Embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
Please refer to Fig. 1 and Fig. 2, whether the proving installation 100 of a kind of light fixture cable introducing device providing for embodiment of the present invention, produce displacement for testing the cable 210 of light fixture 200, thus the sealing of judgement cable introducing device.Described proving installation 100 comprises base 10, power part 20, fixed mount 30, locating rack 40, tautness meter 50 and pulling force portion 60.
Base 10 is roughly rectangular parallelepiped, for the proving installation 100 of light fixture cable introducing device is fixed on to ground.
Power part 20 is for providing power, and it is installed on base 10.Power part 20 comprises rotating disk 22 and rotating shaft 24.Rotating disk 22 is positioned at the end of rotating shaft 24.In the present embodiment, power part 20 is slowspeed machine, if rotating speed is 1r/min.
Fixed mount 30 is installed on base 10, for spacing tautness meter 50.Fixed mount 30 comprises at least one fixed leg 32, fixed station 34 and receiving space 36.
Fixed leg 32 is installed on base 10, for fixed mount 30 is supported in to base 10.In the present embodiment, fixed leg 32 is 4.
In other embodiments, fixed leg 32 is 1.
In other embodiments, fixed leg 32 can directly be installed on ground.
Fixed station 34 is roughly rectangular parallelepiped, and be installed on described fixed leg 32 above.Fixed station 34 is provided with through hole 340.In the present embodiment, through hole 340 is positioned at the zone line of fixed station 34.
When fixed leg 32 is while being a plurality of, receiving space 36 is surrounded by described fixed leg 32.When fixed leg 32 is one, receiving space 36 is located at the centre of fixed leg 32.In other words, receiving space 36 be arranged at described fixed leg 32 and be positioned at fixed station 34 below.Through hole 340 is communicated with receiving space 36, and the rotating disk 22 of power part 20 is contained in receiving space 36.
Locating rack 40 is for locating light fixture 200, and comprises at least one reference column 42, positioning table 44 and resettlement section 46.
Reference column 42 is installed on the fixed station 34 of fixed mount 30, for locating rack 40 is supported in to fixed mount 30.In the present embodiment, reference column 42 is 4.
In other embodiments, reference column 42 is 1.
Positioning table 44 is roughly rectangular parallelepiped, and be installed on described reference column 42 above.Positioning table 44 is provided with perforation 440.In the present embodiment, perforation 440 is positioned at the zone line of positioning table 44.
When reference column 42 is while being a plurality of, resettlement section 46 is surrounded by described reference column 42.When reference column 42 is one, the centre of reference column 42 is located in resettlement section 46.In other words, resettlement section 46 be arranged at described reference column 42 and be positioned at positioning table 44 below.Perforation 440 is communicated with resettlement section 46, and tautness meter 50 is contained in resettlement section 46.
Because being provided with fixed station 34 between resettlement section 46 and receiving space 36, thereby tautness meter 50 can be under the pulling force of pulling force portion 60 46 move to receiving space 36 from resettlement section, and fixed station 34 has limited tautness meter 50 motion in vertical direction.
Tautness meter 50 is for recording the pulling force of pulling force portion 60.During installation, light fixture 200 is installed on positioning table 44, and the cable 210 of light fixture 200 is fixed on the top of tautness meter 50 through perforation 440.
In the present embodiment, the top of tautness meter 50 is provided with latch closure 52, and cable 210 is fixed on latch closure 52.
Pulling force portion 60 is through the through hole 340 of fixed mount 30, and the bottom of tautness meter 50 is fixed in its one end, and the other end is fixed on the rotating disk 22 of power part 20.When power part 20 drives rotating disk 22 to rotate, pulling force portion 60 application of forces are to tautness meter 50.
In the present embodiment, pulling force portion 60 is wire rope.
During installation, base 10 is fixed on ground, power part 20 is installed on base 10 and rotating disk 22 is contained in receiving space 46, fixed mount 30 is installed on base 10 and is positioned at the side of power part 20, locating rack 40 is installed on fixed mount 30, tautness meter 50 is contained in the resettlement section 36 of locating rack 40, the cable 210 that light fixture 200 is installed on locating rack 40 and light fixture 200 is fixed on tautness meter 50 through the perforation 440 of locating rack 40, pulling force portion 60 is through the through hole 340 of fixed mount 30, and the bottom of tautness meter 50 is fixed in one end of pulling force portion 60, the other end of pulling force portion 60 is fixed on the rotating disk 22 of power part 20, thereby base 10, power part 20, fixed mount 30, locating rack 40, tautness meter 50 and pulling force portion 60 are just assembled into one.
In other embodiments, also can there is no base 10, power part 20 and fixed mount 30 are directly fixed on ground.
During test, first measure the diameter of light fixture 200 cables 210, and mark to the cable 210 of the cable introducing device porch of light fixture 200, the entrance level of described mark and cable introducing device.Then, open power part 20, rotating disk 22 is rotated, pulling force portion 60 applies pulling force to tautness meter 50 under the drive of rotating disk 22, when the power of tautness meter 50 demonstrations equals the power of regulation, closes power part 20 and makes cable 210 keep official hour under described pulling force.In other words, pulling force portion 60 under the drive of rotating disk 22 application of force to tautness meter 50 until the power that cable 210 bears equal regulation power and keep official hour.Check subsequently whether cable 210 produces displacement, and by the displacement of cable 210, weigh the sealing of the cable introducing device of light fixture 200.
In the present embodiment, the power of regulation is 20 times of cable 210 holding capacity, and official hour is 6 hours.
In the present embodiment, if cable 210 does not have bad student's displacement or displacement to be less than 6mm, the sealing of the cable introducing device of light fixture 200 meets the requirements.If the displacement of cable 210 is greater than 6mm, illustrate that the decrement between cable 210 and light fixture 200 housings is inadequate, the sealing that is cable introducing device is undesirable, and light fixture 200 is pyrotoxins, under the state of light fixture 200 normal work, light fixture 200 Inside Air Temperatures are up to more than 100 degree, vacating rain now or other abnormal occurrence the same day causes the temperature on light fixture 200 surfaces to decline, making light fixture 200 internal temperatures affected thereupon by it declines, cause producing negative pressure between light fixture 200 inside and outside, make rainwater enter lamp interior from cable introducing device, cause light fixture 200 to damage.And, if light fixture 200 is worked in flammable, explosive environment, because light fixture 200 is inner, occur abnormal, as there are drawing electric arc, short circuit etc. between light fixture 200 conductors, the spark that lamp interior produces can spread out of and pass in flammable, explosive environments by cable 210 from cable introducing device, cause blasting, generation can not be met the consequence of knowing.
The present invention utilizes the kinematic relation between rotating disk 22, pulling force portion 60, tautness meter 50 and cable 210, and the power that can make easily cable 210 bear equals the power of regulation, thereby can judge easily the sealing of cable introducing device.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
