Description
Technical field
The present invention relates to the water test unit technical field of casting pipe, the specifically water of super large latus rectum cast tube part
Testing equipment more particularly to different structure form are pressed, and latus rectum is in the water test unit of DN1600-2200 pipe fitting.
Background technique
The cast tube part that existing hydrostatic testing machine can complete a certain specific latus rectum specification (DN latus rectum < 1600mm) suppresses examination
It tests.But the fuselage ring of such curved head type hydrostatic testing machine is triangle tilt frame, and side cylinder position is fixed, cannot be along frame
Lower movement is only applicable to the elbow water pressure test of specific standard, fixed angle；The fuselage frame of another kind of triplet type hydrostatic testing machine
Frame is vertical frame, and side cylinder driving mechanism can be moved up and down along column, but due to not having rotating cylinder, side cylinder does not have rotation
Function is only applicable to the straight-through and tee pipe fitting bulge test of specific standard.After pipe fitting latus rectum increases to DN1600 or more,
In the case that inside pipe fitting hydraulic pressure pressure is constant, according to pascal's principle, P=p*s, the power that hydraulic pressure generates increases, in order to balance
Water pressure needs equipment to be capable of providing bigger counter-force to guarantee the sealing effect when pipe fitting water pressure test.It pressurizes to equipment oily
The ability of cylinder, system pressure, more stringent requirements are proposed for fuselage overall stiffness；Existing hydraulic equipment is integral solder frame knot
Structure, after pipe fitting latus rectum > 1600, pipe fitting outer dimension super large, need equipment inner space is bigger, equipment contour dimension more
Greatly, the bearing capacity of moving trolley is bigger, the above carrying capacity for exceeding existing equipment.To create DN1600-2200 hydraulic pressure
For testing machine, to realize all tubular type bulge tests within the scope of the latus rectum, while guaranteeing equipment rigidity requirement, equipment
Outer dimension has reached 2200mm*10000mm*12000mm, and general frame weight is more than 120 tons.It will lead to using general frame
The part becomes the overweight part of ultra-wide, leads to a series of problems such as processing, lifting, transport, installation, or even can not transport to scene
Therefore, existing hydrostatic testing machine exists: 1, test pipe fitting specification is smaller, suppresses the latus rectum of pipe fitting generally in DN1600
Hereinafter, equipment own dimensions are smaller, rigidity is lower, and oil cylinder ability is smaller, can not achieve super large latus rectum (DN1600-2200) pipe fitting
The water pressure test；2, the pipe fitting for testing machine testing is in the form of a single, leads directly to pipe fitting and bend pipe tools need respectively different types of
It completes, takes up a large area in equipment, it is more to expend resource.
For it is above-mentioned the problems of in the prior art, researching and designing is a kind of novel for super large latus rectum cast tube part

On seat, prevent car wheel from bearing substantial load and damaging.
Further, guide rail uses light rail, and mechanical shutter is arranged in the end at guide rail both ends, plays limit Cheng Zuoyong.
Test method of the invention are as follows:
1, for the tee pipe fitting water pressure test, need the bell and spigot radial seal tooling in upper and lower, right (left side) three directions into
Row sealing, installs corresponding tooling respectively on master cylinder, left and right sides cylinder, trolley platen, and trolley carrying pressure testing pipe to be moved moves
After entering equipment, master cylinder is made to move down and pressurize, two mouthfuls above and below pipe fitting are sealed and compressed by tooling.Then by promoting oil
Cylinder adjusts side cylinder centre-height, so that right (left side) side cylinder center is aligned with tee pipe fitting interstitial hole center, then side cylinder is to Forward
It moves and pressurizes, pipe fitting interstitial hole is sealed and compressed by bell and spigot radial seal tooling.Right (left side) side passes through corresponding shoe work
Dress is contacted with pipe fitting, plays the role of balance right side cylinder thrust.
2, for leading directly to the pipe fitting water pressure test, it is only necessary to the tooling and sealing of upper and lower both direction.By adjusting square chest work
It fills to adjust the height of pipe fitting, to meet the water pressure test needs that all specifications lead directly to pipe fitting.
3, for the bend pipe tools water pressure test, the tooling and sealing of left and right both direction are needed, on left side cylinder, right side cylinder
Corresponding tooling is installed respectively, on trolley platen mounting and adjusting square chest and corresponding elbow bracket are adjusted by adjusting square chest combination
Whole elbow centre-height adjusts side cylinder tilt angle by rotary oil cylinder, is promoted to side cylinder driving mechanism by lift cylinder
Top dead-centre is simultaneously kept, and the cradle bottom surface for guaranteeing that cylinder braced frame in side is hardened above plate with upper soffit fits closely, then side cylinder
It moves forward and pressurizes, two hole of bend pipe tools is sealed and compressed by bell and spigot radial seal tooling.Various rule can be realized
The sealing of lattice elbow needs.
Above-mentioned three kinds of pipe fittings are that inside pipe fitting fills the water by low pressure water lines, in pipeline after carrying out pipe fitting seal operation
Gas be discharged by gas exhaust piping, water filling port and exhaust outlet are each provided in tooling.Pipe fitting closes ball valve after being vented, it
It is suppressed afterwards by high-pressure hydraulic pump for pipe fitting, hydraulic pressure is mainly the ranks such as 1.6MPa, 2.5MPa, 3.5MPa.Dwell time can be according to
Each batch of pipe fitting technique requires to execute.

In order to improve device load-bearing capability, bigger ability is arranged in the case where oil hydraulic system pressure is constant in the present invention
Master cylinder and side cylinder meet the carrying needs of higher hydraulic pressure counter-force.
In order to which the cast tube part of super large latus rectum specification, oversize to be placed in inside equipment, improves equipment and accommodate energy
Power, the present invention increases the frame size of equipment, and correspondinglys increase the rigidity of equipment, guarantees device framework in the water pressure test
It deforms smaller.
The problems such as ultra-wide in order to solve general frame is overweight, present invention employs separate assembling frame structures, will be whole
Subdivision is upper beam, column, pedestal three parts to body formula frame in place, is pre-tightened by multiple groups pull rod, multiple groups positioning key is determined
The pre- tight integration of seperated component is integral frame structure by the structures such as position, efficiently solves the processing, lifting, long distance of the overweight part of ultra-wide
From problems such as transports.
To sum up, applying the technical scheme of the present invention, it is in the prior art to solve: 1, test pipe fitting specification is smaller, and equipment is certainly
Body size is smaller, and rigidity is lower, and oil cylinder ability is smaller, suppresses the latus rectum of pipe fitting generally in DN1600 hereinafter, can not achieve super large
The water pressure test of latus rectum (DN1600-2200) pipe fitting；2, the pipe fitting for testing machine testing is in the form of a single, leads directly to pipe fitting and bend pipe tools
It needs to complete on different devices respectively, take up a large area, it is more to expend resource；3, it is easy to lead after integral frame structure amplification
Cause ultra-wide it is overweight, so as to cause processing, lifting, transport the problems such as.
