Description
Technical field
The utility model is related to a kind of pendulum mechanical impact experimental rigs, are set more particularly, to middle pressure metal enclosed switch
Standby and control device mechanical impact experimental rig, belongs to electrical testing technical field.
Background technology
Many products are being used, are being loaded and unloaded, can all impacted in transportational process.The magnitude variations of impact are very big and with multiple
Miscellaneous property, therefore impact and collision reliability test are suitable for determining the weak link of machinery, examine the complete of product structure
Property.In environmental test, vibration, impact and collision are all can be as a kind of effective measuring means of product itself structural strength.
National standard has specially carried out the protection to extraneous mechanical collision point to electrical equipment shell of the rated voltage no more than 72.5kV
Grade defines the degree of protection code of IK01~IK10 according to the difference of collision energy.
At present, the utensil of mechanical impact experiment is broadly divided into three kinds：Pendulum, spring-hammer type, vertical drop hammer type.Vertically fall
Hammer is not suitable for medium voltage switchgear equipment, and the ram energy of spring-hammer type is usually no more than 2J, therefore is pressed in measuring station progress
Pendulum mechanical impact device is used when the mechanical impact of switchgear and control device is tested more.Impact component is put during experiment
Discharged after to certain altitude, swung along balance staff hit test product surface under the effect of gravity, and pass through select impact component quality with
Obtain different Impact energies.
Utility model content
The utility model provides a kind of pendulum mechanical impact experimental rig of portable, automatic display Impact energy.
A kind of pendulum mechanical impact experimental rig of utility model, primary structure include：Fixing device, electromagnet sucker,
Balance staff, swing rod, impact component, angular displacement sensor, intelligent display device, rolling bearing.Fixing device bottom embeds electromagnet
Sucker, electromagnet sucker generates strong magnetic-adsorption and is fixed on test specimen after energization；Balance staff is horizontally mounted by rolling bearing
On the securing means, one end is connect with angular displacement sensor；Swing rod be certain regular length rigid thread bar, threaded upper ends with
Balance staff is connected, and lower end is connected with impact component；Swing rod and impact component collectively form the pendulum of mechanical ram, can be around pendulum
Axis is maintained in a vertical plane and swings, it is made to obtain certain falling height by portable impact component, in gravity after release
The lower whereabouts bump test sample surfaces of effect；When balance staff rotates, the angular displacement sensor being attached thereto obtains angle signal and turns
Electric signal is turned to, signal is acquired by the intelligent display device on fixing device top, impact energy is directly displayed after signal processing
Measure grade.
Pendulum mechanical impact experimental rig described in the utility model is small, easy to remove, suitable for volume it is larger,
Mobile high-voltage switch equipment and control device are difficult to, corresponding impact energy is obtained by the falling height for adjusting impact component
Amount, can be used for a variety of test parameters in the case where being changed without impact component, have good versatility.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 and Fig. 2 is the front view and side view of the pendulum mechanical impact experimental rig of the utility model respectively.
In figure, 1 is fixing device, and 2 be electromagnet sucker, and 3 be balance staff, and 4 be swing rod, and 5 be impact component, and 6 be angular displacement

Specific embodiment
As shown in Figure 1 and Figure 2, pendulum mechanical impact experimental rig described in the utility model, primary structure include：Gu
Determine device 1, electromagnet sucker 2, balance staff 3, swing rod 4, impact component 5, angular displacement sensor 6, intelligent display device 7, the axis of rolling
Hold 8.
1 bottom of fixing device embeds electromagnet sucker 2, and strong magnetic-adsorption is generated after energization and is fixed on test specimen；Pendulum
Axis 3 installs on the securing means 1 by rolling bearing 8, and center is connected with 4 threaded upper ends of swing rod, impact component 5 and swing rod
4 lower threads are connected, and swing rod 4 and impact component 5 collectively form pendulum, can be maintained in a vertical plane and put around balance staff 4
It is dynamic, it is made to obtain certain falling height, the bump test that falls under the effect of gravity after release sample table by portable impact component 5
Face；3 one end of balance staff is connected with angular displacement sensor 6, and angular displacement sensor 6 obtains angle signal and is converted into when balance staff 3 rotates
Electric signal；Intelligent display device 7 is horizontally arranged at fixing device top, and is electrically connected angular displacement sensor 6, collects angle position
After the signal that displacement sensor 6 exports Impact energy grade is directly displayed through processing.
Pendulum mechanical impact experimental rig described in the utility model be applied to medium voltage switchgear equipment and control device into
During row experiment, specific implementation method is as follows：
First, by mechanically moving impact test device to medium voltage switchgear equipment and control device, suitable rum point is selected,
Percussion device is placed in test specimen surface appropriate location, and powers on and allows percussion device absorption on test specimen；
Second, portable impact component 5 makes it slowly rise, while observes the Impact energy shown on intelligent display device 7
Grade；
Third when impact energy magnitude is shown as the experiment IK grades of requirement, discharges impact component 5, makes it together with swing rod 4
Around the whereabouts bump test sample surfaces under the effect of gravity of balance staff 3；
4th, power supply is closed, removes mechanical impact experimental rig.
