side of platform 4, along which plate 11 moves with brushes 12 fixed on it. Metal needles 13 are attached to brushes. Brushes 12 are connected to plate 11 by springs 14 and bolts 15. In the lower position, the brushes are fixed with nuts 16. Through a connecting rod 17 and the crank 18 of the brush 12 are kinematically connected to the drive 6, which ensures their horizontal oscillations. Brushes can have an independent drive, ensuring the movement of each brush in its optimal mode. The brushes 12 are connected by ropes 19 with the collar 20, on which the handle 21 and the tooth 22 are fixed. By turning the handle 21, the spring-loaded brush 12 is raised to the required height and the nut 16 fixes the optimum position of the brushes. The frame / reinforcers 15 are secured to turn gate 20 (using tooth 22) and lift the brush at the moment it reaches the edge of form 24. Ligature feeder 25 is connected to brushes 12, which serves to dispense and relieve viping-20 no dispersed dopant from the bunker 5. The brushes 12 are made in the form of long strips and reinforced on both sides of the slot of the bunker 5. This allows the doping during movement of the platform 4 both at 25 one side and the other, and also provides a more complete development of the entire surface products. The device works as follows. Frame 1 with the knots installed on it is placed on the mold 24, into which the concrete mixture is poured. During the installation of the frame, the safety catches 3 slide along the sides of the mold and ensure accurate installation of the device. Then the platform 4 is placed 35 in the extreme position, turning the handles 21, lower the brushes 12 to the required depth and fix them with nuts 16. The alloying additive is loaded into the hopper 5 and. the actuator 6 is turned on. The brushes 12 at this 40 start to perform reciprocating movements along their length (i.e., across, to the mold), the feeder 25 feeds the additive onto the surface of the product, platform 4 begins to move 5 to the opposite end of frame 1. At the same time The front (in the direction of movement of the platform 4) brush 12 loosens the cellular concrete, a dopant is added to it, and the second brush mixes it with a chewing mass and compacts the layer of cellular concrete. When platform 4 reaches the opposite frame / sheep, tooth 22 of front gate 20 will be pressed into copier 23 and lift the front brush. In this case, the second brush will process the surface layer to the end of the product. The presence of springs 14 provides the possibility of spontaneous elastic lifting of the brushes in case of their engagement with the reinforcement, which prevents breakage of the device and the safety of the reinforcement. When the doping process is completed, the device is removed from the mold by a crane and placed on the next mold. In this case, the adjustment of the position of the brushes and the idle movement of the platform 4 is no longer required. The processing cycle lasts 6 minutes. When using the aggregate technology, the device can be suspended on a stationary lifting mechanism, the subject of the invention 1.
