Abstract

The utility model relates to a vibrating concrete pipe making machine with a vertical core. The existing pipe making machine core mould is arranged on the hydraulic lifting device below a working bench, and the height of the whole machine is high; the mould is changed troublesomely, and besides, the pressure plate on the pipe making machine core mould is a lift type; the weight is heavy, and the energy consumption is big. The core mould of the device is changed to be a lift type, and the hopper, the pressure plate and a material moving rod are all arranged on a walking gantry frame. The electric hydraulic control is used to enhance the integration degree of the equipment component and the universality of producing the pipes with different sizes, and the structure is simple. A gravitational pressure plate is replaced with a hydraulic pressure plate to reduce the weight and improve the compactness of processing the end opening of the pipe; the energy consumption is low, the device is convenient to realize the linkage control, and the work efficiency is enhanced.

Description

Vibrating concrete pipe making machine with a vertical core

The utility model belongs to a kind of vertical core mould vibrating concrete pipe-manufacturing machine.

" concrete and reinforced concrete sewer pipe " book of Chinese building material association in December, 87 ejecting plate discloses a kind of vertical core mould vibrating concrete pipe-manufacturing machine commonly used at present for the 206th page, its groundwork principle is: will be fixed on the workbench with clip vertical with the tubular external mold of framework of steel reinforcement, a hydraulic lifting device is established in the workbench bottom, core is fixed thereon, during work, the hydraulic lifting device passes work top with core and rises along outer mold cavity, feed appliance is from external mold downward feeding suitable for reading, the core top is established a rotating vane material is pushed in the space between external mold and the core, the vibrator of installing makes core vibrate while rising in the core simultaneously, with the material jolt ramming between core and the external mold, when material is added to core top and external mold upper port when maintaining an equal level, with crane gear the one gravity platen that is provided with vibrator is pressed on the die orifice, lean on gravity and vibration concrete jolt ramming with port section, then gravity disk is hung away, fall core, enter form removal maintenance operation.The deficiency of this tuber is: the hydraulic lifting apparatus structure of (1) core is very complicated, and one group of rotation material toggling mechanism all will be established in each core top.(2) the gravity platen is big because of volume, Heavy Weight, and the crane gear power consumption that lifts it is big, inconvenient operation.(3) because workbench has the fixedly hydraulic lifting device of core, workbench needs a core height at least, adds the external mold height again, so strengthened the complete machine height.(4) dismounting, more mold exchange is more loaded down with trivial details, and it is very inconvenient particularly to change core.

The utility model aim to provide a kind of can reduce complete machine height and weight, simple in structure, cost is low, high efficiency, power consumption are low, the vertical easily core mould vibrating concrete pipe-manufacturing machine of mold exchange more.

Realize that the above-mentioned purpose technical solution is: the utility model comprises the tubular external mold 35 of the band framework of steel reinforcement of vertical installation, annular bed die 6, inside is equipped with the core 37 of vibrator, the mould secure component, platen 32, pay-off, travel switch, hydraulic electric appliance control system, it is characterized in that: described core bottom is inserted on the centralized positioning dish 5 that is fixed in workbench, high the rising of core crown center is coniform, the Jiong type portal frame 10 of one bottom band road wheel 9 is set across workbench, road wheel is positioned at the road wheel track 1 of workbench both sides, portal frame top is provided with and can be driven platen fixed mount 15 that move up and down and that vibrator 29 is housed by the described hydraulic system of band pressure regulator valve, described platen 32 is fixed on the platen fixed mount, portal frame top also is equipped with and can be driven and paste rod for stiring materials 31 that the core end face horizontally rotates by motor, rod for stiring materials top be fixed in the hydraulic transmission that portal frame top can drive its oscilaltion and link, a hopper 22 is also fixed on portal frame top simultaneously, its feed opening faces toward the core top, and is provided with by the emptying door 17 of hydraulic means controlling.

Operation principle of the present utility model is: with external mold, bed die, core is vertical be fixed in workbench after, the hydraulic system that starts portal frame top descends rod for stiring materials to be adjacent to the core end face rotates then, the emptying door of hopper end opening is opened blowing simultaneously, rod for stiring materials pushes material in the toroidal cavity of external mold and core formation, vibrator vibration in the core simultaneously, the material vibratory compaction that constantly will add, wait to feed in raw material when rising to port, the startup Hydraulic Power Transmission System will go up platen decline and be pressed on the port, and utilize pressure regulator valve control to give the port certain pressure, vibrator vibration on the platen fixed mount with the material jolt ramming of upper port, starts hydraulic transmission then and makes platen simultaneously, driving lever leaves the mould top and rises, at last portal frame is pushed open,, will be hung other places with the drip molding of external mold again and enter the form removal steam curing process with the crane gear core of slinging.Change when producing the pipe fitting size, only need replacing external mold, core, platen to get final product, rod for stiring materials can be flexible with the bolt adjustment as required.

The utility model is simple in structure, reduced the complete machine height, platen changes the hydraulic pressure platen into by the gravity platen on it, not only alleviated weight, it is low to consume energy, and can further improve the density of pipe port, the utility model is with hopper, rod for stiring materials, last platen fixed mount and hydraulic transmission that vibrator is housed push up with being located at same walking portal frame, not only be convenient to realize fluid pressure linkage control, improve automaticity, strengthened the integrated level of equipment simultaneously, make the concrete pipe of producing different tube diameters adopt same set of feeding, vibration pressurization and hydraulic pressure electrical control mechanism, having reduced to change needs more mold exchange when producing the pipe fitting specification, the fussy degree of parts has improved the versatility of equipment.
