Description
Technical field
The utility model relates to a kind of porcelain strut insulator check test platform, and testing table detects with the porcelain strut insulator vibroacoustics in especially a kind of testing laboratory.
Background technology
Vibroacoustics detects porcelain strut insulator and has obtained preliminary application at present in the electric power porcelain strut insulator detects, and has obtained certain application achievements.Porcelain strut insulator carries out vibroacoustics while detecting test in testing laboratory, is generally that support insulator is upright or puts upside down in ground, then adopt the vibroacoustics checkout equipment to be detected.In this case, because ground is hard, and ground can not vibrate with support insulator in the vibration detection process, therefore the vibration of the exhausted gorgeous son of pillar is caused to obstruction, affects the accuracy of vibration detection result.
In order to weaken and to eliminate the impact brought in the face of the constraint of support insulator etc. by ground, one of method adopted at present is to utilize the device of tightrope class to leave support insulator under order ground, allow the method that support insulator can free vibration in testing process, although this method can reduce the impact of the constraint such as ground on testing result, exist the exhausted gorgeous son of pillar to rock and be difficult to the problem of the application of force.
Therefore, for this situation, a kind of porcelain strut insulator vibroacoustics of utility model detects testing table, for the vibroacoustics detection of porcelain strut insulator testing laboratory.
The utility model content
For the problems referred to above, the purpose of this utility model is in vibroacoustics detects, owing to being subject to external constraint, to cause the inaccurate of testing result to provide a kind of porcelain strut insulator vibroacoustics to detect testing table for fear of porcelain strut insulator.
The utility model solves the technical scheme that its technical matters adopts:
A kind of porcelain strut insulator vibroacoustics detects testing table, and the utility model feature is comprise a flute profile base and be installed on the thing-putting holder on base; Base adopts spring to be connected with thing-putting holder; And be provided with the horizontal air damping unit between base and thing-putting holder side direction, vertically be provided with the air damping device with vertical direction, at the thing-putting holder top, beam is housed.
The utility model spring is vertically installed and is individually fixed on base and thing-putting holder, and number of springs is 3～5.
Be separately installed with the air damping device of level and vertical both direction between the utility model base and thing-putting holder, air damping device and base and thing-putting holder all adopt chain connection.Can realize that base and being with of thing-putting holder are air-damped relative movable.
Be placed with beam on thing-putting holder of the present utility model, thing-putting holder adopts high-intensity light material to make, and beam adopts the good material of damping performance to make, and beam thickness is not less than 5mm, and support insulator is placed on beam.
The key issue that this utility model solves: the mechanism of this utility model is mainly to utilize the spring supporting thing-putting holder, support insulator is positioned on thing-putting holder again, avoid support insulator directly to contact with ground, because the constraint of ground in the face of support insulator avoided in the effect of spring, adopted air damping device simultaneously, place the conduct vibrations of ground and base etc. to support insulator, affected testing result.
The useful result of this utility model: this utility model has designed a kind of porcelain strut insulator vibroacoustics and has detected testing table, can avoid the impact of the external constraint such as ground on support insulator vibroacoustics testing result, improves the accuracy detected.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
