In operation, through the interior vibration of the shaping core pipe 17, peripheral concrete of an inner hole of the hollow plate is compacted further. So the goal of improving the strength to meet design requirements is achieved.

Description

Shaping machine for prestress hollow plate by pushing and extruding

The utility model belongs to building machinery, relates generally to the former of concrete core slab.

The concrete core slab production of prior art is divided into manual and mechanical two kinds.Because the manual production work efficiency is low, the cost height, labour intensity is big, and cored slab pressure amount instability, progressively eliminates.Mechanical Method is produced and to be divided into screw reamer and to push the moulding dual mode, because screw reamer is in forming process, and serious wear, thereby the cost of cored slab is improved, and the cored slab of producing does not sometimes reach the compression strength requirement.The cored slab pressure amount that the concrete core slab extrusion molding machine is produced is stable, and cost is lower, and as Chinese patent 88216375.2 and 89205784.X, its quality of producing product is all more reliable.But when cored slab thickness increased, promptly at present widely used 180 * 600 cored slabs increased 60mm than 120 * 600 cored slab thickness, and circular hole changes greatly, only outer brisance with push moulding; Concrete density around its interstitial hole is not enough, thereby whole plate intensity does not reach designing requirement sometimes.

The purpose of this utility model provides a kind of prefabricated concrete hollow slab when pushing moulding, mandrel can in shake, can fully increase the cored slab packing, improve cored slab quality and intensity, the cored slab make-up machine that meets design requirement.

The utility model is by the motor drives gearbox on frame, big connecting rod, slide block movement, and by big connecting rod drive small rod, belt feeder makes big hopper inner concrete carry to the small powder bucket, belt feeder be positioned at big hopper below, little hopper is positioned at the side-lower of big hopper, be fixed on the frame, formed clamp plate is fixed on the frame behind the small powder bucket, vibrator and calendar plate are positioned at after the formed clamp plate, compressor wire is by frame front end comb gusset, and the holder gusset under the organic frame adjusts the position, becomes rear on the lower side, center that core barrel is positioned at frame, and slide block can be along becoming core barrel to slide.In becoming core barrel, on the flexible axle by the bearings at both ends supporting, be fixed with one or more vibrations.Be fixed on the motor on the frame,, drive the belt pulley that is fixed on the coupling spindle front end that is connected with flexible axle, make flexible axle produce rotation at a high speed by belt.

The utility model compared with prior art has:

1, increase vibrations that flexible axle drives in becoming core barrel, make mandrel produce the high frequency micro breadth oscillation, make concrete quicken to flow, it is closely knit to reach plasticizing, thereby has guaranteed the designing requirement of cored slab.

2, enlarged the scope of application of extrusion molding machine, made complete machine structure more reasonable.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the schematic diagram of pre-stress hollow panel moulding apparatus, also is its most preferred embodiment;

Fig. 2 is the A-A cutaway view of Fig. 1;

Among the figure: 1 comb gusset, 2 motor, 3 gearboxes, 4 big connecting rods, 5 belt feeders, 6 big hoppers, 7 small rods, 8 pull bars, 9 little hoppers, 10 formed clamp plates, 11 electromagnetic shakers, 12 pitman shafts, 13 calendar plates, 14 ballast boxes, 15 holder gussets, 16 slide blocks, 17 one-tenth core barrels, 18 core pipe carriers, 19 frames, 20 road wheels, 21 belt pulleys, 22 connecting axles, 23 flexible axles, 24 bearings, 25 vibrations, 26 bearings, 27 side templates.

Comb gusset 1 is fixed in the front end of frame 19, and road wheel 20 is positioned at frame 19 front end both sides.Motor 2 drives big connecting rod 4 by gearbox 3 and moves, and it is reciprocating along the direction that becomes core barrel 17 and compressor wire that big connecting rod 4 drives slide blocks 16, and the concrete in the small powder bucket 9 is passed through formed clamp plate 10 and vibrator 11, extrusion modling on table rest.Simultaneously, the motion of big connecting rod 4 drives small rod 7 and pull bar 8 and makes belt feeder 5 motions, thereby makes the concrete that store in the big hopper 6 being transported in the small powder bucket 9 intermittently.Formed clamp plate 10 behind the small powder bucket 9 is mainly used in the cored slab moulding and adjusts cored slab thickness among a small circle.The motion of small rod 7 drives calendar plate 13 by pitman shaft 12 and do upper and lower intermittent movement among a small circle, thereby improves the quality on cored slab surface, reduces the wearing and tearing of calendar plate 13.Holder gusset 15 is positioned at below the compressor wire of frame 19 front ends comb gusset 1, is used to adjust the horizontal level of compressor wire, to guarantee that compressor wire is at concrete protective layer thickness.Vibrator 11 ceaselessly vibrates in the course of the work, can increase concrete packing, thereby reaches the purpose that improves cored slab intensity.Ballast box 14 is for the weight before and after the balance make-up machine.

On the flexible axle 23 in becoming core barrel 17, be fixed with one or more vibrations 25, shaking sub 25 two ends has bearing 24 and 26 supportings.Belt pulley 21 connects with flexible axle 23 by a connecting axle 22.At work, motor drives belt pulley 21 motions by belt, by flexible axle 23 rotations, makes sub 25 high-speed motions of vibrations, becomes core barrel 17 to produce the high frequency micro breadth oscillation within the specific limits.Like this,, can further improve the packing of cored slab endoporus surrounding concrete, reach the purpose that improves cored slab quality and intensity by becoming the vibration of core barrel 17.

Through verification experimental verification, adopt the concrete core slab intensity of make-up machine production of the present utility model to improve greatly, reach designing requirement fully, can satisfy the design needs.
