Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides an insulator spindle bending test machine, including moving frame car 1, remove flatcar 2, the insulator spindle is placed and is pressed from both sides 3, lead screw loader 4, controller 5 and sensor 6, be provided with three removal flatcar 2 in the moving frame car 1, be provided with controller 5 on the removal flatcar 2 of centre, controller 5 below is provided with lead screw loader 4, the bottom of lead screw loader 4 is provided with sensor 6, sensor 6 links to each other with controller 5, the insulator spindle that is provided with the centre gripping insulator spindle on the removal flatcar 2 of both sides is placed and is pressed from both sides 3.
The insulating rod placing clamp 3 adopts a clamping type nylon pulley.
The sensor 6 is arranged on a pressing plate arc, and the radian of the pressing plate arc is consistent with that of the insulating rod.
The controller 5 is provided with a control switch 51 and a display screen 52.
Before the device of the specific embodiment is used, the shell is reliably grounded, then the power supply is plugged, the power supply switch is switched on, and the device enters the control interface with the touch screen for a short time.
The first interface of the touch screen is a directory menu and is divided into a 2-class static bending resistance test and a dynamic bending resistance test, and the static and dynamic tests are divided into two types, wherein the pipe diameter is less than 28mm, and the diameter is more than 28 mm.
According to the DL/T976-2017 requirements: the static and dynamic load test of the insulating rod against bending is as follows (A):
| test article | Bending-resistant dead load N.m | Bending-resistant dynamic load N.m |
| Nominal outer diameter of 28mm or less | 108 | 90 |
| Nominal external diameter above 28mm | 132 | 110 |
And (3) test period: 12 months old
The method comprises the following steps:
the static load test should last for 1min without deformation and damage under the values listed in the table.
The dynamic load test should be run 3 times at the values listed in the table above.
The experimental arrangement is as follows (B):
distance between two supports in bending test
| Diameter of the pipe mm | Rod diameter mm | Distance between the two supports is mm |
| —— | 10～16 | 500 |
| 18～22 | —— | 700 |
| —— | 24 | 1000 |
| 24～30 | —— | 1100 |
| 32～36 | 30 | 1500 |
| 40～70 | —— | 2000 |
The using method comprises the following steps:
firstly, according to the specification of a sample, the distance between two flatcars is adjusted by referring to a table B, the two mechanical buttons which move forwards and backwards are operated on the middle control panel, and the moving distance can be directly read from the outer frame ruler. After the position is adjusted in place, the insulating tube is placed on a nylon pulley on the flat car.
And selecting corresponding items according to the specification of the test article and entering a test operation interface. Here, the pipe diameter is 20mm, the pipe diameter is less than 28, and the flatcar distance is 700 mm.
And clicking a static load entering button to enter an operation interface.
Defaulting a system: standard load 108N m, time 1min
And displaying real-time pressure, displacement, timing and static bending load.
The descending and ascending buttons adjust the action direction of the load arm, and the action is continued once and stopped once again.
And (5) clearing the force value, clearing the system initial force value, and clearing the initial displacement by the same displacement.
After the test article is installed, the load arm is adjusted until the load arm just contacts the insulating rod to stop, (at the moment, the radian of the pressure plate of the sensor is consistent with that of the insulating rod), the click force value is reset and the displacement is reset, and the real-time pressure displacement on the right side is zero at the moment.
And then clicking a test key, starting a static bending test by the system, when the bending load reaches 108 N.m, starting timing by the system, automatically unloading the system after 1min, returning to the position with the pressure of 0, finishing the bending static load test, and observing whether the insulating rod is deformed or damaged.
At which point the back key is clicked back on the trial inventory menu.
And clicking a dynamic load entry key to enter a dynamic test operation interface.
The first column of the dynamic test interface is the standard load, and the number of tests. The other parameters and operating parts are the same as the static load.
After the bending static load test is finished, the insulating rod directly enters into a bending dynamic test when the insulating rod is not deformed and damaged, a test piece is clicked after a click force value is cleared and a displacement clear initial value is cleared, the system automatically loads a force value to a standard load, the system is unloaded to the initial position immediately, the counting is 1 time, the second loading is started immediately, the system is unloaded to the initial value immediately when the gear loading load reaches the standard load, the counting is 2, and then the third load test is carried out.
And observing whether the insulating rod is intact or not to deform and damage after the test is finished.
And in the loading process, if the insulating rod is damaged, the exit key can be directly clicked, the current test is ended, then the ascending key is clicked to unload, the ascending key is clicked again after the unloading is in place to stop the unloading, and the insulating rod is directly confirmed to be unqualified.
The bending load test of the test pieces of other specifications can be performed by referring to the above procedure.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
