Description
Technical field
The invention belongs to nuclear power station non-destructive testing technology, and in particular to one kind is used for voltage-stablizer electrical heating elements group
The retracting device of part video check camera.
Background technology
In nuclear power station, voltage-stablizer major function is foundation and maintains pressure, it is to avoid reactor coolant is anti-
Answer boiling in heap.Water-vapour equilibrium temperature is controlled by means of heating and spraying, so as to keep required master cold
But agent pressure.When negative variation occurs in pressure, electrical heating elements produce steam, make reactor coolant loop
Pressure maintain one allow in the range of.Electrical heating elements operation reliable to nuclear plant safety plays ten
Divide important effect.
The minimal design life-span of electrical heating elements is effective work 20,000 hours, it is contemplated that the life-span is about 20 years.
With the growth of nuclear power station run time, the defect such as electrical heating elements are easily cracked, are recessed finally is led
Send a telegraph the failure of heating element heater.In inservice inspection electrical heating elements are carried out with the monitoring camera that video check is used
Head and detection camera are needed to reclaim, and the reliable of recovery is must assure that during recovery, prevent camera cable from returning
The fracture of receipts process is big, causes camera to damage.
The content of the invention
Check that camera reclaims dress it is an object of the invention to provide a kind of voltage-stablizer electrical heating elements component video
Put, it ensure that the reliable recovery of monitoring camera and detection camera.
Technical scheme is as follows：
A kind of voltage-stablizer electrical heating elements component video checks camera retracting device, including driving wheel, driven
The belt of wheel, connection driving wheel and driven pulley, and the reel being connected with the rotary shaft of driven pulley；Described
Rotary shaft is provided with two panels friction plate, spring and adjusting nut；One end of the rotary shaft of described driven pulley is set
There is fixed boss, described two panels friction plate is respectively arranged on both sides and the contact of driven pulley, the friction of inner side
Between piece is located on the inside of boss and driven pulley, the friction plate in outside is contacted with spring, and spring compression friction plate；
Described adjusting nut is located at the outside of spring, and adjusting nut is threadedly coupled with the rotary shaft of driven pulley.
In above-mentioned voltage-stablizer electrical heating elements component video checks camera retracting device：Described active
Reduction box and motor are connected in the rotary shaft of wheel.
In above-mentioned voltage-stablizer electrical heating elements component video checks camera retracting device：Described motor
For band-type brake motor.
In above-mentioned voltage-stablizer electrical heating elements component video checks camera retracting device：Described spring
For butterfly spring.
The remarkable result of the present invention is：Friction plate is arranged on the both sides of driven pulley, and spring is arranged on friction plate
Outside, between driven wheel side and friction plate produce frictional force, pass through adjusting nut and adjust butterfly spring
Thrust, reaches the effect of regulating friction force size, so that ensure that camera cable occurs overload and is pulled off,
And then cause camera reliable recovery.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
As shown in figure 1, the rotary shaft of driving wheel 3 is connected with reduction box 2, reduction box 2 and band-type brake motor 1
Connection.Band-type brake motor 1 provides driving force by reduction box 2 to driving wheel 3.
Driven pulley 5 is installed by axle in the top of driving wheel 3, driven pulley 5 and driving wheel 3 are connected by belt 4,
Driving wheel 3 drives driven pulley 5 to rotate by belt 3.The rotary shaft of reel 8 connects with the rotating shaft of driven pulley 5
Connect, when driven pulley 5 is rotated, drive reel 8 to rotate, so that the camera cable being connected with reel 8 be returned
Receive.
For reliable recovery camera cable, prevent cable from occurring overload and being pulled off, in turning for driven pulley 5
The medial end processing boss 10 of moving axis, a piece of friction plate 6 is respectively mounted in the both sides of driven pulley 5, inner side
Friction plate 6 is located between the inner side of driven pulley 5 and boss, and friction plate 6, butterfly are installed in the outside of driven pulley 5 successively
Shape spring 7 and adjusting nut 9.By adjusting nut 9, the thrust applied to butterfly spring 7 is adjusted, from
And adjust the frictional force between driven pulley 5 and friction plate 6.
Certainly, the friction plate 6 of inner side can also remove so that the inner side of driven pulley 5 is directly contacted with boss 10.
Adjusting nut 10 is merely able to adjust the frictional force of a piece of friction plate 6.
By adjusting the frictional force of the both sides of driven pulley 5, tension load when cable is recovered effectively is controlled,
And then cause camera reliable recovery.
