Background technology
Prestressed concrete cylinder pipe (Prestressed Concrete Cylinder Pipe) is called for short PCCP, is a kind of novel rigidity tubing.It is the strong concrete tube core winding compressor wire with steel cylinder; spray is with cement mortar protective course; adopt steel bell and spigot; welded together with steel cylinder; fluted and the cushion rubber of bell and spigot has formed the flexible joint of slidingtype cushion rubber; be the composite construction that steel plate, concrete, high tensile steel wire and cement mortar different materials form, have steel and concrete characteristic separately.According to the difference of steel cylinder position in tube core, can be divided into two kinds: lined Prestressed concrete cylinder pipe (PCCPL), embed-type Prestressed concrete cylinder pipe (PCCPE).The characteristic such as Prestressed concrete cylinder pipe has rational composite construction, bear that interior external pressure is higher, joint tighness good, shock resistance is strong, convenient and quick construction, antiseptic property are good, easy to maintenance, paid close attention to by engineering circles, being widely used in long distance water transfer main line, pressure inverted-siphon, urban water supply engineering, industry has the waterline of pressure, electric power plant circulating water engineering sewer pipe, pressure blowdown main etc.Compare the advantage such as PCCP has applied widely, and the economic life is long, anti-seismic performance good, easy for installation, operating cost is low, substantially water-tight with tubing in the past.
The PCCP aqueduct wire prestressing machine jacking mechanism that present people generally acknowledge all adopts screw rod to hold out against mode.The screw rod jacking mechanism is comprised of screw arbor assembly and power source, and its pressure and power source have direct relation, and when the power of power source surpassed the holding capacity of screw rod, screw rod just easily damaged, so only have the size that strengthens screw rod to improve pressure.Twine silk at PCCP aqueduct prestressing force and hold out against in the equipment, if the pressure of PCCP aqueduct does not reach requirement, the prestressing force that can't finish the PCCP aqueduct twines silk or does not reach its desired prestressing force and twines a requirement.The transmission efficiency of screw rod is low, and its flank of tooth easily weares and teares, and cost is also high, and maintenance is difficulty relatively also.When long-term batch production same product, screw rod will use same position for a long time, so just more easily accelerates the concentrated wear of screw rod, finally causes screw rod to hold out against inefficacy, brings potential safety hazard to production.And maintenance each time, maintenance fitter's workload is all larger, and delays normal production.
General holding device is generally mechanical screws and holds out against, because it is low to hold out against efficient, holds out against in the work and easily loses efficacy, and causes dangerous.This operation pressure requires very large, so the fastening screw flank of tooth often damages, service life is low, and larger maintenance cost is high again for workload during maintenance.Therefore, be necessary the structure of holding device is improved.
The utility model content
The purpose of this utility model provides a kind of PCCP aqueduct wire prestressing machine hydraulic pressure holding device, twines yarn quality to increase work efficiency with product prestressing force, increases processing safety, reduces maintenance cost.
The utility model is that the technical scheme that its technical problem of solution adopts is,
PCCP aqueduct wire prestressing machine hydraulic pressure holding device, include be used to holding out against holding out against of PCCP aqueduct and coil and fixed disk, hold out against dish and the setting of fixed disk subtend, be positioned at PCCP aqueduct both sides, also include hydraulic mechanism, hydraulic mechanism with hold out against dish and join, hydraulic mechanism promotes to hold out against dish and the PCCP aqueduct is held out against is holding out against between dish and the fixed disk.
Also include frame, hydraulic mechanism is located on the frame.
Hydraulic mechanism includes oil pump and oil cylinder, is linked to each other by high-pressure oil pipe between oil pump and the oil cylinder, and oil pump drives the piston rod movement in the oil cylinder, piston rod by power transmission shaft with hold out against dish and link to each other, drive power transmission shaft, make to hold out against dish and move.
Power transmission shaft is located on the supporting seat, and supporting seat is fixed on the frame by securing member.
Piston rod links to each other by removable syndeton with power transmission shaft.
The utility model has the advantage of, this hydraulic pressure holding device provides hydraulic power by hydraulic power unit, promote power transmission shaft by cylinder piston rod and promote again to hold out against dish, the PCCP aqueduct is held out against on fixed disk, and its pressure is large, holds out against reliable, safety, be quick on the draw and increase work efficiency, design ingeniously, easy to implement, can reduce maintenance cost.
