Description
Technical field
The present invention relates to a kind of waterproof test device more particularly to a kind of anticollision swing pipe water pouring test devices.
Background technique
When carrying out world waterproofing grade IPX test, need in sample two sides to wave semicircular swing pipe for 180 °
And it sprays water simultaneously to the swing pipe center of circle.Lesser sample can be visited and be completed in experimental cabin, relatively easy；But biggish sample,
Such as size can not be placed in experimental cabin and carry out at one two meters or so, it can only be in more spacious place span two
The large-scale swing pipe progress water pouring test of rice or so, internal diameter about 5cm.
Since the span of swing pipe is larger, and have to spray enough waters and hydraulic pressure to sample, therefore in swing pipe
Water route accounting is larger.In the operating condition, water-filled swing pipe weight is close to 24Kg, if the speed lower swing per second in pi/2, meeting
Personal Risk is caused to the testing crew on side.Simultaneously because center of gravity substantial deviation balance staff, torque when swing is very big, at 0 ° and
When 180 ° of position turns to, swing rod is broken with junction when being easy, and also torque feedback to motor can be reduced electricity
In the service life of machine, those skilled in the art are urgently to be resolved always and cannot achieve.
Summary of the invention
In order to solve the above-mentioned problems of the prior art, it is anti-on balance staff that it is an object of that present invention to provide a kind of centers of gravity
Collide swing pipe water pouring test device.
A kind of anticollision swing pipe water pouring test device of the present invention, including：Semicircular swing pipe and it is connected to pendulum
The bracket at pipe both ends, the swing pipe are connected by transmission shaft and bracket rotation, and control transmission shaft rotation is equipped in bracket
Motor；
The junction of the swing pipe and transmission shaft is extended connecting rod, and the connecting rod and swing pipe are in same plane,
Clump weight is arranged far from one end of swing pipe in connecting rod；The swing pipe gravity balance that the connecting rod and clump weight is used to will be filled with liquid arrives
Straight line where transmission shaft.
A kind of anticollision swing pipe water pouring test device of the present invention, the advantage is that, but how rotate, and be full of liquid
Swing pipe center of gravity after body maintains transmission shaft institute on straight line always.Since center of gravity is Chong Die with shaft, torque will not be generated
It feeds back on motor, is turned in 0 ° and 180 ° of positions more smooth and steady, while the service life of motor is also accordingly prolonged
It is long.
Preferably, the clump weight is axially movable on connecting rod and by the fixed relative position of lockable mechanism.Due to
The device of waterproof test can be used for carrying out sample the spray test of other liquid simultaneously, for example, spray acid/buck, salt water,
The plurality of liquid such as oil, and the density difference of various liquid is larger, if the density of water is only used to spray other liquid as counterweight object
There is deviation in the center of gravity that will lead to swing pipe when body, the technological deficiency in background technique occurs.By the opposite position of clump weight and connecting rod
It installs and is set to adjustable mode, the liquid that can adapt to various different densities completely uses device of the present invention.Even if single
It is single to use a kind of liquid of water, after device long-time service, due to the various mechanical reasons such as deformation, shaft offset in pipe, can also it lead
The deviation of gravity center shaft of swing pipe is caused, therefore is also required to the problem of being finely adjusted clump weight to adapt to deviation of gravity center.
Preferably, PLC controller is equipped in the bracket to connect with motor signal；In transmission shaft, torque sensing is set
Device, torque sensor are connect with PLC controller signal, for the torque signal of transmission shaft to be fed back to PLC controller；Described
PLC controller controls motor stopping after receiving the torque signal of torque sensor.In normal work, center of gravity adjusting has been carried out
Afterwards, other than 0 ° and 180 ° of steering position, other angles are not in the feedback of torque in rotation.If torque sensor
Receive the torque signal of non-zero, it was demonstrated that swing pipe touches other external things, such as meets people or encounter other component.At this time
PLC controller can send at once signal control motor and shut down, and prevent from further damaging the person or damaging other component.It is logical
Threshold value of the setting PLC controller to torque signal is crossed, the sensitivity of adjustable motor stopping is made according to real work needs
Optimal selection.
Preferably, the bracket is equipped with the infrared detector for detecting clump weight position close to the side of clump weight,
The infrared detector is connect with PLC controller signal.Since connecting rod and swing pipe are in same level, pass through clump weight
Position detection, can derive whether swing pipe returns back to upright position in a non-operative state.Detecting swing pipe in non-
When upright position, PLC controller can control motor running, and swing pipe is reset to vertically.Because when off working state, not having in swing pipe
There is liquid, if being in non-vertical position, so that clump weight generates biggish torque influence electrical machinery life to junction.
Preferably, the swing speed of infrared detector detection clump weight, and the swing speed of clump weight is fed back
To PLC controller；The swing speed that infrared detector is fed back and PLC controller are output to motor by the PLC controller
Slew rate signal is compared, and real time correction is to the slew rate signal of motor.The slew rate signal that PLC controller is output to motor is reason
Swing speed by value, and infrared detector feedback is the actual value of swing pipe, due to a variety of mechanical reasons, theoretical output valve and reality
Actual value often has deviation, therefore the swing speed that infrared detector detection clump weight is arranged can carry out in real time theoretical value
Closed loop feedback, when test result it is more accurate.
Preferably, further include a moving trolley, the same sample platform is fixedly installed by telescopic rod above the moving trolley.
For the sample of different width ratios, can be adapted to by adjusting the height of telescopic rod.Since test of the present invention fills
It sets and is generally used for testing larger-size sample, therefore is more convenient as the means of transport of sample using moving trolley.Sample
Telescopic rod below platform can in the case where swing pipe does not stop swinging, sample stage and sample are all dropped to than swing pipe at 0 ° or
Position that will be low at 180 °, then directly off spray space replacement sample after, then revert to again spray space promoted it is high
Degree carries out continuous test operation.
Preferably, the moving trolley and PLC controller communication connection；PLC controller is located at 0 ° or 180 ° in swing pipe
When position, control moving trolley removes or moves into the spray position of swing pipe from the side far from swing pipe；PLC controller is moved in control
During dynamic trolley, the position of infrared detector real time monitoring telescopic rod simultaneously feeds back to moving trolley.It can be stretched not adjusting
Sample is continuously replaced under contracting bar height and the non-stop-machine situation of swing pipe to be tested, and the same size model number of same batch is suitble to
Multiple and different samples between replacement experiment work.
Preferably, the moving trolley is equipped with the transmission mechanism of axial rotation telescopic rod, and telescopic rod drives sample stage rotation
Turn；PLC controller controls the revolving speed that moving trolley adjusts sample stage.Further increase the accuracy of sample.
