Time monitoring.
Slip electricity getting device video monitoring system, in addition to monitoring top sliding electricity getting device state, still needs to take into account and connects on the way
Touching net and the duty of neighbouring high pressure equipment, therefore the vertical angle of slip electricity getting device CCTV camera should take along with slip
The lifting of electric installation and the change of object of observation and face upward or nutation.
Being limited in scope of slip electricity getting device lifting, CCTV camera only need to be in the little scope with the horizontal certain angle
Inside make elevating movement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for sliding for above-mentioned the deficiencies in the prior art
The luffing mechanism of electricity getting device CCTV camera, its simple in construction, slip electricity getting device CCTV camera can be made at Vertical Square
To facing upward or nutation.
For realizing above-mentioned technical purpose, the technical scheme that this utility model is taked is:
A kind of luffing mechanism for the electricity getting device CCTV camera that slides, wherein: include base, screw rod, nut, slip
Electricity getting device CCTV camera, slip electricity getting device CCTV camera torr, rotating shaft, support, motor and motor bearing,
Described motor bearing is fixedly mounted on base, and described motor is arranged on motor bearing by hinge
On, described screw rod left end is connected with stepper motor output shaft by shaft coupling, and described nut is arranged on screw rod, described
Nut is arranged in slip electricity getting device CCTV camera torr by hinge, and described slip electricity getting device CCTV camera torr is led to
Crossing rotating shaft rack-mount, described support is arranged on base, and described slip electricity getting device CCTV camera is arranged on
In slip electricity getting device CCTV camera torr.
For optimizing technique scheme, the concrete measure taked also includes:
Above-mentioned support uses section bar welding processing to form.
Above-mentioned base uses rectangular flat version.
Above-mentioned slip electricity getting device CCTV camera torr uses " L " shape version.
Base is placed in roof.Drive slip electricity getting device CCTV camera torr by the nut of motor and be fixed on it
On slip electricity getting device CCTV camera motion.During realization, motor, under electric energy drives, will rotate via screw rod
The angled output of conversion of motion.The angle of rotary motion is exported the straight line changing into nut by the screw pair that screw rod and nut are constituted
Motion.Nut as driven member, be drawn near/push away under the driving of screw rod slip electricity getting device CCTV camera torr movable after
End.
When nut is when motor is close, drag slip electricity getting device CCTV camera torr and the monitoring of slip electricity getting device
The rear end of video camera moves downward, and makes slip electricity getting device CCTV camera face upward.When nut is when motor is close, drag
The rear end of slip electricity getting device CCTV camera torr and slip electricity getting device CCTV camera moves upward, and makes slip electricity getting device
CCTV camera nutation.By changing the size of each building block, adjust the luffing angle of slip electricity getting device CCTV camera
Scope.
This utility model simple in construction, by the control to step-by-step impulse, is finely divided controlled variable, it is achieved precisely fixed
Position, with low cost, control simple；Slip electricity getting device CCTV camera can be made to face upward in vertical direction or nutation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference therein is: base 1, screw rod 2, nut 3, slip electricity getting device CCTV camera 4, slip power taking dress
Put CCTV camera torr 5, rotating shaft 6, support 7, motor 8, motor bearing 9.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is further illustrated:
A kind of luffing mechanism for the electricity getting device CCTV camera that slides, wherein: include base 1, screw rod 2, nut 3,
Slip electricity getting device CCTV camera 4, slip electricity getting device CCTV camera torr 5, rotating shaft 6, support 7, motor 8 and stepping
Motor support base 9, described motor bearing 9 is fixedly mounted on base 1, and described motor 8 is arranged on by hinge
On motor bearing 9, described screw rod 2 left end is connected with motor 8 output shaft by shaft coupling, and described nut 3 is pacified
Being contained on screw rod 2, described nut 3 is arranged in slip electricity getting device CCTV camera torr 5 by hinge, and described slip takes
Electric installation CCTV camera torr 5 is arranged on support 7 by rotating shaft 6, and described support 7 is arranged on base 1, described slip
Electricity getting device CCTV camera 4 is arranged in slip electricity getting device CCTV camera torr 5.
In embodiment, support 7 uses section bar welding processing to form.
In embodiment, base 1 uses rectangular flat version.
In embodiment, slip electricity getting device CCTV camera torr 5 uses " L " shape version.
Illustrate: setting motor stepping angle as 1.8 °, the pitch of screw rod is l.Shaft axis (fixing point A), stepping
Motor with pin joint (fixing point B) line of motor seat with the angle of horizontal direction isFixing point A, nut take with slip
Pin joint (fixing point C) line of electric installation CCTV camera torr with the angle of slip electricity getting device CCTV camera axis is
ω, the luffing angle of slip electricity getting device CCTV camera is θ.Slip electricity getting device CCTV camera original state is level
During position, θ=0.When camera lens is higher than horizontal level, θ > 0；During less than horizontal level, θ < 0.Slip electricity getting device CCTV camera
