Description
Technical field
The utility model belongs to tubing manufacture technology field, particularly relates to a kind of combined type circular ports out-of-roundness rectifier.
Background technology
PCCP---the abbreviation of " Prestressed concrete cylinder pipe ", is mainly used in large-scale water conservancy conveying engineering.Its manufacture craft comprises, and steel cylinder makes, concrete tube core is shaping, and cement mortar protective course tube core is wound around outside ring orientation prestress steel wire and steel wire makes four large operations.Wherein steel cylinder plays sealing and connects PCCP socket ring, socket hoop effect in PCCP.It is have wall thickness 1.5mm-2.0mm steel cylinder that steel cylinder makes, and two ends welding bell and spigot steel loop is made.Bell and spigot steel loop dimensional accuracy is that PCCP pipe installs and determines the most important guarantee of its sealing, and specification regulation socket dimensional accuracy tolerance completes bell and spigot sealing just cannot ensure for (-1.0 ~ 0) local out-of-roundness < 3 ~ 5mm. exceeds this value Pipe installing.
In prior art PCCP steel cylinder make in due to fabrication error, apparatus factor, be with faucet steel cylinder in place inaccurate in a mold in process operations process, complete in suspender hoisting process to problems such as socket end collisions, socket end circularity can be caused to exceed standard, namely its out-of-roundness is greater than specification given size, and oversize meeting makes this pipeline become waste product, adopts traditional flame shaping, hammering etc. method is time-consuming also can cause concrete destruction.
Summary of the invention
The defect that the utility model exists to overcome prior art, the purpose of this utility model be to provide a kind ofly be convenient to dismantle, be convenient to carry, easy for installation, the circular ports out-of-roundness rectifier that can not damage tubing.
The technical solution that the utility model adopts is a kind of combined type circular ports out-of-roundness rectifier, comprise jack, crossbeam, left lever and right pull bar, the rise push rod of described jack withstands on bottom crossbeam, described crossbeam two ends are connected with left lever one end with right pull bar respectively, and the other end of described left lever and right pull bar is provided with bayonet socket.
Described left lever and right pull bar are provided with fixing hole, and described left lever is connected with crossbeam by fixing hole with right pull bar.
Described bayonet socket arranges fastening adjustment bolt.
Described jack is mechanic jacks, and described mechanic jacks adopts the mechanic jacks being more than or equal to 10 tons.
The bottom of described jack is provided with jacking block.
Compared with prior art, the beneficial effect that the utility model has is: adopt detachable, modularity makes adjuster carry, easy for installation, adjustment two, left and right clearance between tiebars can be applicable to the mouth of pipe out-of-roundness correcting different length simultaneously, this mechanism and bearing calibration, adopting the fine adjustment of mechanical jack to apply pressure can not destroy by other soldering openings of line up place, avoids traditional method such as employing flame shaping, hammering and can cause concrete destruction and destroy steel crystal particle structure.Hardwood block is set between jack and the mouth of pipe, because hardwood block has the effect of certain buffering, jack and tube wall is also served to the effect of protection.The use of this aligning gear, be not limited to field, place, do not need electric power, the devices such as oxygen-acetylene, carry and install correction conveniently, easy and simple to handle, reduce mouth of pipe correction time,, than traditional flame or hammer mode enhance productivity at least 5 times of techniques, reduce labor strength, line up calibration result reduces well the destruction of line up concrete and steel construction.

Fig. 2 is the structural representation of this practical left lever and right pull bar.
In figure:
1, jack, 2, crossbeam, 3, left lever, 4, right pull bar, 5, jacking block, 6, bayonet socket, 7, fixing hole, 8, rise push rod, 9, fastening adjustment bolt, 10, the mouth of pipe corrects section.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of combined type circular ports out-of-roundness rectifier, comprise jack 1, crossbeam 2, left lever 3 and right pull bar 4, the rise push rod 8 of described jack 1 withstands on bottom crossbeam 2, described crossbeam 2 two ends are connected with left lever 3 one end with right pull bar 4 respectively, and described left lever 3 and the other end of right pull bar 4 are provided with bayonet socket 6.
Described left lever 3 and right pull bar 4 are provided with fixing hole 7, and described left lever 3 is connected with crossbeam 2 by fixing hole 7 with right pull bar 4.
Described bayonet socket 6 arranges fastening adjustment bolt 9.
Described jack 1 is mechanic jacks, and described mechanic jacks adopts the mechanic jacks being more than or equal to 10 tons.
The bottom of described jack 1 is provided with jacking block 5.Described jacking block 5 is specially hardwood block.Because hardwood block has the effect of certain buffering, jack and tube wall are served to the effect of protection.
The utility model can regulate according to socket end deflection (circular radian) size, and the mouth of pipe of suitable different bore, when the mouth of pipe produces out-of-roundness, according to the length of out-of-roundness, left lever 3 and right pull bar 4 bayonet socket 6 are stuck on the mouth of pipe, bayonet socket 6 arranges fastening adjustment bolt 9, pull bar is made to keep vertically standing on mouth of pipe place, 10 tons of mechanic jacks are placed wanting correction position, when jack 1 rise push rod 8 withstand on crossbeam 2 time, adopt jack 1 reaction force by deformation section toward extrapolation, this thrust makes deformation section produce outside circular deformation amount, when thrust is greater than mouth of pipe plastic deformation, lay down jack 1 thrust, the circular deformation that deformation section produces would not bounce back, by repeatedly finely tuning the correction of mode of texturing like this, the out-of-roundness of this section is progressively made to be consistent with theoretical circularity, reach the object correcting mouth of pipe circularity.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
