Description
Technical field
The invention belongs to industry construction equipments such as building, electric power, relate to a kind of tubular coagulation soil prefabricated component that is applicable to specifically and prepare the screw with long screw pitch blade concrete pump that uses in the equipment.
Background technique
In the construction of industries such as building, electric power, the use of tubular coagulation soil prefabricated component such as concrete pipe pile, concrete line bar is very general, its preparation process mainly contains two kinds of die sinking cloth and matched moulds clothes, because the matched moulds distributing technique adopts behind the matched moulds by transfer pump from the automatic spread concrete of mould inside, die sinking dress mould number of times and mould loss have been reduced, avoided the nonuniformity of artificial die sinking cloth and the damage that bar construction in the prefabricated component is caused, also avoided simultaneously because the preform surfaces mass defect that matched moulds forms easily behind the cloth.China's tubular coagulation soil prefabricated component adopts the die sinking distributing technique mostly at present, main cause is that the automatic paving system of matched moulds distributing technique concrete also exists some technical problems, and screw with long screw pitch blade concrete pump is exactly a key link in the automatic paving system of concrete.
Summary of the invention
Purpose of the present invention provides a kind of screw with long screw pitch blade concrete pump at existing deficiency in the above-mentioned prior art just.
Purpose of the present invention can realize by following technique measures:
Screw with long screw pitch blade concrete pump of the present invention comprises the pump housing, and to be installed in the spiral conveying mechanism that drives by power plant in the pump housing inner chamber with pump housing coaxial line mode; The described pump housing be to constitute by the feed zone of cylinder barrel shaped structure and the discharging section of cone barrel type structure, be connected with the carrier pipe of a cylinder barrel shaped structure at the discharge port place of cone barrel type structure discharging section; Described spiral conveying mechanism is by having shaft part and no shaft part to constitute jointly, described have shaft part to be arranged in pump housing inner chamber, described no shaft part is positioned at the tube chamber of carrier pipe, and have the longitudinal section projection of shaft part helical blade and pump housing lumen shaft similar to sectional shape, the longitudinal section projection and the carrier pipe lumen shaft of no shaft part helical blade are similar to sectional shape; On the cylinder barrel shaped structural charge section of the described pump housing, be provided with hopper in mode perpendicular to pump housing axis.
The hydraulic power system of power plant described in the present invention for constituting by oil hydraulic motor and oil hydraulic pump; Described hydraulic power system realizes closed loop control by the central control system that the PLC controller constitutes.
The pitch of no shaft part helical blade described in the present invention compares greater than 2 with external diameter.
Working principle of the present invention is as follows:
The distance of can growing carrier pipe described in the present invention stretches in the prefabricated component mould behind the matched moulds, and the transmission shaft of spiral conveying mechanism is connected with the output shaft of hydraulic power system, and the helical blade of spiral conveying mechanism is the wear-resisting steel plate manufacturing.According to concrete pump pumping principle, have the shaft part helical blade can be effectively with the transmission and concrete transmission in the hopper in carrier pipe, allowing partial material to return during no shaft part helical blade conveying material allows, delivering concrete runs into and can effectively dodge when the material card blocks up in long distance pipe, avoids stuck or the damage pump housing.
Transfer pump of the present invention is realized closed loop control by central control system, regulates output power automatically with real-time control concrete discharge capacity by the pressure that detects hydraulic power system through frequency variator.
Beneficial effect of the present invention is as follows:
Concrete pump of the present invention has the function of regulating pressure and control discharge capacity compared to existing technology, makes that the concrete distributing system can realize quantitatively, stablizes, reliable operation.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
The present invention is further described below with reference to embodiment's (accompanying drawing):
Screw with long screw pitch blade concrete pump of the present invention comprises the pump housing 1, and to be installed in the spiral conveying mechanism that drives by power plant in the pump housing inner chamber with pump housing coaxial line mode; The described pump housing 1 be to constitute by the feed zone of cylinder barrel shaped structure and the discharging section of cone barrel type structure, be connected with the carrier pipe 5 of a cylinder barrel shaped structure at the discharge port place of cone barrel type structure discharging section; Described spiral conveying mechanism is by having shaft part 2 and no shaft part 6 to constitute jointly, described have shaft part 2 to be arranged in the pump housing 1 inner chamber, described no shaft part 6 is positioned at the tube chamber of carrier pipe 5, and the longitudinal section projection of shaft part 2 helical blades and pump housing lumen shaft are arranged to sectional shape similar (this structure be for outward edge that makes shaft part 2 helical blades and pump housing internal chamber wall between form good mass transport matching relationship), the longitudinal section projection of no shaft part 6 helical blades and carrier pipe 5 lumen shaft are to sectional shape similar (this structure be for outward edge that makes no shaft part 6 helical blades and carrier pipe 5 internal chamber walls between form good mass transport matching relationship), and the pitch of described no shaft part 6 helical blades and external diameter are than greater than 2; On the cylinder barrel shaped structural charge section of the described pump housing 1, be provided with hopper 4 in mode perpendicular to pump housing axis.
The hydraulic power system 7 of power plant described in the present invention for constituting by oil hydraulic motor and oil hydraulic pump; Described hydraulic power system realizes closed loop control by the central control system that the PLC controller constitutes.
Transfer pump of the present invention is rotated by the transmission shaft (pump shaft) that oil hydraulic motor provides rotary motive power to drive spiral conveying mechanism by hydraulic power system, and pump shaft drives has the shaft part helical blade to rotate, and has the shaft part helical blade to drive no shaft part blade rotation; According to concrete pump pumping principle, have the shaft part helical blade can be effectively with the transmission and concrete transmission in the hopper in carrier pipe, do not have an axle screw with long screw pitch blade and in carrier pipe, rotate mass transport is paved in the mould of prefabricated component to the carrier pipe mouth of pipe; Whole process is by central controller controls.Allow partial material not return when not having axle screw with long screw pitch blade conveying material and allow, delivering concrete runs into the material card and can effectively dodge when stifled in long distance pipe, avoids stuck or damages the pump housing, and carrier pipe can be grown apart from the prefabricated component mould that stretches into behind the matched moulds; Central control system can realize closed loop control, regulates output power automatically with real-time control concrete discharge capacity by the pressure of detection hydraulic power system and by frequency variator.
